Thirty-five patients with prostatic adenocarcinoma were treated by bilateral pelvic lymphadenectomy and temporary implantation of iridium 192 strands with adjuvant external beam radiotherapy. With the implant the prostate received between 3,200 and 3,500 gray (Gy) followed in two weeks by small-field external beam irradiation for an additional dose of approximately 3,400 Gy. Morbidity included an ileofemoral thrombosis in one patient, and transient radiation proctitis in four patients; one patient required transurethral prostatic resection for obstruction at one year. Local response of the primary tumor was dramatic in every case at three-month follow-up. In 11 of 15 patients (73%), biopsy at one year showed no evidence of disease.
35例前列腺腺癌患者接受了双侧盆腔淋巴结清扫术,并临时植入铱192线源,同时辅以体外照射放疗。植入时前列腺接受的剂量在3200至3500戈瑞(Gy)之间,两周后进行小野体外照射,追加剂量约3400 Gy。并发症包括1例患者发生髂股静脉血栓形成,4例患者出现短暂性放射性直肠炎;1例患者在1年后因梗阻需要行经尿道前列腺切除术。在3个月的随访中,每例患者原发肿瘤的局部反应都很显著。15例患者中有11例(73%)在1年时活检显示无疾病证据。
