OBJECTIVE To assess the safety and efficacy of hyperbaric oxygen (HBO) for treating radiation cystitis a long-term follow-up study was done in patients with prostate cancer, the second most common malignancy in Japan. PATIENTS AND METHODS A total of 38 patients at an age of 68 ± 8 years with radiation cystitis following irradiation of prostate cancer were(More)
BACKGROUND The results of BCT in Japanese women have not been fully evaluated. The Tokyo Women's Medical University Breast Cancer Society initiated BCT protocols in 1987. Here, we present a retrospective analysis of BCT outcomes and identify prognostic factors. METHODS The study population comprised 348 patients (353 breasts) with UICC clinical stage 0,I(More)
BACKGROUND The relationship between a positive resection margin and the risk of ipsilateral breast tumor recurrence (IBTR) is controversial. To evaluate the radiation dose and other factors influencing the ipsilateral breast tumor control (IBTC) in patients with positive or close resection margins after breast conserving surgery (BCS), the Japanese(More)
PURPOSE To analyze the outcomes of patients with early hypopharyngeal cancer treated with radical radiotherapy (RT). METHODS AND MATERIALS Ten institutions combined the data from 115 patients with Stage I-II hypopharyngeal squamous cell carcinoma treated with definitive RT between 1990 and 2001. The median patient age was 67 years; 99 patients were men(More)

Acoustic neuroma tumor size may be evaluated using several methods. Here we investigate the variations among measuring techniques. A retrospective analysis of pre- and posttreatment magnetic resonance (MR) scans was performed on 15 acoustic neuroma patients with a history of stereotactic radiosurgery who had been followed for more than 2 years. Tumor size(More)
BACKGROUND Docetaxel has shown remarkable radiosensitizing properties in vitro. In this study we investigated whether the addition of docetaxel to radiotherapy enhanced tumor response in patients with advanced or recurrent breast cancer. METHODS A total of 35 patients were enrolled in this study. Docetaxel was administered concurrently during(More)
PURPOSE Severe acute radiation dermatitis is observed in approximately 5% to 10% of patients who receive whole-breast radiotherapy. Several factors, including treatment-related and patient-oriented factors, are involved in susceptibility to severe dermatitis. Genetic factors are also thought to be related to a patient's susceptibility to severe dermatitis.(More)
OBJECTIVE A nationwide survey was performed to investigate the current patterns of care for brain metastasis (BM) from breast cancer in Japan.
