[Incidence, mortality and prevalence of cancers in metropolitan France]. / Incidence, mortalité et prévalence des cancers en France métropolitaine.

Incidence, mortality and prevalence of cancers in metropolitan France. About 400,000 new people are diagnosed with cancer every year in metropolitan France, including 53.5% men and 46.5% women. Cancer is also the cause of almost 150,000 annual deaths of which 56% occur in men and 44% in women. Nearly 3.8 million people (1.8 million men and 2.0 million women) aged 15 and over have had cancer during their lifetime and are alive in 2017, or 7.0 % of the population aged 15 and over.

Incidence, mortalité et prévalence des cancers en France métropolitaine. Près de 400 000 nouvelles personnes sont diagnostiquées avec un cancer chaque année en France métropolitaine dont 53,5 % d'hommes et 46,5 % de femmes. Le cancer est également la cause d'environ 150 000 décès annuels parmi lesquels 56 % surviennent chez l'homme et 44 % chez la femme. On estime que près de 3,8 millions de personnes (1,8 million d'hommes et 2,0 millions de femmes) de 15 ans et plus ont eu un cancer au cours de leur vie et sont en vie en 2017, soit 7,0 % de la population de 15 ans et plus.

Febrile neutropenia in adjuvant and neoadjuvant chemotherapy for breast cancer: a retrospective study in routine clinical practice from a single institution.

BACKGROUND: Febrile neutropenia (FN) is one of the most common and most critical adverse effects of chemotherapy. Despite many existing guidelines based on the use of granulocyte-colony stimulating factor (G-CSF), FN continues to impair the quality of life and interfere with the treatment of many patients. The purpose of this study was to assess the incidence and management of FN associated with chemotherapy for early breast cancer in routine clinical practice. METHODS: All patients with early-stage breast cancer (ESBC) treated by chemotherapy at Institut Curie, Hôpital René Huguenin, in 2014 were retrospectively included. The incidence and management of FN were reported. Risk factors associated with FN were studied by robust-error-variance Poisson regression. RESULTS: A total of 524 patients received either neoadjuvant (N = 130) or adjuvant chemotherapy (N = 394). Most patients (80%) were treated with a combination of 5-fluorouracil, epirubicin, and cyclophosphamide (FEC100; 3 cycles) followed by docetaxel 100 mg/m2 (D; 3 cycles). The overall incidence of FN was 17%. Eighteen percent of patients received primary prophylaxis (PP) for FN with G-CSF, using pegfilgrastim in 64% of cases and 74% of patients over the age of 70 received PP. Less than 5% of patients who received PP experienced FN. Recurrent FN after secondary prophylaxis was observed in 9% of patients. Forty-seven percent of cases of FN occurred after the first cycle and 30% occurred after the fourth cycle, corresponding to D ± trastuzumab (T). The FEC100 regimen was associated with a relative risk of FN of 1.98 (p = 0.09). Autoimmune (AI) and inflammatory diseases were associated with a higher risk of FN (RR 3.08; p < 0.01). No significant difference in the incidence of FN was observed between adjuvant and neoadjuvant chemotherapy. FN was managed on an outpatient basis in 72% of cases. Outpatients with FN were mainly treated by a combination of amoxicillin-clavulanic acid and ciprofloxacin. Dose reduction or chemotherapy regimen modification were necessary in 25% of patients after FN. No toxic death was reported. CONCLUSION: The incidence of FN induced by adjuvant/neoadjuvant chemotherapy in ESBC is higher in routine clinical practice than in clinical trials. AI or inflammatory diseases were significant independent risk factors for FN. Primary prophylaxis in patients at risk (elderly, comorbid patients), especially treated with the FEC regimen, is the keystone of management of this adverse effect. Prevention and management of FN to ensure the patient's safety and quality of life are a major issue for both medical oncologists and supportive care physicians.

Systematic review and meta-analysis of phase I/II targeted therapy combined with radiotherapy in patients with glioblastoma multiforme: quality of report, toxicity, and survival.

