Imatinib : A Breakthrough of Targeted Therapy in Cancer

الملخص EN

Deregulated protein tyrosine kinase activity is central to the pathogenesis of human cancers.

Targeted therapy in the form of selective tyrosine kinase inhibitors (TKIs) has transformed the approach to management of various cancers and represents a therapeutic breakthrough.

Imatinib was one of the first cancer therapies to show the potential for such targeted action.

Imatinib, an oral targeted therapy, inhibits tyrosine kinases specifically BCR-ABL, c-KIT, and PDGFRA.

Apart from its remarkable success in CML and GIST, Imatinib benefits various other tumors caused by Imatinib-specific abnormalities of PDGFR and c-KIT.

Imatinib has also been proven to be effective in steroid-refractory chronic graft-versus-host disease because of its anti-PDGFR action.

This paper is a comprehensive review of the role of Imatinib in oncology.
