Abstract

This consensus statement was produced along with the gastric cancer discussions as stomach is the most common site for gastrointestinal stromal tumor (GIST). The recommendations apply to treatment of GIST.Evaluation of a patient with newly diagnosed GIST should include essential tests: A standard white light endoscopy with 6-8 biopsies (c-KIT testing on immunohistochemistry) from the tumor for confirmation of the diagnosis, a computed tomography (CT) scan (multi-detector or helical) of the abdomen and pelvis for staging with a CT chest or chest X-ray, and complete blood counts, renal function tests and liver function tests. Endoscopic ultrasonography (EUS)/magnetic resonance imaging (MRI)/positron emission tomography (PET)-CT are not recommended for all patients.For localized and resectable disease, surgery is recommended. The need for adjuvant treatment with imatinib would be guided by the risk stratification on the histopathological analysis of the resected specimen.For localized but borderline resectable tumors, upfront surgery may be considered only if complications due to the tumor are present such as major bleeding or gastric outlet obstruction. In all other patients, neoadjuvant imatinib should be considered to downstage the disease followed by surgery (with a curative intent, if feasible) in those with stable or partial response. This may be followed by adjuvant imatinib. In those patients with a poor response, further imatinib with dose escalation or sunitinib may be considered.Patients with metastatic disease must be assessed for treatment with imatinib as first-line therapy followed by sunitinib as second-line therapy versus best supportive care on an individual basis.
