Following the PIPAC procedure, patients are monitored with a multidisciplinary approach by the oncology department, depending on the tumor's localization. This follow-up process includes regularly performed blood tests and imaging methods such as tomography, MRI, or PET/CT. A diagnostic laparoscopy may be planned 4 months later to evaluate specific markers placed during the operation. Additionally, a comprehensive PET/CT scan is conducted 6 months thereafter.
