目的 评价全脑照射和同期脱氧氟尿苷 (FUDR) +鬼臼噻吩甙 (VM 2 6) +顺铂 (DDP)化疗方案治疗非小细胞肺癌 (NSCLC)脑转移的毒性及近期疗效。方法 FUDR 60 0mg/(m2 ·d) ,VM 2 660mg/(m2·d) ,DDP 2 0mg/(m2 ·d) ,均为第 1～ 5天 ,每 3～ 4周重复。全脑照射剂量为 3 0Gy ,每次 2Gy ,5次 /周 ,残瘤病灶≤ 3个时 ,行缩野剂量为 2 0Gy ;残瘤病灶≥ 3个时 ,继续全脑照射剂量为 10Gy。化疗与全脑放疗同期实施 ,放疗结束且同期化疗 2周期左右 ,行脑部CT或MRI评价疗效。结果 全组 3 0例患者均按计划完成全脑放射与同期化疗 ,其中 2 6例对残瘤病灶完成缩野治疗。化疗共完成 68周期 ,2 3例完成 2周期以上。随诊率93 .3 % ,中位生存期 11.3个月。化疗最常见的不良反应有骨髓抑制、胃肠道反应、便秘、脱发。在 68个周期中 ,Ⅲ +Ⅳ度白细胞降低占 19.1% ,贫血 10 .3 % ,血小板减少 7.4% ;胃肠道反应 4.4% ;脱发 5 .9%。全脑照射 2周左右时均需不同程度的脱水治疗。治疗后全组总缓解率为 46.7% ,其中CR 2例 ,PR 12例 ;脑部病灶总有效率为 60 .0 % ,其中CR 8例 ( 2 6.7% ) ,PR 10例 ( 3 3 .3 % ) ;全组未控肺部原发灶可评价化疗疗效者 2 2例 ,取得PR 4例 ( 18.2 % )。 2
Objective To evaluate the efficacy and toxicity of concomitant chemoradiotherapy in patients with brain metastases from non small cell lung cancer (NSCLC). Methods Thirty patients suffering from NSCLC with brain metastasis were prospectively included in this study. Twenty four patients had neurological symptoms and an ECOG performance index between 0 and 3. Treatment consisted of concomitant whole brain radiotherapy (WBRT) with a dose of 30 Gy in 15 fractions, followed by a local boosted dose of 20 Gy in 10 fractions for those that the number of the remained lesions were less than 3, or by WBRT with a total dose of 50 Gy for those that the number of the remained lesions were more than 3. Concomitant chemotherapy of FVP regimen with floxuridine 600 mg/(m 2·d), teniposide 60 mg/(m 2·d), cisplatin 20 mg/(m 2·d) on d1 to d5,repeating every 3 or 4 weeks. The response was evaluated by brain CT or MRI after WBRT and 2 cycles of chemotherapy being completed. Results All the patients completed WBRT and concomitant chemotherapy including 68 cycles (2 to 4 cycles for each patient). The follow up rate was 93.3% with a median survival duration of 11.3 months. Total response rate was 46.7%, with CR for 2 and PR for 12. Specific evaluation of brain response demonstrated CR for 8 patients, and PR for 10 patients (the objective brain response rate, 60.0% ). The objective primary disease response rate was 18% for 22 cases of previously untreated primary NSCLC. Other specific evaluation of metastases included 1 PR patient in 6 patients with lung metastases, 3 CR patients and 4 PR patients in 17 patients with lymph node metastases, 1 PR patient with liver metastases, and 1 PR patient with eye metastasis. Twenty four patients with neurological symptoms benefited improvements to different extent. The main adverse effects were myelotoxicity, nausea/vomiting, constipation and alopecia. Grade Ⅲ and Ⅳ toxicities were observed as following: leucopenia (19.1%), anemia (10.3%), thrombocytopenia (7.4%), nausea/vomiting (4.4%), diarrhea (2.9%), alopecia (5.9%), glutamio oxaloacetic transaminase (GOT) and glutamio pyruvic transaminase (GPT) elevation (1.5%). Dehydration therapy was needed at 2 weeks after WBRT in all patients. Conclusion Concomitant WBRT plus FUDR+VM 26+DDP chemotherapy is tolerable in NSCLC patients with brain metastases and the short term response is comparable to the results of others.
