However, the prognosis of patients who experienced BCR after adjuvant RT has not been extensively investigated. METHODS The study included 79 consecutive patients treated with RP, pelvic lymph node dissection and adjuvant RT for locally advanced PCa (pT3a/pT3b) and/or positive surgical margins (SM+) between 1988 and 2006 at a single cancer center in Japan. All patients had complete pathological data (including pathological stage and Gleason sum at RP, lymph node and surgical margin status). All patients experienced BCR (defined as two consecutive PSA values>0.2 ng/ml) after adjuvant RT. The Kaplan Meier method explored time to cancer-specific mortality (CSM). Univariable and multivariable Cox regression models tested the association between predictors (namely, pre-operative PSA, pathological Gleason sum and stage, time to BCR) and CSM. RESULTS Mean and median age at BCR were 65 and 65.3 yrs, respectively. Mean and median PSA at surgery were 26 and 14.7 ng/ml, respectively. RP Gleason sum was 6, 7 and 8-10 in 22.4, 37.9 and 39.7% of patients, respectively. Extracapsular extension and seminal vesicle invasion (SVI) were present in 81.5 and 18.5% of patients, respectively. Overall, 52.2% of patients had SM+. At Kaplan Meier analysis, cancer specific survival rates at 5 10 and 15 years after BCR were 96, 96 and 78%, respectively. At univariable analyses, age, PSA, RP Gleason sum, SVI, LNI and time to BCR were significantly associated with higher rates of CSM. At multivariable analyses, after adjusting for age, RP Gleason sum, the presence of LNI represented the independent predictors of CSM. CONCLUSIONS Not all patients experiencing BCR after RP and adjuvant RT have the same survival outcome. In case of failure after adjuvant RT, RP Gleason sum and the presence of LNI at RP were significantly associated with higher rates of CSM. © 2012 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 187Issue 4SApril 2012Page: e598-e599 Advertisement Copyright & Permissions© 2012 by American Urological Association Education and Research, Inc.MetricsAuthor Information Kiyotugu Hoshi Yamagata, Japan More articles by this author Natuho Hayashi Yamagata, Japan More articles by this author Yuuta Kurota Yamagata, Japan More articles by this author Akinori Muto Yamagata, Japan More articles by this author Kenji Numahata Yamagata, Japan More articles by this author Osamu Sugano Yamagata, Japan More articles by this author Senji Hoshi Yamagata, Japan More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ..." @default.
