Ten year overall survival of children and adolescents with Hodgkin
lymphoma and HIV in South Africa
Abstract
Background and objectives: Children with Hodgkin lymphoma (HL) and Human
Immunodeficiency Virus (HIV) have low 5 year overall survival rates in
South Africa, home to the world’s largest HIV population. We aimed to
explore factors impacting on survival in children with HIV and HL by
comparing those with and without HIV, and to determine long term
survival. Methods: A retrospective study was conducted to determine
survival rates and prognostic factors in South African children and
adolescents with HL. Univariate risk factor analysis was performed to
analyse prognostic factors. Results: Between January 2000 and December
2010, 271 children and adolescents with HL were eligible for analysis.
Compared to the 242 HIV-uninfected patients, the 29 HIV-infected
patients were younger (median 7.2 vs 10.0 years, p=0.052) and more
likely to present with Stage IV disease (p=0.000) The 5-year overall
survival rate (OS) of HIV-infected patients of 49% versus 84% for
HIV-uninfected patients (p=0.001) appeared to be associated with
hypoalbuminaemia (<20g/dL) and a CD4 percentage of
<15%. Causes of death in the HIV-infected group included
disease progression (6/14), infection (4/14), unknown (3/14) and second
malignancy (1/14). The 10-year OS was 45% in the HIV-infected cohort
and 79% in the HIV-uninfected cohort (p=0.000). Conclusion:
HIV-infected children with HL experience increased mortality due to
opportunistic and nosocomial infections. Particular attention should be
paid to children and adolescents with hypoalbuminaemia and low CD4
percentages at diagnosis to lower treatment-related mortality.
Aggressive supportive care of children with HIV and HL may improve
survival.
