Front Oncol:复发鼻咽癌患者挽救手术治疗的疗效:meta分析

2021-10-17 yd2015 MedSci原创

该荟萃分析表明,复发鼻咽癌患者挽救性手术有利于生存。准确评估肿瘤的复发分期和选择合适手术方式是成功关键。后期需要更多的随机对照研究去进一步证实。

鼻咽癌是一种发生于头颈部的恶性肿瘤,起源于鼻咽部上皮细胞。鼻咽癌的主要治疗策略是放疗加或不加化疗。大约7%至15%的患者在根治性放疗后仍有病灶残存或复发,10%至40%的患者在初次治疗后1至2年内复发。目前,对复发性鼻咽癌的管理还没有一个标准的治疗策略。手术是治疗复发性局部鼻咽癌的首选方法。调强放疗(IMRT)可以选择作为不可切除患者的一种挽救方式。近期,国内团队开展meta分析,评估复发性鼻咽癌挽救性手术治疗的效果。相关结果发表在Frontiers in Oncology杂志上。

最后筛选出21篇文章,其中17篇样本量大于10,纳入meta分析。10篇文章提供了详细的生存数据。

rNPC患者手术后联合或不联合辅助治疗的2年OS、5年OS和2年DFS为 71% (95% CI, 62%-80%, I 2 = 83.2%, p<0.05), 50% (95% CI, 34%-66%, I 2 = 94%, p<0.05)和61% (95% CI, 46%-75%, I 2 = 77.5%, p<0.05)。

 手术治疗预后

在亚组分析中,单独接受手术的患者2年OS率(72%,95% CI, 61%-83%, I 2 = 86.3%, p <0.05)比手术+辅助治疗患者的要好(64%,95% CI, 55%-73%, I 2 = 0.00%, p = 0.641)。术后辅助治疗组的5年OS率为44% (95% CI, 35%-52%, I 2 = 0.00%, p = 0.543), 单独手术治疗组为56% (95% CI, 31%-80%, I 2 = 96.9%, p<0.05)。术后辅助治疗组2年DFS为77% (95% CI, 52%-1.01%, I 2 = 77.5%, p<0.05),高于单纯手术组(54%,95% CI, 39%-70%, I 2 = 64.5%, p <0.05)。

   亚组分析

研究进一步比较了单纯手术治疗的患者,开放手术组的5年OS为77.0%,内镜手术组为82.5% (p>0.05);开放手术组2年DFS为85.0%,内镜手术组2年DFS为72.5% (p >0.05)。对于开放手术治疗患者,术后辅助治疗患者的5年OS率为35.2%,单纯手术组为77.0% (p>0.05);而2年DFS率分别为37.3%和85.0% (p < 0.05)。对于内镜手术治疗患者,术后辅助治疗患者的2年OS率为67.3%,单纯手术治疗患者的为82.5%(p,0.05)。

切缘状态、复发T期、辅助治疗影响患者的生存预后。在单变量中被认为有意义的变量被纳入Cox多变量分析。Cox多因素分析中,复发T期和辅助治疗是鼻咽癌复发DFS的独立危险因素。

                           预后相关因素

综上,该荟萃分析表明,复发鼻咽癌患者挽救性手术有利于生存。准确评估肿瘤的复发分期和选择合适手术方式是成功关键。后期需要更多的随机对照研究去进一步证实。

复发鼻咽癌治疗专家共识

随着IMRT应用,鼻咽癌LRC率取得明显提高,但仍有10%~15%患者出现复发。复发鼻咽癌的再程治疗一直是鼻咽癌治疗的难点。另外复发鼻咽癌的治疗方式多且每治疗方法各有优缺点,这也使得复发鼻咽癌的治疗更为困惑。由于目前尚缺乏高级别临床试验的证据指导,无法形成相应的治疗指南及规范。该共识对目前复发鼻咽癌治疗的相关文献和临床试验进行回顾,按复发鼻咽癌放疗、手术治疗及化疗靶向治疗等进行分层探讨和总结;对目
