Tyrosine kinase inhibitors (TKIs) show promise in treating osteosarcoma (OS) by improving progression-free survival. However, acquired drug resistance remains a significant challenge, necessitating further research into overcoming this limitation for better patient outcomes.
Area of Science:
- Oncology
- Pharmacology
- Biomedical Research
Background:
- Osteosarcoma (OS) is the most common primary malignant bone tumor.
- While survival rates improved with chemotherapy and resection, progress has stagnated.
- Tyrosine kinase inhibitors (TKIs) offer potential but face challenges in advanced OS.
Purpose of the Study:
- To review the applications of TKIs in osteosarcoma.
- To elucidate the mechanisms of TKI resistance in OS.
- To explore strategies for overcoming TKI resistance in OS treatment.
Main Methods:
- Literature review of TKI applications in OS.
- Analysis of TKI resistance mechanisms.
- Examination of strategies to overcome TKI resistance.
- Inclusion of data from animal, cell models, clinical trials, and bioinformatics.
Main Results:
- TKIs improve progression-free survival in advanced OS but not overall survival.
- Acquired drug resistance is a primary reason for unchanged overall survival.
- Understanding TKI resistance mechanisms and solutions is crucial but limited.
Conclusions:
- TKIs represent a novel therapeutic avenue for osteosarcoma.
- Addressing TKI resistance is critical for improving patient outcomes.
- Further research integrating preclinical and clinical data is needed.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
