125Iodine implantation after lymphadenectomy in early carcinoma of the prostate (original) (raw)

Int J Radiat Oncol Biol Phys, 1986

Abstract

The interim results of planned lymphadenectomy and 125Iodine implantation for carcinoma of the prostate in 122 patients are reported. The incidence of positive pelvic lymph nodes found at lymphadenectomy ranged from 15% in A-2 to 55% in B-2 lesions, as well as in 13% of well-differentiated tumors. Poorly differentiated histology, B-2 and D-1 tumors, had early treatment failure indicating a group of patients in whom this procedure is contraindicated. Occult disease (A-2) and well-differentiated tumors do not exhibit early failure. However, these patients will also fare well with radical external radiation or prostatectomy. The radiobiology of the low dose rate continuous irradiation of 125Iodine is questioned. It may be inadequate for long-term tumor control. Longer follow-up of this series may indicate that external radiation for clinically localized carcinoma of the prostate is the most effective treatment policy.
