MUC1 and neoplasm: [85] found that overexpression of MUC1 in patients with RCC was statistically significant in tumor size, distant metastasis, and large vein invasion (P < 0.05), and that expression of neoglycosylation epitopes exposed by MUC1 glycosylation insufficiency showed statistically significant differences in tumor recurrence, metastasis, and lethality (P < 0.001).
