Výsledky klinické studie AETHERA ukázaly, že konsolidační terapie brentuximab vedotinem po vysokodávkované chemoterapii a provedení autologní transplantace kmenových hematopoetických buněk signifikantně prodlužuje přežití bez progrese u pacientů s klasickým Hodgkinovým lymfomem. V této multicentrické retrospektivní analýze sedmi hematologických center České republiky jsme analyzovali klinická data z reálné klinické praxe a výsledky léčby u 39 pacientů léčených konsolidační terapií brentuximab vedotinem od ledna 2015 do prosince 2021. Brentuximab vedotin nebyl nemocným podáván v předchozí léčbě lymfomu a pacienti měli nejméně jeden definovaný rizikový faktor pro další relaps. Medián podaných cyklů brentuximab vedotinu byl 8 (1-16), 82 % pacientů dosáhlo během léčby kompletní remise. Medián sledování byl 28 měsíců, dvouleté přežití bez progrese bylo 66,2 % (95% CI 0,52-0,85) a dvouleté celkové přežití 95 % (95% CI 0,82-1,00). Nejčastějším důvodem ukončení léčby bylo kompletní podání 16 léčebných cyklů (20,5 %), relaps/progrese lymfomu (15,4 %) a stejně tak rozvoj symptomatické periferní neuropatie, která byla v různém stupni závažnosti pozorována u 38,5 % pacientů. Naše data potvrzují deklarovanou účinnost a bezpečnost konsolidační terapie brentuximab vedotinem v reálné klinické praxi.
The results from the clinical trial AETHERA showed that consolidation therapy with brentuximab vedotin after high-dose chemotherapy followed by autologous stem cell transplantation increases progression free survival in high-risk patients with relapsed/refractory classic Hodgkin lymphoma. In this multicenter retrospective analysis from seven hematological centers in the Czech republic we have analysed real-life data of 39 patients treated between January 2015 and December 2021. Brentuximab vedotin was not administered in the previous treatment and the patients were at increased risk of subsequent lymphoma relapse with at least one defined risk factor. The median cycles of brentuximab vedotin administered was 8 (1-16), 82 % of the patients achieved complete remission during the treatment. The median follow-up was 28 months, the 2-year progression-free survival and overal survival were 66,2 % (95 % CI 0,52-0,85) and 95 % (95 % CI 0,82-1,00), respectively. The most common reason for treatment discontinuation was completion of 16 cycles administered (20,5 %) relapse/progression of the lymphoma (15,4 %) and symptomatic peripheral neuropathy as well, that was observed in various severity grades in 38,5 % patients overall. Our data have confirmed efficacy and safety of brentuximab vedotin consolidation therapy in the real-life clinical practice.

In the pre-novel agent era, the median postprogression overall survival (PPS) of patients with classic Hodgkin lymphoma (cHL) who progress after autologous stem cell transplant (ASCT) was 2 to 3 years. Recently, checkpoint inhibitors (CPI) and brentuximab vedotin (BV) have improved the depth and durability of response in this population. Here, we report the estimate of PPS in patients with relapsed cHL after ASCT in the era of CPI and BV. In this multicenter retrospective study of 15 participating institutions, adult patients with relapsed cHL after ASCT were included. Study objective was postprogression overall survival (PPS), defined as the time from posttransplant progression to death or last follow-up. Of 1158 patients who underwent ASCT, 367 had progressive disease. Median age was 34 years (range, 27-46) and 192 were male. Median PPS was 114.57 months (95% confidence interval [CI], 91-not achieved) or 9.5 years. In multivariate analysis, increasing age, progression within 6 months, and pre-ASCT positive positron emission tomography scan were associated with inferior PPS. When adjusted for these features, patients who received CPI, but not BV, as first treatment for post-ASCT progression had significantly higher PPS than the no CPI/no BV group (hazard ratio, 3.5; 95% CI, 1.6-7.8; P = .001). Receipt of allogeneic SCT (Allo-SCT) did not improve PPS. In the era of novel agents, progressive cHL after ASCT had long survival that compares favorably with previous reports. Patients who receive CPI as first treatment for progression had higher PPS. Receipt to Allo-SCT was not associated with PPS in this population.

Voľná cirkulujúca nádorová DNA (circulating tumour DNA – ctDNA) je typ extracelulárnej voľnej DNA (circulating cell-free DNA – cfDNA) uvoľňovaná do krvi pacientov s onkologickým ochorením apoptózou a nekrózou nádorových buniek. Predstavuje alternatívny biomarker, ktorého kvalitatívna i kvantitatívna analýza môže, doplňujúc zobrazovacie vyšetrenie, spresniť hodnotenie liečebnej odpovede u pacientov s Hodgkinovým lymfómom. Ako dynamický parameter by si svoje uplatnenie mohla nájsť pri upresňovaní diagnózy, v skríningu mutácií a pri vstupnej stratifikácii pacienta podľa rizika, v priebehu liečby a po jej ukončení pri hodnotení jej účinnosti aj v ďalšom sledovaní za účelom včasnej predikcie prípadného relapsu.
Circulating tumour DNA (ctDNA) is a type of extracellular circulating cell-free DNA (ccfDNA, cfDNA) released into the blood of cancer patients by apoptosis and necrosis of tumour cells. It represents an alternative biomarker for the qualitative and quantitative analysis that may together with PET/CT imaging refine the assessment of treatment response in patients with Hodgkin lymphoma. As a dynamic parameter, it could be applied for refining diagnosis, initial screening for mutations and patient risk stratification. During treatment and at its the end, it could be used to evaluate treatment efficacy and may also be useful for further monitoring and relapse prediction.

