| 目的 分析食管癌放疗患者近期疗效为完全缓解（CR）患者的治疗失败模式，并分析影响近期疗效的因素。方法 选取260例行根治性放疗的食管癌患者进行研究，分析治疗后的失败模式及影响患者近期疗效和预后的影响因素。结果 全组患者治疗后完全缓解（CR）91例（35.0%），部分缓解（PR）158例（60.8%），无缓解（NR）11例（4.2%）。患者性别（χ2=7.647，P<0.05）、T分期（χ2=33.548，P<0.05）、N分期（χ2=13.365，P<0.05）、TNM分期（χ2=27.792，P<0.05）、病变X射线长度（χ2=20.851，P<0.05）和大体肿瘤体积（GTV）（χ2=41.772，P<0.05）为近期疗效的影响因素。全组患者局部复发75例（28.8%），远处转移66例（25.4%），复发伴远处转移16例（6.2%）。复发患者1、3、5年生存率分别为71.4%、15.4%、7.7%，显著低于无复发患者的78.1%、43.2%、33.1%（χ2=23.330，P<0.05）；转移患者1、3、5年生存率分别为68.3%、12.2%、4.9%，显著低于无转移患者的79.2%、43.3%、33.1%（χ2=29.350，P<0.05）。治疗后达CR者出现复发/转移的比率显著低于PR者和NR者（χ2=11.248、20.301，P<0.05），CR总生存率、局部控制率、无远处转移生存率及无瘤生存率高于PR者和NR者（χ2=83.080、41.340、72.640、40.010，P<0.05）。T分期、N分期及近期疗效为独立性预后影响因素（HR=1.197、2.309、2.149，P<0.05）。结论 近期疗效为食管癌患者长期生存预后的影响因素，且与治疗后复发/转移密切相关，治疗后达CR者预后明显优于PR者及NR者。 |

| Objective To investigate the failure patterns for esophageal squamous cell carcinoma (ESCC) after radiotherapy and the influencing factors of recent efficacy. Methods 260 ESCC patients underwent radical radiotherapy and follow-up of 34.1 (6.2-105.2) months. The efficacy was observed to find locoregional recurrence and distant metastasis. Results Out of the 260 patients, 91 achieved complete remission (CR)(35.0%), 158(60.8%)achieved partial remission (PR),and 11(4.2%) achieved no remission (NR). Univariate analysis showed that gender(χ2=7.647,P<0.05), T stage(χ2=33.548,P<0.05), N stage(χ2=13.365,P<0.05), TNM stage(χ2=27.792,P<0.05), length of tumor(χ2=20.851,P<0.05), and gross tumor volume (GTV)(χ2=41.772,P<0.05)were the influencing factors for the recent efficacy. Locoregional recurrence was recognized in 75 patients, 66 patients showed distant metastasis alone, and locoregional recurrence accompanied with distant metastasis was observed in 16 patients. The overall survival rate of the recurrence/metastasis patients was significantly lower than that of the patients without metastasis/recurrence (χ2=23.330, 29.35,P<0.05). The recurrence/metastasis rate of the CR patients was significantly lower than that of the PR and NR patients respectively(χ2=11.248,20.301,P<0.05). The overall survival rate, local control rate, distant metastasis free survival rate, and disease-free survival rate of the CR patients were all significantly higher than those of the PR and NR patients respectively(χ2=83.080,41.340,72.640,40.010,P<0.05). Multivariate analysis showed that clinical T stage, clinical N stage, and recent curative effect were the independent influencing factors for the EC patients(HR=1.197, 2.309, 2.149,P<0.05). Conclusions Recent efficacy is the major influencing factor of the prognosis of ESCC, affecting the long-term survival of the patients after treatment, and closely related to the recurrence/metastasis as well. The prognosis of the CR patients is significantly better than that of both PR and NR patients. |
