Development of a wavelength-separated type scintillator with optical fiber (SOF) dosimeter to compensate for the Cerenkov radiation effect.

The scintillator with optical fiber (SOF) dosimeter consists of a miniature scintillator mounted on the tip of an optical fiber. The scintillator of the current SOF dosimeter is a 1-mm diameter hemisphere. For a scintillation dosimeter coupled with an optical fiber, measurement accuracy is influenced by signals due to Cerenkov radiation in the optical fiber.

Long-term outcome of hypofractionated radiotherapy to the whole breast of Japanese women after breast-conserving surgery.

Background: In Japan, there are still no reports of long-term outcome for hypofractionated radiotherapy to the whole breast after breast-conserving surgery (BCS). We report our institution's results from evaluation of the efficacy and safety of hypofractionated radiotherapy for Japanese women.

Methods: Data in the medical records of 327 patients were retrospectively reviewed.

Whole-breast radiotherapy with shorter fractionation schedules following breast-conserving surgery: short-term morbidity and preliminary outcomes.

Background: The success of whole-breast radiotherapy with shorter fractionation schedules following BCS has rarely been evaluated in Japanese women. Here we present the short-term morbidity and preliminary outcomes of the shorter fractionation regimen initiated at the Kawasaki Medical School Hospital in 2003.

Methods: Between January 2003 and December 2005, 248 patients (251 breasts) with breast cancer underwent short-course RT following BCS.

Clinical results of combined treatment conformal high-dose-rate iridium-192 brachytherapy and external beam radiotherapy using staging lymphadenectomy for localized prostate cancer.

Purpose: To report the first long-term biochemical control rate of patients treated with two protocols using a combination of external beam radiotherapy (EBRT) and high-dose-rate (HDR) brachytherapy for localized prostate cancer in Japan.

Methods And Materials: Between October 1997 and July 2001, 71 patients with localized prostatic adenocarcinoma were treated with a combination of EBRT and HDR brachytherapy. Patient age ranged from 58 to 81 years (mean 70.
