Purpose: The aim of the present study was to evaluate the incidence and explore the risk factors of febrile neutropenia (FN) in patients with esophageal cancer receiving neoadjuvant docetaxel, cisplatin, and 5-fluorouracil (DCF) chemotherapy in real-world settings.
Methods: We retrospectively reviewed clinical data of 128 consecutive patients with esophageal cancer. Specifically, these patients underwent neoadjuvant DCF chemotherapy with prophylactic antibiotic administration at our institution between July 2009 and January 2015. Two FN-related endpoints were set as follows: definite FN (dFN) defined as grade 4 neutropenia at the onset of fever and clinically suspected FN (csFN), which included both patients with dFN and patients without grade 4 neutropenia but with deteriorating grade 3 neutropenia at the onset of fever who were clinically diagnosed with FN for which they underwent treatment. The risk factors for dFN and csFN were evaluated based on patients' characteristics.
Results: A total of 72 (56.3%) patients developed grade 3 or grade 4 neutropenia and 26 (20.3%) developed csFN including 14 (10.9%) with dFN. Multivariate analysis revealed that older age (OR 3.57, CI 1.27-10.1, P = 0.016) and living alone (OR 5.17, 95% CI 1.26-21.3, P = 0.023) were statistically significant risk factors for csFN development. As to dFN, no statistically significant risk factors were identified.
Conclusions: Older age and living alone are significant risk factors for developing FN, and thus, particularly for patients with risk factors for FN, G-CSF should be considered instead of prophylactic antibiotics with careful observation.
