the 4 remaining patients were treated with combinations of bortezomib while their condition was evaluated&#46; To include a patient in an HTx waiting list&#44; it is not essential that they undergo prior antineoplastic treatment&#59; however&#44; taking into account the scarcity of organs and the responses that are achieved with combinations of bortezomib&#44; it is worth starting antineoplastic treatment while waiting for an organ or for improvement&#46; The cases we reported on of young patients who did not undergo HTx despite being indicated for the procedure and who improved after treatment with this drug are a good example&#46; Another argument in favor of having patients who are candidates for HTx &#40;or who have already undergone the procedure&#41; undergo antineoplastic treatment is to prevent amyloid redeposition&#44; a condition that we have not observed in any of the cases&#46; There are 2 other facts that should also be considered when deciding to include a patient in an HTx waiting list&#46; First&#44; there are young patients with serious cardiac involvement who die early and who could have benefited from the procedure &#40;4 in our series&#41;&#46; Second&#44; a patient subjected to HTx requires lifelong immunosuppression&#44;

Abstract
Background and objectives

AL amyloidosis is a rare condition whose management is undergoing changes due to recent advances in diagnosis and treatment. We describe a contemporary series of patients with AL amyloidosis to analyze the features that enable early diagnosis and optimal management.

Patients and methods

We recruited for analysis 32 patients (19 women; mean age, 63 years) treated consecutively at our center.

Results

Eighty-four percent of the patients presented with asthenia, dyspnea or edema, with a previous duration of symptoms of 8 months (median). Cardiac (21/32) and renal impairment were the most common type (11/32). All of the patients, except one, had a monoclonal component in serum/urine or abnormal values for free light chains (78%, λ). The bone marrow (BM) showed clonal plasmacytosis in 29 cases. All of the cardiac biopsies and 50% of the BM biopsies showed amyloid deposits. The results of the echocardiogram and/or cardiac resonance were abnormal in 27/30 cases. The median NT-proBNP value at diagnosis was 5200ng/ml. Thirteen patients died due to heart failure, 2 due to rejection after heart transplantation, 2 due to pneumonia and 1 after a stroke. Ten patients did not undergo treatment, 12 were treated with bortezomib and 5 were treated with alkylating agents. Five patients underwent heart transplantation and 4 underwent autologous bone marrow transplantation. Fourteen patients achieved a complete hematologic response and 10 achieved organ response. The median survival was 17 months.

Conclusions

Cardiac involvement is the major determinant of prognosis. Yield of involved organ biopsy is high (100% heart biopsies). Antineoplastic treatment with bortezomib and/or autologous bone marrow transplantation achieves hematological responses with improvements in organ impairment.

Resumen
Antecedentes y objetivo

La amiloidosis AL es una entidad rara cuyo manejo está cambiando gracias a avances recientes en el diagnóstico y tratamiento. Describimos una serie contemporánea de enfermos con amiloidosis AL, para analizar aspectos que permiten un diagnóstico precoz y un manejo óptimo.

Pacientes y métodos

Hemos reunido para su análisis 32 pacientes (19 mujeres, edad mediana 63 años) atendidos consecutivamente en nuestro centro.

Resultados

El 84% de los enfermos comenzaron con astenia, disnea o edemas con una duración previa de los síntomas de 8 meses (mediana). La afectación cardiaca (21/32) y la renal fueron las más frecuentes (11/32). Todos los enfermos, excepto uno, presentaban componente monoclonal en suero/orina o valores anormales de cadenas ligeras libres (78%, λ). La médula ósea (MO) mostraba plasmocitosis clonal en 29 casos. El 100% de las biopsias cardiacas y el 50% de las de MO mostraron amiloide. El ecocardiograma y/o la resonancia cardiaca fueron anormales en 27/30 casos. La mediana de NT-proBNP al diagnóstico fue de 5200ng/mL. Trece enfermos fallecieron por insuficiencia cardiaca, 2 por rechazo tras trasplante cardiaco, 2 por neumonía y uno tras ictus. Diez enfermos no recibieron tratamiento; 12 recibieron bortezomib y 5 alquilantes. Cinco enfermos recibieron un trasplante cardiaco y 4, un autotrasplante de MO. Catorce enfermos alcanzaron respuesta hematológica completa y 10, respuesta de órganos. La supervivencia mediana fue de 17 meses.

Conclusiones

La afectación cardiaca es el principal determinante pronóstico. La rentabilidad de las biopsias de órganos afectados es alta (100% biopsias cardiacas). El tratamiento antineoplásico con bortezomib y/o autotrasplante de MO consigue respuestas hematológicas con mejoría de la afectación de órganos.
