ABSTRACT

BACKGROUND: Multiple myeloma (MM) with the translocation t(11;14) may have inferior outcomes in comparison with other standard-risk MM, and it has been suggested to portend a worse prognosis in African Americans in comparison with Whites. This study used the Center for International Blood and Marrow Transplant Research (CIBMTR) database to examine the impact of t(11;14) on the clinical outcomes of patients with MM of African American and White descent. METHODS: This study evaluated 3538 patients who underwent autologous hematopoietic cell transplantation (autoHCT) for MM from 2008 to 2016 and were reported to the CIBMTR. Patients were analyzed in 4 groups: African Americans with t(11;14) (n = 117), African Americans without t(11;14) (n = 968), Whites with t(11;14) (n = 266), and Whites without t(11;14) (n = 2187). RESULTS: African Americans with t(11;14) were younger, had lower Karnofsky scores, and had more advanced stage MM with a higher Hematopoietic Cell Transplantation-Comorbidity Index (HCT-CI). Fewer African Americans with t(11;14) (21%) had a coexistent high-risk marker in comparison with Whites with t(11;14) (27%). In a multivariate analysis, race and t(11;14) had no association with progression-free survival. However, overall survival was superior among African Americans with t(11;14) in comparison with Whites with t(11;14) (hazard ratio, 0.53; 95% confidence interval, 0.30-0.93; P = .03). Survival was also associated with female sex, stage, time from diagnosis to transplant, a low HCT-CI, and receipt of maintenance. CONCLUSIONS: Race may have a differential impact on the survival of patients with t(11;14) MM who undergo autoHCT and needs to be further studied.

ABSTRACT

Se realizó un estudio prospectivo de 60 pacientes con catarata senil, de los cuales a 30 se les practicó extracción intercapsular de catarata. El grupo control fue sometido a cirugía extracapsular para definir el daño ocasionado al endotelio corneal. En todos los casos se implantó LIO de cámara posterior y se utilizó hialuronato de sodio. El propósito es el de valorar el papel de protección que tiene la técnica intercapsular ya que se supone la cápsula anterior juega un papel protector durante la cirugía de catarata. Al analizar los dos grupos se observó que con la técnica intercapsular la pérdida celular fue de 7 por ciento mientras que aquellos sometidos a extracción extracapsular resultó en 17 por ciento. En ambos existe una pérdida pero la diferencia es estadísticamente significativa (p < 0.05). Tomando en cuenta lo observado, sería de gran utilidad el valorar a largo plazo el comportamiento de la morfología endotelial para analizar la permanencia del daño.
