Overview

Kei Yamamoto is a researcher affiliated with the University of Tokushima in Japan, specializing in the field of medicine with a focus on surgery, oncology, pulmonary and respiratory medicine, immunology, and oral surgery. Their research encompasses several key topics including cancer immunotherapy and biomarkers, oral and maxillofacial pathology, gastric cancer management and outcomes, immune cell function and interaction, Helicobacter pylori-related gastroenterology studies, gastrointestinal tumor research and treatment, and esophageal cancer research and treatment.

Their recent papers cover a range of topics in oncology and immunology. Notable publications include:

  • "Tumor-infiltrating M2 macrophage in pretreatment biopsy sample predicts response to chemotherapy and survival in esophageal cancer" (2020, Cancer Science)
  • "PD-1+ Tim3+ tumor-infiltrating CD8 T cells sustain the potential for IFN-γ production, but lose cytotoxic activity in ovarian cancer" (2020, International Immunology)
  • "Frequency of Odontogenic Tumors: A Single Center Study of 1089 Cases in Japan and Literature Review" (2021, Head and Neck Pathology)
  • "Clinical importance of the expression of CD4+CD8+ T cells in renal cell carcinoma" (2020, International Immunology)
  • "The impact of ICOS+ regulatory T cells and Helicobacter pylori infection on the prognosis of patients with gastric and colorectal cancer: potential prognostic benefit of pre-operative eradication therapy" (2020, Cancer Immunology Immunotherapy)

Yamamoto frequently publishes in journals such as International Immunology, Head and Neck Pathology, Cancer Immunology Immunotherapy, Esophagus, and Gastrointestinal Endoscopy, indicating a consistent presence in specialized venues relevant to their research fields.

Their collaborative network includes regular coauthors such as Yuichiro Doki, Hisashi Wada, Yukinori Kurokawa, Katsutoshi Kokubun, and Kei Nakajima, with multiple joint publications reflecting ongoing professional relationships in their research community.

The range of subfields their work covers demonstrates an interdisciplinary approach, integrating surgical techniques with oncological and immunological studies focused on cancer and gastrointestinal diseases.