To perform a systematic review and meta-analysis of severe adverse events (SAE) reported in early trials combining molecularly targeted therapies (MTT) with radiotherapy (RT), and to compare them to standard therapy. A summary data meta-analysis was performed and compared to the historical standard. Inclusion criteria were phase I and/or II trials published between 2000 and 2011, with glioblastoma multiforme patients treated with RT and MTT. Pooled incidence rates (IR) of SAE were estimated as well as the pooled median progression-free survival (PFS) and overall survival (OS). Nineteen prospective trials (9 phase I, 1 phase I/II and 9 phase II) out of 29 initially selected were included (n = 755 patients). The exact number of patients who had experienced SAE was mentioned in 37 % of the trials, concerning only 17 % of the patients. Information such as the period during which adverse events were monitored, the planned treatment duration, and late toxicity were not reported in the trials. The pooled IR of overall SAE was 131.2 (95 % CI 88.8-193.7) per 1000 person-months compared to 74.7 (63.6-87.8) for standard therapy (p < 0.01). Significant differences were observed for gastrointestinal events (p = 0.05) and treatment-related deaths (p = 0.02), in favour of standard therapy. No significant difference was observed in PFS and OS. Reporting a summary of toxicity data in early clinical trials should be stringently standardized. The use of MTT with RT compared to standard therapy increased SAE while yielded comparable survival in glioblastoma multiforme patients.

Quality comparison of electronic versus paper death certificates in France, 2010.

BACKGROUND: Electronic death certification was established in France in 2007. A methodology based on intrinsic characteristics of death certificates was designed to compare the quality of electronic versus paper death certificates. METHODS: All death certificates from the 2010 French mortality database were included. Three specific quality indicators were considered: (i) amount of information, measured by the number of causes of death coded on the death certificate; (ii) intrinsic consistency, explored by application of the International Classification of Disease (ICD) General Principle, using an international automatic coding system (Iris); (iii) imprecision, measured by proportion of death certificates where the selected underlying cause of death was imprecise. Multivariate models were considered: a truncated Poisson model for indicator (i) and binomial models for indicators (ii) and (iii). Adjustment variables were age, gender, and cause, place, and region of death. RESULTS: 533,977death certificates were analyzed. After adjustment, electronic death certificates contained 19% [17%-20%] more codes than paper death certificates for people deceased under 65 years, and 12% [11%-13%] more codes for people deceased over 65 years. Regarding deceased under and over 65 respectively, the ICD General Principle could be applied 2% [0%-4%] and 6% [5%-7%] more to electronic than to paper death certificates. The proportion of imprecise death certificates was 51% [46%-56%] lower for electronic than for paper death certificates. CONCLUSION: The method proposed to evaluate the quality of death certificates is easily reproducible in countries using an automatic coding system. According to our criteria, electronic death certificates are better completed than paper death certificates. The transition to electronic death certificates is positive in many aspects and should be promoted.

[Community health workers in HIV/AIDS care]. / Les agents de santé communautaire dans la prise en charge thérapeutique du VIH/sida.

INTRODUCTION: Faced with the lack of human resources manage people living with HIV/AIDS (PLWHA) in developing countries, community health workers (CHWs) provide support to health professionals. The objective of this study was to describe the characteristics of CHWs and study the impact of their intervention on HIV care. A literature search was performed on Pubmed and the websites of international organizations. METHODS: A literature review was conducted, including studies describing the impact of the CHWs' intervention on the care of PLWHA. RESULTS: Thirteen articles were selected concerning twelve studies. The names and functions of CHWs are multiple; training and remuneration are very heterogeneous. Nevertheless, the impact of their intervention appears to be positive. Trials comparing community-based care versus hospital care show no difference between the two in terms of survival, retention, viral load or CD4 counts. The support provided by CHWs improves quality of life, compliance and self-confidence and decreases stigma (qualitative studies). It also allows coverage of previously remote areas. CONCLUSION: CHWs have various names, functions, formations and salaries. Their actions appear to have a positive impact both on the therapeutic management of PLHIV and on strengthening health systems. Recognition of CHWs by health systems remains marginal and remains a public health priority.

Lymphocele and ovarian cancer: risk factors and impact on survival.

