IntroductionThe EMPACOL Project aims to investigate the link between healthcare professionals’ (HCPs) empathy and the results of the curative treatment of non-metastatic colorectal cancer ...(CRC).Methods and analysisEMPACOL will be an observational multicentric prospective longitudinal study. It will cover eight centres comprising patients with non-metastatic CRC, uncomplicated at diagnosis in two French areas covered by a cancer register over a 2-year period. As estimated by the two cancer registries, during the 2-year inclusion period, the number of cases of non-metastatic CRCs was approximately 480. With an estimated participation rate of about 50%, we expect around 250 patients will be included in this study. Based on the curative strategy, patients will be divided into three groups: group 1 (surgery alone), group 2 (surgery and adjuvant chemotherapy) and group 3 (neo-adjuvant therapy, surgery and adjuvant chemotherapy). The relationship between HCPs’ empathy at the time of announcement and at the end of the strategy, quality of life (QoL) 1 year after the end of treatment and oncological outcomes after 5 years will be investigated. HCPs’ empathy and QoL will be assessed using the patient-reported questionnaires, Consultation and Relational Empathy and European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire, respectively. A relationship between HCPs’ empathy and early outcomes, particularly digestive and genitourinary sequelae, will also be studied for each treatment group. Post-treatment complications will be assessed using the Clavien-Dindo classification. Patients’ anxiety and depression will also be assessed using the Hospital Anxiety and Depression Scale questionnaire.Ethics and disseminationThe Institutional Review Board of the University Hospital of Caen and the Ethics Committee (ID RCB: 2022-A00628-35) have approved the study. Patients will be required to provide oral consent for participation. Results of this study will be disseminated by publication in peer-reviewed journals.Trial registration numberNCT05447611.
The incidence and incidence trends of breast cancer according to molecular subtype are unknown at a population level in France. The registry data enables this study and may give this information, ...that is crucial to describe and understand breast cancer epidemiology.
We estimated the incidence rates of breast cancer for each molecular subtype using data from three cancer registries in France for the period from 2007 to 2012. Molecular subtypes were defined with immunohistochemical data. Poisson models were estimated to modelize the course of breast cancer incidence and to test the trends.
The study included 12,040 patients diagnosed between 2007 and 2012 in the three administrative areas covered by the registries. There was no significant trends in the proportion of each molecular subtype year by year. The age distribution of incident cases was different depending on the molecular subtypes (p < 0.001). The course of incidence between 2007 and 2012 was also different depending on molecular subtype according to the multivariate Poisson model (p < 0.001).
The description of incident cases of breast cancer according to molecular subtype at a population level showed differences in trends. The trends in incidence differed according to molecular subtype, and this should improve our understanding of overall changes in incidence. This analysis is important to plan screening and treatment resources at a population level.
Purpose
In an attempt to understand why cervical cancer (CC) survival is decreasing with diagnosis period among older women in France, this study aimed to estimate the effects of main prognostic ...factors on net survival in CC according to age.
Methods
French cancer registries databases were used to retrospectively analyze women diagnosed with CC in 2011–2012. Net survival was estimated with the Pohar-Perme method and prognostic factors (socio-demographic, clinical variables, stage at diagnosis, therapeutic management) were analyzed with Lambert and Royston’s flexible parametric model.
Results
One thousand one hundred fifty three women with CC were identified. 30.4% were < 45, 41.4% 45–64, and 28.3% ≥ 65 years. Older women were diagnosed at a more advanced stage than younger women: 54.8% regional (FIGO IB2-IVA), 33.0% distant (IVB) in women ≥ 65 years vs 33.7% and 8.0%, respectively in women < 45 years. Half of women with regional stage of CC received recommended treatment; this rate decreased with increasing age (< 45: 66.1%, 45–64: 62.7%, ≥ 65: 29.2%). Older age was significantly associated with increased risk of death: hazard ratio 1.89 for age ≥ 65, as were regional stage (2.81), distant stage (15.99), and not receiving recommended treatment (2.26).
Conclusion
Older women with CC diagnosed at advanced stage who do not receive standard of care are at markedly increased risk of death. Special attention to the management of older women is warranted in France, not only to diagnose cancer at an earlier stage (via gynecological follow-up in these menopaused women who remain at risk of CC), but also to ensure they receive standard of care, taking into account their overall state of health.
Although cancer survivors are known to be at greater risk of developing second primary cancer (SPC), SPC incidence estimates in France are thus far lacking. We used a multivariate approach to compute ...these estimates and analyzed the effect of patient characteristics (gender, age at diagnosis, first cancer site, year of diagnosis and follow-up) on SPC risk.
