Acute morbidity of proton therapy for prostate cancer: the Hyogo Ion Beam Medical Center experience.
To investigate the incidence and influencing factors of acute genitourinary (GU) and gastrointestinal morbidities in patients with prostate cancer treated with proton therapy. ⋯ In our experience with proton therapy, a low incidence of acute gastrointestinal morbidity was observed. In contrast, the incidence of acute GU morbidity was similar to that in other reports of photon radiotherapy. Additional follow-up is warranted to elucidate the long-term safety and efficacy of proton therapy for prostate cancer.

Dose-dependent pulmonary toxicity after postoperative intensity-modulated radiotherapy for malignant pleural mesothelioma.
To determine the incidence of fatal pulmonary events after extrapleural pneumonectomy and hemithoracic intensity-modulated radiotherapy (IMRT) for malignant pleural mesothelioma. ⋯ The results of our study have shown that fatal pulmonary toxicities were associated with radiation to the contralateral lung. V20 was the only independent determinant for risk of PRD or non-cancer-related death. The mean V20 of the non-PRD patients was considerably lower than that accepted during standard thoracic radiotherapy, implying that the V20 should be kept as low as possible after extrapleural pneumonectomy.

To provide an extensive and detailed portrait of radiation oncologists, their professional activities, and the practices in which they work. ⋯ Despite concerns in 2003 about lower-than-optimal workload, professional satisfaction, if anything, increased since 1995.

Impact of fraction size on cardiac mortality in women treated with tangential radiotherapy for localized breast cancer.
To determine whether fraction size affects the risk of cardiac mortality in women treated with adjuvant radiotherapy (RT) for left-sided breast cancer. ⋯ There was no evidence for increased risk of cardiac mortality in women treated with adjuvant RT after a median follow-up of 7.9 years in our cohort. Hypofractionated adjuvant RT regimens did not significantly increase the risk of cardiac mortality.

Ontario radiation oncology residents' needs in the first postgraduate year-residents' perspective survey.
To assess radiation oncology residents' needs and satisfaction in their first postgraduate year (PGY-1) in the province of Ontario. ⋯ Most Ontario residents were satisfied with their PGY-1 training program. More counseling by radiation oncology faculty members should be offered to help residents with career planning. The residents might also benefit from more exposure to "radiation oncology" and an introduction to stress management strategies.
