Abstract

The individualization of cytostatic agent dose is an actual problem in isolated lung chemoperfusion (ILP). Hitherto it has been carried out according to anthropometric data, in particular, the surface area of the body. A biophysical model of ILP based on diffusion cisplatin transfer in the lung is proposed. The model indicates to get the individual drug dose according to physical lung volume, which can be measured by CT-volumetry. Cisplatin pharmacokinetics and model compliance with actual data are considered on the material of 28 ILP. Estimates of lung interstitial and vascular space volumes and diffusion characteristic of capillary membrane are obtained.
