Oncofertility counselling in premenopausal women with HER2-positive breast cancer
No full textA complete oncofertility counselling should be offered to all premenopausal patients before the administration of anticancer treatments. This important discussion is a crucial step for allowing them to take fully informed decisions about the proposed therapy and its potential long-Term consequences as well as on their need and interest of accessing the available strategies for ovarian function and/or fertility preservation. In premenopausal women with HER2-positive early breast cancer, limited evidence exists to counsel them about the potential added gonadotoxicity of targeted agents beyond the damage already caused by chemotherapy. In addition, the prognostic role of treatment-induced amenorrhea in this setting was unknown. In our exploratory analysis within the ALTTO (BIG 2-06) trial, we have recently described the rates of treatment-induced amenorrhea after chemotherapy plus trastuzumab and/or lapatinib and the prognostic value of developing this side effect according to the hormone receptor status of their tumours. We observed similar rates of treatment-induced amenorrhea in the four anti-HER2 treatment arms. The lack of an increased rate of treatment-induced amenorrhea in the dual anti-HER2 blockade arm suggests the possible gonadal safety of these agents. In addition, women with HER2-positive/ hormone receptor-positive tumours showed significantly better survival outcomes if they developed treatment-induced amenorrhea, while no difference was observed for those with HER2-positive/hormone receptor-negative disease. Future research efforts are needed to address the gonadotoxicity of the new available targeted agents as well as to elucidate which is the best adjuvant endocrine therapy in premenopausal women with HER2-positive/hormone receptor-positive disease.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Ovarian protection with gonadotropin-releasing hormone agonists during chemotherapy in cancer patients: From biological evidence to clinical application
No full textSurvivorship issues are an area of crucial importance to be addressed as early as possible by all health care providers dealing with cancer patients. In women diagnosed during their reproductive years, the possible occurrence of chemotherapy-induced premature ovarian insufficiency (POI) is of particular concern being associated with important menopause-related symptoms, psychosocial issues as well as infertility. Temporary ovarian suppression by administering a gonadotropin-releasing hormone agonist (GnRHa) during chemotherapy has been studied to reduce the gonadotoxic impact of chemotherapy thus diminishing the chance of developing POI. Despite more than 30 years of research in both preclinical and clinical settings, the performance of this strategy has remained highly debated until recently. In particular, the potential mechanisms of action for the protective effects of GnRHa during chemotherapy are still not clearly identified. Nevertheless, important novel research efforts in the field have better elucidated the role of this option that is now endorsed for clinical use by several guidelines. This manuscript aims at providing an extensive overview of the literature on the use of temporary ovarian suppression with GnRHa during chemotherapy in cancer patients by addressing its biological rationale, the available preclinical and clinical evidence as well as the still existing grey zones in this field that future research efforts should address.SCOPUS: re.jinfo:eu-repo/semantics/publishe
Viable Options for Fertility Preservation in Breast Cancer Patients: A Focus on Latin America
No full textThanks to the improved survival outcomes observed in recent years, a growing attention has been given to the quality of life issues faced by young women with breast cancer such as fertility preservation and concerns related to future pregnancies. However, several challenges remain for young women with breast cancer considering undergoing fertility preservation strategies. Further specific issues on this regard should be taken into account in Latin America, where patients and physicians face particular barriers that hinder the routine adoption of this practice. Hence, further efforts are needed to overcome these deficiencies and improve the correct referral of breast cancer patients to fertility preservation strategies. The aim of the present review is to focus on the risk of anticancer treatment-related premature ovarian failure and infertility in young breast cancer patients, to summarize the current knowledge on the available options for fertility preservation, and to discuss the safety issues of pregnancy in breast cancer survivors. Furthermore, this review aims to highlight the specific clinical challenges in this field encountered by healthcare providers and young breast cancer patients from Latin American countries

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
