Management of prostate carcinoma. Combination of pelvic lymphadenectomy, temporary Ir-192 implantation, and external irradiation.
Forty patients with prostate adenocarcinoma had bilateral pelvic lymphadenectomy, temporary Ir-192 implantation, and external irradiation. With the implant, the prostate received less than or equal to 3,000 rad (30 Gy) for A2 and B1 and 3,500 rad (35 Gy) for B2 and C lesions in 40-45 hours. Ten days to 2 weeks later, 4,000 rad (40 Gy) external irradiation was given in 4-5 weeks using AP and PA parallel opposed fields, a "box," or rotation. Patients with positive nodes were given 5,000 rad (50 Gy) to the pelvis with a midline block at 4,000 rad (40 Gy) so that the prostate received 7,000-7,500 rad (70-75 Gy). All patients were free of local recurrence. Treatment was tolerated well, with rapid regression and few complications.
