An evaluation of the polymorphisms Ins16bp and Arg72Pro in p53 as breast cancer risk modifiers in BRCA1 and BRCA2 mutation carriers
GC-HBOC - German Consortium for Hereditary Breast and Ovarian Cancer

Abstract (Expand)

The close functional relationship between p53 and the breast cancer susceptibility genes BRCA1 and BRCA2 has promoted the investigation of various polymorphisms in the p53 gene as possible risk modifiers … in BRCA1/2 mutation carriers. Specifically, two polymorphisms in p53, c.97-147ins16bp and p.Arg72Pro have been analysed as putative breast cancer susceptibility variants, and it has been recently reported that a p53 haplotype combining the absence of the 16-bp insertion and the presence of proline at codon 72 (No Ins-72Pro) was associated with an earlier age at the onset of the first primary tumour in BRCA2 mutation carriers in the Spanish population. In this study, we have evaluated this association in a series of 2932 BRCA1/2 mutation carriers from the Consortium of Investigators of Modifiers of BRCA1 and BRCA2.

Human Diseases: hereditary breast ovarian cancer syndrome

Structural aberrations affecting the MYC locus indicate a poor prognosis independent of clinical risk factors in diffuse large B-cell lymphomas treated within randomized trials of the German High-Grade Non-Hodgkin's Lymphoma Study Group (DSHNHL).
GLA - German Lymphoma Alliance

Abstract (Expand)

Recent retrospective studies of heterogeneously treated patients have suggested that chromosomal aberrations of the MYC gene locus indicate an unfavorable prognosis in diffuse large B-cell lymphoma … (DLBCL). Here, we investigated the prognostic impact of MYC aberrations analyzed by interphase fluorescence in situ hybridization in 177 patients with de novo DLBCL treated within the two prospective, randomized trials non-Hodgkin's lymphoma NHL-B1 and NHL-B2. MYC aberrations were detected in 14 DLBCL (7.9%). In a univariate analysis compared with MYC-negative DLBCL, MYC-positive cases showed a significantly shorter overall survival (OS) (P=0.047) and relevantly, though not significantly, shorter event-free survival (EFS) (P=0.062). In a Cox model adjusted for the international prognostic index, the presence of a MYC gene rearrangement was the strongest statistically independent predictor of OS (relative risk 3.4, P=0.004) and EFS (relative risk 2.5, P=0.015), and this also held true when the cell-of-origin signature detected by immunohistochemistry was included in the model.

Studienprotokoll der VISEP-Studie. Entgegnung der SepNet-Studiengruppe
SepNet - German Competence Network Sepsis

Abstract (Expand)

In the commentary by Zander et al. the authors appear concerned about the methods and results of our, at that time, unpublished sepsis trial evaluating hydroxyethyl starch (HES) and insulin therapy. … Unfortunately, the authors’ concerns are based on false assumptions about the design, conduct and modes of action of the compounds under investigation. For instance, in our study the HES solution was not used for maintenance of daily fluid requirements, so that the assumption of the authors that this colloid was used \textquotedblexclusively\textquotedbl is wrong. Moreover, the manufacturer of Hemohes, the HES product we used, gives no cut-off value for creatinine, thus the assumption that this cut-off value was \textquotedbldoubled\textquotedbl in our study is also incorrect. Other claims by the authors such as that lactated solutions cause elevated lactate levels, iatrogenic hyperglycemia and increase O(2) consumption are unfounded. There is no randomized controlled trial supporting such a claim - this claim is neither consistent with our study data nor with any credible published sepsis guidelines or with routine practice worldwide. We fully support open scientific debate. Our study methods and results have now been published after a strict peer-reviewing process and this data is now open to critical and constructive reviewing. However, in our opinion this premature action based on wrong assumptions and containing comments by representatives of pharmaceutical companies does not contribute to a serious, unbiased scientific discourse.

Effect of interleukin-10 gene polymorphisms on clinical outcome of patients with aggressive non-Hodgkin's lymphoma: an exploratory study.
GLA - German Lymphoma Alliance

Abstract (Expand)

PURPOSE: Current chemotherapy can achieve high response rates in aggressive non-Hodgkin's lymphoma (NHL), but the factors that influence regression and survival remain unknown. The present exploratory … study tested the hypothesis whether interleukin-10 (IL-10) polymorphisms predict clinical outcome, leukocytopenia, or infectivity during therapy. IL-10 was chosen because immune alterations are a major risk factor for NHL, and IL-10 is a cytokine involved in inflammatory processes associated with clinical outcome. EXPERIMENTAL DESIGN: Five hundred patients with aggressive NHL treated with CHOP/CHOEP were analyzed for IL-10 gene polymorphisms, including distal loci -7400InDel, -6752AT (rs6676671), and -6208CG (rs10494879) in comparison with proximal loci -3538AT (rs1800890), -1087AG (rs1800896), and -597AC (rs1800872) according to the incidence and outcome of the lymphoma. RESULTS: No differences in allele frequencies or haplotypes were found comparing a cohort of patients with aggressive NHL/diffuse large B-cell lymphoma with a healthy control group. Patients with aggressive NHL characterized by IL-10(-7400DelDel) had shorter overall survival periods compared with the other genotypes (P = 0.004). The 3-year rate is 43.4% for IL-10(-7400DelDel) and 73.4% for IL-10(-7400InIn) and IL-10(-7400InDel) together. A significant increased risk for event-free survival is found for carriers of the genotype IL-10(-6752TT-6208CC-3538AA) (P = 0.047). Multivariate analysis of IL-10(-7400) gene variation in relation to overall survival adjusted to international prognostic index revealed a relative risk of 1.9 for carriers of IL-10(-7400DelDel) (P = 0.037). No associations were found analyzing diffuse large B-cell lymphoma patients separately. CONCLUSION: Our results indicate that IL-10 gene variations could be associated to the clinical course of aggressive NHL, which points out the importance of host factors and respective genetic elements for treatment response.
