Estimation and prognosis value of elderly colorectal cancer patients' quality of life. : A population-based study
Colorectal cancer is one of the most common malignancies in France and predominantly affects older patients. Few studies evaluating baseline quality of life of those patients, its short term evolution and its prognosis value on patients' survival have been performed in the context of a population-based study. This work is based on a prospective longitudinal cohort study performed by the Burgundy Digestive Cancer Registry. All patients aged 65 and over, diagnosed with a new colorectal cancer and registered by the Registry between 2003 and 2005 were eligible. Among the 401 eligible patients, 246 fulfilled at least one questionnaire. Non-respondents were older and diagnosed with a more advance…
Health-related quality of life is a prognostic factor for survival in older patients after colorectal cancer diagnosis: A population-based study
International audience; Background: Studies carried out in the context of clinical trials have shown a relationship between survival and health-related quality of life in colorectal cancer patients.Aims: We assessed the prognostic value of health-related quality of life at diagnosis and of its longitudinal evolution on survival in older colorectal cancer patients. Methods: All patients aged >= 65 years, diagnosed with new colorectal cancer between 2003 and 2005 and registered in the Digestive Cancer Registry of Burgundy were eligible. Patients were asked to complete the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at inclusion, three, six …
Estimation of National Colorectal-Cancer Incidence Using Claims Databases
Background.The aim of the study was to assess the accuracy of the colorectal-cancer incidence estimated from administrative data.Methods.We selected potential incident colorectal-cancer cases in 2004-2005 French administrative data, using two alternative algorithms. The first was based only on diagnostic and procedure codes, whereas the second considered the past history of the patient. Results of both methods were assessed against two corresponding local cancer registries, acting as “gold standards.” We then constructed a multivariable regression model to estimate the corrected total number of incident colorectal-cancer cases from the whole national administrative database.Results.The firs…
