INTRODUCTION: Immunotherapy revolutionized cancer care in the last decade and, notably among its tools, the programmed cell death protein-1 (PD-1) inhibitors.

OBJECTIVE: To evaluate the toxicity profile, determining its frequency, causality, and severity associated with treatment with PD-1 inhibitors in patients treated at an oncology service in the private health sector in Belo Horizonte.

METHODS: Observational, retrospective, and cross-sectional study, based on the review of electronic medical records. The eligibility criteria included patients over 18 years old with a diagnosis of any cancer and staging, receiving a PD-1 inhibitor from January 2017 to January 2020.
