Cohort study of occupational cosmic radiation dose and cancer mortality in German aircrew, 1960-2014.
2020
ObjectivesTo determine cancer mortality compared with the general population and to examine dose-response relationships between cumulative occupational radiation dose and specific cancer outcomes in the German aircrew cohort.MethodsFor a cohort of 26 846 aircrew personnel, standardised mortality ratios (SMR) were calculated. Dose-response analyses were carried out using Poisson regression to assess dose-related cancer risks for the period 1960–2014. Exposure assessment comprises recently available dose register data for all cohort members and newly estimated retrospective cabin crew doses for 1960–2003.ResultsSMR for all-cause, specific cancer groups and most individual cancers were reduced…
Incidence and Prognostic Value of FLT-3 and NPM1 Genes Abnormalities in Acute Myeloid Leukemia in the Côte D’or Population, France
2008
Abstract Context: In acute myeloid leukemia (AML), the recently described FLT-3 and NPM1 genes abnormalities were found to have a prognostic value in AML with normal karyotype and a specific therapeutic strategy was proposed according to these abnormalities. We look for the incidence and prognostic value of these abnormalities in cases diagnosed on a well defined population. Material and Methods: AML diagnosed according to WHO classification between 01/01/2001 and 31/12/2006 in the population of the Côte d’Or department, were included. Karyotype analyses were performed in 81% of the cases. The FLT3 D835 mutation, the FLT3 internal duplication (ITD) and the NPM1 mutation were systematically…
Extranodal Extension of Nodal Metastases Is a Poor Prognostic Indicator in Gastric Cancer: a Systematic Review and Meta-analysis.
2016
Introduction: The extranodal extension (ENE) of nodal metastases (the extension of neoplastic cells through the nodal capsule into the perinodal soft tissue) is a histological feature that has been considered a prognostic factor in several cancers, but the role in gastric cancer was not yet investigated. We aimed to investigate the prognostic role of ENE in patients affected by gastric cancer through a systematic review and meta-analysis. Material and Methods: Two independent authors searched major databases until 09/30/2015 to identify studies providing data on gastric cancer patients’ prognostic parameters and comparing patients with ENE (ENE+) vs intra-nodal extension (ENE−). The data we…
Prognostic implications of extranodal extension in node-positive squamous cell carcinoma of the vulva: A systematic review and meta-analysis
2016
Squamous cell carcinoma (SCC) of the vulva is the fourth most common gynecological cancer, usually staged with the TNM or FIGO systems. Since 2009, FIGO staging has taken the extranodal extension (ENE) of lymph node metastases into account. ENE is defined as the spread of a lymph node metastasis into surrounding soft tissue. Although the TNM and FIGO systems acknowledge the importance of ENE in SCC, no comprehensive studies have analyzed the prognostic impact of this parameter. We therefore queried the PubMed and SCOPUS databases from their inception up until 04/01/2015, adopting no language restrictions: all prospective studies reporting on prognostic parameters in patients with vulvar SCC…
Extranodal extension of nodal metastases is a poor prognostic moderator in non-small cell lung cancer: a meta-analysis
2018
Extranodal extension (ENE) of nodal metastasis is defined as the extension of metastatic cells through the nodal capsule into the perinodal tissue. This morphological parameter, recently proposed as an important prognostic factor in different types of malignancy, has not been included in the TNM staging system for non-small cell lung cancer (NSCLC). In this systematic review with meta-analysis, we weighted the prognostic role of ENE in patients with lymph node-positive NSCLC. Two independent authors searched SCOPUS and PubMed through 28 February 2017. Prospective and retrospective studies on NSCLC, comparing patients with presence of ENE (ENE+) ENE+) vs. only intranodal extension (ENE–) and…
Prognostic comparison of the pathological classifications of gastric cancer: a population-based study
1998
Aims There is controversy over the value of the pathological classifications of gastric carcinomas in the prediction of patient survival. This study was designed to assess the prognostic value of four widely used pathological classifications, in addition to classical prognostic factors. Methods and results Records from the population-based registry of digestive tract tumours in the department of Cote d'Or (France) have been analysed. All available histopathological slides of gastric cancer resected between 1976 and 1985 were reviewed and classified according to World Health Organization (WHO), Lauren, Ming and Goseki pathological coding systems. A relative survival analysis was performed us…
Hematopoietic and lymphatic cancers in patients with periodontitis : a systematic review and meta-analysis
2019
Background Numerous studies have explored the correlation of periodontal disease (PD) with risk of hematopoietic and lymphatic cancers, but the findings were inconsistent. Therefore, we did a meta-analysis to ascertain the correlation of PD with risk of incident hematopoietic and lymphatic cancers. Material and Methods The authors searched relevant studies in databases (PubMed, Web of Science, and MEDLINE). The summary relative risk (RR) along with 95% confidence interval (CI) was calculated by use of random or fixed effects models. Results Six studies were included in qualitative synthesis. The pooled analysis revealed that PD was significantly associated with an increased risk of hematopo…

 Consistency and Proportionality in Policy Decision-Making in Blood Safety: the Case for an All-Apheresis Platelet Supply in Germany
2013
SUMMARY Recently, German investigators presented the first mathematical model finding a significant increase in the risk of HIV, HCV, and HBV transmission when pools of 4 whole-blood-derived buffy-coat platelets, rather than 1 singledonor (apheresis) component, are used to provide one platelet dose. Based, in both cases, on mathematical models employing the incidence/window-period method, the relative risk of transmission from pooled versus apheresis platelets (2.2 or 2.75 for HIV, 2.7 or 3.375 for HCV, and 3.2 or 4.0 for HBV, with pools of 4 or 5 concentrates, respectively) is similar to the difference in risk before (versus after) introduction of HIV-1 and HCV RNA screening. The absolute …
Incidence and survival in late liver metastases of colorectal cancer
2014
Background and Aims Data concerning the risk of long-term liver metastasis following surgery of colorectal cancer in the general population are scarce. The 10-year incidence and prognosis of metachronous liver metastases remain unknown. Methods Among 4584 patients resected for cure for colorectal cancer recorded in two French digestive population-based cancer registries between 1985 and 2000, 602 presented metastases including liver metastases. Results The cumulated incidence of liver metastasis was 15% at 5 years and 17% at 10 years, and was mainly related to stage at diagnosis. The 10-year cumulative incidence was 6% for stage I and 30% for stage III. The hazard ratio was 3.2 [2.4–4.3] fo…
Impact of neoadjuvant chemotherapy on survival in breast cancer patients in daily practice: a population-based study
2013
This population-based study aimed to describe the effects of neoadjuvant chemotherapy (NC) on survival in breast cancer (BC) patients in daily practice. BC patients treated with NC followed by surgery and radiotherapy, were retrospectively selected from 1982 to 2005 using the Cote d’Or BC registry. These patients were matched for the baseline AJCC (American Joint Committee on Cancer) stage, age at diagnosis, date of diagnosis and oestrogens receptors status to those who had undergone surgery followed by adjuvant chemotherapy and radiotherapy. The prognostic effect of NC on survival in BC patients was assessed with relative survival (RS) analyses. From 1982 to 2005, 210 patients with BC diag…
