Implementation of an Intervention to Improve Efficiency and Accuracy of Data Entry into the Veterans Affairs Central Cancer Registry at the Lexington VA Healthcare System
Background
The Veterans Affairs Central Cancer Registry (VACCR) is an information system, which collects and organizes data on Veterans with cancer for use in cancer surveillance activities, such as epidemiologic based efforts to reduce the overall cancer burden. Unfortunately, there was no structured standardized data acquisition method in place to ensure accurate or timely data entry of Lexington VA Healthcare System (LVAHCS) statistics. This quality improvement study evaluated the implementation of a Structured Query Language (SQL) code to identify specific documents in the Computerized Patient Records System (CPRS) electronic medical record with associated ICD-10 codes matching the reportable cancer cases in the Surveillance, Epidemiology, and End Results (SEER) program.
Methods
Outcomes Studied: Accuracy of the SQL code, rates of data entry into the VACCR pre- and postintervention. Cancer Program leadership collaborated with the VISN 9 Program Analyst to write a SQL code identifying the Veteran’s name; social security number; location by city, state, and county; and visit associated data such as visit location, ICD-10 code documented by the provider, and visit year. This code can be run manually or at a pre-determined cadence.
Results
A total of 3,099 incidences of cancer were entered into the VACCR by local Oncology Data Specialists (ODSs) for calendar years 2015 to 2022. This is approximately 238 cases yearly. After the intervention, 1692 patients were entered into the VACCR in 2023. This is an increased rate of data entry of 611%.
Conclusions
This study demonstrated the feasibility of implementing a SQL code to accurately identify Veterans with diagnoses matching the SEER list. Increasing accuracy of identification has led to increased data entry efficiency into the VACCR by local ODS staff. After proving the feasibility of this intervention, we are partnering with the VISN 9 Program Analyst to create a static, daily recurring report provided to the ODS staff. Future application of this intervention could also include expansion into other VHA sites, increasing their accuracy and timeliness of data entry. Overall, improving the timeliness and accuracy of the VACCR would subsequently improve the ability of the VHA to target interventions aimed at reducing the overall cancer burden.

Data Elements Captured in Breast and Gynecologic Oncology System of Excellence Health Informatics Tool
Background
The VA National Oncology Program (NOP) Breast and Gynecologic Oncology System of Excellence (BGSOE) aims to ensure that Veterans with breast and gynecologic cancers receive state-of-the-art, guidelineadherent, Veteran-centric, timely, and well-coordinated care. Achieving these aims relies on a national multidisciplinary Cancer Care Navigation Team that provides tele-oncology navigation services. The teams connect with Veterans to identify and support clinical, psychological, system, coordination-related needs. To assist the navigation team to find these relatively rare diagnoses within VA, we developed a health informatics tool (HIT) that automatically identifies patients with breast or gynecologic cancers, displays demographic and clinical information, and facilitates systematic needs assessment and care coordination and tracking.
Methods
We used multiple frameworks to ensure alignment between HIT mission and coordinator workflow. A separate view was provided for each phase of the workflow: assessment of Veteran eligibility, intake assessment, and care coordination and tracking. Algorithmic identification of candidate Veterans was validated to ensure coordinators were not inundated with information on Veterans outside the scope of the program. User interface was implemented in accordance with Lean principles applied to HIT design, with close attention to information inventory, efficient user motion, information transportation, and avoidance of overprocessing.
Results
From January 1, 2021, to March 6, 2024, the HIT captured 5,561 breast cancer and 1,663 gynecologic cancer patients. 908 patients were reviewed by the coordinator, of whom 817 patients had a correct diagnosis assigned by the screening algorithm. From these, 332 patients were added to the intake process. The intake process is pending for 207 patients and complete for 102 patients; 23 patients declined intake. For patients who have completed intake, we have captured information that includes Veteran demographics, social history, insurance details, medical history, family history, hazards, barriers, and information specific to BGSOE care coordination.
Conclusions
We applied a novel framework to design and implement mission-driven, workflow-aligned HIT that achieves high user efficiency using Lean principles. This facilitated an exciting new model in tele-oncology care navigation delivery. Although the program is still in early phases, it has improved care coordination for Veterans with breast and gynecologic cancers across the United States.

A Phase II Study With Androgen Deprivation Therapy and Up-Front Radiotherapy in High-Intermediate and High-Risk Prostate Cancer With Stereotactic Body Radiation Therapy to Pelvic Nodes and Concomitant Prostate Boost by Simultaneous Integrated Boost
Background
The adoption of Stereotactic Body Radiation Therapy (SBRT) for prostate cancer has allowed treatment to be completed in less than 2 weeks, but has predominantly been given to the prostate only. Currently, very few prospective studies have compared delivery of SBRT versus hypofractionated radiotherapy (HFX) when giving concurrent pelvic radiation. The aim of the study is to evaluate the tolerance and efficacy of pelvic node radiotherapy and SIB to the prostate in prostate patients requiring nodal irradiation.
