RESUMEN

Objective: Mammographic screening and management of breast cancer (BC) in elderly women are controversial and continue to be an important health problem. To investigate, through members of the Senologic International Society (SIS), the current global practices in BC in elderly women, highlighting topics of debate and suggesting perspectives. Materials and Methods: The questionnaire was sent to the SIS network and included 55 questions on definitions of an elderly woman, BC epidemiology, screening, clinical and pathological characteristics, therapeutic management in elderly women, onco-geriatric assessment and perspectives. Results: Twenty-eight respondents from 21 countries and six continents, representing a population of 2.86 billion, completed and submitted the survey. Most respondents considered women 70 years and older to be elderly. In most countries, BC was often diagnosed at an advanced stage compared to younger women, and age-related mortality was high. For this reason, participants recommended that personalized screening be continued in elderly women with a long life expectancy.In addition, this survey highlighted that geriatric frailty assessment tools and comprehensive geriatric evaluations needed to be used more and should be developed to avoid undertreatment. Similarly, multidisciplinary meetings dedicated to elderly women with BC should be encouraged to avoid under- and over-treatment and to increase their participation in clinical trials. Conclusion: Due to increased life expectancy, BC in elderly women will become a more important field in public health. Therefore, screening, personalized treatment, and comprehensive geriatric assessment should be the cornerstones of future practice to avoid the current excess of age-related mortality. This survey described, through members of the SIS, a global picture of current international practices in BC in elderly women.

RESUMEN

OBJECTIVE: In early 2020, the spread of coronavirus disease-2019 (COVID-19) led the World Health Organization to declare this disease a pandemic. Initial epidemiological data showed that patients with cancer were at high risk of developing severe forms of COVID-19. National scientific societies published recommendations modifying the patients' breast cancer (BC) management to preserve, in theory, quality oncologic care, avoiding the increased risk of contamination. The Senology International Society (SIS) decided to take an inventory of the actions taken worldwide. This study investigates COVID-19-related changes concerning BC management and analyzes the will to maintain them after the pandemic, evaluating their oncological safety consequences. MATERIALS AND METHODS: SIS network members participated in an online survey using a questionnaire (Microsoft® Forms) from June 15th to July 31st, 2020. RESULTS: Forty-five responses from 24 countries showed that screening programs had been suspended (68%); magnetic resonance imagines were postponed (73%); telemedicine was preferred when possible (71%). Surgeries were postponed: reconstructive (77%), for benign diseases (84%), and in patients with significant comorbidities (66%). Chemotherapy and radiotherapy protocols had been adapted in 28% of patients in both. Exception for telemedicine (34%), these changes in practice should not be continued. CONCLUSION: The SIS survey showed significant changes in BC's diagnosis and treatment during the first wave of the COVID-19 pandemic, but most of these changes should not be maintained. Indeed, women have fewer severe forms of COVID-19 and are less likely to die than men. The risk of dying from COVID-19 is more related to the presence of comorbidities and age than to BC. Stopping screening and delaying treatment leads to more advanced stages of BC. Only women aged over 65 with BC under treatment and comorbidities require adaptation of their cancer management.

RESUMEN

PURPOSE: Diabetes Type I is a chronic disease requiring insulin repeated injections by parenteral during a lifetime. This method of administration as well as traumatic can be a problem for adherence of patients to treatment. In order to overcome these difficulties, we considered the development of therapeutic transdermal drug delivery (TTDD) of insulin. MATERIAL AND METHOD: As active ingredient we used anhydrous human insulin Actarapid HM from Novo Nordisk laboratory, the excipients are ethyl cellulose, Eudragit RS 100 and butylphtalate. We developed two matrix Ethylcellulose/Eudragit in reports 1 and 2, in which are incorporated different proportions of insulin. RESULTS: The study of the release of insulin in phosphate buffer at pH 7.4, showed a continuous release profiles strongly depending on Ethylcellulose/Eudragit report and the initial charge of insulin. CONCLUSION: This study shows that the matrix Ethylcellulose/Eudragit lends itself to the development of a controlled release of insulin. This allows us to continue this work by combining this matrix with other elements for achieving an insulin TTDD.
