Ⅳ期声门型喉癌的治疗与预后分析

背景与目的:Ⅳ期声门型喉癌预后较差。本研究探讨Ⅳ期声门型喉癌的治疗方式以及颈淋巴结转移、手术切缘情况对预后的影响。方法:收集88例Ⅳ期声门型喉癌的临床资料,回顾性分析不同治疗方式、有否颈淋巴结转移及手术切缘阴性和阳性患者的生存情况。结果:Ⅳ期声门型喉癌总的3、5年生存率分别为71.6%、63.0%;采用单纯手术、手术加术后放疗、化疗加放疗及手术加化疗治疗的患者,其生存率差异均无统计学意义(P=0.729);初治时有淋巴结转移的患者比初治时无淋巴结转移的患者预后差(P=0.015);无淋巴结转移的患者中有隐性淋巴结转移者与无隐性淋巴结转移者生存率差异均无统计学意义(P=0.474);手术切缘阳性者术后放疗与阴性者相比,其生存率差异均有统计学意义(P=0.016)。结论:N分期是影响Ⅳ期声门型喉癌患者预后的重要因素,初治有淋巴结转移者预后差。手术切缘阳性者术后放疗生存率低于手术切缘阴性者。

Treatment and prognosis of stage IV glottic laryngeal cancer

BACKGROUND & OBJECTIVE: The prognosis of stage IV glottic cancer is poor. This study was to explore the impacts of different treatment modalities, cervical lymph node status and surgical margin on the prognosis of stage IV glottic cancer. METHODS: Clinical data of 88 patients with stage IV glottic cancer were reviewed. The correlations of different treatment modalities, cervical lymph node status, and surgical margin to the prognosis of stage IV glottic cancer were analyzed. RESULTS: The overall 3-and 5-year survival rates of the 88 patients were 71.6% and 63.0%. There was no significant difference in survival rate among the patients received operation, operation plus postoperative radiotherapy, chemoradiotherapy, and operation plus chemotherapy (P=0.729). The overall survival rate was significant lower in patients with lymph node metastasis than in those without lymph node metastasis (P=0.015); for stage cN0 patients, there was no significant difference between the patients with and without occult lymph node metastasis (P=0.474). There was no significant difference between the patients with positive surgical margin and those with negative surgical margin (P=0.016). CONCLUSIONS: N stage is the important prognostic factor for stage IV glottic cancer. The prognosis of patients with lymph node metastasis is poor. The survival rate of the patients with positive surgical margin is lower than that of those with negative surgical margin.
