采用免疫组化染色，流式细胞术及体视学测量技术对38例肺癌标本进行LN表达、DNA含量及核面积均值测定，用多因素生存分析法分析这三种指标对肺癌患者生存期的影响。结果提示：多因素生存分析表明DI及核面积均值可作为肺癌患者的预后判断指标。
Immunohistochemical staining, flow cytometry and stereological measurement techniques were used to determine the expression of LN, DNA content, and nuclear area in 38 lung cancer specimens. Multivariate survival analysis was used to analyze the survival of patients with lung cancer. influences. The results suggest that multivariate survival analysis showed that DI and nuclear area mean values can be used as prognostic indicators for lung cancer patients.
