ABSTRACT
OBJECTIVE@#To investigate the relation between the expression of COX-2 protein and the effect of radiotherapy, estimate the value of COX-2 in predicting the effect of radiotherapy in patients with nasopharyngeal carcinoma,provide theoretical basement for establishing characteristic project of treatment and raising curative effect and life quantity.@*METHOD@#The expression of COX-2 protein was examined in 30 radiosensitive and 30 radioresistant poorly differentiated NPC by immunohistochemical staining (SP method) before radiotherapy. The relation between the expression of COX-2 and the effect of radiotherapy was analyzed.@*RESULT@#The positive rate of COX-2 protein expression was 61. 67% in NPC tissues, there was statistical difference( P <0. 01) of the positive rate between the 86. 67 % of 30 radioresistant and 36. 67 % of radiosensitive NPC tissues. The intensity of COX-2 protein expressions showed statistical difference( P <0. 05),too. Based on the expression of COX-2, the effect of radiotherapy, sensitivity, specificity, accuracy, positive predictive value, negative predictive value, false positive and false negative were predicted as follows 86. 67Y, 63. 33% ,75. 00%, 70. 27% ,82. 61% ,36. 67% and 13. 33 , respectively.@*CONCLUSION@#COX-2 expression may serve as a marker in predicting the response to radiotherapy in NPC. According to the expression of COX-2, the sound treatment scheme can be selected.
