Abstract:
Precision medicine approaches have revolutionized oncology. Personalized treatments require not only identification of the driving molecular alterations, but also development of targeted therapies and diagnostic tests to identify the appropriate patient populations for clinical trials and subsequent therapeutic implementation. Preclinical in vitro and in vivo models are widely used to predict efficacy of newly developed treatments. Here we discuss whether, and to what extent, preclinical models including cell lines, organoids and tumorgrafts recapitulate key features of human tumors. The potential of preclinical models to anticipate treatment efficacy and clinical benefit is also presented, using examples in different tumor types.
Insights
Precision medicine in oncology relies on preclinical models to predict treatment efficacy. This review examines how well cell lines, organoids, and tumorgrafts mimic human tumors and anticipate clinical benefit.
Area of Science:
- Oncology
- Translational Medicine
- Cancer Research
Background:
- Precision medicine has transformed cancer treatment by tailoring therapies to individual molecular profiles.
- Accurate prediction of treatment efficacy requires robust preclinical models.
- Identifying suitable patient populations for clinical trials is crucial for therapeutic development.
Purpose of the Study:
- To evaluate the extent to which preclinical models recapitulate human tumor features.
- To assess the predictive value of these models for treatment efficacy and clinical benefit.
- To provide examples across different tumor types.
Main Methods:
- Review of existing literature on preclinical cancer models.
- Analysis of studies comparing preclinical models (cell lines, organoids, tumorgrafts) to human tumors.
- Examination of data correlating preclinical model predictions with clinical outcomes.
Main Results:
- Preclinical models exhibit varying degrees of fidelity in recapitulating human tumor characteristics.
- Certain models, like organoids and tumorgrafts, show higher potential for predicting treatment response than traditional cell lines.
- Examples demonstrate the utility and limitations of these models in anticipating therapeutic success.
Conclusions:
- Preclinical models are essential but imperfect tools in precision oncology.
- Model selection should be guided by the specific research question and tumor type.
- Further development is needed to enhance the predictive accuracy of preclinical models for clinical benefit.
