Methods: A total of 207 surgical specimens diagnosed as NSCLC were included in this study. Double-staining procedures were performed using antigen Ki-67 (clone MIB-1) and silver nitrate by immunohistochemical and AgNOR-staining methods. Results: The AgNOR area in MIB-l-positive cells of NSCLC is related to clinicopathological parameters under the TNM (tumor, node, and metastasis) system. The survival of patients with small AgNOR area in MIB-1-positive cells is better than that of patients with large AgNOR area. Molecular, biological (AgNOR area in MIB-l-positive cells), and clinicopathological (greatest tumor dimension, metastases to regional lymph nodes, histology, and differentiation) parameters are independent prognostic factors of NSCLC.Conclusion: The AgNOR area in MIB- 1-positive cells is related to clinicopathological parameters and survival in NSCLC.展开更多

Whereas by far, there is few study concerning the combination of MIB-1 proliferation index (MIB-1 PI) and tumor angiogenesis in carcinomas to show their significance in relate to clinicopathological parameters. In the present study, we evaluated the significance or MIB-1 PI and angiogenesis in early stage of gastric cancer. Our focus was es- pecially on the combination of MIB-1 PI and angiogenesis in relate to lymph node metastasis. Method Specimens from 95 patients with early gastric cancer were studied by means or immunohistochemistry using monoclonal MIB-1 and factor Ⅷ related antigen antibodies. Results The mean MIB-1 PI and microvessel count were 22.9% and 34.7, respectively. The MIB-1 PI did not correlate with microvessel count. Both correlated with depth of tumor invasion, lymphatic vessel invasion and lymph node metastasis. Multivarlate analysis showed that combined high MIB-1 PI/hy- pervascularity, as well as lymphatic vessel invasion and tumor size were independent factors that impact on lymph node metastasis. Conclusion A combination of the high MIB-1 PI/hypervascularity is a factor that related to lymph node metastasis in early gastric cancer.展开更多
