RESUMEN
Objetivo. Se presenta una breve muestra epidemiológica con el objeto de determinar la frecuencia de metástasis óseas del cáncer de mama, que es uno de los tumores malignos más frecuentes en la mujer, que en su evolución tardía produce siembras esqueléticas. Material y métodos. Se recibieron 206 casos de pacientes del sexo femenino con carcinoma mamario entre octubre de 1998 y octubre de 2000, cuyos registros se examinaron en búsqueda de metástasis óseas. Resultados. Se encontró que 45 de los 206 casos (22%) tuvo metástasis en hueso. Los segmentos afectados con mayor frecuencia fueron los siguientes: costillas en 34, columna lumbar en 22, cráneo en 18, columna dorsal y cresta iliaca en 15 de cada una, y finalmente la cadera junto con el fémur proximal en 21. Conclusión. Se considera que el número de tumores metastásicos del esqueleto es notoriamente mayor que el de tumores malignos primarios del mismo y la sobrevida cuando hay metástasis también varía mucho. La supervivencia en el caso del cáncer de mama metastásico es mayor que en el del cáncer pulmonar.