Methods
A total of 58 patients were irradiated with SBRT and initiated ADT therapy between 2014 and 2023. 57 patients were treated with 7.5 Gy to the prostate and 1 to 7.25 Gy. All patients were treated with 5 Gy x 5 fraction to the pelvis. This group was compared to a preselected historical cohort of 65 HFX patients with 57 of these patients treated with 67.5/50 Gy in 25 fractions, 1 with patient 67.5/45 Gy in 25 fractions, and 6 patients with 60/44-46 Gy in 20 fractions. Patients were evaluated for GU and GI toxicities according to Radiation Therapy Oncology Group Toxicity criteria at one year post radiation therapy.
Results
There were 31 grade 0 (53.4%), 1 grade 1 (1.7%), 25 grade 2 (43.1%), 1 grade 3 (1.7%) events in the SBRT group and 29 GU grade 0 (44.6%), 3 grade 1 (4.6%), and 33 grade 2 (50.8%) GU toxicities in the HFX group with no significant difference between the groups (p=0.464). There were 55 grade 0 (94.8%), 1 grade 1 (1.7%), and 2 grade 2 (3.4%) GI toxicities in the SBRT group and 59 grade 0 (90.8%), 1 grade 1 (1.5%), and 5 grade 2 (7.7%) events in the HFX group with no significant difference between the groups (p=0.381).
Conclusions
This prospective study provides data to support the use of concurrent pelvic radiation with SBRT to the prostate. Our findings suggest there is no difference in toxicity between HFX and 25 Gy pelvic radiation (5 Gy/5 fractions) concurrent with SBRT to the prostate, therefore it appears to be a safe and convenient option for veterans with prostate cancer.

Do Clonal Hematopoiesis and Mosaic Chromosomal Alterations Increase Solid Tumor Risk?
Clonal hematopoiesis of indeterminate potential (CHIP) and mosaic chromosomal alterations (mCAs) are associated with an increased risk for breast cancer, and CHIP is associated with increased mortality in patients with colon cancer, according to the authors of new research.
These findings, drawn from almost 11,000 patients in the Women’s Health Initiative (WHI) study, add further evidence that CHIP and mCA drive solid tumor risk, alongside known associations with hematologic malignancies, reported lead author Pinkal Desai, MD, associate professor of medicine and clinical director of molecular aging at Englander Institute for Precision Medicine, Weill Cornell Medical College, New York City, and colleagues.
How This Study Differs From Others of Breast Cancer Risk Factors
“The independent effect of CHIP and mCA on risk and mortality from solid tumors has not been elucidated due to lack of detailed data on mortality outcomes and risk factors,” the investigators wrote in Cancer, although some previous studies have suggested a link.
In particular, the investigators highlighted a 2022 UK Biobank study, which reported an association between CHIP and lung cancer and a borderline association with breast cancer that did not quite reach statistical significance.
But the UK Biobank study was confined to a UK population, Dr. Desai noted in an interview, and the data were less detailed than those in the present investigation.
“In terms of risk, the part that was lacking in previous studies was a comprehensive assessment of risk factors that increase risk for all these cancers,” Dr. Desai said. “For example, for breast cancer, we had very detailed data on [participants’] Gail risk score, which is known to impact breast cancer risk. We also had mammogram data and colonoscopy data.”
In an accompanying editorial, Koichi Takahashi, MD, PhD , and Nehali Shah, BS, of The University of Texas MD Anderson Cancer Center, Houston, Texas, pointed out the same UK Biobank findings, then noted that CHIP has also been linked with worse overall survival in unselected cancer patients. Still, they wrote, “the impact of CH on cancer risk and mortality remains controversial due to conflicting data and context‐dependent effects,” necessitating studies like this one by Dr. Desai and colleagues.
How Was the Relationship Between CHIP, MCA, and Solid Tumor Risk Assessed?
To explore possible associations between CHIP, mCA, and solid tumors, the investigators analyzed whole genome sequencing data from 10,866 women in the WHI, a multi-study program that began in 1992 and involved 161,808 women in both observational and clinical trial cohorts.
In 2002, the first big data release from the WHI suggested that hormone replacement therapy (HRT) increased breast cancer risk, leading to widespread reduction in HRT use.
More recent reports continue to shape our understanding of these risks, suggesting differences across cancer types. For breast cancer, the WHI data suggested that HRT-associated risk was largely driven by formulations involving progesterone and estrogen, whereas estrogen-only formulations, now more common, are generally considered to present an acceptable risk profile for suitable patients.
The new study accounted for this potential HRT-associated risk, including by adjusting for patients who received HRT, type of HRT received, and duration of HRT received. According to Desai, this approach is commonly used when analyzing data from the WHI, nullifying concerns about the potentially deleterious effects of the hormones used in the study.
“Our question was not ‘does HRT cause cancer?’ ” Dr. Desai said in an interview. “But HRT can be linked to breast cancer risk and has a potential to be a confounder, and hence the above methodology.
“So I can say that the confounding/effect modification that HRT would have contributed to in the relationship between exposure (CH and mCA) and outcome (cancer) is well adjusted for as described above. This is standard in WHI analyses,” she continued.
“Every Women’s Health Initiative analysis that comes out — not just for our study — uses a standard method ... where you account for hormonal therapy,” Dr. Desai added, again noting that many other potential risk factors were considered, enabling a “detailed, robust” analysis.
