ABSTRACT
PURPOSE:
To provide a preliminary report of 301 patients treated for prostate carcinoma with three-dimensional CT-guided transischiorectal stereotactic brachytherapy using either iodine-125 or palladium-103 seeds as monotherapy. PATIENTS ANDMETHODS:
Patients with clinical stage T1, T(2ab), or T(3ab) disease with prostate volumes 23 to 180 cm3 and serum prostate specific antigen (PSA) concentrations of 0.9 to 143 ng/mL had seeds placed 10 mm apart under CT guidance. No androgen blockade was used postoperatively, but 47% of the patients had hormonal therapy preoperatively.RESULTS:
At 12 to 63 months (median 26 months) of follow-up, PSA concentrations had decreased to <2 ng/mL in 90% of the patients and to <1 ng/mL in 83%. Four patients underwent transurethral resection or incision at least 12 months after implantation; none became incontinent. Three patients had rectal ulceration that lasted for several months.CONCLUSIONS:
Computed tomography-guided transischiorectal brachytherapy allows accurate placement of radionuclide seeds in prostate glands of all sizes. The early results, as judged by serum PSA, are encouraging.
