Background: Nitrogen-containing bisphosphonates (N-BPs) have been designed to inhibit osteoclast-mediated bone resorption. However, it is now accepted that part of their anti-tumor activities is related to interference with the mevalonate pathway.

This model can be used to describe both the duration and intensity of neutropenia; the area between the curve of neutrophil count versus time and a critical neutrophil count (such as 0.500 x 10(3) /mm 3 ) would be a better toxic endpoint than the unique observed value of neutrophil at nadir. The model may be used to predict neutropenia corresponding to regimens of topotecan not yet explored.
