Epidemiology and risk factors for oesophageal adenocarcinoma.
Oesophageal adenocarcinoma will soon cease to be a rare form of cancer for people born after 1940. In many Western countries, its incidence has increased more rapidly than other digestive cancers. Incidence started increasing in the Seventies in England and USA, 15 years later in Western Europe and Australia. The cumulative risk between the ages of 15 and 74 is particularly striking in the UK, with a tenfold increase in men and fivefold increase in women in little more than a single generation. Prognosis is poor with a 5-year relative survival rate of less than 10%. The main known risk factors are gastro-oesophageal reflux, obesity (predominantly mediated by intra-abdominal adipose tissues)…
Epidemiology and prognosis of synchronous and metachronous colon cancer metastases: a French population-based study.
Epidemiological data on synchronous and metachronous metastatic colon cancer are scarce. We assessed epidemiological characteristics and survival in synchronous and metachronous metastatic colon cancer in a French population.Our study included 932 cases of metastatic colon cancer diagnosed in 1999-2010 and registered in a population-based cancer registry; 758 were synchronous colon metastases and 174 metachronous metastases from resected primary colon cancers diagnosed in 1999-2005. Univariate relative survival was calculated and a multivariate model with proportional hazard applied to net survival by interval was used.Mean age at diagnosis was 71.1 years for patients with metachronous meta…
Conditional net survival: Relevant prognostic information for colorectal cancer survivors. A French population-based study
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…
Incidence and survival in late liver metastases of colorectal cancer
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…
Épidémiologie du cancer du pancréas
Actually, pancreatic cancer is a major challenge in digestive oncology. Its prognosis remains very poor with a five-year net survival less than 10%. Although if pancreatic cancer incidence was low, data from French digestive cancer registries show a dramatic increase in recent years, more marked in women (annual variation of +3.6% between 1982 and 2012) than in men (+2.3%). The currently recognized risk factors like tobacco or obesity cannot explain this evolving epidemiology. Moreover, progress in understanding pancreatic carcinogenesis is still insufficient. Except for familial aggregation, systematic screening couldn't be proposed.
Influence of sample return time and ambient temperature on the performance of an immunochemical faecal occult blood test with a new buffer for colorectal cancer screening.
IF 2.415; International audience; The haemoglobin concentration measured by faecal immunochemical tests (FIT) may be decreased in cases of delayed sample return or high temperature. It is an issue of great importance. The aim of this study was to investigate the effects of sample return time and of season on the performance of an FIT (FOB-Gold) with a new buffer. The study included 20 371 participants involved in the French organized colorectal cancer (CRC) screening programme. The probability of a positive screening test, detection rates and positive predictive values for CRC and advanced adenoma were analysed according to sample return time and season of screening. A sample of positive FI…
Risk factors for Coronavirus Disease 2019 (COVID-19) severity and mortality among solid cancer patients and impact of the disease on anticancer treatment: A French nationwide cohort study (GCO-002 CACOVID-19).
Background Cancer patients are thought to have an increased risk of developing severe Coronavirus Disease 2019 (COVID-19) infection and of dying from the disease. In this work, predictive factors for COVID-19 severity and mortality in cancer patients were investigated. Patients and Methods In this large nationwide retro-prospective cohort study, we collected data on patients with solid tumours and COVID-19 diagnosed between March 1 and June 11, 2020. The primary endpoint was all-cause mortality and COVID-19 severity, defined as admission to an intensive care unit (ICU) and/or mechanical ventilation and/or death, was one of the secondary endpoints. Results From April 4 to June 11, 2020, 1289…
