MUC1 and carcinoma: In lymph node metastases, high cytoplasmic MUC1 expression is associated with adverse prognosis, reaching significance in univariate analysis for all carcinoma cells (Figure 4, cutoff 73.7%, p = 0.022) and solid structures (cutoff 75.7%, p = 0.013), but not for MIPs (p = 0.062) or cribriform structures (p = 0.306).
