Total tried: Correct: Wrong:
Regimen : Stanford V for Hodgkin lymphoma.
Cycle: three 4-week cycles. Total regimen is 12 weeks.
- Doxorubicin, 25 mg/m2, IV, weeks 1, 3, 5, 7, 9 and 11
- Mechlorethamine, 6 mg/m2, IV, weeks 1, 5 and 9
- Vinblastine, 6 mg/m2, IV, weeks 1, 3, 5, 7, 9 and 11
- Vincristine, 1.75 mg/m2, IV, weeks 2, 4, 6, 8, 10 and 12.
- Bleomycin, 5 units/m2 , IV, weeks 2, 4, 6, 8, 10 and 12.
- Etoposide, 60 mg/m2 per day IV on 2 consecutive days in weeks 3, 7, 11
- Prednisone, 40 mg/m2 PO every other day for 10 weeks then tapered by 10 mg PO every other day between week 10 and 12

lb equals 4382.00 mg kg
- The patient height
= 5 feet 10 inches
= ( 5 × 12 + 10 ) inch
= 70 inch
= 70 × 2.54 cm
= 177.8 cm - patient weight
= 341 lb
= 341 × 0.454 kg
= 154.8 kg -
BSA for the patient is
BSA `= \quad sqrt(( Height (cm) × Weight (Kg) )/(3600))`
` \quad \quad \quad = sqrt(( 177.8 \quad cm × 154.8 \quad Kg )/(3600)) = 2.7650 ` m2
-
Here for prednisone :
patient dose for every other day
= `( 40 \quad mg)/(1quad m^2) × 2.7650 m^2
= 111 ` mg
Hence, dose for first 10 weeks
= ` 111 \quad mg × 35` (days of treatment)
= 3885 mg
And dose for `11^(th)` and `12^(th)` weeks (7 days of treatment tapered by 10 mg)
= ( 101 + 91 + 81 + 71 + 61 + 51 + 41 ) mg
= 497 mg
Therefore, total dose for 12 weeks cycle
= 3885 mg + 497 mg = 4382 mg `Ans.`
