| Popis: | Introduction: MONITOR-GCSF is a European prospective observational study of practice patterns and outcomes of patients treated with Sandoz' filgrastim (EP-2006) in the prophylaxis of chemotherapy-induced febrile neutropenia (CIN/FN). Objectives: To describe patients, treatment patterns of EP-2006, and outcomes in the breast cancer cohort of the MONITOR-GCSF study. Methods: Prospective observational study following 466 evaluable patients from 23 centers in Europe for up to 6 cycles within a single chemotherapy line including a total of 2714 cycles. Results: Median age was 56y (range 25-91); all but 3 patients were female. Table 1 presents chemotoxicity in terms of % FN risk and prophylaxis type. GCSF was correctly initiated as either primary or secondary prophylaxis per EORTC guideline recommendations (considering chemotherapy-related FN risk and patient-related factors) in 62% of patients. Eleven percent were undertreated, i.e., secondary prophylaxis when primary was indicated–either when CIN/FN risk >20% or when CIN/FN risk was 10-20% in combination with patient-related risk factors. Twenty-seven percent were overtreated, i.e., primary or secondary when not indicated–either primary prophylaxis in Table 1 n%Chemotherapy toxicity (risk of FN)>20%25053.8 10-20%17036.5 Conclusions: Variation in treatment with biosimilar GCSF in breast cancer patients is evident in terms of decision to treat with primary prophylaxis relative to guideline recommendations as well as day of initiation, duration and dose, yet incidence of CIN/FN and related events is low. Forthcoming analyses will determine whether variability in treatment is associated with differential outcomes.
