Background Although the correlation between low claudin-1 expression and worse prognosis has been reported, details on the prognostic implications of claudin-1 expression in various malignant tumors remain unclear. The present study aimed to elucidate the prognostic roles of claudin- 1 immunohistochemistry (IHC) in various malignant tumors through a meta-analysis.
Methods The study included 2,792 patients from 22 eligible studies for assessment of the correlation between claudin-1 expression and survival rate in various malignant tumors. A subgroup analysis based on the specific tumor and evaluation criteria of claudin-1 IHC was conducted.
Results Low claudin-1 expression was significantly correlated with worse overall survival (OS) (hazard ratio [HR], 1.851; 95% confidence interval [CI], 1.506 to 2.274) and disease-free survival (DFS) (HR, 2.028; 95% CI, 1.313 to 3.134) compared to high claudin-1 expression. Breast, colorectal, esophageal, gallbladder, head and neck, and lung cancers, but not cervical, liver or stomach cancers, were significantly correlated with worse OS. Breast, colorectal, esophageal, and thyroid cancers with low claudin-1 expression were associated with poorer DFS. In the lower cut-off subgroup (< 25.0%) with respect to claudin-1 IHC, low claudin-1 expression was significantly correlated with worse OS and DFS.
Conclusions Taken together, low claudin-1 IHC expression is significantly correlated with worse survival in various malignant tumors. More detailed criteria for claudin-1 IHC expression in various malignant tumors are needed for application in daily practice.

BACKGROUND Pseudoepitheliomatous hyperplasia (PEH) is a reactive proliferation of surface epithelium and can be confused with invasive squamous cell carcinoma (SCC) in head and neck biopsy specimens. To distinguish PEH from invasive SCC, immunohistochemical staining for claudin-1, E-cadherin and p53 was performed. METHODS: Eighteen cases of PEH and 29 invasive SCC from head and neck lesions were immunostained and examined. RESULTS: The invasive SCC showed increased staining of claudin-1 (p<0.001) and p53 (p<0.001) and decreased staining of E-cadherin (p=0.005) compared to the PEH specimens. The combined score calculated by adding the positive sum of claudin-1 and p53 and subtracting E-cadherin was useful for the differentiation of SCC from PEH (89.7% sensitivity and 88.9% specificity, p<0.001). CONCLUSION: The combined immunostaining for claudin-1, p53 and E-cadherin may help differentiate PEH from invasive SCC. The results of this study suggest that the increased expression of claudin-1 and p53 and the decreased expression of E-cadherin maybe markers for the aggressive growth of invasive SCC.
BACKGROUND The claudins are a family of transmembrane proteins associated with tight junctions and they are critical for maintaining cell-to-cell adhesion in sheets of epithelial cells. However, their role in the progression of cancer remains largely unexplored. The aims of this study were to evaluate the expression patterns of claudin-1 and -4 in benign lesions and invasive ductal carcinomas (IDC) of the breast, and relationships between the expression of these markers and the clinicopathological characteristics in IDC patients. METHODS We examined the claudin-1 and -4 protein expressions by performing immunohistochemical stainings in 54 benign lesions and 120 IDCs via the tissue microarray method. We evaluated the correlation between the expression of these markers and the clinicopathological characteristics of IDC. RESULTS The expressions of claudin-1 (p=0.099) and -4 (p=0.000) were up-regulated in IDCs as compared with benign lesions. The claudin-1 expression correlated with the loss of estrogen receptor (p=0.036) and progesterone receptor (p=0.011). The claudin-4 expression correlated with lymph node metastasis (p=0.043), the nuclear grade (p=0.030), the histologic grade (p=0.007), and the loss of estrogen receptor (p=0.001) and progesterone receptor (p= 0.029). CONCLUSIONS These results suggest that claudin-1 and -4 may play a significant role in the carcinogenesis of IDC of the breast and these may represent novel markers for this disease.