Introduction: We analyzed the incidence, risk factors of central nervous system (CNS) relapse, and outcome of CNS involvement in patients with peripheral T-cell lymphomas (PTCL) from the Czech Lymphoma Study Group Registry NiHiL (Clinical Trial gov. NCT03199066). Materials and Methods: Out of 1,040 patients with PTCL, we identified 29 patients (2.79%) with CNS involvement: 2 patients with primary CNS T cell lymphoma, 11 patients with CNS and systemic disease at diagnosis, and 16 patients (1.54%) at CNS relapse. The most common histology with CNS disease was PTCL, not otherwise specified. Progression-free survival (PFS) was defined as the time interval from diagnosis to progression or death. PFS-2 was defined as the interval from the date of a new relapse until the next relapse. Results: Patients with testicular involvement received intrathecal prophylaxis with methotrexate. High-dose methotrexate-based treatment was administered in 44.8% of patients with CNS disease. Median follow-up was 71.3 months. The difference between the median PFS of 1,027 patients without initial CNS disease (32.6 months) and 11 patients with initial CNS and systemic disease (4.8 months) was significant (p = 0.04). The difference between the median PFS2 in CNS relapses (10.1 months) and 493 relapses outside of CNS (9.1 months) was not significant (p = 0.6). Risk factors for CNS relapses included the following: involvement of more than one extranodal site (p = 0.008), soft tissue involvement (p = 0.003), testicular involvement (p = 0.046), and the presence of B symptoms (p = 0.035). The difference between the median OS of 1,027 patients without initial CNS disease (46.0 months) and 11 patients with initial CNS and systemic disease (18.2 months) was significant (p = 0.02). The median OS2 in CNS relapses was 11.8 months and that in relapses outside of CNS was 21.3 months. CNS involvement was not associated with a significantly worse OS compared to relapsed/refractory patients without CNS involvement (p = 0.1). Conclusions: The incidence of CNS disease at the time of diagnosis and at relapse in PTCL is low and usually associated with other systemic involvement. The prognosis of PTCL with initial CNS involvement is significantly worse when compared to patients without CNS disease at diagnosis. The outcome of CNS relapse is comparable with relapsed PTCL outside of CNS. The optimal treatment is not defined yet.

OBJECTIVES: Polatuzumab vedotin with bendamustine and rituximab (Pola-BR) was approved for treatment of transplant-ineligible patients with relapsed/refractory DLBCL (R/R DLBCL). However, the number of patients treated in the GO29365 trial including the extension cohort was limited, and more data evaluating the efficacy of this treatment regimen is needed. METHODS: We analyzed 21 patients with R/R DLBCL to determine real-life efficacy and safety of Pola-BR regimen. Data of all patients entered the database of the NiHiL project (NCT03199066). RESULTS: Median overall survival was 8.7 months, and progression-free survival 3.8 months. The overall response rate was 33%. Grade 3-4 neutropenia was detected in 29%, thrombocytopenia in 38%, anemia in 19%, infections in 24% cases, and peripheral neuropathy in 5%. Discontinuation of treatment was caused by progression in 50%, adverse events in 31%, and intended bridging to CAR-T therapy in 19%. CONCLUSION: Although the outcome of patients is worse than in GO29365 trial, the use of Pola-BR regimen in the real world demonstrates tolerable toxicity profile and efficacy in transplant-ineligible patients with R/R DLBCL. Moreover, this regimen might represent a perspective option as a bridge to CAR-T therapy.

Burkitt lymphoma (BL) is a rare subtype of non-Hodgkin's lymphoma with an aggressive course. To refine the individual patient's prognosis, the International Prognostic Index for BL (BL-IPI) was recently developed and 4 risk factors (RF) were determined as optimal prognostic cut-off by multivariate analysis: age ≥40 years, lactate dehydrogenase >3× upper limit of normal, ECOG performance status ≥2, and central nervous system involvement. The BL-IPI distinguishes 3 prognostic groups, low (without RF), intermediate (1 RF), and high risk (2-4 RF), with significant differences in survival. The aim of the current project was to perform an external validation of the BL-IPI in 101 patients from the Registry of Czech Lymphoma Study Group diagnosed between 1999 and 2016 (median age, 45 years). The median follow-up was 50.4 months. The induction treatment included rituximab plus chemotherapy in 82% and chemotherapy alone in 18%. The overall response rate was 78% and the complete remission rate was 73%. According to BL-IPI, low/intermediate/high risk was present in 21/35/45% of patients, showing high similarity to the training BL-IPI US (United States) dataset (18/36/46%). There were significant differences in progression-free survival (PFS) and overall survival (OS) between patients with high vs. intermediate risk (PFS: hazard ratio 0.16, 95% confidence interval 0.08-0.31, p<0.0001; OS: hazard ratio 0.17, 95% confidence interval 0.09-0.35, p<0.0001) but not between patients with low vs. intermediate risk. The 3-year OS probability according to BL-IPI with low/intermediate/high risk was 96/76/59% in the BL-IPI training dataset vs. 95/85/45% in our external validation cohort; the 3-year PFS probability with low/intermediate/high risk was 92/72/53% in the BL-IPI training dataset vs. 95/85/42% in our cohort. In summary, our external validation of the BL-IPI confirmed a good separation of high-risk patients, who have a poor prognosis and for whom the new therapeutic approaches are needed; patients with low and intermediate risk had favorable clinical outcomes, and differences between these groups were not significant, likely due to a small number of patients.
