Predictive Markers of Response and Toxicity in Patients With a Haematological Malignancy Treated With Immunotherapy.

Immunotherapies have substantially improved the prognosis of patients with haematological malignancies. While clinical trial data suggest durable complete response rates, markers associated with non-response to treatment are still poorly described. The identification of predictive markers using demographic, physiologic, biologic, immunologic data as well as patients' treatment history, might enable the optimization of therapeutic sequences and the reduction of treatment toxicity. This study aim to assess markers of toxicity and response following an immunotherapy in patients with a haematological malignancy using real life data. It will allow the development of clinical and therapeutic benchmarks to guide medical decisions in relation to the therapeutic strategies to be implemented for patients benefiting from real-life conditions, in addition to the results obtained in randomized studies.
