A scoping literature review of factors influencing cancer patients' self-perceived burden

Purpose: A cancer diagnosis disrupts the peaceful lives and plans of patients and even their caregivers, and patients can easily feel burdened when they are being cared for by others. However, the influencing factors of selfperceived burden (SPB) have not been summarized, and related research is still in its infancy. This review explores factors related to the SPB of cancer patients and identifies future research directions. Method: A systematic search, including trolling through six electronic databases, was conducted to identity articles published in English and Chinese from January 2003 to April 2022, using key terms related to cancer patients' burden on others; a manual search was also performed on the articles' reference lists. Results: Thirty-three articles were identified. The content was described into three groups: patient-related factors, caregiver-related factors, and family-related (financial) factors. Despite the heterogeneity, patients' physical/ disease factors, psychological factors, social factors, caregiver type, quality of care provided, caregiver physical and psychological status, and financial factors were all correlated with SPB. Conclusions: This literature review shows that SPB imposes a huge burden on cancer patients, and that SPB in cancer patients is influenced by patient-related factors, caregiver-related factors, and family factors. These influencing factors directly or indirectly affect SPB. In addition, SPB is complex and studies related to its factors deserve a further detailed analysis based on the actual situation of the patients in order to make the results more accurate and relevant.
