Note: Mediastinal gray-zone lymphome (MGZL) is considered intermediate between primary mediastinal B-cell lymphoma (PMBL) and nodular sclerosis Hodgkin lymphoma (NSHL). Given that it is treated more similarly to the non-Hodgkin lymphoma, it is included here.
DA-R-EPOCH: Dose Adjusted Rituximab, Etoposide, Prednisone, Oncovin (Vincristine), Cyclophosphamide, Hydroxydaunorubicin (Doxorubicin)
|Wilson et al. 2014 (NCI 93-C-0133MGZL)||Phase 2|
Note: this should be considered a substudy under the master protocol NCI 93-C-0133.
- Rituximab (Rituxan) 375 mg/m2 IV once per cycle or 1 day before the start of EPOCH (depending on reference)
- Etoposide (Vepesid) 50 mg/m2/day IV continuous infusion over 96 hours, started on day 1 (total dose per cycle: 200 mg/m2)
- Vincristine (Oncovin) 0.4 mg/m2/day IV continuous infusion over 96 hours, started on day 1 (total dose per cycle: 1.6 mg/m2)
- Cyclophosphamide (Cytoxan) 750 mg/m2 IV over 15 minutes once on day 5
- Doxorubicin (Adriamycin) 10 mg/m2/day IV continuous infusion over 96 hours, started on day 1 (total dose per cycle: 40 mg/m2)
- Prednisone (Sterapred) 60 mg/m2 PO twice per day on days 1 to 5
- Filgrastim (Neupogen) 5 mcg/kg SC once per day, starting on day 6 and continuing until ANC greater than 5000/uL past nadir
- PCP prophylaxis with ONE of the following:
- Only in García-Suárez et al. 2007: Darbepoetin alfa (Aranesp) 2.25 mcg/kg SC when hemoglobin concentration was less than or equal to 10 g/dL.
21-day cycle for 6 to 8 cycles
- Start cycle 1 as described above.
- Obtain CBCs twice per week for nadir measurements.
- If nadir ANC greater than 500/uL, increase etoposide, doxorubicin, and cyclophosphamide by 20% compared to previous cycle.
- If nadir ANC less than 500/uL on 1 or 2 measurements, use same doses as last cycle.
- If nadir ANC less than 500/uL on at least 3 measurements, decrease etoposide, doxorubicin, and cyclophosphamide by 20% compared to previous cycle.
- And/or if nadir platelet count less than 25 x 109/L on at least 1 measurement, decrease etoposide, doxorubicin, and cyclophosphamide by 20% compared to previous cycle.
- Dose adjustments below the cycle 1 starting dose only applies to cyclophosphamide. The lowest etoposide and doxorubicin would be dosed at is the original cycle 1 dose.
- Can start new cycle every 21 days if ANC greater than 1000/uL and platelets greater than 100 x 109/L. If counts are below those levels, check daily CBC and continue growth factor support until counts are adequate and next cycle can start.

Relapsed or refractory
Brentuximab vedotin monotherapy
|Jacobsen et al. 2015 (SGN35-012)||Phase 2, <20 pts in this subgroup|
This regimen was evaluated in patients with CD30+ non-Hodgkin lymphoma, as determined by immunohistochemistry.
Antibody-drug conjugate therapy
- Brentuximab vedotin (Adcetris) 1.8 mg/kg IV over 30 minutes once on day 1
