KNOWLEDGE ABOUT CANCER MARKER TESTING IN PATIENTS ATTENDING PREMIUM HEALTH CHECK AND EARLY DISEASE SCREENING CENTER OF VINMEC TIMES CITY INTERNATIONAL GENERAL HOSPITAL IN 2026 AND ASSOCIATED FACTORS

Abstract

Objectives: To describe knowledge about cancer marker testing among patients attending the Premium Health Check and Early Disease Screening Center, Vinmec Times City International General Hospital in 2026 and to analyze factors associated with their knowledge scores. Methods: A cross-sectional analytical study was conducted among 442 patients recruited by convenience sampling from April to July 2026. Multivariable linear regression was used to analyze factors associated with knowledge scores. Results: The mean knowledge score was 4.24 ± 2.62/10, and 56.2% of participants answered at least four questions correctly. After adjustment, educational level and occupation were significantly associated with the knowledge score (p < 0.05). Using lower secondary education as the reference, knowledge scores were higher by 0.966, 1.965, and 1.521 points in the vocational/college, university, and postgraduate groups, respectively. Compared with office workers/civil servants, participants who were self-employed/business workers and retirees had scores higher by 0.709 and 1.153 points, respectively. Conclusions: Knowledge about cancer marker testing was limited. Educational level and occupation were associated with knowledge scores. These findings may help inform appropriate communication, counseling, and health education activities.
