摘要
目的 探讨术前体重减轻对胃癌患者生存预后的影响.方法 回顾性分析2003年1月至2007年12月收治的672例胃癌手术患者的临床病理资料,根据体重减轻百分比将所有患者分为:无体重减轻组(0%)、轻度体重减轻组(<10%)和重度体重减轻组(≥10%).比较三组患者的临床病理特点,分析体重减轻对预后的影响,采用Kaplan-Meier法计算生存率,单因素多因素分析均采用Cox回归模型.结果 本组672例胃癌患者中,无体重减轻组275例(40.7%),轻度体重减轻组294例(43.8%),重度体重减轻组103例(15.3%).三组患者在肿瘤大小(F =4.386)、肿瘤部位(x2=15.864)、浸润深度(x2=22.245)、淋巴结转移数(x2=23.803)、手术方式(x2=18.423)、清扫范围(x2 =8.172)、手术根治度(x2=15.650)间比较差异有统计学意义(均P<0.05).患者中无体重减轻组、轻度体重减轻组和重度体重减轻组患者5年生存率分别为45.9%、37.7%和28.0%,三组之间差异有统计学意义(x2 =20.148,P <0.05).年龄(95% CI:0.480 ~0.744,P=0.000)、术前体重减轻(95%CI:0.371~0.687,P=0.000)、浸润深度(95%CI:0.289~0.564,P=0.000)、淋巴结转移(95%CI:0.451 ~0.783,P=0.000)、清扫范围(95%CI:0.647 ~0.990,P=0.000)、根治度(95% CI:0.291~0.486,P=0.000)、辅助化疗(95%CI:0.511 ~0.846,P=0.000)与本组胃癌患者预后相关.多因素分析结果示年龄(HR=1.618,95%CI:1.298 ~2.016,P=0.000)、术前体重减轻(HR=1.258,95%CI:1.077 ~1.469,P=0.004)、浸润深度(HR=1.810,95%CI:1.287 ~2.545,P=0.000)、淋巴结转移数目(HR=1.555,95%CI:1.413 ~1.172,P=0.000)是该组患者的独立的预后因素.结论 术前体重减轻10%以上者预后差,术前体重减轻可能是胃癌患者的一个独立预后因素.
Objective To elucidate the prognostic influence of preoperative weight loss for gastric cancer.Methods A total of 672 gastric cancer patients who underwent gastrectomy between January 2003 and December 2007 were enrolled.The patients were categorized into three groups according to the percentage of weight loss before surgery:no weight loss group(0%),limited group (< 10%),and severe group (≤ 10%).Compared the clinicopathologic characteristics and analyzed the prognostic influence of preoperative weight loss.The survival was analyzed by Kaplan-Meier survival cure and the prognostic factors were analyzed univariately and multivariately by Cox comparative hazard modal.Results Among the 672 cases gastric cancer,no weight loss group had 275 cases,limited group 294 cases,severe group 103 cases.Tumor size(F =4.386),tumor location (x2 =15.864),depth of invasion (x2 =22.245),the number of lymph node metastasis (x2 =23.803),Surgical approach (x2 =18.423),extent of lymphadenectomy(x2 =8.172),curability(x2 =15.650) were discrepant among the three groups(all P < 0.05).The 5-year survival rate of the patients with severe group was 28.0%,limited group was 37.7%,while the no weight loss group was 40.3 % (x2 =20.148,P < 0.05).Age (95 % CI:0.480-0.744,P =0.000),weight loss before surgery (95% CI:0.371-0.687,P =0.000),depth invasion (95% CI:0.289-0.564,P =0.000),lymph node metastasis (95 % CI:0.451-0.783,P =0.000),extent of lymphadenectomy (95 % CI:0.647-0.990,P =0.000),curability (95 % CI:0.291-0.486,P =0.000),postoperative adjuvant chemotherapy (95 % CI:0.511-0.846,P =0.000) were associated with survival of this group.In multivariate analysis,age (HR =1.618,95% CI:1.298-2.016,P =0.000),weight loss before surgery (HR =1.258,95% CI:1.077-1.469,P =0.004),depth of invasion (HR =1.810,95% CI:1.287-2.545,P =0.000),N stage (HR =1.555,95 % CI:1.413-1.172,P =0.000) were independent pr
