    Abstract Background: Post-hepatectomy liver failure (PHLF) is one of the main causes of postoperative mortality and is challenging to predict early in patients after liver resection. Some studies suggest that the postoperative serum phosphorus might predict outcomes in these patients.
    Aim: To perform a systematic literature review on hypophosphatemia and evaluate it as a prognostic factor for PHLF and overall morbidity.
    Methods: This systematic review was performed according to preferred reporting items for systematic reviews and meta-analyses statement. A study protocol for the review was registered in the International Prospective Register of Systematic Reviews database. PubMed, Cochrane and Lippincott Williams & Wilkins databases were systematically searched up to March 31, 2022 for studies analyzing postoperative hypophosphatemia as a prognostic factor for PHLF, overall postoperative morbidity and liver regeneration. The quality assessment of the included cohort studies was performed according to the Newcastle-Ottawa Scale.
    Results: After final assessment, nine studies (eight retrospective and one prospective cohort study) with 1677 patients were included in the systematic review. All selected studies scored ≥ 6 points according to the Newcastle-Ottawa Scale. Cutoff values of hypophosphatemia varied from < 1 mg/dL to ≤ 2.5 mg/dL in selected studies with ≤ 2.5 mg/dL being the most used defining value. Five studies analyzed PHLF, while the remaining four analyzed overall complications as a main outcome associated with hypophosphatemia. Only two of the selected studies analyzed postoperative liver regeneration, with reported better postoperative liver regeneration in cases of postoperative hypophosphatemia. In three studies hypophosphatemia was associated with better postoperative outcomes, while six studies revealed hypophosphatemia as a predictive factor for worse patient outcomes.
    Conclusion: Changes of the postoperative serum phosphorus level might be useful for predicting outcomes after liver resection. However, routine measurement of perioperative serum phosphorus levels remains questionable and should be evaluated individually.

    Abstract Background: Dynamic contrast-enhanced magnetic resonance imaging is a noninvasive imaging modality that can supply information regarding the tumor anatomy and physiology. The aim of the study was to analyze DCE-MRI perfusion parameters in normal pancreatic parenchymal tissue and PDAC and to evaluate the efficacy of this diagnostic modality in determining the tumor grade.
    Methods: A single-center retrospective study was performed. A total of 28 patients with histologically proven PDAC underwent DCE-MRI; the control group enrolled 14 patients with normal pancreatic parenchymal tissue; the radiological findings were compared with histopathological data. The study patients were further grouped according to the differentiation grade (G value): well- and moderately differentiated and poorly differentiated PDAC.
    Results: The median values of K
    Conclusions: Ve and iAUC DCE-MRI perfusion parameters are important as independent diagnostic criteria predicting the probability of PDAC; the Ktrans and iAUC DCE-MRI perfusion parameters may serve as effective independent prognosticators preoperatively identifying poorly differentiated PDAC.

    Abstract Introduction: Various inflammatory markers have been investigated for a prognostic role in patients with resectable pancreatic cancer. However, the value of preoperative platelet to lymphocyte ratio (PLR) remains controversial. We performed a systematic review and meta-analysis of PLR as a preoperative prognostic factor for resectable pancreatic cancer.
    Material and methods: Systematic literature search was conducted for studies assessing PLR influence as a preoperative prognostic factor in resectable pancreatic cancer patients. Random-effects model was applied for pooling hazard ratios and 95% confidence intervals related to overall survival (OS) and disease-free survival (DFS).
    Results: Fourteen articles with 2,743 patients were included in the study. According to the analysis, high PLR had no correlation with decreased OS. Due to high heterogeneity among studies, subgroup analysis was performed. Better OS was associated with low PLR in Asian patients, patients with mixed type of operation performed, and patients with preoperative PLR ≤150. Low PLR was associated with significantly better DFS.
    Conclusions: PLR is a predictive factor of better DFS in patients with resectable pancreatic cancer. However, available evidence does not support PLR as a reliable prognostic factor for OS.

    Abstract Introduction: Tumor grade, one of the most important risk factors for survival, is routinely determined after examining the biopsy material or a surgically removed specimen. The aim of the study was to analyze computed tomography (CT) perfusion parameters and diffusion-weighted imaging apparent diffusion coefficient (ADC) values in pancreatic ductal adenocarcinoma (PDAC) and to establish the diagnostic value of these modalities determining the tumor grade.
    Materials and methods: A prospective clinical study included 56 subjects with PDAC. All the patients had a local perfusion assessment and ADC measurement of the tumor. For the prediction of poor tumor differentiation sensitivity, specificity, positive, and negative predictive values for each perfusion CT and ADC parameters based on cutoff values from ROC analysis were calculated.
    Results: Mean transit time (MTT) and ADC values were found to be independent prognosticators for the presence of G3 PDAC. MTT and ADC at the cutoff of 17.37 s and 1.15 × 10-3 mm2/s, respectively, appeared to be significant parameters discriminating against the differentiation grade of PDAC. If both values exceeded the defined cutoff point, the estimated probability for the presence of G3 PDAC was 89.29%.
    Conclusion: The MTT parameter, calculated with the deconvolution method, and the ADC value may serve as effective independent prognosticators identifying poorly differentiated PDAC.

