- W4283382900 abstract "Background: Hodgkin lymphoma (HL) is a hematologic malignancy with a high rate of curability. However, 5 to 20% are primary refractory to treatment or relapse after achieving a complete remission (CR) and present a therapeutic challenge. Aims: Our study aims to evaluate the clinical characteristics, treatment patterns, as well as therapeutic results in patients with refractory/ relapsed HL (R/R HL) in a Tunisian center. Methods: It is a retrospective study about adult patients (<60 years old) with R/R HL, treated between January 2008 and Mars 2020 at the hematology, oncology, and radiotherapy departments of the hospital of Sfax, Tunisia. The first-line treatment was based on ABVD in favorable early stages and BEACOPP regimens in advanced stages and localized stages with a bulky mediastinal mass. The standard of care for R/R HL was salvage chemotherapy followed by autologous stem cell transplantation (ASCT) in the national bone marrow transplant center in Tunis. The date of the point is in July 2021. Results: A total of 55 patients were enrolled, which represents 25% of our series of HL managed in this period. The median age was 30 years (range 17-59), and the sex ratio was 1.3. Twenty-five patients (45%) presented with refractory disease. Among the 30 patients (55%) who relapsed, 19 patients (63%) relapsed within 12 months after achieving CR. At relapse, advanced stage, anemia, and B-symptoms were respectively recorded in 60%, 33%, and 53% of cases. Two patients died before salvage chemotherapy (CT), so 53 patients were treated. Second-line CT regimens used were Cytarabine-based regimens (DHAC/DHAP) in 74% of cases, Gemcitabine-based regimens (IGEV) in 19%, and ICE in 7% of cases respectively. IGEV was the most effective regimen to mobilize peripheral blood stem cells (69% vs 30% with Cytarabine-based regimens). A CR was noted in 61% of cases. Radiotherapy was associated with CT in 35% of cases. Only 13 patients (42% of eligible patients) benefited from ASCT. The 5-year overall survival estimate for all patients was 46%, and 5-year PFS was 41%. Chemoresistance to salvage therapy, ≥ 2 lines of salvage therapy, non-realization of ASCT, and insufficient response after treatment were predictive adverse prognostic factors (p<0.001). Summary/Conclusion: Our study showed that CR and feasibility of ASCT were lower than that reported in international studies (61% vs 76%, and 46% vs 69 to 100% respectively), which incites us to a better involvement of ASCT. Besides, the association of new therapeutic agents such as Brentuximab Vedotin should be considered in our patients with chemoresistant HL." @default.
