由于以往文献中所描述的口腔粘膜鳞状细胞癌多为T_2和T_3期有症状的肿瘤,因此作者对116例患者的222个初期、无症状的鳞状细胞癌进行广泛、深入的分析。结果表明,除15例发在下唇外,其余207个病变均在口内。其中201个病变(97.1%)发生在3个部位。口底(101个)、舌腹面和侧面(36个)、软腭(64个)。在口底病变中,73个(72.3%)病变发生在口底前方,其中33个累及颌下腺导管口乳头。187个病变(84.2%)在2厘米以下,其
Since most of the oral mucosal squamous cell carcinomas described in previous literature are symptomatic tumors of T2 and T3 stages, the authors conducted extensive and in-depth analysis of 222 early and asymptomatic squamous cell carcinomas in 116 patients. The results showed that except for 15 cases in the lower lip, the remaining 207 lesions were in the mouth. Of these, 201 lesions (97.1%) occurred in 3 sites. At the bottom of the mouth (101), lingual and ventral (36), soft palate (64). In the lesions at the bottom of the mouth, 73 (72.3%) lesions occurred in front of the floor of the mouth, and 33 of them involved the submandibular gland ductal papilla. 187 lesions (84.2%) were below 2 cm, which
