To describe the computed tomographic (CT) appearances and clinical consequences of tumor fistulization as a complication of targeted therapy for cancer. The committee on human research approved this Health Insurance Portability and Accountability Act–compliant study and waived written informed consent. Based on the records of the senior author and our multidisciplinary Tumor Boards, we retrospectively identified 4 patients (1 man and 3 women with a mean age of 55.25 years; range, 47 to 64 years) who developed tumor fistulization while being treated with targeted therapy consisting of sunitinib (n = 2); bevacizumab (n = 1); and XL184, an investigational c-Met inhibitor (n = 1). All available clinical, imaging, and histopathological records were reviewed, with particular emphasis on treatment administered, CT findings, and clinical course. All 4 patients developed fistulae from large metastatic deposits in the abdomen (mean size before treatment, 10.55 cm; range, 7.4–13.4 cm) to the gastrointestinal tract, and one patient also developed fistulae from a lung metastasis of undetermined size to the bronchial tree. All fistulae manifested as the appearance of air within a pre-existing tumor mass. At the time of fistula detection, disease at other sites in the 4 patients showed signs of regression (n = 1), progression (n = 2), or stability (n = 1). Currently, one patient is alive without evidence of disease, and the 3 other patients are deceased. Targeted therapy can be associated with tumor fistulization to the gastrointestinal tract or tracheobronchial tree; familiarity with the CT findings should facilitate the diagnosis of this complication, which seems to be of variable and patient-specific prognostic significance.
