Resumen
Objetivos
Valoración de la utilidad de los programas de cribado en la disminución de la mortalidad por cáncer de mama en estadio I.
Material y métodosEstudio retrospectivo de 314 mujeres con cáncer de mama en estadio I separadas según el método de detección (lesiones diagnosticadas por palpación frente a lesiones diagnosticadas por mamografía). Estudio estadístico comparando la edad, el tamaño tumoral, la anatomía patológica, el grado de diferenciación, el tratamiento, la recurrencia y la supervivencia.
ResultadosNo encontramos diferencias estadísticamente significativas entre ambos grupos en ninguno de los factores analizados, excepto en la supervivencia, que fue mejor en el grupo de lesiones palpables (54,904 frente a 53,170 meses para las lesiones palpables).
DiscusiónEl principal factor pronóstico es el tamaño tumoral al diagnóstico, independientemente del método diagnóstico.

Abstract
Objectives
To evaluate the utility of screening programs in decreasing mortality from stage I breast cancer.
Material and methodsWe performed a retrospective study of 314 women with stage I breast cancer, divided in two groups by diagnostic method (palpable vs. mammographically detected lesions). Statistical analysis was performed comparing age, tumor size, histopathology, histological grade, treatment, recurrence, and survival.
ResultsNo significant statistical differences were found between the two groups, except in survival, which was better in the group with palpable lesions (54.904 vs. 53.170 months).
DiscussionThe main prognostic factor is tumor size at diagnosis, irrespective of the diagnostic method.
Key Words:
