[Expression and its significance of STAT3, STAT5, Survivin and Ki67 in nasal NK/T cell lymphoma].

Abstract

Objective: To study the expression and its significance of STAT3, STAT5, Survivin and Ki67 in the Epstein-Barr virus associated nasal NK/T cell lymphoma.

Method: The expression of STAT3, STAT5, Survivin and Ki67 were detected with immunohistochemistry in 25 cases of nasal NK/T cell lymphoma, and their relationship was analyzed. Nasal cavity tissues from 20 cases of chronic sinusitis were as the control group.

Result: The positive rates of STAT3 in the lymphoma and in control group were 56% and 10%, respectively (P <0.01). The positive rates of STAT5 in the lymphoma and in control group were 68% and 15%, respectively (P <0.01). The positive rates of Survivin and Ki67 of nasal NK/T cell-lymphoma were 68% and 72%, respectively; but it in the control group was 0% and 20%, respectively, P <0.01. The expression of STAT3 was positively related to that of Survivin and Ki67(r =0. 428, P <0. 05 and r =0. 704, P <0. 01); The expression of STAT5 was not related to that of Survivin and Ki67.

Conclusion: The pathway of STAT may play a role in the development of nasal NK/T cell lymphoma. STAT maybe take part in the formation of nasal NK/T cell lymphoma through induction of Survivin and Ki67.
