Prospective Observational Study of Peritoneal Surface Malignancies (PSM) - Characterization, Models and Treatment Strategies.

The handling of patients with PSM involves multimodal and multidisciplinary treatment strategies such as CRS, the removal of all macroscopically detectable tumor, and HIPEC, instillation of heated chemotherapy in the abdominal cavity to remove residual cancer disease. The treatment is challenging and complex and associated with significant morbidity. Only patients with limited disease will benefit from the treatment, and better methods for patient selection are needed. The project group has a unique opportunity to address key questions because of acquired experience, an exceptional biobank and institutional database and novel animal models established at the Norwegian Radium Hospital.
