PO-0817: Rectal bleeding and radiotherapy for prostate cancer. DVHs and potential clinical parameters

Feature extraction and classification for rectal bleeding in prostate cancer radiotherapy: A PCA based method

3-Dimensional conformal radiotherapy versus intensity modulated radiotherapy for localized prostate cancer: Dosimetric and radiobiologic analysis

 Background: To analyze the dosimetric and radio biologic advantages between intensity modulated radiotherapy (IMRT) and 3 dimensional conformal radiotherapy (3DCRT) and selection of optimal photon energy for IMRT treatments. Material and methods: 24 patients with localized prostate carcinoma were planned for 3DCRT and IMRT techniques. Radiation dose of 54 Gy with 2 Gy/fraction, was planned to ...

The effect of Rectal Retractor, a rectal protector on rectal dose in radical prostate radiotherapy

Introduction: The close proximity of the rectum tissue to the prostate gland results in rectal toxicity during prostate radiotherapy. Rectal Retractor (RR) is a rectal displacement technique that inserts into the rectum, as a result, the lateral and dorsal part of the rectal wall push away from high dose areas. The aim of this study was to investigate the dosimetric consequence...

Self-assessed bowel toxicity after external beam radiotherapy for prostate cancer - predictive factors on irritative symptoms, incontinence and rectal bleeding

BACKGROUND The aim of the study was to evaluate self-assessed bowel toxicity after radiotherapy (RT) for prostate cancer. In contrast to rectal bleeding, information concerning irritative symptoms (rectal urgency, pain) and incontinence after RT has not been adequately documented and reported in the past. METHODS Patients (n = 286) have been surveyed prospectively before (A), at the last day ...

Neoadjuvant radiotherapy and radiochemotherapy for rectal cancer.

Combined radiochemotherapy is the recommended standard postoperative therapy for patients with stage II and III rectal cancer in the USA and in Germany. During thelast decade, substantial progress has been made in treatment modalities: surgical management currently includes a broad spectrum of operative procedures ranging from radical operations such as abdominoperineal resections to innovative...
