BioXmark™

Study Description

Brief Summary: This study aims to evaluate if BioXmark™, a surgical marker, may efficiently and safely be used to preoperatively mark the proximal and distal resection line 5 cm proximal and distal to the tumor margin of gastroesophageal-junction adenocarcinoma (GEJ AC). Furthermore, to determine if placing the resection margin according to the resection margin defined by BioXmark™ is superior to the current standard of a proximal resection line estimation by the individual surgeon based on the intraoperative findings.

Detailed Description: In Denmark, the national guidelines for GEJ AC surgery are an R0 resection with a minimum 5 cm proximal and distal resection margin, measured in vivo. During the operation, the primary surgeon sets the resection margin according to the guidelines, with 5 cm on either side. The Danish national guidelines are clear, but the literature behind them is not, and the recommendations for resection margins vary worldwide. With the lack of a strong literature-backed guideline and a surgical approach that is heavily dependent on the individual surgeon's estimate, the risk of a microscopic positive resection margin (R1 resection) increases. Both problems, namely resectability at the definitive surgery and the incidence of microscopic positive resection margins after resection, may be improved by preoperatively marking the tumor margins in vivo. This could be achieved with an endoscopically placed surgical marker. One such surgical marker is BioXmark™, a liquid injectable and adherent fiducial marker that has shown promising results for image-guided adaptive radiotherapy in lung, bladder, and esophageal cancer. BioXmark™ is implanted during endoscopy and has appropriate visibility with good positional stability on CT, CBCT, and MRI. Furthermore, no adverse reactions or events have been reported yet. The study will be performed as a feasibility study of BioXmark™ at the Department of Surgery \& Transplantation, Centre of Cancer and Organ Diseases. The investigators plan to include 10 patients who are scheduled to undergo curatively intended surgery for GEJ AC. The patients will be drawn from the existing operating program.
