In a Danish population-based study reported in the Journal of Clinical Oncology, Øvlisen et al found that parenthood rates in younger Hodgkin lymphoma survivors who did not experience early relapse were similar to those in the general population, but that use of assisted reproductive techniques prior to live births was more common among survivors.
As stated by the investigators, “The majority of young adults with Hodgkin lymphoma are cured, but chemotherapy-induced infertility can have profound psychosocial consequences. Providing data on parenthood rates and use of assisted reproductive techniques after contemporary Hodgkin lymphoma treatment is important for patient counseling and survivorship care.”
The study included Danish patients with Hodgkin lymphoma diagnosed from 2000 to 2015 at ages 18 to 40 years who achieved remission after first-line therapy and were alive without relapse 9 months after diagnosis. They were matched for age, sex, and parenthood status to five randomly selected persons from the general population. Parenthood rates were defined as the rate of first live birth per 1,000 person-years, starting from 9 months after Hodgkin lymphoma diagnosis (index date).
A total of 793 Hodgkin lymphoma survivors (434 male, 359 female) and 3,965 matched comparators were included in the analysis.
Median follow-up was 8.7 years. Progression-free survival at 5 years from index date was 90.6% among male survivors and 89.4% among female survivors.
The 10-year cumulative incidence of first live birth was 38.3% vs 39.9% for male survivors vs comparators, and 42.0% vs 43.3% for female survivors vs comparators. Rates per 1,000 person-years were 56.2 vs 57.1 for male survivors vs comparators (P = .871) and 63.8 vs 61.2 for female survivors vs comparators (P = .672).
Treatment with BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) was associated with lower parenthood rates per 1,000 person-years for male survivors (n = 62) vs matched comparators (28.1 vs 60.8, P = .020) but not for female survivors (n = 26; 61.2 vs 62.5, P = .956).
Among survivors with a live birth after the index date, 21.6% of male survivors vs 6.3% of comparators (P < .001) and 13.6% of female survivors vs 5.5% of comparators (P = .001) had first live birth after use of assisted reproductive techniques. Use of assisted reproductive techniques for reduced fertility was more common among male survivors vs comparators (50.0% vs 22.9%, P < .001) but not among female survivors vs comparators (50% vs 50%).
No differences in gestational age, Apgar score, or newborn measurements were observed between births for Hodgkin lymphoma survivors vs comparators.
The investigators concluded, “The parenthood rates for Hodgkin lymphoma survivors who have not experienced relapse were generally similar to the general population. However, assisted reproductive techniques were used more often before the first live birth in Hodgkin lymphoma survivors, which is relevant information when discussing possible long-term side effects and fertility-preserving treatment options.”
