Long-term follow-up of hepatitis C virus-positive patients with persistently normal serum transaminases
2013
Material and methods. This study prospectively evaluated the progression of liver disease in a group of anti-HCV-positive patients with persistently normal ALT levels (PNALT) who were HCV-RNA positive. Patients selected for this study were those who presented with PNALT according to the Italian Association for the Study of the Liver (AISF) criteria in the year 1995/96 and underwent liver biopsy. They were divided into two groups according to their ALT evolution. Forty-five patients were included in this study. Results. After a median follow-up time of 180 months twenty-five of them maintained PNALT, but two of these developed liver cirrhosis (LC) in a mean time of 174 and 202 months, respec…
Anaplastic large cell lymphoma (CD30+/Ki-1+). Analysis of 35 cases followed at GISL centres
1995
Between January 1988 and June 1992, 35 patients with primary anaplastic large cell lymphoma (ALCL)CD30+ were referred to one of the institutions participating in GISL (Gruppo Italiano per lo Studio dei Linformi). 16 patients were treated with ProMACE-CytaBOM, two with MACOP-B, one with CHOP and one with LSA2-L2. As of November 1990, all newly diagnosed patients were treated with MOPP/EBV/CAD hybrid. 27 (77%) cases of ALCL CD30+ and 8 (23%) cases of Hodgkin's-related (HR) lymphoma CD30+ were diagnosed. Extranodal disease was present in 22 cases (63%), and 8 patients (23%) had primary bone marrow involvement. Twenty-three complete remissions (CR) (66%), six partial remissions (PR) (17%) and s…
BRCA1/BRCA2 rearrangements and CHEK2 common mutations are infrequent in Italian male breast cancer cases
2008
Male breast cancer (MBC) is a rare and poorly known disease. Germ-line mutations of BRCA2 and, to lesser extent, BRCA1 genes are the highest risk factors associated with MBC. Interestingly, BRCA2 germ-line rearrangements have been described in high-risk breast/ovarian cancer families which included at least one MBC case. Germ-line mutations of CHEK2 gene have been also implicated in inherited MBC predisposition. The CHEK2 1100delC mutation has been shown to increase the risk of breast cancer in men lacking BRCA1/BRCA2 mutations. Intriguingly, two other CHEK2 mutations (IVS2+1G>A and I157T) and a CHEK2 large genomic deletion (del9-10) have been associated with an elevated risk for prostate c…
Non-Hodgkin lymphoma and obesity: A pooled analysis from the InterLymph consortium
2008
Nutritional status is known to alter immune function, a suspected risk factor for non-Hodgkin lymphoma (NHL). To investigate whether long-term over, or under, nutrition is associated with NHL, self-reported anthropometric data on weight and height from over 10,000 cases of NHL and 16,000 controls were pooled across 18 case-control studies identified through the International Lymphoma Epidemiology Consortium. Study-specific odds ratios (OR) were estimated using logistic regression and combined using a random-effects model. Severe obesity, defined as BMI of 40 kg m-2 or more, was not associated with NHL overall (pooled OR = 1.00, 95% confidence interval (CI) 0.70-1.41) or the majority of NHL …
Phase I/II study of pixantrone in combination with cyclophosphamide, vincristine, and prednisone in patients with relapsed aggressive non-Hodgkin lym…
2011
Pixantrone is a potentially more effective, less cardiotoxic alternative to doxorubicin for patients with aggressive non-Hodgkin lymphoma (aNHL). This phase I/II non-comparative study evaluated pixantrone in place of doxorubicin in the standard CHOP regimen (cyclophosphamide, doxorubicin, vincristine, and prednisone), i.e. CPOP (cyclophosphamide, pixantrone, vincristine, and prednisone), in patients with relapsed aNHL who had previously received CHOP ± rituximab. Patients were administered pixantrone on day 1 of each 21-day cycle. Phase I (n = 35) dose escalation from 80 mg/m(2) to 180 mg/m(2) established the phase II (n = 30) dose as 150 mg/m(2). In phase II, 20 patients (67%) received all…
