BACKGROUND The purpose of this study was to examine the long-term outcome of a cohort of patients with unresected base of tongue carcinoma who received interstitial brachytherapy after comprehensive external beam radiation therapy. METHODS Between 1983 and 2000, 122 patients with primary or recurrent squamous cell carcinoma of the oropharynx or oral cavity received interstitial brachytherapy ...
From January 2004 to March 2007, 308 patients with clinically localized prostate cancer were treated using iodine-125 (125I) seed implantation (permanent brachytherapy) at Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences. We evaluated the treatments efficacy and morbidity in 300 prostate cancer patients who were followed up for more than 1 month after brachy...
Evaluation of the effect of prostate volume change on tumor control probability in LDR brachytherapy
PURPOSE This study evaluates low dose-rate brachytherapy (LDR) prostate plans to determine the biological effect of dose degradation due to prostate volume changes. MATERIAL AND METHODS In this study, 39 patients were evaluated. Pre-implant prostate volume was determined using ultrasound. These images were used with the treatment planning system (Nucletron Spot Pro 3.1(®)) to create treatment...
PURPOSE To evaluate predictive factors for PSA bounce after 125I permanent seed prostate brachytherapy and identify criteria that distinguish between benign bounces and biochemical relapses. MATERIALS AND METHODS Men treated with exclusive permanent 125I seed brachytherapy from November 1999, with at least a 36 months follow-up were included. Bounce was defined as an increase ≥ 0.2 ng/ml abov...
Low-dose rate brachytherapy has become a mainstream treatment option for men diagnosed with prostate cancer because of excellent long-term treatment outcomes in low-, intermediate-, and high-risk patients. To a great extend due to patient lead advocacy for minimally invasive treatment options, high-quality prostate implants have become widely available in the US, Europe, and Japan. High-dose-ra...
