Expression and clinical significance of adhesion molecule CD11c in gastric carcinoma

Abstract

Objectiye To investigate the expression of CD11c in gastric carcinoma and the clinical significance. Methods The expression of CD11 c in gastric carcinoma, gastritis tissue and gastric polyp was detected by using immunohistochemical assay. Results The expression level of CD11c in gastric carcinoma was higher than that in gastritis tissue and gastric polyp. There was no significant difference in the CD11 c expression among gender, age, pathological grade, primary area (P ＞ 0. 05 ). There was significant difference in the CD11c expression among tumor size, invasive depth, lymph node metastasis, histological type, recurrence and clinical stage. The expression of CD11c in tumor size ＜5 cm group ( 12.4 ±6. 8 ) was higher than that in tumor size ≥ 5 cm group (7.7 ± 4. 6), ( t = 3.98, P ＜ 0. 01 ). The expression of CD11c in non-invasion group ( 15.4 ± 8.5 ) was obviously higher than that in invasion group (9.5 ±5.6), ( t = 3.1 ,P ＜ 0. 05 ). The expression of CD11c in non-lymph node metastasis group ( 15.3 ± 6. 6 )was obviously higher than that in lymph node metastasis group ( 8. 6 ± 5. 1 ), ( t = 5. 44, P ＜ 0. 01 ). The expression of CD11c in non-recurrence group ( 12.3 ±7.4) was higher than that in recurrence group (9. 0± 5.3), ( t= 2.90, P ＜ 0. 01 ). The expression of CD11 c in differentiation group ( 9. 3 ± 5.3 ) was lower than that in low differentiation group ( 12. 6 ± 7. 8 ), ( t = 2. 68, P ＜ 0. 01 ). There was significant diference among groups of clinical stage (P ＜0. 01 ). The multivariate Cox analysis revealed that the risk of death in high expression group was significantly lower than that in low expression group (RR =0. 51, 95% CI=0. 22-1.16). Conclusion Detection of the CD11c expression in gastric carcinoma is beneficial to the judgment of the prognosis of gastric carcinoma and the choice of individualized treatment.
