PURPOSE: Efficacy and the frequency of tumor cavitation have not been investigated in patients with metastatic colorectal cancer (mCRC) and lung metastases (LMs) treated with chemotherapy in combination with bevacizumab. This study was aimed to evaluate the efficacy and safety of bevacizumab for unresectable mCRC with LM and to determine the frequency of tumor cavitation, and its correlation with clinical outcomes in patients receiving bevacizumab plus chemotherapy. METHODS: Patients with mCRC and LMs treated with bevacizumab as first- or second-line therapy at West China Hospital, Sichuan University Cancer Center from September 2010 to November 2016 were included in this retrospective study...

S Beckert, A Königsrainer
There is an increasing role of surgery even in metastatic tumor stages. In colorectal cancer patients with limited metastases, complete cytoreduction is able to offer long-term survival in synchronic as well as metachronic situations. In tumors of the upper gastrointestinal tract (UGIT), however, the impact of surgery in metastatic disease remains to be clarified. Even though several retrospective studies suggest prolonged survival, surgery is not recommended by the current German S3 guidelines for tumors of the UGIT...

Due to significant improvements in morbidity and mortality, surgery with curative intent is now the standard of care for patients with colorectal liver metastases who are surgical candidates. As a result, highly accurate preoperative per-lesion diagnosis is crucial. However, in some instances, this remains limited with standard techniques, including magnetic resonance imaging (MRI) with conventional contrast agents. Delayed retention of contrast of fibrotic liver metastases on MRI with extracellular contrast agents may mimic the late retention of contrast in hemangiomas and represent a diagnostic pitfall that limits diagnosis...

Effective individualized treatment of patients with colorectal liver metastases (CLM) requires tumor genotyping, usually based on the analysis of one single sample per patient. Therapy failure may partially be explained by sampling errors and/or intratumoral genetic heterogeneity. We aimed to demonstrate intratumoral genetic heterogeneity in CLM and enable pathologists to select tumor tissue for genotyping. All the tumors of 86 patients who underwent liver resection for a single CLM were reviewed. Of the 86 patients, 66 patients received chemotherapy and 20 patients did not receive chemotherapy before liver resection...

BACKGROUND: Although laparoscopic major hepatectomy (LMH) is becoming increasingly common in specialized centers, data regarding laparoscopic extended major hepatectomies (LEMH) and their outcomes are limited. The aim of this study was to compare the perioperative characteristics and postoperative outcomes of LEMH to standard LMH. METHODS: All patients who underwent purely laparoscopic anatomical right or left hepatectomy and right or left trisectionectomy between February 1998 and January 2016 are enrolled...

Background: While brain metastases (BM) are the most common causes of neurologic disorders in patients with known systemic malignancies, they can often be the initial manifestations of an undetected primary elsewhere. BM are major causes of morbidity and mortality in cancer patients. Aims: We describe a mixed population (data from both retrospective and prospective collection) having a BM from a solid tumor. We report the percentage distribution of the most frequent types of BM, confirming the data published in the literature...

PURPOSE OF REVIEW: In this article, we focus on the potential benefits and risks of chemotherapy administration before (perioperative) or after (pseudoadjuvant) a curative resection of colorectal cancer (CRC) metastases. RECENT FINDINGS: In the published evidence, there is a lack of survival benefit from peri or postoperative chemotherapy in the context of resectable metastatic CRC. However, high-risk patients may have a certain benefit when receiving a postoperative cytotoxic treatment...

BACKGROUND: Adrenal incidentalomas (AIs) are regularly discovered on staging computed tomography (CT) of patients with colorectal cancer (CRC). Although CRC is considered unlikely to metastasize to the adrenal gland, it is not known how often an AI appears to be a CRC metastasis. This causes a diagnostic dilemma for many patients with newly diagnosed CRC. This study aimed primarily to describe the incidence of AIs and adrenal metastases in CRC patients. METHODS: A single-center cohort of 475 consecutive patients with newly diagnosed CRC was defined...

BACKGROUND: The major issue after liver resection for colorectal liver metastases (CRLM) is the high incidence of recurrence. Unlike open liver resection (OLR), recurrence following laparoscopic liver resection (LLR) is not well documented. The aim of this study was to analyze recurrence patterns and treatment following LLR for CRLM. STUDY DESIGN: All patients who underwent LLR for CRLM from 2000 to 2016 were reviewed. Patients who presented with recurrence were compared to those who did not...

Objective: Hepatitis B virus (HBV) infection has been shown to decrease the risk of liver metastasis in patients with non-metastatic colorectal cancer (CRC). However, the prognostic value of HBV infection in long-term survival of patients with colorectal liver-only metastases (CRLM) after liver resection has not yet been evaluated. This study aims to explore the association between HBV infection and survival in CRLM patients. Methods: A total of 289 CRLM patients undergoing liver resection were recruited at our center from September 1999 to August 2015...

Elevated levels of the carcinoembryonic antigen (CEA; CEACAM5) in the serum of colorectal cancer (CRC) patients represent a clinical biomarker that correlates with disease recurrence. However, a mechanistic role for soluble CEA (sCEA) in tumor progression and metastasis remains to be established. In this study, we report that sCEA acts as a paracrine factor, activating human fibroblasts by signalling through both the STAT3 and AKT1-mTORC1 pathways, promoting their transition to a cancer-associated fibroblast (CaF) phenotype...

Choosing the optimal treatment approach for patients with metastatic colorectal cancer (mCRC) demands that oncologists assess both clinical and genomic variables and individualize care based upon the findings. Clinically, choices depend on assessing the side of the colon in which the primary tumor originates, the sites and burden of metastatic disease, the patient's performance status, and their individual comorbidities. Genomic assessment of the tumor to discern the mutational status of genes such as RAS/RAF, HER2, and TRK, as well as assessing whether tumors have defective mismatch repair (dMMR) or high microsatellite instability (MSI-H), all factor in to potential treatment options and can determine clinical trial eligibility...

BACKGROUND: Diagnostic error in patients undergoing resection of colorectal liver metastases (CRLM) is unusual but exposes patients to unnecessary risks associated with treatment. The primary aim of this study was to determine the rate of and risk factors for a false-positive diagnosis of colorectal liver metastases in patients undergoing hepatic resection. The secondary aim was to develop and validate a risk score to predict a false-positive diagnosis. METHODS: Patients were identified from prospectively maintained databases...

Although the spread of extragenital tumors to individual female genital tract organs, particularly the ovary, has been much studied, histologic data with regard to secondary tumors involving the whole gynecologic tract are largely lacking. Thus, the aim of the study was to investigate the pathologic and clinical features of these tumors in order to better understand their features. This is a retrospective study of 196 secondary lesions involving the gynecologic tract. The parameters studied were the primary site, its histologic type and grade, the presence of mucous production, the type of secondary involvement, defined as distant metastasis, direct extension or locoregional recurrence, and the time to metastasis...

BACKGROUND The expression of aldehyde dehydrogenase 1A1 (ALDH1A1) is increased in several human tumors, including colorectal carcinoma (CRC). The aim of this study was to compare the expression ALDH1A1 in CRC tumor tissue compared with non-tumor adjacent tissue (NAT), using immunohistochemistry (IHC), and to determine whether the expression of the ALDH1A1 protein was associated with prognostic factors in CRC. MATERIAL AND METHODS Formalin-fixed paraffin-embedded (FFPE) tissue from 424 patients diagnosed with CRC, and 196 matched NATs were used to prepare tissue microarrays (TMAs)...
