ABSTRACT The surgical strategy for treatment of synchronous liver metastases from colorectal cancer remains controversial. This retrospective analysis was conducted to compare the postoperative outcome and survival of patients receiving simultaneous resection of liver metastases and primary colorectal cancer to those receiving staged resection.
Between January 1988 and September 2005, 219 patients underwent liver resection for synchronous colorectal liver metastases, of whom, 40 patients received simultaneous resection of liver metastases and primary colorectal cancer, and 179 patients staged resections. Patients were identified from a prospective database, and records were retrospectively reviewed. Patient, tumor, and operative parameters were analyzed for their influence on postoperative morbidity and mortality as well as on long-term survival.
Simultaneous liver resections tend to be performed for colon primaries rather than for rectal cancer (p = 0.004) and used less extensive liver resections (p < 0.001). The postoperative morbidity was comparable between both groups, whereas the mortality was significantly higher in patients with simultaneous liver resection (p = 0.012). The mortality after simultaneous liver resection (n = 4) occurred after major hepatectomies, and three of these four patients were 70 years of age or older. There was no significant difference in long-term survival after formally curative simultaneous and staged liver resection.
Simultaneous liver and colorectal resection is as efficient as staged resections in the treatment of patients with colorectal cancer and synchronous liver metastases. To perform simultaneous resections safely a careful patient selection is necessary. The most important criteria to select patients for simultaneous liver resection are age of the patient and extent of liver resection.

    ABSTRACT: Optimal management of synchronous colorectal liver metastases demands a well-organized inter-disciplinary strategy by surgeon, oncologist and radiologist. Over the past decade, advances in management strategies of patient with liver-limited metastases have incredibly improved the overall prognosis. This review discusses the advances made in the management of patients with colorectal cancer liver metastases. A literature search was performed, using the following databases: PubMed, SCOPUS sciencedirect, EMBASE, and NHS Knowledge Network. The retrieved articles were assessed for relevance for inclusion in this review. The review illustrates that although currently surgery offers the best chance of cure in patients with colorectal liver metastases, the majority of patients are not initially resectable due to the size, anatomic location, extent of disease, inadequate remnant liver volume, or comorbidities. This necessitates other treatment modalities to control or downsize the hepatic lesions before embarking on the surgical intervention. Systemic and regional chemotherapy complements the surgical cure in the majority of patients.

    ABSTRACT: The optimal timing of resection for synchronous colorectal liver metastases is still controversial. Retrospective cohort studies always had baseline imbalances in comparing simultaneous resection with staged strategy. Significantly more patients with mild conditions received simultaneous resections. Previous published meta-analyses based on these studies did not correct these biases, resulting in low reliability. Our meta-analysis was conducted to compensate for this deficiency and find candidates for each surgical strategy.

    ABSTRACT: The management of synchronous presentation of colorectal cancer and liver metastases has long been a topic of debate and discussion for surgeons due to the unique dilemma of balancing operative timing along with treatment strategy. Operative strategies for resection include staged resection with colon first approach, "reverse" staged resection with liver metastases resected first, and one-stage, or simultaneous, resection of both the primary tumor and liver metastases approach. These operative strategies can be further augmented with perioperative chemotherapy and other novel approaches that may improve resectability and patient survival. The decision on operative timing and approach, however, remains largely dependent on the surgeon's determination of disease resectability, patient fitness, and the need for neoadjuvant chemotherapy.
