Colorectal liver metastases (CRLM) present an important clinical challenge in both surgical and medical oncology. Despite improvements in management, survival among patients undergoing resection of CRLM is still very variable and there is a paucity of clinical trial data and reliable biomarkers that could guide prognostic forecasts, treatment selection, and follow-up. Fortunately, recent advances in molecular biology and tumor sequencing have identified a number of critical genetic loci and proliferation markers that may hold the key to understanding the biologic behavior of CRLM; specifically, mutations of KRAS, BRAF, TP53, PIK3CA, APC, expression of Ki-67, and the presence of microsatellite instability appear to have a decisive impact on prognosis and response to treatment in patients with CRLM...

Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) has expanded the surgical armamentarium for patients with advanced and bilateral colorectal liver metastases. However, the enthusiasm that the medical fraternity had about ALPPS was hampered by a high mortality rate and early and frequent tumor recurrence. While surgical safety has improved, mainly due to technical refinements and a better patient selection, the oncological value in the face of early tumor recurrence remains unclear...

BACKGROUND: The Kallikrein-Kinin System (KKS) has been found to play a role in tumor progression in several cancers. The KKS metabolic cascade depends on signalling through two cross talking receptors; bradykinin receptor 1 (B1R) and bradykinin receptor 2 (B2R). Activation of the Kinin receptor is responsible for multiple pathophysiologic functions including increase of vascular permeability and induction of host inflammatory responses that exert diverse effects on tumor growth. METHODS: B1R and B2R expression on mouse and human CRC cell lines was investigated...

BACKGROUND: Colorectal cancer is common, and its incidence is increasing throughout the world. The liver is a major metastatic site, and colorectal liver metastasis (CRLM) has a poor prognosis. Although liver resection is the most effective therapy for CRLM, postoperative recurrence is common. Thus, prognostic markers for CRLM are greatly needed. D-dimer, a fibrin cleavage product, has been shown to be related to colorectal tumor progression, and is also associated with malignant progression and recurrence in various cancers...
