Dr. Jurjen Boonstra
As a gastroenterologist, I participate in the LUMC Upper GI cancer team for gastric cancer and oesophagus cancer which diagnoses and treats approximately 180 patients with oesophageal-gastric cancer (OGC) each year. The dismal prognosis of this disease prompts us to search for innovative techniques that potentially could contribute to tailoring the treatment of our patients. Translation cancer research that transforms the latest discoveries in the laboratory into innovative new treatments could contribute to improvement of the outcome OGC patients. Unfortunately, valid preclinical models for this type of cancer are scares. Therefore, one of the key issues in our research is the establishment of valid in vitro (3D tumor cell cultures) and in vivo (patient derived xenografts) models derived from pre-treatment biopsies obtained during endoscopy.
As an interventional endoscopist at the Leiden Center for Interventional Endoscopy (website link), my focus is on endoscopic mucosal and submucosal resection of early neoplasia in the GI tract. Especially, research on the optimal technique for the endoscopic resection of large polyps and early neoplasia colorectal cancer has my interest and is reflected in the participations in several nationwide initiatives. Furthermore, we conduct clinical research that involves the treatment of early colorectal cancer and is mainly focused on which patients can be cured by endoscopic resection and which should referred for additional surgery.
After obtaining his master degree in medicine (2006) at the Rijks University of Groningen, Jurjen Boonstra, obtained his PhD in 2011 on his thesis “Translational research on esophageal adenocarcinoma: from cell line to clinic”, at the ErasmusMC. In 2010, he started his training as gatroenterologist in the Antonius Ziekenhuis Nieuwegein and the UMC Utrecht, with special interest in interventional endoscopy and oncology. In 2016 he started as a staff member at the LUMC, and became head of the endoscopy department in 2017.
