From the Guidelines
For relapsed bulky T-lymphoblastic lymphoma that has failed Nelarabine, cyclophosphamide, and etoposide combination therapy, high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is the most potentially curative approach, as supported by the most recent guidelines 1.
Treatment Options
- Allogeneic hematopoietic stem cell transplantation (HSCT) represents the most potentially curative approach if a suitable donor is available and the patient is eligible.
- Before transplant, disease control can be attempted with alternative chemotherapy regimens such as:
- DHAP (dexamethasone, high-dose cytarabine, cisplatin)
- ICE (ifosfamide, carboplatin, etoposide)
- For patients with CD30 expression, brentuximab vedotin at 1.8 mg/kg IV every 3 weeks may be effective, as shown in a pivotal phase II multicenter study 1.
Novel Targeted Therapies
- Venetoclax (400 mg daily) for BCL-2 expressing disease
- Clinical trials of JAK inhibitors like ruxolitinib for JAK-STAT pathway mutations
- CAR T-cell therapy, particularly CD7-directed constructs, shows promise in early trials for T-cell malignancies
Considerations
- Enrollment in clinical trials should be prioritized when possible, as standard options are limited after multiple relapses.
- Treatment selection should be based on the patient's performance status, comorbidities, prior therapy toxicities, and disease-specific factors like immunophenotype and molecular characteristics, with the goal of achieving remission to enable definitive therapy with allogeneic transplantation.
- The use of brentuximab vedotin as a consolidating treatment following HDCT and ASCT has been shown to improve tumor control in patients with certain risk factors, such as primary disease progression or early disease recurrence 1.

From the Research
Treatment Options for Relapsed Bulky T-LBL Refractory to Nelarabine, Cyclophosphamide, and Etoposide Combination Therapy
- For patients with relapsed bulky T-lymphoblastic lymphoma (T-LBL) that is refractory to Nelarabine (Arranon), Cyclophosphamide (Cytoxan), and Etoposide (VePesid) combination therapy, alternative treatment options may include:
- Hematopoietic stem cell transplantation (HSCT) after achieving remission with a different salvage therapy regimen 2
- Allogeneic stem cell transplant (alloSCT) after achieving complete remission with nelarabine combination therapy 3
- Daratumumab and nelarabine combination therapy, which has shown promise in achieving deep complete remission in patients with early relapses of T lymphoblastic lymphoma and T-ALL 4
- It is essential to note that the efficacy and safety of these treatment options may vary depending on individual patient factors, such as age, performance status, and prior treatment history.
Considerations for Treatment
- Nelarabine has shown single-drug activity in relapsed T-lymphoblastic leukemia/lymphoma and offers a curative option with subsequent stem cell transplantation 5
- Combination therapy with nelarabine has been associated with improved survival in pediatric and adult patients with relapsed or refractory T-ALL/LBL 3
- The risk of neurotoxicity and other adverse effects should be carefully considered when selecting a treatment regimen, particularly in patients who have previously received nelarabine or other neurotoxic agents 3, 5, 6
