肿瘤分化的高低往往取决于观察手术标本中肿瘤分化较差部分棘细胞形成的程度、角化情况以及瘤细胞与正常鳞状上皮细胞的近似程度,并将肿瘤分为分化好、中、差三型。临床上采用这种方法来衡量肿瘤的恶化程度。分化越高者治疗后局部复发、淋巴或血道转移的机会越少;这种 The level of tumor differentiation is often determined by observing the extent of prickle cell formation, keratinization, and the similarity of tumor cells to normal squamous epithelial cells in the poorly differentiated tumors of the surgical specimens, and dividing the tumors into well-differentiated, intermediate, and poorly differentiated tumors. type. This method is used clinically to measure the degree of deterioration of the tumor. Patients with higher differentiation have less chance of local recurrence, lymphatic or hematogenous metastasis after treatment;
