Randomized Controlled TrialRisk factors of late rectal bleeding after carbon ion therapy for prostate cancer.
The aim of this study was to determine the risk factors for late gastrointestinal (GI) morbidity after hypofractionated carbon ion radiotherapy (C-ion RT) for prostate cancer. ⋯ Although C-ion RT with hypofractionation yielded favorable results regarding late GI complication, dosimetric parameter was a very important factor in the occurrence of rectal bleeding after C-ion RT as well as photon beam RT. Our results provide useful information for physicians applying charged particle RT in the treatment of prostate cancer.

Results of the 2004 Association of Residents in Radiation Oncology (ARRO) survey.
The aim of this study was to document adequacy of training, career plans after residency, use of the in-service examination, and motivation for choice of radiation oncology as a specialty. ⋯ Multiple factors affect the educational environment of physicians in training. Data describing concerns unique to resident physicians in radiation oncology are limited. The current survey was designed to explore a variety of issues confronting radiation oncology residents. Training programs and the Residency Review Committee should consider these results when developing new policies to improve the educational experiences of residents in radiation oncology.

Comparative Study Controlled Clinical TrialIntensity-modulated radiotherapy significantly reduces xerostomia compared with conventional radiotherapy.
Xerostomia is a severe complication after radiotherapy for oropharyngeal cancer, as the salivary glands are in close proximity with the primary tumor. Intensity-modulated radiotherapy (IMRT) offers theoretical advantages for normal tissue sparing. A Phase II study was conducted to determine the value of IMRT for salivary output preservation compared with conventional radiotherapy (CRT). ⋯ IMRT significantly reduces the number of parotid flow complications for patients with oropharyngeal cancer.
