Should we use nomograms for risk predictions in diffuse large B cell lymphoma patients? A systematic review.

Models based on risk stratification are increasingly reported for Diffuse large B cell lymphoma (DLBCL). Due to a rising interest in nomograms for cancer patients, we aimed to review and critically appraise prognostic models based on nomograms in DLBCL patients. A literature search in PubMed/Embase identified 59 articles that proposed prognostic models for DLBCL by combining parameters of interest (e.

Influence of Heat Stress on Body Temperatures Measured by Infrared Thermography, Blood Metabolic Parameters and Its Correlation in Sheep.

The aim of this research is to examine the influence of heat stress (HS) on body temperature (BT) measured rectally (RT) or by infrared thermography (IRT) of the nose (NT), eye (ET), leg (LT) and abdominal (AT) regions in intensively and extensively breed sheep and to detect a correlation between body temperature and metabolic response in sheep. A total of 33 Wurttemberg × Sjenica Pramenka sheep breeds were examined, 17 ewes were from outdoors and 16 were from indoor housing systems during three experimental periods (thermoneutral period, severe HS and moderate HS). Sheep under HS have a higher BT, and the magnitude of BT measured by infrared thermography (IRT) was higher than RT.

Relationships between Milk and Blood Biochemical Parameters and Metabolic Status in Dairy Cows during Lactation.

This study aimed to determine blood and milk metabolic parameters and their correlations for the purpose of evaluating metabolic status in dairy cows. Blood and milk samples were collected from 100 Holstein dairy cows during morning milking. The cows were allocated to four groups according to the production period, including cows in early ( = 18), full ( = 26), mid ( = 25) and late ( = 31) lactation.

Clinical Characteristics and Management of Patients With Concomitant Liver Cirrhosis and Lymphoma: A Systematic Review.

Over the years, a rising incidence of liver cirrhosis and lymphoma has been observed. Therefore, the risk of having cirrhosis as a comorbidity increases, thus challenging treatment approaches as data on the management of these patients is lacking. We performed a systematic review to summarize papers that analyzed patients with liver cirrhosis that occurred before and/or concomitantly to lymphoma.

The clinical applicability of current prognostic models in follicular lymphoma: A systematic review.

The Follicular Lymphoma International Prognostic Index (FLIPI) is widely used for risk stratification of patients with follicular lymphoma (FL). Motivated by evolvement in treatment modalities, several prognostic models for FL have been proposed recently. This systematic review aimed to identify available prognostic models for newly diagnosed FL and discuss their potential limitations.

Prognostic models in primary central nervous system lymphoma patients: A systematic review.

Over the last decade, several prognostic models have been proposed for primary central nervous system lymphoma (PCNSL), but consensus on the optimal model for these patients is absent or lacking. This study aims to review available prognostic models for PCNSL and discuss their prognostic features. A comprehensive literature search performed in Pubmed/Embase identified ten studies with a variable number of analysed patients (range 32-3453), which proposed 12 prognostic models.

25(OH) vitamin D deficiency in lymphoid malignancies, its prevalence and significance. Are we fully aware of it?

Introduction: Vitamin D has a role in cellular differentiation, proliferation, apoptosis, and angiogenesis and therefore is studied as a prognostic factor in cancer. The aim of our study was to assess the prevalence and significance of 25(OH)D deficiency in patients with lymphoid malignancies.

Methodology: Between January 2014 and June 2016 at the Clinic for Hematology, Clinical Center of Serbia, Belgrade, the pretreatment serum level of 25(OH)D was determined in 133 (62 women/71 men, median age 58 (18-84) years) previously untreated patients with lymphoid malignancy using a chemiluminescent immunoassay.

Is it possible to improve prognostic value of NCCN-IPI in patients with diffuse large B cell lymphoma? The prognostic significance of comorbidities.

The prognostic value of the International Prognostic Index (IPI) has been re-evaluated in the rituximab-treated diffuse large B cell lymphoma (DLBCL) patients. Accordingly, National Comprehensive Cancer Network-IPI (NCCN-IPI) has been introduced to estimate prognosis of DLBCL patients. However, comorbidities that frequently affect elderly DLBCL patients were not analyzed.

FCG (FLIPI, Charlson comorbidity index, and histological grade) score is superior to FLIPI in advanced follicular lymphoma.

The Follicular Lymphoma International Prognostic Index (FLIPI) is widely used in the identification of risk groups among follicular lymphoma (FL) patients. The aim of the present study was to evaluate the prognostic value of FLIPI combined with the Charlson comorbidity index (CCI) and histological grade of lymphoma. 224 newly diagnosed FL patients (median age 56 years) treated with immunochemotherapy were retrospectively analysed.

Development and validation of multivariable predictive model for thromboembolic events in lymphoma patients.

Lymphoma patients are at increased risk of thromboembolic events but thromboprophylaxis in these patients is largely underused. We sought to develop and validate a simple model, based on individual clinical and laboratory patient characteristics that would designate lymphoma patients at risk for thromboembolic event. The study population included 1,820 lymphoma patients who were treated in the Lymphoma Departments at the Clinics of Hematology, Clinical Center of Serbia and Clinical Center Kragujevac.

Gene Mutation Profiles in Primary Diffuse Large B Cell Lymphoma of Central Nervous System: Next Generation Sequencing Analyses.

The existence of a potential primary central nervous system lymphoma-specific genomic signature that differs from the systemic form of diffuse large B cell lymphoma (DLBCL) has been suggested, but is still controversial. We investigated 19 patients with primary DLBCL of central nervous system (DLBCL CNS) using the TruSeq Amplicon Cancer Panel (TSACP) for 48 cancer-related genes. Next generation sequencing (NGS) analyses have revealed that over 80% of potentially protein-changing mutations were located in eight genes (CTNNB1, PIK3CA, PTEN, ATM, KRAS, PTPN11, TP53 and JAK3), pointing to the potential role of these genes in lymphomagenesis.

