About me

  • Professor of Surgery at the Department of Clinical Science, Intervention and Technology

    Magnus Nilsson was born in Lund in 1968 and studied medicine at KI, graduating in 1992. He became a specialist in surgery in 2000 and has above all worked at Karolinska University Hospital where he is a Senior Physician at the Department of Upper Abdominal Diseases today. He served as the Head of the Section of Upper Abdominal Diseases at the Gastrocentrum in 2007–2014.

    Magnus Nilsson earned his PhD at KI in 2004 and became a Docent in 2011. Since 2014, he is been Head of the Division of Surgery and since 2022 the Division of Surgery and Oncology, at the Department of Clinical Science, Intervention and Technology (CLINTEC) at Karolinska Institutet. Since 2017 he also serves as Vice-Chairman of CLINTEC. He was the Chairman of the Swedish Association for Upper Abdominal Surgery (SFÖAK) 2015-2017 and is currently the Editor-in Chief of the international peer-reviewed journal Diseases of the Esophagus. Magnus Nilsson was appointed Professor of Surgery at Karolinska Institutet on 1 July 2017.

Research

  • Mainly clinical and translational research within the fields of gastric and oesophageal cancer. He has led, and still leads, several trials addressing perioperative chemo- and chemoradiotherapy for oesophageal and gastro-esophageal junctional cancers. In the last years clinical and translational research efforts have also been directed towards new treatments for peritoneal metastases in gastric cancer.

Teaching

  • Magnus Nilsson has extensive experience of teaching on all university levels. He is since 2017 responsible for the teaching within the subject area of surgery for undergraduate medical students at Karolinska Institutet.

    There are two types of esophageal cancer, adenocarcinoma and squamous cell carcinoma. Curative treatment for adenocarcinoma is based on surgery to remove the esophagus after chemotherapy or combined treatment with chemotherapy and radiation, so-called chemoradiotherapy (CRT). In the case of squamous cell carcinoma, the most established treatment is surgery after pre-treatment with CRT, but in this type of esophageal cancer there is also an option to treat with CRT for curative purposes, then given in a higher dose and with careful follow-up afterwards, with the possibility of surgery in cases where the tumor does not disappear completely or return locally. In the randomized study NeoRes 2, we investigate for adenocarcinoma of the esophagus whether an extended wait of 10-12 weeks between completed CRT and surgery, compared to the usual wait of 4-6 weeks, results in better tumor response, less risk of residual tumor tissue and better recovery before surgery . In the randomized study NEEDS, we investigate for squamous cell carcinoma of the esophagus whether CRT followed by careful controls, and surgery only when needed, provides similar survival but with a better quality of life, compared to today's standard treatment with CRT followed by mandatory surgery. For esophageal adenocardinomas, a randomized trial demonstrating oncologic benefits and better quality of life after delayed surgery would be of great value as many patients are not recovered and ready for major surgery within the conventional time frame of 4-6 weeks. In the case of squamous cell carcinoma, the vast majority of patients today routinely undergo surgery after CRT. However, the operation causes a lifelong reduction in the quality of life. If CRT with surgery only when really needed for local tumor control were to be shown to provide as good a survival rate as routine surgery, then it is likely to become the new standard treatment worldwide.

  • Two studies carried out in a Nordic research network on cancers of the esophagus or upper stomach where the type of treatment given for curative purposes is determined by lottery.

    Cancer of the esophagus has poor prognosis. The best chance of being cured has patients who are first treated with chemotherapy, or a combination of chemotherapy and radiotherapy, and then operated. However, it is not entirely clear which pretreatment is better, chemotherapy alone or combination of chemotherapy and radiation. It is also not clear how long you should wait with surgery after pretreatment with chemotherapy and radiation. Previous preliminary data suggest that you can get better treatment effect if you wait much longer with the surgery than is normal today. This research project consists of two studies in which we each draw two different treatment options. In study 1, we draw between giving pretreatment with chemotherapy alone and giving pretreatment with combination of chemotherapy and radiation. In study 2, all patients receive combination therapy with chemotherapy and radiation, but instead we draw between waiting 4-6 weeks with the operation, which is common today, and waiting 10-12 weeks, which in preliminary, unlisted studies, shown promising results with better shrinkage effect on the tumor. I hope with this research can contribute with well-founded knowledge about how to pre-treat with chemotherapy and radiation before surgery of esophageal cancer in as efficient and safe manner as possible. In the first study, we hope to answer the question whether radiation has a place in the pretreatment or not, which most previous data suggests, but this study could ultimately determine. In the second study, we hope to get an answer to the question of how long one should wait for surgery of esophageal cancer after pretreatment with chemotherapy and radiation.