INTRODUCTION: We describe the incidence, impact on survival, and the risk factors for symptomatic lymphoceles in patients with ovarian cancer. METHODS: This retrospective study includes patients with ovarian cancer who had complete cytoreductive surgery and para-aortic and pelvic lymphadenectomy performed in our institute from 2005 to 2011. Patients were classified into two groups: patients with symptomatic lymphoceles and a control group. RESULTS: During the study period, 194 patients with epithelial ovarian cancer underwent cytoreductive surgery and a lymphadenectomy without macroscopic residual disease. Fifty-four patients had symptomatic lymphoceles (28%). In the multivariate analysis, only supraradical surgery was significantly and independently associated with the risk of symptomatic lymphoceles occurring postoperatively. Median follow-up was 24.8 months (range, 1-74 months). Survival rates were not significantly different between the symptomatic lymphocele group and the control group. Two-year disease-free survival rates were 54% for the lymphocele group and 48% for the control group. Two-year overall survival rates were 90% for the lymphocele group and 88% for the control group. CONCLUSIONS: Symptomatic lymphoceles occur frequently after cytoreductive surgery in ovarian cancer. Supraradical surgery is an independent risk factor. The occurrence of symptomatic lymphoceles does not decrease survival. Nevertheless, further studies are needed to reduce the risk of lymphoceles in such patients.

Breast cancer screening: Impact on care pathways.

BACKGROUND: Controversy persists concerning screening programs (SPs), related to a potential risk of overdiagnosis or the impact on survival. One of the main questions to be addressed concerns the aggressiveness of the related treatments. METHODS: Using the "Cancer Cohort," a national-based cohort (medico-administrative database), all women between the ages of 50 and 74 years and treated in 2014 for incident breast cancer were compared, according to whether their diagnosis was made following a mammogram performed within the framework of the SP (SP group) or outside it (NSP group). RESULTS: A total of 23 788 women were identified: 13 530 (57%) in the SP group and 10 258 (43%) in the NSP group. The women in the SP group had a higher rate of in situ or localized invasive breast cancer. They had a higher rate of breast-conserving surgery (82% vs 70%), and a lower rate of chemotherapy (34% vs 53%). These findings were observed irrespective of the stage. They had a higher rate of pathways involving breast-conserving surgery followed by radiotherapy. Among women with metastatic cancer, those in the SP group had a lower proportion of liver, lung, brain, and bone metastases, and a higher proportion of lymph node metastases (other than axillary), irrespective of the time to onset of the metastases. CONCLUSION: The women in whom cancer was diagnosed following a mammogram performed in the context of the SP had less advanced cancer and less aggressive treatments. This observational study helps illustrate the benefit of the SP in France using a different approach.

Fertility preservation and cancer: How many persons are concerned?

OBJECTIVE: A significant proportion of cancer survivors experience chronic health sequelae, one of them being fertility impairment. However, even if many reports, guidelines and positions papers focus on fertility preservation and its needs, access to fertility preservation is not currently offered to all the patients concerned, and the targeted population is not well counted. STUDY DESIGN: A cross sectional study was conducted using the French cancer cohort, a cohort covering the whole French population and including around 7 million of cancer patients. Women under the age of 40 and men under the age of 60 included in the cancer cohort in 2013 who had, in the first year, cancer surgery, chemotherapy or radiotherapy were considered. Patients treated by surgery alone for cancers in locations distant from the reproductive organs, or being treated for a cancer the past 3 years were excluded. The number of patients concerned by fertility preservation was estimated at a national and regional level, and by cancer types. RESULTS: 40,000 patients - 30,000 men under the age of 60 years and 10,000 women under the age of 40 years - were identified. A second estimation concerning women under the age of 35 and men under 50 reduced the number of patients to 17,200-10,400 men and 6800 women. The most frequent locations were malignant neoplasm of lymphoid and hematopoietic tissue, lung cancer, cervix uteri, prostate and colorectal cancer. In 2014, around 5 400 persons had a preservation. CONCLUSION: Around 17,200 cancer patients of reproductive age should be informed about the fertility preservation options available. Medical professionals have to better integrate in their daily practice fertility preservation.

Cancer care and public health policy evaluations in France: Usefulness of the national cancer cohort.

