Person- or patient centredness (PC) is increasingly recognized as a core component of high-quality healthcare and a critical pathway to achieving equitable, person-responsive cancer services. While the concept of PC has been widely adopted and measured in high-income countries, its implementation and evaluation in low- and middle-income countries (LMICs) remain limited and inconsistent. This scoping review maps existing research on measures of PC in LMICs, with a specific focus on cancer care. We identified 345 studies published between 2004 and 2022 that reported on PC in LMICs, of which 20 focused on cancer. Most studies were conducted in upper-middle-income countries and used cross-sectional designs. Patient satisfaction was the most commonly measured domain, followed by communication and shared decision-making. However, foundational aspects of PC – such as patient rights, coordination of care and culturally responsive services – were rarely evaluated. Only 41% of studies used validated tools, and most interventions occurred at the facility level, with few system-level evaluations. Using the Santana et al. framework, which categorizes PC domains into structure, process and outcomes, we found that structural and systemic components of PC were particularly underrepresented in LMIC research. This suggests a gap between policy ambitions and practical implementation, especially in cancer care settings where multidisciplinary coordination and patient engagement are essential. This review advances the field by systematically documenting how PC is currently measured in LMICs and identifying significant limitations in scope, equity and contextual relevance. Findings highlight the urgent need for validated, culturally adaptable tools and frameworks that reflect the realities of LMIC health systems. Addressing these gaps is essential for scaling person-centred cancer care and strengthening health systems toward universal health coverage.
