| Outline of Final Research Achievements |
Pathological diagnosis of pleural sarcomatoid mesothelioma is difficult, especially differentiating from pulmonary sarcomatoid carcinoma. In this study, We conducted a comprehensive gene expression analysis extracted from formalin-fixed paraffin embedded tissue by GeneChip technology. At the result, MUC4 mRNA expression in mesothelioma was significantly lower than that of carcinoma. The we analyzed MUC4 expression in sarcomatoid mesotheliomas and sarcomatoid carcinomas by immunohistochemistry. As the result, mesotheliomas showed no MUC4 expression, however, approximately 70% cases of sarcomatoid mesotheiomas show positive for MUC4 antibody. From these result, MUC4 might be useful for differential diagnosis between sarcomatoid mesothelioma and pulmonary pleomorphic carcinoma
