恶性无功能性胰腺神经内分泌肿瘤手术策略与预后

目的探讨恶性无功能性胰腺神经内分泌肿瘤(PNETs)的临床病理特点、外科手术方式以及预后相关因素。方法回顾性分析37例经根治手术治疗的恶性无功能性PNETs患者的临床资料,包括性别、年龄、症状、肿瘤病理特点、手术方式及预后情况。根据手术范围将患者分为2组,即非扩大根治手术组(n=25)和扩大根治手术组(n=12)。2组计量资料比较采用t检验,计数资料比较采用Fisher精确检验,生存分析及单因素分析采用Kaplan-Meier法,组间生存率差异比较采用Log-rank检验,多因素分析采用Cox比例风险模型。结果 37例患者中,男性20例(54%),女性17例(46%),年龄28~72岁,中位年...

Summary:目的探讨恶性无功能性胰腺神经内分泌肿瘤(PNETs)的临床病理特点、外科手术方式以及预后相关因素。方法回顾性分析37例经根治手术治疗的恶性无功能性PNETs患者的临床资料,包括性别、年龄、症状、肿瘤病理特点、手术方式及预后情况。根据手术范围将患者分为2组,即非扩大根治手术组(n=25)和扩大根治手术组(n=12)。2组计量资料比较采用t检验,计数资料比较采用Fisher精确检验,生存分析及单因素分析采用Kaplan-Meier法,组间生存率差异比较采用Log-rank检验,多因素分析采用Cox比例风险模型。结果 37例患者中,男性20例(54%),女性17例(46%),年龄28~72岁,中位年龄48岁。21例(57%)肿瘤位于胰头部,16例(43%)肿瘤位于体尾部。根据WHO 2000年PNETs病理分类标准,高分化神经内分泌癌30例(81%),低分化神经内分泌癌3例(8%),混合性外分泌-内分泌癌4例(11%)。2组术后并发症发生率和住院时间差异无统计学意义(P〉0.05)。扩大根治手术组累计生存率、无瘤生存率也未显著低于非扩大根治手术组(P〉0.05)。多因素分析提示肝转移和Ki67是该组病例的独立预后影响因素。结论对于有胰周侵犯和肝转移的进展期恶性无功能性PNETs,积极的扩大根治手术是可行和合理的治疗方式。肝转移和Ki67是影响预后的独立危险因素。

Objective To investigate the clinical features, pathological characteristics, surgical strategies, and prognostic factors of malignant non-functioning pancreatic neuroendocrine tumors( PNET s). Methods The clinical records of 37 patients with malignant non-functioning PNET s who underwent curative surgery were retrospectively analyzed.The data included sex, age, symptoms, pathological characteristics, surgical strategies,and prognosis. Based on the extent of resection, patients were divided into two groups, i. e. the non-extended resection group( n = 25) and extended resection group( n = 12). T test was adopted to compare continuous variables. Fisher's exact test was used to compare categorical variables. Kaplan-Meier method
