Approximately 50% of colorectal cancer Surgical resection is the standard therapy (CRC) patients develop liver metastases for resectable liver disease, resulting in during the course of their disease, and 5-year overall survival rates of 20-40%. more than 50% of patients who die of CRC One the other hand, the median overall have liver metastases at autopsy. Regional survival of patients with unresectable liver lymph node (RLN) involvement in patients metastases does not exceed 18-20 months, with colorectal liver metastases is one with a 5-year survival rate approaching of the worst prognostic factors. Recent zero. In other words, there is virtually no studies indicate that for these patients, long-term survival. Both resectable and combined liver resection and pedicular unresectable liver cancers are discussed lymphadenectomy can be recommended, in this volume.
