The Prognostic Value of Renal Function in Acute Pulmonary Embolism—A Multi-Centre Cohort Study

2018

Background Haemodynamic alterations caused by acute pulmonary embolism (PE) may affect multi-organ function including kidneys. This multi-centre, multinational cohort study aimed to validate the prognostic significance of estimated glomerular filtration rate (eGFR) and its potential additive value to the current PE risk assessment algorithms. Methods The post hoc analysis of pooled prospective cohort studies: 2,845 consecutive patients (1,424 M/1,421 F, 66 ± 17 years) with confirmed acute PE and followed up for 180 days. We tested prognostic value of pre-specified eGFR level ≤60 mL/min/1.73 m2 calculated on admission according to the Modification of Diet in Renal Disease study equation. Th…

Association between antithrombotic treatment and outcomes at 1-year follow-up in patients with atrial fibrillation: the EORP-AF General Long-Term Reg…

2019

Aims In recent years, stroke prevention in patients with atrial fibrillation (AF) has radically changed, with increasing use of non-vitamin K antagonist oral anticoagulants (NOACs). Contemporary European data on AF thromboprophylaxis are needed. Methods and results We report 1-year follow-up data from the EURObservational Research Programme in Atrial Fibrillation (EORP-AF) General Long-Term Registry. Outcomes were assessed according to antithrombotic therapy. At 1-year follow-up, 9663 (88.0%) patients had available data for analysis: 586 (6.1%) were not treated with any antithrombotic; 681 (7.0%) with antiplatelets only; 4066 (42.1%) with vitamin K antagonist (VKA) only; 3167 (32.8%) with …

Overexpression of p63 is associated with radiation resistance and prognosis in oral squamous cell carcinoma

2010

Summary Background : The tumor suppressor homologue p63 is expressed in basal and parabasal layers of intraoral mucosa. Full length transcripts with transactivational domain (TA forms) present with homology to p53 and implicate functions governing cell proliferation, differentiation and apoptosis control. To date studies show an increase of p63 expression in oral dysplasia and additionally high expression levels correlated with poor prognosis for patients with OSCC, whereas a possible link to radiation resistance of tumors has not been investigated yet. In the present study we tested the hypothesis for p63 being a marker of radioresistance and overall survival in OSCC. Methods : p63 Express…

Comparison of prognostic models in patients with advanced Hodgkin disease

2001

Several prognostic systems have been elaborated for patients with Hodgkin disease (HD) over the last 12 years, but early identification of a reasonably large group of both low and high risk, advanced stage patients remains unsatisfactory.Seven well known models were applied to 516 patients with advanced HD, with 315 patients used for the study sample and 201 patients used for the test sample. Individual performances as well as joint performances were analyzed univariately and multivariately in relation to overall survival, recurrence free survival, and time to treatment failure by means of a proportional hazards model.None of the models identified a group containing10% of patients from the …

Impact of relative dose intensity of oxaliplatin in adjuvant therapy among stage III colon cancer patients on early recurrence: a retrospective cohor…

2020

Abstract Background Oxaliplatin-based therapy with FOLFOX-4 or CAPOX administered over 6 months remains the standard adjuvant treatment for stage III colon cancer (CC) patients. However, many patients experience dose reduction or early termination of chemotherapy due to oxaliplatin toxicity, which may increase the risk of early recurrence. The objective of this study was to analyze the relationship between the relative dose intensity of oxaliplatin (RDI-O) and early recurrence among stage III CC patients. Methods The study included 365 patients treated at five oncology centers in Poland between 2000 and 2014. Survival analysis was performed using the Kaplan-Meier method. Univariate analysis…

Prognostic value of histopathologic parameters of esophageal squamous cell carcinoma.

1995

Background. The grading of squamous cell carcinoma (SCC) of the esophagus as proposed by the World Health Organization (WHO) has not yet proved to be prognostically significant. Therefore, the prognostic impact of various histologic parameters was investigated and compared with that of the WHO grading. Methods. Hematoxylin and eosin-stained tumor samples from 138 patients with SCC of the esophagus who underwent potentially curative resection (no residual tumor or distant metastases) were evaluated for the following histologic parameters: degree of keratinization, nuclear polymorphism, pattern of invasion, mitotic activity, and inflammatory response. The prognostic impact of these parameters…

Efficacy of ultrasound B-scan compared with physical examination in follow-up of melanoma patients

2001

BACKGROUND The value of ultrasound B-scan for routine follow-up of melanoma patients still is not generally accepted. Therefore, the authors compared the efficacy of physical examination (PE) with ultrasound B-scan (UBS) for detection of regional tumor recurrence in melanoma patients. The aim of the current study was to evaluate whether early detection of metastases improves relapse-free and overall survival. METHODS For a period of 4 years, 829 consecutive melanoma patients were followed prospectively. Physical examination of 3011 patients and concomitant UBS of in-transit routes and regional lymph node basins were performed. Suspicious lesions were diagnosed by fine-needle aspiration cyto…

Association Between Individual and Combined SNPs in Genes Related to Innate Immunity and Incidence of CMV Infection in Seropositive Kidney Transplant…

2014

In this study, we assessed the association between single-nucleotide polymorphisms (SNPs) in seven candidate genes involved in orchestrating the immune response against cytomegalovirus (CMV) and the 12-month incidence of CMV infection in 315 CMV-seropositive kidney transplant (KT) recipients. Patients were managed either by antiviral prophylaxis or preemptive therapy. CMV infection occurred in 140 patients (44.4%), including 13 episodes of disease. After adjusting for various clinical covariates, patients harboring T-allele genotypes of interleukin-28B (IL28B) (rs12979860) SNP had lower incidence of CMV infection (adjusted hazard ratio [aHR]: 0.66; 95% confidence interval [CI]: 0.46-0.96; p…

Bcl-2 as prognostic factor in head and neck squamous cell carcinoma

2005

A series of 66 cases of oral squamous cell carcinoma (OSCC) was retrospectively analyzed by immunohisto-chemistry for bcl-2 expression to verify its predictive value for clinical outcome in patients with OSCC. After grouping for bcl-2 expression, OSCCs were statistically analyzed for the variables age, gender, histological grading (G), TNM, staging, recurrence, and overall survival rate. Univariate and multivariate (Cox regression) analyses were performed. Thirty-six OSCC (54.5%) showed expression for bcl-2, whereas 30 (44.5%) were negative. No statistical association was found between bcl-2 expression and any variables considered at baseline. Overall disease-specific survival rate at 72 mo…

A New Clinical and Immunovirological Score for Predicting the Risk of Late Severe Infection in Solid Organ Transplant Recipients: The CLIV Score

2020

Abstract Background We aimed at constructing a composite score based on Epstein-Barr virus DNAemia (EBVd) and simple clinical and immunological parameters to predict late severe infection (LI) beyond month 6 in solid organ transplantation (SOT) recipients. Methods Kidney and liver transplant recipients between May 2014 and August 2016 at 4 participating centers were included. Serum immunoglobulins and complement factors, peripheral blood lymphocyte subpopulations, and whole blood EBVd were determined at months 1, 3, and 6. Cox regression analyses were performed to generate a weighted score for the prediction of LI. Results Overall, 309 SOT recipients were followed-up for a median of 1000 da…