HIV-related non-Hodgkin lymphomas affecting the oral cavity: a clinicopathologic study of 11 cases
2021
HIV-related non-Hodgkin lymphomas of the oral cavity are rare lesions with aggressive clinical behaviour. The aim of this study is to describe the clinicopathological features of a series of HIV-related oral non-Hodgkin lymphomas. Eleven cases of oral lymphomas affecting HIV-positive patients were retrieved from 2012 to 2019. Clinicopathological features regarding age, sex, tumour location, clinical presentation, laboratory findings, disease stage and follow-up were obtained. Histologic, immunohistochemical and in situ hybridization for EBV detection were done for diagnosis confirmation. Overall survival was estimated by Kaplan?Meier curve. Males predominated, with a mean age of 40.3 years-…
Large-scale association analysis identifies 13 new susceptibility loci for coronary artery disease
2011
1. The CARDIoGRAM Consortium. Large-scale association analysis identifies 13 new susceptibility loci for coronary artery disease. Nature Genetics. 2011;43:333–338. ### Study Hypothesis Recently, genome-wide association studies (GWAS) have identified several common variants that are associated with risk of coronary artery disease (CAD) and myocardial infarction (MI). The authors state that the current loci discovered in CAD and MI GWAS explain only a small fraction of the heritability of this complex disease. The authors hypothesized that a larger study would provide more power to discover common variants with modest effect sizes. Therefore, they formed the Coronary ARtery DIsease Genome-wid…
Identification of epithelial gaps in human small and large intestine by confocal endomicroscopy.
2007
Background & Aims: Confocal endomicroscopy is an emerging technology that poses the endoscopist with challenges for identifying epithelial structures in the human intestine. We have shown previously that the murine intestinal epithelium is punctuated by gaps caused by cell shedding. The goals of this study were to determine if confocal endomicroscopy could resolve the presence of human epithelial gaps and whether a proinflammatory cytokine could increase cell shedding. Methods: Intestinal mucosa was imaged after staining with acriflavine. Confocal endomicroscopy of 17 patients yielded 6277 images from the human terminal ileum and rectum. Results were validated by parallel studies of anesthe…
ADC measurements in diffuse large B-cell lymphoma and follicular lymphoma: a DWI and cellularity study.
2012
Diffusion-weighted magnetic resonance imaging (DW-MRI) allows quantifying the random motion of water molecules in tissue by means of apparent diffusion coefficient (ADC) measurements. The aim of the study was to determine whether ADC measurements allow discrimination of diffuse large B-cell lymphoma (DLBCL) from follicular lymphoma (FL), and to examine the relationship between cellularity and ADC value of the tumor using DWI.Thirty-two patients with histologically proven non-Hodgkin lymphoma (21 with DLBCL and 11 with FL, 17 males and 15 females, mean age 62±13 years) underwent conventional MRI and DWI examination before treatment. The ADC values of DLBCL were compared to those of FL. The A…
MYD88 L265P mutation and interleukin‐10 detection in cerebrospinal fluid are highly specific discriminating markers in patients with primary central …
2021
Reliable biomarkers are needed to avoid diagnostic delay and its devastating effects in patients with primary central nervous system (CNS) lymphoma (PCNSL). We analysed the discriminating sensitivity and specificity of myeloid differentiation primary response (88) (MYD88) L265P mutation (mut-MYD88) and interleukin-10 (IL-10) in cerebrospinal fluid (CSF) of both patients with newly diagnosed (n = 36) and relapsed (n = 27) PCNSL and 162 controls (118 CNS disorders and 44 extra-CNS lymphomas). The concordance of MYD88 mutational status between tumour tissue and CSF sample and the source of ILs in PCNSL tissues were also investigated. Mut-MYD88 was assessed by TaqMan-based polymerase chain reac…
