Leif Bergkvist

Leif Bergkvist is a Professor at the Centre for Clinical Research, County of Västmanland, affiliated with Uppsala University. He maintains an active research profile in surgical oncology with a specific focus on breast cancer treatment protocols and outcomes.

His primary research interests include:

• Breast cancer surgical treatment and outcomes
• Sentinel lymph node biopsy and axillary lymph node procedures
• Clinical trials (SENOMIC, SENOMAC, CAN studies)
• Impact of anesthesia techniques on cancer survival
• Nutritional aspects of cancer treatment in elderly patients

Dr. Bergkvist's recent publications demonstrate a sustained focus on optimizing surgical approaches for breast cancer patients, particularly regarding when axillary lymph node dissection can be safely omitted. His leadership in the SENOMIC and SENOMAC trials has contributed significantly to evidence-based guidelines for lymph node management in breast cancer. His research spans multiple methodologies from large registry studies to randomized controlled trials, with publications appearing in the highest-impact medical journals including NEJM, The Lancet, JAMA Surgery, and British Journal of Surgery.

His collaborative network extends across Swedish medical institutions with frequent co-authorship with researchers from Uppsala University, Karolinska Institutet, and regional hospitals. This extensive collaboration has resulted in numerous high-impact publications that directly influence clinical practice in breast cancer management.
