RESUMEN
CONTEXT: Children with incurable cancer may participate in research studies at the end of life (EOL). These studies create knowledge that can improve the care of future patients. OBJECTIVE: To describe stakeholder perspectives regarding research studies involving children with cancer at the EOL by conduct of a systematic review. DATA SOURCES: We used the following data sources: Ovid Medline, Embase, the Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Web of Science, and ProQuest (inception until August 2020). STUDY SELECTION: We selected 24 articles published in English that examined perceptions or experiences of research participation for children with cancer at the EOL from the perspectives of children, parents, and health professionals (HPs). DATA EXTRACTION: Two authors independently extracted data, assessed study quality, and performed thematic analysis and synthesis. RESULTS: Eight themes were identified: (1) seeking control; (2) faith, hope, and uncertainty; (3) being a good parent; (4) helping others; (5) barriers and facilitators; (6) information and understanding; (7) the role of HPs in consent and beyond; and (8) involvement of the child in decision-making. LIMITATIONS: Study designs were heterogeneous. Only one study discussed palliative care research. CONCLUSIONS: Some families participate in EOL research seeking to gain control and sustain hope, despite uncertainty. Other families choose against research, prioritizing quality of life. Parents may perceive research participation as the role of a "good parent" and hope to help others. HPs have positive views of EOL research but fear that parents lack understanding of the purpose of studies and the likelihood of benefit. We identified barriers to research participation and informed consent.
