Association of colorectal cancer and GIST tumors - A diagnostic and therapeutic challenge: A case report

Abstract

The association between colorectal cancer and gastrointestinal stromal (GIST) tumors is increasingly cited in medical literature as an argument in the plea for full exploration of patients with digestive malignancies. The coexistence of the two lesions is frequently diagnosed randomly, pre- or intraoperatively, and may raise diagnostic and therapeutic problems. We present a case of association of a recto-sigmoid junction cancer with a GIST gastric tumor with full imaging and anatomo-pathological description, as well as its surgical and oncological management. Pre-, intra- and postoperative histopathological examinations, correlated with immunohistochemical tests, are essential to determine the key points of the therapeutic strategic.

Keywords: Colorectal cancer, GIST tumors, surgical and oncologic management.
