ObjectivesAlthough systemic chemotherapy is often administered to patients with malignant bowel obstruction (MBO), its benefit remains unknown. This study assessed the outcomes of patients who received systemic chemotherapy as part of MBO treatment.MethodsFor this retrospective cohort study, data were extracted from records of patients hospitalised due to MBO in a tertiary cancer centre from 2008 to 2020. Eligible patients were not candidates for surgery and received systemic chemotherapy targeting the underlying malignancy causing MBO. Primary objective was to assess patient outcomes after chemotherapy; secondary objectives were rates of intestinal function recovery, hospital discharge and grade ≥3 toxicities. The primary endpoint was overall survival (OS).ResultsA total of 167 patients were included: median age was 55 (18–81) years, 91% had an Eastern Cooperative Oncology Group (ECOG) performance status ≥2, 75.5% had gastrointestinal tumours and 70% were treatment-naive. The media...

CONTEXT AND OBJECTIVE: Nausea and vomiting are major inconveniences for patients undergoing chemotherapy. Despite standard preventive treatment, chemotherapy-induced nausea and vomiting (CINV) still occurs in approximately 50% of these patients. In an attempt to optimize this treatment, we evaluated the possible effects of carbamazepine for prevention of CINV.DESIGN AND LOCATION: Prospective nonrandomized open-label phase II study carried out at a Brazilian public oncology service. METHODS: Patients allocated for their first cycle of highly emetogenic chemotherapy were continuously recruited. In addition to standard antiemetic protocol that was made available, they received carbamazepine orally, with staggered doses, from the third day before until the fifth day after chemotherapy. Considering the sparseness of evidence about the efficacy of anticonvulsants for CINV prevention, we used Simon's two-stage design, in which 43 patients should be included unless overall complete prev...
