Lung cancer remains one of the leading causes of cancer-related deaths worldwide, largely due to its late diagnosis and complex pathogenesis. Emerging evidence highlights the critical role of DNA repair genes in the development and progression of lung cancer. These genes are essential for maintaining genomic stability by correcting DNA damage caused by various factors, including environmental carcinogens. This article explores the role of DNA repair genes in lung cancer, focusing on their mechanisms, impact on disease progression, and potential for targeted therapies. DNA repair genes are involved in several key mechanisms that correct DNA damage and maintain genomic integrity. Several DNA repair genes have been implicated in lung cancer, and their alterations can influence disease risk and progression: Lung cancer is strongly associated with exposure to environmental carcinogens, particularly tobacco smoke, which contains numerous DNAdamaging agents. Tobacco carcinogens can induce mutations in DNA repair genes, impairing their function. These impairments can lead to the accumulation of DNA damage and increased cancer risk. Genetic variants in DNA repair genes can affect an individual’s susceptibility to lung cancer. For example, polymorphisms in OGG1 and XRCC1 have been associated with increased lung cancer risk. These variants can impact the efficiency of DNA repair processes and contribute to carcinogenesis. Targeting DNA repair pathways offers a promising approach for lung cancer treatment. For instance, inhibitors of poly(ADP-ribose) polymerase, an enzyme involved in DNA repair, are being investigated for their efficacy in treating lung cancer with DNA repair defects. PARP inhibitors can exploit the synthetic lethality of DNA repair deficiencies, selectively targeting cancer cells with impaired repair mechanisms. Integrating knowledge of DNA repair gene alterations into personalized medicine can enhance treatment strategies. By characterizing the specific DNA repair defects present in a patient’s tumor, clinicians can tailor therapies to address these vulnerabilities. Personalized approaches may involve combining DNA repair inhibitors with conventional treatments to improve therapeutic outcomes. Ongoing research is focused on several areas to advance our understanding of DNA repair genes in lung cancer: Further research is needed to elucidate the precise mechanisms by which DNA repair gene alterations contribute to lung cancer development and progression. Understanding these mechanisms can inform the development of more targeted therapies. Identifying new therapeutic targets within DNA repair pathways and developing novel inhibitors or modulators could enhance treatment options for lung cancer patients. Research into the interactions between DNA repair genes and other cancer-related pathways may reveal additional targets for intervention. Exploring combination therapies that integrate DNA repair inhibitors with other treatment modalities, such as immunotherapy or targeted therapy, may improve treatment efficacy and overcome resistance mechanisms. In conclusion, DNA repair genes play a crucial role in the development and progression of lung cancer by maintaining genomic stability and responding to DNA damage. Alterations in these genes can influence susceptibility to lung cancer and impact tumor behavior. Understanding the role of DNA repair mechanisms in lung cancer has significant implications for diagnosis, treatment, and personalized medicine. As research progresses, targeted therapies and novel approaches based on DNA repair gene profiles hold promise for improving outcomes for lung cancer patients.
