Cancer prevalence in Indonesia is 1.8 per 1000 population in 2018. Early diagnosis is needed to reduce the mortality rate and one of which is by examining vanillylmandelic acid (VMA) level as tumor markers. VMA is a catecholamine metabolite whose level will increase in several neuroendocrine tumors. This study was conducted to determine the proportion of positive VMA in urine of patients with suspected neuroendocrine tumors in Jakarta and its association with age and gender. This study was a cross-sectional design using secondary data of urinary VMA laboratory examination from 295 patients who suspected neuroendocrine tumors period 2010 to 2019 in Laboratory of Department of Biochemistry and Molecular Biology, Faculty of Medicine Universitas Indonesia. Qualitative examination of urinary VMA used spot test. Positive examination result showed levels of VMA in urine >8mg/24 hours, while negative result showed 8mg/24 hours. Inclusion criteria were subject data with a provisional diagnosis of neuroblastoma, pheochromocytoma, and paraganglioma. The proportion of positive VMA in urine of suspected neuroendocrine tumor patients was 14,2%. There was a significant association between VMA in urine with age (p 0,023), while gender was not significant (p 0,885). In conclusion, there was an association between urinary VMA of suspected neuroendocrine tumor patients with age, however no association with gender.
