Background: Rare cancers correspond to approximately 200 clinical entities, which can be grouped into 12 families. Updated data are available for childhood and haematological cancers, ie, for only two of the 12 families of rare cancer. We provide incidence and survival for the remaining ten families of rare adult solid cancers (RAC), across 29 EU Member States and over time.

Gender as the "sociocultural role of sex" is underrepresented in colorectal cancer incidence studies, potentially resulting in underestimated risk factors' consequences and inequalities men/women. We aim to explore how literature focusing on differences between men and women in the incidence of colorectal cancer interprets these differences: through sex- or gender-related mechanisms, or both? We conducted a scoping review using PubMed and Google Scholar. We categorized studies based on their definitions of sex and/or gender variables.

Introduction: Comparable indicators on complete cancer prevalence are increasingly needed in Europe to support survivorship care planning. Direct measures can be biased by limited registration time and estimates are needed to recover long term survivors. The completeness index method, based on incidence and survival modelling, is the standard most validated approach.

Introduction: Too few women with invasive breast cancer are informed of the risk of hypofertility after chemotherapy. However, this risk can be prevented by offering gamete preservation by a specialized team. We believe that if more women were informed about gamete preservation, more of them would accept it.

Non-menopausal women with breast cancer treated with chemotherapy are at intermediate risk of post-treatment amenorrhea and decreased fertility. Although they should receive appropriate information, studies until now show that this is inadequate. We investigated the proportion of women who received information about this risk during the pre-treatment consultation, and those who received an oncofertility consultation to preserve their gametes.

Objectives: We studied both the independent and combined effects of the places of biopsy and treatment on the treatment time interval based on a population-based study.

Methods: We analysed the proportion of patients having a treatment time interval higher than the EUSOMA recommendation of 6 weeks, as a function of the number and the type of care centres the patients attended, from a French population-based regional cohort of women treated in 2015 for an incident invasive non-metastatic cancer (n = 505).

Results: About 33% [95% CI: 27; 38] of patients had a treatment time interval higher than 6 weeks.

Objectives: The aim of this study was to identify the socio-professional and behavioral factors influencing decision-making between surgical and non-surgical treatment in Upper AeroDigestive Tract (UADT) oncology among surgeons and oncologists.

Materials And Methods: We conducted a nationwide online survey among surgeons and medical or radiation oncologists treating head and neck cancer patients in France. The questionnaire collected physicians' demographics, type of practice, individual behavioral characteristics (attitudes toward risk and uncertainty) and data on decision-making via clinical case scenarios.

Background: In out-of-hospital cardiac arrest (OHCA), bystander initiated cardiopulmonary resuscitation (CPR) increases the chance of return of spontaneous circulation and survival with a favourable neurological status. Socioeconomic disparities have been highlighted in OHCA field. In areas with the lowest average socioeconomic status, OHCA incidence increased, and bystander CPR decreased.

Objective: Due to their advanced age in average, colon cancer patients are likely to be exposed to comorbidity. However, the influence of comorbidity on patients' care trajectory and survival is largely under-explored. Hence, we investigate the effect of comorbidity on patients care trajectory and survival based on an observational study in "real-life" setting.

Background: Evidences support social inequalities in cancer survival. Studies on hematological malignancies, and more specifically Acute Myeloid Leukemia (AML), are sparser. Our study assessed: 1/ the influence of patients' socioeconomic position on survival, 2/ the role of treatment in this relationship, and 3/ the influence of patients' socioeconomic position on treatment utilization.

Objective: It is often asserted that the crowding phenomenon in emergency departments (ED) can be explained by an increase in visits considered as non-urgent. The aim of our study was to quantify the increase in ED visit rates and to determine whether this increase was explained by non-severe visit types.

Methods: This observational study covers all ED visits between 2002 and 2015 by adult inhabitants of the Midi-Pyrénées region in France.

Background: When studying the influence of socioeconomic position (SEP) on health from data where individual-level SEP measures may be missing, ecological measures of SEP may prove helpful. In this paper, we illustrate the best use of ecological-level measures of SEP to deal with incomplete individual level data. To do this we have taken the example of a study examining the relationship between SEP and breast cancer (BC) stage at diagnosis.

Background: In France, when someone presents with chest pain, it is recommended to call a health emergency number. The patient talks with an emergency doctor at a medical dispatch centre, who decides whether (or not) to send a Mobile Intensive Care Unit (MICU). Patients with an ST-segment elevation myocardial infarction (STEMI) should have an MICU as their first medical contact, to speed up confirmation of diagnosis and enable them to benefit from reperfusion therapy as quickly as possible.

In this study, we investigate in vitro the optical performance of new-design extended depth of focus (EDOF) complementary intraocular lenses (IOLs) (ACTIVE, Cristalens Industrie, France), compared with traditional bifocal ones. Evaluation of their optical quality was achieved by measuring the point spread function at multiple distances (through focus) using an optical bench. In addition, the modulation transfer function through focus was calculated, correlating our results with actual visual outcomes.

Article Synopsis
  • Older patients with a disease called acute myeloid leukemia can be treated in different ways, which include strong chemotherapy, lighter treatments, or just helping care.
  • Doctors' choices on which treatment to use can depend on their behaviors and the patients' needs.
  • A study surveyed doctors to find out how their characteristics influenced their decisions; results showed that some factors, like being unsure or their ability to deal with many patients, affected whether they chose intensive treatment or not.
