Sarcoma drug resistance is complex, involving molecular and microenvironmental factors. Precision medicine strategies, combining mechanistic insights with biomarker-guided therapies, offer a promising approach to improve patient outcomes.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Sarcomas exhibit multifaceted drug resistance.
- Understanding resistance mechanisms is crucial for effective treatment.
Purpose of the Study:
- To systematically review sarcoma drug resistance mechanisms.
- To evaluate precision medicine strategies against these mechanisms.
Main Methods:
- Comprehensive literature review of sarcoma, drug resistance, and precision medicine.
- Categorization of resistance pathways and therapeutic countermeasures.
Main Results:
- Key resistance drivers include ABC transporters, DNA repair, secondary mutations, and immune evasion.
- Emerging strategies involve next-generation TKIs, dual-pathway inhibitors, and chemo-immuno combinations.
- Liquid biopsies (ctDNA) aid resistance monitoring.
Conclusions:
- Integrating multi-omics, liquid biopsies, and organoids can personalize sarcoma therapy.
- Biomarker-guided combination/sequential therapies are vital for overcoming resistance.