Dr. Takahashi and Ms. Shah agreed. “A notable strength of this study is its adjustment for many confounding factors,” they wrote. “The cohort’s well‐annotated data on other known cancer risk factors allowed for a robust assessment of CH’s independent risk.”
How Do Findings Compare With Those of the UK Biobank Study?
CHIP was associated with a 30% increased risk for breast cancer (hazard ratio [HR], 1.30; 95% CI, 1.03-1.64; P = .02), strengthening the borderline association reported by the UK Biobank study.
In contrast with the UK Biobank study, CHIP was not associated with lung cancer risk, although this may have been caused by fewer cases of lung cancer and a lack of male patients, Dr. Desai suggested.
“The discrepancy between the studies lies in the risk of lung cancer, although the point estimate in the current study suggested a positive association,” wrote Dr. Takahashi and Ms. Shah.
As in the UK Biobank study, CHIP was not associated with increased risk of developing colorectal cancer.
Mortality analysis, however, which was not conducted in the UK Biobank study, offered a new insight: Patients with existing colorectal cancer and CHIP had a significantly higher mortality risk than those without CHIP. Before stage adjustment, risk for mortality among those with colorectal cancer and CHIP was fourfold higher than those without CHIP (HR, 3.99; 95% CI, 2.41-6.62; P < .001). After stage adjustment, CHIP was still associated with a twofold higher mortality risk (HR, 2.50; 95% CI, 1.32-4.72; P = .004).
The investigators’ first mCA analyses, which employed a cell fraction cutoff greater than 3%, were unfruitful. But raising the cell fraction threshold to 5% in an exploratory analysis showed that autosomal mCA was associated with a 39% increased risk for breast cancer (HR, 1.39; 95% CI, 1.06-1.83; P = .01). No such associations were found between mCA and colorectal or lung cancer, regardless of cell fraction threshold.
The original 3% cell fraction threshold was selected on the basis of previous studies reporting a link between mCA and hematologic malignancies at this cutoff, Dr. Desai said.
She and her colleagues said a higher 5% cutoff might be needed, as they suspected that the link between mCA and solid tumors may not be causal, requiring a higher mutation rate.
Why Do Results Differ Between These Types of Studies?
Dr. Takahashi and Ms. Shah suggested that one possible limitation of the new study, and an obstacle to comparing results with the UK Biobank study and others like it, goes beyond population heterogeneity; incongruent findings could also be explained by differences in whole genome sequencing (WGS) technique.
“Although WGS allows sensitive detection of mCA through broad genomic coverage, it is less effective at detecting CHIP with low variant allele frequency (VAF) due to its relatively shallow depth (30x),” they wrote. “Consequently, the prevalence of mCA (18.8%) was much higher than that of CHIP (8.3%) in this cohort, contrasting with other studies using deeper sequencing.” As a result, the present study may have underestimated CHIP prevalence because of shallow sequencing depth.
“This inconsistency is a common challenge in CH population studies due to the lack of standardized methodologies and the frequent reliance on preexisting data not originally intended for CH detection,” Dr. Takahashi and Ms. Shah said.
Even so, despite the “heavily context-dependent” nature of these reported risks, the body of evidence to date now offers a convincing biological rationale linking CH with cancer development and outcomes, they added.
How Do the CHIP- and mCA-associated Risks Differ Between Solid Tumors and Blood Cancers?
“[These solid tumor risks are] not causal in the way CHIP mutations are causal for blood cancers,” Dr. Desai said. “Here we are talking about solid tumor risk, and it’s kind of scattered. It’s not just breast cancer ... there’s also increased colon cancer mortality. So I feel these mutations are doing something different ... they are sort of an added factor.”
Specific mechanisms remain unclear, Dr. Desai said, although she speculated about possible impacts on the inflammatory state or alterations to the tumor microenvironment.
“These are blood cells, right?” Dr. Desai asked. “They’re everywhere, and they’re changing something inherently in these tumors.”
Future research and therapeutic development
Siddhartha Jaiswal, MD, PhD, assistant professor in the Department of Pathology at Stanford University in California, whose lab focuses on clonal hematopoiesis, said the causality question is central to future research.
“The key question is, are these mutations acting because they alter the function of blood cells in some way to promote cancer risk, or is it reflective of some sort of shared etiology that’s not causal?” Dr. Jaiswal said in an interview.
Available data support both possibilities.
On one side, “reasonable evidence” supports the noncausal view, Dr. Jaiswal noted, because telomere length is one of the most common genetic risk factors for clonal hematopoiesis and also for solid tumors, suggesting a shared genetic factor. On the other hand, CHIP and mCA could be directly protumorigenic via conferred disturbances of immune cell function.
When asked if both causal and noncausal factors could be at play, Dr. Jaiswal said, “yeah, absolutely.”
The presence of a causal association could be promising from a therapeutic standpoint.
“If it turns out that this association is driven by a direct causal effect of the mutations, perhaps related to immune cell function or dysfunction, then targeting that dysfunction could be a therapeutic path to improve outcomes in people, and there’s a lot of interest in this,” Dr. Jaiswal said. He went on to explain how a trial exploring this approach via interleukin-8 inhibition in lung cancer fell short.
Yet earlier intervention may still hold promise, according to experts.
“[This study] provokes the hypothesis that CH‐targeted interventions could potentially reduce cancer risk in the future,” Dr. Takahashi and Ms. Shah said in their editorial.