Data from ten French population-based cancer registries were used to establish a cohort of all patients diagnosed with a first cancer between 1989 and 2004 and followed up until December 31, 2007. The person-year approach was used to estimate standardized incidence ratios (SIRs) and excess absolute risks (EARs) of metachronous SPC. Multivariate Poisson regression models were then used to model SIRs and EARs separately by gender, adjusting for age, year of diagnosis, follow-up and first cancer site.
Among the 289,967 followed-up patients with a first primary cancer, 21,226 developed a SPC. The SIR was of 1.36 (95% CI, 1.35-1.38) and the EAR was of 39.4 excess cancers per 10,000 person-years (95% CI, 37.4-41.3). Among male and female patients, multivariate analyses showed that age, year of diagnosis, follow-up and first cancer site were often independently associated with SIRs and EARs. Moreover, the EAR of SPC remained elevated during patient follow-up.
French cancer survivors face a dramatically increased risk of SPC which is probably related to the high rate of tobacco and alcohol consumption in France. Multivariate modeling of SPC risk will facilitate the construction of a tailored prediction tool to optimize SPC prevention and early detection strategies.
Long‐term population‐based survival data detailed by cancer subtype are important to measure the overall outcomes of malignancy managements. We provide net survival estimates at 1, 3, 5 and 10‐year ...postdiagnosis on 37,549 hematological malignancy (HM) patients whose ages were >15 years, diagnosed between 1989 and 2004 and actively followed until 2008 by French population‐based cancer registries. These are, to our knowledge, the first unbiased estimates of 10‐year net survival in HMs detailed by subtypes. HMs were classified according to the International Classification of Diseases‐Oncology 3. Net survival was estimated with the unbiased Pohar‐Perme method. The results are reported by sex and age classes. The changes of these indicators by periods of diagnosis were tabulated and the trends of the net mortality rates over time since diagnosis graphed. In all, 5‐ and 10‐year age‐standardized net survivals after HMs varied widely from 81 and 76% for classical Hodgkin lymphoma (CHL) to 18 and 14% for acute myeloid leukemia (AML). Even in HMs with the most favorable prognoses, the net survival decreased between 5‐ and 10‐year postdiagnosis. Women had better prognoses than men and age at diagnosis was an unfavorable prognostic factor for most HMs. In patients <55 years old, the net mortality rate decreased to null values 5‐year postdiagnosis in AML and 10‐year postdiagnosis in CHL, precursor non‐HL, chronic myelogenous leukemia, diffuse large B‐cell lymphoma and follicular lymphoma. The prognoses improved for various HMs over the study period. The obtained unbiased indicators are important to evaluate national cancer plans.
What's new?
Net survival data allow comparisons of disease‐specific mortality between different countries or time periods. Relative survival estimates, on the other hand, provide biased net survival rates. In this study, the authors used the unbiased Pohar‐Perme estimator to evaluate longer (10‐year) net survival rates of French patients with haematological malignancies (HM) by sex, age classes, and ten major HM subtypes. Because HM subtypes differ widely in clinical presentation, treatment, and prognosis, population‐based survival data detailed by subtype are important for measuring outcomes of HM management, as well as for long‐range healthcare planning.
Background
Small bowel cancer is not a single entity. Population-based studies taking into account histological diversity are scarce. The aim of this study was to report on their trends in incidence ...by histology in France over the past 20 years.
Methods
All patients with a small bowel cancer diagnosed in 15 French administrative areas covered by a registry from the network of French cancer registries (FRANCIM) were included. Age-standardized incidence rates were estimated using the world standard population. Incidence rates were calculated by gender, age group, histology, and 5-year period.
Results
The overall age-standardized incidence rates were 1.46/100,000 inhabitants in men and 0.9/100,000 inhabitants in women. Adenocarcinoma was the most common histological type (38%), followed by neuroendocrine tumors (35%), lymphoma (15%) and sarcoma (12%). Age at diagnosis and tumor location differed between adenocarcinoma and neuroendocrine tumors. The incidence of all four tumor types increased significantly over the 20-year period, with the exception of lymphoma in men. The annual percentage change for neuroendocrine tumors was 3.89% in men and 3.61% in women; for sarcoma, it was 3.38% and 4.08%, respectively. The incidence of adenocarcinoma and lymphoma also increased in women with an annual percentage change of 3.05% and 3.32%, respectively.
Conclusion
Small bowel cancer incidence has increased over time. This increase occurred with different amplitudes and patterns in the four major histological types. The improvement in imaging techniques could partly explain this increase. It is necessary to determine whether predisposing conditions may contribute to this change.
To examine associations between occupational exposure to petroleum-based and oxygenated solvents and the risk of hypopharyngeal and laryngeal cancer.
