International Survey on Tumor Regression Grading Systems for Gastrointestinal Carcinomas
This is an international survey being sent out to pathologists in multiple nations with special interest in GI. In this way, we hope to achieve a broad, world-wide view about the usage of tumor regression grading (TRG) for post-neoadjuvant treated gastrointestinal carcinomas (i.e. esophageal, gastric and rectal cancer) in daily practice and capture opinions regarding critical issues in grading. The results of this survey may help to work out a more standardized way to report on therapy induced changes in GI carcinomas. It should take less than 10 minutes to fill out. Your contribution is highly appreciated and we hope that the results of this study will provide valuable information about this topic.
