Clinicopathological analysis of oral and maxillofacial acinic cell carcinoma: A systematic review

다국어 초록 (Multilingual Abstract)

The aim of the present systematic review was to analyze the available data regarding acinic cell carcinoma of the oral and maxillofacial region.
A search strategy was performed using PubMed, Web of Science, Scopus, and Embase electronic databases.
Available data revealed a slight female preference (54.73%) and a mean age at diagnosis of 47.51 ± 19.85 years. The parotid glands (67.72%) were most frequently affected, and most cases were asymptomatic (69.54%). A microcystic histopathological pattern was reported in 21.56% of the cases, and the Periodic acid‐Schiff was the staining method most frequently used, after the hematoxylin and eosin staining, in the tumors analyzed. The lesions were mainly treated by surgical removal (72.32%). Recurrence was reported in 81 cases (27.83%) and metastasis in 100 (42.91%). Statistical data analysis revealed that tumors located in major salivary glands and exhibiting high‐grade histology were associated with local recurrence (P = .01). In addition, the patients older than 57 years, lesions with bone involvement, the high‐grade tumors and the cases with a history of recurrence and metastasis were associated with a lower overall survival (P < .05).
By assembling all eligible cases in the literature, the present systematic review determined the most common clinicopathological profile of acinic cell carcinoma and the most relevant prognostic factors in a distinctly representative sample. The survey demonstrated the importance of considering the histopathological grading in order to better define the treatment for each case.
