Impact of the relationship of primary caregiver support in the quality of life of patients with advanced cancer

Introduction: This study evaluated the impact of the primary caregiver on the quality of life (QL) of patients with advanced cancer. Method: The research design is exploratory descriptive-correlational with non-probabilistic sampling for convenience with error not exceeding 5%. The sample was composed of 34 patients diagnosed with advanced cancer and their respective primary caregivers, all of whom from a hospital unit specialized in palliative treatment. The instruments FACT-G, SF-36 and Zarit's caregiver overload scale were used. Results: The results show that the overall QL of cancer patients is perceived negatively, which suggests that physical and emotional health problems deteriorate the patient's daily physical and social activities. With regard to caregivers, these rate their own QL positively; however those who provide care to patients with a more advanced state of cancer present a slight amount of overload in the physical, social, psychological and economic aspects of their lives. As such, the study concluded that the patient's functional state dimension is positively affected by the caregivers's social functions, welfare and vitality. Conclusions: it can be observed that indeed, the level of deterioration in the functional and physical dimensions of the patient has an infuence on the perception that they have of their QL, in addition to caregivers of patients in the more critical stages of the illness regarding themselves as overloaded, probably due to the more active role that they have to take on.
