Gastrectomy Complications Consensus Group (GCCG)



for detailed information on this multicenter international study and the description of the newly developed Gastrectomy Complications Recording Sheet.


Perioperative complications influence long- and short-term outcomes after gastrectomy for gastric cancer. The absence of a standardized system for defining and recording complications and quality measures after gastric resection has generated a wide variation in evaluating their impact on critical outcomes such as mortality, morbidity, early cancer recurrence, survival, readmission rates, length of hospital stay, costs and resource utilization, and quality of life.


To address this issue, in 2015 a group of European surgeons belonging to the International Gastric Cancer Association (ICGA) launched the project International Consensus on a Complications List after Gastrectomy for Cancer by appointing as Principal Investigators


Gian Luca Baiocchi, University of Brescia and Spedali Civili di Brescia

The newly established Gastrectomy Complications Consensus Group (GCCG) comprises the 3 PIs and 31 specialist gastric cancer surgeons from 13 European countries reflecting different health systems. Delphi surveys and group meetings were used to achieve a consensus on stardardized methods for defining complications and quality measures that can be collected in institutional databases and national audits.


In 2017, the first step of the project has delivered a consensus on a comprehensive list of items, including the name and definition of each complication. The proposed list of 27 defined complications, published in Gastric Cancer (2018, click here to download the article), represents the first step in developing an essential clinical tool for postoperative assessment of gastric cancer patients.


We are currently collecting data for the retrospective study using an electronic Datasheet developed by the software firm Fluxedo in Italy and described in the GCCG web site


In the next step, the GCCG will become a fully international group with specialist gastric cancer surgeons from Brazil, China, Japan, Korea, and the United States joining the project.
