Abstract:
Objective To investigate the relationship between the co-expression of CD105 and cyclin D1 and lymph node metastasis and prognosis of esophageal squamous cell carcinoma ( ESCC ). Methods Eighty cases of ESCC tissue were collected at The First People's Hospital of Nantong. The expression of CD105 and cyclin D1 of ESCC was detected by immunohistochemistry. The relationship between the co-expression of CD105 and cyclin D1 and lymph node metastasis and prognosis of ESCC was analysed. Eighty normal esophageal tissues were selected as controls. All data were analysed by t test, chi-square test, and Pearson correlation analysis. Survival was analysed by the Kaplan-Meier survival curve. Microvessel density (MVD) was used to indicate the expression of CD105 in the form of -x±s. Results The expression of CD105 in ESCC tissues was higher (36±8) than that in normal esophageal tissues ( 11±3) (t =25. 129, P＜0.05). The positive rate of cyclin D1 expression in ESCC tissues was 61% (49/80), which was significantly higher than 23% (18/80) in normal esophageal tissues ( x2 =4.972, P＜0.05). The MVD value of 44 patients was ≤36 (LCD105), and nine of them had lymph node metastasis. The MVD value of the remaining 36 patient was ＞ 36 ( HCD105 ), and 26 of them had lymph node metastasis. Twenty-eight patients with positive expression of cyclin D1 had lymph node metastasis, while seven patients with negative expression of cyclin D1 had lymph node metastasis. The results of Pearson correlation analysis revealed that a high expression of CD105 and a positive cyclin D1 expression were correlated with lymph node metastasis (x2 =21.562, 9.217, P＜0.05). The survival times of 28 patients with positive cyclin D1 and HCD105,21 patients with positive cyclin D1 and LCD105, eight patients with negative cyclin D1 and HCD105, and 23 patients with negative cyclin D1 and LCD105 were (31±6) months, (47±7) months, (51±9) months and (61±5) months, respectively, with a significant difference among the four groups (F = 11.76, P ＜ 0. 05 ).Conclusion Co-expression of CD105 and cyclin D1 may be used as a prognostic factor of ESCC.
