Background

Recent reports have indicated that overexpression of mucin (MUC) 1 and/or MUC4 correlates with the occurrence and progression of extra-hepatobiliary malignancy. In this study, we investigated the expression of MUC1 and MUC4 and their prognostic significance in gallbladder adenocarcinoma.

Methods

We examined 54 surgical gallbladder adenocarcinoma samples by immunohistochemistry for MUC1 and MUC4 expression. Staining was evaluated as a sum score of extent and intensity, dividing the samples into low and high expression groups.

Results

The low expression group for both MUC1 and MUC4 was 10 samples (18.5%), and the high expression group was 44 samples (81.5%). High MUC1 expression was significantly correlated with more differentiated tumors (p=0.033), whereas high expression of MUC4 correlated with negative nodal status (p=0.012). Other pathological features were not correlated with MUC expression. Multivariate cox regression analysis showed that neither MUC1 nor MUC4 expression correlated with survival.

Conclusions

Although there were some correlations found, a prognostic role for either MUC1 or MUC4 expression in gallbladder carcinoma was not identified in this study. Further investigation is required.

Abstract: Alterations of the mucin-type glycoproteins may contribute to changes in cancer cell growth regulation, immune regulation, and cellular adhesion, which in turn may influence the invasive and metastatic capabilities of the cancer. Many of the cancer-associated antigens such as mucin antigens have been identified recently and alterations in the glycosylation of the mucins have been described in the cancer. Immunohistochemical studies of 3 antigens associated with alteration of the mucin glycoprotein (MUC1, MUC2, STn) were done to evaluate their relationship with known pathologic prognostic factors and their usefulness in assessment of the progression of gastric carcinoma in 127 gastric carcinoma tissues. The MUC1 was detected in 57 (44.9%), MUC2 in 76 (59.8%) and STn antigen in 77 (60.6%) out of 127 cases of gastric carcinomas. The expression rate of MUC1 was significantly correlated with depth of tumor invasion, lymph node and distant metastases, and advanced tumor stage (p=0.001). The expression rate of MUC2 was not significantly correlated with pathologic findings and known prognostic factors. The STn antigen was significantly associated with incidence of lymph node metastasis (p=0.02). The coexpression of both MUC1 and MUC2 or MUC1 and STn was more frequent in tumors with deep invasion, lymph node metastasis and advanced tumor stage than one or none expression (p<0.05). These results suggest that the alterations of expression of the mucin proteins, especially MUC1 and carbohydrate antigen (STn) are associated with poor biological behavior of the gastric carcinoma.

Abstract PDF: Background
: Differential diagnoses of intrahepatic adenocarcinomas (IHAC) play an important role in the detecting primary sites and the determining type of treatment and overall prognosis of the patient. However, histopathologic findings alone have limitations of differential diagnoses of IHAC. Methods : To clarify which tumor related proteins (TRP) are useful for differential diagnoses of IHAC, TRP expression were investigated immunohistochemically, using MUC5AC, MUC2, mAb 91.9H, MUC1, and pS2, and by high iron diamine (HID) staining in 61 clinically confirmed IHACs. Results : MUC5AC (9/18, p<0.05) and MUC1 (17/18, p>0.05) displayed the most frequent expression in cholangiocarcinomas, and MUC2 (11/18, p<0.05), mAb 91.9H (16/18, p<0.05), and HID (16/18, p<0.05) in colorectal adenocarcinomas. pS2 (3/11, p>0.05) was expressed more often in pancreatic adenocarcinomas than other IHAC, while MUC2 and 91.9H were not expressed at all in pancreatic adenocarcinomas. The positivity of several TRP did not correlate with tumor differentiation. Conclusions : MUC5AC, MUC2, mAb 91.9H, and HID may be useful in differentiating cholangiocarcinomas from colorectal adenocarcinomas.
