MUC1 expression was related to tumor location (high for oral side, p = 0.019), invasion depth (higher for deeper than pSS (pT3), p = 0.017), venous invasion (high for positive venous invasion, p = 0.038), and curability (high for non-curative resection, p = 0.007). This evidence concerns the gene MUC1 and neoplasm.
