Purpose:
Osteosarcoma (OS) is one of the most common primary bone tumors. Direct pathogenesis remains unknown, however, genes' mutations are proven to participate in the process. This study aimed to examine the most frequently mutated genes in OS to appoint candidates for the cancer markers.
Methods:
Using the COSMIC Catalogue twenty the most frequently mutated genes were selected leading to an up-to-date genetic OS landscape summary. The genes can be classified into four categories: suppressor genes (TP53, RB1, NCOR1, SMAD2, NF1, TSC2, KMT2C), proto-oncogenes (GNAS, BRAF, MLLT3), epigenetic and post-translational modification-related genes (SMARCA4, ARID1A, ATRX, BCOR, H3F3A) and cell growth and survival regulating genes (EGFR, CAMTA1, LRP1B, PDE4DIP, MED12).
Results And Conclusions:
Their role in cancerogenesis was confirmed by the analysis of available articles published previously. The results of the study indicate that examination of selected genes' mutations might help to identify patients' predisposition to OS development, as well as monitor the disease progression, and establish prognosis. However, to fully understand the pathogenesis of OS further studies are required.
Insights
This study identifies frequently mutated genes in osteosarcoma (OS), a common bone cancer. Analyzing these genetic mutations may help predict OS development and track disease progression.
Area of Science:
- Oncology
- Genetics
- Molecular Biology
Background:
- Osteosarcoma (OS) is a prevalent primary bone tumor with largely unknown direct pathogenesis.
- Gene mutations are recognized as key contributors to OS development.
Purpose of the Study:
- To identify frequently mutated genes in OS.
- To propose candidate genes for use as cancer markers in OS.
Main Methods:
- Utilized the COSMIC Catalogue to select the twenty most frequently mutated genes in OS.
- Classified selected genes into categories: tumor suppressor, proto-oncogene, epigenetic/post-translational modification-related, and cell growth/survival regulators.
Main Results:
- Compiled an updated summary of the genetic landscape of OS.
- Identified specific genes within each functional category, including TP53, RB1, GNAS, BRAF, SMARCA4, ARID1A, EGFR, and MED12.
Conclusions:
- Confirmed the role of these genes in cancerogenesis through literature review.
- Examining mutations in these selected genes may aid in identifying patient predisposition, monitoring disease progression, and establishing prognosis for OS.
- Further research is necessary to fully elucidate the pathogenesis of OS.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

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...
