摘要:: The occurrence and development of tumors are controled by oncogene, antioncogene and tumor metastasis-related gene. Cyclin D1 is the expressive product of CCND1(a kind of oncogen). Vascular endothelial growth factor (VEGF) regulates the growth of neoplastic angiogenesis, which plays a role in the invasion and metastasis of tumor. The objective of this study was to detect the expression of Cyclin D1 and VEGF in non-small cell lung cancer (NSCLC), and to explore their association with the prognosis of NSCLC.,Immunohistochemistry was used to detect the expression of Cyclin D1 and VEGF in pathological tissue sections of 55 cases of NSCLC and 10 cases of non-malignant tissue from lung lesions. The relationship between the expression of Cyclin D1 and VEGF in 55 NSCLC sections and the age, sex, smoke, size of tumor, histopathological type, differentiation, stage, lymph node metastasis and survival time were analyzed statistically.,The expression rates of Cyclin D1 and VEGF in the 55 NSCLC tissue sections were 61.82% and 74.55%, respectively. In 10 cases of non-malignant tissue sections, cyclin D1 expression was not detected and VEGF expression (+/-) was only in 2 cases. The expression of Cyclin D1 and VEGF showed: (1) there was no significant difference among age, sex, histopathological type, stage, differentiation, tumor size and smoking level; (2) there were significant differences between the patients with and without lymph node metastasis; (3) there were significant differences of survival time between positive and negative expression groups. It meant Cyclin D1 and VEGF would be the poor prognostic factors.,The expression of Cyclin D1 and VEGF occurred in more than 60% cases of NSCLC, which may play a role in the biologic behavior and prognosis of NSCLC.
