tested samples of MPLC with lymph node metastasis (LNM) and found that the genes with the highest mutation frequencies in this pair were MUC16, FLNA, MUC4, FAT3, SETD2, and CALR, which implied that MPLC with LNM may have a unique mutation spectrum (47). Here, MUC16 is linked to metastatic malignant neoplasm in the lymph nodes.
