Neutrophil recovery in elderly breast cancer patients receiving adjuvant anthracycline-containing chemotherapy with pegfilgrastim support
Abstract Shortening duration of chemotherapy-induced neutropenia may reduce risk of infection and aid subsequent chemotherapy delivery. Cycle 1 neutrophil recovery was evaluated in 59 elderly women with breast cancer receiving adjuvant FEC100 (5-fluorouracil 500 mg/m2 , epirubicin 100 mg/m2 and cycl...

Zusammenfassung: | Abstract Shortening duration of chemotherapy-induced neutropenia may reduce risk of infection and aid subsequent chemotherapy delivery. Cycle 1 neutrophil recovery was evaluated in 59 elderly women with breast cancer receiving adjuvant FEC100 (5-fluorouracil 500 mg/m2 , epirubicin 100 mg/m2 and cyclophosphamide 500 mg/m2 ) and randomized to pegfilgrastim primary prophylaxis (PP) from cycle 1, or secondary prophylaxis (SP, i.e., subsequent to a neutropenic event [no G-CSF in cycle 1]). In cycle 1, grade 4 neutropenia occurred in 77% (PP; N = 30) and 72% (SP; N = 29). Duration of grade 3–4 neutropenia was shorter with pegfilgrastim than without. Mean absolute neutrophil count (ANC) recovered above 1.0 × 109 /L by day 9 (pegfilgrastim) versus days 16–18 (without). At last observation (≥day 14 ± 2), no PP patient had ANC |
