  北京大学肿瘤医院邢宝才教授

对于结直肠癌肝转移患者而言,外科切除是肝转移的最佳治疗方式。然而,初始可切除以及转化后获得切除的肝转移仅占全部肝转移患者的35%~40%。60%~65%的肝转移不可切除患者一般采用全身系统化疗。近些年,肝转移的射频治疗越来越多地应用到不可切除肝转移的治疗中,但射频联合化疗的肝转移患者与单纯系统化疗相比是否有生存获益尚缺乏证据。

EORTC-40004研究比较了射频联合化疗组患者与单纯化疗组患者的生存情况。2012年报告的初步结果显示射频联合化疗组的无进展生存(PFS)优于单纯化疗组。此次ASCO报告了这项研究的长期随访结果,中位随访时间9.7年。研究结果显示,射频联合化疗组与单纯化疗组的中位生存时间分别是45.6个月和40.5个月,射频联合化疗组的生存明显优于单纯化疗组(P<0.01)。这项研究证明,射频联合化疗(±手术切除)可以为不能手术切除的肝转移患者的生存延长提供机会。

于肝转移切除后的残余肝体积必须大于30%,而很多多发的肝转移分布在不同的肝段,切除所有病灶会造成残余肝体积不足。射频的微创优势可在完全毁损肝转移灶的同时,保留更多的肝体积,使患者在达到R0治疗的同时保证正常的肝脏功能。40004研究中患者长期随访的结果提示,对于不可切除的肝转移患者,射频联合化疗的方法可使其又增加一种治疗选择。

研究简介(Abs 3501)

射频消融(RFA)联合化疗用于不可切除的结直肠癌肝转移(CRC LM): EORTC-NCRI CCSG-ALM Intergroup 40004 (CLOCC)一项随机Ⅱ期临床研究的长期生存结果

这项研究评价了全身化疗联合RFA局部治疗用于不可切除的CRC LM患者(病灶数>9且不合并肝外转移)的获益。之前已经报道了随访30个月的患者总生存(OS)和PFS(Ann Oncol. 23(10): 2619-26, 2012),现报告中位随访9.7年的OS结果。

研究于2002-2007年纳入119例患者,随机给予单纯化疗(59例)或化疗+RFA(60例),两组的化疗均为6个月的FOLFOX方案(奥沙利铂85 mg/m2、亚叶酸钙、5-FU)+贝伐珠单抗(自2005年10月起)。原先不可切除的病灶经过化疗转化为可切除后,单纯化疗组患者可行手术切除。主要目标为联合治疗组的30个月OS率>38%。次要终点是OS和PFS。

化疗+RFA组中,56例(93.3%)患者接受RFA,51例(85%)接受化疗;而单纯化疗组59例患者全部接受化疗。化疗+RFA组30个月OS率为61.7%,达到研究的主要终点。超出预期的是,单纯化疗组的30个月OS率也高达57.6%。中位随访9.7年后,92例患者死亡,其中单纯化疗组53例,化疗+RFA组39例,两组OS率有显著性差异(HR 0.58,P=0.01)。化疗+RFA组与单纯化疗组的中位OS期分别为45.6个月和40.5个月。这是前瞻性探索化疗联合RFA治疗不可切除的CRC LM患者疗效的首次研究,该研究提示RFA联合化疗相较于单纯化疗改善了患者的长期生存。