BACKGROUND: In the context of the national Cancer Plans of France that have changed the healthcare landscape, it has become necessary to better document and assess the related actions, and to promote research and understanding. The national cancer cohort, an exhaustive population-based cohort, was set up on the basis of the National Health Data System (SNDS) by the French National Cancer Institute. OBJECTIVES: The aim is to describe the French national cancer cohort. METHODS: All people living in France (67 million population) with universal insurance coverage and diagnosed, treated or followed up for a cancer, such as survivors, are included and will be followed up for 25 years. It contains all healthcare consumptions and reimbursements (i.e. hospitalization, outpatient care, medication…) since 2010. Every year, around 650 000 new cases are included. RESULTS: From 2010 to 2015, 6.2 million subjects have been included. Most subjects were entered in 2010, in 2015 it concerned 0.6 million. In 2015, the median age was 65 [54-76]; 51% were women. The primary cancer organ could be attributed with certitude to 87% of the people. The most frequent locations were skin (16%), breast (15%), prostate (12%), colon-rectum (11%) and lung (9%). In 2015, 40% of included subjects underwent surgery for cancer, 16% chemotherapy at hospital and 11% at least one session of radiotherapy. CONCLUSION: Based on SNDS, the cancer cohort has been designed to study cancer care use in the short-, medium- and long-term, and evaluate healthcare and public health policies.

Healthcare expenditure of multiple sclerosis patients in 2013: A nationwide study based on French health administrative databases.

BACKGROUND: Little is known about expenditure items of multiple sclerosis (MS) patients over recent years in France. OBJECTIVE: To describe healthcare expenditure among MS patients and identify the main expenditure drivers. METHODS: All healthcare expenditure reimbursed by French National Health Insurance to MS patients in 2013 was described on the basis of nationwide health administrative databases (SNIIRAM/PMSI). Expenditure was described globally and according to age and sex. RESULTS: The average expenditure among the 90,288 MS patients included was €11,900 per patient. Pharmacy and hospitalisation accounted for 47% and 23% of healthcare expenditure, respectively (38% and 22% of MS patients were treated with disease-modifying therapies and hospitalised overnight or longer, respectively). Average expenditure did not differ according to age. However, pharmacy expenditure decreased with age (from 71% between the ages of 20 and 29 years to 18% between the ages of 70 and 79 years), whereas hospitalisation expenditure increased with age (from 15% to 35%). Paramedical fees accounted for 2% of expenditure between the ages of 20 and 29 years and 24% between the ages of 70 and 79 years. CONCLUSION: Overall, pharmacy expenditure was the main expenditure item, which decreased with increasing age, while hospitalisation and paramedical expenditure increased with increasing age.

French Medico-Administrative Data to Identify the Care Pathways of Women With Breast Cancer.

BACKGROUND: Study of the care pathways is an important topic for care planning, as well as to observe guidelines application. This study aimed to describe care pathways and the period of time between treatments of women with breast cancer (BC), at a population level. MATERIALS AND METHODS: Women with in situ, local and regional BC who were hospitalized and newly treated in 2012 were included and followed for 1 year. Care pathways were described, focusing on surgery (partial mastectomy [PM], total mastectomy [TM]), chemotherapy, and radiotherapy. The periods of time between treatments were measured and compared with the guidelines. RESULTS: The study involved 52,128 women. The most common care pathways among the 2845 women with in situ BC were PM-radiotherapy (46.7%) and TM (28.5%). Among the 41,470 women with local BC, they were: PM-radiotherapy (44.8%) or PM-chemotherapy-radiotherapy (16.0%). The 7813 women with regional BC had similar care pathways, although chemotherapy was given more frequently (73%). The periods of time between surgery and chemotherapy were in accordance with the guidelines for 98% of the women; those between surgery and radiotherapy were affected by adjuvant chemotherapy. Finally, the time between chemotherapy and radiotherapy was longer than recommended for 40% of the women. CONCLUSION: The French medicoadministrative databases allow the study, at a national population level, of the care pathways and periods of time between treatments of women with BC according to the stage of the disease. They were close to the guidelines, although an improvement is highly necessary.

Long-Term Results of a Highly Performing Conformal Electron Therapy Technique for Chest Wall Irradiation After Mastectomy.

