Access to care and prognosis in elderly with cancer : analysis of déterminants using data from cancer registries and cohort studies in Gironde, a French district

Le vieillissement de la population associé à un nombre croissant de cancers constituent une réalité épidémiologique qui soulève des interrogations sur l’accès aux soins et le pronosticdes sujets âgés avec un cancer, pour lesquels des disparités ont été mises en évidence. Toutefois, les études présentent plusieurs limites dont l’absence de facteurs spécifiques aux personnes âgées (PA). L’objectif de ce travail était d’étudier les déterminants sociodémographiques, socioéconomiques et cliniques de l’accès aux soins (stade de cancer, traitement) et du pronostic (déclin fonctionnel, survie) chez des PA atteintes d’un cancer. Les travaux ont été réalisés à partir de données issues de registres de cancers et de troiscohortes de PA en Gironde (486 patients de 65 ans et plus, période 2005-14). Les cohortes ont permis de disposer de données telles que le niveau d’éducation, le revenu, la prise demédicaments, la dépendance ou la démence. Selon l’objectif (accès/pronostic), nous avons utilisé différentes méthodes pour prendre en compte le type de données et de critères (régression logistique, modèles multiniveaux, modèles multi-état et de Cox). Notre population était composée pour plus de la moitié de PA de 80 ans et plus, de sexe masculin et ayant un niveau d’éducation supérieur au niveau primaire. Nous nous sommes d’abord intéressés aux déterminants de l’accès aux soins. Aucun déterminant d’un stade avancé de cancer au diagnostic n’a pu être mis en évidence, un niveau d’éducation faible était proche de la significativité pour les cancers avec un stade avancé (p=0,0671). Pour l’accès à un traitement du cancer, nous avons mis en évidence qu’un stade avancé (p=0,003) et la présence d’une démence (p=0,0109) étaient associés à un risque plus faible de recevoir un traitement. Nous avons ensuite étudié les déterminants du pronostic. Les sujets les plus âgés présentaient toujours un risque plus élevé de déclin fonctionnel (p<0,005), quel que soit le critère analysé. Les sujets ayant un faible niveau d’éducation (p=0,027), prenant plus de six médicaments par jour (p=0,047), présentant une démence (p<0,001) ou diagnostiqués à un stade avancé (p<0,001) avaient une probabilité de déclin fonctionnel plus importante, les résultats variant selon le critère. Enfin, à 12, 24 et 36 mois, la probabilité de survie globale était respectivement de 66, 57 et 48%. Le risque de décès était plus élevé chez les hommes (p=0,019), diagnostiqués à un stade avancé de cancer (p<0,001) et sans traitement du cancer (p<0,001), mais aussi chez les fumeurs (actuels et anciens) (p=0,019) et les PA dépendantes (p<0,001). En sus de déterminants classiques de l’accès aux soins ou du pronostic des cancers, nous avons mis en évidence pour les PA, le rôle des déficits cognitifs pour l’accès à un traitement ou sur le pronostic fonctionnel et celui de la dépendance sur la survie. Chez les PA avec un cancer, les facteurs spécifiques aux PA semblent donc essentiels à analyser. L’analyse des liens de causalité entre les déterminants de santé reste un sujet particulièrement intéressant dans cette population de PA comme pour les patients avec un cancer.The growing incidence of cancer associated to an aging population represents an epidemiologic reality that requires questioning access to care and prognosis in elderly with cancer, for which disparities have been highlighted. However, generally speaking, studies are limited in that they overlook geriatric-specific factors. The aim of this work was to study sociodemographic, socioeconomic and clinical determinants of access to care (cancer stage, cancer treatment) and prognosis (functional decline, survival) in elderly cancer patients. This research project has relied on data from cancer registries and three elderly cohort studies in the French department of Gironde (486 patients aged 65 and over from 2005 to 2014). The cohorts provided data such as education level, income, medication, dependency and dementia. Depending on the aim, we used different statistical methods to analyze different types of data and outcomes (logistic regression, multi-level model, multi-state model, Cox model). More than half of our population was aged 80 and over, male and had high education degrees. First, we studied determinants of access to care. No determinant of advance stage at diagnosis was found, but low education was close to significance for advanced stage (p=0.067). Concerning cancer treatment administration, advanced stage at diagnosis (p=0.003) and diagnosis of dementia (p=0.011) were associated with a lower risk of treatment administration. Second, we studied determinants of prognosis. Older old had higher risk of functional decline (p<0.001), regardless of the outcome. Subjects with low education (p=0.027), taking more than six daily drugs (0.047), presenting diagnosed dementia (p<0.001) or those with advanced cancer stage at diagnosis had higher risk of functional decline, results depending on outcome. At last, overall survival at 12, 24 and 36 months was 66, 55 and 48%, respectively. Risk of death was higher in men (p=0.019), in patients with advanced stage at diagnosis (p<0.001) or without treatment (p<0.001) in current and former smokers (p=0.019) and in dependent elderly patients (p<0.001). In addition to classical determinants of access to care and prognosis in cancer, we demonstrated the impact of cognitive impairment on treatment administration or functional prognosis, and that of dependency on survival. . It appears essential to consider geriatric specific factors in studies on the elderly with cancer population. The causality between health determinants is particularly interesting in the elderly as well as in the cancer populations

