Failure of open radioactive 125iodine implantation to control localized prostate cancer: a study of 41 patients.
We studied 41 patients with localized prostate cancer who underwent bilateral pelvic lymphadenectomy with open insertion of radioactive 125iodine. Followup was a minimum of 5 years. Of the patients 13 died: 10 of recurrent prostatic adenocarcinoma (including 4 of 5 with pathological stage D1 cancer) and 3 of unrelated causes within 2 years of implantation without clinical evidence of prostate cancer. Of the 28 remaining patients 16 have known recurrence of cancer (positive bone scan and increasing prostate specific antigen (PSA) level or positive tissue biopsy]. Six patients have strong suspicion of local recurrence with elevated PSA levels (greater than 4.0 in 5) and increasing induration on digital rectal examination. Only 6 of the 41 patients (14.6%) are without evidence of disease. Openly implanted radioactive 125iodine does not appear to control effectively adenocarcinoma of the prostate.
