The GastroData Study



for detailed information on the GastroData project. The project envisages a Retrospective study (now completed and covering the years 2017 and 2018) and a Prospective study (currently ongoing and covering the years 2019 and 2020).


The findings of our Retrospective study have been published in Annals of Surgery (2020) [click here]:

The GastroData Project: Goals and Steps


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 European Gastric Cancer Association (ECGA) launched the project International Consensus on a Complications List after Gastrectomy for Cancer .


The newly established Gastrectomy Complications Consensus Group (GCCG) comprises 34 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.
