Abstract:
Objective To investigate the expression change of inhibitory member of the ASPP family(iASPP) and its relationship with clinicopathological features and prognosis in the patients with nasopharyngeal carcinoma(NPC).Methods One hundred and thirty-three cases of nasopharyngeal carcinoma confirmed by pathology in the hospital were selected,at the same time 30 cases of nasopharyngeal chronic mucositis biopsy paraffin blocks previously collected in the pathology department served as the control group.The immunohistochemical staining was used to compare the expression of iASPP protein in the two groups and the relationship between the expression of iASPP with the clinicopathologic characteristics and prognosis in the patients with NPC was analyzed.Results The positive expression of iASPP protein in the nasopharyngeal carcinoma tissue was 72.18％,which was higher than 20.00％ in the control group(P＜0.05);the positive expression of iASPP protein in the nasopharyngeal carcinoma tissue had a certain relationship with the primary tumor range and lymph node metastasis(P＜0.05);92 cases of nasopharyngeal carcinoma were followed up,including 63 cases of iASPP protein positive expression and 29 cases of iASPP protein negative expression,the 5-year survival rate in the patients with iASPP protein positive expression was 71.43％,which in the patients with iASPP protein negative expression was 86.21％,the difference was not statistically significant(P＞0.05).Conclusion The iASPP expression in the nasopharyngeal carcinoma tissue is up-regulated,which is related to the lymph node metastasis and the primary tumor range,but its influence on the patient's prognosis is not significant.
