Trasplante autólogo de progenitores hematopoyéticos en pacientes con mieloma múltiple
Análisis de factores pronósticos y sobrevida. Experiencia del Hospital Británico
Resumen
Introducción: el trasplante autólogo de progenitores hematopoyéticos (TAPH) es considerado estándar en el tratamiento de primera línea en pacientes con mieloma múltiple (MM) menores de 65 años.
Objetivo:analizar la sobrevida global (SG) y sobrevida libre de eventos (SLEv) de los pacientes con MM trasplantados en el Hospital Británico.
Material y método: se realizó un estudio retrospectivo de los pacientes que recibieron un primer TAPH.
Resultados:entre el 1º de julio de 1999 y el 30 de junio de 2010 se realizaron 56 TAPH a 48 pacientes con MM. Del análisis de los pacientes al primer TAPH, 46% eran mujeres y 54% hombres. La mediana de edad fue de 54 años (32-65 años). El 73% eran IgG, 17% IgA y 10% de cadenas livianas. El 60,4% logró una RC/nRC (RC, RC no confirmada y VGPR) posTAPH. Con una media de seguimiento de 58,6 meses (5,84-186,56), la mediana de SG fue de 121,8 meses (IC 95%: 70,1-173,54 meses). No se hallaron diferencias significativas en SG entre los pacientes que lograron RC/nRC posTAPH y quienes no lo lograron (log Rank p=0,162). La mediana de SLEv fue de 56 meses (IC 95%: 42,2-70,4 meses).
Conclusiones: el TAPH es una herramienta fundamental en el tratamiento de los pacientes con MM y es un procedimiento seguro en la Unidad de Hematología del Hospital Británico.
