Abstract
e12523 Background: Neutropenia and febrile neutropenia are major dose-limiting adverse effects of systemic cancer chemotherapy. It has been associated with significant morbidity and mortality, and high costs of management, and treatment breaks in cancer patients especially in resource-limited environments leading to poorer outcomes. Chemotherapy-induced neutropenia is an established complication of breast cancer treatment, however, there is paucity of information on the exact magnitude of the condition. This study assessed the prevalence of neutropenia and febrile neutropenia, while identifying their associated factors. Methods: A cross-sectional study was conducted among 113 female chemotherapy-naïve breast cancer patients over a two-year period. Sociodemographic, clinical and haematological data was obtained via semi-structured interviews and from medical case files. Blood samples for complete blood count parameters were collected after each course of chemotherapy. The National Cancer Institute Common Terminology CTCAE version 4.03 was used to assess febrile neutropenia, neutropenia and its severity. Results: The prevalence of neutropenia and febrile neutropenia among the patients was 31.9% and 5.3% respectively. Throughout all courses of chemotherapy, there were neutropenic episodes 11.4% (57/502) with mild neutropenia 6.6%, moderate 3.4% and severe 1.4%. Prevalence of neutropenia decreased with increasing chemotherapy courses, with prevalence after first course being 14.2% and last course 4.9%. Associated risk factors for developing neutropenia include increasing age ( p = 0.014), ECOG performance score > 1 at presentation (p = 0.033) and presence of bone metastasis (p = 0.002). Conclusions: One in three breast cancer patients developed neutropenia while on chemotherapy. The use of prophylactic G-CSF after each course of chemotherapy should be a routine practice, especially among elderly patients, unstable patients, and those with bone metastasis.
