Childbirth rates in classical Hodgkin lymphoma (cHL) survivors have historically been reduced compared to the general population. Understanding if contemporary treatment protocols are associated with reduced fertility is crucial as treatment guidelines shift toward more liberal use of intensive chemotherapy. We identified 2834 individuals aged 18-40 years with cHL in Swedish and Danish lymphoma registers, and in the clinical database at Oslo University Hospital diagnosed 1995-2018, who were linked to national medical birth registers. Cox regression adjusted for stage, performance status, year, and age at diagnosis was used to estimate hazard ratios (HRs) and 95% confidence intervals (CI) contrasting time to first childbirth by treatment groups (ABVD, 2-4 BEACOPP, 6-8 BEACOPP) up to 10 years after diagnosis. Overall, 74.8% of patients were treated with ABVD, 3.1% with 2-4 BEACOPP and 11.2% with 6-8 BEACOPP. Adjusted HRs comparing childbirth rates in individuals treated with 6-8 BEACOPP, and 2-4 BEACOPP to ABVD were 0.53 (CI: 0.36-0.77) and 0.33 (CI: 0.12-0.91) for males, and 0.91 (CI: 0.61-1.34) and 0.38 (CI: 0.12-1.21) for females. Cumulative incidence of childbirths after 10 years was 19.8% (CI: 14.5%-27.0%) for males and 34.3% (CI: 25.8%-45.6%) for females treated with 6-8 BEACOPP. Proportions of children born after assisted reproductive technique (ART) treatments were 77.4% (CI: 60.2-88.6%) for males following 6-8 BEACOPP, and <11% for females. Among ABVD treated patients the corresponding proportions were 12.2% (CI: 8.5%-17.3%) and 10.6% (CI: 7.4%-14.9%). BEACOPP treatment is associated with decreased childbirth rates compared to ABVD in male, but not female, cHL patients, despite widespread access to ART in the Nordics.

High-dose prednisolone is used in first-line treatment for lymphoma, but the potential adverse impact on bone health is unclear. Danish patients with diffuse large B-cell lymphoma or follicular lymphoma diagnosed between 2000 and 2012 were matched to the background population. Osteoporotic events (osteoporosis treatment or low-energy fracture) were identified using the Danish National Patient Registry and Prescription Registry. In total, 2589 patients and 12,945 controls were included. Lymphoma patients had increased risk of osteoporotic events compared to the matched population (hazard ratio 1.61 [95% confidence interval 1.40;1.84]). The 5- and 10-year cumulative risks of osteoporotic events for lymphoma patients were 10.0% [8.6;11.4] and 16.3% [13.8;18.7], whereas corresponding risks in the background population were 6.8% [6.3;7.3] and 13.5% [12.4;14.6]. Patients without osteoporotic event in the first two years after treatment were not at higher risk of osteoporotic events in subsequent years. Risk factors for osteoporotic events were female sex and age >70 years.