The WHI program is funded by the National Heart, Lung, and Blood Institute; National Institutes of Health; and the Department of Health & Human Services. The investigators disclosed relationships with Eli Lilly, AbbVie, Celgene, and others. Dr. Jaiswal reported stock equity in a company that has an interest in clonal hematopoiesis.

“Our question was not ‘does HRT cause cancer?’ ” Dr. Desai said in an interview. “But HRT can be linked to breast cancer risk and has a potential to be a confounder, and hence the above methodology.
“So I can say that the confounding/effect modification that HRT would have contributed to in the relationship between exposure (CH and mCA) and outcome (cancer) is well adjusted for as described above. This is standard in WHI analyses,” she continued.
“Every Women’s Health Initiative analysis that comes out — not just for our study — uses a standard method ... where you account for hormonal therapy,” Dr. Desai added, again noting that many other potential risk factors were considered, enabling a “detailed, robust” analysis.
Dr. Takahashi and Ms. Shah agreed. “A notable strength of this study is its adjustment for many confounding factors,” they wrote. “The cohort’s well‐annotated data on other known cancer risk factors allowed for a robust assessment of CH’s independent risk.”
How Do Findings Compare With Those of the UK Biobank Study?
CHIP was associated with a 30% increased risk for breast cancer (hazard ratio [HR], 1.30; 95% CI, 1.03-1.64; P = .02), strengthening the borderline association reported by the UK Biobank study.
In contrast with the UK Biobank study, CHIP was not associated with lung cancer risk, although this may have been caused by fewer cases of lung cancer and a lack of male patients, Dr. Desai suggested.
“The discrepancy between the studies lies in the risk of lung cancer, although the point estimate in the current study suggested a positive association,” wrote Dr. Takahashi and Ms. Shah.
As in the UK Biobank study, CHIP was not associated with increased risk of developing colorectal cancer.
Mortality analysis, however, which was not conducted in the UK Biobank study, offered a new insight: Patients with existing colorectal cancer and CHIP had a significantly higher mortality risk than those without CHIP. Before stage adjustment, risk for mortality among those with colorectal cancer and CHIP was fourfold higher than those without CHIP (HR, 3.99; 95% CI, 2.41-6.62; P < .001). After stage adjustment, CHIP was still associated with a twofold higher mortality risk (HR, 2.50; 95% CI, 1.32-4.72; P = .004).
The investigators’ first mCA analyses, which employed a cell fraction cutoff greater than 3%, were unfruitful. But raising the cell fraction threshold to 5% in an exploratory analysis showed that autosomal mCA was associated with a 39% increased risk for breast cancer (HR, 1.39; 95% CI, 1.06-1.83; P = .01). No such associations were found between mCA and colorectal or lung cancer, regardless of cell fraction threshold.
The original 3% cell fraction threshold was selected on the basis of previous studies reporting a link between mCA and hematologic malignancies at this cutoff, Dr. Desai said.
She and her colleagues said a higher 5% cutoff might be needed, as they suspected that the link between mCA and solid tumors may not be causal, requiring a higher mutation rate.
Why Do Results Differ Between These Types of Studies?
Dr. Takahashi and Ms. Shah suggested that one possible limitation of the new study, and an obstacle to comparing results with the UK Biobank study and others like it, goes beyond population heterogeneity; incongruent findings could also be explained by differences in whole genome sequencing (WGS) technique.
“Although WGS allows sensitive detection of mCA through broad genomic coverage, it is less effective at detecting CHIP with low variant allele frequency (VAF) due to its relatively shallow depth (30x),” they wrote. “Consequently, the prevalence of mCA (18.8%) was much higher than that of CHIP (8.3%) in this cohort, contrasting with other studies using deeper sequencing.” As a result, the present study may have underestimated CHIP prevalence because of shallow sequencing depth.
“This inconsistency is a common challenge in CH population studies due to the lack of standardized methodologies and the frequent reliance on preexisting data not originally intended for CH detection,” Dr. Takahashi and Ms. Shah said.
Even so, despite the “heavily context-dependent” nature of these reported risks, the body of evidence to date now offers a convincing biological rationale linking CH with cancer development and outcomes, they added.
How Do the CHIP- and mCA-associated Risks Differ Between Solid Tumors and Blood Cancers?
“[These solid tumor risks are] not causal in the way CHIP mutations are causal for blood cancers,” Dr. Desai said. “Here we are talking about solid tumor risk, and it’s kind of scattered. It’s not just breast cancer ... there’s also increased colon cancer mortality. So I feel these mutations are doing something different ... they are sort of an added factor.”
Specific mechanisms remain unclear, Dr. Desai said, although she speculated about possible impacts on the inflammatory state or alterations to the tumor microenvironment.
“These are blood cells, right?” Dr. Desai asked. “They’re everywhere, and they’re changing something inherently in these tumors.”
Future research and therapeutic development
Siddhartha Jaiswal, MD, PhD, assistant professor in the Department of Pathology at Stanford University in California, whose lab focuses on clonal hematopoiesis, said the causality question is central to future research.
“The key question is, are these mutations acting because they alter the function of blood cells in some way to promote cancer risk, or is it reflective of some sort of shared etiology that’s not causal?” Dr. Jaiswal said in an interview.
