Methods: 66 specimens of tumor adjacent tissues, and 20 specimens of benign lesions were detected by SP immunohistochemistry; their interrelations and correlations to clinicopathologic features of NSCLC were analyzed. Results: Positive rate of Survivin in NSCLC was significantly higher than that in adjacent tissues and benign lesions (54.5% vs. 30 %, P < 0.05), its positive rate was 63.6% in lung adenocarcinoma tissues, and its positive rate was 54.5% in lung SCC, there was no significant difference between them. Its expressions were respectively 41.2%, 87.5% in well-differentiated and poorly differentiated lung SCC; its expressions were respectively 47.1%, 81.2% in well-differentiated and poorly differentiated lung adenocarcinoma; the discrepancy had statistical significance. Its expression was 74.1% in lymphatic metastasis group, which was obviously higher than that in no lymphatic metastasis group, which was 48.7%. The rate of MVD in Survivin positive group was obviously higher than that of Survivin negative group. Conclusion: The expression of Survivin is connected with the degree of differentiation on lung cancer and lymphatic metastasis, which indicates Survivin can be as an index for the judgment of condition and the evaluation of prognosis, the expression of Survivin is direct correlation with that of MVD. It is evident that Survivin functions the promotion of tumor angiogenesis.展开更多

Methods: A retrospective study from 63 postoperative patients all with small PLC (diameter ≤5 cm) was done. One group of 29 patients developed recurrence or metastasis within 2 years. The other group of 34 patients had no evidence of recurrence or metastasis within 2 years. Three sections were taken from each patient. One for H.E. staining, the other two for VEGF and Bio-UEA-I immunohistochemical staining respectively. MVD was counted by endothelial cells, which were highlighted by Bio-UEA-I. Results: The MVD of the recurrence (or metastasis) group (49.6±29.7) were significantly greater than the other, group (22.7±28.2) (P<0.01); The VEGF positive rate of the recurrence group was 86.2% (25/29), the rate of the other group was 47.1% (16/34). the difference between the 2 groups was stafistically significant (P<0.01). The stage of the tumor, the positive rate of satellite nodules and the positive rate of the portal vein embolus were all significantly different between the 2 groups. Conclusion: Besides tumor stage, satellite nodule and portal vein embolus, the MVD and VEGF are also of prognostic significance.展开更多
