Resumen

SILVERA ARENAS, Luz Alba et al. Analysis of the immunohistopathological factors (hormonal receptors, estrogen, progesterone and ERB-2) associated to the prognosis of breast cancer in the population from Barranquilla (2004- 2005). Salud, Barranquilla [online]. 2007, vol.23, n.2, pp.150-161. ISSN 0120-5552.

Objectives: To study the patterns of expression of the estrogen, progestagens and erb-2 receptors in 85 patients attended in two pathology laboratories from Barranquilla, from July 2004 to December 2005. Material and methods: This is a descriptive study of cohort. 104 cases were reviewed and 18 were excluded by lack of data. Inmunohistochemistry studies with techniques of peroxidase - antiperoxidase were made, for which Dako monoclonals antibodies against estrogens, progestagens and ebr-2 were used. Results: Four neoplasias were classified as carcinoma in situ, one mesenquimal cancer, one lobulillar carcinoma and the others were infiltrating ductal carcinomas grade I, II and III. The immunohistochemistry studies showed positivity for estrogens and progestagen at the intracellular level in 73 cases and negativity to erb-2, 11 were negative for both estrogen and progestagen and one was positive to ebr-2. Conclusions:1.The infiltrating ductal carcinoma grades II and III were the histological presentation that appears most frequently (80) cases. 2. 88.03 % of the cases were positive for estrogens and progestagens. 3. The relation between the histological component and the hormonal receptors positivity, suggests a good prognosis.
