Methods： The expression of HIF-1α was detected in 68 human non-small lung cancer samples by immunohistochemistry. Results： （1） Thirty-nine （57.35%） out of the 68 human non-small lung cancer samples was positive for HIF-1α ; （2） The positive rate of HIF-1α in adenocarcinoma and squamous carcinoma was 54.76% （23/42） and 61.54% （16/26） respectively. No significant difference was found between adenocarcinoma and squamous carcinoma of non-small lung cancer in the expression of HIF-1α （P〉0.05）. The positive rate of HIF-1α in middle-high differentiation was 74.28% （26/35）, significantly higher than in low differentiation （39.39%, 13/33） （P〈0.05）; （3） The positive expression of HIF-1α was not correlated to the sexes, ages, tumor stage and lymph node status. Conclusion： The expression of HIF-1α is higher in non-small lung cancer and is correlated to differentiation.展开更多

Results： The positive expression rate of c-erbB-2 was 26.1% （12/46） in the 46 cases of esophageal carcinoma, of which 4 cases being low expression and 8 cases mediumhigh expression. The positive expression rate of P-gp was 60.9% （28/46） in the 46 cases of esophageal carcinoma, of which 6 cases being low expression, 13 cases medium expression and 9 cases high expression. Comparing c-erbB-2 with P-gp expression in different lymph node metastasis statuses showed that there was significant difference （P〈0.01） between P-gp expressions with lymph node metastasis （31.09%±5.33%） and without lymph node metastasis （8.04%±3.03%） when c-erbB-2 expression was positive. Comparing c-erbB-2 with P-gp expression in different TNM stages of esophageal carcinoma showed that there was significant difference （P〈0.01） between P-gp expressions in HI Ⅳ stage （33.68%±5.51%）and in Ⅱ stage patients （9.30%±2.78%） when c-erbB-2 expression was positive. The tumor＇s size and differentiation degree were not related to c-erbB-2 and P-gp expression. Conclusion： The high level of P-gp expression was related to the positive expression of c-erbB-2 with the lymph node metastasis in clinical Ⅲ-Ⅳ stage patients of esophageal carcinoma, suggesting that the double positive might lead to a poor prognosis. However, when the c-erbB-2 expression was negative, the lymph node metastasis and clinical staging were not related to the P-gp expression in esophageal carcinoma patients.展开更多

This study was conducted to evaluate CIM＇s effects on tumor infiltrating lymphocytes （TIL） and HLA-DR expression in tumor stroma in colorectal cancer （CRC）, so as to investigate its role in local immune response at the tumor site in CRC. Methods： Forty-nine CRC patients were randomized into treatment group of 25 patients who took CIM 7 days before curative surgery till the operation day, and control group of 24 patients who received similar treatment except for CIM intervention. TIL responses and HLA-DR expression were studied on tumor tissues taken before and after surgical resection. Results： The percentage of significant TIL response was increased from 32% （8/25） to 76% （19/25） （P〈0.005） in the CIM treatment group, whereas there were no significant changes in TIL response in the control group [25% （6/24） at recruitment vs. 33% （8/24） at operation, P〉0.50]. Moreover, the percentages of HLA-DR expression were increased from 36% （9/25） to 72% （18/25） in the CIM treatment group, but there were no significant differences in HLA-DR expression in the control group [41.7% （10/24） before resection vs 45.8% （11/24） after resection, P〉0.50]. Conclusion： CIM used before surgery might promote TIL responses and increase the HLA-DR expression in stroma cells in CRC patients, leading to enhanced host immunity against tumor.展开更多

We analyzed the relationship between the number of resected LNs with the 5-year survival, the recurrence rate and the post-operative complication rate.RESULTS: The 5-year survival of the entire cohort was 82.2%. The total number of dissected LNs was one of the independent prognostic factors. Among patients with comparable depth of invasion, the larger the number of resected LNs, the better the survival (P<0.05). A cut-point analysis provided the possibility to detect a significant survival difference among subgroups. Patients had a better long-term survival outcomes with LN counts ≥15 for pT1-2, ≥20 for pT3-4, and ≥15 for the entire cohort. The overall recurrence rate was 29.4% within 5 years after surgery. There was a statistically significant, negative correlation between the number of resected LNs and the recurrence rate (P>0.01). The post-operative complication rate was 10.9% and was not signif icantly correlated with the number of dissected LNs (P>0.05).CONCLUSION: For node-negative gastric cancer, sufficient number of dissected LNs is recommended during D2 lymphadenectomy, to improve the long-term survival and reduce the recurrence. Suitable increments of the dissected LN count would not increase the post-operative complication rate.展开更多
