Background: Preoperative interventions have increased the resectability of colorectal cancer (CRC) liver metastases. This retrospective study compares outcomes after liver resection for bilobar CRC metastases between patients who underwent parenchyma-sparing hepatectomy (PSH), i.e., segmentectomies and smaller resections on both lobes, and those treated with non-PSH, i.e., hemihepatectomy plus any resection on the other lobe. Methods: A cohort of 119 patients who underwent liver resection for bilobar CRC metastases were included...

The aim of the study was to assess apical lymph nodes (APNs) for predicting distant metastases in patients with stage III colorectal cancer (CRC) curatively treated with FOLFOX adjuvant chemotherapy and adequate lymph node retrieval. We investigated the correlation between APN metastasis and clinical outcomes. This retrospective study examined 97 patients. All patients were followed until death, loss to follow-up, or May 2017. Clinicopathological variables, including the APN status, were assessed. Multivariate logistic regression model was used to identify the independent risk factors for APN and distant metastases, and Cox proportional regression model was used to evaluate the association between APN metastasis and oncologic outcomes...

Background and Objective: It is unclear whether early morphological change (EMC) is a predictive marker for regorafenib in metastatic colorectal cancer (mCRC). Therefore, the present study investigated whether EMC can predict the outcome of mCRC patients receiving regorafenib. Results: This study evaluated 68 patients. Among 52 patients with lung metastasis, 16 (31%) had cavity formation (CF). The median progression-free survival (PFS) and overall survival (OS) in patients with/without CF were 4...

The technique of hepatic arterial infusion (HAI) for the treatment of liver metastases from colorectal cancer has been developed over more than 30 years. Although the indications and protocols for this technique have evolved with time, HAI is not routinely performed in clinical practice. Studies have been heterogeneous, with different regimens of intra-arterial drugs, associated or not with systemic chemotherapy, and with unconvincing outcomes. Technical difficulties for catheter placement have limited the implementation of this method in routine practice...

Background: The benefit of hepatic resection in case of concomitant colorectal hepatic and extrahepatic metastases (CHEHMs) is still debatable. The purpose of this study is to assess the results of resection of hepatic and extrahepatic metastases in patients with CHEHMs in a high-volume center for both hepatobiliary and colorectal surgery and to identify prognostic factors that correlate with longer survival in these patients. METHOD: It was performed a retrospective analysis of 678 consecutive patients with liver resection for colorectal cancer metastases operated in a single Centre between April 1996 and March 2016...

Colorectal cancer is a global disease with increasing incidence. Mortality is largely attributed to metastatic spread and therefore, a mechanistic dissection of the signals which influence tumor progression is needed. Cancer stroma plays a critical role in tumor proliferation, invasion and chemoresistance. Here, we sought to identify and characterize exosomal microRNAs as mediators of stromal-tumor signaling. In vitro, we demonstrated that fibroblast exosomes are transferred to colorectal cancer cells, with a resultant increase in cellular microRNA levels, impacting proliferation and chemoresistance...

BACKGROUND: Oral lesions have been reported among the first signs of an undiagnosed metastatic disease. Accurate diagnosis of an occult metastasis remains critical in determining the treatment course. Previous studies regarding oral metastatic tumors present varied data regarding the most frequent metastases to the oral cavity. These discrepancies echo the changes in incidence rates for certain malignancies over time and demonstrate the need for periodic updates in oral metastasis studies...

Colorectal carcinomas (CRC) harbor well-defined genetic abnormalities including aberrant activation of Wnt/β-catenin and MAPK pathways, often simultaneously. While the MAPK pathway can be targeted using potent small molecule drugs, including BRAF and MEK inhibitors, β-catenin inhibition has been historically challenging. RNA interference (RNAi) approaches have advanced to the stage of clinical viability, and are especially well-suited for transcriptional modulators such as β-catenin. In this study, we report therapeutic effects of combined targeting of these pathways with pharmacological agents...

Colorectal cancer (CRC) is driven by the accumulation of driver mutations, but the contributions of specific mutations to different steps in malignant progression is not fully understood. In this study, we generated mouse models harboring different combinations of key CRC driver mutations (Apc, Kras, Tgfbr2, Trp53, Fbxw7) in intestinal epithelial cells to comprehensively investigate their roles in the development of primary tumors and metastases. Apc∆716 mutation caused intestinal adenomas and combination with Trp53R270H mutation or Tgfbr2 deletion induced submucosal invasion...

BACKGROUND: The transmembrane receptor guanylate cyclase-C (GCC) has been found to be expressed in colorectal cancers. However, limited data are available on GCC protein expression in non-colorectal gastrointestinal tumors and few studies have reported whether GCC protein expression was consistently preserved in synchronous primary and metastatic cancer tissues. METHODS: GCC protein status was assessed by immunohistochemistry in tumor specimens from individuals (n = 627) with gastrointestinal tumors, including esophageal (n = 130), gastric (n = 276), pancreatic (n = 136), and colorectal (n = 85) primary and metastatic tumors...

BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy induces an unprecedented liver hypertrophy and enables resection of otherwise unresectable liver tumors. The effect of associating liver partition and portal vein ligation for staged hepatectomy on tumor proliferation, however, remains a concern. This study investigated the impact of associating liver partition and portal vein ligation for staged hepatectomy on growth of colorectal metastases in mice and in humans...

Thermal ablation has been considered as an alternative for local curative intent in patients with unresectable colorectal liver metastases. The influence of primary tumor location on the prognosis of colorectal liver metastases patients who have undergone microwave ablation has yet to be determined. We reviewed 295 patients who underwent microwave ablation for colorectal liver metastases at our institution between March 2006 and March 2016. Univariate and multivariate analyses were performed to identify predictors of overall and progression-free survival...

Cancer research is increasingly dependent of patient-derived xenograft model (PDX). However, a major point of concern regarding the PDX model remains the replacement of the human stroma with murine counterpart. In the present work we aimed at clarifying the significance of the human-to-murine stromal replacement for the fidelity of colorectal cancer (CRC) and liver metastasis (CRC-LM) PDX model. We have conducted a comparative metabolic analysis between 6 patient tumors and corresponding PDX across 4 generations...

INTRODUCTION: Hepatic arterial infusion (HAI) chemotherapy with oxaliplatin is an accepted option in the management of colorectal cancer (CRC) with dominant liver metastases (LM). However, despite prolonged control, some patients experience disease progression. On the other hand, oxaliplatin leads to dose-limiting toxicity. In these cases, the use of a second-line HAI with an alternative drug has never been reported to date. We evaluated treatment outcomes in patients receiving second-line HAI with 5-FU or mitomycin C, after first-line HAI of oxaliplatin in heavily pretreated patients...
