近来人们越来越认识到舌癌的亚临床淋巴结转移问题,尤其是早期病变。现在更多的早期患者接受预防性颈淋巴清扫术,但这种治疗方案的确切效果尚有争议。本文回顾分析1970～1985年间MD.Anderson癌症中心收治的Ⅰ、Ⅱ期舌癌患者,旨在明确预防性颈淋巴清扫术与单纯舌切除相比,是否会提高区域控制率和生存率。 材料和方法 患者非随机性分为两组,第一组102 Recently, people are increasingly aware of subclinical lymph node metastasis of tongue cancer, especially early lesions. Now more early patients receive prophylactic neck dissection, but the exact effect of this treatment is controversial. This review analyzes the patients with stage I and II tongue cancer admitted to MD.Anderson Cancer Center from 1970 to 1985 to determine if prophylactic neck dissection improves regional control and survival compared with simple tongue resection.
