RESUMO
The objective of this study was to evaluate the effect of tamoxifen on the plasma concentration of NT-pro-B-type natriuretic peptide (NT-proBNP) in women undergoing chemotherapy for breast cancer and to correlate changes in NT-proBNP with the left ventricular ejection fraction (LVEF). Over a period of 12 months, we followed 60 women with a diagnosis of breast cancer. The patients were separated into a group that received only chemotherapy (n=23), a group that received chemotherapy + tamoxifen (n=21), and a group that received only tamoxifen (n=16). Plasma levels of NT-proBNP were assessed at 0 (T0), 6 (T6), and 12 (T12) months of treatment, and echocardiography data were assessed at T0 and T12. Plasma NT-proBNP levels were increased in the chemotherapy-only group at T6 and T12, whereas elevated NT-proBNP levels were only found at T6 in the chemotherapy + tamoxifen group. At T12, the chemotherapy + tamoxifen group exhibited a significant reduction in the peptide to levels similar to the group that received tamoxifen alone. The chemotherapy-only group exhibited a significant decrease in LVEF at T12, whereas the chemotherapy + tamoxifen and tamoxifen-only groups maintained levels similar to those at the beginning of treatment. Treatment with tamoxifen for 6 months after chemotherapy significantly reduced the plasma levels of NT-proBNP and did not change LVEF in women with breast cancer.

Morbidity due to cervical and breast cancer in Brazilian woman is high, despite the fact that these pathologies are preventable when detected early. The coverage of public health in this disease is unsatisfactory specially if one takes into account the fact that the techniques used for early detection and prevention of those types of cancer are simple and inexpensive. We observed that not many activities have been developed aiming at the education of women with regard to self-knowledge of their bodies. As a result, we prepared in 1993 a workshop entitled "Woman, a trip through her body" comprising 6 group dynamics where there is an intense participation of every woman as it is a very exciting process. The workshop is carried on by one member of the faculty staff, three nurses and nursing students of Federal University of Espírito Santo. There are 30 participants per workshop each one receiving a name tag. This workshop is composed of the following group dynamics which are developed in a cosy and informal atmosphere: Dynamic 1-Pocket History; Dynamic 2-Hands Touch; Dynamic 3-Drawing/ Modelling; Dynamic 4-Trip through the Body; Dynamic 5-Self-examination; Dynamic 6-Body Feeling.
