SMARCB1/INI1 Protein Expression in Round Cell Soft Tissue Sarcomas Associated With Chromosomal Translocations Involving EWS: A Special Reference to SMARCB1/INI1 Negative Variant Extraskeletal Myxoid Chondrosarcoma

Abstract excerpt

Several previous studies have demonstrated the lack of SMARCB1/INI1 protein expression in only the malignant rhabdoid tumor (MRT). Several sarcoma groups are associated with a tumor-specific translocation involving EWS. Moreover, the EWS and SMARCB1/INI1 genes are located on the same 22q chromosome. We analyzed the status of SMARCB1/INI1 protein expression in 93 cases of sarcomas associated with chromosomal...
