[Nutritional status of patients with breast cancer attended in the Mastology Service of Belo Horizonte's Hospital das Clínicas in the state of Minas Gerais, Brazil]. / Avaliação nutricional de pacientes com câncer de mama atendidas no Serviço de Mastologia do Hospital das Clínicas, Belo Horizonte (MG), Brasil.

The scope of this article is to evaluate the nutritional status, body composition and tumor characteristics of 31 patients with breast cancer attended at the Mastology Service of Hospital das Clínicas of the Federal University of Minas Gerais. Dietary data were obtained from the 24-hour dietary recall in the pre-operative state and analyzed by the DietWin Professional 2008 Nutrition Software. Body composition was assessed by bioelectrical impedance analysis. The tumor characterization data were collected from medical records. The mean age of patients was 50.75 ± 14.34 years. Excess body weight was found in 58% and waist circumference greater than 80 cm in 64.5% of patients Excessive consumption of oils and sugars was observed in 90.3% and 83.8%, respectively. Most had low intakes of calcium and vitamins B6, B12 and A. The predominant diagnosis was type II histological grade invasive ductal carcinoma in stage II or III. The prevalence of overweight and inadequate dietary intake demonstrate the need for individualized nutritional guidance and monitoring to improve the prognosis and quality of the life of patients.

O objetivo deste artigo é avaliar o perfil nutricional, a composição corporal e as características tumorais de 31 pacientes com câncer de mama atendidas pelo Serviço de Mastologia do Hospital das Clínicas da Universidade Federal de Minas Gerais. Os dados da dieta foram coletados usando-se o recordatório de 24 horas no momento pré-cirúrgico e analisados pelo Software de Nutrição DietWin Profissional 2008. A composição corporal foi avaliada por análise de impedância bioelétrica. A caracterização tumoral foi realizada através da avaliação dos dados obtidos no prontuário de cada paciente. A idade média foi de 50,75 ± 14,3 anos. Foi observado excesso de peso corporal em 58% das pacientes e circunferência da cintura maior que 80 cm em 64,5%. Consumo excessivo de alimentos pertencentes aos grupos dos óleos e dos açúcares foi verificado em 90,3% e 83,8%, respectivamente. A maioria das pacientes apresentou baixo consumo de cálcio e de vitaminas B6, B12 e A. O diagnóstico predominante foi de carcinoma ductal invasivo, de grau histológico tipo II em estadio II ou III. A prevalência do excesso de peso e a inadequação do consumo alimentar demonstram a necessidade de orientação e acompanhamento nutricional individualizado, visando melhorar o prognóstico e a qualidade de vida da paciente.

Combination therapy with carboplatin and thalidomide suppresses tumor growth and metastasis in 4T1 murine breast cancer model.

Carboplatin, efficient cytostatics for cancer therapy, could induce apoptosis and inhibit the growth of vascular endothelium in several tumor cell lines and xenograft models. It has been suggested that the antitumor effect of chemotherapy could be increased by combining it with an antiangiogenesis agent in anticancer strategy. The present study explored the potential to increase the antitumor effect of carboplatin by combining it with thalidomide in mouse 4T1 breast cancer models, and the underlining mechanism was investigated. The systemic administration of carboplatin and thalidomide significantly decreased tumor growth through increased tumor cell apoptosis compared with either control group. Collectively, these findings suggest that combined treatment has shown synergistic suppression in tumor progression according to the analysis. Furthermore, also was observed reduction in number of lung metastases as compared to isolated treatments and increased survival of the animals. The present study may be important in future exploration of the potential application of the combined approach in the treatment of breast cancer.
