| 摘 要： | 目的 比较诱导化疗联合同期放化疗与同期放化疗治疗局部晚期鼻咽癌(LA-NPC)的临床结果及探讨预后因素。 方法 分析2005年1月至2006年12月本院收治的433例无转移LA-NPC患者的临床资料, 按是否行诱导化疗分为诱导化疗联合同期放化疗组(A组)209例与同期放化疗组(B组)224例。采用Kaplan-Meier法进行生存分析, 差异比较采用Log-Rank法双侧检验, 预后因素分析采用Cox模型。 结果 A组、B组的3年总生存率(OS)、无局部区域复发生存率(LR-FFS)、无远处转移生存率(D-FFS)、无瘤生存率(FFS)分别为87% vs. 88%、95% vs. 95%、85% vs. 85%、81% vs. 81%;A组、B组的5年OS、LR-FFS、D-FFS、FFS分别为80% vs. 82%(P=0.503), 95% vs. 93%(P=0.673), 82% vs. 82%(P=0.992), 78% vs. 77%(P=0.851)。两组生存差异无统计学意义, 对于Ⅲ期鼻咽癌, A组FFS优于B组(P=0.075)。多因素分析显示老年、临床分期晚、颅神经侵犯、贫血、N分期晚为OS、D-FFS的独立不良预后因素。 结论 与同期放化疗相比, 诱导化疗联合同期放化疗未提高LA-NPC的OS、LR-FFS、D-FFS及FFS, 但具有改善Ⅲ期鼻咽癌FFS的趋势。诱导化疗联合同期放化疗不是鼻咽癌的必选治疗模式。

| Abstract: | Objective This study was aimed to make a comparison between induction chemotherapy followed by concurrent chemoradiotherapy and simple concomitant chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma(LA-NPC). It also aims to investigate prognostic factors. Methods Between January 2005 and December 2006, clinical data of 433 cases of non-metastatic LA-NPC undergoing initial treatment were collected and retrospectively analyzed. The patients were divided into Group A(209 cases) and Group B(224 cases). Group A underwent induction chemotherapy with concurrent chemoradiotherapy, whereas Group B underwent concomitant chemoradiotherapy alone. Kaplan-Meier method was employed for survival analysis. Log-rank test was used to analyze the statistical significance in the differences among the survival curves. A multivariate analysis with Cox proportional hazards model was used to test the independent prognostic factors. Results This study showed that the three-year overall survival(OS) rates were 87% and 88%, with the locoregional failure-free survival(LR-FFS) rates of 95% and 95%, distant failure-free survival(D-FFS) rates of 85% and 85%, and failure-free survival(FFS) rates of 81% vs. 81% in Groups A and B, respectively. The five-year OS rates were 80% and 82%(P=0.503), with LR-FFS rates of 95% vs. 93%(P=0.673), D-FFS rates of 82% vs. 82%(P=0.992), and FFS rates of 78% vs. 77%(P=0.851) in Groups A and B, respectively. Median follow-up was 61.1 months(ranging from 12.0 months to 75.7 months). No statistical differences were observed in the survivals between the two groups. However, improved FFS rate was observed for stage Ⅲ disease, which favors Group A(P=0.075). Multivariate analysis also showed that old age, advanced clinical stage, cranial nerve involvement, decreased hemoglobin, and advanced N stage were the independent adverse prognostic factors for both OS and D-FFS. Conclusion Induction chemotherapy followed by concurrent chemoradiotherapy did not improve OS, LR-FFS, D-FFS, or FFS for LA-NPC, compared with concurrent chemoradiotherapy alone. However, induction chemotherapy followed by concurrent chemoradiotherapy showed a trend of improved FFS for stage Ⅲ disease favoring Group A. Thus, neoadjuvant chemotherapy combined with concomitant chemoradiotherapy is not the necessary choice in managing LA-NPC. |
