Abstract:
The shift in cancer therapy from broadly cytotoxic agents toward "personalized" treatments that target specific alterations in each patient's tumor requires diagnostic pathology approaches that are quantitative and biospecimen-friendly. Novel multiplexed antibody-based imaging technologies can measure single-cell expression of over 60 proteins in intact tumor sections and hold promise for clinical oncology.
Insights
Personalized cancer therapies need better diagnostics. Multiplexed antibody imaging offers a new way to analyze single cells in tumors for more precise treatment.
Area of Science:
- Oncology
- Pathology
- Biotechnology
Background:
- Cancer therapy is shifting towards personalized treatments targeting specific tumor alterations.
- Current diagnostic pathology methods need to be quantitative and biospecimen-friendly to support this shift.
Purpose of the Study:
- To introduce novel multiplexed antibody-based imaging technologies for cancer diagnostics.
- To highlight the potential of these technologies in clinical oncology.
Main Methods:
- Utilizing multiplexed antibody-based imaging.
- Measuring single-cell protein expression in intact tumor sections.
- Analyzing over 60 proteins simultaneously.
Main Results:
