RESUMEN
Objective To evaluate the expressions and roles of survivin (SVV), bcl-2 and proliferating cell nuclear antigen(PCNA) in cutaneous squamous cell carcinoma (SCC). Methods The expressions of SVV, bcl-2 and PCNA were investigated by SP immunohistochemistry technique in 82 cases of SCC and 18 normal skin samples. Results There were 79.3% of SCC patients with the expression of SVV (P
RESUMEN
Objective To investigate the expression and clinical significance of survivin and proliferating cell nuclear antigen(PCNA) in human esophageal carcinoma. [WTHZ]Methods The expression of survivin and PCNA was detected by immunohistochemical SP method in 98 cases of esophageal carcinoma and paired normal mucosa adjancent to tumor. Results The positive rate of survivin expression in esophageal carcinoma and normal mucosa adjancent to tumor was 80.6% and 7.1%, respectively, which was obviously higher in the former than in the latter(P
RESUMEN
Objective To explore the expression and clinical significance of survivin protein and proliferation cell nuclear antigen(PCNA) in human nasopharyngeal carcinoma (NPC). Methods The expression of survivin protein and PCNA was detected by SP immunohistochemical technique in 96 cases of NPC tissues. Results The positive rate of survivin expression was 75.0% in PNC. Labeling idex(LI) of PCNA in survine positive NPC was higher than that in survivin negative NPC. The positive rate of survivin expression in NPC with neck lymph node metastasis was higher than that in NPC without neck lymph node metastasis. The positive rate of survivin expression in NPC patients with less than 5-year survival rate was higher than that in NPC patients with over 5-year survival rate. Conclusion NPC had survivin expression, and survivin expression in NPC was positive related with PCNA expression. The survivin protein might promote the neck lymph node metastasis of NPC cells. The prognosis of the patients with survivin positive NPC was worse.
