Progress on study of predicting radiosensitivity of esophageal carcinoma / 国际肿瘤学杂志

ABSTRACT

The radiosensitivity of esophageal carcinoma is one of the bases for making dividualized treatment program.Predition of radiosensitivity before radiotherapy has become a hot spot of the current study.It has been demonstrated that radiosensitivity of esophageal carcinoma is correlated to p53 portein,bcl-2portein,human epidermal growth factor receptors (hEGFR),vascular endothelial growth factor (VEGF),hypoxia-inducible-factor-1 (HIF-1),cyclooxygenase-2(COX-2) and so on.Detection of these markers may be helpful for predicting the radiosensitivity of esophageal carcinonla and making optimal treatment program.In addition,radiosensitivity of tumor can be predicted according to radiation-induced esophagitis grade and endiscopic uhrasonography(EUS).
