RESUMO
Data about the timing of autologous stem cell transplantation (ASCT) in peripheral T cell lymphoma (PTCL) are conflicting. We aimed to investigate the impact of the sequence of ASCT on the survival outcomes in patients with PTCL. Analyzes were performed retrospectively in a total of 81 patients, 16 of whom underwent upfront ASCT and 12 received salvage ASCT. In univariate analysis, upfront ASCT reduced the risk of progression and death by 77% (Hazard ratio (HR): 0.23, 95% confidence interval (CI): 0.09-0.60) (p = 0.003) and by 84% (HR: 0.16, 95% CI: 0.5-0.55) (p = 0.003), respectively. However, in multivariate analysis, only salvage ASCT predicted a more favorable progression-free and overall survival (HR: 0.17, 95% CI: 0.06-0.48, p = 0.001 and HR: 0.20, %95 GA: 0.06-0.62, p = 0.005, respectively). In conclusion, regardless of first-line therapy, patients have more favorable outcomes if they receive salvage ASCT. Upfront ASCT does not add clinically significant benefit to survival outcomes.

BACKGROUND: In this retrospective cohort of patients with primary, post-polycythemia vera, or post-essential thrombocythemia myelofibrosis, 57 patients with MF who received ruxolitinib for MF-related symptoms or symptomatic splenomegaly were evaluated. METHODS: The median age of the patients in this cohort was approximately 58 years. Of these, there were 33 patients (57.9%) in INT-1, 23 patients (40.4%) in INT-2, and 1 patient (1.8%) at high risk. Overall, spleen size reduction of at least 35% (spleen response) was achieved in 56.6% and 63.3% of all cohort and INT-1 risk at any time, respectively. RESULTS: Symptom response and clinical improvement were observed in 21.7% and 60.7% of patients, respectively. Anemia and thrombocytopenia were prevalent, but manageable. About 73.7% of patients continued treatment during a median follow-up of 22 months. Two-year OS probability was approximately 84.5% (95% CI, 63.1â94.0%) and 62.3% (95% CI, 37.5â79.6%) for the intermediate-1 and -2 risk groups, respectively. CONCLUSION: Real-life experience in a community-based hospital confirms the efficacy and safety profile of ruxolitinib in intermediate-risk myelofibrosis. Treatment discontinuation rates were lower than those in clinical trials.
