Role of p53 and p21/WAF1 detection in patient selection for preoperative radiotherapy in rectal cancer patients

Abstract
BACKGROUND:Recent studies showed that p53 and p21 may play major roles in determining tumor radiosensitivity through the apoptosis pathway. The aim of this study was to investigate the predicting value of radiosensitivity in human rectal carcinoma.METHODS:p53 and p21/WAF1 expressions in form