Available data support both possibilities.
On one side, “reasonable evidence” supports the noncausal view, Dr. Jaiswal noted, because telomere length is one of the most common genetic risk factors for clonal hematopoiesis and also for solid tumors, suggesting a shared genetic factor. On the other hand, CHIP and mCA could be directly protumorigenic via conferred disturbances of immune cell function.
When asked if both causal and noncausal factors could be at play, Dr. Jaiswal said, “yeah, absolutely.”
The presence of a causal association could be promising from a therapeutic standpoint.
“If it turns out that this association is driven by a direct causal effect of the mutations, perhaps related to immune cell function or dysfunction, then targeting that dysfunction could be a therapeutic path to improve outcomes in people, and there’s a lot of interest in this,” Dr. Jaiswal said. He went on to explain how a trial exploring this approach via interleukin-8 inhibition in lung cancer fell short.
Yet earlier intervention may still hold promise, according to experts.
“[This study] provokes the hypothesis that CH‐targeted interventions could potentially reduce cancer risk in the future,” Dr. Takahashi and Ms. Shah said in their editorial.
The WHI program is funded by the National Heart, Lung, and Blood Institute; National Institutes of Health; and the Department of Health & Human Services. The investigators disclosed relationships with Eli Lilly, AbbVie, Celgene, and others. Dr. Jaiswal reported stock equity in a company that has an interest in clonal hematopoiesis.

Clonal hematopoiesis of indeterminate potential (CHIP) and mosaic chromosomal alterations (mCAs) are associated with an increased risk for breast cancer, and CHIP is associated with increased mortality in patients with colon cancer, according to the authors of new research.
These findings, drawn from almost 11,000 patients in the Women’s Health Initiative (WHI) study, add further evidence that CHIP and mCA drive solid tumor risk, alongside known associations with hematologic malignancies, reported lead author Pinkal Desai, MD, associate professor of medicine and clinical director of molecular aging at Englander Institute for Precision Medicine, Weill Cornell Medical College, New York City, and colleagues.
How This Study Differs From Others of Breast Cancer Risk Factors
“The independent effect of CHIP and mCA on risk and mortality from solid tumors has not been elucidated due to lack of detailed data on mortality outcomes and risk factors,” the investigators wrote in Cancer, although some previous studies have suggested a link.
In particular, the investigators highlighted a 2022 UK Biobank study, which reported an association between CHIP and lung cancer and a borderline association with breast cancer that did not quite reach statistical significance.
But the UK Biobank study was confined to a UK population, Dr. Desai noted in an interview, and the data were less detailed than those in the present investigation.
“In terms of risk, the part that was lacking in previous studies was a comprehensive assessment of risk factors that increase risk for all these cancers,” Dr. Desai said. “For example, for breast cancer, we had very detailed data on [participants’] Gail risk score, which is known to impact breast cancer risk. We also had mammogram data and colonoscopy data.”
In an accompanying editorial, Koichi Takahashi, MD, PhD , and Nehali Shah, BS, of The University of Texas MD Anderson Cancer Center, Houston, Texas, pointed out the same UK Biobank findings, then noted that CHIP has also been linked with worse overall survival in unselected cancer patients. Still, they wrote, “the impact of CH on cancer risk and mortality remains controversial due to conflicting data and context‐dependent effects,” necessitating studies like this one by Dr. Desai and colleagues.
How Was the Relationship Between CHIP, MCA, and Solid Tumor Risk Assessed?
To explore possible associations between CHIP, mCA, and solid tumors, the investigators analyzed whole genome sequencing data from 10,866 women in the WHI, a multi-study program that began in 1992 and involved 161,808 women in both observational and clinical trial cohorts.
In 2002, the first big data release from the WHI suggested that hormone replacement therapy (HRT) increased breast cancer risk, leading to widespread reduction in HRT use.
More recent reports continue to shape our understanding of these risks, suggesting differences across cancer types. For breast cancer, the WHI data suggested that HRT-associated risk was largely driven by formulations involving progesterone and estrogen, whereas estrogen-only formulations, now more common, are generally considered to present an acceptable risk profile for suitable patients.
The new study accounted for this potential HRT-associated risk, including by adjusting for patients who received HRT, type of HRT received, and duration of HRT received. According to Desai, this approach is commonly used when analyzing data from the WHI, nullifying concerns about the potentially deleterious effects of the hormones used in the study.
“Our question was not ‘does HRT cause cancer?’ ” Dr. Desai said in an interview. “But HRT can be linked to breast cancer risk and has a potential to be a confounder, and hence the above methodology.

Identifying Barriers in Germline Genetic Testing Referrals for Breast Cancer: A Single-Center Experience
Background
Purpose: to review the number of genetic testing referrals for breast cancer at the Stratton VA Medical Center and identify barriers that hinder testing, aiming to improve risk reduction strategies and therapeutic options for patients. National guidelines recommend genetic testing for breast cancer susceptibility genes in specific patient populations, such as those under 50, those with a high-risk family history, high-risk pathology, male breast cancer, or Ashkenazi Jewish ancestry. Despite efforts to adhere to these guidelines, several barriers persist that limit testing rates among eligible patients.
