The 3-60 criteria challenge established predictors of postoperative mortality and enable timely therapeutic intervention after liver resection.

ABSTRACT: Background:To date, definitions of liver dysfunction (LD) after hepatic resection rely on late postoperative time points. Further, the used parameters are markedly influenced by perioperative management. Thus, we aimed to establish a very early postoperative score to predict postoperative mortality. Methods:Liver related parameters were evaluated after liver resection in a retrospective evaluation cohort of 228 colorectal cancer patients with liver metastasis (mCRC) and subsequent validation in a prospective set of 482 consecutive patients from 4 independent institutions undergoing hepatic resection was performed. Results:C-reactive protein (CRP, AUC =0.739, P<0.001) and antithrombinIII-activity (ATIII, AUC =0.844, P<0.001) on the first postoperative day (POD) were found to be elevated in patients with LD. Cut-off values for CRP at 3 mg/dL and for ATIII at 60% significantly identified high-risk patients for postoperative LD and mortality (P<0.001) and thus defined the 3-60 criteria on POD1. The 3-60 criteria showed superior sensitivity and specificity compared to established criteria for LD [3-60 criteria: total positive patients: 26 patients (70% mortality detected), odds ratio (OR): 48.8; International Study Group for Liver Surgery: total positive patients: 43 (70% mortality detected), OR: 23.3; Peak7: total positive patients: 9 (30% mortality detected), OR: 27.8; 50-50: total positive patients: 9 (30% mortality detected), OR: 27.8]. These results could be validated in a multi-center analysis and ultimately the 3-60 criteria remained an independent predictor of postoperative mortality upon multivariable analysis. Conclusions:The 3-60 criteria on POD1 predict postoperative LD and mortality early after liver resection with a comparable or better accuracy than established criteria, allowing for immediate identification of high-risk patients.

Project description:Introduction. Increased plasma cell-free DNA (cfDNA) has been reported for various diseases in which cell death and tissue/organ damage contribute to pathogenesis, including sepsis. Gap Statement. While several studies report a rise in plasma cfDNA in bacteraemia and sepsis, the main source of cfDNA has not been identified. Aim. In this study, we wanted to determine which of nuclear, mitochondrial or bacterial cfDNA is the major contributor to raised plasma cfDNA in hospital subjects with bloodstream infections and could therefore serve as a predictor of bacteraemic disease severity. Methodology. The total plasma concentration of double-stranded cfDNA was determined using a fluorometric assay. The presence of bacterial DNA was identified by PCR and DNA sequencing. The copy numbers of human genes, nuclear β globin and mitochondrial MTATP8, were determined by droplet digital PCR. The presence, size and concentration of apoptotic DNA from human cells were established using lab-on-a-chip technology. Results. We observed a significant difference in total plasma cfDNA from a median of 75 ng ml-1 in hospitalised subjects without bacteraemia to a median of 370 ng ml-1 (P=0.0003) in bacteraemic subjects. The copy numbers of nuclear DNA in bacteraemic also differed between a median of 1.6 copies µl-1 and 7.3 copies µl-1 (P=0.0004), respectively. In contrast, increased mitochondrial cfDNA was not specific for bacteraemic subjects, as shown by median values of 58 copies µl-1 in bacteraemic subjects, 55 copies µl-1 in other hospitalised subjects and 5.4 copies µl-1 in healthy controls. Apoptotic nucleosomal cfDNA was detected only in a subpopulation of bacteraemic subjects with documented comorbidities, consistent with elevated plasma C-reactive protein (CRP) levels in these subjects. No bacterial cfDNA was reliably detected by PCR in plasma of bacteraemic subjects over the course of infection with several bacterial pathogens. Conclusions. Our data revealed distinctive plasma cfDNA signatures in different groups of hospital subjects. The total cfDNA was significantly increased in hospital subjects with laboratory-confirmed bloodstream infections comprising nuclear and apoptotic, but not mitochondrial or bacterial cfDNAs. The apoptotic cfDNA, potentially derived from blood cells, predicted established bacteraemia. These findings deserve further investigation in different hospital settings, where cfDNA measurement could provide simple and quantifiable parameters for monitoring a disease progression.

Project description:ObjectivesCurrent guidelines base the management of intraductal papillary mucinous neoplasms (IPMN) on several well-established resection criteria (RC), including cyst size. However, malignancy may occur in small cysts. Since branch-duct (BD) IPMN are not perfect spheres, volumetric and morphologic analysis might better correlate with mucin production and grade of dysplasia. Nonetheless, their role in malignancy (high-grade dysplasia/invasive cancer) prediction has been poorly investigated. Previous studies evaluating RC also included patients with solid-mass-forming pancreatic cancer (PC), which may affect the RC yield. This study aimed to assess the role of volume, morphology, and other well-established RC in malignancy prediction in patients with BD- and mixed-type IPMN after excluding solid masses.MethodsRetrospective ethical review-board-approved study of 106 patients (2008-2019) with histopathological diagnosis of BD- and mixed-type IPMN (without solid masses) and preoperative MRI available. Standard imaging and clinical features were collected, and the novel imaging features cyst-volume and elongation value [EV = 1 - (width/length)] calculated on T2-weighted images. Logistic regression analysis was performed. Statistical significance set at two-tails, p < 0.05.ResultsNeither volume (odds ratio (OR) = 1.01, 95% CI: 0.99-1.02, p = 0.12) nor EV (OR = 0.38, 95% CI: 0.02-5.93, p = 0.49) was associated with malignancy. Contrast-enhancing mural nodules (MN), main pancreatic duct (MPD) ≥ 5 mm, and elevated carbohydrate antigen (CA) 19-9 serum levels (> 37 μmol/L) were associated with malignancy (MN OR: 4.32, 95% CI: 1.18-15.76, p = 0.02; MPD ≥ 5 mm OR: 4.2, 95% CI: 1.34-13.1, p = 0.01; CA19-9 OR: 6.72; 95% CI: 1.89 - 23.89, p = 0.003).ConclusionsVolume and elongation value cannot predict malignancy in BD- and/or mixed-type IPMN. Mural nodules, MPD ≥ 5 mm and elevated CA19-9 serum levels are associated with higher malignancy risk even after the exclusion of solid masses.Key points• Novel and well-established resection criteria for IPMN have been evaluated after excluding solid masses. • BD-IPMN volume and elongation value cannot predict malignancy. • Main pancreatic duct ≥ 5 mm, mural nodules, and elevated carbohydrate antigen 19-9 levels are associated with malignancy.
