Estudo de genes e variantes genéticas associadas ao câncer de mama familial: impactos no aconselhamento genético / Study of genes and genetic variants associated with familial breast cancer: impacts on genetic counselingCarmo, Gabriel Bandeira do 30 November 2018 (has links)
Dentre todos os tipos de câncer, excluindo-se o câncer de pele do tipo não melanoma, o de mama é o mais frequente em mulheres, sendo a segunda maior causa de morte por neoplasias nesse segmento da população. Em determinadas famílias, a incidência de câncer é superior à esperada para a população em geral, devido principalmente ao compartilhamento de fatores ambientais e/ou mutações genéticas responsáveis por facilitar ou dirigir a oncogênese. Os indivíduos que apresentam câncer de mama e histórico familial dessa patologia são descritos dentro do grupo câncer de mama familial (CMF), responsável por aproximadamente 5 a 10% do total de casos de câncer de mama. Atualmente, pacientes com CMF são frequentemente testados para mutações nos genes BRCA1 e BRCA2. Entretanto, estima-se que as variantes patogênicas presentes nos dois genes são responsáveis por somente 20% dos casos de CMF em que a etiologia genética é conhecida. Com relação aos testes genéticos para predisposição hereditária ao câncer de mama, torna-se relevante, portanto, a reavaliação da constituição dos painéis multigênicos frente ao estado do conhecimento científico atual, contemplando-se as mais recentes atualizações acerca dos genes e variantes genéticas associadas ao CMF. Neste trabalho, realizamos uma revisão bibliográfica que identificou 45 genes com associação estatística ao CMF, dentre eles 16 são frequentemente avaliados em painéis multigênicos brasileiros e internacionais. Em análise in silico, avaliamos as funções celulares e interações entre os produtos gênicos associados à patologia. Nossos resultados sugerem a adição de oito genes à composição de painéis multigênicos realizados no Brasil, EUA e Europa para avaliação da predisposição hereditária ao câncer de mama. Essa análise crítica pode auxiliar o aprimoramento de estratégias de prevenção, triagem, manejo clínico e determinação do risco de ocorrência e recorrência, com impactos sobre o aconselhamento genético (AG) oferecido aos pacientes afetados pelo câncer familial e seus familiares. Complementarmente, avaliamos as variantes gênicas presentes em pacientes com câncer de mama que realizaram o painel multigênico para predisposição hereditária ao câncer no Centro de Pesquisa sobre o Genoma Humano e Células-Tronco (CEGH-CEL). As frequências de mutações da coorte do CEGH-CEL são semelhantes às obtidas em estudos internacionais, possibilitando a utilização de painéis multigênicos com composições similares em populações de diversas localidades / Of all types of cancer, except for non-melanoma skin cancer, breast cancer is the most common among women, and it\'s the second leading cause of death by neoplasia in this segment of the population. In some families, the incidence rates of cancer are higher than expected for the general population because of the environmental factors and/or genetic mutations responsible for facilitating or driving oncogenesis. The individuals who have breast cancer and a family history of this pathology fall into the group of familial breast cancer (FBC), which is responsible for approximately 5-10% of all breast cancer cases. Currently, patients with FBC are frequently tested for mutations in the BRCA1 and BRCA2 genes. It is estimated, however, that the pathogenic variants of these genes account for only 20% of all FBC cases in which the genetic etiology is known. In relationship to the genetic tests for inherited predisposition for breast cancer, therefore it is relevant to reassess the multi-gene panel composition, considering the state of scientific knowledge today, including the most recent research on the genes and its variants associated with FBC. In this paper we did a literature review, which identified 45 genes statistically associated with FBC, out of which 16 are frequently assessed in multi-gene panels in Brazil and abroad. Through in silico analysis we were able to evaluate cell functions and interactions with gene products associated with cancer. Our results suggest the addition of eight genes to the multi-gene panel composition carried out in Brazil, in the USA and in Europe to assess hereditary predisposition to breast cancer. This critical analysis can assist in the development of preventive actions, triage, clinical management and in determining the risk of occurrence and recurrence, which impacts on the genetic counseling (GC) offered to the patients of familial cancer and their relatives. Additionally, we evaluated the genetic variants in patients diagnosed with breast cancer who have undergone multi-gene panel testing for hereditary predisposition to cancer at the Centro de Pesquisa sobre o Genoma Humano e Células-Tronco (CEGH-CEL). These cohort\'s mutation frequencies are similar to the results in international studies, which could enable the use of multi-gene panels with similar compositions in populations from various locations

The Impact of Prophylactic Salpingo-oophorectomy on Health in Women who carry a BRCA1 or BRCA2 MutationFinch, Amy 30 August 2011 (has links)
Prophylactic salpingo-oophorectomy, the preventive removal of the ovaries and fallopian tubes, is recommended to women who carry a BRCA1 or BRCA2 mutation in order to reduce the risk of breast, ovarian and fallopian tube cancer. The short and long term health and quality of life effects of this procedure are not well understood. We examined the actual and perceived reduction in cancer risk associated with this surgery. The impact of prophylactic salpingo-oophorectomy on health-related quality of life, psychological distress, cancer worry, menopausal symptoms, and sexual function during the year following surgery was also evaluated. In our prospective study, prophylactic salpingo-oophorectomy was associated with an 80% reduction in ovarian and fallopian tube cancer risk. The residual risk for primary peritoneal cancer was 0.2% per year or 4.3% at 20 years after salpingo-oophorectomy. Most women accurately perceived their risk of breast cancer. However, the risk for ovarian cancer was overestimated, particularly by women who carry a BRCA2 mutation. Physical and mental health-related quality of life did not decrease in the year following surgery; and psychological distress was similar to levels experienced by the general population. Most women were significantly less worried about cancer after the surgery, however, a subset of women continued to experience significant cancer specific distress after prophylactic salpingo-oophorectomy. Women who underwent prophylactic salpingo-oophorectomy when premenopausal experienced a significant worsening of vasomotor symptoms and a decline in sexual functioning. Hormone replacement therapy mitigated these symptoms, but not to pre-surgical levels. Dyspareunia was somewhat alleviated by hormone replacement therapy, however, the decrease in sexual pleasure was not. Satisfaction with the decision to undergo prophylactic salpingo-oophorectomy was high regardless of these symptoms. These studies will provide women who are considering prophylactic salpingo-oophorectomy with information about the reduction in cancer risk associated with the surgery and the possible effects experienced during the year following surgery.
