早期喉癌手术治疗及放射治疗的疗效均较满意,二者治愈率近似,然放疗后可保留发音功能,故许多病人均愿采取放射治疗。但晚期喉癌放疗效果就显著降低,国内外均采取手术切除或手术与放疗综合治疗。我们自1964年元月至1974年12月底,应用单纯放疗、肿瘤剂量在3000rad以上者83例,其中76例属晚期(按国际抗癌协会分期属Ⅲ、Ⅳ期)占全部病例的91.6%,由于各种原因未作手术治疗,以下重点讨论晚期喉癌单纯放疗的效果及影响愈后的各种因素。
Early surgical treatment of laryngeal cancer and radiation therapy are satisfactory, the cure rate of the two is similar, but radiotherapy can retain the pronunciation function, so many patients are willing to take radiotherapy. However, the effect of radiotherapy for advanced laryngeal cancer was significantly reduced. Surgical resection or combined surgery and radiotherapy was performed at home and abroad. From January 1964 to the end of December 1974, we used simple radiotherapy and 83 cases of tumors with a dose above 3000 rad. Of these, 76 cases were advanced (according to the International Society for the Advancement of Cancer, Stages III and IV) accounted for 91.6% of all cases. Because there are no surgical treatments for various reasons, the following focuses on the effects of radiotherapy for advanced laryngeal cancer and the various factors that influence the outcome.
