Advanced cancer poses significant challenges that extend beyond the patient to include family caregivers, who play a vital role in treatment adherence, symptom management, emotional support, and palliative care. This article presents a narrative review of existing literature along with findings from an experimental study conducted among caregivers of patients with advanced cancer. The study aimed to evaluate the effectiveness of structured caregiver involvement on patient outcomes and caregiver burden. A total of 50 caregivers were included and divided into experimental and control groups. Results demonstrated significant improvement in patient symptom control, treatment adherence, quality of life, and a reduction in caregiver burden in the experimental group. The findings highlight the importance of integrating caregiver-centered interventions into advanced cancer care.
