Brief summary in lay language

The CARDIA study examines malignant tumors located directly at the transition between the esophagus and stomach. By surgically removing the tumour, this cancer can be cured in some of the affected patients. There are currently two possible surgical procedures. One procedure is the transthoracic oesophagectomy with stomach elevation. During this procedure, a large part of the oesophagus is removed together with the oesophageal-gastric-transition. The stomach is then formed into a tube and connected to the rest of the esophagus in the chest cavity. The other operation is the transhiatal extended gastrectomy. In this procedure, the stomach is removed together with the oesophageal-gastric-transition. A connection is then created between the esophagus and a part of the small intestine. Both procedures allow complete removal of the tumor. However, they are associated with different risks and complications. So far, it has not been possible to determine scientifically which of the two operations is better suited for the treatment of transitional tumors. The aim of this clinical study is therefore to compare the two procedures in terms of healing rates and the resulting quality of life.

Brief summary in scientific language

Adenocarcinomas of the gastroesophageal Junction (GEJ) type II can be resected either by transthoracic oesophageectomy or transhiatal extended gastrectomy. Both surgical procedures allow a complete tumor resection. To date, it has not been determined which surgery is superior in terms of quality of life, oncological outcome and survival, as only retrospective studies with contradictory results have been conducted so far. The CARDIA trial compares both surgical procedures in a non-blinded, multinational, multicenter, prospectively randomized study design. Patients with an GEJ type II tumor that can be resected by both transthoracic esophagectomy and transhiatal gastrectomy will be enrolled in the trial and will be operated after randomization using one of the investigated surgical procedure. Primary endpoint is overall survival. Secondary endpoints are complete resection (R0), number and location of tumor-infiltrated lymph nodes, postoperative complications, disease-free survival, quality of life and cost-effectiveness. Postoperative survival, disease-free survival and quality of life are monitored for 24 months after discharge. Overall survival is then monitored through quarterly telephone calls up to 60 months after surgery.
