双原发肺癌外科治疗的疗效分析

目的 探讨双原发肺癌的外科治疗结局和长期生存率.方法 对1999年1月至2009年6月收治的98例双原发肺癌患者的临床资料进行回顾性分析.同时双原发肺癌患者共72例,其中男性54例,女性18例;发病中位年龄66岁.异时双原发肺癌患者26例,其中男性20例,女性6例;第一原发癌发病中位年龄59.5岁,第二原发癌发病中位年龄66岁.同时双原发肺癌患者72例,144个肿瘤病灶,手术方式包括肺叶切除9例,双肺叶切除14例,全肺切除6例,肺叶切除并楔形切除33例,双楔形切除9例,双肺叶切除并楔形切除1例;异时双原发肺癌患者26例,52个肿瘤病灶,手术方式包括肺叶切除31次,双肺叶切除1次,楔形切除10次,全肺切除8次.结果 全组患者术后30 d病死率为0,术后并发症发生率为13.3%.全组患者从术后开始随访至2009年12月,随访率＞90%.全组患者从发现第一原发癌开始计算,其5年生存率为66.4%.异时第一原发肺癌和同时双原发肺癌的5年生存率差异有统计学意义(96.2%比43.0%,P=0.000).异时第二原发肺癌和同时双原发肺癌的5年生存率差异无统计学意义(45.9%比43.0%,P=0.634).结论 外科手术治疗双原发肺癌是合理的,能使患者获得较高的长期生存预期.

Abstract：

Objective To verify the outcome and long-term survival of surgical management for double primary lung cancers. Methods The clinical data of 98 patients with double primary lung cancers admitted between January 1999 and June 2009 was analyzed retrospectively. There were 72 cases of synchronous double primary lung cancers, including 54 males and 18 females with median age of onset of 66 years (37 to 79 years). Thoracic surgical procedures for 144 tumor lesions included lobectomy for 9 cases, bilobectomy for 14 cases, pneumonectomy for 6 cases, lobectomy plus wedge resection for 33 cases, double wedge resection for 9 cases, and bilobectomy plus wedge resection for 1 case. There were 26 cases of metachronous double primary lung cancers, including 20 males and 6 females. The median age for the first primary cancer was 59. 5 years (38 to 73 years) , for second primary cancer was 66 years (47 to 77 years). Thoracic surgical procedures for 52 tumor lesions included lobectomy for 31 cases, bilobectomy for 1 cases, wedge resection for 10 cases, and pneumonectomy for 8 cases. Results The overall 30-day mortality was 0.Postoperative complications rate was 13. 3% . All patients were followed up after the operation. Until December 2009, follow-up rate was over 90%. Five-year survival for all the patients from the time of initial diagnosis of cancer was 66. 4%. Five-year survival for patients with metachronous and synchronous disease from the time of initial diagnosis of cancer was 96. 2% and 43. 0% ( P =0. 000) , respectively. Survival at 5 years for the second cancer of metachronous disease and synchronous disease was 45. 9% and 43. 0% (P =0. 634) ,respectively. Conclusion Surgical treatment for double primary lung cancer is reasonable, and the patients can make long-term survival.
