PURPOSE To evaluate the outcome of adjuvant and salvage radiotherapy (RT) after radical prostatectomy (RP) for clinically localized prostate cancer using conventional clinical end-points, and the biochemical relapse-free rate (bRFR). METHODS Between 1987 and 1994, 113 node negative, hormonally naïve men received RT 1 month to 12 years after RP. Adjuvant(More)
PURPOSE To assess the local control and survival in patients who received pelvic irradiation for locally recurrent rectal carcinoma. METHODS AND MATERIALS The records of 519 patients with locally recurrent rectal carcinoma treated principally with external-beam radiation therapy between 1975 to 1985 at a single institute were retrospectively reviewed.(More)
BACKGROUND AND PURPOSE Urethral carcinoma in women is uncommon. This study was undertaken to evaluate the role of radiotherapy in the treatment of these tumors. MATERIALS AND METHODS The hospital records of 34 women with primary urethral carcinoma were retrospectively reviewed. There were 15 squamous cell carcinomas, 13 transitional cell carcinomas, and(More)
The potential use of distraction osteogenesis in mandibular reconstruction has been limited by its questionable efficacy in previously radiated bone. We studied five mongrel dogs that had a hemimandible rendered edentulous and underwent a full course of external beam radiation therapy (50 Gy/20 fractions). Six months after completion of radiotherapy, a 2-cm(More)
PURPOSE To assess the outcome following local excision and postoperative radiotherapy (RT) for distal rectal carcinoma. MATERIALS AND METHODS Seventy-three patients received postoperative radiotherapy following local surgery for primary rectal carcinoma at Princess Margaret Hospital from 1983 to 1998. Selection factors for postoperative RT were patient(More)
BACKGROUND AND PURPOSE It is necessary to include the entire prostate in the high dose treatment volume when planning radical radiation for patients with prostate cancer. We prospectively compared magnetic resonance imaging (MRI) to computed tomography (CT) and urethrography as means of localizing the prostatic apex. MATERIALS AND METHODS Thirty patients(More)
A retrospective analysis was performed of patients with squamous cell carcinoma of the oesophagus without evidence of distant metastases, who were treated with radical intent. Between 1981 and 1984, and 1989 and 1991, 98 patients were treated with radiation, 5-fluorouracil (5-FU) and mitomycin C; and between 1984 and 1989, 133 patients were treated with(More)
Cyclical mastopathy (CM) is a common clinical syndrome of premenstrual breast swelling and tenderness. Its symptoms are relieved by reduction in dietary fat intake and, because fat intake may be associated with breast cancer risk, it was hypothesized that CM may also be related to breast cancer risk. This case-control study included 192 premenopausal women(More)

The aim of the present study was to investigate the effect of radiation treatment both on skin tissue expansion with the chronic inflation of subcutaneous expanders and on skin flap viability in surgically delayed and expanded skin in the pig. One flank in each of six pigs (initially weighing 17 +/- 1.8 kg) was randomly assigned for radiation treatment, and(More)
