Outcome of patients with diffuse large B-cell lymphoma and testicular involvement - real world data.

Patients with testicular lymphoma are at an increased risk of central nervous system (CNS) disease. Optimal strategy for CNS relapse prevention is unknown. We analyzed treatment strategies, cumulative incidence of CNS relapse and prognosis in 229 patients with diffuse large B-cell lymphoma (DLBCL) and testicular involvement: 157 primary testicular lymphomas (PTL) in clinical stages IE/IIE and 72 patients in advanced stages (T-DLBCL) IIIE/IV.

Several factors that predict the outcome of large B-cell lymphoma patients who relapse/progress after chimeric antigen receptor (CAR) T-cell therapy can be identified before cell administration.

Aim: The aim of this study was to analyse the outcomes of patients with large B-cell lymphoma (LBCL) treated with chimeric antigen receptor T-cell therapy (CAR-Tx), with a focus on outcomes after CAR T-cell failure, and to define the risk factors for rapid progression and further treatment.

Methods: We analysed 107 patients with LBCL from the Czech Republic and Slovakia who were treated in ≥3rd-line with tisagenlecleucel or axicabtagene ciloleucel between 2019 and 2022.

Results: The overall response rate (ORR) was 60%, with a 50% complete response (CR) rate.

Overall survival of patients with cHL who progress after autologous stem cell transplant: results in the novel agent era.

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.

Ibrutinib in mantle cell lymphoma: a real-world retrospective multi-center analysis of 77 patients treated in the Czech Republic.

Ibrutinib revolutionized therapy for relapsed/refractory (R/R) mantle cell lymphoma (MCL). Real-world data on the outcome of unselected patients are still limited. We analyzed 77 R/R MCL patients receiving ibrutinib with at least one prior systemic anti-lymphoma therapy.

Brentuximab vedotin plus doxorubicin, vinblastine, and dacarbazine in patients with advanced-stage, classical Hodgkin lymphoma: A prespecified subgroup analysis of high-risk patients from the ECHELON-1 study.

Approximately one-third of patients diagnosed with Hodgkin lymphoma presenting with Stage IV disease do not survive past 5 years. We present updated efficacy and safety analyses in high-risk patient subgroups, defined by Stage IV disease or International Prognostic Score (IPS) of 4-7, enrolled in the ECHELON-1 study that compared brentuximab vedotin plus doxorubicin, vinblastine, and dacarbazine (A + AVD) versus doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) as first-line therapy after a median follow-up of 37.1 months.

Rituximab, Cyclophosphamide and Dexamethasone (RCD) Chemoimmunotherapy for Relapsed Chronic Lymphocytic Leukaemia.

High doses of corticosteroids in combination with rituximab remain an alternative in the treatment in relapsed or refractory chronic lymphocytic leukaemia (CLL) in the current era of targeted therapies. This study retrospectively evaluates the efficacy of an RCD (rituximab, cyclophosphamide and dexamethasone) regimen in the treatment of 51 patients with relapsed CLL (median age, 72 years). Unfavourable prognostic features, such as Rai stage III/IV, unmutated IGHV, del11q, TP53 mutation/deletion, complex karyotype and bulky lymphadenopathy, were frequent.

Treatment of Relapsed/Refractory Hodgkin Lymphoma: Real-World Data from the Czech Republic and Slovakia.

: Clinical trials have demonstrated the effectiveness of the CD30-targeted antibody-drug conjugate brentuximab vedotin (BV) for the treatment of relapsed/refractory Hodgkin lymphoma (R/R HL). In this study, we report on outcomes with BV in a real-world setting using data collected in clinics in the Czech Republic and Slovakia. : Clinical and epidemiological data for patients with R/R HL who received treatment with BV at eight centers across the Czech Republic and Slovakia were examined.

Experiences in the treatment of refractory chylothorax associated with lymphoproliferative disorders.

Background: Chylothorax is a rare condition which can be associated with malignant lymphoproliferative disorders (LPDs). We retrospectively analyzed the results of the conservative treatment of 10 patients with persistent non-traumatic malignant chylothorax.

Results: Conservative treatment lead to a decline of chylothorax after mean of 66 days and consisted of the treatment of the underlying disease and of simultaneous long-term supportive care (drainage of the thoracic cavity, dietary measures and nutrition management).

