Research Abstract

Pediatric SMARCB1/INI1 (INI1)-deficient tumors were able to be re-classified into the three groups: conventional type, atypical teratoid/rhabdoid (AT/R) type and small cell type. Activation in Akt-mTOR pathway was found more frequently in AT/R and small cell types than in conventional type. Meanwhile, in most cases of epithelioid sarcoma (ES) including both conventional and proximal types, the Akt-mTOR pathway was activated.
It is suggested that mTOR inhibition is a potential treatment option for AT/R and small cell types of pediatric INI1-deficient tumor and ES. ES and malignant rhabdoid tumor are suggested to be distinct tumor entities.
