  • Zusammenfassung: <jats:title>Abstract</jats:title> <jats:p>Introduction: Age at diagnosis is of prognostic value in Hodgkin's lymphoma (HL) patients. However, there is paucity of data on the impact of age on outcomes of autologous hematopoietic transplantation (auto-HCT) for patients with relapsed and refractory HL.

Baseline patient and disease characteristics were collected. As HL has bimodal peak incidence betweenages of 15 and 34 years and over age of 50 to 55 years, we stratified patients into 3 groups: &gt; 55, 26 to 55 years, and ≤ 25 year age groups. We compared overall survival (OS), progression free survival (PFS), relapse rate and rates of secondary malignancies between these groups. As the outcomes were similar between ≤ 25 and 26 to 55 years groups, subsequent analysis of these two groups was done together as ≤ 55 years vs. &gt; 55 years groups. Baseline patient and disease-related characteristics were compared using the chi-square test for categorical variables and Mann Whitney's rank-sum test for continuous variables.

Prognostic factors for OS, disease progression and non-relapse mortality (NRM) were assessed on univariate and multivariate analyses using Cox proportional hazards regression analysis.</jats:p> <jats:p>Results: 30 (9.7%) patients were &gt; 55, 168 (54.1%) patients were between 26 to 55, and 112 (36.1%) were ≤ 25 years of age. At a median follow-up of 80 months, patients &gt; 55 were at significantly higher risk for mortality with hazard ratio (HR) of 2.3 (95% CI, 1.3-4.2; P = 0.007) compared to patients ≤25 years of age. There was no difference in mortality when between age 26 to 55 years and ≤ 25 years group (HR 1.0; 95% CI, 0.6-1.6; P = 0.9). Risk for progression was similar between the 3 groups, with HRs of 1.3 (95% CI, 0.7-1.5; P = 0.5) and 1.2 (95% CI, 0.8-1.8; P = 0.3) for &gt; 55 group and 26 to 55 groups, respectively compared to ≤ 25 years group (Table 1).
