对各期口腔鳞癌的治疗,目前五年生存率最高仅达50%,越是晚期,生存率越是显著减少。局部复发是治疗失败的主要标志。动脉灌注化学药物可使30—50%病例的肿瘤缩小,其中15%病例的肿瘤完全消退。现已证实,联合用药比单独用药效果好。放疗联合手术治疗比单独手术治疗效果好。区域灌注化学药物之后进行放疗可使肿瘤的消退增 For the treatment of oral squamous cell carcinoma of the various stages, the current five-year survival rate is only 50%, and the later the survival rate is significantly reduced. Local recurrence is the main sign of treatment failure. Arterial infusion of chemical drugs can shrink tumors in 30% to 50% of cases, and 15% of tumors completely disappear. It has been confirmed that the combined use of drugs is more effective than the use of drugs alone. Radiotherapy combined with surgical treatment is better than surgery alone. Radiotherapy after regional infusion of chemical drugs can lead to tumor regression
