RESUMO
Previous studies have demonstrated a marked reduction of haematological and non-haematological toxicity if weekly doses of docetaxel <40 mg/m2 were used. Reviewing the literature, neutropenic enterocolitis is uncommon but not unknown in patients treated with taxane-based chemotherapy. Although this complication occurs rarely, here we report on two patients, one with metastatic breast cancer and one with non-small-cell lung cancer, treated on a weekly schedule with single-agent docetaxel. Both patients developed excessive and fatal haemorrhragic gastroduodenitis and enterocolitis associated with grade 2 and 3 neutropenia. We would like to stress the importance of symptoms such as abdominal pain and tenderness, fever, diarrhoea and mucositis, with or without neutropenic fever, in patients treated with docetaxel-based chemotherapy. These symptoms should alert the physician and supportive care management should be started aggressively and immediately.
