Abstract
Numerous studies referring to conventional chemotherapy for aggressive fibromatosis with the use of doxorubicin, cyclophosphamide, vincristin, vinblastine and other drugs have been published. Imatinib mesylate is a recently developed oral anticancer agent designed to selectively inhibit tyrosine kinases implicated in oncogenesis and it seems to represent a promising opportunity (also in first line) in the treatment of patients with advanced disease not candidate to prior surgery.
