Neutrophil count kinetics during the first cycle of chemotherapy predicts the outcome of patients with locally advanced or metastatic pancreatic cancer.

Abstract:

BACKGROUND:Neutrophil count reduction after chemotherapy has been related with longer survival of patients with metastatic pancreatic adenocarcinoma, but there is not a standardized measurement for this phenomenon. METHODS:Some parameters related to the change in neutrophil count between the first and the second cycle of chemotherapy or between the baseline count and the nadir have been evaluated among patients with advanced pancreatic cancer at a single institution. A Cox regression model was built which included, in addition to the common prognostic variables, some variables related to the change of the neutrophil count after chemotherapy. RESULTS:One hundred patients were selected. Two neutrophil kinetics related variables predicted overall survival independently, such as the neutrophil count growth rate (hazard ratio [HR] = 1.245; confidence intervals [CIs], 1.077-1.440) and the chemotherapy-induced neutropenia after one cycle (HR = 0.499; CIs, 0.269-0.927). CONCLUSION:The kinetics of neutrophil count after chemotherapy is an early and independent prognostic factor, which appears to be simple to measure at the start of the second cycle of chemotherapy by means of the neutrophil count growth rate.
