Clinicopathologic analysis of 2736 salivary gland cases over a 11-year period in Southwest China

Objective: To investigate the epidemiological and clinicopathological characteristics of salivary gland tumors in southwest China in order to provide data for clinical diagnosis and other similar research. Methods: Between March 2007 and December 2017, 2736 patients with salivary gland tumors were recruited, the clinical and pathological data were retrospectively analyzed. Results: A total of 2736 patients had a ratio of males to females of about 1.02:1. The ratio of benign to malignant tumors was 3.46:1. Pleomorphic adenoma and adenoid cystic carcinoma had 50.8% and 7.2%, respectively. About 65.4% tumors occurred in the parotid gland. There was no significant difference between the tumor in the left or right parotid and the use of cell phones. There were significant differences between gender and both the characteristics and locations of salivary gland tumors (p < .05). There were also significant differences between the pathological characteristics and location of the salivary gland (p < .05). Conclusions: The salivary gland benign and malignant tumors were more common in pleomorphic adenoma and adenoid cystic carcinoma, most occurred in the parotid gland. The minor gland tumors are lower than other parts of China. The incidence of parotid gland tumors is not related to the use of cell phones.
