A series of 105 patients with surgical Stage C adenocarcinoma of the prostate underwent pelvic lymphadenectomy and radical retropubic prostatectomy and were followed up from one and one-half to fifteen years; 33 (31%) of the 105 had clinical Stage C disease. Of the 105 patients, 92 were at risk for greater than or equal to two years, 42 for greater than or equal to five years, and 12 for greater than or equal to ten years. Survival and disease progression were related to tumor grade (Mayo grades 1 through 4) and tumor bulk (less than 3, 3 to 10, greater than 10 cm3) but not to seminal vesicle involvement. Twenty-seven patients received adjuvant treatment (orchiectomy, DES, radiation, or combinations of these); it was administered to patients with higher tumor grades, larger tumor bulk, and/or residual cancer. Overall actuarial survival at five and ten years was 85 per cent and 72 per cent, respectively; five-year nonprogression rate was 64 per cent. Local recurrence was noted in only 8 patients (7.6%). Radical surgical treatment for nonbulky Stage C disease of the prostate is associated with favorable survival results and good local control. Adjuvant treatment may favorably affect disease outcome. Clinical seminal vesicle involvement with negative urethrocystoscopy should not necessarily deter the surgeon from planning radical prostatectomy. Prospective adjuvant treatment protocols need to be developed to identify the value of adjuvant hormone and/or radiation therapy.
