INTRODUCTION: Resection of both liver and lung metastases from colorectal carcinoma (CRC) is a standard of care in selected patients with oligometastatic disease. We present here the analysis of the subgroup of patients undergoing combined surgery from the Spanish Group of Surgery of Pulmonary Metastases (PM) from Colorectal Carcinoma (GECMP-CCR-SEPAR). METHODS: We analyze characteristics, survival and prognostic factors of patients undergoing combined resection from March-2008 to February-2010 and followed-up during at least 3 years, from the prospective multicenter Spanish Registry...

The association between mutations of key driver genes and colorectal cancer (CRC) metastasis has been investigated by many studies. However, the results of these studies have been contradictory. Here, we perform a comprehensive analysis to screen key driver genes from the TCGA database and validate the roles of these mutations in CRC metastasis. Using bioinformatics analysis, we identified six key driver genes, namely APC, KRAS, BRAF, PIK3CA, SMAD4 and p53. Through a systematic search, 120 articles published by November 30, 2017, were included, which all showed roles for these gene mutations in CRC metastasis...

AIM: Extraperitoneal rectal resection combined with complete peritonectomy of the pelvis in patients with peritoneal metastases is associated with a high rate of morbidity and mortality due to anastomotic leakage (AL). Therefore, many centers tend to perform loop ileostomy to reduce the clinical impact of AL. The aim of this study was to analyze the need for protective stoma creation in this patient group to avoid major complications and mortality in the case of AL. METHOD: We analyzed 53 patients who underwent extraperitoneal rectal resection from 409 consecutive patients treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) at our department between January 1997 and December 2016...

BACKGROUND: Scoring systems were developed to stratify patients with colorectal liver metastases considered for liver resection into different risk groups. Such scores have never been evaluated in recurrent liver metastases. The aim of this study was to evaluate whether these scores are applicable to patients with recurrent colorectal liver metastases and treated with curative intent. METHODS: We retrospectively analyzed data from 375 consecutive patients who underwent liver surgery for colorectal liver metastases between June 2010 and August 2015...

Progression of solid cancers, colorectal carcinomas among them, from their primaries to metastatic lesions traditionally is thought to proceed by a step-wise acquisition of and selection for genomic aberrations. To test if patterns of genomic aberrations would be consistent with this model, we studied ten colorectal carcinoma primary-metastasis pairs, nine with one liver metastasis each, and one with two metastases. Next generation targeted sequencing (50 gene panel) with samples obtained from different regions of the primaries and their metastases demonstrated 1-11 gene mutations per lesion...

BACKGROUND: Bone metastases commonly occur in conjunction with solid tumors, and are associated with serious bone complications. Population-based estimates of bone metastasis incidence are limited, often based on autopsy data, and may not reflect current treatment patterns. METHODS: Electronic medical records (OSCER, Oncology Services Comprehensive Electronic Records, 569,000 patients, 52 US cancer centers) were used to identify patients ≥18 years with a solid tumor diagnosis recorded between 1/1/2004 and 12/31/2013, excluding patients with hematologic tumors or multiple primaries...

BACKGROUND: Performance status (PS) is known as one of the strongest prognostic factors for survival in metastatic colorectal cancer patients. The aim of the present study was to analyze factors associated with poor PS assessed after resection for colorectal liver metastases and the impact on survival. METHODS: All patients undergoing curative resection for colorectal liver metastases between 2010 and 2015 in a single center were reviewed retrospectively. RESULTS: A total of 284 patients were included, out of whom 74 patients (26%) presented with a postoperative PS WHO > 2 precluding administration of adjuvant chemotherapy...

Most currently available colorectal cancer (CRC) mouse models are not suitable for studying progression toward the metastatic stage. Recently, establishment of tumor organoid lines, either from murine CRC models or patients, and the possibility of engineering them with genome-editing technologies, have provided a large collection of tumor material faithfully recapitulating phenotypic and genetic heterogeneity of native tumors. To study tumor progression in the natural in vivo environment, we developed an orthotopic approach based on transplantation of CRC organoids into the cecal epithelium...

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: Hepatic malignancies are common including primary malignancies and metastases. Transarterial radioembolization (TARE) is an important treatment option. We reviewed safety and efficacy of (TARE) in our patients to identify factors that may impact treatment outcomes in a heterogeneous population. Methods: All patients that received TARE at the Medical University of South Carolina from March 2006 through May of 2014 were included. Kaplan-Meier estimates on overall survival (OS) from date of first procedure are reported...

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...

Colorectal cancer (CRC) is heterogeneous and contains different-sized cells. Recent studies have shown that tumor-initiating cells (TICs) are involved in cancer initiation, recurrence and metastasis. However, connections between cancer cell size and stem-like properties are largely unknown. Here we purified large- and small-sized CRC cells by fluorescence-activated cell sorting (FACS) based on forward scatter (FSC), and demonstrated that small CRC cells possess higher holoclone- and sphere-forming capacity in vitro, tumor-initiating capacity in vivo and form more lung metastases compared with large CRC cells...

Despite significant advances have been achieved in the genetic characterization of sporadic colorectal cancer (sCRC), the precise genetic events leading to the development of distant metastasis remain poorly understood. Thus, accurate prediction of metastatic disease in newly-diagnosed sCRC patients remains a challenge. Here, we evaluated the specific genes and molecular pathways associated with the invasive potential of colorectal tumor cells, through the assessment of the gene expression profile (GEP) of coding and non-coding genes in metastatic (MTX) vs...
