RESUMO
Li-Fraumeni syndrome (LFS) is a hereditary tumor that exhibits autosomal dominant inheritance. LFS develops in individuals with a pathogenic germline variant of the cancer-suppressor gene, TP53 (individuals with TP53 pathogenic variant). The number of individuals with TP53 pathogenic variant among the general population is said to be 1 in 500 to 20,000. Meanwhile, it is found in 1.6% (median value, range of 0-6.7%) of patients with pediatric cancer and 0.2% of adult patients with cancer. LFS is diagnosed by the presence of germline TP53 pathogenic variants. However, patients can still be diagnosed with LFS even in the absence of a TP53 pathogenic variant if the familial history of cancers fit the classic LFS diagnostic criteria. It is recommended that TP53 genetic testing be promptly performed if LFS is suspected. Chompret criteria are widely used for the TP53 genetic test. However, as there are a certain number of cases of LFS that do not fit the criteria, if LFS is suspected, TP53 genetic testing should be performed regardless of the criteria. The probability of individuals with TP53 pathogenic variant developing cancer in their lifetime (penetrance) is 75% for men and almost 100% for women. The LFS core tumors (breast cancer, osteosarcoma, soft tissue sarcoma, brain tumor, and adrenocortical cancer) constitute the majority of cases; however, various types of cancers, such as hematological malignancy, epithelial cancer, and pediatric cancers, such as neuroblastoma, can also develop. Furthermore, approximately half of the cases develop simultaneous or metachronous multiple cancers. The types of TP53 pathogenic variants and factors that modify the functions of TP53 have an impact on the clinical presentation, although there are currently no definitive findings. There is currently no cancer preventive agent for individuals with TP53 pathogenic variant. Surgical treatments, such as risk-reducing bilateral mastectomy warrant further investigation. Theoretically, exposure to radiation could induce the onset of secondary cancer; therefore, imaging and treatments that use radiation should be avoided as much as possible. As a method to follow-up LFS, routine cancer surveillance comprising whole-body MRI scan, brain MRI scan, breast MRI scan, and abdominal ultrasonography (US) should be performed immediately after the diagnosis. However, the effectiveness of this surveillance is unknown, and there are problems, such as adverse events associated with a high rate of false positives, overdiagnosis, and sedation used during imaging as well as negative psychological impact. The detection rate of cancer through cancer surveillance is extremely high. Many cases are detected at an early stage, and treatments are low intensity; thus, cancer surveillance could contribute to an improvement in QOL, or at least, a reduction in complications associated with treatment. With the widespread use of genomic medicine, the diagnosis of LFS is unavoidable, and a comprehensive medical care system for LFS is necessary. Therefore, clinical trials that verify the feasibility and effectiveness of the program, comprising LFS registry, genetic counseling, and cancer surveillance, need to be prepared.

BACKGROUND: To promote precision oncology in clinical practice, the Japanese Society of Medical Oncology, the Japanese Society of Clinical Oncology, and the Japanese Cancer Association, jointly published "Clinical practice guidance for next-generation sequencing in cancer diagnosis and treatment" in 2017. Since new information on cancer genomic medicine has emerged since the 1st edition of the guidance was released, including reimbursement for NGS-based multiplex gene panel tests in 2019, the guidance revision was made. METHODS: A working group was organized with 33 researchers from cancer genomic medicine designated core hospitals and other academic institutions. For an impartial evaluation of the draft version, eight committee members from each society conducted an external evaluation. Public comments were also made on the draft. The finalized Japanese version was published on the websites of the three societies in March 2020. RESULTS: The revised edition consists of two parts: an explanation of the cancer genomic profiling test (General Discussion) and clinical questions (CQs) that are of concern in clinical practice. Particularly, patient selection should be based on the expectation that the patient's post-test general condition and organ function will be able to tolerate drug therapy, and the optimal timing of test should be considered in consideration of subsequent treatment plans, not limited to treatment lines. CONCLUSION: We expect that the revised version will be used by healthcare professionals and will also need to be continually reviewed in line with future developments in cancer genome medicine.