OC-07 - Decoding risk for thromboembolic events in lymphoma patients.

Introduction: There are few prediction tools for estimating the risk of thrombosis but they are based on studies performed on hospitalized medical patients without cancer or on hospitalized neutropenic cancer patients without special consideration to lymphoma patients.

Aim: Aim of our study was to determine incidence of thromboembolic (TE) events in patients with non Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL) and chronic lymphocytic leukemia (CLL)/ small lymphocytic lymphoma (SLL) who were hospitalized to the lymphoma department in the Clinic of hematology, Clinical Center Serbia, Belgrade and Clinic of hematology, Clinical Center Kragujevac. Also, we assessed 2 predictive models (Padua and Khorana score) and create new model for the identification of lymphoma patients at risk for thromboembolism.

The Role of Lymphocyte to Monocyte Ratio, Microvessel Density and HiGH CD44 Tumor Cell Expression in Non Hodgkin Lymphomas.

Prognostic significance of immune microenvironment has been emphasized using the most advanced analysis, with consecutive attempts to reveal prognostic impact of this findings. The aim of this study was to compare and define prognostic significance of clinical parameters, microvessel density (MVD) in tumour tissue and expression of CD44s as adhesive molecule on tumour cells in diffuse large B cell lymphoma-DLBCL, primary central nervous system DLBCL-CNS DLBCL and follicular lymphoma-FL. A total of 202 histopathological samples (115 DLBCL/65 FL/22 CNS DLBCL) were evaluated.

Prognostic value of lymphocyte/monocyte ratio in advanced Hodgkin lymphoma: correlation with International Prognostic Score and tumor associated macrophages.

We studied the prognostic significance of the absolute lymphocyte/monocyte count ratio (ALC/AMC), its contribution to the prognostic value of the International Prognostic Score (IPS), and evaluated if ALC/AMC could serve as a proxy for the frequency of CD68 + tumor-associated macrophages (TAMs) in 101 patients with advanced Hodgkin lymphoma (HL). The receiver operating characteristic (ROC) curve identified best cut-off values of 2.0 for ALC/AMC and 25% for CD68 + TAM.

Serbian lymphoma study group: demografic characteristics of 257 patients with follicular lymphoma.

Background/aim: Follicular lymphoma (FL) is a B-cell tumor usually with indolent clinical course, yet in some cases the course of the disease can be very aggressive. The aim of the research was to determine distribution of patients into prognostic groups based on the International Prognostic Index (IPI) and Folicular Lymphoma International Prognostic Index (FLIPI) criteria, as well as to determine the importance of classifying patients into the prognostic groups, since this could potentially have the influence on selection of the treatment modality.

Methods: The retrospective study was performed on 257 patients with follicular lymphoma diagnosed between January 2000 and April 2011.

BCL2 positive and BCL6 negative diffuse large B cell lymphoma patients benefit from R-CHOP therapy irrespective of germinal and non germinal center B cell like subtypes.

Purpose: Despite major advances in the treatment of diffuse large B cell lymphoma (DLBCL), approximately one third of the patients progress or die, suggesting the existence of additional oncogenic events. The purpose of this study was to evaluate the prognostic value of the "Hans classifier", and BCL2 and MYC protein expression and gene alterations in DLBCL patients treated with CHOP or R-CHOP chemotherapy over a 5-year period. Furthermore, we tried to correlate these parameters with the International Prognostic Index (IPI).

Follicular lymphoma patients with a high FLIPI score and a high tumor burden: a risk stratification model.

Background/aim: The widely accepted Follicular Lymphoma International Prognostic Index (FLIPI) divides patients into three risk groups based on the score of adverse prognostic factors. The estimated 5-year survival in patients with a high FLIPI score is around 50%. The aim of this study was to analyse the prognostic value of clinical and laboratory parameters that are not included in the FLIPI and the New Prognostic Index for Follicular Lymphoma developed by the International Follicular Lymphoma Prognostic Factor Project (FLIPI2) indices, in follicular lymphoma (FL) patients with a high FLIPI score and high tumor burden.

Prognostic effect of comorbidity indices in elderly patients with multiple myeloma.

Background: Consideration of comorbidity, disability, and frailty represents a significant part of the treatment of elderly multiple myeloma (MM) patients. The aim of study was to analyze the effect of the Charlson Comorbidity Index (CCI) and scale of Instrumental Activities of Daily Living (IADL) on the course of disease.

Patients And Methods: The study included 110 newly diagnosed MM patients older than 65 years of age.

Multiple malignancies in a female patient with common variable immunodeficiency syndrome.

We herein present the case of a 55-year-old woman with a previous history of malignancies--uterine adenocarcinoma, basal cell carcinoma (which occurred twice consecutively), recurrent respiratory infections due to common variable immunodeficiency (CVID), and systemic granulomatous disease diagnosed at a later age. The patient suffered from diffuse large B cell lymphoma (DLBCL), which was successfully treated with R-CHOP chemotherapy, and continued with immunoglobulin supplementation. The patient was free of lymphoma and infectious complications for over 20 months despite her persistent immunodeficiency, but eventually developed colorectal adenocarcinoma.

Switching to BCL-6 Negativity in Relapsed Diffuse Large B Cell Lymphoma Correlated with More Aggressive Disease Course.

Diffuse large B-cell lymphoma (DLBCL) is the most frequent, complex and heterogeneous lymphoma of adulthood. Heterogeneity is expressed at clinical, genetic, and molecular levels. It is known that BCL-6 expression is a favorable prognostic factor in DLBCL.
