Analysis of Clinicopathological Characteristics of Malignancy Patients with Membranous Nephropathy and Literature Review.

The clinical and pathological characteristics of MN patients with concomitant malignancy are different from those of IMN patients. Active screening for malignancy should be performed in non-PLA2R-positive elderly MN patients with a poor therapeutic response. Staining for MN target antigens in kidney and tumor tissues may be inconsistent, and the role of MN target antigens needs to be further explored.
