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.

Untreated

DA-EPOCH-R

back to top

DA-R-EPOCH: Dose Adjusted Etoposide, Prednisone, Oncovin (Vincristine), Cyclophosphamide, Hydroxydaunorubicin (Doxorubicin), Rituximab

Synonyms: DA-R-EPOCH-R

Structured Concept: C63461 (NCI-T), C1882521 (NCI-MT/UMLS)

Regimen

Study Evidence
Wilson et al. 2014 Phase II

Chemotherapy

Supportive medications

21-day cycle for 6 to 8 cycles

Dose-adjustments

  • Start cycle 1 as described above.
  • Obtain CBCs twice per week for nadir measurements.
  • If nadir ANC >500, increase etoposide, doxorubicin, and cyclophosphamide by 20% compared to previous cycle.
  • If nadir ANC <500 on 1 or 2 measurements, use same doses as last cycle.
  • If nadir ANC <500 on at least 3 measurements, decrease etoposide, doxorubicin, and cyclophosphamide by 20% compared to previous cycle.
  • And/or if nadir platelet count <25 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 >1,000 and platelets >100. If counts are below those levels, check daily CBC and continue growth factor support until counts are adequate and next cycle can start.
