CLINICAL AND PATHOLOGICAL CHARACTERISTICS, AND RECURRENCE RATES OF STAGE T1C VERSUS T2A OR T2B PROSTATE CANCER

Abstract

Clinical and pathological features were similar for stages T1c and T2a, and different from stage T2b cancers. The 5-year recurrence-free survival was similar for T1c and T2a (log rank 0.89, p = 0.34), and higher than that for T2b (log rank 34.5, p <0.0001) cancers. However, controlling for all other prognostic factors on a Cox multivariate model, the risk of cancer recurrence was decreased for T1c compared to T2a and T2b disease. The detection of nonpalpable prostate cancer appears to be advantageous for intermediate-term cancer control.
