Various treatment options for advanced laryngeal cancer are discussed. Although no results of prospective studies are available, combined treatment of total laryngectomy and radiotherapy seems to offer the best locoregional control rates and maybe survival rates. This, however, results in the loss of natural voice. Radiotherapy alone (RA) will result, in unselected cases, in a local failure rate of approximately 50%. However, when the radiation schedule will be tailored to radiobiological parameters like potential doubling time of clonogenic cells local control may be enhanced. The choice of treatment may be related to known prognostic factors like severe airway obstruction, sex, tumorextension and involvement of neck nodes. Since in females and in patients with tumors confined to the glottic region only local control with RA is high, primary radiotherapy is advocated. For patients with severe airway obstruction or N2-3 neck nodes, locoregional control rates with RA are poor, so surgery combined with postoperative radiotherapy is advisable. For the remaining group of patients RA may be tested against combined treatment in a prospective trial.
本文讨论了晚期喉癌的各种治疗方案。尽管尚无前瞻性研究的结果,但全喉切除术联合放疗似乎能提供最佳的局部区域控制率,甚至可能提高生存率。然而,这会导致自然嗓音丧失。在未经选择的病例中,单纯放疗(RA)会导致约50%的局部失败率。然而,如果根据放射生物学参数(如克隆源性细胞的潜在倍增时间)调整放疗方案,局部控制可能会得到加强。治疗方案的选择可能与已知的预后因素有关,如严重气道阻塞、性别、肿瘤扩展和颈部淋巴结受累情况。由于女性患者以及肿瘤仅局限于声门区的患者采用RA进行局部控制的成功率较高,因此提倡首选放疗。对于有严重气道阻塞或N2-3颈部淋巴结转移的患者,RA的局部区域控制率较差,因此建议采用手术联合术后放疗。对于其余患者群体,可在前瞻性试验中将RA与联合治疗进行对比测试。
