Abstract
BACKGROUND AND OBJECTIVE: Brain metastases are common in non-small cell lung cancer. Usual treatments include radiotherapy and chemotherapy. However, these methods result in poor patient prognosis. The aim of this study is to assess the effectiveness of surgical resection in the multimodality management of non-small cell lung cancer patients with synchronous solitary brain metastasis. METHODS: The clinical data of 46 non-small cell lung cancer patients with synchronous solitary brain metastasis were retrospectively reviewed. All patients underwent surgical resection of primary lung tumor, followed by whole brain radiotherapy and chemotherapy. In addition, 13 out of the 46 patients underwent resection of brain metastasis, whereas the remaining 33 patients received stereotactic radiosurgery. RESULTS: The median survival time of the enrolled patients was 16.8 months. The 1-, 2-, and 3-year survival rates were 76.1%, 20.9%, and 4.7%, respectively. The median survival times of the patients with brain metastasis resection or stereotactic radiosurgery were 18.3 and 15.8 months, respectively (P=0.091,2). CONCLUSIONS: Surgical resection of primary lung tumor and brain metastasis may improve prognosis of non-small cell lung cancer patients with synchronous solitary brain metastasis. However, the survival benefit of surgical resection over brain metastasis resection or stereotactic radiosurgery is uncertain.

① 所有患者行肺部肿瘤手术切除(肺叶切除41例,全肺切除5例)。②脑转移瘤手术切除13例(肺部手术前3周-4周),SRS治疗33例(肺部手术前24例,肺部手术后9例)。③所有患者适时进行WBRT,放射源为6 MV或8 MV的χ射线,采用全脑两侧野对穿照射,放射剂量为30 Gy/10次/2周。④所有患者接受含铂方案的化疗,药物包括鬼臼噻吩甙、环己亚硝脲、长春瑞宾、吉西他滨、紫杉醇、多西他赛、培美曲塞等,中位化疗疗程5个周期(2-10周期)。⑤3例患者在放化疗后口服靶向药物治疗(易瑞沙2例,特罗凯1例)。
本组患者随访截止日期为2013年6月30日,其中死亡45例,存活1例。中位生存时间(median survival time, MST)为16.8个月(6.9个月-38.2个月),1年、2年和3年生存率分别为76.1%、20.9%和4.7%(图 1)。单因素分析显示生存期与患者的年龄、性别、PS评分、病理类型、肺部肿瘤的部位、肺癌术后T分期、N分期等均未见有相关性(P>0.05)。
