Utilidad de la biopsia de médula ósea en estadificación de pacientes con cáncer de mama

objective: the objective of the present study is to determine the usefulness and importance of bone marrows biopsy in the breast cancer patients staging. method: to such end, a cross sectional, prospective, and descriptive study was performed. the population was represented by new diagnosed cases of breast cancer view and evaluated in the consult of surgery oncology y mammalian pathology of our institution, formed the sample by 18 cases. the data obtained were processed and classified in an adequate data matrix; the results once separated were analyzed by the simple descriptive statistic technique or percentile simple tabulation, supported by the dispersion measures (the relative frequencies). results: most of the cases were classified in iia and iib clinical stages. all included cases in this research were negative to bone marrow′s micro metastases, and which can predict good prognosis in these patients. at lymph node staging failure as a prognostic factor we can be speculate that the early tumor cell detection can predict the course of the disease better than the staging of axillaries lymph nodes. conclusion: actually the genetic determination has a better impact as a prognostic factor that the conventional staging studies. the determination of bone marrow′s tumor cell can be establish as a very important part of the staging protocol in the different especial oncologic reference centers, and became as same as genetic profile determination in an important prognostic and predictive factor in breast cancer patients at early stages.