PURPOSE: To evaluate locoregional control and survival after mastectomy, as well as toxicity, in patients irradiated by a previously described postmastectomy highly conformal electron beam radiation therapy technique (PMERT). METHODS AND MATERIALS: We included all women irradiated by postmastectomy electron beam radiation therapy for nonmetastatic breast cancer between 2007 and 2011 in our department. Acute and late toxicities were retrospectively assessed using Common Terminology Criteria for Adverse Events version 3.0 criteria. RESULTS: Among the 796 women included, 10.1% were triple-negative, 18.8% HER2-positive, and 24.6% received neoadjuvant chemotherapy (CT). Multifocal lesions were observed in 51.3% of women, and 64.6% had at least 1 involved lymph node (LN). Internal mammary chain, supraclavicular, infraclavicular, and axillary LNs were treated in 85.6%, 88.3%, 77.9%, and 14.9% of cases, respectively. With a median follow-up of 64 months (range, 6-102 months), 5-year locoregional recurrence-free survival and overall survival were 90% (95% confidence interval 88.1%-92.4%) and 90.9% (95% confidence interval 88.9%-93%), respectively. Early skin toxicity was scored as grade 1 in 58.5% of patients, grade 2 in 35.9%, and grade 3 in 4.5%. Concomitant CT was associated with increased grade 3 toxicity (P<.001). At long-term follow-up, 29.8% of patients presented temporary or permanent hyperpigmentation or telangiectasia or fibrosis (grade 1: 23.6%; grade 2: 5.2%; grade 3: 1%), with higher rates among smokers (P=.06); 274 patients (34.4%) underwent breast reconstruction. Only 24 patients (3%) had early esophagitis of grade 1. Only 3 patients developed ischemic heart disease: all had been treated by anthracycline-based CT with or without trastuzumab, all had been irradiated to the left chest wall and LN, and all presented numerous cardiovascular risk factors (2-4 factors). CONCLUSIONS: This study demonstrated the good efficacy of this technique in terms of locoregional control and survival, and good short-term and long-term safety. Longer follow-up is required to analyze chronic cardiac events.

Asthma-Like Symptoms in Homeless Children in the Greater Paris Area in 2013: Prevalence, Associated Factors and Utilization of Healthcare Services in the ENFAMS Survey.

INTRODUCTION: Asthma remains poorly studied in homeless children. We sought to estimate the prevalence of asthma-like symptoms (ALS) and to identify the factors associated with ALS and healthcare service utilisation. MATERIALS AND METHODS: A cross-sectional survey of a random sample of sheltered homeless families was conducted by interviewing 801 parents of children (0-12 years) in 17 languages. ALS were defined as wheezing or night cough without fever during the previous year. Poisson regression models with robust error variance were used to compute prevalence ratios (PR) for factors associated with ALS and healthcare service utilisation for ALS. RESULTS: The prevalence of ALS among the children was 19.9%. Poor housing sanitation was significantly associated with ALS, as being born in the European Union. Most of the children with ALS had used healthcare services (85.4%). The main barriers to accessing such services were having lived in France for less than 49 months, having difficulties in French and living in poor housing conditions. CONCLUSION: ALS prevalence seemed lower than in the general child population, possibly because of the children's origins. Environmental factors associated with ALS point to the need to improve the indoor environment of family shelters. The relatively high rate of healthcare service utilisation should not overshadow existing barriers.

Evaluating Continuity During Transfer to Adult Care: A Systematic Review.

CONTEXT: Appropriate outcomes are required to evaluate transition programs' ability to maintain care continuity during the transfer to adult care of youths with a chronic condition. OBJECTIVE: To identify the outcomes used to measure care continuity during transfer, and to analyze current evidence regarding the efficacy of transition programs. DATA SOURCES: PubMed (1948-2014), Web of Science (1945-2014), Embase (1947-2014), and the reference lists of the studies identified. STUDY SELECTION: Screening on titles and abstracts; full-text assessment by 2 reviewers independently. DATA EXTRACTION: By 2 reviewers independently, by using a Cochrane form adapted to observational studies, including bias assessment. RESULTS: Among the 23 studies retrieved, all but 5 were monocentric, 16 were cohorts (15 retrospective), 6 cross-sectional studies, and 1 randomized trial. The principal disease studied was diabetes (n = 11). We identified 24 indicators relating to 2 main aspects of continuity of care: engagement and retention in adult care. As designed, most studies probably overestimated engagement. A lack of adjustment for confounding factors was the main limitation of the few studies evaluating the efficacy of transition programs. LIMITATIONS: The assessment of bias was challenging, due to the heterogeneity and observational nature of the studies. CONCLUSIONS: This review highlights the paucity of knowledge about the efficacy of transition programs for ensuring care continuity during the transfer from pediatric to adult care. The outcomes identified are relevant and not specific to a disease. However, the prospective follow-up of patients initially recruited in pediatric care should be encouraged to limit an overestimation of care continuity.
