Adjuvant Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) in Resected High Risk Colon Cancer Patients

Summary

In this study, patients will be offered two Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC) treatments with oxaliplatin after primary resection and standard adjuvant chemotherapy (if indicated) for colon cancer. Furthermore, the study will explore, whether it is possible to find free intraperitoneal tumor cells (FITC) after resection and adjuvant chemotherapy for colon cancer.
