Previous issue date: 2017-01-18 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Introduction: Early life stress (ELS) has an important role in the response of psychoneuroimmunoendocrine systems and in the face of a situation as a major life stressor event such as the diagnosis of breast cancer, women with a history of childhood maltreatment may react diferente then others. Objective: To investigate the role of stress before its impact within the systems that regulate biological and psychological responses in the treatment of breast cancer. Method: The empirical study was an exploratory and correlational study with women newly diagnosed with breast cancer, where scales and tests were used for behavioral assessment and verification of the history of child maltreatment, as well as collection of peripheral blood To evaluate the expression of inflammatory markers. This dissertation was also composed by a narrative review, with a hypothesis proposal on the accumulation of stress throughout life and outcomes in the treatment of breast cancer. Results: There were 18 newly diagnosed women with breast cancer, mean age 45.2 (8.3). There were no significant differences between the group of patients and the control group, regarding cognitive scores and depression and anxiety. However, as women with breast cancer who score higher on the child abuse assessment scale had more traumatic symptoms, such as avoidance and hypervigilance. Similarly, women with higher traumatic symptoms had lower rates of inflammatory markers, such as IL-2 and IL-4. Conclusion: Women with a history of childhood maltreatment with more extreme traumatic reactions with respect to the impact of breast cancer discovery, as well as lower expression of inflammatory markers. The construction of the hypothesis was important for the data obtained in empirical research, taking into account the psychological and immunological impact in women with breast cancer who have a history of childhood maltreatment. / Introdu??o: O estresse precoce possui um papel importante na resposta dos sistemas psiconeuroimunoend?crinos e, diante de uma situa??o estressora como o diagn?stico do c?ncer de mama, avalia-se que respostas comportamentais e imunol?gicas diferentes podem ocorrer em mulheres com o diagn?stico de c?ncer de mama com o hist?rico de maus-tratos na inf?ncia. Objetivo: Investigar o papel do estresse precoce e o impacto no mesmo dentro dos sistemas que regulam as respostas biol?gicas e psicol?gicas frente ao tratamento do c?ncer de mama. M?todo: Realizou-se um estudo explorat?rio e correlacional com mulheres rec?m diagnosticadas com c?ncer de mama, onde utilizou-se escalas e testes para avalia??o comportamental e verifica??o de hist?rico de maus-tratos infantis, bem como coleta de sangue perif?rico para avalia??o dos n?veis plasm?ticos de marcadores inflamat?rios. Esta disserta??o tamb?m foi composta de uma revis?o narrativa, com a proposta de uma hip?tese sobre o ac?mulo de estresse ao longo da vida e desfechos no tratamento do c?ncer de mama. Resultados: Avaliou-se 18 mulheres, com m?dia de idade 45.2 (8.3). N?o houve diferen?as significativas entre o grupo de pacientes e grupo controle no que diz respeito a escores cognitivos e de depress?o e ansiedade. Contudo, as mulheres com c?ncer de mama que possu?am maiores escores na escala de avalia??o de maus-tratos infantis apresentaram mais sintomas traum?ticos, como evita??o e hipervigil?ncia. Da mesma forma, mulheres com maiores sintomas traum?ticos apresentaram n?veis plasm?ticos reduzidos de marcadores inflamat?rios, como a IL-2 e IL-4. Conclus?o: Mulheres com hist?rico de maus-tratos infantis possuem rea??es traum?ticas mais extremas no que diz respeito ao impacto da descoberta do diagn?stico do c?ncer de mama, bem como uma redu??o nos n?veis plasm?ticos de marcadores inflamat?rios. A constru??o da hip?tese se mostrou importante para compreender os dados obtidos na pesquisa emp?rica, levando em considera??o o impacto psicol?gico e imunol?gico nas mulheres com c?ncer de mama que possuem o hist?rico de maus-tratos na inf?ncia.