    Abstract Hypermethylation of tumor suppressor genes and hypomethylation of oncogenes might be identified as possible biomarkers in gastric cancer (GC). We aimed to assess the DNA methylation status of selected genes in GC tissue samples and evaluate these genes' prognostic importance on patient survival. Patients (99) diagnosed with GC and who underwent gastrectomy were included. We selected a group of genes (RAD51B, GFRA3, AKR7A3, HOXA11, TUSC3, FLI1, SEZ6L, GLDC, NDRG) which may be considered as potential tumor suppressor genes and oncogenes. Methylation of the HOXA11 gene promoter was significantly more frequent in GC tumor tissue (

    Abstract Background and objective: This study deals with an important issue of setting the role and value of the dynamic computed tomography (CT) perfusion analysis in diagnosing pancreatic ductal adenocarcinoma (PDAC). The study aimed to assess the efficacy of perfusion CT in identifying PDAC, even isodense or hardly depicted in conventional multidetector computed tomography.
    Methods: A total of 56 patients with PDAC and 56 control group patients were evaluated in this study. A local perfusion assessment, involving the main perfusion parameters, was evaluated for all the patients. Sensitivity, specificity, positive, and negative predictive values for each perfusion CT parameter were defined using cutoff values calculated using receiver operating characteristic curve analysis. We accomplished logistic regression to identify the probability of PDAC.
    Results: Blood flow (BF) and blood volume (BV) values were significant independent diagnostic criteria for the presence of PDAC. If both values exceed the determined cutoff point, the estimated probability for the presence of PDAC was 97.69%.
    Conclusions: Basic CT perfusion parameters are valuable in providing the radiological diagnosis of PDAC. The estimated BF and BV parameters may serve as independent diagnostic criteria predicting the probability of PDAC.

    Abstract Ampulla of Vater metastases from renal cell carcinoma are rare. The time between detection of the primary tumour and its metastasis may extend to years. Management should be aggressive, since the prognosis of renal cell carcinoma is unpredictable and curative surgery of metastases may extend patient survival and even lead to definite cure. Herein we report a case of long-term survival after successful surgical treatment of a renal cell carcinoma metastasis to the ampulla of Vater. A 62-year-old man with a history of renal cell carcinoma in the left kidney underwent a successful left nephrectomy. Eight months later duodenoscopy showed a tumour at the site of papilla of Vater. Biopsy confirmed the diagnosis of carcinoma. Contrast enhanced computer tomography scan verified the periampullary mass, dilatation of the pancreatic and the common bile duct. No radiological signs of either local advancement or distant metastases were present. Pylorus-preserving pancreatoduodenectomy with lymphadenectomy was performed. Pathology report disclosed metastatic lesions in the papilla of Vater from the clear cell carcinoma of the kidney. The postoperative course was uneventful, and the patient lived for 14 years after pancreatoduodenectomy and, following thorough investigations, was free from local and systemic recurrence. Pancreatoduodenectomy can provide long-term survival in selected cases with solitary papilla of Vater metastasis from renal cell carcinoma. Favourable long-term survival rates suggest that these patients should be considered candidates for pancreatoduodenectomy if experienced pancreatic surgeon is available and no other metastases are found.

    Abstract : The risk for postoperative venous thromboembolism (VTE) is increased in patients aged more than 70 years and in elderly patients presenting with co-morbidities, for example cardiovascular disorders, malignancy or renal insufficiency. Therefore, risk stratification, correction of modifiable risks and sustained perioperative thromboprophylaxis are essential in this patient population. Timing and dosing of pharmacoprophylaxis may be adopted from the non-aged population. Direct oral anti-coagulants are effective and well tolerated in the elderly; statins may not replace pharmacological thromboprophylaxis. Early mobilisation and use of non-pharmacological means of thromboprophylaxis should be exploited. In elderly patients, we suggest identification of co-morbidities increasing the risk for VTE (e.g. congestive heart failure, pulmonary circulation disorder, renal failure, lymphoma, metastatic cancer, obesity, arthritis, post-menopausal oestrogen therapy) and correction if present (e.g. anaemia, coagulopathy) (Grade 2C). We suggest against bilateral knee replacement in elderly and frail patients (Grade 2C). We suggest timing and dosing of pharmacological VTE prophylaxis as in the non-aged population (Grade 2C). In elderly patients with renal failure, low-dose unfractionated heparin (UFH) may be used or weight-adjusted dosing of low molecular weight heparin (Grade 2C). In the elderly, we recommend careful prescription of postoperative VTE prophylaxis and early postoperative mobilisation (Grade 1C). We recommend multi-faceted interventions for VTE prophylaxis in elderly and frail patients, including pneumatic compression devices, low molecular weight heparin (and/or direct oral anti-coagulants after knee or hip replacement) (Grade 1C). : This article is part of the European guidelines on perioperative venous thromboembolism prophylaxis.
