TPF方案诱导化疗对局部N晚期鼻咽癌的近期疗效

Short-term effects of induction chemotherapy with one cycle TPF regimen in the N advanced local nasopharyngeal carcinoma

目的 比较1个疗程TPF方案和2个疗程PF方案作为诱导化疗对局部N晚期鼻咽癌的近期疗效和患者不良反应.方法 收集2007年1月至2008年12月初治的47例接受过诱导化疗的局部N晚期鼻咽癌患者,其中采用1个疗程TPF诱导化疗方案26例,采用2个疗程PF诱导化疗方案21例;唧方案使用多西紫杉醇（Docetaxel,TAX,商品名：泰素帝）60mg/m2,静脉滴注,第1天;顺铂（DDP）80mg/m2,静脉滴注,第1天;5-氟尿嘧啶（5-Fu）800mg/m2,第1天至第4天,静脉泵注.PF方案使用DDP 100 mg/m2,静脉滴注,第1天;5-Fu 1000 mg/m2,第1天至第4天,静脉泵注;两组均为3周方案.随后两组均采用DDP（30 mg/m2,每周方案）单药为基础的同期放化疗.观察比较两组患者的近期疗效和不良反应.结果 试验组诱导化疗后鼻咽部病灶有效率（CR＋PR）57.7%;颈部有效率69.2%,对照组2个疗程PF方案诱导化疗后鼻咽部病灶有效率66.7%;颈部有效率71.4%（P＆gt;0.05）.治疗后3个月试验组鼻咽部病灶和颈部淋巴结CR率分别为92.3%和88.7%,而对照组鼻咽部病灶和颈部淋巴结CR率分别为100.0%和90.5%（P＆gt;0.05）.试验组治疗不良反应主要是中性粒细胞减少和脱发.结论 1个疗程TPF诱导化疗对局部N晚期鼻咽癌可取得较好的局部控制率,中性粒细胞减少是主要的治疗毒性.

Objective To compare the short-term effects and toxicity of one cycle of TPF regimen induction chemotherapy with that of two cycles of PF regimen induction chemotherapy in the N advanced local nasopharyngeal carcinoma （NPC）. Methods A total of 47 patients initially treated with N advanced local NPC without distant metastasis from Jan 2007 to Dec 2008 were enrolled in this study. The TPF chemotherapy regimen was administered as follows： TAX 60 mg/m2, i.v. infusion on day 1st, cisplatin 80 mg/m2, i.v. infusion on day 1st and 5-Fu 800 mg/m2, bolus infusion in 96 hours on day lst-4th. The PF chemotherapy regimen was as follows： cisplatin 100 mg/m2, i.v. infusion on day 1 and 5-Fu 1000 mg/m2, bolus infusion in 96 hours on day lst-4th. Twenty-six patients received one cycle of TPF regimen and 21 patients received two cycles of PF regimen, with 21 days each cycle and a total of 3 courses in each group, then chemoradiotherapy with cisplatin 30 mg/m2 （weekly） was followed. Results The short-term efficacy was no significant difference between two groups, after one cycle TPF chemotherapy, the CR＋PR rates of primary site and lymph nodes were 57.7 % and 69.2 %, respectively, while after two cycles PF chemotherapy in control group, those were 66.7 % and 71.4 %, respectively （P〉0.05）. In 3 months after treatment, the CR rates of primary site and lymph nodes in TPF group were 92.3 % and 88.7 %, respectively, while those in control group were 100.0 % and 90.5 %, respectively （P〉0.05）. The main adverse reactions were Grade Ⅲ-Ⅳ neutropenia and alopecia in TPF group. Conclusion Short-term effects of induction chemotherapy with one cycle of TPF regimen in the N advanced local NPC is satisfied, and the main toxicity is neutropenia.
