Most elderly patients, with cancer are cared for, by a family member who may be affected by various stressors that can influence their health and quality of life (QOL).

To explore depression, quality of life and its related factors among caregivers of elderly patients with cancer.

This is a descriptive and analytical cross-sectional study including 40 primary caregivers of old patients aged 65 or older, with cancer in oncologic radiotherapy service in university hospital Habib Bourguibain Sfax, Tunisia. The short form health survey (SF-36) and Beck inventory (13 items) were used to assess respectively QOL and depression.

The average age of caregivers was 44.62 years. The sex ratio (M/F) was 0.9. Most of caregivers (75%) had impaired QOL (score ˂ 66.7). The two main components of SF-36 were altered with a standard score of 45 for the physical component and 41.1 for mental component. According to Beck inventory, Depression was present in 67.6% of cases. Impaired QOL of life was significantly correlated with somatic illnesses in the caregiver (P = 0.016), advanced stage of cancer (P = 0.01), financial difficulties (P = 0.04), the non-cohabitation with the patient before the disease (P = 0.031) and depression (P = 0.00).

According to our study, caregiving can have a negative effect on the caregiver's mental and physical health. Assistance and information from healthcare professionals are the key to improving the ability of caregivers to cope with caring for older patients with cancer.
