RESUMEN

Objetivo. Estimar el efecto del tiempo de atención sobre la supervivencia de mujeres con cáncer de mama. Material y métodos. Se realizó el análisis retrospectivo de 854 mujeres atendidas en 11 hospitales entre 2007 y 2009. Se emplearon estimadores de Kaplan-Meier y un modelo de riesgos proporcionales de Cox. Resultados. 10.5% se diagnosticó en etapa I, mientras que 82.1% demoró más de 67 días entre la percepción de un síntoma y el inicio del tratamiento. La mediana del tiempo desde la entrega de los resultados de la mastografía hasta la biopsia fue de 31 días (RIQ 14-56); en comparación con quienes se encontraron en el cuartil 1 (Q1), la supervivencia fue menor en aquellas que se encontraron en los Q3 y Q4 (HR=1.68, IC95% 0.94-3.00; HR=1.76, IC95% 1.04-2.98, respectivamente). Conclusiones. Se sugiere reducir el tiempo desde la entrega de los resultados de la mastografía a la biopsia diagnóstica para incrementar la supervivencia.
