Expression and prognostic significance of MCM-3 and MCM-7 in salivary adenoid cystic carcinoma.

This study sought to investigate minichromosome maintenance protein 3 (MCM3) and minichromosome maintenance protein 7 (MCM7) expression in salivary adenoid cystic carcinoma (SACC) samples, and to evaluate the relationship between clinicopathological characteristics and prognosis. The expressions of MCM3 and MCM7 were evaluated using immunohistochemistry of tissue sections from SACC patients, and statistical analyses were performed to evaluate the associations between MCM expression and clinicopathological variables and to analyze the disease-free survival (DFS) and prognostic factors. The positive expression rates of MCM3 and MCM7 in SACC were 98.
