RESUMEN
OBJECTIVES: To describe the French routine use of G-CSF in patients treated for breast cancer as per the EORTC recommendations. PATIENTS AND METHODS: A prospective multicenter observational study conducted between February 2008 and September 2009 in 869 breast cancer patients treated by chemotherapy (CT) and for whom G-CSF treatment will be delivered in primary (PP) or secondary prophylaxis. RESULTS: The mean age was 55 years. A total of 80.3% of CT was in neoadjuvant/adjuvant setting (NAS). PP was delivered in 78.9% of the NAS patients and 67.5% in metastatic situation. Of the 702 evaluable patients, incidences of severe (SN) and febrile neutropenias (FN) in patients who received PP were 9.3% and 4.2%, respectively. In patients who did not received G-CSF at first cycle, SN and FN were 12.4% and 7.3%, respectively. The use of PP was mainly driven by the type of CT for patients treated in the NAS and by patient or disease related risk factors in the locally advanced/metastatic setting. CONCLUSION: This study has shown that the use of G-CSF was in accordance with the 2010 updates of the EORTC recommendations. However, G-CSF appears more widely used in the routine practice.

OBJECTIVES: Patient adherence is a challenge in oncology and hematology practice. Hormone therapy data in breast cancer suggest insufficient adherence and poor persistence. Limited data are available for targeted therapies (TT) including tyrosine kinase and mammalian target of rapamycin inhibitors. METHODS: We performed a prospective survey using a 15-item questionnaire in patients with solid tumors and hematologic malignancies receiving oral anticancer therapy. Treatment duration, setting (adjuvant vs. metastatic), cancer type, age, and comedication were recorded. RESULTS: 201 patients (median age 65.5 years) participated, 102 with TT and 99 with hormone therapy or chemotherapy (HC). The median time of drug intake was 11.0 months. Written information was more frequently given to TT patients (68.6 vs. 23.2%, p < 0.0001). TT and HC patients showed equal adherence to therapy (72.5 vs. 69.6%, p = n.s.) despite TT patients experiencing more side effects (p < 0.0001) and taking more concomitant oral medication (p = 0.0042). Forgotten doses were the leading cause of nonadherence in HC patients (83%, as compared to 54% in the TT group), whereas dose reduction by the patient was higher in the TT group (32 vs. 17%). CONCLUSIONS: Despite advances in providing information to patients leading to better adherence among TT patients, efforts towards better patient education are warranted including dedicated staff for monitoring outpatient anticancer oral therapy.
