Carotid dosimetry after re-irradiation with 131Cs permanent implant brachytherapy in recurrent, resected head and neck cancer

Edema‐induced changes in tumor cell surviving fraction and tumor control probability in  131Cs permanent prostate brachytherapy implant patients

The study is designed to investigate the effect of edema on the delivered dose, tumor cell surviving fraction (SF), and tumor control probability (TCP) in the patients of prostate cancer who underwent (131)Cs permanent seed implantation. The dose reduction, the SF, and the TCP for edematous prostate implants were calculated for 31 patients who underwent real-time (131)Cs permanent seed implanta...

A retrospective study of head and neck re-irradiation for patients with recurrent or second primary head and neck cancer: the McGill University experience

BACKGROUND We report our experience with patients who received re-irradiation to the head and neck area for locoregional recurrences (LRR) or second primaries (SP) in a previously irradiated field. METHODS We reviewed 27 consecutive patients with a diagnosis of LRR or SP head and neck carcinoma treated with a second course of radiotherapy between April 2004 and July 2012. The main outcome mea...

Re-irradiation of recurrent esophageal cancer after primary definitive radiotherapy

PURPOSE For recurrent esophageal cancer after primary definitive radiotherapy, no general treatment guidelines are available. We evaluated the toxicities and clinical outcomes of re-irradiation (re-RT) for recurrent esophageal cancer. MATERIALS AND METHODS We analyzed 10 patients with recurrent esophageal cancer treated with re-RT after primary definitive radiotherapy. The median time interva...

Pattern of Gustatory Impairment and Its Recovery after Head and Neck Irradiation

Introduction: Themajority of patients receiving concurrent chemoradiotherapy frequently complain of changes in their taste perception, and other distressing symptoms affecting their quality of life. This study was undertaken to determine the pattern of gustatory impairment and its recovery in irradiated head and neck cancer patients in India.   Materials and Methods: Thirty patients undergoing ...
