JAMA Surg:原发肿瘤切除术或不能提高Ⅳ期结直肠癌生存率

2015-01-26 王姗编译 中国医学论坛报

一项美国回顾性研究显示,1988年~2010年间,大多数Ⅳ期结直肠癌(CRC)患者曾接受过原发肿瘤切除手术,而自2001年起,原发肿瘤切除手术的临床使用逐渐减少,但患者生存率较前改善。随着化疗药物及生物制剂的不断问世,CRC原发肿瘤切除手术或已不再是常规治疗方式。论文1月14日在线发表于《美国医学会杂志·外科学》(JAMA Surg)。 研究纳入美国国立癌症研究所CRC监测、流

一项美国回顾性研究显示,1988年~2010年间,大多数Ⅳ期结直肠癌(CRC)患者曾接受过原发肿瘤切除手术,而自2001年起,原发肿瘤切除手术的临床使用逐渐减少,但患者生存率较前改善。随着化疗药物及生物制剂的不断问世,CRC原发肿瘤切除手术或已不再是常规治疗方式。论文1月14日在线发表于《美国医学会杂志·外科学》(JAMA Surg)。

研究纳入美国国立癌症研究所CRC监测、流行病学及转归注册系统中1988年~2010年间被诊断为Ⅳ期CRC、接受或未接受过原发肿瘤切除手术的64157例患者数据,分析随时间推移而出现的原发肿瘤切除率及相对生存中位值的变化。

结果为,67.4%的患者接受过原发肿瘤切除术。1988~2010年,原发肿瘤切除率由74.5%降至57.4%(P<0.001),且1998~2001年与2001~2010年之间存在显著的年百分比变化(-0.41%对-2.39%,P<0.001)。与原发肿瘤切除相关的因素包括年龄大于50岁、女性、已婚、肿瘤级别高以及结肠肿瘤。患者中位相对生存率在1988年为8.6%,在2009年增长至17.8%(P<0.001),1988~2001年与1996~2009年的年百分比变化分别为2.18%和5.43%(P<0.001)。
