Does cancer survivors' health-related quality of life depend on cancer type? Findings from a large French national sample 2 years after cancer diagnosis

We investigated whether health-related quality of life (HRQL) depends on cancer type, after adjustment for demographic and medical variables. A French national population-based survey was conducted between November and December 2004 to assess surviving cancer patients' HRQL 2 years after diagnosis. HRQL was measured by the 36-Item Short Form Survey scale. The sample included 3900 persons. All cancer diagnoses were entered in the study. We demonstrated that medical and treatment variables have an impact on patients' physical HRQL but not on mental HRQL. Cancer type impacted on physical HRQL, with those suffering from upper aerodigestive tract /lung cancers and haematological malignancies being affected to a greater degree. Disturbing side effects impacted both HRQL domains. Socio-demographic variables had statistically significant effects but not clinically meaningful ones. Socio-economic variables led to potentially clinically meaningful differences for cancer patients' HRQL and represented a socio-economic gradient in HRQL among cancer survivors. From our results, we may assert that cancer survivors, 2 years after cancer diagnosis, share a similar pattern of psychological morbidity, independent of cancer type. Patients disproportionately affected by cancer, such as those with lower educational levels and income, need to be identified and targeted and interventions which address their unique needs and concerns need to be developed.
