diagnosis
Follow up plan

25
• Locally advanced rectal cancer with synchronous multiple liver only metastatic disease
• Multidisciplinary discussion essential for all rectal cancer cases: at start and during treatment or follow up
• Do not miss any opportunities for your patients
• 5x5 Radiation plus CT may induce clinical CRs
• After chemotherapy, liver resection recommended if mets become resectable
• Surveillance of the primary tumor as an emerging option
• So far successful multimodality treatment
