Surgical patterns of care of pancreatic cancer. A French population-based study.

Introduction: Surgical resection is the standard recommended treatment in localized pancreatic cancer. The benefit of neoadjuvant chemotherapy is still debated. The aim of this population-based study was to describe the pancreatic cancer surgical management.

Access to primary care and mortality in excess for patients with cancer in France: Results from 21 French Cancer Registries.

Background: The impact of geographical accessibility on cancer survival has been investigated in few studies, with most research focusing on access to reference care centers, using overall mortality and limited to specific cancer sites. This study aims to examine the association of access to primary care with mortality in excess of patients with the 10 most frequent cancers in France, while controlling for socioeconomic deprivation.

Methods: This study included a total of 151,984 cases diagnosed with the 10 most common cancer sites in 21 French cancer registries between 2013 and 2015.

Incidence, initial management and survival of high-risk non-muscle invasive bladder cancer in Northern France.

Objective: Information on bladder cancer (BC) according to the risk scoring for recurrence or progression in a general population is scarce despite its clinical relevance. The objective was to describe the characteristics of incident BC in a general population, with a focus on the initial management of high-risk non-muscle invasive BC (HR-NMIBC).

Materials: BC incident in 2011-2012 recorded in a population-based cancer registry were studied.

Practice patterns and survival outcomes for muscle-invasive bladder cancer: real-life experience in a general population setting.

Bladder cancer (BC) is a common malignancy in Europe and North America. Among BCs, muscle-invasive BCs (MIBCs) are distinguished, as they require aggressive treatment due to their spreading potential and poor prognosis. Despite its clinical relevance, little information on MIBC in a general population setting is available.

Net survival in colon and rectal cancer by stage according to neoadjuvant treatment. A French population-based study.

Aim: Real-life estimations of survival by stage in colorectal cancer are scanty. We estimated population-based net survival by pathological stage and location, and for rectal cancer by patterns of evolution according to clinical and pathological stage with regard to neoadjuvant therapy.

Method: Age-standardized net survival was estimated on 19,630 colorectal cancers diagnosed between 2009 and 2015.

Validation of an algorithm for identifying incident cancer cases based on long-term illness and diagnosis related group program data from the French National Health Insurance Information System (SNDS).

Purpose: Three generic claims-based algorithms based on the Illness Classification of Diseases (10th revision- ICD-10) codes, French Long-Term Illness (LTI) data, and the Diagnosis Related Group program (DRG) were developed to identify retirees with cancer using data from the French national health insurance information system (Système national des données de santé or SNDS) which covers the entire French population. The present study aimed to calculate the algorithms' performances and to describe false positives and negatives in detail.

Methods: Between 2011 and 2016, data from 7544 participants of the French retired self-employed craftsperson cohort (ESPrI) were first matched to the SNDS data, and then toFrench population-based cancer registries data, used as the gold standard.

Evolution of the Incidence of Oral Cavity Cancers in the Elderly from 1990 to 2018.

Objectives: To describe the evolution of the incidence of oral cavity cancers (OCC) among elderly patients in France between 1990 and 2018 and to compare it to the incidence of other cancers sharing the same main risk factors.

Material And Methods: The incidence of cancers in mainland France from 1990 to 2018 was estimated from incidence data observed in every cancer registry of the Francim network. Incidence was modeled by a 2-dimensional penalized spline of age and year of diagnosis, associated with a random effect corresponding to the registry.

Overall and net survival of patients with sarcoma between 2005 and 2010: Results from the French Network of Cancer Registries (FRANCIM).

Background: Sarcomas are rare, heterogeneous, ubiquitously localized malignancies with many histologic subtypes and genomic patterns. The survival of patients with sarcoma has rarely been described based on this heterogeneity; therefore, the authors' objective was to estimate survival outcomes in patients who had sarcomas using the 2020 version of the World Health Organization classification of soft tissue and bone tumors.

Methods: Patients older than 15 years who had incident sarcoma diagnosed between 2005 and 2010 were extracted from 14 French population-based cancer registries covering 18% of the French metropolitan population.

To what extent do age, stage and treatment influence survival after invasive cervical cancer: a French population-based study.

Purpose: In an attempt to understand why cervical cancer (CC) survival is decreasing with diagnosis period among older women in France, this study aimed to estimate the effects of main prognostic factors on net survival in CC according to age.

Methods: French cancer registries databases were used to retrospectively analyze women diagnosed with CC in 2011-2012. Net survival was estimated with the Pohar-Perme method and prognostic factors (socio-demographic, clinical variables, stage at diagnosis, therapeutic management) were analyzed with Lambert and Royston's flexible parametric model.

Cancer incidence and mortality trends in France over 1990-2018 for solid tumors: the sex gap is narrowing.

Objective: To analyze trends in cancer incidence and mortality (France, 1990-2018), with a focus on men-women disparities.