The influence of maintenance therapy of rituximab on the survival of elderly patients with follicular lymphoma. A retrospective analysis from the database of the Czech Lymphoma Study Group.

The rituximab maintenance (RM) therapy for follicular lymphoma is effective and clinically well tolerated, however there is limited data regarding this from the elderly segment of the population. This analysis was performed to evaluate the efficacy of RM in elderly patients 65 years of age and older and to assess the influence of the induction therapy with immunochemotherapy (R-CHEMO) on the treatment outcome in a real world setting. A total of 232 consecutive patients treated with first-line R-CHEMO and RM (RM1 group; n = 158) or observation (RM0 group; n = 74) were analyzed.

Maintenance rituximab in newly diagnosed mantle cell lymphoma patients: a real world analysis from the Czech lymphoma study group registry.

We analyzed 495 MCL patients from the Czech Lymphoma Study Group data registry. With the median follow-up of 4.4 years, 51.

Frontline intensive chemotherapy improves outcome in young, high-risk patients with follicular lymphoma: pair-matched analysis from the Czech Lymphoma Study Group Database.

Optimal frontline treatment in younger high tumor-burden risk follicular lymphoma patients remains a challenge given the reduced efficacy of standard immunochemotherapy (R-CHOP) in widespread disease and unclear role of intensive induction. The retrospective non-randomized pair-matched (1:3) analysis compared 48 intermediate/high Follicular Lymphoma International Prognostic Index (FLIPI) patients receiving intensive rituximab sequential chemotherapy (R-SQ) with 144 random controls (R-CHOP) matched for age, FLIPI score, and maintenance delivery. Complete response rates were 91.

Role of rituximab in treatment of patients with primary central nervous system lymphoma: a retrospective analysis of the Czech lymphoma study group registry.

We have investigated whether the addition of rituximab to methotrexate, procarbazine, vincristine, radiotherapy and cytarabine was associated with improved outcome of primary central nervous system lymphomas (PCNSL). Of 164 patients, 49 received rituximab. Median age was 63 years, median Karnofsky performance score (KPS) was 60 and median follow-up of living patients was 59.

Ten years' experience with four cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone, procarbazine (BEACOPP)-escalated followed by four cycles of baseline-dose BEACOPP in patients with advanced stage Hodgkin lymphoma: a single-center, retrospective study.

The HD-9 trial showed that eight cycles of BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone, procarbazine)-escalated led to significant improvements in response rate, progression-free survival and overall survival over COPP/ABVD (cyclophosphamide, vincristine, prednisone, procarbazine/doxorubicin, bleomycin, vinblastine, dacarbazine) therapy. This monocentric retrospective study was performed to evaluate 10 years of experience with four cycles of BEACOPP-escalated and four cycles of BEACOPP-baseline outside of clinical trials. The outcomes were assessed in 78 patients with newly diagnosed advanced stage Hodgkin lymphoma.

[Lymphomatoid granulomatosis - the past and present].

Background: Lymphomatoid granulomatosis (LyG) is a rare multisystemic angiocentric and angiodestructive B lymphoproliferative disease that was first described by Liebow in 1972. Disease was then in the "gray zone" between vasculitis and lymphoproliferative disease. LyG is currently categorized as a primary B lymphoproliferative disease associated with Epstein-Barr (EB) virus according to the World Health Organization (WHO) classification of tumours.

Treatment of high-risk aggressive B-cell non-Hodgkin lymphomas with rituximab, intensive induction and high-dose consolidation: long-term analysis of the R-MegaCHOP-ESHAP-BEAM Trial.

We have studied the feasibility and efficacy of intensified R-MegaCHOP-ESHAP-BEAM therapy in high-risk aggressive B-cell lymphomas. Altogether 105 patients (19-64 years) with diffuse large B-cell lymphoma (DLBCL), primary mediastinal B-cell lymphoma (PMBL) or follicular lymphoma grade 3 (FL3) with an age-adjusted International Prognostic Index of 2-3 were recruited. Treatment consisted of three cycles of high-dose R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone), followed by three cycles of R-ESHAP (rituximab, etoposide, methylprednisolone, cytarabine, cisplatin) and high-dose consolidation with BEAM (BCNU, etoposide, cytarabine, melphalan) and autologous stem cell transplant.
