Perspectives on the Governance of Entitlements to Benefits in the Case of Genetic (Breast Cancer) Risks.","authors":"Friedhelm Meier,&nbsp;Anke Harney,&nbsp;Kerstin Rhiem,&nbsp;Silke Neusser,&nbsp;Anja Neumann,&nbsp;Matthias Braun,&nbsp;Jürgen Wasem,&nbsp;Stefan Huster,&nbsp;Peter Dabrock,&nbsp;Rita Katharina Schmutzler","doi":"10.1007/978-3-030-63749-1_5","DOIUrl":"https://doi.org/10.1007/978-3-030-63749-1_5","url":null,"abstract":"<p><p>This article is a revised version of our proposal for the establishment of the legal concept of risk-adjusted prevention in the German healthcare system to regulate access to risk-reduction measures for persons at high and moderate genetic cancer risk (Meier et al. Risikoadaptierte Prävention'. Governance Perspective für Leistungsansprüche bei genetischen (Brustkrebs-)Risiken, Springer, Wiesbaden, 2018). The German context specifics are summarized to enable the source text to be used for other country-specific healthcare systems. Establishing such a legal concept is relevant to all universal and free healthcare systems similar to Germany's. Disease risks can be determined with increasing precision using bioinformatics and biostatistical innovations ('big data'), due to the identification of pathogenic germ line mutations in cancer risk genes as well as non-genetic factors and their interactions. These new technologies open up opportunities to adapt therapeutic and preventive measures to the individual risk profile of complex diseases in a way that was previously unknown, enabling not only adequate treatment but in the best case, prevention. Access to risk-reduction measures for carriers of genetic risks is generally not regulated in healthcare systems that guarantee universal and equal access to healthcare benefits. In many countries, including Austria, Denmark, the UK and the US, entitlement to benefits is essentially linked to the treatment of already manifest disease. Issues around claiming benefits for prophylactic measures involve not only evaluation of clinical options (genetic diagnostics, chemoprevention, risk-reduction surgery), but the financial cost and-from a social ethics perspective-the relationship between them. Section 1 of this chapter uses the specific example of hereditary breast cancer to show why from a medical, social-legal, health-economic and socio-ethical perspective, regulated entitlement to benefits is necessary for persons at high and moderate risk of cancer. Section 2 discusses the medical needs of persons with genetic cancer risks and goes on to develop the healthy sick model which is able to integrate the problems of the different disciplines into one scheme and to establish criteria for the legal acknowledgement of persons at high and moderate (breast cancer) risks. In the German context, the social-legal categories of classical therapeutic medicine do not adequately represent preventive measures as a regular service within the healthcare system. We propose risk-adjusted prevention as a new legal concept based on the heuristic healthy sick model. This category can serve as a legal framework for social law regulation in the case of persons with genetic cancer risks. Risk-adjusted prevention can be established in principle in any healthcare system. Criteria are also developed in relation to risk collectives and allocation (Sects. 3, 4, 5).</p>","PeriodicalId":39880,"journal":{"name":"Recent Results in Cancer Research","volume":"218 ","pages":"47-66"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39005907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These pathways are critical for the productive replication of high-risk HPVs, and understanding how they contribute to the viral life cycle can provide important insights into HPV's role in oncogenesis.

In this chapter, we will begin with an introduction to fundamental principles and frameworks for understanding ethical issues in pediatrics, highlighting the triadic nature of medical decision-making between a physician, the child-patient, and the child's parent as the surrogate decision-maker. We will then delve into further details of how these principles and frameworks shape the care of children with cancer, examining specific ethical challenges commonly encountered by pediatric oncologists. We will traverse this landscape by examining issues involving (a) informed consent; (b) research involving children; (c) end of life; (d) genetic and genomic testing; and (e) professionalism.

