Advances in rectal malignancy

Recent Advances in Rectal Cancer

Predicting malignancy in thyroid nodules: molecular advances.

Over the last several years, a clearer understanding has developed of the genetic alterations underlying thyroid carcinogenesis. This knowledge can be used to tackle 1 of the challenges facing thyroidologists: management of the indeterminate thyroid nodule. Despite the accuracy of fine-needle aspiration cytology, many patients undergo surgery to diagnose malignancy and better diagnostic tools a...

Advances in radiotherapy in operable rectal cancer.

AIMS Radiotherapy (RT) reduces local recurrence in rectal cancer but the optimal treatment schedule is unknown. Relevant questions in designing optimal therapy are set out. This review identifies evidence that influences current practice and shapes future trials in treatment of operable rectal cancer. METHODS PubMed and MEDLINE search. RESULTS RT reduces local recurrence and pre-operative t...

Mucosal Prolapse Polyp Mimicking Rectal Malignancy: A Case Report

Mucosal prolapse polyps (MPPs) are rare inflammatory lesions that are part of the mucosal prolapse syndrome. We present the case of a 40-year-old male with history of constipation referred to our institution with suspected rectal malignancy due to hematochezia and a palpable rectal mass. Colonoscopy revealed a 25 mm wide lesion suggestive of subepithelial origin but with marked erythema and ero...

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...
