RESUMO
Docetaxel is a taxane, which is a class of chemotherapy agent used in the treatment of multiple malignancies. It is known to have gastrointestinal side effects which can range from mild symptoms such as nausea and diarrhea to more severe complications such as neutropenic enterocolitis. In the current literature, taxanes have not been described to cause upper gastrointestinal bleeding and melena. Here, we present a case of a 54-year-old woman with breast cancer who developed dizziness, fatigue, and melena after receiving chemotherapy. Esophagogastroduodenoscopy revealed diffuse gastric erosions as well as ulceration and linear superficial lesions in the duodenum; biopsies from these sites showed taxane-induced toxicity. Her bleeding resolved with medical therapy and subsequent removal of docetaxel from her chemotherapy regimen. This case identifies upper gastrointestinal bleeding as a previously undescribed side effect of docetaxel therapy. Recent docetaxel use should be included in the differential diagnosis for upper gastrointestinal bleed, and diagnosis should lead to consideration of cessation of docetaxel or substitution with another chemotherapeutic agent.
