Exposure to UV radiation and risk of Hodgkin lymphoma: a pooled analysis.
Blood
PUBLISHED: 09-09-2013

Hide Abstract
Ultraviolet radiation (UVR) exposure has been inversely associated with Hodgkin lymphoma (HL) risk, but only inconsistently, only in a few studies, and without attention to HL heterogeneity. We conducted a pooled analysis of HL risk focusing on type and timing of UVR exposure and on disease subtypes by age, histology, and tumor-cell Epstein-Barr virus (EBV) status. Four case-control studies contributed 1320 HL cases and 6381 controls. We estimated lifetime, adulthood, and childhood UVR exposure and history of sunburn and sunlamp use. We used 2-stage estimation with mixed-effects models and weighted pooled effect estimates by inverse marginal variances. We observed statistically significant inverse associations with HL risk for UVR exposures during childhood and adulthood, sunburn history, and sunlamp use, but we found no significant dose-response relationships. Risks were significant only for EBV-positive HL (pooled odds ratio, 0.56; 95% confidence interval, 0.35 to 0.91 for the highest overall UVR exposure category), with a significant linear trend for overall exposure (P = .03). Pooled relative risk estimates were not heterogeneous across studies. Increased UVR exposure may protect against HL, particularly EBV-positive HL. Plausible mechanisms involving UVR induction of regulatory T cells or the cellular DNA damage response suggest opportunities for new prevention targets.

Predictors of histology, tissue eosinophilia and mast cell infiltration in Hodgkins lymphoma--a population-based study.
Eur. J. Haematol.
PUBLISHED: 07-26-2011
Show Abstract
Hide Abstract
Classical Hodgkins lymphoma (HL) lesions comprise few tumour cells, surrounded by numerous inflammatory cells. Like in other malignancies, the microenvironment is presumed to be clinically important in HL; however, microenvironment predictors remain poorly characterised. The aim of this study was to investigate how selected patient characteristics and genetic factors affect HL phenotype, in particular tissue eosinophilia, mast cell counts and HL histological subtype.

Effect of eosinophil cationic protein (ECP) on Hodgkin lymphoma cell lines.
Exp. Hematol.
PUBLISHED: 05-11-2011
Show Abstract
Hide Abstract
In Hodgkin lymphoma (HL), tumor eosinophilia indicates poor prognosis, probably caused by eosinophil-induced stimulation of tumor cells. Our aim was to investigate the effects of eosinophil cationic protein (ECP) on HL tumor cells in vitro.

Tissue microarray and digital image analysis: a methodological study with special reference to the microenvironment in Hodgkin lymphoma.
Histopathology
Show Abstract
Hide Abstract
Cancer research has moved from solely investigating the tumour cells to also including analysis of the tumour microenvironment; however, the methods utilized have not been evaluated for this change. The aim of this study was to compare tissue microarrays (TMA) to whole tissue sections (WS) with regard to cells in the tumour microenvironment. Manual evaluation and digital image analyses (DIA) were utilized and also compared.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
