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