ICARE is a large, frequency-matched ...population-based case-control study conducted in France. Lifetime occupational history, tobacco smoking and alcohol consumption were collected. Analyses were restricted to men and included 383 cases of hypopharyngeal cancer, 454 cases of laryngeal cancer, and 2780 controls. Job-exposure matrices were used to assess exposure to five petroleum-based solvents (benzene; gasoline; white spirits; diesel, fuels and kerosene; special petroleum products) and to five oxygenated solvents (alcohols; ketones and esters; ethylene glycol; diethyl ether; tetrahydrofuran). Odds ratios (ORs) adjusted for smoking, alcohol drinking and other potential confounders and 95% confidence intervals (CI) were estimated with unconditional logistic models.
No significant association was found between hypopharyngeal or laryngeal cancer risk and exposure to the solvents under study. Non-significantly elevated risks of hypopharyngeal cancer were found in men exposed to high cumulative levels of white spirits (OR = 1.46; 95% CI: 0.88-2.43) and tetrahydrofuran (OR = 2.63; 95CI%: 0.55-12.65), with some indication of a dose-response relationship (p for trend: 0.09 and 0.07 respectively).
This study provides weak evidence for an association between hypopharyngeal cancer and exposure to white spirits and tetrahydrofuran, and overall does not suggest a substantial role of exposure to petroleum-based or oxygenated solvents in hypopharyngeal or laryngeal cancer risk.
IntroductionAt the end of the treatment, many young breast cancer (BC) survivors face difficulties related to fertility and sexuality, mainly due to the side effects of treatment. Integrating patient ...needs into medical decisions is becoming increasingly essential for high quality care. To this end, there is a compelling need to elicit patients’ perspectives through qualitative studies, to understand their experiences and needs in the aftermath of cancer. We aim to: (1) identify clinical, social and economic determinants of sexuality and fertility, and describe other living conditions of young BC survivors in France; and (2) explore young women’s experience after BC in relation to clinical and information needs about fertility preservation and sexual health.Methods and analysisThis is a mixed-methods, cross-sectional, population-based study. In the quantitative component, women diagnosed with non-metastatic BC between 2009 and 2016 and aged 40 years or younger at diagnosis will be identified through the French network of cancer registries (FRANCIM). Participants will complete self-report questionnaires including standardised measures of sexuality, health-related quality of life (HRQoL), anxiety, depression, social deprivation and social support. Fertility and professional reintegration issues will also be assessed. Sexuality profiles will be identified by ascending hierarchical classification and fertility profiles will be identified by latent class models. Determinants of sexuality, fertility and HRQoL will be identified using a mixed regression model. Subsequently, semistructured interviews will be performed with a sample of 30 women who participated in the quantitative study. Interviews will be recorded, transcribed synthetically and content analysis will be performed, with the aid of NVivo software.Ethics and disseminationThis study will be performed in accordance with the declaration of Helsinki. The protocol was approved in October 2020 by the Committee for the Protection of Persons North-West III (20.07.16.44445) and by the French national data protection authority (CNIL-MR003 No1989764-v0).The results of this project will be communicated to the scientific community through publications in international scientific peer-reviewed journals and communications to national and international congresses. Popularised results will also be provided to patient associations. The results of Candy project will also be published on the website of the sponsor, www.cgfl.fr.
Head and neck cancers (HNC) have a poor prognosis and a long treatment delay may have a negative impact on this. Some studies have investigated the determinants of this delay but not in the general ...population and rarely taking into account socio-economic factors. A high-resolution population-based study about cancer management was conducted, using registries in the north-west of France, on HNC diagnosed between 2008 and 2010. The median time between diagnosis and multidisciplinary team meeting (DMI) (
N
= 1631) was 14 days (Q1: 7 to Q3: 26). The median time between diagnosis and first treatment (DTI) (
N
= 1519) was 35 days (Q1: 21 to Q3: 54). When the first treatment was radiotherapy, the interval was 54.5 days (Q1: 40 to Q3: 71). In multivariate analysis, DTI was associated with the type of first treatment and place of treatment. For advanced stage HNC, DTI was associated with comorbidities, topography of the cancer and socio-economic status, underprivileged patients being treated later than privileged ones. Given the French governmental cancer plans which set out to coordinate care pathways via nursing coordinators and to improve the availability of radiotherapy, the waiting times observed in this study still seem long. The optimal care pathway should include adapted social management but the DTI was still longer for underprivileged patients.
Highlights • We quantified the 10-year cumulative risk of second primary cancer. • Depending on first cancer sites, it ranged from 6.2% to 44.0%. • Compared with the general population, it was ...dramatically elevated for tobacco-related cancers. • For head and neck first cancers, the increased risk reached +35.6%. • This could be an argument to convince patients of the value of lifestyle changes.
