New publication in a high-ranked journal: Surgeon proficiency gain and survival after gastrectomy for gastric adenocarcinoma
The European Journal of Cancer (impact factor 10) has accepted the study with the title “Surgeon proficiency gain and survival after gastrectomy for gastric adenocarcinoma: A population-based cohort study”.
The study identified surgeon proficiency gain curves for gastrectomy regarding long-term survival in gastric adenocarcinoma, which seem to be at least partly mediated by improvements regarding tumour-free resection margins and lymph node yield. The findings suggest that surgeons should conduct at least 20 gastrectomies with experienced support before performing these operations independently. The authors are Johannes Asplund, Hugh Mackenzie, Sheraz Markar and Jesper Lagergren.

Eivind Gottlieb-Vedi is awarded the Dimitris N. Chorafas prize 2022
Eivind Gottlieb, senior researcher at the Upper Gastrointestinal Surgery research group, at the Department of Molecular Medicine and Surgery is awarded the prestigious Dimitris N. Chorafas prize for his doctoral thesis Improved surgical treatment of oesophageal cancer.
The prize amounts to 5.000 USD and is meant to reward pre-graduate scientific contributions within the doctoral education.
"Dr. Eivind Gottlieb-Vedi is awarded the 2022 Dimitris N. Chorafas prize for his efforts to improve the clinical management of patients undergoing surgery for oesophageal cancer. In his doctoral thesis, Eivind determined that among several possible surgical approaches, so-called keyhole surgery consistently improved long-term survival; established that extensive removal of lymph nodes does not influence clinical outcome and should be avoided; and developed practical guidelines about how to best train oesophageal cancer surgeons for improving the clinical outcomes. The results are rigorous and statistically sound, published in top journals in the field, and are readily implementable in clinical practice."

Funding from the Swedish Cancer Society
Jesper Lagergren received project funding 6.75 million SEK (2.25 million/year) for the next 3 years (2022-2024) from the Swedish Cancer Society. Sheraz Markar received 2.4 million SEK (0.8 million/year) for the same period. These funding covers several research projects ongoing in our group.
Funding from the Nordic Cancer Union
Jesper Lagergren received 80,000 EUR from the Nordic Cancer Union for year 2022. The grant increased from year 2021 and will fund the Nordic Helicobacter Pylori Eradication Project (NordHePEP), which focuses on the link between Helicobacter pylori eradication treatment and cancer risk (especially and oesophageal adenocarcinoma) in the Nordic countries.
Monday 15th November the research groups Upper Gastrointestinal Surgery (UGIS) and Surgical Care Science (SCS) met at Hotel Skeppsholmen for a Planning Day. The outcomes from the last year’s planning day were presented by the research group leaders Jesper Lagergren (UGIS) and Pernilla Lagergren (SCS). Future plans and goals for the years ahead were discussed for each work category – administration and senior researchers, PhD students and statisticians, as well as all together.
The groups also took part to a session lead by Anders Wiberg, from KI Health Promotion, which focused on how to integrate physical activities in the office's daily life.
It was nice to finally meet in person and to discuss our future work and set the aims to develop our research!
The prestigious journal Gastroenterology (impact factor 22.7)
has accepted our original study titled “Incidence and mortality in upper gastrointestinal cancer after negative endoscopy for gastroesophageal reflux disease”, which is based on data from the Nordic Antireflux Surgery Cohort (NordASCo). Among the authors are Dag Holmberg (first author), Giola Santoni, Joonas Kauppila, John Maret-Ouda and Eivind Ness-Jensen and Jesper Lagergren (last author).
This cohort study included >1 million patients with gastro-oesophageal reflux disease. Patients with a normal upper endoscopy had strongly decreased risks of developing upper gastrointestinal cancer for 5 years as well as of dying from upper gastrointestinal mortality for 10 years, compared to patients who did not undergo endoscopy. This information may guide future screening and surveillance strategies.
Warm congratulations to Eivind Gottlieb-Vedi for his excellent thesis defence
which took place Friday the 10th of September at Bioclinicum (Karolinska Hospital). Professor Jane Blazeby from Bristol University was the opponent and joined the defence on Zoom.
Joonas Kauppila appointed professor at Oulu University

The position, which includes 30% research, starts in September 2021. Joonas will be one of the youngest ever professors within the medical faculty in Finland. He did his postdoc in our research group with Jesper Lagergren as supervisor.
Many warmest congratulations to this enormous success Joonas!
Congratulations to Jiaojiao Zheng
for an excellent thesis defence on Friday the 11th June. The defence took place on site and on Zoom.
New study in Annals of Surgery
The study titled “Extent of lymphadenectomy and long-term survival in esophageal cancer” has been accepted for publication in the prestigious surgery journal Annals of Surgery (Impact Factor 10.1). First author is Eivind Gottlieb and last author is Jesper Lagergren. Other authors are Joonas H. Kauppila, Fredrik Mattsson, Jakob Hedberg, Jan Johansson, David Edholm, Pernilla Lagergren, and Magnus Nilsson. The paper, which will be included in Eivind Gottlieb´s thesis, was a population-based cohort study from Sweden and Finland. The results indicate that extensive lymphadenectomy during surgery does not improve survival in esophageal cancer. However, the results suggest that removal of a moderate amount (20-30) lymph nodes may be an optimum range in patients with advanced tumor stages (T3/T4) and in those not receiving neoadjuvant therapy.
Congratulations to Manar Yanes
for his excellent thesis defence on 26th March 2021, which took place both on site (KI Campus) and on Zoom.
