ABSTRACT

Computed tomography is a tool that has proven useful in monitoring gastrointestinal stromal tumors subjected to targeted therapy.
Objective: evaluate by tomography the response to targeted therapy if gastrointestinal stromal tumors in patients at the Siglo XXI Cancer Hospital, in accordance with Choi’s criteria.
Materials and methods: a retrospective study, from January 2009 through January 2014, of patients with confirmed diagnosis of gastrointestinal tumor, who also had tomographies; response to treatment was analyzed in accordance with Choi’s criteria.
Results: 31 patients were included, 61% received targeted therapy with imatinib and 38% imatinib and sunitinib as second line therapy, with follow-up of at least 6 months and at most annual. In accordance with Choi’s criteria, in 45.2% the response was complete, in 19.4% there was stable disease, in another 19.4% partial response, and in 16.1% progression of disease.
Conclusions: Choi’s criteria proved to be useful in evaluating treatment with targeted molecular therapy in patients with gastrointestinal stromal tumors.
