    Abstract Objective: To evaluate the impact of catch-up human papillomavirus (HPV) vaccination on conization rates in France in a large population-based study.
    Methods: We conducted a retrospective real-life cohort study on data collected prospectively by French National Health Insurance. Echantillon généralistes des bénéficiaires (EGB) is a database composed of demographic and health care utilization data for a 1/97th sample of the French population. We extracted data about all women born between 1983 and 1991, corresponding to the catch-up population (vaccination after 14 years old) at the time of implementation of HPV vaccination. The primary outcome was the occurrence of conization (all types of procedures) compared between vaccinated and non-vaccinated women.
    Results: The cohort consisted of 42,452 women. Vaccination coverage (at least one dose) was low (9.8%, n = 4,129), but increased with time from vaccine implementation, from 0% in the 1983 cohort to 31% in the 1991 cohort. The conization rate was 1% for the overall population. The risk of conization for women between the ages of 19 and 30 years was reduced in the vaccinated group with a Hazard Ratio (HR) of 0.59 (95% CI[0.39-0.90]; p = 0.043).
    Conclusions: With a 10-year follow-up, catch-up HPV vaccination is associated with risk reduction of conization between the ages of 19 and 30.

    Title translation Hot flushes and breast cancer with positive hormone receptors: Mechanisms and management.
    Abstract Breast cancer is the most frequently diagnosed cancer in women and the first cause of cancer death in France. Among the different subtypes of breast cancer, the predominant form is characterized by positive hormone receptors (more than 70% of breast cancers). Hormone therapy thus plays a key role in the strategy of management of these cancers both in adjuvant and metastatic situations. The two types of adjuvant hormone therapy used are selective estrogen receptor modulators and aromatase inhibitors. Fulvestrant, an anti-estrogen, is used alone or in combination with other molecules in metastatic situations. Hot flashes are one of the symptoms most frequently reported by patients under hormone therapy. Hormone replacement therapy, which is currently the most effective treatment for hot flashes, is contraindicated in patients with a personal history of breast cancer. Various therapeutic classes of drugs have been tested in this indication but without real efficacy in the various studies carried out to date, and moreover associated with non-negligible side effects. The recent discovery of the implication of the kisspeptin system located at the hypothalamic level in the mechanism of genesis of hot flashes opens the way to possible new symptomatic treatments for hot flashes. Neurokinin 3 receptor antagonists have shown encouraging preliminary results in postmenopausal cancer-free patients and could be considered in patients in hormonal therapy for breast cancer. Broader additional studies are needed to confirm these initial results.

    Title translation Episode-based bundled payment model: evaluation of medical costs for early operable breast cancer.
    Abstract Introduction: Episode-based bundled payment model is actually opposing to fee-for-service model, intending to incentivize coordinated care. The aims of these study were to determine episode-based costs for surgery in early breast cancer patients and to propose a payment model.
    Methods: OPTISOINS01 was a multicenter prospective study including early breast cancer patients from diagnosis to one-year follow up. Direct medical costs, quality and patient reported outcomes were collected.
    Results: Data from 604 patients were analyzed. Episode-based costs for surgery were higher in case of: planned radical surgery (OR=9,47 ; IC95 % [3,49-28,01]; P<0,001), hospitalization during more than one night (OR=6,73; IC95% [2,59-17,46]; P<0,001), home hospitalization (OR=11,07 ; IC95 % [3,01-173][3,01-54][3,01-543][3,01-54,33]; P<0,001) and re-hospitalization (OR=25,71 ; IC95 % [9,24-89,17; P<0,001). The average cost was 5 268 € [2 947-18 461] when a lumpectomy was planned and 7408 € [4 222-22 565] in case of radical mastectomy. Bootstrap method was applied for internal validation of the cost model showing the reliability of the model with an area under the curve of 0,83 (95 % CI [0,80-0,86]). Care quality and patient reported outcomes were not related to the costs.
    Discussion: This is the first report of episode-based costs for breast cancer surgery. An external validation will be necessary to validate our payment model.

