为探讨40岁以下年轻人舌鳞状细胞癌患者的临床特征及预后情况，作者采用病例对照研究，与同期中老年组患者进行比较分析，结果发现，年轻组患者中①农村来源的病人占有相当大的比例（69．2％，P＜0．01）；②女性病人所占的构成比相对较大（1：1．17，P＜0．05）；③颈淋巴结转移阳性率较高（42．4％，P＜0．05）；④术后一年内的复发率及死亡率均较中老年组高（分别为45．5％、38．2％，P＜0．05）。提示年轻人舌鳞癌可能与生活状况等因素有关，预后较差，须注意手术切除范围并加强术后随访。
To investigate the clinical features and prognosis of squamous cell carcinoma of the tongue in young people younger than 40 years old, the author used a case-control study to compare with the middle-aged and elderly patients in the same period. The results showed that in the young group, (69.2%, P <0.01); ② The proportion of female patients was relatively large (1: 1.17, P <0.05); ③ The positive rate of cervical lymph node metastasis was high 42.4%, P <0.05). The relapse rate and mortality in one year after operation were higher than those in middle-aged and elderly patients (45.5% and 38.2%, P <0.05, respectively). Tip young tongue squamous cell carcinoma may be related to living conditions and other factors, the prognosis is poor, we should pay attention to the scope of surgical resection and to enhance postoperative follow-up.
