The purpose of this study was to determine whether there is an increased risk of suicide in European Hodgkin Lymphoma (HL) patients compared to the general European population. European HL patients enrolled in the German Hodgkin Study Group (GHSG) HD7 through HD15 studies were analyzed and standardized mortality ratio (SMR) was calculated using suicide mortality rates for the general European population. Case-control analysis was performed to identify characteristics associated with risk of death by suicide. Among 12,202 European HL patients observed for 94,972 person-years, 19 suicides (17 males and 2 females) were identified resulting in a SMR 1.63 (95% CI: 1.01-2.50, p = 0.046). The only characteristic associated with a statistically significant increased risk of suicide was male sex with an odds ratio (OR) 8.42 (95% CI = 1.04-67.85; p = 0.046) on multivariate analysis. These findings were confirmed in an independently analyzed Surveillance, Epidemiology, and End Results Program (SEER) validation dataset. European HL patients have a significantly increased incidence of suicide compared to the general European population. Male HL patients have a greater than 8-fold increased risk of suicide compared to female HL patients. Further study of social risk factors associated with an increased risk of suicide in HL patients is needed., (Copyright © 2019 the Author(s).

The international, randomized phase 3 HD15 trial established 6xeBEACOPP as standard therapy for patients with newly diagnosed advanced-stage Hodgkin lymphoma (HL) within the German Hodgkin Study Group (GHSG). We performed a follow-up analysis to assess long-term efficacy and safety of this approach. Between 2003 and 2008, 2182 patients aged 18 to 60 years were recruited and randomized in a 1:1:1 ratio between 8 or 6 cycles of eBEACOPP or 8 cycles of the dose-dense BEACOPP-14 regimen, each followed by 30 Gy radiotherapy in case of positron emission tomography (PET)-positive residual lesions ≥2.5 cm. The study aimed at demonstrating non-inferiority regarding efficacy of the 2 experimental arms on a significance level of 2.5% each. The intention-to-treat analysis comprised 2126 patients with a median follow-up of 102 months. Ten-year progression-free survival was 81% (97.5% CI 77-85) with 8xeBEACOPP, 84% (80-87) with 6xeBEACOPP, and 84% (80-87) with 8xBEACOPP-14; the non-inferiority margin of 1.51 for the hazard ratio (HR) could be excluded for both comparisons (6xeBEACOPP, HR = 0.7, 97.5% CI 0.5-1.0; 8xBEACOPP-14, HR = 0.9, 97.5% CI 0.7-1.2). Overall survival at 10 years was 88% (85-91), 90% (88-93), and 92% (89-94), respectively. A total of 142 second malignancies corresponding to 10-year cumulative incidences of 10%, 7%, and 7% and standardized incidence ratios of 4.3, 2.5, and 2.8 were reported for 8xeBEACOPP, 6xeBEACOPP, and 8xBEACOPP-14, respectively. This updated analysis of the HD15 trial thus confirms the efficacy and reports on the long-term safety of a shortened first-line chemotherapy consisting of 6xeBEACOPP followed by PET-guided radiotherapy in advanced-stage HL., (Copyright © 2017 the Author(s).
