RESUMEN

INTRODUCTION: Current guidelines for the treatment of phyllodes tumors recommend wide local excision for all histopathological subtypes. However, it is unknown which subtypes have tendency to recur after marginal or incomplete excision. This may lead to over-treatment by re-excision surgery for tumors with little or no potential to recur. MATERIALS AND METHODS: All patients with benign, borderline or malignant phyllode tumors presenting at our institution between 2000 and 2016 were retrospectively analyzed. RESULTS: A total of 57 patients could be included, of which 39 tumors were benign (60%), three were borderline (5%), and seven were malignant phyllodes tumors (12%). There were also eight phyllodes-like fibroadenomas (14%). Fifty-two patients (91%) underwent local excision as primary treatment, resulting in tumor-positive or close-resection margins in 32 patients (61.5%) of whom five patients (15.6%) had re-excision surgery. During a median follow-up of 5 years, local recurrence occurred in four patients (7.0%) with a median time-to-recurrence of 12 months. Borderline and malignant subtypes were associated with a significantly higher recurrence rate compared to other subtypes (p = 0.039). CONCLUSION: Although an adequate tumor-negative resection margin should be obtained for borderline and malignant phyllodes tumors, this study confirms that wide local excision is the appropriate primary treatment for all histopathological subtypes. However, if tumor-negative margins were not obtained at first excision, a wait-and-see approach is justified for benign phyllodes tumors.

RESUMEN

The BrainNet Europe consortium, which is a consortium of 19 European brain banks, took the initiative to draft a series of documents to provide an ethical framework for brain banks to follow. The framework includes an ethical code of conduct, a model for brain bank regulations, and a toolkit containing several documents. The sources for the information included came from the laws, regulations, and guidelines (declarations, conventions, recommendations, guidelines, and directives) that had been issued by international key organizations, such as the Council of Europe, European Commission, World Medical Association, and World Health Organization. The code of conduct addresses fundamental topics such as the rights of the persons donating their tissue, the obligations of the brain bank with regard to respect and observance of such rights, informed consent, confidentiality, protection of personal data, collections of human biologic material and their management, and transparency and accountability within the organization of a brain bank. The code of conduct was ratified by all European brain banks in 2009. This chapter describes the process of establishing the code of conduct within the BrainNet Europe consortium and elaborates on three key aspects of the code of conduct, namely informed consent, genetics, and financial aspects in brain banking.

RESUMEN

Well-characterized human brain tissue is crucial for scientific breakthroughs in research of the human brain and brain diseases. However, the collection, characterization, management, and accessibility of brain human tissue are rather complex. Well-characterized human brain tissue is often provided from private, sometimes small, brain tissue collections by (neuro)pathologic experts. However, to meet the increasing demand for human brain tissue from the scientific community, many professional brain-banking activities aiming at both neurologic and psychiatric diseases as well as healthy controls are currently being initiated worldwide. Professional biobanks are open-access and in many cases run donor programs. They are therefore costly and need effective business plans to guarantee long-term sustainability. Here we discuss the ethical, legal, managerial, and financial aspects of professional brain banks.

RESUMEN

Research utilizing human tissue and its removal at post-mortem has given rise to many controversies in the media and posed many dilemmas in the fields of law and ethics. The law often lacks clear instructions and unambiguous guidelines. The absence of a harmonized international legislation with regard to post-mortem medical procedures and donation of tissue and organs contributes to the complexity of the issue. Therefore, within the BrainNet Europe (BNE) consortium, a consortium of 19 European brain banks, we drafted an ethical Code of Conduct for brain banking that covers basic legal rules and bioethical principles involved in brain banking. Sources include laws, regulations and guidelines (Declarations, Conventions, Recommendations, Guidelines and Directives) issued by international key organizations, such as the Council of Europe, European Commission, World Medical Association and World Health Organization. The Code of Conduct addresses fundamental topics as the rights of the persons donating their tissue, the obligations of the brain bank with regard to respect and observance of such rights, informed consent, confidentiality, protection of personal data, collections of human biological material and their management, and transparency and accountability within the organization of a brain bank. The Code of Conduct for brain banking is being adopted by the BNE network prior to being enshrined in official legislation for brain banking in Europe and beyond.

RESUMEN

Brain banks are used to gather, store, and provide human brain tissue for research and have been fundamental to improving our knowledge of the brain in health and disease. To maintain this role, the legal and ethical issues relevant to the operations of brain banks need to be more widely understood. In recent years, researchers have reported that shortages of high-quality brain tissue samples from both healthy and diseased people have impaired their efforts. Closer collaborations between brain banks and improved strategies for brain donation programmes will be essential to overcome these problems as the demand for brain tissue increases and new research techniques become more widespread, with the potential for substantial scientific advances in increasingly common neurological disorders.

RESUMEN

In this article case report of urothelial carcinoma implantation in both adnexa is reported, following a perforation of the bladder wall during a transurethral resection of a bladder tumor. The 81-year-old female patient had an extensive history of multiple recurrent non-muscle-invasive urothelial carcinoma of the bladder. Intraperitoneal perforation was detected and managed conservatively. Fifteen months after the procedure, the patient presented at the gynecology department with a mass in the left adnex, which was suspicious for malignancy, for which she subsequently underwent hysterectomy in combination with bilateral resection of the adnexa. Pathology showed papillary urothelial carcinoma in both ovaries. A literature search was performed to present an up-to-date review of the available data on bladder perforations during transurethral resection of the bladder and tumor implantation, its management and oncological outcomes.

RESUMEN

Collections of human postmortem brains gathered in brain banks have underpinned many significant developments in the understanding of central nervous system (CNS) disorders and continue to support current research. Unfortunately, the worldwide decline in postmortem examinations has had an adverse effect on research tissue procurement, particularly from control cases (non-diseased brains). Recruitment to brain donor programmes partially addresses this problem and has been successful for dementing and neurodegenerative conditions. However, the collection of brains from control subjects, particularly from younger individuals, and from CNS disorders of sudden onset, remains a problem. Brain banks need to adopt additional strategies to circumvent such shortages. The establishment of brain bank networks allows data on, and access to, control cases and unusual CNS disorders to be shared, providing a larger resource for potential users. For the brain banks themselves, inclusion in a network fosters the sharing of protocols and development of best practice and quality control. One aspect of this collective experience concerns brain bank management, excellence in which is a prerequisite not only for gaining the trust of potential donors and of society in general, but also for ensuring equitable distribution to researchers of high quality tissue samples. This review addresses the legal, ethical and governance issues, tissue quality, and health and safety aspects of brain bank management and data management in a network, as well as the needs of users, brain bank staffing, donor programs, funding issues and public relations. Recent developments in research methodology present new opportunities for researchers who use brain tissue samples, but will require brain banks to adopt more complex protocols for tissue collection, preparation and storage, with inevitable cost implications for the future.
