Frailty score of older patients with haematological malignancies: unsuspected role of mild cognitive impairment.

Frailty assessment in older patients with haematological malignancies is extremely beneficial in order to optimize treatment decisions and supportive interventions. A comprehensive geriatric assessment can provide a better understanding of the functional age than clinical judgement by evaluating several skills domains such as physical function, autonomy, comorbidities, nutrition, cognition, psychological status and social support. However, the use of a multidisciplinary geriatric assessment may fail to detect unsuspected vulnerability such as mild cognitive impairment among so-called "clinically fit" patients.
