Abstract

This study described the characteristics and investigated several factors related to neutropenia in 118 breast cancer patients receiving chemotherapy at Hanoi Oncology Hospital (437 chemotherapy cycles). Thirty-four patients (28.8%) experienced at least one episode of neutropenia, 15 patients had severe neutropenia (12.7%), and 5 patients had complications related to neutropenia (6.0%). Univariate analysis showed that high-risk regimens significantly increased the risk of any degree of neutropenia; treatment during cycle 1 increased the rate of severe neutropenia, and renal dysfunction along with previous complications of neutropenia increased the rate of neutropenia-related complications. Patients with a history of neutropenia at any level or severe neutropenia had an increased likelihood of developing recurrent neutropenia (both any-level and severe) (p < 0,05). Multivariate analysis identified several factors that significantly increased the risk of neutropenia of any grade and severe neutropenia, including high-risk regimens, treatment in cycle 1, and a history of neutropenia in previous cycles. It is necessary to further develop a predictive model for factors increasing the risk of neutropenia to optimize prophylactic strategies for each patient based on real-world data.
