A new practice guideline released at the American Urological Association annual meeting presents the clinical framework to help weigh the risks and benefits of providing adjuvant and salvage radiation therapy after prostatectomy.

"There is now a document that guides us in offering the best clinical practices for anyone who undergoes radical prostatectomy regarding their follow-up care with radiotherapy," said Dr. Richard K. Valicenti of the department of radiation oncology at the University of California, Davis.

One practice standard in the guideline advises physicians to offer adjuvant radiotherapy to patients with adverse pathologic findings at prostatectomy, because studies have shown that this therapy can result in reductions in prostate-specific antigen (PSA) recurrence, local recurrence, and clinical progression. The adverse findings that would warrant this therapy include seminal vesicle invasion, positive surgical margins, or extraprostatic extension.

"The data are overwhelmingly consistent that it [radiotherapy] will improve on tumor control rates, as well as progression-free survival," Dr. Valicenti said, adding that these patients should also experience improved quality of life.

In addition to the above practice standard, the guideline, issued jointly by the American Society for Radiation Oncology (ASTRO) and the American Urological Association (AUA), made the following recommendations:

• Inform patients with localized prostate cancer considering radical prostatectomy about the possibility that the pathologic findings will predict a higher risk of cancer recurrence.

• Advise patients with adverse pathologic findings, including seminal vesicle invasion, positive surgical margins, and extraprostatic extension, that adjuvant radiation therapy compared with radical prostatectomy only reduces the risk of PSA recurrence, local recurrence, and clinical progression of cancer;

• Warn patients that they are a higher risk of developing metastatic prostate cancer or death from the disease if there is a PSA recurrence after surgery;

• Define biochemical recurrence as a detectable or rising PSA value after surgery that is greater than or equal to 0.2 ng/mL with a second confirmatory level greater than or equal to 0.2 ng/mL.

• Consider a restaging evaluation in patients with a PSA recurrence.

• Offer salvage radiation therapy to patients with PSA or local recurrence after radical prostatectomy in whom there is no evidence of distant metastatic disease.

• Inform patients that the effectiveness of radiation therapy for PSA recurrence is greatest when given at lower levels of PSA. and

• Inform patients that in addition to the benefits of controlling disease recurrence, radiation therapy could produce possible short- and long-term urinary, bowel, and sexual side effects.

Before recommending adjuvant or salvage radiotherapy, "look at the patients’ biological information obtained from the radical prostatectomy specimen, and balance that with the overall health status of the patients [and] concerns about certain aspects of quality of life, whether it be sexual activity or urinary function. They also need to balance that with any other medical conditions or previous treatments that would preclude the use of radiation therapy," Dr. Valicenti said.

"The Adjuvant and Salvage Radiotherapy After Prostatectomy: ASTRO/AUA Guideline" is a comprehensive review of 324 research articles on patients with detectable and undetectable PSA levels, toxicity, optimal imaging strategies, and the impact on quality of life to determine the appropriateness of radiation therapy in patients suspected of recurrence. Only studies in which PSA data were provided for at least 75% of patients were included in the guideline. The panel was led by Dr. Valicenti and Dr. Ian M. Thompson of the University of Texas Health Science Center.

Dr. Valicenti reported no relevant disclosures.
