Results: The PCNA mean labelling index was 48.84％± 13.63％, and the apoptotic labelling index was12.26‰± 5.20‰. The Kaplan-Meier survival curves showed that the postoperative survival time of the patient was shorter when the tumor infiltrated to the adventitia of esophagus,with lymph node metastasis, without keratinization, PI ≥ 40％ or AI＜10‰. Using forward multivariate Cox regression analysis, only the parameters of pN category and PI could be verified as independent prognostic factors.

结果：36例手术切除的食管鳞癌组织平均PCNA表达指数(PCNAlabellingindex，PI)为48.84％±13.63％，细胞凋亡指数(apoptosisindex，AI)为12.26‰±5.20‰；PI升高与患者年龄小、分化程度低、有淋巴结转移和肿瘤进行性浸润呈正相关，而AI升高与分化程度高、角化明显呈正相关；绘制Kaplan－Meier生存曲线，发现病变侵及食管外膜、有淋巴结转移、无角化、PI≥40％或AI＜10‰的患者术后生存率明显降低；COX比例风险模型分析，发现只有淋巴结转移和PI是影响预后的独立因素。

Univariate and multivariate analyses were performed with the logistic likelihood ratio test and the Cox proportional hazards model, respectively.

分别采用对数似然比检验和Cox比例风险模型进行单变量和多变量分析。
