Overview

Chemotherapy-induced cognitive disorders, such as memory problems, slowness of execution, inability to concentrate, and language difficulties, are sequelae that occur in patients undergoing chemotherapy or who have received chemotherapy. These symptoms lead to a degradation of the patients' quality of life and can have a significant social and familial impact. They are most commonly described in solid oncology, particularly in patients with breast cancer. Data about patients with hematological malignancies are scarce, but they seem to show the same phenomenon as in solid oncology. Indeed, many chemotherapies are used both in hematology and solid oncology and may therefore cause similar effects on cognition. Additionally, due to their mechanism of action, some chemotherapies specifically used in hematology could induce cognitive disorders. Hematology-treated patients are probably also affected by these disorders and may consequently experience a reduced quality of life.

The objective of this study is to assess the changes in cognitive functions in patients receiving chemotherapy for the treatment of hematological malignancies, using neuropsychological tests and a self-administered questionnaire, compared to a control group, as well as their potential impact on quality of life, fatigue, anxiety, and depression.
