Usual Adult Dose for Hodgkin's Disease

As a single agent:
-Initial dose: Single or divided doses of 2 to 4 mg/kg/day orally for one week (to minimize the nausea and vomiting experienced by a high percentage of patients beginning therapy)
-Maintenance dose: 4 to 6 mg/kg/day orally until maximum response is obtained or until the white blood count falls below 4000 or the platelets fall below 100,000; when maximum response is obtained the dose may be maintained at 1 to 2 mg/kg/day orally
-Discontinue therapy for hematologic or other toxicity until satisfactory recovery, then resume therapy (at the discretion of the physician based on patient evaluation and laboratory studies) at 1 to 2 mg/kg/day

In combination with other anticancer drugs:
-The dose of this drug should be reduced (e.g., in the MOPP regimen, the dose is 100 mg/m2/day for 14 days)

Comments:
-Dosing given here is manufacturer suggested. Local and institutional protocol should be consulted.
-Doses should be based on the patient's actual weight; however, the estimated lean body mass (dry weight) is used if the patient is obese or if there has been a spurious weight gain due to edema, ascites, or other forms of abnormal fluid retention.

Use: In combination with other anticancer drugs for the treatment of Stage III and IV Hodgkin's disease; this drug is used as part of the MOPP (nitrogen mustard, vincristine, procarbazine, prednisone) regimen

Usual Pediatric Dose for Hodgkin's Disease

-Maintenance dose: 100 mg/m2/day orally until maximum response is obtained or until leukopenia or thrombocytopenia occurs; when maximum response is obtained the dose may be maintained at 50 mg/m2/day orally
-Discontinue therapy for hematologic or other toxicity until satisfactory recovery, then resume therapy (at the discretion of the physician based on patient evaluation and laboratory studies).

Dose Adjustments

If during the initial treatment the total white cell count falls to 3000/mm3 or the platelet count to 80,000/mm3, therapy should be suspended temporarily until the leucocyte and/or platelet levels recover, when therapy with the maintenance dose may be resumed.
