Qualitative meta‐synthesis is a coherent approach to answering an overarching research question by synthesising past qualitative studies so as to create new meanings from their results. We conducted a qualitative meta‐synthesis to systematically evaluate and integrate the caregiving experiences of adult children providing care for an elderly parent with cancer. The search was conducted in the databases Web of Science, PubMed, Embase, MEDLINE, Cochrane Library, Grew Literature in the Health Sciences, CNKI, WanFang Data, VIP, SINOMED and China Academic Journals as well as Chinese grey literature databases (China Academic Conference Literature Database/中国学术会议文献数据库, National Science and Technology Library) from inception to June 9, 2021. Thirteen studies were included in the final synthesis. The caregiver experiences they describe are synthesised into three primary themes: care needs, care burden and care gains, with numerous secondary themes. Besides our findings that seem to align with those from studies focused on other cultures, we have highlighted three main discoveries from the synthesis that stand out in the Chinese context: (1) many sub‐themes related to specific caregiving skills; (2) a strong expectation for health professionals to improve their communication skills with family caregivers; (3) the negative and positive influences of filial piety in caregiving experiences. Our findings can help multidisciplinary healthcare teams in China support adult children as caregivers in their emphasis on improving caregiver education and training, ways of making the most of potential care gains, and ways of easing care burdens.
