接受选择性淋巴结照射的食管鳞癌患者预后和失败模式的分析

目的探讨接受选择性淋巴结照射(ENI)的食管鳞癌患者预后和失败模式。方法回顾性分析2005年1月至2012年12月河北医科大学第四医院收治的179例符合入组条件的食管鳞癌患者,分析肿瘤局部相关因素预测患者预后的价值,分析影响患者近期疗效、预后的影响因素,并对影响患者总生存率(OS)、无进展生存率(PFS)和复发的指标分别进行单因素和多因素分析。结果全组患者1、3、5年OS和PFS分别为77.1%、40.1%、26.0%和62.6%、30.6%、20.3%。多因素分析结果显示声音嘶哑、cN分期、cTNM分期、GTV-横径(GTV-D)和GTV-体积/长度(GTV-V/L)为影响患者OS的独立性影响因素(P<0.05);声音嘶哑、cTNM分期和近期疗效为影响患者PFS的独立性影响因素(P<0.05)。全组有75例(41.9%)患者出现复发,61例(34.1%)远处转移,其中19例(10.6%)为合并复发和远处转移。75例复发患者中64例(85.3%)患者为单纯食管复发,4例(5.3%)为单纯淋巴结复发,另7例(9.3%)患者为食管合并淋巴结复发。治疗后达完全缓解(CR)的63例患者中有18例患者出现复发,其中仅有2例患者出现淋巴结复发;logistic多因素分析结果显示患者周边组织/器官受侵、GTV-D和近期疗效为影响患者复发的独立性影响因素(P<0.05)。结论食管鳞癌患者接受ENI确实可行,其失败主要模式仍为食管复发;治疗前声音嘶哑、GTV-D和GTV-V/L较大、临床分期较晚和近期疗效不佳为患者预后较差的指标;肿瘤周边组织受侵、GTV-D和近期疗效是影响患者失败的独立性因素。

Prognosis and failure patterns of esophageal squamous cell carcinoma patients undergoing selective lymph node irradiation

Objective To investigate the prognosis and failure mode of patients with esophageal squamous cell carcinoma receiving selective lymph node irradiation (ENI). Methods A total of 179 eligible patients with esophageal squamous cell carcinoma were retrospectively analyzed. The prognostic value of tumor-related factors, the influencing factors of short-term curative effect and prognosis of patients, and the single and multi factor indexes of affecting the overall survival rate (OS), progression free survival rate (PFS) and recurrence of patients were analyzed.SPSS 19.0 software was used for statistical analysis. Results The 1,3- and 5-year OS of the whole group were 77.1%, 40.1% and 26.0%,respectively, and 1-,3- and 5-year PFS were 62.6%,30.6%,and 20.3%, respectively. Multivariate analysis showed that hoarseness, cN stage, cTNM stage, GTV-transverse diameter (GTV-D) and GTV-volume/length (GTV-V/L) were independent factors affecting OS (P<0.05). The sonar, cTNM staging, and short-term efficacy were independent factors affecting PFS (P<0.05).Recurrence occurred in 75 patients (41.9%) in the whole group, and 61 patients (34.1%) had distant metastases. Among them, 9 patients (10.6%) had both recurrence and distant metastasis. Of the 75 patients with recurrence, 64(85.3%) had simple esophageal recurrence,4(5.3%) had lymph node recurrence, and 7 (9.3%) had both. Recurrence occurred in 18 of the 63 patients who achieved CR after treatment. Only 2 patients had lymph node recurrence. Logistic multivariate analysis showed that the surrounding tissue/organ invasion, GTV-D and short-term were independent factors affecting the recurrence rate (P<0.05). Conclusions ENI is feasible in patients with esophageal squamous cell carcinoma, and the main mode of failure is esophageal recurrence. Pre-treatment sonar, larger GTV-D and GTV-V/L, more advanced clinical stage and poorer short-term efficacy are indicators of poor prognosis, while the peripheral tissue involvement, GTV-D and short-term efficacy are the independent factors that influence failure.
