| Popis: | Guidelines for using granulocyte colony-stimulating factor (G-CSF) in patients receiving chemotherapies with 10-20% (intermediate) risk for febrile neutropenia (FN) recommend additional assessment of patient-related FN risk factors.The current study evaluated adherence to guideline recommendations and analysed modalities of pegfilgrastim use.Adult cancer patients scheduled to receive a chemotherapy regimen assessed by the investigators as intermediate FN risk and who received pegfilgrastim were prospectively enrolled in this observational study from 2007-2010. Risk factors at study entry, treatment modalities and FN assessment were documented by investigators, whereas guideline adherence was centrally checked in a post-hoc analysis, according to guideline categorizations.Thirty-seven centres enrolled 335 evaluable patients with solid and hematologic neoplasias. Although physicians initially rated the FN risk of all chemotherapies as intermediate, after central re-assessment this applied only to 63.9% of regimens; 21.2% were reassessed as low risk and 14.9% as high risk. Pegfilgrastim was used as primary prophylaxis in 80.3% of all patients. The most frequent FN risk factors considered by physicians when deciding to use pegfilgrastim were female gender, advanced disease, age ≥ 65 years, and anaemia. FN incidence was higher in patients with ≥ 4 FN risk factors than those with4 risk factors (10% vs. 4.3%; p = 0.055) and in patients with severe comorbidity than those without (13.6% vs. 4.5%; p = 0.014). Overall FN rate was 5.7%.Due to the observational design of the study, findings are descriptive in nature. Post-hoc assessment of chemotherapy FN risk was determined by author's opinion in some cases.Overall, there was good adherence of Austrian physicians to guideline recommendations; however, there are chemotherapy regimens and clinical settings in which FN risk assignment is unclear in the literature. FN incidence with pegfilgrastim prophylaxis was similar to that reported in other observational and randomized studies. |
