喉咽癌有50～80％经颈淋巴途径转移,这种转移多见于梨状窝和其它部位浸润性生长的肿瘤。当首次就诊时有60～75％喉咽癌已有颈淋巴转移,摘除的淋巴结病理学检查时38～50％病例确诊为无临床症状的转移。而颈部转移的数量、部位和性质对预后有直接关系。为此作者对340例原发性和继发性癌进行观察,其中男318,女性22,不到50岁的112例,50岁以上者228侧。按TNM分级病变范围如下:109例为T_3N_(0-1)M_0(Ⅲ期),231例为T_(3-4)N_(0-3)M_0(Ⅳ期),241例原发性肿瘤确诊为角化型鳞状细胞癌,87例为非角化型鳞状细胞癌,余12例为未分化癌。
Hypopharyngeal cancer 50 to 80% of the cervical lymph node metastasis, this metastasis more common in the pear-shaped nest and other parts of the invasive growth of the tumor. When the first visit when there are 60 to 75% of hypopharyngeal carcinoma of the neck lymph node metastasis, removal of lymph node pathology 38 to 50% of cases were diagnosed as clinically silent metastasis. The number of neck metastases, location and nature of a direct relationship between the prognosis. To this end the author of 340 cases of primary and secondary cancer were observed, of which 318 were male, female 22, less than 50 years old in 112 cases, 228 years of age over 50 years. The range of TNM grade was as follows: 109 cases were T_3N_ (0-1) M_0 (stage Ⅲ), 231 cases were T_ (3-4) N_ (0_3) M_0 (stage Ⅳ), 241 cases were diagnosed as primary tumors 87 were non-keratinizing squamous cell carcinoma and 12 were undifferentiated carcinoma.
