Surgical therapy for localized prostatic carcinoma

Abstract

The intraoperative, immediate postoperative, and late postoperative morbility and prostate-specific antigen (PSA) levels in 511 consecutive patients with clinical T1b, T1c, and T2 tumors, who underwent anatomical radical retropubic prostatectomy, have been discussed. Between 1988 and 1995, prostatic cancer was diagnosed in 511 patients on the basis of PSA and prostate biopsy, when life expectancy was more than 10 years and frozen sections of obturator lymph nodes were negative. All specimens were cut into 3 mm sections by the step-section technique, after the surgical margin had been inked with formalin-resistant dye to identify the margin status. The mean age of the 511 patients was 63.4 years. Blood loss during the operation decreased to 986 ml in the last 2 years. Of the patients, 4.3% had intraoperative rectal perforation; only 5 required a second operation, which was done with a simple rectal approach. Ureteral injury occurred in 1.4% and this was repaired during the operation; 11% had prolonged lymphocele; all were treated conservatively. Deep-venous thromboses were seen in 3.7%; 5 patients (1%) had pulmonary embolism, which was lethal in 3 patients (0.6% of the whole group). There were no intraoperative deaths. No patient death was observed in the last 3 years, when all lymphoceles were diagnosed with thorough ultrasonographic evaluation and drained immediately. Complete continence after 1 year was achieved in 92% of the patients; 5.8% of the patients had anastomotic stricture; most were treated with a single calibration. Twelve months after the operation, 80% of the patients had no measurable PSA. There was a clear correlation of PSA negativity to tumor stage. Anatomical radical prostatectomy is safe and can cure about 70% of patients with clinical T1b,T1c, and T2 prostatic tumors.
