Background

Osteosarcoma is an aggressive bone malignancy often treated with surgery. On diagnosis, the majority of patients present with stage II disease. The objective of this study was to compare differences in survival between three commonly used adjuvant therapies: chemotherapy, radiation, and combined chemoradiation therapy in patients presenting with stage II disease.

Methods

The National Cancer Database (NCDB) was used to identify patients diagnosed with osteosarcoma from 2004 to 2018 using the ICD-O-3 histology codes 9180-9187. Patients with stage II disease and who had undergone a surgical procedure at the primary site were identified. Patients were grouped by the receipt of adjuvant chemotherapy, radiation, or chemoradiation. Descriptive statistics and Kaplan-Meier curves were used to measure survival in these patients. One way ANOVA and chi-square analyses were used to evaluate differences among treatment groups. Data were analyzed using SPSS and statistical significance was set at P = .05.

Results

Of 9955 patients in the NCDB diagnosed with osteosarcoma, 4378 (44%) presented with stage II disease. 710 (17.9%) of these surgical patients received additional adjuvant therapy. 66.0% received chemotherapy, 24.4% received radiation, and 9.57% received combined chemoradiation. Adjuvant chemotherapy had the longest median survival time of 91.7 months. Median survival for adjuvant radiotherapy was 48 months and combined chemoradiation was 50.5 months. On log-rank pairwise comparison, the difference in survival between adjuvant chemotherapy and adjuvant chemoradiation was found to be statistically significant. (P < .001). Patients receiving adjuvant chemotherapy were more likely to be younger and have private insurance. (P < .05) Conversely, patients receiving adjuvant radiation were more likely to be older and have Medicare. (P < .05). No significant differences were seen among patient race, sex, income, or Charleson-Deyo comorbidity score.

Conclusions

This study showed that patients with stage II osteosarcoma who receive adjuvant chemotherapy experience improved median survival in comparison to patients who receive adjuvant radiation. This is an important clinical finding, which should guide future treatment. However, further investigation is required to identify patient and treatment specific factors, which are contributing to mortality.

Background

Previous studies have reported that treatment at academic/research facilities is associated with improved survival in cancer patients. The objective of this study was to investigate the impact of treatment facility type on overall survival for patients presenting with osteosarcoma.

Methods

The National Cancer Database (NCDB) was used to identify patients diagnosed with Osteosarcoma from 2004 to 2018. Facility types were identified as assigned by the Commission on Cancer Accreditation program. Data was analyzed using SPSS and statistical significance was set at P = .05.

Results

Of 2085 patients queried, 39.6% were treated at an academic/research program. The stage-adjusted difference in median survival between academic/research and non-academic programs was found to be statistically significant on log-rank comparison (P < .001). At each NCDB analytic stage (stage I-IV), academic/research programs were associated with decreased hazard and improved median survival. A Cox proportional hazards model showed a decreased likelihood of mortality in patients with osteosarcoma who underwent treatment at an academic/research program (HR, 0.882; 95% CI, .802-.969; P = .009). Chi-square testing revealed that patients at academic/research programs were more likely than those at non-academic/research centers to have private insurance, less likely to have Medicare, and more likely to live in counties of > 1 million people. These facilities were also more likely to have undergone Medicaid expansion in 2014. (P < .05). Patients at non-academic/research programs were more likely to have advanced disease (stage III and IV) and higher comorbidity scores. Additionally, they were less likely to receive surgery and/or chemotherapy at the institution in which they were diagnosed. (P < .05).

Conclusions

This study showed that Osteosarcoma patients treated in an academic/research program facility experienced increased survival compared with non-academic/research facilities. Patients at academic/research facilities tend to have less comorbidities, have private insurance, and present with more treatable disease. Despite these favorable prognostic factors, the data suggest an intrinsic benefit to being treated at an academic/research facility.

Background

Hurthle cell carcinoma (HCC), also known as oxyphilic adenocarcinoma, is a rare malignancy characterized by the presence of mitochondrion-rich, eosinophilic epithelial cells known as Hurthle cells. HCC is a variant of follicular thyroid cancer and can metastasize more aggressively than other thyroid malignancies. The purpose of this study is to identify how insurance status impacts median survival time in patients with HCC.

Methods

Using the NCDB, we identified 10,378 patients diagnosed with HCC between 2004 and 2016 using ICD-O-3 histology code 8290. The cohort was analyzed to identify differences in survival outcomes based on the insurance status of the patient during treatment. The 4 categories of insurance identified were uninsured, private insurance, Medicaid, and Medicare. Univariate analysis was performed assessing patient length of survival for each insurance subtype. Data were analyzed using SPSS and statistical significance was set at P = .05.

