Whole abdominopelvic intensity-modulated radiation therapy for desmoplastic small round cell tumor after surgery.
Desmoplastic small round cell tumor (DSCRT) is an uncommon pediatric tumor with a poor prognosis. Aggressive multimodality therapy is the current treatment approach; however. treatment toxicity is of concern. We report our results with whole abdominopelvic intensity-modulated radiation therapy (WAP-IMRT) as a component of multimodality therapy for DSCRT at a single institution. ⋯ WAP-IMRT with concurrent radiosensitizing chemotherapy was well tolerated after aggressive surgery for DSCRT. Enhanced bone sparing with IMRT probably accounts for the low hematologic toxicity (vs. conventional WAP-RT). This modality should be considered as an additional local-regional control option for DSRCT.

Patterns of practice in palliative radiotherapy for painful bone metastases: a survey in Japan.
To determine the current patterns of practice in Japan and to investigate factors that may make clinicians reluctant to use single-fraction radiotherapy (SF-RT). ⋯ Japanese radiation oncologists prefer a schedule of 30 Gy in 10 fractions and are less likely to recommend SF-RT. Most Japanese radiation oncologists regard MF-RT as superior to SF-RT, based primarily on the time until first increase in pain.

Coordination of breast cancer care between radiation oncologists and surgeons: a survey study.
To assess whether radiation oncologists and surgeons differ in their attitudes regarding the local management of breast cancer, and to examine coordination of care between these specialists. ⋯ Despite the widespread availability of tumor boards, a substantial minority of radiation oncologists indicated other providers failed to include them in the breast cancer treatment decision-making process early enough. Earlier inclusion of radiation oncologists may influence patient decisions, and interventions to facilitate this should be considered.

Outcome after conformal salvage radiotherapy in patients with rising prostate-specific antigen levels after radical prostatectomy.
This study attempts to improve our understanding of the role of salvage radiotherapy (SRT) in patients with prostate-specific antigen (PSA) relapse after radical prostatectomy with regard to biochemical control, rate of distant metastasis, and survival. ⋯ Men with postoperative PSA relapse can undergo salvage treatment by prostate bed radiotherapy, but durable PSA control is maintained only in about one-third of the patients. Despite a high biochemical failure rate after SRT, prostate cancer-specific survival does not decrease rapidly.