BACKGROUND: Whether and how to disclose genomic findings obtained in the course of genomic clinical practice and medical research has been a controversial global bioethical issue over the past two decades. Although several recommendations and judgment tools for the disclosure of genomic findings have been proposed, none are sufficiently systematic or inclusive or even consistent with each other. In order to approach the disclosure/non-disclosure practice in an ethical manner, optimal and easy-to-use tools for supporting the judgment of physicians/researchers in genomic medicine are necessary. METHODS: The bioethics literature on this topic was analyzed to parse and deconstruct the somewhat overlapping and therefore ill-defined key concepts of genomic findings, such as incidental, primary, secondary, and other findings. Based on the deconstruction and conceptual analyses of these findings, we then defined key parameters from which to identify the strength of duty to disclose (SDD) for a genomic finding. These analyses were then applied to develop a framework with the SDD matrix and systematic decision-making pathways for the disclosure of genomic findings. RESULTS: The following six major parameters (axes), along with sub-axes, were identified: Axis 1 (settings and institutions where findings emerge); Axis 2 (presence or absence of intention and anticipatability in discovery); Axis 3 (maximal actionability at the time of discovery); Axis 4 (net medical importance); Axis 5 (expertise of treating physician/researcher); and Axis 6 (preferences of individual patients/research subjects for disclosure). For Axes 1 to 4, a colored SDD matrix for genomic findings was developed in which levels of obligation for disclosing a finding can be categorized. For Axes 5 and 6, systematic decision-making pathways were developed via the SDD matrix. CONCLUSION: We analyzed the SDD of genomic findings and developed subsequent systematic decision-making pathways of whether and how to disclose genomic findings to patients/research subjects and their relatives in an ethical manner. Our comprehensive framework may help physicians and researchers in genomic medicine make consistent ethical judgments regarding the disclosure of genomic findings.

Ethical considerations are more stringent in pediatric clinical research than in research targeting adults. However, in Japan, clear guidelines have yet to be presented on the necessary ethical considerations for clinical research involving children. The "Principles of Ethical Consideration Required for Clinical Research Involving Children" provide guiding principles for ethical considerations and the essential ways of thinking that all involved in clinical research on children need to understand in advance.

The Clinical Research Act went into force on April 1, 2018, marking a major shift in clinical research in Japan. Moving forward, review of research plans by a Certified Review Board authorized by the Minister of Health, Labour and Welfare will be necessary when conducting clinical research using pharmaceuticals or medical devices which are off-label or have not been approved, or when conducting clinical research supported by company funding. Moreover, even currently ongoing research will need to be reviewed by a Certified Review Board during the transition period. The main feature of the Clinical Research Act is that only one review by a Certified Review Board will be needed for multicenter studies. That is, ethics review by each participating institution is no longer necessary. While criteria that must be adhered to under the new Act are substantially the same as the rules that have been in place for clinical trials, there are also notable differences, including reporting of adverse events, compensation for health injury, conflict of interest management, and registration in a new clinical trial registry database.

Drug safety issues do not respect national borders. Hence, addressing a safety question may necessitate globally coordinated efforts between regulatory authorities and market authorization holders (MAHs) to draw reliable conclusions. Regulatory authorities have shared responsibility with MAHs sponsoring postmarketing nonintervention studies in determining study goals and design. Their shared accountabilities include what will be investigated and how the data will be retrieved to ensure appropriate study quality required for regulatory decision making. The need for a harmonized framework and ethical standards for postmarketing observational studies is well recognized but has been lacking even among the United States, European Union, and Japan, which are so-called International Conference on Harmonisation (ICH) regions. A recent update of the Council for International Organizations of Medical Sciences International Ethical Guidelines for Health-Related Research Involving Humans provides further clarification on provisions for informed consent and the role of research ethics committees. However, without incorporation into legislative structures, the future impact of these guidelines is uncertain. This lack of harmonization leads to a complex and uncertain framework for ethical review and for participant informed consent, resulting in numerous inefficiencies in the regulatory postmarketing observational studies. The regulatory frameworks for postmarketing observational studies conducted under the auspices of regulatory agencies in the 3 regions are reviewed, with a focus on ethical requirements and opportunities for efficiencies.

