EPOCH dose-adjustment paradigm

Nadir measurements6-150Dose-adjustment6-151
If Nadir ANC at least 0.5 × 109/L 20% increase in etoposide, doxorubicin, and cyclophosphamide above last cycle  
If Nadir ANC less than 0.5 × 109/L on 1 or 2 measurements Same dose(s) as last cycle  
If Nadir ANC less than 0.5 × 109/L on at least 3 measurements 20% decrease in etoposide, doxorubicin, and cyclophosphamide below last cycle 
Or  
If Nadir platelet count less than
25 × 109/L on 1 measurement 
20% decrease in etoposide, doxorubicin, and cyclophosphamide below last cycle

F6-150

Measurements of ANC and platelet nadir are based ontwice weekly CBC only.

F6-151

Dose adjustments above starting dose level(level 1) apply to etoposide, doxorubicin and cyclophosphamide. Dose adjustments below starting dose level (level 1) apply to cyclophosphamide only.
