The main objective is to estimate the prevalence of severe fatigue, as part of the cancer-related fatigue (CRF) definition, in childhood cancer survivors (CCS).
The second objective is to describe the course of severe fatigue following cancer treatment and examine risk factors for, or factors associated with, severe fatigue (e.g. demographic, life-style, cancer and cancer treatment-related factors and co-morbidity). We will not include studies that assess the genetic basis of severe fatigue.
This is a protocol.