No patient with incurable cancer is to be so tortured for months or years that they want only to die and lack the means to do so. Being unable to die can be worse than death, one might say or think. But until we ourselves have crossed that frontier, we do not know this for certain. To die could be worse than not being able to die. One case is difficult to distinguish from the other. But we pretend we can distinguish them if we praise assisted suicide and euthanasia as solutions to a problem that we not only do not solve, but make worse. Do we need assisted suicide in the face of non-dying skills? The author's answer is no: we do not need euthanasia, neither in that nor in any other case. The logic of euthanasia itself decrees that it cannot be restricted to exceptional cases, based as it is on the idea that the patient's autonomy is to be valued more highly than their actual illness. But if autonomy were of absolute value, it could not be limited to cases of severe disease. The reasons which supporters of euthanasia cite for limiting assisted suicide to the most serious cases of illness, therefore, speak against euthanasia in general. Once the first step has been taken, the application can no longer be limited if, on the one hand, the 'autonomous' desire for death is superior to any counter-argument, and on the other hand, no state of illness is conceivable that could call into question the alleged autonomy.</p>","PeriodicalId":39880,"journal":{"name":"Recent Results in Cancer Research","volume":"218 ","pages":"219-232"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39005797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Questions About the Epidemiology of Malignant Tumours.","authors":"Christel Weiss","doi":"10.1007/978-3-030-63749-1_2","DOIUrl":"https://doi.org/10.1007/978-3-030-63749-1_2","url":null,"abstract":"<p><p>Cancer is the second leading cause of death globally. Malignant tumours are responsible for about 9.6 million deaths in 2018 (Ritchie H (2019) How many people in the world die from cancer? https://ourworldindata.org/how-many-people-in-the-world-die-from-cancer ). Worldwide, about 1 in 6 deaths is due to cancer. This confronts researches with the question of their origin and doctors with treatment options. It is common sense that great efforts should be done in order to reduce the number of cancer-specific deaths. In recent years, in lots of countries a variety of cancer screening programs have been developed, investigated and improved. The basic idea of this approach seems to be quite simple: Tumours will be detected at a very early stage when patients do not yet feel clinical symptoms. Thus, using an appropriate therapy, progression of the disease can be prevented and, concerning a whole population, disease-specific mortality should be reduced. Actually, after the introduction of screening programs, an increasing number of new cancer cases can be observed associated with an apparent reduction of the case fatality rate (i.e. the proportion of deaths due to cancer). Partly, the increasing number of cancers may be explained by the fact that people have a higher life expectancy. Under this aspect, the decreased case fatality rate could be considered as a success which may be attributed to screening efforts. However, there is still insufficient evidence affirming benefits of screening programs for crucial outcomes, i.e. all-cause mortality. In this narrative review, the phenomenon that probabilities and risks are rather often interpreted in an inadmissible way will be described. Furthermore, conceptual issues and inconsistencies between evidence and opinion about screening will be explored.</p>","PeriodicalId":39880,"journal":{"name":"Recent Results in Cancer Research","volume":"218 ","pages":"15-29"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39005904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article considers ethical aspects of establishing the case for cancer screening, building a service programme, monitoring its operation, improving its quality and integrating it with medical progress. The value of (first) screening is derived as a function of key parameters: prevalence of the target lesion in the detectable pre-clinical phase, the validity of the test and the respective net utilities or values attributed to four health states-true positives, false positives, false negatives and true negatives. Decision makers as diverse as public regulatory agencies, medical associations, health insurance funds or individual screenees can legitimately come up with different values even when presented with the same evidence base. The main intended benefit of screening is the reduction of cause-specific mortality. All-cause mortality is not measurably affected. Overdiagnosis and false-positive tests with their sequelae are the main harms. Harms and benefits accrue to distinct individuals. Hence the health claim is an invitation to a lottery with benefits for few and harms to many, a violation of the non-maleficence principle. While a public decision maker may still propose a justified screening programme, respect for individual rights and values requires preference-sensitive, autonomy-enhancing educational materials-even at the expense of programme effectiveness.
