Successful Pregnancy and Fetal Outcomes Following Brentuximab Vedotin for Early Relapsed Classic Hodgkin Lymphoma After Autologous Stem Cell Transplant.

ABSTRACT

Brentuximab vedotin (BV), an anti-CD30 antibody with monomethyl auristatin E conjugate, has shown clinical effects against relapsed/refractory classic Hodgkin lymphoma (cHL) and hence is widely used in the clinical setting. We report a special clinical case of successful pregnancy and fetal outcome in a patient with cHL who achieved long-term remission with BV for early relapse after an autologous stem cell transplant (auto-SCT). A 27-year-old woman with advanced cHL achieved complete response (CR) after six cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) regimen. Embryos obtained from intracytoplasmic sperm injection were cryopreserved before the initiation of induction chemotherapy. Despite achieving a second CR following intensive salvage chemotherapy, auto-SCT, and radiotherapy, she relapsed again six months after transplantation. BV monotherapy was administered as salvage therapy. She completed 16 cycles of BV and achieved CR. Six months after BV completion, she expressed her desire to bear a child. She achieved pregnancy through third in vitro fertilization and embryo transfer and delivered a healthy baby. BV may provide a potentially curative treatment for patients with cHL relapsed after auto-SCT. Pregnancy should be avoided during BV administration up to a certain period after the end of administration. Fertility preservation is important for adolescent and young adult cancer survivors, and patients should be informed of cancer-related infertility and fertility preservation options prior to the initiation of cancer treatment.
