Breast cancer subtype of French women is not influenced by socioeconomic status: A population-based-study

2017

Context The molecular subtype of breast tumours plays a major role in cancer prognosis and treatment options. Triple negative tumours (TN) carry the worst prognosis and affects most frequently women of low socioeconomic status (SES). Studies have shown that non-biologic factors, such as the socioeconomic status could have an influence on tumour biology. To this date no study has been done investigating this association in French women. The objective is to study the association between the SES and the molecular tumour subtype of breast cancer patients in the French county of Cote d’Or. This study benefits from the population data from the Cote d’Or breast cancer registry known for its strict…

Trends in net survival from rectal cancer in six European Latin countries: results from the SUDCAN population-based study.

2016

Rectal cancer is a common and serious disease. The aim of the SUDCAN collaborative study was to compare the net survival from rectal cancer between six European Latin countries (Belgium, France, Italy, Portugal, Spain, and Switzerland) and provide trends in net survival and dynamics of excess mortality rates up to 5 years after diagnosis. The data were extracted from the EUROCARE-5 database. First, net survival was studied over the period 2000-2004 using the Pohar-Perme estimator. For trend analyses, the study-period was specific to each country. The results are reported from 1992 to 2004 in France, Italy, Spain, and Switzerland and from 2000 to 2004 in Belgium and Portugal. These analyses …

Time-to-cure and cure proportion in solid cancers in France. A population based study.

2019

In cancer care, the cure proportion (P) and time-to-cure (TTC) are important indicators for practitioners, patients, and healthcare policy makers. The recent definition of TTC as the time at which the probability of belonging to the cured group reaches 95% was used for the first time.The data stem from the common database of French cancer registries including 335,358 solid tumours diagnosed between 1995 and 2009 at 27 sites. P and TTC were estimated through a flexible parametric net survival cure model for each cancer site, sex, and age at diagnosis with acceptable assumption of cure (excess mortality rate ≤0.05).TTC was ≤5 years and P was80% for skin melanoma and thyroid and testis cancers…

Incidence of amyotrophic lateral sclerosis in Sicily: A population based study

2012

Our objective was to investigate incidence of amyotrophic lateral sclerosis (ALS) in Sicily, southern Italy, by means of a population based study. We included people with ALS resident in fi ve Sicilian provinces, whose onset occurred in the two-year period 2005 2006 (population at 31 December 2006: 3,481,096 inhabitants). A multisource case-fi nding procedure was adopted and patients were classifi ed as affected by ALS according to revised El Escorial criteria. During the two-year surveillance period, 97 patients meeting eligibility criteria included 57 males (58.8%) and 40 females (41.2%). Crude annual incidence rate was 1.4/100,000 person years (95% CI 1.33 1.47). The incidence rate was h…

Conditional net survival: Relevant prognostic information for colorectal cancer survivors. A French population-based study

2015

Abstract Background Traditionally, survival estimates have been reported as survival from the time of diagnosis. A patient's probability of survival changes according to time elapsed since the diagnosis and this is known as conditional survival. The aim was to estimate 5-year net conditional survival in patients with colorectal cancer in a well-defined French population at yearly intervals up to 5 years. Methods Our study included 18,300 colorectal cancers diagnosed between 1976 and 2008 and registered in the population-based digestive cancer registry of Burgundy (France). We calculated conditional 5-year net survival, using the Pohar Perme estimator, for every additional year survived afte…

Physical activity and depression: a large cross-sectional, population-based study across 36 low- and middle-income countries

2016

Objective: Physical activity (PA) is good for health, yet several small-scale studies have suggested that depression is associated with low PA. A paucity of nationally representative studies investigating this relationship exists, particularly in low- and middle-income countries (LMICs). This study explored the global association of PA with depression and its mediating factors. Method: Participants from 36 LMICs from the World Health Survey were included. Multivariable logistic regression analyses were undertaken exploring the relationship between PA and depression. Results: Across 178 867 people (mean ± SD age = 36.2 ± 13.5 years; 49.9% male), the prevalence of depression and the prevalenc…

Incidence of Acute Ischemic Stroke With Visible Arterial Occlusion

2020

Background and Purpose: Because of several methodological limitations, previous studies focusing on the prevalence of large vessel occlusion in ischemic stroke (IS) patients provided conflicting results. We evaluated the incidence of IS with a visible arterial occlusion using a comprehensive population-based registry. Methods: Patients with acute IS were prospectively identified among residents of Dijon, France, using a population-based registry (2013–2017). All arterial imaging exams were reviewed to assess arterial occlusion. Annual incidence rates of IS (first-ever and recurrent events) and IS with a visible occlusion were calculated. Results: One thousand sixty cases of IS were recorde…

Diagnostic Procedures in Ischaemic Stroke Patients with Dementia. A Population-Based Study

2012

Background Dementia is a frequent condition in stroke patients. Aims To investigate the effect of dementia on access to diagnostic procedures in ischaemic stroke patients. Methods All cases of ischaemic stroke from 2006 to 2010 were identified from the population-based Stroke Registry of Dijon, France. Patients' characteristics were recorded, as was the use of brain computed tomography scans, brain magnetic resonance imaging, electrocardiogram, echocardiography, and Doppler ultrasonography of the cervical arteries. Dementia was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders-IV criteria. Logistic regression models were used to evaluate the associations between d…
