Prostate cancer treated with reduced-volume intensity-modulated radiation therapy: Report on the 5-year outcome of a prospective series.

How to define a clinical target volume (CTV) as small as possible for prostate cancer to reduce the dose received by normal organs is an interesting study. We conduct a research to analyze the clinical efficacy of intensity modulated radiotherapy (IMRT) using reduced CTV in the treatment of prostate cancer. From January 2006 to June 2010, 78 patients with prostate cancer were treated with IMRT according to this institutional protocol.

Cervical cancer treated with reduced-volume intensity-modulated radiation therapy base on Sedlis criteria (NCCN VS RTOG).

Objective: This study aimed to evaluate the clinical efficacy of different target volumes in pelvic radiotherapy in postoperative treatment of cervical cancer based on the Sedlis criteria.

Methods: Patients who admitted to our department for post-operative radiotherapy of cervical cancer from December 2001 to December 2011 and met the Sedlis criteria were retrospectively analysed. The incidences of acute and late radiation injuries, and overall, disease-free and tumour-specific survival with reduced-volume pelvic and whole-pelvis radiotherapy were evaluated and compared.
