Para este trabajo, los investigadores analizaron los datos de 703 mujeres, que fueron diagnosticadas de cáncer de endometrio entre los años 1996 y 1997. Se observó que las mujeres cuyo tratamiento había comenzado más tarde tenían más probabilidades de sobrevivir.
Los autores han señalado, en la revista "British Medical Journal", que esta relación inversa es realmente compleja. "Nuestro estudio sugiere que la enfermedad influye en el retraso y que ello se convierte en un factor de confusión", han asegurado.
Podría ser también que los especialistas, tras el diagnóstico, diferenciasen generalmente entre pacientes de más alto riesgo y de menor riesgo. Estas últimas serían las que comenzarían más tarde el tratamiento.
Con todo, hay ciertos antecedentes. Algunos estudios israelés ya habían revelado que el índice de supervivencia de mujeres con cáncer de endometrio no variaba si el comienzo del tratamiento se retrasaba unos cuatro meses.
