Iodine 125 seed implants for prostatic carcinoma. Five- and ten-year follow-up

Between 1975 and 1985 132 patients underwent bilateral pelvic lymphadenectomy and insertion of Iodine 125 seeds for biopsy-proved localized carcinoma of the prostate. Surgical stages were A2 9 percent, B 64 percent, C 9 percent, and D1 18 percent. Operative mortality was zero. Short and long-term complications were less than 33 percent. Ten-year survival rates of evaluable patients for surgical Stages A2, B1, B2, and C1 were 75 percent, 70 percent, 48 percent, and 44 percent, respectively. For these patients, ten-year disease-free rates for Stages A2, B1, B2, and C1 were 67 percent, 36 percent, 60 percent, and 25 percent, respectively. Interstitial radiotherapy may play a role in the treatment of nonsurgical candidates with low volume and well- to moderately-differentiated adenocarcinoma of the prostate.
