Abstract

Following the seminal suggestion of Hryniuk of improved outcomes with drug schedules achieving higher dose intensity [DI], we have pursued a series of pilot studies and report here on two using weekly doxorubicin [A] at 20-24 mg/m2, daily oral cyclophosphamide [C] at 60 mg/m2, scheduled G-CSF (filgrastim) [G] at 5 μg/kg (days 2-7 ea. week) given to 37 patients [pts] with median age of 41 (23-62). Because A was given weekly and C daily, this regimen is also dose dense. 5-FU [F] was given to the initial 17 pts (FAC+G), stopped because of hand-foot and because NSABP AC had become a national standard. The remainder received AC+G at the higher A dose. Pts had stage II or IIIA disease, 12/25 negative for both ER and PR, 13/29 positive for HER-2/neu overexpression. There was one admission for febrile neutropenia. Median follow-up is 49 months. Planned therapy was to a cumulative dose of A of 480 mg/m2. DI and toxicity are for all pts. For 21 pts who received no additional chemotherapy (FAC+G, 14/17, AC+G, 7/20), disease-free survival is 80%, with overall survival of 86%. This compares with DFS and OS for pts with 4-9 involved nodes reported by Hudis with Memorial's dose-dense AC of 64 and 70%, respectively [JCO, 1999 17(4): 1118-1126].
