Abstract

PURPOSE: Optimal management of patients with intermediate-risk lymphocyte-predominant Hodgkin lymphoma (LPHL) is unclear due to their small numbers in most clinical trials. Children's Oncology Group AHOD0031, a randomized phase III trial of pediatric patients with intermediate-risk Hodgkin lymphoma (HL), included patients with LPHL. We report the outcomes of these patients and present directions for future therapeutic strategies.

PROCEDURE: Patients received two cycles of doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide (ABVE-PC) followed by response evaluation. Slow early responders were randomized to two additional ABVE-PC cycles ± two dexamethasone, etoposide, cisplatin, and cytarabine cycles and all received involved field radiotherapy (IFRT). Rapid early responders (RERs) received two additional ABVE-PC cycles. RERs with complete response (CR) were randomized to IFRT or no further therapy. RERs without CR received IFRT.

RESULTS: Ninety-six (5.6%) of 1711 patients on AHOD0031 had LPHL. Patients with LPHL were more likely to achieve RER (93.6% vs. 81.0%; P = 0.002) and CR (74.2% vs. 49.3%; P = 0.000005) following chemotherapy compared with patients with classical HL. Five-year event-free survival (EFS) was superior in patients with LPHL (92.2%) versus classical HL (83.5%) (P = 0.04), without difference in overall survival (OS). Among RERs with CR following chemotherapy (n = 33), there was no difference in EFS or OS between those randomized to receive or not receive IFRT.

CONCLUSION: Children and adolescents with intermediate-risk LPHL represent ideal candidates for response-adapted therapy based on their favorable outcomes. The majority of patients treated with the ABVE-PC backbone achieve RER with CR status and can be treated successfully without IFRT.
