声门型喉癌部分喉切除术后复发原因探讨及预防

目的：探讨声门型喉癌术后复发的原因，提出有效的防治措施。方法：对我院191年8月－2001年8月收的46例声门型喉癌部分喉切除术后复发病例进行回顾性分析，对原发肿瘤的部位、手术方式及复发肿瘤的部位进行了分析。结果：46例首次复发声门型喉癌病例中，局部复发32例，其中喉内第二原发病变致术后局部复发13例，占40．6％（13／32）。颈部复发14例，其中上颈部是颈部复发的重要部位，占42．9％（6／14）。喉内局部复发再次手术治疗后第2次复发的9例中，上颈部和局部复发仍是主要的复发部位，占55．6％（5／9）。结论：正确处理晚期声门型喉癌和喉内局部复发癌的上颈部淋巴结及正确认识声门型喉癌内第二原发病变并作相应的处理是降低声门型喉癌术后复发的重要措施。

Study of the causes of recurrence of patients with glottic cancer after partial laryngectomy

Objective:To study the causes of recurrence of patients with glottic cancer after partial laryngectomy and to propose some possible measures for the prevention of glottic cancer postoperative recurrence.Method:A retrospective review of consecutive 46 patients with recurrent glottic cancer after partial laryngectomy was conducted. The sites of primary tumors, the ways of operations and the sites of tumor recurrence were investigated.Result:Among 46 patients diagnosed with glottic cancer recurrence after partial laryngectomy, 32 cases were local recurrences and 14 were regional metastasis or local-regional recurrences. 13 cases of the second primary lesions in larynx were the cause of the failure and occupied 40.6% of all cases of local recurrences (13/32). In the regional metastasis, the commonest recurrent site was encountered in the upper neck. The upper neck metastasis or local recurrences were common in local recurrent cases treated by salvage surgery.Conclusion:It is very important for the prevention of glottic cancer recurrence after partial laryngectomy to properly manage the upper cervical lymph node in the advanced glottic cancers and the local recurrences in larynx and to know the relation of the postoperative recurrence of glottic cancer and the second primary lesions in larynx and carry out corresponding management.