Methods: Incidence data stemmed from cancer registries (FRANCIM) and mortality data from national statistics (CépiDc). Incidence and mortality rates were modelled using bidimensional penalized splines of age and year (at diagnosis and at death, respectively).

Cancer Among Adolescents and Young Adults Between 2000 and 2016 in France: Incidence and Improved Survival.

This study was undertaken to determine cancer survival and describe the spectrum of cancers diagnosed among French adolescent and young adult (AYA) population. All cases of cancer diagnosed in 15-24 years, recorded by all French population-based registries (18% of the French population), over the 2000-2016 period, were included. Age-standardized incidence rates, conventional annual percentage change (cAPC) of incidence over time, and 5-year overall survival (5yOS) were calculated.

Incidence and time trends of sarcoma (2000-2013): results from the French network of cancer registries (FRANCIM).

Background: The exhaustive collection of new sarcoma cases and their second histologic review offer a unique opportunity to study their incidence and time trends in France according to the major subtypes.

Methods: Data were collected from population-based cancer registries covering 22% of the French population. Crude and world age-standardized incidence rates (ASR) were estimated according to anatomic, histological and genetic groups, age and sex over the 2010-2013 period.

Population-based incidence of lymphomas in the French Nord-Pas-de-Calais region between 2001 and 2005: Annual estimations and spatial analysis.

Background: Non-Hodgkin's lymphomas (NHL) are the seventh most commonly diagnosed cancer in France. Nord-Pas-de-Calais is ranked as the region with the highest incidence of cancers and deaths by cancer in France. With its rich industrial past and its contrasted population densities between urban and rural territories, Nord-Pas-de-Calais represents a geographic area of interest to study the overall incidence of NHL and examine spatial variation of NHL incidence between the 170 cantons of the region.

Completeness of a newly implemented general cancer registry in northern France: Application of a three-source capture-recapture method.

Background: Completeness, timeliness and accuracy are important qualities for registries. The objective was to estimate the completeness of the first two years of full registration (2008/2009) of a new population-based general cancer registry, at the time of national data centralisation.

Methods: Records followed international standards.

Musculoskeletal pain at various anatomical sites and socioeconomic position: Results of a national survey.

Background: Prevalence of musculoskeletal pain according to sites of pain and associated factors in the community has not been thoroughly documented. The association between pain and socioeconomic position has been studied by several authors, but without details in most studies regarding sites of pain, whereas the relations with social position could differ according to the site of pain. The objective of this study was to explore these differences in the community in France.

Socioeconomic disparities in gait speed and associated characteristics in early old age.

Background: A few studies have documented associations between socioeconomic position and gait speed, but the knowledge about factors from various domains (personal factors, lifestyle, occupation…) which contribute to these disparities is limited. Our objective was to assess socioeconomic disparities in usual gait speed in a general population in early old age in France, and to identify potential contributors to the observed disparities, including occupational factors.

Methods: The study population comprised 397 men and 339 women, aged 55 to 69, recruited throughout France for the field pilot of the CONSTANCES cohort.

Occupational biomechanical exposure predicts low back pain in older age among men in the Gazel Cohort.

Purpose: Occupational biomechanical exposures are considered as risk factors for low back pain in the working population. It has also been suggested that their effects persist after retirement. Our objectives were to assess the role of past biomechanical occupational exposure on low back pain in early old age among male participants of the Gazel Cohort.

[Elements of completeness and results of the first year of registration of the "Registre général des cancers de Lille et de sa région"].

Background: In 2005, following the first cancer plan of the national health authorities, a general cancer registry was established in northern France, in a territory designated as a "zone in proximity to the city of Lille" (ZPL). The aim of the present work was to evaluate the completeness of the registry's first year of incident cancer registration (2005) and to compare the observed cancer incidence in the "ZPL" with the estimated incidence in France.

Methods: Completeness was assessed using the average number of sources per case, the percentage of histological verification and a method of independent case ascertainment (mortality/incidence ratio).

Low back pain around retirement age and physical occupational exposure during working life.

Background: Physical occupational exposure is a risk factor for low back pain in workers but the long term effects of exposure remain unclear. As several countries consider increasing the retirement age, further information on this topic is relevant. This study aimed to describe the prevalence of low back pain among middle aged and aging individuals in the general French population according to physical occupational exposure and retirement status.

[Personal and occupational factors associated with low-back pain in a general working population in France].

Background: Low-back pain is a major public health concern because of its socioeconomic burden, especially for chronic forms. The purpose of this study was to analyse the associations between low-back pain and occupational and personal factors, with a special focus on interactions between age and occupational exposures.

Methods: The study population comprised a sample of 3958 and 4526 working women and men aged 30 to 59 derived from a national health survey (2002-2003 EDS).
