Drug sensitivity is typically evaluated through in vitro and in vivo methods. In vitro assays involve culturing cancer cells and treating them with drugs to measure their viability. Techniques like cell viability assays, flow cytometry, and imaging are commonly used. In vivo methods often involve animal models where tumor growth and response to treatment are monitored. Additionally, genomic profiling and biomarker analysis are increasingly being used to predict drug sensitivity based on the molecular characteristics of the tumor.
