Area of Science:

Oncology
Medical Physics

Background:

High-dose chemotherapy can cause severe side effects.
Preventing drug penetration into the main circulation is crucial.
Current leakage detection relies on radionuclide tracing.

Purpose of the Study:

To develop a method for continuous, real-time monitoring of fluid leakage during chemotherapy perfusion.
To enable surgical oncologists to reliably detect and quantify drug crossover into the main circulation.

Main Methods:

A novel method continuously calculates the volume of perfusate leaking into the main circulation.
Utilizes scintillation probes to track radionuclide distribution.
Provides real-time data on momentary and cumulative volume crossover.

Offers reliable and immediate detection of leakage.
Enables quantification of both momentary and cumulative volume crossover.

Conclusions:

The developed method provides a reliable tool for monitoring chemotherapy leakage.
Facilitates timely intervention to confine drug crossover.
Aims to reduce side effects associated with high-dose chemotherapy.
