- Title: A Phase III Study of the Treatment of Pathologic Stage C Carcinoma of the Prostate With Adjuvant Radiotherapy
- (1) To compare the disease-free survival rates in completely resected patients with pathologic stage C (T3N0M0) carcinoma of the prostate assigned to be treated with adjuvant external beam radiotherapy to that in patients assigned to receive no adjuvant therapy
- (2) To assess the qualitative and quantitative toxicities of patients with pathologic stage C (T3N0M0) carcinoma of the prostate when treated with external beam radiotherapy.
- Arm 1: Radical Prostatectomy
- Arm 2: Radical Prostatectomy + 60-64 Gy EBRT
- Eligibility: Status Post RP, +ECE or +SVI or +SM, N0M0
- Activation: August 15, 1988 (RTOG Activation: April 20, 1992)
- Closed: January 1, 1997
- 2007 PMID 17538167 -- "Predominant treatment failure in postprostatectomy patients is local: analysis of patterns of treatment failure in SWOG 8794." (Swanson GP, J Clin Oncol. 2007 Jun 1;25(16):2225-9.) Conclusion: Failure in high risk patients predominately local; adjuvant RT reduces risk of failure

Conclusion: Adjuvant radiotherapy resulted in significantly reduced risk of PSA relapse and disease recurrence, although the improvements in metastasis-free survival and overall survival were not statistically significant.
