Validation of the Data Quality and Early Outcomes of the Spanish EURECCA Esophagogastric Cancer Registry

Objective. The objective of the study is to verify and validate the data collected in the Spanish EURECCA (EUropean REgistry of Cancer CAre) Esophagogastric Cancer Registry between January 2014 and December 2017 through an audit process. It is also intended to describe the initiation and implementation of this Registry as well as its early outcomes.

Methods. An audit of registered cases (esophageal, esophagogastric junction and gastric cancer resectable patients undergoing surgery) from 01/01/2014 to 12/31/2017 and a descriptive analysis of these data will be performed.

Expected results. The study could show that the Spanish EURECCA Esophagogastric Cancer Registry is a reliable source of information, valid for carrying out specific and exhaustive analysis that may lead to high quality publications in indexed journals. It is also expected to generate a high impact based on the large number of cases included in the Registry, favoring new research projects.

Relevance. The standardization of the data collection is essential to compare outcomes between different centers, regions and countries. This study will allows us to verify the integrity of the collected data as well as its accuracy, a critical aspect to gain credibility for future studies using the Registry data.
