2 Learning objectives All patients with liver limited or oligometastatic disease have a potential chance for cure A multidisciplinary aproach is essential The clinical presentation may be considered as Resectable, boarderline resectable, potentially resectable after chemotherapy In resectable disease surgery alone or following chemotherapy are options In boarderline and unresectable disease the most effective and still tolerable chemotherapy according to the molecular profile should be used within a multidisciplinary context Even if surgery might not be curative it extends overall survival and can be considered as a further line of chemotherapy or a form of maintenance chemotherapy

5 Liver limited disease: Patient groups Clearly resectable Borderline resectable Definitely NOT resectable

6 Resectable LLD but high risk of recurrence Fong Score Primary tumor N + DFI < 12 Monate > 1 Metastasis > 5 cm CEA > 200 ng/ml >12cm Age 51y Rectal Adeno-Ca: ct3, N+ Synchroneous LLD, ø 12 cm CEA 568 ng/ml High Fong Score Estimated 5y < 10%

7 Group 0 Resectable metastases Primary tumor N + DFI < 12 Monate > 1 Metastasis > 5 cm CEA > 200 ng/ml Fong score > 2 Disease specific survival (DSS)

10 Conclusions resectable & boarderline resectable disease Resectable : Perioperative Chemotherapy questionable Boarderline : no restrictions in Chemo regimens including use of EGFR

12 Response and resection rates within trials Trials with neoadjuvant focus Trials with palliative focus CRC Give the most active (RR) regimen still tolerable by the patient Folprecht G.Köhne CH et al. Ann Oncol 2005; Jones R et al. Eur J Cancer, 2014

13 Tumor load at Baseline Morbidity ESMO acknowledges response parameters like early tumor shrinkage (ETS) or depth of response (DpR) for conversion therapy Fire-3 data Lethal tumor load OS No CT =<5 cycles 6-9 cycles =>10 cycles ETS Tumor nadir PFS Time since start of treatment Steatohepatitis Karoui Nordlinger et al, Ann.Surg Sinusoidal distention Vauthey et al.
