Bevacizumab efficacy in metastatic colorectal cancer is dependent on primary tumor resection.
Purpose Bevacizumab plus fluoropyrimidine-based chemotherapy is standard treatment for first-line and second-line metastatic colorectal cancer (mCRC). However, to date, there is no current biomarker predictive for the benefit of bevacizumab use for these patients. Preclinical data suggest that the presence of the primary tumor could be involved in less efficient antitumor activity of antiangiogenic agents, but no clinical data currently support this hypothesis. Methods We performed a retrospective analysis of factors associated with overall survival (OS) in a study cohort of 409 mCRC patients. Univariate and multivariate Cox proportional hazard regression models were used to assess the infl…
Bon usage des anticancéreux dans les tumeurs solides : impact des référentiels de bon usage
Resume Introduction Le bon usage des medicaments anticancereux est un enjeu majeur de pilotage des etablissements de sante. L’elaboration de referentiels de bon usage (RBU) est un dispositif specifique de notre systeme de sante. Objectif L’objectif principal de notre travail est de confronter les pratiques therapeutiques aux RBU. L’objectif secondaire est d’evaluer l’impact des RBU sur les recours « hors referentiel » en comparaison d’une etude similaire realisee en 2004. Patients et methode L’etude est realisee entre le 01/07/2008 et le 31/03/2009 sur deux centres de reference en cancerologie. Elle inclut 2289 patients representant 3187 recours a une molecule anticancereuse financee en sus…
Attachement et parcours de l’aidant face à l’épreuve du cancer
Resume Introduction Depuis le dernier plan cancer 2014–2019, l’evaluation des repercussions de la maladie chez les aidants est devenue essentielle. En effet, la qualite de la relation d’aide participe a la qualite de vie du malade. Dans ce contexte, l’objectif principal de cette etude etait de decrire l’evolution de l’attachement de l’aidant de patients ayant un cancer pendant les trois premieres annees d’accompagnement de la maladie. Methode Les aidants ont ete recrutes dans le cadre de l’etude ICE (Informal Carers of Elderly) et accompagnaient un proche, âge de plus de 60 ans, atteint d’un cancer colorectal, du sein ou de la prostate. Ils ont ete rencontres a domicile dans les trois mois …
Evaluation of efficacy and efficiency of a pragmatic intervention by a social worker to support informal caregivers of elderly patients (The ICE Study): study protocol for a randomized controlled trial
Medical progress and the lifestyle modification have prolonged life expectancy, despite the development of chronic diseases. Support and care for older subjects are often provided by a network of informal caregivers composed of family, friends and neighbors, who are essential in helping older persons to continue living at home. It has been shown that the extent and diversity of informal tasks may jeopardize the physical, mental and social wellbeing of caregivers. The aim of the Informal Carers of Elderly cohort is to define, through a longitudinal study, profiles of caregivers of older patients with a diagnosis of one of the following diseases: cancer (breast, prostate, colorectal), neurode…
Appropriate cytotoxic drugs usages in solid tumors: Impact of appropriate use referentials
Summary Background The appropriate use of anticancer drugs is at major stake of steering health facilities. French health authorities have specifically elaborated evidence-based principles and guidelines on good practice for the management of anticancer drugs called “referentiels de bon usage” (RBU in French). Objectives The primary aim of the survey is to confront therapeutic practices and PGU. The secondary objective is to evaluate the impact of PGU on “outside the prescribing guidelines” therapeutic use, as compared with a similar study conducted in 2004. Patients and methods The survey was conducted from 1st July 2008 to 31st March 2009 at two reference centers in cancer research, and i…
Enhanced emergence of antibiotic-resistant pathogenic bacteria after in vitro induction with cancer chemotherapy drugs.
International audience; BACKGROUND:Infections with antibiotic-resistant pathogens in cancer patients are a leading cause of mortality. Cancer patients are treated with compounds that can damage bacterial DNA, potentially triggering the SOS response, which in turn enhances the bacterial mutation rate. Antibiotic resistance readily occurs after mutation of bacterial core genes. Thus, we tested whether cancer chemotherapy drugs enhance the emergence of resistant mutants in commensal bacteria.METHODS:Induction of the SOS response was tested after the incubation of Escherichia coli biosensors with 39 chemotherapeutic drugs at therapeutic concentrations. The mutation frequency was assessed after …
Évaluation de l’impact de l’intervention d’un travailleur social auprès d’aidants informels de personnes âgées atteintes d’une pathologie chronique. Protocole de l’étude ICE : cohorte prospective multicentrique d’aidants informels en BFC
Introduction L’amelioration des conditions de vie et les progres medicaux ont permis un allongement de la duree de vie a des âges tres eleves, lequel a genere l’apparition et le developpement de maladies chroniques associees a des comorbidites. Dans ce contexte, la problematique de la dependance est devenue un enjeu majeur pour les politiques publiques. Depuis de nombreuses annees, elles traduisent leur volonte de faciliter le maintien au domicile le plus longtemps possible a des personnes âgees en perte d’autonomie. Ainsi, cette volonte de continuer a vivre a domicile, directement exprimee par les aines, repose en grande partie sur un reseau d’aides informelles (famille, amis, voisins). Le…
