| Abstract: |
The standard approach to treatment of primary refractory/first relapse of classical Hodgkin lymphoma (cHL) is administration of second-line therapy (SLT) followed by consolidation with high-dose therapy and autologous hematopoietic cell transplantation (HDT/AHCT). Historically, this approach cured about 50% of patients. Due to improvements in supportive care, positron emission tomography-adaptive strategies, and incorporation of novel agents into SLT, contemporary studies show that about 75% of patients with primary refractory or first relapse of cHL can be cured. Recent studies evaluating incorporation of PD-1 blockade in SLT appear to show even further improvement in remission rates and bring into question whether an aggressive approach that includes HDT/AHCT is needed for everyone. To address this question, several ongoing studies are beginning to explore the possibility of avoiding or delaying HDT/AHCT for patients with primary refractory or first relapse of cHL.
