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
