Complete clinical response of liver metastasis after chemotherapy: To resect or not?

This paper aims to update the therapeutical strategies in liver metastasis with complete clinical response (CCR) after chemotherapy and to determine if surgery is always necessary after CCR. The aim of chemotherapy is to achieve a good clinical response rather than CCR of liver metastasis. The CCR of liver metastasis after chemotherapy cannot be considered synonymous with a cure. The resection of the hepatic segment where there was hepatic metastases with CCR after chemotherapy theoretically prevents recurrence, improves survival and makes it possible to confirm whether there has been a complete pathological response. However, the medical literature about this topic is scarce and sometimes contradictory.
