Background: With advancements in cancer detection and treatment, survivorship rates are increasing worldwide. This shift has extended the role of informal caregivers—family members, friends, and community members—who provide essential support to cancer survivors throughout their journey. However, informal caregivers often face unrecognized burdens, particularly among migrant populations, where cultural and language barriers can complicate caregiving responsibilities. Understanding these caregivers' experiences is critical to developing inclusive healthcare systems that support diverse caregiving needs in oncology.

Aims: This systematic review aimed to explore the experiences of Chinese migrant informal caregivers in providing care for individuals with cancer within international healthcare settings. It sought to understand how cultural values influence caregiving practices and to identify challenges encountered in international healthcare systems.

Methods: A systematic search was conducted on November 28, 2023, across six databases: APA PsycArticles, APA PsycInfo, CINAHL with Full Text, ERIC, MEDLINE, and Exploring Race in Â鶹ÉçÇø. Using keywords like "Chinese migrants," "Informal caregivers," and "Cancer," this review focused on English-language studies offering qualitative insights into Chinese migrant caregiving in oncology. Eight studies met inclusion criteria and were quality-assessed using the CASP checklist. Data were coded and synthesized following Thomas and Harden’s (2008) thematic synthesis approach.

Results: The thematic analysis identified a cyclical relationship among four main themes: Culture, Caregiving, Distress, and Unmet Needs. Cultural values, particularly filial piety, significantly shaped caregiving roles, positioning caregivers as emotional gatekeepers.

This role often heightened caregiver distress, especially in healthcare environments lacking accommodations for traditional cultural practices. In response to these challenges, caregivers frequently turned to culturally familiar solutions, such as Traditional Chinese Medicine (TCM) or family support networks, to cope with psychological strain. These findings underscore the importance of developing culturally aligned support systems to reduce caregiver distress and enhance caregiving outcomes.

Implications: The findings underscore the need for culturally inclusive oncology care that acknowledges the unique challenges faced by Chinese migrant caregivers. Integrating culturally sensitive support mechanisms, such as services that respect the caregiver’s gatekeeping role or incorporate TCM practices, could improve caregiver engagement and resilience. Training healthcare providers to recognize and address cultural influences on caregiving can foster more compassionate and effective care environments. Future research should expand on these insights to include other migrant communities, contributing to a globally informed approach to cancer caregiving.