Several population-based studies have reported disparities in overall survival (OS) among older patients with cancer. However, geriatric syndromes, known to be associated with OS in the geriatric population, were rarely studied. Thus, our aim was to identify the determinants of OS among French older adults with cancer, including geriatric syndromes before cancer diagnosis. Using cancer registries, we identified older subjects (≥65 years) with cancer in three French prospective cohort studies on aging from the Gironde department. Survival time was calculated from the date of diagnosis to the date of all-cause death or to the date of last follow-up, whichever came first. Demographic and socioeconomic characteristics, smoking status, self-rated health, cancer-related factors (stage at diagnosis, treatment), as well as geriatric syndromes (polypharmacy, activity limitation, depressive symptomatology, and cognitive impairment or dementia) were studied. Analyses were performed using Cox proportional hazard models for the whole population, then by age group (65-84 and 85+). Among the 607 subjects included in the study, the median age at cancer diagnosis was 84 years. Smoking habits, activity limitations, cognitive impairment or dementia, advanced cancer stage and absence of treatment were significantly associated with lower OS in the analysis including the whole population. Women presented higher OS. Factors associated with OS differed by age group. Polypharmacy was inversely associated with OS in older adults aged 65-84 and 85 + . Our findings support that geriatric assessment is needed to identify patients at higher risk of death and that an evaluation of activity limitation in older adults is essential. Improving early detection could enable interventions to address factors (activity limitations, cognitive impairment) associated with OS, potentially reducing disparities and lead to earlier palliative care

BMJ Support Palliat Care

OBJECTIVES: Early palliative care improves the quality of life of older patients with cancer. This work aimed to analyse the effect of sociodemographic, geriatric, and tumour-related determinants on hospital-based palliative care (HPC) referral in older patients with cancer, taking into account competing risk of death. METHODS: Older adults with diagnosed cancer from 2014 to 2018 according to the general cancer registry of Gironde (French department) were identified in three population-based cohorts on ageing (PAQUID, 3C - Three City, AMI). Cause-specific Cox models focused on 10 usual determinants in geriatric oncology and palliative care: age, gender, living alone, place of residency, tumour prognosis, activities of daily living (ADL) and instrumental-ADL (IADL) limitations, cognitive impairment, depressive disorders, and polypharmacy. RESULTS: 131 patients with incident cancer (mean age: 86.2 years, men: 62.6%, poor cancer prognosis: 32.8%) were included, HPC occurring for 26 of them. Unfavourable cancer prognosis was a key determinant for HPC referral (HR 7.02, 95% CI 2.86 to 17.23). An altered IADL score was associated with precocious (first year) referral (HR 3.21, 95% CI 1.20 to 8.64, respectively). Women had a higher rate immediately (first week) after diagnosis (HR 8.64, 95% CI 1.27 to 87.27). CONCLUSIONS: Cancer prognosis, functional decline and gender are independent factors of HPC referral in older patients with cancer. These findings may help for a better anticipation of the healthcare pathway

