JAMA:直肠癌患者:腹腔镜手术vs开腹手术

2015-10-09 Mechront 译 MedSci原创

目前对经腹腔镜行直肠癌切除术的有效性评价不一,尤其是晚期直肠癌。研究者进行了一项多中心双盲的随机对照试验,欲探究对于直肠癌患者行切除术,究竟是选择腹腔镜好,还是开腹手术更优,以大体标本和切除后组织结果作为评判。该研究于2008.10-2013.09在美国和加拿大的35个中心进行,共纳入486名临床分期为II、III期、距离肛门外源12cm以内的直肠癌患者,完成新辅助化疗后,随机分为腹腔镜组(n=2

目前对经腹腔镜行直肠癌切除术的有效性的评价不一,尤其是涉及到晚期直肠癌。研究者进行了一项多中心双盲的随机对照试验,欲探究对于直肠癌患者行切除术,究竟是选择腹腔镜好,还是开腹手术更优,本试验以大体标本和切除后组织结果作为评判。

该研究于2008.10-2013.09在美国和加拿大的35个中心进行,共纳入486名临床分期为II、III期、距离肛门外源12cm以内的直肠癌患者,完成新辅助化疗后,随机分为腹腔镜组(n=240)和开腹组(n=222)。

研究结果显示,腹腔镜组切除成功率为81.7%((95% CI, 76.8%-86.6%),开腹组切除成功率为86.9% (95% CI, 82.5%-91.4%);两组比较并不支持非劣性(difference,  −5.3%; 1-sided 95% CI, −10.8% to ∞; P = .41)。有11.3%的病人转为了开腹手术。腹腔镜组的手术时间明显长于开腹组(平均 266.2min vs 220.6 min; D 45.5 min; 95% CI, 27.7-63.4; P < .001)。以下情况相比较,两组间差异无统计学意义:住院时间(7.3 vs 7.0 d; difference,  0.3 days; 95% CI, −0.6 to 1.1);30天内再入院发生率(3.3% vs 4.1%; difference, −0.7%; 95% CI, −4.2% to 2.7%);严重并发症发生率(22.5% vs 22.1%; difference, 0.4%; 95% CI, −4.2% to 2.7%)。在93.5%的患者中,有77%的全直肠系膜切除完全,16.5%的近乎完全切除,但有遗留。总体来看,标本边缘病检阴性占90%,腹腔镜与开腹组分别为87.9%和92.3%。切缘远端病检阴性率超过98%,不管选择哪种方式。

研究结果表明,对于临床分为II、III期的直肠癌患者,与开腹行切除术相比,经腹腔镜手术在病理结果上未能达到非劣效性/等效性的标准。对临床肿瘤结果悬而未定的患者,以上研究结果不支持对该类患者经腹腔镜行切除术。

mFOLFOX6联合同期新辅助放疗治疗局部进展期直肠癌(FOWARC研究)

一项比较mFOLFOX6联合或不联合放疗新辅助治疗局部进展期直肠癌的多中心随机对照临床研究(FOWARC):初步结果。目的  局部进展期直肠癌的新辅助治疗标准方案是单药5-氟尿嘧啶(5-FU)联合放疗,但对远处转移控制不佳,增强化疗强度能否提高远处控制值得研究;另一方面,标准治疗影响患者的肛门功能和性功能,且术后的并发症发生率高,单纯新辅助化疗后选择性应用放疗也值得探索。本研究

Lancet Oncol:增加mFOLFOX6改善直肠癌患者预后

研究表明,对新辅助放化疗有病理学的完全响应的局部晚期直肠癌患者有着更好的预后。他们就可以接受更小规模的手术或者甚至是不需要手术而是采用观察。但是对新辅助放化疗有着完全响应的患者比例仍旧很低。对放疗的响应是有时间依赖性的。从放疗到手术间隔时间越长,则获得病理学完全响应的患者比例会越多。研究人员假设通过扩大新辅助疗法和延长放疗和手术之间间隔的时间使得全身性化疗更为有效。   研究人员在北
