Predictors of severe and febrile neutropenia during primary chemotherapy for ovarian cancer.

Journal Article

OBJECTIVE: To identify factors that increase the risk of neutropenic events in women with advanced ovarian carcinoma receiving initial chemotherapy. METHODS: Multi-center retrospective study of women with FIGO stage III-IV epithelial ovarian cancer treated postoperatively with multi-agent intravenous chemotherapy from 1995 to 2008. Outcomes were severe (SN; absolute neutrophil count [ANC]<500/mm(3)) and febrile neutropenia (FN; ANC<1000/mm(3) and temperature>38.1°C). Cumulative risk of neutropenic events was estimated by Kaplan Meier method. Multivariate analysis was by Cox proportional hazard regression. RESULTS: Three hundred twenty-six patients met inclusion criteria. There were 251 SN events among 140 (43%) patients and 24 FN events among 22 (7%) patients. Univariate predictors of SN were body surface area<2.0m(2) (p=0.03), body mass index (BMI)<30 kg/m(2) (p<0.01), Caucasian race (p<0.01), treatment on research protocols (p<0.01), non-carboplatin-containing regimens (p<0.01), and planned relative dose intensity (RDI)>85% of standard (p=0.02). Women over age 60 were more likely to develop FN (p=0.05). Multivariate predictors of SN were treatment on research protocols (hazard ratio [HR] 1.93; p<0.01), Caucasian race (HR 2.13; p=0.01), and planned RDI>85% (HR 1.69; p=0.05); predictors of FN were age>60 (HR 2.84; p=0.05) and non-carboplatin containing regimens (HR 4.06; p<0.01). CONCLUSION: While SN is fairly common, FN occurs infrequently in women with EOC undergoing taxane and platin-based chemotherapy and primary prophylactic growth factor support is not indicated. However, women older than 60 years of age receiving non-carboplatin containing regimens are at higher risk for FN and warrant closer surveillance.
