Mastectomia versus tratamento cirúrgico conservador: impacto na qualidade de vida de mulheres com câncer mamário

OBJECTIVES: to compare the impact of mastectomy and conservative surgery on the quality of life of patients with breast cancer. METHODS: an assessment was made of the quality of life of patients undergoing mastectomy or segmentary mastectomy, at the Pouso Alegre Clinical Hospital, in the Brazilian State of Minas Gerais, using SF-36. The patients were grouped by age (50 years) and years of schooling (8 years). The Mann-Whitney test was used to compare the groups with regard to the age and schooling domains of SF-36. RESULTS: a significant difference between the two groups was found in the domains of physical functioning (p=0.04) and pain (p=0.01): with the patients undergoing a mastectomy registering the worst scores. Young patients who had undergone a mastectomy displayed the worst quality of life in terms of physical functioning (p=0.03), pain (p=0.01) and social functioning (p=0.01); those undergoing conservative surgery aged over 50 years scored worst on role emotional (p=0.05). Patients undergoing a mastectomy with lower levels of schooling scored lower in physical functioning (p=0.01), role physical (p=0.05) and pain (p=0.05). Among those who had attended school for more than eight years, those having undergone a mastectomy scored less in the pain domain (p=0.04). CONCLUSIONS: patients who had undergone a mastectomy had worse results in the physical component of the evaluation of quality of life and this negative impact was more strongly felt among younger patients and those with lower levels of schooling.OBJETIVOS: comparar o impacto da mastectomia e da cirurgia conservadora na qualidade de vida de pacientes com câncer mamário. MÉTODOS: avaliou-se qualidade de vida de pacientes submetidas à mastectomia ou à mastectomia segmentar, no Hospital das Clínicas de Pouso Alegre, Minas Gerais, Brasil, utilizando-se o SF-36. As pacientes foram estratificadas quanto à idade (50 anos) e escolaridade (8 anos). Aplicou-se o teste de Mann-Whitney para comparar os grupos quanto aos domínios do SF-36, idade e escolaridade. RESULTADOS: observou-se diferença significante entre os grupos nos domínios capacidade funcional (p=0,04) e dor (p=0,01): as pacientes mastectomizadas com piores resultados. Pacientes mastectomizadas mais jovens apresentaram pior qualidade de vida em capacidade funcional (p=0,03), dor (p=0,01) e aspectos sociais (p=0,01); as submetidas à cirurgia conservadora, com mais de 50 anos, resultado pior em aspectos emocionais (p=0,05). Pacientes mastectomizadas com menor escolaridade apresentaram escores menores em capacidade funcional (p=0,01), aspectos físicos (p=0,05) e dor (p=0,05). Entre as que frequentaram a escola por mais de oito anos, as mastectomizadas pontuaram menos no domínio dor (p=0,04). CONCLUSÕES: pacientes mastectomizadas apresentaram piores resultados no componente físico da qualidade de vida, e este impacto negativo foi mais acentuado entre pacientes mais jovens e com menor escolaridade.Universidade do Vale do SapucaíUniversidade Federal de São Paulo (UNIFESP)UNIFESPSciEL

Abordagem oncoplástica no tratamento conservador do câncer mamário: análise de custos

PURPOSE: To analyze the direct costs of conservative surgical treatment of breast cancer, performed in a university hospital, to the Brazilian National Health Care Public System (SUS), checking the impact of the oncoplastic approach on these costs. METHODS: One hundred thirty eight breast cancer patients who had undergone conservative treatment with oncoplastic approach (n=36) or not (control group, n=102), in the period from 2005 to 2010, were enrolled. Sociodemographic and clinical data were recorded. The direct costs of the surgical procedure were obtained and analyzed. RESULTS: Groups did not differ in regard to age (p=0.963), and patients in oncoplastic group had a longer time of hospital stay (p=0.000). The median direct cost for the oncoplastic group was R$461.00 and for the control group was R$229.00 (p=0.000). CONCLUSION: The oncoplastic approach has generated higher direct costs in conservative surgical treatment of breast cancer to SUS.OBJETIVO: Analisar os custos diretos do tratamento cirúrgico conservador do câncer mamário, realizado pelo Sistema Único de Saúde (SUS) em um hospital universitário, verificando o impacto da abordagem oncoplástica sobre estes custos. MÉTODOS: Foram incluídas 138 pacientes submetidas ao tratamento conservador do câncer mamário pelo SUS, com abordagem oncoplástica (n=36) ou não (grupo controle, n=102), no período de 2005 a 2010. Foram registrados dados sócio-demográficos e da operação. Os custos diretos do procedimento cirúrgico foram obtidos e analisados. RESULTADOS: Não houve diferença entre os grupos quanto à idade (p=0.963), e o tempo de internação hospitalar foi maior no grupo oncoplástica (p=0,000). A mediana dos custos diretos do grupo oncoplástica foi de R$461,00 e do grupo controle foi de R$229,00 (p=0,000). CONCLUSÃO: A abordagem oncoplástica gerou custos diretos maiores para o tratamento cirúrgico conservador do câncer mamário pelo SUS.UNIVÁS Plastic Surgery DivisionUNIVÁS Mastology DivisionUNIVÁS Hospital das Clínicas Samuel Libânio Plastic Surgery DivisionUNIVÁS School of AdministrationUNIVÁS Bioestatistics DivisionUNIFESP Plastic Surgery DivisionUNIFESP Head of Plastic Surgery DivisionUNIFESP, Plastic Surgery DivisionUNIFESP, Head of Plastic Surgery DivisionSciEL

