Torgrim Tandstad

About

Torgrim Tandstad, MD, PhD is Associate Professor at NTNU and Senior Consultant in Oncology at St. Olavs Hospital. He specializes in urogenital cancers, particularly testicular and prostate cancer, and serves as leader of the binational collaboration SWENOTECA. His research includes clinical trials, imaging, and long-term survivorship, with more than 70 publications in international peer-reviewed journals. Tandstad supervises master’s and PhD students, participates in international expert panels, and works to improve survival and quality of life for cancer patients.

He graduated in Medicine from NTNU in Trondheim in 2003 and earned his PhD in Clinical Medicine in 2011. His doctoral thesis, Vox Populi, was based on population-based studies of testicular cancer and contributed to new insights on treatment, survival, and late effects. Throughout his career, he has maintained a strong focus on patient-centered issues, clinical trials, and treatment quality.

A central engagement is his leadership role in SWENOTECA (Swedish–Norwegian Testicular Cancer Group), where he has served as chair since 2013. He has held key responsibilities in developing guidelines, clinical protocols, and prospective patient data collection. SWENOTECA has served as a model for binational collaboration, with results that have had significant impact on treatment practices worldwide. Tandstad also leads the Norwegian Testicular Cancer Group and has played a central role in developing national guidelines and care pathways for testicular cancer.

He is also active in prostate cancer research, participating in large-scale clinical projects such as the SPCG19/Grand-P trial, ProstateCAG, and the 180N project, where he co-leads the work package on nuclear medicine imaging in prostate cancer. In addition, he has contributed to digital innovation projects such as CaReScreen, which develops decision-support tools for cancer rehabilitation. Through these initiatives, Tandstad has helped bridge clinical practice, technology, and patient-centered solutions.

Internationally, he is a member of the EAU Guidelines panel for testicular cancer, the Global Germ Cell Cancer Cooperative Group (G3), and the European Germ Cell Cancer Consensus Group. He has been an invited speaker at leading international conferences such as ASCO, EAU, and ESMO. His scientific output includes more than 70 peer-reviewed publications between 2009 and 2025, of which 31 were published since 2020.

As of October 2025, his Google Scholar profile shows an h-index of 27, an i10-index of 44, and approximately 4,191 citations. This reflects a research activity with substantial impact both nationally and internationally.

Through his combination of clinical expertise, research leadership, teaching, and international collaboration, Torgrim Tandstad has established himself as a key figure in urogenital oncology. He is particularly committed to developing knowledge that improves survival and quality of life for cancer patients, and to building research-based structures for better treatment and follow-up.