    Abstract Objectives: To describe the burden of COVID-19 in Swiss long-term care facilities in 2020, to identify its influencing factors, and to assess vaccination rates among residents and healthcare workers at the end of the vaccine campaign in Switzerland in May 2021.
    Design: Cross-sectional survey.
    Setting and participants: Long-term care facilities from two Swiss cantons (St. Gallen / Eastern Switzerland and Vaud / Western Switzerland).
    Methods: We collected numbers of COVID-19 cases and related deaths and all-cause mortality for 2020, potential risk factors at the institutional level (e.g. size, infection prevention and control measures, and resident characteristics), and vaccination rates among residents and healthcare workers. Univariate and multivariate analyses were used to identify factors associated with resident mortality in 2020.
    Results: We enrolled 59 long-term care facilities with a median of 46 (interquartile range [IQR]: 33-69) occupied beds. In 2020, the median COVID-19 incidence was 40.2 (IQR: 0-108.6) per 100 occupied beds, with higher rates in VD (49.9%) than in SG (32.5%; p = 0.037). Overall, 22.7% of COVID-19 cases died, of which 24.8% were COVID-19-related deaths. In the univariate analysis, higher resident mortality was associated with COVID-19 rates among residents (p < 0.001) and healthcare workers (p = 0.002) and age (p = 0.013). Lower resident mortality was associated with the proportion of single rooms (p = 0.012), isolation of residents with COVID-19 in single rooms (p = 0.003), symptom screening of healthcare workers (p = 0.031), limiting the number of visits per day (p = 0.004), and pre-scheduling visits (p = 0.037). In the multivariate analysis, higher resident mortality was only associated with age (p = 0.03) and the COVID-19 rate among residents (p = 0.013). Among 2936 residents, 2042 (69.9%) received ≥1 dose of the COVID-19 vaccine before 31 May 2021. Vaccine uptake among healthcare workers was 33.8%.
    Conclusion and implications: COVID-19 burden was high but also highly variable in Swiss long-term care facilities. severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among healthcare workers was a modifiable factor associated with increased resident mortality. Symptom screening of healthcare workers appeared to be an effective preventive strategy and should be included in routine infection prevention and control measures. Promoting COVID-19 vaccine uptake among healthcare workers should be a priority in Swiss long-term care facilities.

    Title translation Impact of the COVID-19 pandemic on breast cancer management: Experience of a French Comprehensive Cancer Center.
    Abstract Introduction: The COVID-19 pandemic had a profound impact on health-care systems and reduced access to care. This study assays the mid-term effects of the COVID-19 pandemic on breast cancer management over a 2-year-period in a single French Comprehensive Cancer Center.
    Methods: We performed, in a French comprehensive cancer center, an observational study including all patients with newly diagnosed breast cancer between 2019 and 2021. We collected the number of first consultations for breast cancer, the number of breast and axillary surgeries, pTNM and ypTNM cancer staging, the therapeutic sequence (surgery or neoadjuvant chemotherapy as a primary treatment), patients' age and their place of residence.
    Results: In total, 14,772 patients had a first consultation for breast cancer. Among these 9058 breast and axillary surgeries were performed, 1798 patients had neoadjuvant chemotherapy as a primary treatment. During the first COVID-19 lockdown ( March17, 2020-May 10, 2020), we observed a reduction in the number of first consultations for breast cancer and breast cancer surgeries giving respectively a 42.3% and 27% rate of change. Subsequently, we observed a resumption of consultations and surgeries with a slight increase in early 2021 compared to 2019. In addition, we did not find any difference in terms of therapeutic sequence, pTNM and ypTNM stages, age at diagnosis or place of residence between the reference year 2019 and the years 2020 and 2021.
    Conclusion: Our study shows a decrease in activity during the first lockdown of 2020, then a resumption of activity. These reassuring results only concern patients with breast cancer, and are specific to our institution, whose oncology activity was preserved during the COVID-19 pandemic.
