Abstract:
Radical prostatectomy, external irradiation, and brachytherapy are currently available for the cure of early localized prostatic cancer. This report documents the first successful Iodine-125 seeds implant treatment of early prostatic cancer in Korea. Patient was 70-year-old man with mild urinary urgency and nocturia. Serum PSA (prostate specific antigen) was 6.51ng/ml. Transrectal ultrasonography showed a small, roundish, low echogenic lesion measuring 8mm in diameter in the left lower peripheral zone of the prostate. The volume of prostate was 27cc and biopsy revealed adenocarcinoma (Gleason score 7). MRI confirmed the presence of a small nodular lesion in the left peripheral zone without evidence of local invasion, and bone scintigraphy was unremarkable. The tumor was staged as T2a. We performed permanent implantation of Iodine-125 seeds using Mick procedure. The patient experienced immediate post-implant irritation of the bladder and urethra with hematuria. Follow up CT and radiography showed all seeds were remained in the same prostate as implanted. Follow up serum PSA was 1.85ng/ml at 3 months and 0.62ng/ml at 9 months after the procedure.