BACKGROUND: Amid continuing social unrest from the Great East Japan Earthquake and subsequent Fukushima nuclear accident of 2011, the Japanese government announced plans for a major biobanking project in the disaster-stricken areas, to be administered by the 'Tohoku Medical Megabank Organization' (ToMMo). This project differs from previous biobanking projects in that it 1) was initiated mainly to boost post-disaster recovery and reconstruction; and 2) targets the area's survivors as its primary subjects. Here, we review the ethics of the ToMMo biobanking project within the wider context of disaster remediation. DISCUSSION: Private citizens in the Tohoku region have criticized the project proposal, asking for further review of the ethics of targeting disaster survivors for this study. They claim the project violates the Declaration of Helsinki's ethical provisions in that (1) government and university researchers initiated it without consulting any Tohoku survivors; (2) survivors already suffering extreme losses may view study involvement as meaningless or even undesirable, yet feel forced to participate in exchange for tenuous promises of future assistance, thus exploiting those most in need.Although the ToMMo has promised certain future social benefits for the target population in exchange for participating in its biobanking research, it is questionable whether such research can address the immediate health needs of the Tohoku disaster survivors in any significant fashion. The ethics of recruiting still-struggling survivors is also questionable. SUMMARY: This case analysis demonstrates that conducting a post-disaster biobanking project on survivors poses issues concerning potential exploitation and the just distribution of benefits and burdens. Though the ToMMo emphasizes the project's importance for individual survivors and regional recovery, it is questionable whether such research can justly respond to the survivors' immediate health needs and whether truly voluntary participation can be ensured in such a crisis. Our society must enhance this nationwide debate and reexamine our priorities for recovery in the disaster-stricken regions. We should evaluate both whether and how this project can truly contribute to the survivors' quality of life.

BACKGROUND: To establish appropriate measures that deal with incidental findings (IFs), the neuroscience community needs to address various ethical issues. The current state of research facilities regarding IFs and investigator attitudes as well as potentially eligible research participants must be assessed prior to future discussions and before the development of policies and guidelines. To this end, we conducted two questionnaire surveys to clarify i) how IFs are addressed at neuroimaging research facilities in Japan and ii) the views of investigators and potential research participants regarding the handling of IFs. METHODS: Thirty-one principal investigators (PIs) involved in the Strategic Research Program for Brain Sciences (SRPBS), a government-funded project, were asked to fill out a questionnaire regarding ways IFs were handled at the facility. A total of 110 investigators engaged in SRPBS tasks, including 31 PIs who participated in the research facility survey and researchers conducting studies under the management of the PIs, and 500 individuals from the general public (i.e., general population) were asked to select the most appropriate way to deal with IFs in two scenarios, namely the medical school and humanities and social sciences department scenarios. RESULTS: More than 40% of PIs responded that they did not know or were unsure of what type of approach was employed to handle IFs at their research facilities. Nevertheless, they were willing to improve the current status if sufficient resources were provided. With regard to specialist involvement, 37.7% of investigators responded that it was appropriate to have a specialist check all images in the medical school scenario, whereas 13.3% responded that such involvement was appropriate in the humanities and social sciences department scenario. In contrast, 76.1% and 61.0% of the general population indicated that specialist involvement was appropriate in the medical school and humanities and social sciences department scenarios, respectively. These results show that expectations of the general population exceed those of investigators regarding measures to address IFs. Both investigators and the general population demanded more responsibility from PIs at medical institutions, compared to PIs at non-medical institutions. CONCLUSIONS: Based on our preliminary results, we recommended that a licensed physician perform a screening test to appropriately examine clear abnormalities. These recommendations were implemented by the SRPBS as guidelines for handling IFs in national research projects in Japan.

We outlined five studies regarding the quality of the review by committees based on the Act on the Safety of Regenerative Medicine. The findings raise serious concerns about the independence, integrity, and quality of reviews of therapeutic plans by these committees with inappropriately close relationships to medical institutions and companies.

The use of placebo controls in psychiatric research is controversial. In this article, we focus on a troubling Japanese case of a randomized withdrawal trial of the antidepressant sertraline and analyze the ethical issues underlying it. First, we consider whether a placebo-controlled withdrawal trial should, in general, be considered more ethical than a standard placebo-controlled trial. We argue that the use of a placebo arm in this trial is ethically permissible but that there is no good reason to use a withdrawal trial design. Second, we discuss whether our moral evaluation of the use of placebo in this case should change when the special Japanese regulatory environment is taken into account. We argue that it should not and conclude that the use of withdrawal design in this case is ethically unacceptable.

