Liposomal Doxorubicin, Vinblastine and Dacarbazine Plus Consolidation Radiotherapy of Residual Nodal Masses for Frontline Treatment in Older Adults With Advanced Stage Classic Hodgkin Lymphoma: Improved Outcome in a Multi-Center Real-Life Study

In elderly patients with high-risk classic Hodgkin lymphoma (c-HL), we evaluated the impact of a new modality treatment without bleomycin, that is, liposomal doxorubicin (NPLD)-based regimen plus consolidation radiotherapy of residual nodal masses (RNMs), on overall survival (OS) and progression free survival (PFS). In this retrospective study (2013–2023) conducted in tertiary hospitals in the bay of Naples (Italy), 50 older adults (median age, 69 years; range, 60–89) with advanced stage c-HL received frontline treatment with MVD ± irradiation. MVD consisted of 25 mg/m² of NPLD along with standard Vinblastine and Dacarbazine for a total of 6 cycles (twelve iv administrations, every 2 weeks) followed by radiation of RNMs with size ≥ 2.5 cm at computed tomography. Patients underwent MVD with a median dose intensity of 92%. At 2-deoxy-2[F-18] fluoro-D-glucose positron emission tomography (FDG-PET), 90% of patients (45/50 patients; one failed to perform final FDG-PET due to early death) reached complete responses. Altogether, 17 patients (34%) received consolidation radiotherapy of RNMs with Deauville score ≥ 3. At 5-year median follow-up, the OS and PFS of the entire population were 87.5% (95% confidence interval [CI], 78.7–97.4) and 81.6% (95% CI, 71.4–93.2), respectively. Eleven patients (22%) experienced grade ≥ 3 adverse events, and 4 of them required hospitalization. Our data suggest that in older adults with high-risk c-HL NPLD-driven strategy (without bleomycin) plus consolidation radiotherapy (if needed) may be a promising up-front option, to test in phase II clinical trials for improving survival incidence.
