目的

分析手术切除肺腺癌的临床病理特点及预后情况,探讨肺腺癌的预后因素。

方法

回顾性分析接受手术的109例肺腺癌患者的临床资料,将临床病理特点进行单因素分析,单因素分析有统计学意义的指标纳入多因素分析。

结果

109例肺腺癌患者的术后5年生存率为44.0%(48/109),COX回归单因素分析显示肿瘤大小(χ2=8.995,P=0.003)、淋巴结状态(χ2=12.727, P=0.000)、TNM分期(χ2=39.544,P=0.000)、残端有无癌残留(χ2=35.551,P=0.000)、PCNA表达情况(χ2=5.441,P=0.020)影响患者的生存时间。COX回归多因素分析显示肿瘤大小、TNM分期、支气管残端有无癌残留是肺腺癌的独立预后因素(P<0.05);术后辅助化疗是Ⅱ期和Ⅲ期患者的预后影响因素(χ2=11.299,P=0.001)。

结论

肿瘤大小、TNM分期高、外科手术切除不完全是肺腺癌预后差的重要影响因素;Ⅱ期和Ⅲ期患者能够从术后辅助化疗中获益。

Objective

To investigate the clinicopathological characteristics and prognosis of lung adenocarcinoma undergoing resection, and explore the its prognostic factors.

Methods

The clinical data of 109 cases of lung adenocarcinoma undergoing resection were retrospectively reviewed. Univariate analysis of clinicopathological characteristics was performed, and the statistically significant factors were included in multivariate analysis.

Results

For the 109 cases of lung adenocarcinoma, the overall 5-year survival was 44.0%(48/109). Univariate analysis revealed that tumor size(χ2=8.995, P=0.003), lymph node status(χ2=12.727, P=0.0000), TNM stage(χ2=39.544, P=0.000), surgical margin(χ2=35.551, P=0.000)and expression of PCNA(χ2=5.441, P=0.020) influenced survival time. Multivariate analysis indicated that tumor size, TNM stage, and surgical margin were independent prognostic factors of lung adenocarcinoma (P<0.05), and postoperative chemotherapy was prognostic factors of stageⅡ and Ⅲ lung adenocarcinoma(χ2=11.299, P=0.001).

Conclusion

Tumor size, higher TNM stage and positive surgical margin may be important factors of unfavorable prognosis of lung adenocarcinoma, and patients with stage Ⅱ and Ⅲ lung adenocarcinoma may gain benefits from postoperative adjuvant chemotherapy.