Methods
The medical oncology team selected breast cancer as the focus for reviewing adherence to germline genetic testing referrals in the Stratton VA Medical Center. With assistance from cancer registrars, a list of genetics referrals for breast cancer from January to December 2023 was compiled. Descriptive analysis was conducted to assess referral rates, evaluation visit completion rates, genetic testing outcomes, and reasons for non-completion of genetic testing.
Results
During the study period, 32 patients were referred for germline genetic testing for breast cancer. Of these, 26 (81%) completed the evaluation visit, and 11 (34%) underwent genetic testing. Of these, 7 patients had noteworthy results, and 2 patients (6%) were found to carry pathogenic variants: BRCA2 and CDH1. Reasons for non-completion included perceived irrelevance without biological children, need for additional time to consider testing, fear of exacerbating self-harm thoughts, and fear of losing service connection. Additionally, 2 patients did not meet the guidelines for testing per genetic counselor.
Conclusions
This project marks the initial step in identifying barriers to germline genetic testing for breast cancer based on an extensive review of patients diagnosed and treated at a single VA site. Despite the removal of the service connection clause from the consent form, some veterans still declined testing due to fear of losing their service connection. The findings emphasize the importance of educating providers on counseling techniques and education of veterans to enhance risk reduction strategies and patient care. Further research is essential to quantify the real-world outcomes and longterm impacts of improving genetic counseling rates on patient management and outcomes.

Do We Need More Screen Time? Patterns of Telehealth Utilization for Patients With Prostate Cancer in the Veterans Health Administration (VHA)
Background
Prostate cancer is the most common cancer in the VHA. Telehealth use has increased and has the potential to improve access for patients. We examined patterns of care for VHA patients with prostate cancer, including whether visits were in person, by telephone or by video.
Methods
Using the VHA Corporate Data Warehouse, we extracted data on all incident cases of prostate cancer from 1/1/2016-1/31/2023 with sufficient information (Gleason score, prostate-specific antigen [PSA], and tumor stage) to categorize into National Comprehensive Cancer Network (NCCN) risk strata. We excluded patients who died within 1 year of diagnosis and those with no evidence of PSA testing, prostate biopsy or treatment within 2 years. We categorized all outpatient visits related to a person’s Urology- and Medical Oncology based care – including the visit modality – based on administrative visit stop codes. We defined ‘during COVID’ as visits after 3/11/2020. We calculated the percent of visits performed by modality in each year after diagnosis.
Results
Among the 60,381 men with prostate cancer, 61% were White, 33% Black; 5% Hispanic; 32% rural. For NCCN category, 30% had high risk prostate cancer, which increased with age, 50% had intermediate risk and 20% had low risk. Prior to COVID, for visits to Urology within the first year after diagnosis, 79% were in person, 20% were by telephone and 0.1% were by video. Visits to Oncology within the first year after diagnosis were similar—82% in person, 16% by phone and 0.3% by video.
Discussion
During the COVID period, video visits increased significantly but remained a small proportion, accounting for only 2% of visits for both Urology and Oncology. Video visits increased during the COVID-19 pandemic but remained rare. Across many diseases and conditions, the quality of care for video visits has been at least as good as for in-person care.
Conclusions
There is a missed opportunity to provide care by video within VHA for patients with prostate cancer, particularly given that about 1/3 of patients are from rural areas. Future analyses will examine barriers to video telehealth and the impact of video visits on quality and equity of prostate cancer care.

Asynchronous Bilateral Breast Cancer in a Male Patient
Background
Bilateral male breast cancer remains a rare occurrence with limited representation in published literature. Here we present a case of an 82-yearold male with asynchronous bilateral breast cancer.
Case Presentation
Our patient is an 82-year-old male past smoker initially diagnosed with left T1aN0M0 invasive lobular carcinoma in 2010 that was ER, PR positive and HER2 negative. He underwent a left mastectomy with sentinel node biopsy and was given tamoxifen therapy for 10 years. In 2020, the patient was also diagnosed with lung squamous cell carcinoma and was treated with stereotactic body radiotherapy. In September 2023, he started noticing discharge from his right nipple. A PET CT scan revealed hyper-metabolic activity in the bilateral upper lung lobes and slightly increased activity in the right breast. A biopsy of the left upper lobe showed atypical cells. He also underwent a right breast mastectomy and sentinel lymph node biopsy which showed grade 1-2 ductal carcinoma in situ and negative sentinel lymph nodes. The tumor board recommended no further treatment after his mastectomy and genetic testing which is currently pending.
Discussion
Male breast cancer comprises just 1% of breast cancer cases, with asynchronous bilateral occurrences being exceedingly rare. A review of PubMed literature yielded only 2 documented case reports. Male breast cancer usually diagnosed around ages 60 to 70 years. The predominant histopathological diagnosis is invasive ductal adenocarcinoma that more frequently expresses ER/PR over HER2. It often manifests as a painless lump, frequently diagnosed at an advanced stage, possibly due to factors such as lower screening rates in males and less breast parenchyma. Local treatment options include surgery and radiotherapy. Neoadjuvant tamoxifen therapy is appropriate for ER and PR expressing cancers and chemotherapy can be used for non-hormone expressing or metastatic tumors. Given its rarity, management and diagnostic strategies for male breast cancer are often adapted from research on female breast cancer
Conclusions
Our case is of a relatively uncommon incident of asynchronous bilateral male breast cancer, emphasizing the need for expanded research efforts in male breast cancer. An enhanced understanding could lead to improved diagnosis and management strategies, potentially enhancing survival outcomes.

