Diseases of esophagus and stomach
The group consists of surgeons, oncologists, a gastroenterologist and pathologist and works for optimization of treatment.
About the group
Purpose of the group is optimalisation of
- Oncologic and surgical treatment of patients with esophageal cancer and gastric cancer with focus on morbidity, complications and quality of life.
- Treatment of patients with benign esophageal diseases (perforations, achalasia, diverticula)
- Treatment of hiatal hernias and incisional hernias
These goals can be facilitated by participating in studies. A focus will also be translational research aiming at identifying sensitive biomarkers for early detection of cancer.
Projects and Research
- Continual monitoring of complications and survival (quality assurance) following resection for esophageal- and gastric cancer
- Continuous biobanking of blood samples and tumor tissue ((esophageal cancer (n= 450), gastric cancer (n=290)) to a biobank since 2013 for research purposes. Analyses of biobank material have been ongoing since 2019.
- Studies on esophageal cancer on biomarkers /local treatment of dysplasia and early cancer/total minimally invasive resection for more advanced cancer are ongoing (PhD study)
- A pilot project on to studying microcirculatory changes in the gastric tube before, under and after surgery for esophageal cancer has been completed. Results are planned for publication.
- The INNOVATION study. European randomised multicenter study, in which patients with HER-2 positive gastric cancer were randomized in three arms for i) chemotherapy (perioperative FLOTx4x2 eller CiFU/CiXel), ii) chemotherapy with trastuzumab or iii) chemotherapy with trastuzumab+pertuzumab. End point is overall survival. EORTC study. Inclusion is still ongoing.
- INTENSE study. Effect of perioperative use of chemotherapy (FOLFIXFLIRIx4x2) in patients with resectable gastric and gastroesophageal junction adenocarcinoma. Ongoing inclusion.
- NEEDS study. Neoadjuvant chemoradiotherapy for esophageal squamous cell carcinoma versus definitive chemoradiotherapy with salvage surgery as needed. Multicenter study started in 2021.
- VESTIGE study. Postoperative Immunotherapy (nivolumab plus ipilimumab) vs Standard Chemotherapy for Gastric Cancer stage Ib-IVb, including esophagogastric junction adenocarcinoma, with high risk for recurrence (defined by ypN1-3 and/or R1 status) (VESTIGE). Venter på REK/SLV godkjenning.
- The upper GI International Robotic Association (UGIRA) for contribution of patients to the International Registry for Robot-Assisted Minimally Gastrectomy (RAMIG) for gastric cancer. Dr. C. de Jongh, University Medical Center, Utrecht, is project leader. Professor Tom Mala is responsible for recruitment of patients to this registry at OUS from 2021.
- The kiNETiC – a Register based Randomised Controlled Trial- Ng-tube post–EsophagecTomy Complications. A Scandinavian multicenter study. Three out of four University clinics in Norway will participate. Awaiting decision from the ethical committee. Associate prof. Jacob Hedberg, Department of Surgical Sciences, Uppsala is responsible. Prof. Tom Mala is responsible at OUS.
- Keynote 061 (randomised study with palliative chemotherapi in 2. line for gastric cancer; standard chemotherapy vs. MK3475. MSD study. Inclusion from August 2015.
- Keynote 180 (phase II study, palliative chemotherapy in 3. line for esophageal cancer; MK3474). MSD study. Inclusion from January 2016.
- Keynote 181 (randomised phase III study, palliative chemoterapy in 2. line for esophageal cancer; standard chemotherapy vs MK3475). MSD study. Inclusion from January 2016.
- Nordic NEC registry (registry study for all patients with neuroendocrine carcinoma of the GI-tract (GEP-NEC)). Inclusion from 2013. NNTG (Nordic Neuroendocrine Tumor Group). See reference 3 in the publication list (GO Hjortland is co-author).
- ET-NEC. Nordic one armed phase II study for patients with GEP-NEC, Ki67 index 20-55%, first line treatment with everolimus and temozolomid. Inclusion from October 2014. NNTG study.
