Sheraz Yaqub

Sheraz Yaqub is an Associate Professor at the Department of Gastroenterology and Pediatric Surgery, University of Oslo. With a focus on clinical and translational research, his work bridges surgical oncology, cancer epidemiology, and immunology. Key affiliations include collaborations across Scandinavia and Europe in trials and cohort studies.

• Research spans cancer risk factors (BMI, obesity), surgical outcomes, and immune mechanisms in gastrointestinal malignancies.
• Active in randomized clinical trials (SCANDIV, NORPACT-1) and multicenter observational studies (EUR-IPNB).

Scientific Contributions: Over 50 publications in Annals of Surgery, The Lancet, and JEM, with 15 recent articles analyzing:

• Body mass index associations with 10+ cancer types (2025)
• Neoadjuvant therapy in bile duct cancer (2025)
• Minimally invasive pancreatic surgery (2024)
• Immunological mechanisms in the human gut (2017)

Research Themes:

1. Metabolic oncology: Systematic analysis of BMI’s role in cancer incidence and survival across Hodgkin’s lymphoma, penile, and hepatobiliary malignancies.

2. Surgical innovation: Development of peri-firing compression, transfemoral hepatic vein access, and laparoscopic techniques for complex cases.

3. Immune regulation: Identification of intestinal T-cell subsets and macrophage phenotypes that influence anti-tumor responses.