Our patient is an 82-year-old male past smoker initially diagnosed with left T1aN0M0 invasive lobular carcinoma in 2010 that was ER, PR positive and HER2 negative. He underwent a left mastectomy with sentinel node biopsy and was given tamoxifen therapy for 10 years. In 2020, the patient was also diagnosed with lung squamous cell carcinoma and was treated with stereotactic body radiotherapy. In September 2023, he started noticing discharge from his right nipple. A PET CT scan revealed hyper-metabolic activity in the bilateral upper lung lobes and slightly increased activity in the right breast. A biopsy of the left upper lobe showed atypical cells. He also underwent a right breast mastectomy and sentinel lymph node biopsy which showed grade 1-2 ductal carcinoma in situ and negative sentinel lymph nodes. The tumor board recommended no further treatment after his mastectomy and genetic testing which is currently pending.
Discussion
Male breast cancer comprises just 1% of breast cancer cases, with asynchronous bilateral occurrences being exceedingly rare. A review of PubMed literature yielded only 2 documented case reports. Male breast cancer usually diagnosed around ages 60 to 70 years. The predominant histopathological diagnosis is invasive ductal adenocarcinoma that more frequently expresses ER/PR over HER2. It often manifests as a painless lump, frequently diagnosed at an advanced stage, possibly due to factors such as lower screening rates in males and less breast parenchyma. Local treatment options include surgery and radiotherapy. Neoadjuvant tamoxifen therapy is appropriate for ER and PR expressing cancers and chemotherapy can be used for non-hormone expressing or metastatic tumors. Given its rarity, management and diagnostic strategies for male breast cancer are often adapted from research on female breast cancer
Conclusions
Our case is of a relatively uncommon incident of asynchronous bilateral male breast cancer, emphasizing the need for expanded research efforts in male breast cancer. An enhanced understanding could lead to improved diagnosis and management strategies, potentially enhancing survival outcomes.
Metastatic Prostate Cancer Presenting as Pleural and Pericardial Metastases: A Case Report and Literature Review
Background
Metastatic prostate cancer typically manifests with metastases to the lungs, bones, and adrenal glands. Here, we report a unique case where the initial presentation involved pleural nodules, subsequently leading to the discovery of pleural and pericardial metastases.
Case Presentation
Our patient, a 73-year-old male with a history of active tobacco use disorder, COPD, and right shoulder melanoma (2004), initially presented to his primary care physician for a routine visit. Following a Low Dose Chest CT scan (LDCT), numerous new pleural nodules were identified. Physical examination revealed small nevi and skin tags, but no malignant characteristics. Initial concerns centered on the potential recurrence of malignant melanoma with pleural metastases or an inflammatory condition. Subsequent PET scan results raised significant suspicion of malignancy. PSA was 2.41. Pleuroscopy biopsies revealed invasive nonsmall cell carcinoma, positive for NKX31 and MOC31, but negative for S100, PSA, and synaptophysin. This pattern strongly suggests metastatic prostate cancer despite the absence of PSA staining. (Stage IV B: cTxcN1cM1c). A subsequent PSMA PET highlighted extensive metastatic involvement in the pericardium, posterior and mediastinal pleura, mediastinum, and ribs. Treatment commenced with Degarelix followed by the standard regimen of Docetaxel, Abiraterone, and prednisone. Genetic counseling and palliative care services were additionally recommended.
Discussion
Prostate cancer typically spreads to bones, lungs, liver, and adrenal glands. Rarely, it appears in sites like pericardium and pleura. Pleural metastases are usually found postmortem; clinical diagnosis is rare. Pericardial metastases are exceptionally uncommon, with few documented cases. The precise mechanism of metastatic dissemination remains uncertain, with theories suggesting spread through the vertebral-venous plexus or via the vena cava to distant organs. Treatment approaches vary based on symptomatic effusions, ranging from pericardiocentesis, thoracocentesis to chemotherapy, radiotherapy, and hormone therapy. Studies have shown systemic docetaxel to be effective in managing pleural and pericardial symptoms. Despite their rarity, healthcare providers should consider these possibilities when encountering pleural thickening or pericardial abnormalities on imaging studies.
Conclusions
Pleural and pericardial metastases represent uncommon occurrences in prostate cancer. Continued research efforts can facilitate early detection of metastatic disease, enabling more effective and precisely targeted management strategies when symptoms manifest.

Olanzapine Eases Chemo-Induced Nausea and Vomiting
TOPLINE:
, reduced need for rescue medications, and improved quality of life in patients with solid malignant tumors at moderate risk for chemotherapy-induced nausea and vomiting, a new analysis finds.
METHODOLOGY:
- Chemotherapy-induced nausea and vomiting can impact quality of life in patients with cancer. Olanzapine — an atypical antipsychotic agent — has been approved as part of antiemetic prophylaxis in patients receiving chemotherapy regimens that come with a high risk for nausea and vomiting; the agent may also help those at more moderate risk for chemotherapy-induced nausea and vomiting.
