Pathological response to preoperative chemotherapy was recently found to be correlated with improved survival and has been proposed as a new outcome end-point following resection of liver metastases from colorectal cancer (CRC). It was demonstrated that, particularly after therapy with bevacizumab, CRC liver metastases decreased in size and underwent distinct morphological changes on computed tomography (CT). However, morphological changes in response to treatment with regorafenib have not yet been reported...

Up to three-quarters of patients undergoing liver resection for colorectal liver metastases (CRLM) develop intrahepatic recurrence. Repeat hepatic resection appears to provide the optimal chance of cure for these patients. The aim of this study was to analyze short- and long-term outcomes following index and repeat hepatectomy for CRLM. Clinicopathological data were obtained from a prospectively maintained database. Perioperative variables and outcomes were compared using the Chi-squared test. Variables associated with long-term survival following index and second hepatectomy were identified by Cox regression analyses...

Colorectal cancer is a prevalent malignancy worldwide, and investigations are required to elucidate the underlying carcinogenic mechanisms. Amongst these mechanisms, de novo carcinogenesis and the adenoma to carcinoma sequence, are the most understood. Metastasis of colorectal cancer to the liver often results in fatality, therefore, it is important for any associated risk factors to be identified. Regarding the treatment of the disease, it is important to manage not only the primary colorectal tumor, but also the liver metastases...

Despite rare, metastatic anal carcinoma confers a poor prognosis. Systemic chemotherapy is the mainstay of treatment for advanced disease while the role of biologics and/or surgical resection of metastatic disease are anecdotal. Compared to isolated liver colorectal or neuroendocrine cancer liver metastases, there is far less experience with resection or nonsurgical local ablative procedures for patients with metastatic anal carcinoma to the liver. We report the case of a 67-year-old woman with metastatic anal carcinoma to the liver who was successfully treated with liver resection and remains free of relapse more than one year later...

Breast cancer is the leading cause of cancer-related mortality in women worldwide. Liver metastasis is involved in upwards of 30% of cases with breast cancer metastasis, and results in poor outcomes with median survival rates of only 4.8 - 15 months. Current rodent models of breast cancer metastasis, including primary tumor cell xenograft and spontaneous tumor models, rarely metastasize to the liver. Intracardiac and intrasplenic injection models do result in liver metastases, however these models can be confounded by concomitant secondary-site metastasis, or by compromised immunity due to removal of the spleen to avoid tumor growth at the injection site...

PURPOSE: The purpose of this study was to assess hepatic arterial infusion (HAI) of oxaliplatin combined with intravenous 5-fluorouracil (5-FU) and l-leucovorin (l-LV) in colorectal cancer (CRC) patients with systemic chemotherapy failure in a phase I/II trial. METHODS: CRC patients with unresectable liver metastases following standard systemic chemotherapy failure were eligible. A catheter-port system for HAI was placed using interventional radiology. In phase I, escalating doses of oxaliplatin for levels 1 and 2 were set at 50 and 100 mg/m(2), respectively, and were combined with fixed doses of intravenous 5-FU (200 mg/m(2) bolus and 2400 mg/m(2)/46-h continuous infusion) and l-LV (200 mg/m(2))...

BACKGROUND: While the indications for surgery among patients with colorectal cancer liver metastases (CRCLM) are expanding, the role of surgery in patients with hepatic lymph node involvement remains controversial. We report management and outcomes in a population-based cohort of patients undergoing hepatectomy with concomitant hepatic lymphadenectomy for CRCLM. METHODS: All cases of hepatectomy for CRCLM in the Canadian Province of Ontario from 2002 to 2009 were identified using the population-based Ontario Cancer Registry and linked electronic records of treatment...

BACKGROUND: Colorectal cancer (CRC) often presents as oligometastatic disease. Currently available intensive systemic treatment regimens, including combination chemotherapy and molecular targeted agents, result in tumor response and transient to long-term disease control in a high percentage of patients, thus raising the question of further management. Secondary resection and ablation, e.g. by surgery or radiofrequency may contribute to long-term survival and even be curative or at least allow a relevant chemotherapy-free interval...

OBJECTIVE: Clinical trials demonstrated that 6-37% of the patients with colorectal liver-limited metastases underwent surgical resection after first-line chemotherapy. However, limited information is available on the conversion of colorectal cancer patients with lung metastases to resection by systemic chemotherapy. METHODS: We retrospectively investigated 156 patients with unresectable colorectal cancer who received oxaliplatin- or irinotecan-based first-line systemic chemotherapy with or without antibodies in our department between January 2007 and December 2015...

PURPOSE: To quantify the impact of 4D PET/CT on PERCIST metrics in lung and liver tumors in NSCLC and colorectal cancer patients. METHODS: 32 patients presenting lung or liver tumors of 1-3 cm size affected by respiratory motion were scanned on a GE Discovery 690 PET/CT. The bed position with lesion(s) affected by motion was acquired in a 12 minute PET LIST mode and unlisted into 8 bins with respiratory gating. Three different CT maps were used for attenuation correction: a clinical helical CT (CT_clin), an average CT (CT_ave), and an 8-phase 4D CINE CT (CT_cine)...

BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) allows the resection of colorectal liver metastases with curative intent which would otherwise be unresectable and only eligible for palliative systemic therapy. This study aimed to compare outcomes of ALPPS in patients with otherwise unresectable colorectal liver metastases with matched historic controls treated with palliative systemic treatment. METHODS: All patients with colorectal liver metastases from the international ALPPS registry were identified and analyzed...

Assessing circulating tumor DNA (ctDNA) is a promising method to evaluate somatic mutations from solid tumors in a minimally-invasive way. In a group of twelve metastatic colorectal cancer (mCRC) patients undergoing liver metastasectomy, from each patient DNA from cell-free DNA (cfDNA), the primary tumor, metastatic liver tissue, normal tumor-adjacent colon or liver tissue, and whole blood were obtained. Investigated was the feasibility of a targeted NGS approach to identify somatic mutations in ctDNA. This targeted NGS approach was also compared with NGS preceded by mutant allele enrichment using synchronous coefficient of drag alteration technology embodied in the OnTarget assay, and for selected mutations with digital PCR (dPCR)...

Purpose Colorectal cancer (CRC) treatment is largely determined by tumor stage. Despite improvements made in the treatment of various types of metastatic disease, staging has not been refined. The role of tumor deposits (TDs) in staging remains debated. We have assessed the relation of TDs with metastatic pattern to evaluate whether TDs might add significant new information to staging. Methods We performed a systematic literature search that was focused on the role of TDs in CRC. Studies with neoadjuvant-treated patients were excluded...

BACKGROUND: The presence of circulating tumor cells (CTC) has been reported in patients with advanced colorectal cancer. Monitoring CTC (also known as a liquid-biopsy) has recently become the center of interest for low-invasive monitoring of cancer progression and predictive biomarkers testing. Along with high-cost technology and a complex methodology, a straightforward method based on magnetic beads enrichment followed by RT-PCR is set to allow for routine CTC analysis in colorectal cancer patients...
