Simultaneous surgery for primary colorectal cancer and metastatic lesions?

• Abstract Approximately 20-25% of patients with colorectal cancer present with liver metastases at the time of diagnosis. Traditionally, resection of the primary tumor has been advocated in order to prevent complications of the primary tumor colorectal cancer in patients with synchronous liver metastases. The published data concerning long-term prognosis in this group of patients are discordant. Although some of the reports show survival benefits from resection of the primary tumor, these studies are retrospective with small number of patients and using single drug chemotherapy. For patients with resectable liver metastases, new studies indicate that progression-free survival is best in patients receiving perioperative chemotherapy. In patients with synchronous nonresectable liver metastases and colorectal cancer, there is no published prospective randomized study comparing initial surgery of the primary tumor with neoadjuvant chemotherapy. However, recent publications show that in patients receiving chemotherapy based on oxaliplatin or irinotecan combined with targeted treatments, the complications associated with the primary tumor are less than 10%. The conclusion should be that today prophylactic surgery of asymptomatic primary colorectal cancer in patients with liver metastases cannot be recommended.
