To obtain a better patient selection, the authors have suggested the initial realization of systemic chemotherapy in the circumstance of patients with colorectal tumor stage Ⅳ, since these patients have a systemic disease. The rationale behind this liver-first strategy is initially the control of synchronous hepatic metastases of colorectal carcinoma, which can optimize a potentially curative hepatic resection and longstanding survival. The liver-first strategy procedure is indicated for patients with colorectal hepatic metastases who require downstaging therapy to make a curative liver resection possible.
