624. Hodgkin Lymphoma and T/NK Cell Lymphoma—Clinical Studies: Combination Chemotherapy and Biomarkers of Response in Hodgkin Lymphoma
Conclusion cited from the abstract:
The addition of Brentuximab vedotin and Rituximab to combination risk adapted chemotherapy (without cyclophosphamide, etoposide or bleomycin) for newly diagnosed Hodgkin Lymphoma appears to be safe in children, adolescents and young adults. Our results show significant promise with a CR rate of 100%, 58% rapid early response and significant reduction in the use of toxic chemotherapy and radiation. The EFS/OS to date is 100% with a median follow up time of greater than 3.5 years.

Conclusion cited from the abstract: This is the first study comparing two strategies of treatment in high risk stage IIB lymphoma patients included in two large randomized clinical trials. PFS of these patients was 88.0% (95%CI = [81.2%; 92.4%]) at 4 years and similar regardless the study treatment. Baseline TMTV and PET2 response were the main factors influencing the outcome of high risk stage IIB lymphoma patients.

Conclusion cited from the abstract:
This long-term analysis confirms the superior tumor control of 2+2 as compared to 4xABVD in patients ≤60 with early unfavorable HL. However, this does not translate into an OS difference. At longer follow-up, there is no difference regarding second primary malignancies between the groups. In comparison to 4xABVD, the 2+2 regimen spares a significant number of patients from the burden of cancer recurrence and additional treatment without increased long-term toxicity. Therefore, 2+2 remains the GHSG standard for patients with early unfavorable HL ≤60.

Conclusion cited from the abstract: BV-AVD in stage II-IV HIV-cHL was efficacious although neutropenia and neuropathy were increased compared to the non-HIV population. The 2-year PFS estimate was 86% for the entire cohort and 87% for advanced stage HIV-cHL. Major interactions with strong CYP3A4 inhibitors lead to toxicity and must be avoided. The etiology of the CD4 increase is under investigation and may have implications for future therapy.

Conclusion cited from the abstract: Analysis of ctDNA allows detecting tumor-specific mutations in R/R cHL. The longitudinal tracking of circulating DNA mutations in these patients identifies two different patterns of clonal evolution associated with sensitivity (clonal reshaping) or resistance (clonal persistence) to checkpoint blockade.
Conclusion cited from the abstract: Two cycles of BV in R/R HL patients who are treated by ICE chemotherapy allows a CMR in 69.2 % of evaluable patients with sufficient harvest for an ASCT. These results are comparable to other salvage chemotherapies only after two cycles with acceptable toxicities.
