Hyperthermic Intraperitoneal Chemoperfusion (HIPEC) in Gastric Cancer

描述
An operation and the constant further development of the surgical techniques can not always prevent the recurrence of a tumor of the stomach or the transition from the esophagus to the stomach. As reason for this recurrence, the investigators assume that the tumor was already present at the time of the surgery and has crossed the boundaries of the stomach or free tumor cells are located in the peritoneal cavity, even if they can't be found with the bare eye or imaging methods. Such free tumor cells have the possibility of developing metastases within the abdominal cavity.
An innovative local treatment method is being tested in Tübingen and applied to remove any remaining free tumor cells or very small and invisible residual tumors. These free tumor cells can be determined prior to the start of treatment by peritoneal endoscopy (diagnostic laparoscopy). If these can be identified by lavage of the abdominal cavity there is an increased risk for the development of peritoneal metastases. Therefore, in patients with detected free tumor cells in the lavage water of the abdominal cavity, after the removal of the stomach, should be used once a chemotherapy in the abdominal cavity, which is warmer than the body (intraoperative hyperthermic chemotherapy, HIPEC). In this study the investigators want to demonstrate, that the single administration of intraoperative HIPEC with cisplatin and doxorubicin in addition to routine surgery delays the onset of peritoneal metastases and the additional therapy with its low risks is reasonable.
