Sayumi Tahara's research focuses on gastric cancer and the role of DNA methylation (a chemical modification of DNA that can turn genes on or off) in its development, particularly in relation to Helicobacter pylori infection, a bacterium linked to stomach cancer. Work also extends into endoscopic imaging techniques for detecting colorectal and gastric abnormalities, and broader gut-related conditions such as ulcerative colitis and postoperative complications. This research combines molecular biology and clinical gastroenterology to better understand cancer risk, prognosis, and detection.
Publication output was highest around 2017-2019, dropped sharply in 2020-2022, and has since shown a modest resurgence with fluctuating annual counts through 2024-2026.
