Quality of life as an endpoint
Quality of life (QoL) assessment adds useful information to the efficacy and safety data obtained in clinical studies. It contributes to the evaluation of different treatments and identifies patients who might benefit from supportive interventions. QoL data can be used to inform policy and resource allocation, reveal benefits to patients despite objective toxicity, and be of prognostic value. Evaluation of patient’s QoL might help to determine the suitable moment to start specific palliative interventions.
