Abstract:
Cancer treatments utilizing biologic or cytotoxic drugs compose the frontline of therapy, and though gains in treatment efficacy have been persistent in recent decades, much work remains in understanding cancer progression and treatment. Compounding this situation is the low rate of success when translating preclinical drug candidates to the clinic, which raises costs and development timelines. This underperformance is due in part to the poor recapitulation of the tumor microenvironment, a critical component of cancer biology, in cancer model systems. New technologies capable of both accurately observing and manipulating the tumor microenvironment are needed to effectively model cancer response to treatment. In this review, conventional cancer models are summarized, and a primer on emerging techniques for monitoring and modulating the tumor microenvironment is presented and discussed.
Insights

Area of Science:
- Oncology
- Biomedical Engineering
- Cancer Biology
Background:
- Current cancer treatments, including biologic and cytotoxic drugs, face challenges in efficacy and translation from preclinical to clinical settings.
- A key limitation in current cancer models is their inadequate representation of the tumor microenvironment, hindering accurate prediction of treatment response.
- The high cost and lengthy timelines of drug development are exacerbated by the low success rate of preclinical candidates in clinical trials.
Purpose of the Study:
- To review conventional cancer models and their limitations in recapitulating the tumor microenvironment.
- To introduce and discuss emerging technologies for observing and manipulating the tumor microenvironment.