BACKGROUND: The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) is undertaking a major revision of ICH E6 Good Clinical Practice (GCP) decided to involve external stakeholders in ICH-GCP renovation. Activities such as surveys and public conferences have taken place in the United States, European Union, and Japan. For stakeholder engagement in Japan, a designated research group conducted a survey of academic stakeholders. METHODS: A total of 105 academic stakeholders from 18 institutions responded to the survey. The research group developed recommendations reflecting the survey results and the opinions from patients and the public. RESULTS: The survey showed the top four principles needing renovation were (i) informed consent (Chapter 2.9, 12.4% of respondents believed it needed renovation), (ii) systems for quality assurance (Chapter 2.13, 9.5%), (iii) information on an investigational product (Chapter 2.4, 5.7%), and (iv) procedures on clinical trial information (Chapter 2.10, 5.7%). The top three sections identified as needing renovation were: (i) informed consent (Chapter 4.8, 27.6%), (ii) monitoring (Chapter 5.18, 22.9%), and (iii) composition, functions, and operations of the ethics committee (Chapter 3.2, 14.3%). Recommendations included clarification of ICH-GCP's scope, proportionality in various aspects of clinical trials, diversity and liquidity of ethics committee members, modernization of informed consent procedures, variations in monitoring, and regulatory grade when using real-world data. CONCLUSION: The recommendations from Japanese investigators and patients have been submitted to the ICH E6 Expert Working Group, which will strengthen the robustness of the GCP renovation.

OBJECTIVE: The objective of this study is to assess public attitudes toward pharmaceutical companies' secondary uses of patient records and public preferences regarding consent approaches. METHOD: 3000 responses to an online survey were collected from adults in Japan. The questionnaire included 32 items related to (1) awareness of "clinical trials"; (2) awareness of the processes of drug development, such as cost, time, and the number of candidate substances in a new drug; (3) knowledge of the laws and regulations for use of patient records in Japan; (4) assessment of the public benefit of the secondary use of patient records; (5) preferences for consent for the secondary use of patient records; and (6) basic characteristics of the respondents. RESULTS: The public benefit from secondary use of records by academic institutions for scientific research was rated highest. All of the activities by pharmaceutical companies were rated higher than those by governmental institutions and other for-profit companies. Regarding consent approaches, 37.9% preferred an "opt-in" approach for new drug development by pharmaceutical companies, 79.7% of whom would change their preference to an "opt-out" approach under specific conditions, such as ensuring intended uses only. CONCLUSION: Our respondents consider the "public benefit" as dependent on the relative distance from "promoting public health" when assessing the secondary purpose of patient record use. Pharmaceutical companies should include the beneficial purposes when using patient records with "opt-out" approach. Policy makers should pay more attention to the purposes of use when developing personal information protection policies.

Background: When the suffering of a terminally ill patient is intolerable and refractory, sedatives are sometimes used for symptom relief. Objective: To describe the main principles of revised Japanese clinical guidelines about palliative sedation therapy. Design: Consensus methods using the Delphi technique were used. Results: The main principles of the guidelines that were newly defined or developed are as follows: (1) palliative sedation was defined as "administration of sedatives for the purpose of alleviating refractory suffering" (excluding the aim of reducing patient consciousness); (2) palliative sedation was classified according to the method of administration of sedatives: respite sedation versus continuous sedation (including (continuous) proportional sedation and continuous deep sedation); (3) a description of state-of-the-art recommended treatments for difficult symptoms such as delirium, dyspnea, and pain before the symptom was determined as refractory was included; (4) the principle of proportionality was newly defined from an ethical point of view; and (5) families' consent was regarded as being desirable (mandatory in the previous version). Conclusions: We described the main principles of revised Japanese clinical guidelines about palliative sedation therapy. Further consensus building is necessary.

RESUMO
Under the Japanese drug regulatory system, post-marketing studies (PMS) must be in compliance with Good Post-marketing Study Practice (GPSP). The GPSP Ordinance lacks standards for the ethical conduct of PMSs; although only post-marketing clinical trials are subject to Good Clinical Practice. We conducted a web-based questionnaire survey on the ethical conduct of PMSs in collaboration with the Japanese Society of Hospital Pharmacists and pharmacists belonging to the Society. 1819 hospitals around Japan answered the questionnaire, of which 503 hospitals had conducted company-sponsored PMSs in 2015. 40.2% of the hospitals had obtained informed consent from participating patients in at least one PMS conducted in 2015, the majority of which was in written form. The first and second most frequent reasons for seeking informed consent in PMSs were to meet protocol requirements, followed by the requirement to meet institutional standard operational procedures and the request of the ethical review board of the hospital. Ethical review of PMSs was conducted in 251 hospitals. Despite a lack of standards for informed consent and ethical review in PMSs, a considerable number of study sites employed informed consent and ethical review for PMSs. While company policies and protocols are likely to be major determinants of the ethical conduct of PMSs, the governmental regulatory agency should also play a significant role in implementing a standardized ethical code for the conduct of PMSs.
