Immunotherapy

Immunotherapy with ’checkpoint-inhibitors‘ has significantly improved outcomes for patients with a range of malignancies. However, significant immune-mediated toxicities of these therapies are well-described. These immune-mediated toxicities can affect virtually all organ systems and are potentially fatal. The timing of onset of the adverse effects is dependent on the organ system affected and can occur after completion of the treatment. The increasing utilisation of ‘checkpoint-inhibitors’ means that Acute Physicians are likely to see a number of immune-mediated complications presenting to the AMU.

The fundamental principles of management of immune-mediated toxicities are early recognition, supportive treatment, escalating steroid therapy (dependent on the severity of the toxicity), close liaison with Oncology and specialist organ team input. Research into the optimal strategies and pathways for the management of immune-mediated toxicity, as well as increased collaboration between Acute Physicians and Oncologists, will be necessary.
