JAMA Surg:老年结直肠癌手术治疗整体下降,死亡率也在减少

2014-04-28 MedSci MedSci原创

老年患者结直肠癌切除术死亡率和发病率的数据是相对缺乏的。刚刚在JAMA Surgery发表一项基于全国的大型队列研究中,Jafari等发现老年患者结直肠癌切除术整体数量下降,住院期间死亡率有所改善,尽管风险校正死亡率和发病率仍显著高于年轻患者。研究对2001年1月至2010年12月健康保健费用和应用计划全国住院患者样本中1043108例结直肠癌患者的手术预后进行了数据分析。对45-64岁、65-6

老年患者结直肠癌切除术死亡率和发病率的数据是相对缺乏的。刚刚在JAMA Surgery发表一项基于全国的大型队列研究中,Jafari等发现老年患者结直肠癌切除术整体数量下降,住院期间死亡率有所改善,尽管风险校正死亡率和发病率仍显著高于年轻患者。研究对2001年1月至2010年12月健康保健费用和应用计划全国住院患者样本中1043108例结直肠癌患者的手术预后进行了数据分析。对45-64岁、65-69岁、70-74岁、75-79岁、80-84岁和≥85岁年龄分组的术后并发症和每年趋势进行了分析。

应用多变量logistic回归分析来比较≥ 65岁组和45-64岁组患者的住院期间死亡率和发病率,并对性别、并存病、术式、诊断和住院期间状态进行控制。主要结果评估是住院期间死亡率和发病率。

手术率

在所有的患者中,63.8%的手术发生在≥ 65岁组,22.6%的手术发生在≥80岁组。在10年期间,切除术的数量在总体人群中平均每年下降了5.1%,在≥ 65岁组每年下降7.0%,在70-79岁组下降最大(7.5%)。

≥85 岁组患者紧急入院率(50.4%)是年轻患者的1.7倍——45-64岁组为29%,65-69岁组为29.6%,70-74岁组为31%,75-79岁 组为34%,80-84岁组为39%。< 65岁组择期腹腔镜手术占46.0%,≥ 80岁组则为14.1%。

死亡率和发病率

总 体上,住院期间死亡率为3.0%,其中45-64岁组最低(1.3%),≥85岁组最高(8.0%);65-69岁组为2.0%,70-74岁组为 2.9%,75-79岁组为3.7%,80-84岁组为4.9%。10年间死亡率每年下降6.6%,≥85岁组下降9.1%,80-84岁组下降 6.4%,75-79岁组下降7.5%,65-69岁组下降7.7%,45-64岁组下降1.7%。

多 变量风险校正分析,与45-64岁组患者相比,65-69岁组患者(比值比[OR]=1.32, 95%可信区间[CI]=1.18-1.49)、70-74岁组患者(OR=2.02, 95% CI=1.82-2.24)、75-79岁组患者(OR=2.51, 95%CI=2.28-2.76)、80-84岁组患者(OR=3.15, 95%CI=2.86-3.46)、≥ 85岁组患者(OR=4.72, 95%CI=4.30-5.18)的住院期间死亡率显著更高(P < .01)。

45-64岁组住院期间发病率为 27.4%,65-69岁组为32.2%,70-74岁组为34.9%,75-79岁组为37.2%,80-84岁组为40.0%,≥ 85岁组为44.9%。与45-64岁组患者相比,65-69岁组患者(OR=1.25, 95% CI=1.21-1.29)、70-74岁组患者(OR=1.40, 95% CI=1.36-1.45)、75-79岁组患者(OR=1.54, 95%CI=1.49-1.58)、80-84岁组患者(OR=1.68, 95%CI=1.63-1.74)、≥ 85岁组患者(OR=1.96, 95%CI=1.89-2.03)的住院期间发病率显著更高(P < .01)。

与45-64岁组患者住院期间费用($47,395)和住院时间(9天)相比,≥ 85岁组患者住院期间费用更高($58,863),住院时间更长(12天)。与< 65岁组患者相比,≥ 80岁组患者的费用增加$9,492,住院期延长2.5年。

上述结果能显示,老年患者结直肠癌手术的近期趋势包括每年切除术数量减少和住院期间死亡率降低。高龄仍然与住院期间高死亡率和发病率有相关性。

总结

大多数的结直肠癌手术发生在老年人群,接受手术的病例整体数量减少。尽管在过去的10年间整体死亡率有所改善,老年患者的风险校正死亡率和发病率比年轻组患者仍然要高很多。

来自中山大学肿瘤防治中心的研究人员证实,小分子miR-214通过调控FGFR1的表达负向调控了结直肠癌肝转移。这一重要研究发现已被在国际著名肝脏疾病杂志Hepatology(最新影响因子12.003)接受并在线发布。 中山大学肿瘤防治中心副主任徐瑞华(Rui-hua Xu)是这篇论文的通讯作者。徐教授长期从事肿瘤内科治疗(化学治疗、靶向治疗)的临床工作及抗癌药物研究。