The aim of this study was to evaluate the immunoexpression of tge MIB1 monoclonal antibody in the normal breast epithelium during the follicular and luteal phases of the ovulatory menstrual cicle

Nosso objetivo foi avaliar a expressao do anticorpo monoclonal MIB1 no epitelio do lobulo mamario normal, em ambas as fases do ciclo menstrual ovulatorio. De vinte e seis mulheres no menacme (15-40 anos), submetidas a exerese de fibroadenomas, foram obtidos fragmentos do tecido adjacente desta lesao. As pacientes eram eumenorreicas e o intervalo entre a ultima gravidez ou uso de hormonios foi de 12 meses. A fase do ciclo foi caracterizada pela ultima menstruacao e pela dosagem serica da progesterona. As pacientes foram distribuidas em dois grupos conforme a fase do ciclo menstrual: GRUPO I, biopsias realizadas entre o 7º e 9º dias (n=12); GRUPO II, biopsias entre o 21º e 24º dias. A cirurgia foi ambulatorial, os tecidos foram fixados em formol a 10% por um periodo maximo de 6 horas e incluidos em parafina. Os cortes com de 3 a 4µ foram processados pela tecnica imunohistoquimica da avidina-biotina-peroxidase, incubados com o anticorpo primario Ki67 (clone MIB1) da Imunotech, na diluicao de 1/30 e strepto ABComplex/HRP duet, Mouse/Rabbit, kit 492 (Dako). As celulas coradas foram contadas, utilizando-se o sistema de analise digital Kontron Imaging System KS 300, em 10 a 15 campos 40X (n=500 celulas), por caso. O teste de MANN-WHITNEY mostrou que a porcentagem de celulas coradas do GRUPO I (media=3,5) foi significativamente menor que do GRUPO II (media=19,6). O estudo mostrou que o anticorpo monoclonal MIB1 se expressa no epitelio do lobulo mamario humano normal, sendo maior na fase luteaBV UNIFESP: Teses e dissertaçõe

Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial

Background: Appropriate dietary recommendations represent a key part of secondary prevention in cardiovascular disease (CVD). We evaluated the effectiveness of the implementation of a nutritional program on quality of diet, cardiovascular events, and death in patients with established CVD. Methods: In this open-label, multicenter trial conducted in 35 sites in Brazil, we randomly assigned (1:1) patients aged 45 years or older to receive either the BALANCE Program (experimental group) or conventional nutrition advice (control group). The BALANCE Program included a unique nutritional education strategy to implement recommendations from guidelines, adapted to the use of affordable and regional foods. Adherence to diet was evaluated by the modified Alternative Healthy Eating Index. The primary end point was a composite of all-cause mortality, cardiovascular death, cardiac arrest, myocardial infarction, stroke, myocardial revascularization, amputation, or hospitalization for unstable angina. Secondary end points included biochemical and anthropometric data, and blood pressure levels. Results: From March 5, 2013, to Abril 7, 2015, a total of 2534 eligible patients were randomly assigned to either the BALANCE Program group (n = 1,266) or the control group (n = 1,268) and were followed up for a median of 3.5 years. In total, 235 (9.3%) participants had been lost to follow-up. After 3 years of follow-up, mean modified Alternative Healthy Eating Index (scale 0-70) was only slightly higher in the BALANCE group versus the control group (26.2 ± 8.4 vs 24.7 ± 8.6, P <.01), mainly due to a 0.5-serving/d greater intake of fruits and of vegetables in the BALANCE group. Primary end point events occurred in 236 participants (18.8%) in the BALANCE group and in 207 participants (16.4%) in the control group (hazard ratio, 1.15; 95% CI 0.95-1.38; P =.15). Secondary end points did not differ between groups after follow-up. Conclusions: The BALANCE Program only slightly improved adherence to a healthy diet in patients with established CVD and had no significant effect on the incidence of cardiovascular events or death. © 2019 The Author
