Whether mucoepidermoid carcinoma of the parotid gland is curable in its early stages is related to its degree of differentiation. Highly differentiated individuals have low malignancy, and lowly differentiated individuals have high malignancy. According to the analysis of clinical data, the five-year postoperative survival rate is about 92% for highly differentiated and 49% for lowly differentiated.
Mucinous epidermoid carcinoma is the most common malignant tumor of salivary glands in clinic, which is classified into two major categories, highly differentiated and lowly differentiated, according to the proportion of mucinous cells, cell division, the number of mitotic elephants, and the growth mode of the tumor. The biological behavior and prognosis of the tumors vary according to the degree of differentiation.
Highly differentiated mucoepidermoid carcinoma of parotid gland has low malignancy, low cervical lymph node metastasis and even less hematogenous metastasis, with a five-year postoperative survival rate of about 92%; low-differentiated tumors are often adherent to the surrounding tissues, with unclear boundaries, high cervical lymph node metastasis, and hematogenous metastasis, which is prone to recurring after surgery, with a five-year survival rate of about 49%.
Those who find discomfort in the parotid gland should consult a doctor in time, improve the examination, make a clear diagnosis, and standardize the treatment under the guidance of a professional physician, so as not to delay the condition.
