The Impact

PURPOSE Patients with palpable extraprostatic disease (T3) have a poor prostate-specific antigen (PSA) failure-free (bNED) survival rate after radical prostatectomy (RP) or external-beam radiation therapy (RT). This study was performed to validate or refute the prognostic value of the previously defined calculated prostate cancer volume (cV(Ca)). PATIENTS AND METHODS For patients with clinically localized disease (T1c,2), a Cox regression multivariable analysis was used to assess the ability of the cV(Ca) value to predict time to posttherapy PSA failure following RP or RT. RESULTS The cV(Ca) value was a significant predictor (P < or = .0005) of time to posttherapy PSA failure in both an RP and RT data set independent of the one used to derive the cV(Ca)-based clinical staging system. In both RP- and RT-managed patients, estimates of 3-year bNED survival were not statistically different for patients with either T1c,2 disease and a cV(Ca) greater than 4.0 cm3 (RP, 27%; RT, 18%) or T3 disease (RP, 37%; RT, 34%). Despite pathologic T2 disease, the 3-year estimate of bNED survival was at most 51% in RP-managed patients with T1c,2 disease and cV(Ca) greater than 4.0 cm3. CONCLUSION A cV(Ca) greater than 4.0 cm3 identified patients with T1c.2 disease whose bNED survival was poor after RT or RP despite pathologic T2 disease that suggests the presence of occult micrometastatic disease in many of these patients. Prospective randomized trials to evaluate the impact on survival of adjuvant systemic therapy in these high-risk patients are justified.