Results 

We identified statistically significant differences (P < .001) in survival outcomes between privately insured patients and patients with Medicaid or Medicare. Privately insured patients had the highest rates of median survival with 150.9 months, while patients on Medicare had the lowest rates of median survival with 108.1 months. Medicaid and uninsured patients had a median survival rates of 134.5 months and 141.9 months, respectively. 40.8% of privately insured patients presented at stage I, while 20.8% of Medicare patients presented at stage I. Patients with private insurance had the lowest rate of presenting with stage IV disease at 5.0%, which was dramatically different from patients with Medicare that presented with stage IV HCC at a rate of 13.0%.

Conclusions

This study shows the discrepancies of survival in patients with HCC based on insurance coverage. HCC patients with private insurance have significantly longer survival outcomes than patients on Medicaid and Medicare. We hypothesize that privately insured patients are more likely to seek treatment earlier and receive a higher level of care. Privately insured patients were also less likely to present with Stage IV HCC than patients with other insurance statuses. Future directions should analyze how treatment type affects survival outcomes.

Purpose 

To evaluate how various demographic factors impact the stage of cancer at diagnosis.

Background 

Laryngeal squamous cell carcinoma (SCC) is a common cancer with variable clinical presentation. While the probability of cure is high, more advanced tumors are less likely to be cured and more likely to have functional deficits from surgical treatment. Given the worsened prognosis of a later-stage diagnosis, it is important to understand what may contribute to a late presentation.

Method/Analysis

Using the National Cancer Database (NCDB), 73,330 patients were identified between 2004 and 2016 with laryngeal SCC. Early (stage 0 or I) vs late-stage (stage IV) cancers were compared based on demographic variables utilizing descriptive statistics, multivariate, and chi-square analyses on SPSS version 28 with a significance of P < .05.

Results 

Women were 27% more likely to have late-stage SCC than men. Black patients were 44% more likely to have late-stage SCC than White patients. No significant difference was found between Hispanic and non-Hispanic patients. Patients with private insurance, Medicare, or other government insurance were less likely (73%, 74%, and 62%, respectively) to have late-stage SCC compared to patients without insurance. Patients with Medicaid were 12% more likely to present later than the uninsured. Patients making $63,000 or greater were 23% less likely to have late-stage SCC than those making less than $38,000. Patients living in more educated areas (< 7% of adults had no high school degree) were 32% less likely to have late-stage SCC compared to less educated areas (> 21% of adults had no high school degree).

Conclusions/Implications

Patients who are Black, uninsured or on Medicaid, have low-socioeconomic status, and live in less educated areas have less favorable diagnoses than their counterparts. These data demonstrates inequities in health care and may lead to a better understanding of social determinants of health that can be used to advocate for improved access and quality of care.

Study Purpose/Background

Malignant mixed Mullerian tumor (MMMT), known as carcinosarcoma of the uterus, is a rare tumor consisting of malignant epithelial and mesenchymal components. Palliative care (PC) has been shown to enhance quality of life and improve outcomes in patients with advanced or incurable cancer. Patients with MMMT may benefit from PC. The project’s objective is to describe disparities in PC utilization among MMMT patients using the National Cancer Database (NCDB).

Methods/Design

A total of 14,085 patients, diagnosed with MMMT, were identified utilizing the NCDB ICD-O-3 histology code 8950. Demographic factors (race, income, facility type, insurance, geographic location, grade, and Charlson-Deyo comorbidity score) were studied in relation to the receipt of PC using multivariate logistic regression.

Results 

3.10% of the study cohort received PC (437/14085). Participants with a median income of ≥ $63,000 (2.74%) were less likely to receive PC than participants making < $38,000 (3.93%), P = .049. Participants treated at an academic/research program (2.48%) were less likely to receive PC compared to patients treated at a community cancer program (4.44%), P = .023. Those with private insurance (2.50%), were less likely to receive PC than those with no insurance (3.56%), P = .032. Participants who received treatment at a facility located in the South Atlantic (2.25%), East North Central (3.11%), West South Central (2.73%) or Pacific (1.36%), were less likely to receive PC than patients who received treatment at a New England facility (4.42%), P < .001, P = .031, P = .017, and P < .001, respectively. Those with tumors that were undifferentiated, anaplastic (3.52%) were more likely to receive PC than those with well-differentiated tumors (1.01%), P = .040.

Conclusions/Implications

PC is underutilized in patients with private insurance, received treatment at an academic/research program, had well-differentiated tumors, and were in the South Atlantic, East North Central, West South Central, and Pacific regions. By highlighting disparities that exist, our study can aid clinicians in addressing PC underutilization to help provide more comprehensive care for patients.
