RESUMEN
The morbidity and mortality rates of lung cancer in Xuanwei city, Yunnan province, China are the highest in the global scope. Since 1980s, the studies conducted in this region supported by international health organizations have been focused on the epidemiology, pathogenesis and molecular biology of Xuanwei lung cancer. With the development of molecular detection techniques and the application of next-generation sequencing technique, great progress has been achieved in understanding the environmental risk factors which cause this disease and the improvement of diagnostic methods and therapeutic measures in Xuanwei city. This review surveys the recent development in research of lung cancer in this area from the perspectives of environmental risks, mutation and expression of cancer-related genes, and the diagnosis and drug treatment. Moreover, the positive role of next-generation sequencing technique in diagnosis and treatment of Xuanwei lung cancer will be discussed.
