## TL;DR

This study explores homocysteine, vitamin B12, and folic acid as potential biomarkers for early detection and monitoring of gastric cancer.

## Contribution

The study identifies a novel triad of biochemical markers for gastric cancer screening and early diagnosis.

## Key findings

- Significant statistical differences in homocysteine, vitamin B12, and folic acid levels were found between gastric cancer patients and controls.
- The triad of biomarkers showed diagnostic value for gastric cancer.
- The findings suggest potential for integrating these markers into routine diagnostic protocols.

## Abstract

Gastric cancer has been demonstrating a reduction in the number of cases over the past decades, largely attributed to advancements in public health practices and increased accessibility to educational initiatives for the general population. Nevertheless, it persists as the third leading cause of mortality globally among both men and women. These fatalities are typically associated with delayed disease detection. The current study assessed the levels of homocysteine, vitamin B12, and folic acid as a means of establishing a screening biomarker profile that could be integrated into routine testing protocols to facilitate swift diagnosis of the illness. A total of 207 control subjects and 207 individuals with gastric cancer were scrutinized, with biochemical measurements conducted using chemiluminescence for homocysteine, folic acid, and vitamin B12. The two groups were matched based on age, tumor location, subtype, tumor classification, presence of Epstein-Barr Virus infection (EBV), and Helicobacter pylori (H. pylori). Significant statistical variances were identified in the mean levels of the triad of substances among cancer patients when compared to the control group for all corresponding variables. In conclusion, our study indicated that analyzing the triad of homocysteine, vitamin B12, and folic acid holds diagnostic value for gastric cancer and could potentially serve as an effective screening marker for this type of cancer in the future.
