EPOCH

EPOCH: Etoposide, Prednisone, Oncovin, Cyclophosphamide, Hydroxydaunorubicin

Regimen #1, Wilson, et al. 1993 - original EPOCH protocol

21-day cycles x 6-8 cycles

Regimen #2, Wilson, et al. 2002 - dose-adjusted EPOCH

21-day cycles x 6-8 cycles

Dose-adjustments for EPOCH protocol:

  • Start cycle 1 as described above
  • Obtain twice per week CBCs 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 Q21days 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.

Historic dose adjustments for hematologic toxicity: These adjustments were in the original paper for standard EPOCH, which are much less relevant due to growth factor support.
If ANC on day 1 is:

  • >1,500, full dose cyclophosphamide
  • 1,000-1,500, reduce cyclophosphamide by 187 mg/m2 (equal to 25% dose reduction)
  • <1,000, hold EPOCH
  • If ANC nadir is <500, reduce cyclophosphamide an additional 187 mg/m2
  • If ANC nadir is >500 and patient had previously been dose-reduced, increase cyclophosphamide dose by 187 mg/m2

R-EPOCH

R-EPOCH: Rituximab, Etoposide, Prednisone, Oncovin, Cyclophosphamide, Hydroxydaunorubicin

Regimen #1, Wilson, et al. 1993 - original EPOCH protocol (which did not include rituximab)

21-day cycles x 6-8 cycles

21-day cycles x 6-8 cycles

Dose-adjusted R-EPOCH protocol

  • Start cycle 1 as described above
  • Obtain twice per week CBCs for nadir measurements
  • If nadir ANC >500, increase etoposide, doxorubicin, and cyclophosphamide by 20% compared to previous cycle.
