Abstract

BACKGROUND: Combination of permanent interstitial brachytherapy based on radioactive iodine with external beam radiotherapy is an alternative to other treatment modalities, such as radical prostatectomy or external beam radiotherapy alone in patients with intermediate-risk localized prostate cancer. In this article we report our experience with this combination modality. METHODS: Among patients who were treated in our institute with brachytherapy, there were 64 patients who received combination therapy for the above indication. Combination therapy enables administration of 110 Gy as brachytherapy and thereafter 45 Gy as external beam radiation. All patients received adjuvant androgen deprivation therapy for 6 months. The prospective follow-up was done with the aid of validated evaluation instruments (questionnaires). RESULTS: Combination therapy was administered without additional urinary (IPSS-based) or sexual (IIEF-based) side effects above those with brachytherapy alone. No severe perianal and lower intestinal tract side effects were observed. Short-to-moderate-term results based on serum PSA levels are encouraging, and are not inferior to what is accepted by the literature for other radical therapies. CONCLUSION: Combination of permanent interstitial brachytherapy and external beam radiotherapy in the appropriate patients does not cause any additional morbidity, and its biochemical results justify its application. This modality should be offered as an accepted and good alternative to other radical treatment options, to men with prostate cancer with moderate risk factors.
