Abstract
e14513 Background: febrile neutropenia (FN) remains one of the most serious side effects of chemotherapy treatment, which is life-threatening. Late consequence of FN is dose reduction and delaying of therapies. Actual guidelines allows granulocyte-colony-stimulating factors (G-CSF) in management of profound FN in addition to antibiotics and supportive care Methods: it is an original prospective study, approved by local ethics comitee, which included 73 patients with confirmed malignancy, treated in our Institute with chemotherapy, who developed febrile neutropenia (FN) and were hospitalised. Patients with myeloablative chemotherapy and bone marrow transplantation support, severe renal impairment, abnormal liver function or with a history of allergic reactions to the antibiotics were excluded from the study. There were recorded 96 episodes of grade 4 FN (1-3 episodes / patients). Each of one was hospitalised according to institutional guideline but with a dose of G-CSF of 16 µg/Kg/day i.v. continous infusion Results: median age of included patients was 59 years, with approximately 48 % male and 52% female, whithout significance in terms of recovery from FN (p = 1.00). 30% of the patients had prophilactic G-CSF administrated, but not significant for recovery from aplasia for included patients (p = 0.34). Median chemotherapy line responsible for FN was 2, and median cycle which produced FN was 3. Median level of neutrophiles (PMN) 450/mm3 and leucocytes (WBC) 1875/ mm3 at time of FN, 10 patients being in profound FN (PMN < 100/mm3). Median time to recovery was 25.5 hours for 72 included patients, with 1 patient dead whithout recovery. Predictive factors for shortened recovery were lower levels of reactive protein C (p < 0.001) and procalcitonine (p = 0.002) and higher WBC (p = 0.006) and PMN (p < 0.001) at time of administration of responsible chemotherapy regimen for FN. The earlier cycle responsible, between a line of chemotherapy, for FN, the better chance for patient to have shortened duration of FN (p < 0.0001). Conclusions: continous i.v. administration of G-CSF could represents a very effective alternative for patients with profound febrile neutropenia, with the shortest ever reported interval for neutrophiles recovery
