Abstract

Purpose: To summarize the urinary, rectal, and sexual symptoms occuring during the first 12 months following 125I prostatic implantation. Methods and Materials: Thirty-one patients with Stage T1 or T2 prostatic carcinoma were evaluated for morbidity following computed tomography-guided transperineal 1251 implants from 1988 to 1991. The median total activity used was 47 mCi (range 35-73 mCi). Toxicity was evaluated using a modification of the Radiation Therapy Oncology Group grading system. Results: Nocturia was the most common treatment-related symptom, reported by 80% of patients within 2 months after implantation, and persisted at 12 months in 45% of the patients. Mild dysuria developed in 48% of patients within 2 months of implantation; two patients needed analgesics for their dysuria. Terazosin hydrochloride (2-10 mg qd) provided subjective improvement of urinary symptoms in seven of eight patients in whom it was tried. Rectal urgency, soft stools, and increased frequency of bowel movements was reported by 25% of the patients within 1-2 months after implantation. The incidence of assymptomatic rectal bleeding or ulceration occurring at any time after implantation was 47%, but resolved in all patients with expectant treatment. Self-limited ulceration of the rectal mucosal occurred in 16%, but only one patient developed a prostato-rectal fistula, managed with an ileal conduit. Five of the 18 potent patients experienced discomfort on erection or ejaculation, beginning within several weeks of their implant. The discomfort resolved within 6 months in three of the patients, but persisted for 18 and 24 months in the other two. Conclusion: 125I implantation, as performed in this series, is generally associated with only mild-moderate genitourinary and rectal symptoms that may persist 6 months or more after implantation.
