Research Article: Exploring the Association Between PRC Genes Variants and Lung Cancer Risk in Chinese Han Population
Abstract:
Lung cancer (LC) is a highly prevalent malignancy worldwide and stands as the foremost cause of cancer-related mortality. The five-year survival rate of LC remains dishearteningly low, hovering around %. Histologically, LC is categorized into small-cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). SCLC accounts for approximately %–% of LC cases, while NSCLC encompasses about %–% of cases, including adenocarcinoma, squamous cell carcinoma, and more rarely, large cell lung cancer. Certain subtypes of LC, such as squamous cell carcinoma and SCLC, are primarily associated with the most significant risk factor—cigarette smoking. Tobacco smoke consists of over chemicals, including more than known or suspected carcinogens.,. However, a recent report from the United States has indicated a higher incidence of LC among young women compared to young men, implying that smoking alone does not entirely account for the occurrence of LC. In addition to active smoking, other risk factors, including passive smoking, radon exposure, and dust pollution, can contribute to LC., Moreover, genetic factors also influence the incidence of this disease. In this regard, it has been shown that variations at specific gene site can elevate the risk of developing LC in carriers. In recent years, exploration of the molecular atlas of LC has enhanced our comprehension of its occurrence and progression, offering valuable guidance for targeted therapies. Targeted therapies, such as those directed against EGFR, KRAS, and BRAF mutations or amplifications, and ALK alterations, which have significantly improved the prognosis of patients with advanced LC.,