BACKGROUND: Previous studies have reported on the higher risk of functional decline among older patients with cancer. However, few have focused on factors of functional decline in older persons with cancer and are mainly hospital-based and focus on consequences of cancer treatment. The aim of the study was to identify determinants of functional decline in older subjects with cancer in a population-based study. METHODS: Using cancer registries, we identified older subjects (age>/=65years) with cancer in three prospective cohort studies from Gironde, a French department. Functional status was measured using the Instrumental Activities of Daily Living (IADL) and the basic Activities of Daily Living (ADL) scales, and functional decline was measured between cancer pre- and post-diagnosis visits. Studied variables were demographic and socioeconomic (age at diagnosis, sex, living alone, education), cancer-related (stage at diagnosis, treatment received), smoking status, health-related (polypharmacy, depressive symptomatology), and geriatric-specific (cognitive impairment or dementia). Analyses were performed using logistic regression models. RESULTS: Age (>/=85years), cognitive impairment or dementia, and advanced stage at diagnosis were associated with a higher risk of ADL limitations, whether considering death or not. Age (>/=85years), education and polypharmacy were associated with a higher risk of ADL and/or IADL limitations. CONCLUSIONS: We identified factors that could impact on ADL and/or IADL limitations in older patients with cancer. The information on these determinants is useful in clinical settings to identify patients with cancer at high risk of functional decline

J Pain Symptom Manage

CONTEXT: More than half of new cancer cases occurred in older adults. Older patients with cancer are particularly at risk of physical, psycho-existential or socio-familial suffering as defined by the concept of Serious Health-related Suffering (SHS). OBJECTIVES: To assess the direct and indirect effects of physical, psycho-existential and socio-familial dimensions of suffering on cancer treatability, supportive care needs and 12-month mortality in older patients with cancer. METHODS: We included patients with cancer aged 70 years and over from the Elderly Cancer Patients cohort (ELCAPA, Ile-de-France), referred for geriatric assessment between 2007 and 2019 before cancer treatment. Structural equation modelling examined the direct and indirect relationships between SHS dimensions (latent variables), patients' characteristics (age, sex, tumor location and metastatic status, comorbidity, period of care), and outcomes. RESULTS: The analysis included 4,824 patients (mean age: 82.2 ± 4 years; women: 56%; main cancer sites: breast [22.3%], colorectal [15.2%], prostate [8.5%], and lung [6.8%]; metastatic cancer: 46%). Physical suffering had direct pejorative effects on cancer treatability, and mortality (standardized coefficient [SC] = 0.12 [P < 0.001], SC = 0.27 [P < 0.001], respectively). Psycho-existential and socio-familial sufferings had indirect pejorative effects on survival through decreased cancer treatability (SC = 0.08 [P < 0.001], SC = 0.03 [P < 0.001], respectively). Psycho-existential dimension had the main direct effect size on supportive care needs (SC = 0.35 [P < 0.001]) and was interrelated with physical suffering. CONCLUSION: Physical suffering has direct pejorative effect on survival. All dimensions indirectly decrease survival due to poorer cancer treatability. Our findings support concomitant management of physical and psycho-existential suffering

Repenser la prise en charge des sujets âgés atteints d’un cancer : propositions du groupe Priorités Âge Cancer

