Abstract:
Osteosarcoma (OS), the most common malignant bone tumor in adolescents, exhibits marked genetic and cellular heterogeneity, contributing to its resistance to conventional therapies. Although surgical and chemotherapeutic interventions have advanced, survival rates remain stagnant, especially for patients with metastatic or treatment-refractory disease. Recent multi-omic studies have uncovered distinct molecular subtypes characterized by unique genomic, epigenomic, transcriptomic, and tumor microenvironmental signatures. The integration of bulk and single-cell transcriptomics, spatial profiling, epigenetic mapping, and proteomic analyses has provided unprecedented insights into the pathogenesis of OS and has facilitated the identification of novel biomarkers. This review comprehensively summarizes the current advances in the molecular subtyping of OS, highlighting subtype-specific oncogenic drivers, their implications in tumor progression and therapeutic resistance, and the potential for precision medicine strategies tailored to these molecular profiles.

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...
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...
