The geographical location and differences in tumor biology significantly change the management of gastric cancer. The prevalence ofgastric cancer ranks fifth and sixth among men and women, respectively, in Turkey. The international guidelines from the Eastern andWestern countries fail to manage a considerable amount of inconclusive issues in the management of gastric cancer. The uncertaintieslead to significant heterogeneities in clinical practice, lack of homogeneous data collection, and subsequently, diverse outcomes.The physicians who are professionally involved in the management of gastric cancer at two institutions in Istanbul, Turkey, organized aconsensus meeting to address current problems and plan feasible, logical, measurable, and collective solutions in their clinical practicefor this challenging disease.The evidence-based data and current guidelines were reviewed. The gray zones in the management of gastric cancer were determinedin the first session of this consensus meeting. The second session was constructed to discuss, vote, and ratify the ultimate decisions.The identification of the T stage, the esophagogastric area, imaging algorithm for proper staging and follow-up, timing and patientselection for neoadjuvant treatment, and management of advanced and metastatic disease have been accepted as the major issues inthe management of gastric cancer.