International audienceThe growing incidence of cancer associated with an aging population implies important health challenges that require questioning on the care management of older adults with cancer. There is a need to rethink the care management of older cancer patients with patient-centered decisions and an adjustment of the care pathway for this population. The Priorities Age Cancer (PAC) French group, made up of physicians, pharmacists and researchers in geriatric oncology, set up proposals to answer this need. First, the heterogeneity and the specificities of older adults as well as their preferences regarding cancer treatment goals, care management decisions must be patient-centered. The frailty screening tools should be generalized in clinical practice to provide geriatric assessment-guided recommendations and help for treatment decisions, and patients' involvement and shared decision should be developed. Second, older adults with cancer confront a complex health care system that demands a high level of health literacy. The caregivers, playing an essential role, may not be prepared for all these challenges. Thus, there is a need to promote health literacy by patient education, and patient-experts should be involved in health pathway. Third, there is a need to deal with dedicated partners and adjust the care pathway. New pathway careers as case-management nurses and specialized pharmacists should be involved in patient care and may play a central role together with other careers. Community-Hospital coordination should also be reinforced.Plus de la moitié des cancers sont diagnostiqués chez des sujets âgés, et cette part va croître dans les prochaines années. La prise en charge des patients âgés atteints d’un cancer constitue un défi majeur, qui nécessite de placer le patient au cœur des décisions et de réorganiser le parcours de soins, en repensant la collaboration entre les différents partenaires. Le groupe Priorités Âge Cancer, composé de praticiens, de pharmaciens et de chercheurs en oncogériatrie, a émis plusieurs propositions afin de répondre à ces besoins. Considérant l’hétérogénéité et les spécificités des sujets âgés, mais également leurs préférences, les décisions thérapeutiques doivent être individualisées. Une gradation coordonnée des soins doit être réalisée en généralisant les outils de repérage de la fragilité. L’implication des patients doit être renforcée afin de développer une meilleure décision partagée. Les patients âgés sont confrontés à un système de soins complexe qui exige un niveau élevé de littératie pour comprendre les traitements et les différentes étapes du parcours de soins. Les aidants participent à la prise en charge de leurs proches, mais peuvent ne pas être préparés à relever les défis, que ce rôle essentiel implique. Il est nécessaire de renforcer l’information des patients, et promouvoir le rôle des patients experts, mais également de soutenir, former et intégrer les aidants au parcours de soins. Il semble également nécessaire d’impliquer de nouveaux partenaires comme les pharmaciens ou les infirmiers formés à la gestion de cas. Le lien ville-hôpital doit être renforcé, notamment avec les acteurs du premier recours

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. Vital status for each patient was actively followed up to June 30, 2013. Net survival (NS) was estimated using the unbiased Pohar-Perme method. RESULTS: Overall, 4202 patients were included. NS declined with increasing age at diagnosis. According to topographic groups, large 5-year NS disparities were observed, ranging from 47% among women with gynecologic sarcomas to 89% among patients with skin sarcomas. Patients with soft tissue, bone, and gastrointestinal sarcomas had 5-year NS rates of 53%, 61%, and 70%, respectively. Similar heterogeneity was observed according to histologic subtypes, with 5-year NS ranging from 19% for patients with angiosarcomas to 96% for patients with dermatofibrosarcomas. Patients with sarcoma who displayed missense mutations had a better 5-year NS (74%); those with MDM2-amplified sarcomas had the worst NS (45%). CONCLUSIONS: NS rates in patients with sarcoma are presented here for the first time based on the 2020 World Health Organization classification applied to population-based registry data. Large prognostic heterogeneity was observed based on age, topographic and histologic groups, and genomic alteration profiles, constituting a benchmark for future studies and clinical trials

AIM: To describe first-line treatment patterns, overall survival (OS) and real-world progression-free survival (rwPFS) in young women (<40) with metastatic breast cancer (mBC), as compared to women aged 40-69. MATERIALS AND METHODS: Data on adult women diagnosed with mBC (2008-2017) were extracted from the ESME mBC database (NCT03275311) which includes consecutive patients starting first-line metastatic treatment in one of the 18 French Comprehensive cancer centers. We reported first-line therapeutic strategy and prognostic factors of OS and rwPFS for women aged < 40 and 40-69. RESULTS: In total, 14,897 mBC women were included (1512 aged <40). HR+ /HER2- mBC was the most frequent subtype. First-line treatment differed between young patients and older ones for HR+ /HER2- and Triple Negative (TN) mBC. Median OS for women aged < 40 and 40-69, respectively, was 46.9 and 46.2 months for HR+ /HER2- mBC; 13.5 and 15.2 for TN mBC; and, 60.7 and 55.1 for HER2 + mBC. Median rwPFS under first line treatment was 11.6 and 11.9 months for HR+ /HER2- in women aged < 40 and 40-69, respectively; 5.5 and 5.9 for TN, and, 13.3 and 12.9 for HER2 + . Factors associated with shorter OS and rwPFS were similar for both women aged < 40 and 40-69 and included ≥ 3 metastatic sites, visceral metastases, and longer MFI, with time-varying effects observed for several prognostic factors. CONCLUSION: Young women presented more frequently with TN and HER2 + subtypes and aggressive mBC than women aged 40-69 did. Prognostic factors of OS and rwPFS were quite similar between age groups and mBC subtypes
