Purpose. Discrepancies in the quoted prednisone dosages in the regimens reported as the only standard CHOP regimen stimulated our interest in reviewing the medical literature regarding this issue and to assess whether practicing hematologists and oncologists in the U.S. are aware of the different dose schedules of prednisone in the published CHOP programs. Methods. Sixteen textbooks and chemotherapy reference books were reviewed. A MEDLINE search of English-language articles published between January 1970 and December 1998 was performed. An eight-point questionnaire was sent via e- mail with responses obtained from 421 hematology/oncology physicians in the U.S. Results. Sixteen textbooks and chemotherapy reference books reviewed quoted only one prednisone dosage as part of the standard CHOP regimen; the prednisone dosages quoted as standard varied between publications. More than 4,000 eligible non-Hodgkin's lymphoma patients have been treated with the CHOP chemotherapy as part of 43 different clinical trials reviewed. The dosages of prednisone and prednisolone used varied among six different levels. Thirty percent (127/421) of practicing U.S. physicians were not aware of the existence of more than one prednisone dose schedule as part of the CHOP regimen. The three most frequently used dosages are 100 mg/days 1-5 (67%), 100 mg/m2/days 1-5 (17%), and 60 mg/m2/days 1-5 (13%). Conclusions. Discrepancies in steroid dosages used as part of the reported standard CHOP regimens are common and not well recognized in the medical literature nor by practicing U.S. hematologists/oncologists. Based on this study, a prednisone dose of 100 mg/day for five days should be considered the standard dose.