- Researchers evaluated whether receiving antiemetic prophylaxis with olanzapine reduced nausea and vomiting and improved complete response rates in patients at more moderate risk for chemotherapy-induced nausea and vomiting.
- In the phase 3 randomized study, 544 patients (median age, 51 years) with solid malignant tumors received either oxaliplatin-, irinotecan-, or carboplatin-based chemotherapy regimens at three institutes in India and were randomly assigned to antiemetic prophylaxis that included dexamethasone, aprepitant, and palonosetron with or without 10 mg olanzapine.
- The primary endpoint was the rate of complete response — defined as no vomiting, a nausea score < 5 on the visual analog scale, and no use of rescue medications during the first 120 hours of chemotherapy. Secondary endpoints included the proportion of patients who experienced nausea or chemotherapy-induced nausea and vomiting and who received rescue medications.
TAKEAWAY:
- Overall, patients who received olanzapine had a significantly higher complete response rate (91%) than those not receiving olanzapine (82%). This effect was significant after 25 hours (92% vs 83%; P = .001) but not within the first 24 hours of the chemotherapy cycle (96% vs 94%; P = .53).
- The addition of olanzapine improved complete response rates in patients who received oxaliplatin-based chemotherapy (odds ratio [OR], 0.36) and carboplatin-based chemotherapy (OR, 0.23) but not irinotecan-based chemotherapy (OR, 2.36; 95% CI, 0.23-24.25).
- Olanzapine led to better nausea control, with 96% of patients achieving a nausea score < 5 on the visual analog scale compared with 87% in the observation group (P < .001) as well as eased chemotherapy-induced nausea and vomiting (96% vs 91%; P = .02). Olanzapine also reduced the need for rescue medications — only 4% of patients in the olanzapine group received rescue medications vs 11% of patients not receiving olanzapine — and improved patients’ quality of life.
- However, 10% of the patients in the olanzapine group experienced grade 1 somnolence, whereas none in the observation group reported this side effect.
IN PRACTICE:
“Olanzapine 10 mg, combined with aprepitant, palonosetron, and dexamethasone, improved complete response rates compared with no olanzapine,” the authors concluded. “These findings suggest that this regimen could be considered as one of the standards of antiemetic therapy” in patients receiving chemotherapy regimens associated with a moderate risk for chemotherapy-induced nausea and vomiting.
SOURCE:
The study, led by Vikas Ostwal, DM, Tata Memorial Centre, Mumbai, India, was published online in JAMA Network Open.
LIMITATIONS:
The lack of a placebo group could affect the interpretation of the results. The study evaluated only a 10-mg dose of olanzapine but did not consider a lower (5-mg) dose. Other potential side effects of olanzapine, such as increased appetite or constipation, were not reported. The study predominantly involved patients with gastrointestinal cancers receiving oxaliplatin-containing regimens, which may limit the generalizability of the findings.
DISCLOSURES:
The study was supported by grants from Intas Pharmaceuticals, Zydus Lifesciences, and Dr. Reddy’s Laboratories to Tata Memorial Centre. Several authors reported receiving grants and having other ties with various sources.

Beyond Borders: Tonsillar Squamous Cell Carcinoma with Intriguing Liver Metastasis
Background
Oropharyngeal squamous cell carcinoma (OPSCC) arises in the middle pharynx, including the tonsils, base of the tongue, and surrounding tissues. While OPSCC commonly metastasizes to regional lymph nodes, distant metastases to sites like the liver are rare, occurring in about 1-4% of cases with advanced disease.
Case Presentation
A 66-year-old male presented to the emergency department with recurrent right-sided facial swelling and a two-week history of sore throat. CT imaging revealed a large right tonsillar mass extending to the base of the tongue. Further evaluation with PET scan showed hypermetabolic activity in the right tonsil, multiple hypermetabolic lymph nodes in the right neck (stations 1B, 2, 3, 4, 5), right supraclavicular fossa, and small retropharyngeal nodes. Additionally, PET scan detected a hypermetabolic lesion in the liver and focal activity at T10 suggestive of bone metastasis. Fine needle aspiration (FNA) confirmed squamous cell carcinoma. Biopsy of the liver lesion revealed metastatic squamous cell carcinoma with basaloid differentiation, positive for p40 and p63 stains. Clinical staging was T2b cN2 cM1. The patient’s case was discussed in tumor boards, leading to a treatment plan of palliative radiotherapy with radiosensitizer (weekly carboplatin/paclitaxel) due to recent myocardial infarction, precluding cisplatin or 5FU use. Post-radiotherapy, Pembrolizumab was planned based on 60% PD-L1 expression. The patient opted to forego additional systemic chemotherapy and currently receives Keytruda every three weeks.
Discussion
Liver metastases from head and neck SCC are rare, highlighting the complexity of treatment decisions in such cases. Effective management requires a multidisciplinary approach to optimize therapeutic outcomes while considering patient-specific factors and comorbidities.
Conclusions
This case underscores the challenges and poor prognosis associated with tonsillar SCC with liver metastases. It underscores the need for personalized treatment strategies tailored to the unique characteristics of each patient’s disease.
