SQSTM1 and meningioma: Therefore, in the present paper, we have thought of interest to evaluate the immunohistochemical pattern of p62 in a large cohort of 133 low- and high-grade meningiomas, in order to verify if its expression may represent a linkage to autophagy, further revealing relationships with other clinicopathological data and achieving a prognostic role to predict the event of recurrence and/or invasion in meningiomas.
