Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Cancer
  • Gene

His scientific interests lie mostly in Internal medicine, Gastroenterology, Pathology, Endocrinology and Hepatitis C virus. His study in Vasodilation, Endothelium, Hepatocellular carcinoma, Hepatology and Cancer are all subfields of Internal medicine. His studies examine the connections between Gastroenterology and genetics, as well as such issues in Surgery, with regards to Radiology.

His work carried out in the field of Pathology brings together such families of science as Vascular endothelial growth factor, Angiogenesis, Metastasis and Endoscopy. His Endocrinology research focuses on subjects like Receptor, which are linked to Hepatic stellate cell. Kazuaki Chayama combines subjects such as Hepatitis C and Genotype with his study of Hepatitis C virus.

His most cited work include:

  • A proposed system for the nomenclature of hepatitis C viral genotypes (960 citations)
  • A multivariate analysis of risk factors for hepatocellular carcinogenesis: A prospective observation of 795 patients with viral and alcoholic cirrhosis (635 citations)
  • Whole-genome sequencing of liver cancers identifies etiological influences on mutation patterns and recurrent mutations in chromatin regulators (608 citations)

What are the main themes of his work throughout his whole career to date?

His primary scientific interests are in Internal medicine, Gastroenterology, Virology, Hepatitis C virus and Hepatocellular carcinoma. Kazuaki Chayama has researched Internal medicine in several fields, including Endocrinology, Immunology and Cardiology. The study incorporates disciplines such as Cancer, Ribavirin and Surgery in addition to Gastroenterology.

His Cancer study combines topics from a wide range of disciplines, such as Cancer research and Pathology. His Hepatitis C virus study combines topics in areas such as Interferon and Hepatitis C. His Hepatocellular carcinoma study integrates concerns from other disciplines, such as Carcinoma, Radiology, Retrospective cohort study and Oncology.

He most often published in these fields:

  • Internal medicine (51.24%)
  • Gastroenterology (30.38%)
  • Virology (16.12%)

What were the highlights of his more recent work (between 2017-2021)?

  • Internal medicine (51.24%)
  • Gastroenterology (30.38%)
  • Hepatocellular carcinoma (12.85%)

In recent papers he was focusing on the following fields of study:

Kazuaki Chayama spends much of his time researching Internal medicine, Gastroenterology, Hepatocellular carcinoma, Hepatology and Virology. His Internal medicine research is multidisciplinary, incorporating perspectives in Oncology and Hepatitis C virus. His studies in Hepatitis C virus integrate themes in fields like Hepatitis C and Combination therapy.

His Gastroenterology study also includes fields such as

  • Regimen most often made with reference to Adverse effect,
  • Fatty liver which connect with Fibrosis. His Hepatocellular carcinoma research incorporates elements of Liver disease and Hazard ratio. His study in Hepatitis B virus, Virus and Interferon is done as part of Virology.

Between 2017 and 2021, his most popular works were:

  • Pan-cancer analysis of whole genomes (538 citations)
  • Genomic characterization of biliary tract cancers identifies driver genes and predisposing mutations. (81 citations)
  • Efficacy and safety of glecaprevir/pibrentasvir in Japanese patients with chronic genotype 1 hepatitis C virus infection with and without cirrhosis. (71 citations)

In his most recent research, the most cited papers focused on:

  • Internal medicine
  • Cancer
  • Gene

His primary areas of study are Internal medicine, Gastroenterology, Hepatocellular carcinoma, Cirrhosis and Hepatitis C virus. In his study, he carries out multidisciplinary Internal medicine and In patient research. His Gastroenterology research incorporates themes from Odds ratio, Multivariate analysis, Hazard ratio, Confidence interval and Ribavirin.

His study looks at the relationship between Ribavirin and fields such as Hepatitis C, as well as how they intersect with chemical problems. His research on Hepatocellular carcinoma also deals with topics like

  • Liver disease that intertwine with fields like Immunology,
  • Oncology which is related to area like Liver function and Biopsy. His Cirrhosis research is multidisciplinary, relying on both Body mass index and Nonalcoholic fatty liver disease.
