The optimal treatment of stage ⅢA-N2 non-small cell lung cancer （NSCLC） remains controversial. Resultsof primary surgery alone are not satisfied. Surgery after induction chemotherapy yields better outcomes compared to resectiononly which has been widely accepted. Randomized studies show induction chemotherapy followed by either radiotherapy or surgery have approximately equivalent survival outcomes，significant improved survival can be achieved by combined surgery in selected patients. Low-grade N2，effective response and mediastinal downstaging after induction therapy，and successful complete resection by lobectomy，are good indications of surgery. Ideal treatments are approached base on theheterogeneity of N2 . Patients with bulky or fixed N2 disease should be considered for radical chemo-radiotherapy，and surgeryshould be a part of multi-modality management for patients with non-fixed，non-bulky，single-zone N2 disease. Further randomized trials of surgery added to multi-modality management in patients with multi-zone N2 disease should be taken in order to establish possible subgroups of patients might be benefitted more from the addition of surgery.
目的:比较常规放射治疗与放射治疗同期合并顺铂(PDD)加卡培他滨(CAP)治疗局部晚期鼻咽癌的有效性,同时评价此联合方式的安全性。方法:从2003年2月至2005年11月,78例局部晚期鼻咽癌患者(Ⅲ、Ⅳa,92分期)随机分为两组,放化疗组在放疗的第1、4、7周均用PDD+CAP各化疗一周期,PDD:20mg/m2,静脉滴注,连用5天;CAP:1000mg/m2,每天2次,连用14天,休7天;21天为一周期。两组放疗方法相同:鼻咽原发灶采用60Co外照射,颈部淋巴结引流区采用60Co前切线照射加深部X线垂直照射,鼻咽部剂量为65～70 Gy／6.5～7周,颈淋巴结转移灶剂量为65～70 Gy／6.5～7周。结果:放化疗组及单放组治疗结束后3个月鼻咽部肿瘤完全消退率分别为89.7%,69.2%(P﹤0.05)。3年生存率分别为76.9%,53.8%(P﹤0.05)。结论:顺铂加卡培他滨方案联合放化疗治疗局部晚期鼻咽癌可改善患者的生存,毒副反应可耐受。
