Diagnosis and treatment of lung cancer: A molecular perspective.

Abstract

This editorial comments on the review by Da Silva et al, published in the World Journal of Clinical Oncology which focuses on the molecular perspectives of lung cancer. With the rapid development of molecular technology, new diagnostic methods are constantly emerging, including liquid biopsy, the identification of gene mutations, and the monitoring biomarkers, thus providing precise information with which to identify the occurrence and development of lung cancer. Biomarkers, such as circulating tumor cells, circulating tumor DNA, and circulating RNA can provide helpful information for clinical application. Common types of genetic mutations and immune checkpoints include epidermal growth factor receptor, anaplastic lymphoma kinase, c-ROS proto-oncogene 1, programmed death-1 and cytotoxic T-lymphocyte-associated protein. According to specific biomarkers, targeted therapy and immunotherapy can improve survival outcomes based on the types of gene mutation and immune checkpoints. The application of molecular approaches can facilitate our ability to control the progression of disease and select appropriate therapeutic strategies for patients with lung cancer.
