PURPOSE: Heterogeneity is a key feature of malignancy associated with adverse tumor biology. Texture analysis with different imaging modalities has been shown to reflect tumor heterogeneity. The current study analyzed and compared pre-treatment (contrast-enhanced) ceCT and positron emission tomography/computed tomography (PET/CT) tumor heterogeneity using the parameters skewness and kurtosis in patients with primary colorectal cancer with and without liver metastases. PROCEDURES: The histogram-derived texture parameters skewness and kurtosis were retrospectively analyzed obtained on PET/CT and ceCT images from 50 patients with histopathology proven primary colorectal cancer (32 patients without liver metastases and 18 with liver metastases)...

The optimal surgical strategy for treating colorectal cancer with synchronous liver metastases is subject to debate. The current study sought to evaluate the outcomes of simultaneous colorectal cancer and liver metastases resection in a single center. Prospectively collected data on all patients with synchronous colorectal liver metastases who underwent simultaneous resection with curative intent were analyzed retrospectively. Patient outcomes were compared depending on the primary tumor location and type of liver resection (major or minor)...

The role of physical interventions (surgical resection and surgical/radiological ablation) for liver metastases of colorectal cancer has changed dramatically over the last 10-15 years. Whereas in the 1990s, when only those patients with up to three unilobar metastases were considered for any form of such intervention, our present approach to these physical interventions is determined by how much viable disease-free liver can be preserved (most authorities accepting 25-30% disease-free future remnant liver volume) and the possibility of further such interventions if the disease recurs in the liver...

BACKGROUND: Tumor-associated macrophages (TAMs) support growth in most human cancers, with the notable exception of colorectal adenocarcinoma, in which TAM infiltration of primary tumors is correlated with a better outcome. The importance of TAMs in colorectal liver metastases (CLM) is unknown. METHODS: Using a tissue microarray of CLM resected at their institution from 1998 to 2000, the authors quantified immune marker expression by immunohistochemistry (IHC) using Metamorph Image Analysis software...

INTRODUCTION: A potentially resectable bony metastasis in the context of oligometastatic colorectal cancer is uncommon. Bony metastases are usually considered a late event with poor prognosis and generally associated with liver and/or lung metastases. INDEX CASE: A previously healthy 33-year-old gentleman, with no family history of colorectal cancer, presented with rectal bleeding and at colonoscopy had a biopsy-proven adenocarcinoma of the rectum, 7 cm from the anal verge...

This study aimed to determine the prognostic effects of preoperative chemotherapy for colorectal cancer liver metastasis (CLM).We retrospectively evaluated 2 groups of patients between January 2006 and August 2012. A total of 53 patients who had ≥3 hepatic metastases underwent resection after preoperative chemotherapy (preoperative chemotherapy group), whereas 96 patients who had ≥3 hepatic metastases underwent resection with a curative intent before chemotherapy for CLM (primary resection group). A propensity score (PS) model was used to compare the both groups...

OBJECTIVE: The aim of this study was to compare adhesion formation after laparoscopic and open colorectal cancer resection. SUMMARY OF BACKGROUND DATA: After colorectal surgery, most patients develop adhesions, with a high burden of complications. Laparoscopy seems to reduce adhesion formation, but evidence is poor. Trials comparing open- and laparoscopic colorectal surgery have never assessed adhesion formation. METHODS: Data on adhesions were gathered during resection of colorectal liver metastases...

Metastases are the most common malignant lesions of the liver. The presence of liver metastases is an important prognostic factor and is decisive for the further management, especially in patients with colorectal cancer. Detection and characterization of liver metastases as well as differentiation from benign lesions are of high importance and a daily challenge in clinical radiology. Contrast-enhanced magnetic resonance imaging (MRI) has the highest sensitivity in detecting liver metastases. The sensitivity of MRI has been further increased due to the development of liver-specific contrast agents...

PURPOSE: Surgical resection of isolated hepatic or pulmonary metastases of colorectal cancer is an established procedure, with a 5-year survival rate of about 50%. However, the role of surgical resections in patients with both hepatic and pulmonary metastases is not well established. We aimed to analyze overall survival of these patients and associated factors. METHODS: Data retrospectively collected from 66 patients who underwent both hepatic and pulmonary metastasectomy after colorectal cancer surgery from August 2002 through August 2013 were analyzed...

Liver transplantation is an option that improves quality of life and prolongs life expectancy in patients with different types of liver disease. Liver transplantation is controversial for colorectal metastases and is not recommended in clinical practice guidelines. In this case report, we present, to our knowledge, the first liver transplantation for colorectal metastases conducted in Colombia, with a successful follow-up of more than 2 years. Patients with these characteristics who underwent liver transplantation experience reduced mortality and exponentially improved quality of life...

EGFR-targeted therapy is a key treatment approach in patients with RAS wildtype metastatic colorectal cancers (CRC). Still, also RAS wildtype CRC may be resistant to EGFR-targeted therapy, with few predictive markers available for improved stratification of patients. Here, we investigated response of 7 CRC cell lines (Caco-2, DLD1, HCT116, HT29, LS174T, RKO, SW480) to Cetuximab and correlated this to NGS-based mutation profiles, EGFR promoter methylation and EGFR expression status as well as to E-cadherin expression...

BACKGROUND: Laparoscopic resection of posterosuperior (PS) segments of the liver is hindered by limited visualization and curvilinear resection planes. The aim of this study was to compare outcomes after open and laparoscopic liver resections of PS segments. METHODS: Patients who underwent minor open liver resection (OLR) and laparoscopic liver resection (LLR) between 2006 and 2014 were identified from the institutional databases of seven tertiary referral European hepatobiliary surgical units...

BACKGROUND: Isolated liver metastases occur rarely in patients with metastatic breast cancer. The success of liver resection (LR) for other metastatic disease has led centres to explore the option of LR for patients with isolated breast cancer liver metastases (BCLM). A number of small series have been published in the literature, however the evidence is conflicting. This study aimed to systematically review the literature to determine the perioperative outcome and survival of patients undergoing LR for BCLM...

BACKGROUND: For patients with colorectal liver metastases (CLM) undergoing major hepatectomy, extensive preoperative chemotherapy has been associated with increased morbidity and mortality. The impact of extensive chemotherapy on total liver volume (TLV) change is unclear. METHODS: Clinicopathological features of patients with CLM who underwent preoperative chemotherapy and curative resection were reviewed (2008-2015). TLV change (degree of atrophy) was defined as the percentage difference of TLV (estimated by manual volumetry)/standardized liver volume (SLV) ratio: ([Pre-chemotherapy TLV] - [Post-chemotherapy TLV]) × 100 ÷ SLV (%)...

Liver transplantation is an effective treatment for many liver diseases, with a 5-year survival of about 70 %. However, development of de novo malignancies in these immunocompromised patients is becoming a frequent complication medium term. The annual risk of developing a malignant tumor after a solid organ transplant is 2% . We report the case of a liver transplant patient who developed colorectal neoplasia at 12 years after transplantation , and then a metachronous metastases in the liver transplanted.
