Background: The incidence of colorectal cancer (CRC) in patients who are less than 50 years old (early-onset colorectal cancer, EO-CRC) has risen markedly around the world in recent decades. Because of a lack of early detection programs for young patients, EO-CRC is often not detected until it has reached an advanced stage. In this study, we compared surgical patients with EO-CRC to those with so-called average-onset CRC (> 50 years; AO-CRC) using data from a large patient collective.

Methods: The 5-year post-trial follow-up (FU) data were obtained in an observational manner at a 3- and a 5-year visit only for those Harmony patients who consented to participate and covered clinical events that occurred from the second year onwards.
Results: Biopsy-proven acute rejection and death-censored graft loss rates remained low and independent of RSWD.
The prevalence and adequacy of diagnostic approaches for temporomandibular disorders (TMD) in children and adolescents are still matters of debate. This study aimed to determine the prevalence of TMD and oral habits in children and adolescents aged 7-14 years and evaluate the consistency between self-reported TMD symptoms and clinical findings using a shortened Axis I of Diagnostic Criteria for TMD (DC/TMD). Children (aged 7-10) and adolescents (aged 11-14) of both sexes were invited to participate in this study ( = 1468).

We conducted a randomised clinical trial to investigate RHT with cisplatin added to gemcitabine (GPH) compared with gemcitabine (G) in the adjuvant setting of resected pancreatic ductal adenocarcinoma.
Methods: This randomised, multicentre, open-label trial randomly assigned patients to either GPH (gemcitabine 1000 mg/m on day 1, 15 and cisplatin 25 mg/m with RHT on day 2, 3 and 15,16) or to G (gemcitabine 1000 mg/m on day 1,8,15), four-weekly over six cycles.
The mechanical properties of cured wood adhesive films were tested in a dry state by means of nanoindentation. These studies have found that the application of adhesives have an effect on the accuracy of the hardness and elastic modulus determination. The highest values of hardness among the tested adhesives at 20 °C have condensation resins: MF (0.

Untargeted cfDNA analysis using whole-genome sequencing (WGS) does not need a priori knowledge of the patient´s mutation profile.
Methods: Here we established LIquid biopsy Fragmentation, Epigenetic signature and Copy Number Alteration analysis (LIFE-CNA) using WGS with ~ 6× coverage for detection of circulating tumor DNA (ctDNA) in CRC patients as a marker for CRC detection and monitoring.
Introduction: The chemokine fractalkine (CX3CL1) is critically involved in the pathophysiology of different inflammatory diseases and myocardial ischemia-reperfusion (I/R). This study aimed to analyze the role of CX3CL1 in the activation of platelets and leukocytes during hepatic I/R.
Methods: Under inhalation anesthesia, C57BL6 mice were subjected to warm hepatic I/R (90 min/240 min).
Circulating tumor DNA (ctDNA) is a promising liquid biopsy (LB) marker to support clinical decisions in precision medicine. For implementation into routine clinical practice, clinicians need precise ctDNA level cutoffs for reporting residual disease and monitoring tumor burden changes during therapy. We clinically validated the limit of blank (LOB) and the limit of quantification (LOQ) of assays for the clinically most relevant somatic variants p.

Methods: We included 45 patients with known HCC who underwent contrast-enhanced MRI of the liver prior to liver transplantation or tumor resection. Tumor size was assessed pathologically for all patients.
Background: Analysis of circulating tumor DNA (ctDNA) in plasma is a powerful approach to guide decisions in personalized cancer treatment. Given the low concentration of ctDNA in plasma, highly sensitive methods are required to reliably identify clinically relevant variants.
Methods: We evaluated the suitability of 5 droplet digital PCR (ddPCR) assays targeting KRAS, BRAF, and EGFR variants for ctDNA analysis in clinical use.
Pedicle clamping (PC) during liver resection for colorectal metastases (CRLM) is used to reduce blood loss and allogeneic blood transfusion (ABT). The effect on long-term oncologic outcomes is still under debate. A retrospective analysis of the impact of PC on ABT-demand regarding overall (OS) and recurrence-free survival (RFS) in 336 patients undergoing curative resection for CRLM was carried out.

To do so, a set of 21 doping agents, spiked in urine and analyzed after dilute and shoot treatment, was used to assess the variability of their retention times between four different laboratories, all equipped with the same chromatographic system and with the same ultra-high performance supercritical fluid chromatography stationary phase chemistry. The average relative standard deviations (RSD%) demonstrated a good reproducibility of the retention times for 19 out of 21 analytes, with RSD% values below 3.

Summary And Background Data: Patients receiving LT) for HCC are at a high risk for tumor recurrence. Calcineurin inhibitors have shown evidence to promote cancer growth, whereas mammalian target of rapamycin (mTOR) inhibitors like sirolimus have anticancer effects.
Background: Symptomatic rectal stump leakage (RSL) is a serious complication after discontinuity resection and requires immediate surgical, interventional, or endoscopic therapy. Re-operations are associated with high morbidity and mortality in these mostly very ill patients. Endoscopic vacuum therapy (EVT) has been established for management of anastomotic leakage; however, its effectiveness for RSL treatment has not been analyzed in detail yet.

Methods: Conversion to resectability was defined as conversion of initially unresectable to resectable disease at best response as determined by retrospective assessment. Univariate and multivariate logistic models were fitted with resectability at best response as response variable.
Purpose: To observe the technical and clinical outcome as well as safety of CT fluoroscopy-guided drain placement in the multimodal clinical complication management of superinfected gastric leakage after sleeve gastrectomy.
Materials And Methods: All consecutive patients who underwent CT fluoroscopy-guided drain placement to treat superinfected postoperative leakage after sleeve gastrectomy in our department between 2007 and 2014 were included in this retrospective study. All interventions were performed on a 16- or 128-row CT scanner under intermittent CT fluoroscopy guidance (15-25 mAs, 120 kV).
Background: Earlier detection of anastomotic leakage (AL) after colorectal procedures could minimize the detrimental clinical impact of AL and thereby reduce morbidity and mortality.
Study Design: We conducted a prospective study with assessment of the diagnostic accuracy of monocytic HLA-DR (mHLA-DR) expression compared with WBCs, C-reactive protein (CRP), and procalcitonin (PCT) in predicting AL in patients undergoing elective colorectal operation with anastomosis.
Results: Comparison of the blood marker values on postoperative day (POD) 4 revealed significant differences for all markers, but the difference for mHLA-DR was highly significant (15% expression of monocytes in AL patients vs 34% in patients without AL; p = 0.
Background: A defunctioning stoma can become necessary in a relevant number of patients undergoing gastrointestinal surgery. As a matter of course, patients seek an early closure of the stoma. However, preoperative management of these patients varies and the prediction of continence after stoma removal can become challenging.

In this pilot animal study we examined whether it is possible to visualize the embryonal resection layers by using intraarterial indocyanine green (ICG) staining when performing total mesorectal excision (TME) for carcinoma of the rectum. e injected ICG into the inferior mesenteric artery (AMI) of four swines to see whether the watershed area of the arterial supply zone can be sufficiently visualized by fluorescence imaging in order to mark the right dissection area along the fascia parietalis before and during resection. We observed a fluorescence signal in all the supplied areas of AMI but not in other parts of the abdominal cavity or other organs.

However, it is not clear whether desmoplastic reaction is associated with tumor-specific characteristics and diminished prognosis. Therefore, the aim of this study was to investigate whether the presence of a desmoplastic reaction correlates with prognostic and molecular markers of neuroendocrine tumors of the small intestine.
