Commentary (Seres/Harrison): Nutritional Support of Patients Undergoing Radiation Therapy for Head and Neck Cancer

March 01, 2005

Dr. Colasanto and his associatesare to be commended forskillfully and comprehensivelyreviewing the issues concerning theprovision of nutritional support to patientsundergoing radiation therapy.Their recommendations are well supportedby review of scientific studies,and the article is written in such a wayas to be accessible to those not fullyversed in prescribing nutritional support.There remain a few points thatdeserve discussion.

High-Dose-Rate Intraoperative Radiation Therapy For Colorectal Cancer

July 01, 1995

Intraoperative radiation therapy (IORT) has the obvious advantage of maximally irradiating the tumor bed while eliminating surrounding normal organs from the field of radiation. This approach has been especially useful when the required radiation dose exceeds the tolerance dose of the surrounding normal tissues. However, the application of IORT has been significantly limited by cost, logistic issues, and technical problems related to delivering treatment to difficult anatomic areas. We have developed a new approach to IORT that obviates the need for patient transport: In a dedicated, shielded operating room, the surgery is performed and IORT is delivered via HDR remote afterloading. We have found this approach to be cost effective, logistically sound, and suitable for a wide range of anatomic sites. The technical aspects of the procedure, as well our preliminary results in colorectal cancer, will be presented. Lastly, the authors present the technical aspects of delivering HDR intraoperative brachytherapy, their dosimetry atlas, and their results using HDR-IORT in the treatment of patients with colorectal cancer[ONCOLOGY 9(7):679-683, 1995]
