Next-generation sequencing (NGS) technologies, widely used in cancer research, generate vast and diverse data that require sophisticated computational methods and bioinformatics expertise. This review provides background details of NGS technology and basic bioinformatics concepts for clinicians interested in cancer research applications, with a focus on DNA-based approaches. It introduces principles of library preparation, alignment, variant calling, variant annotations, and NGS applications for other molecular data types. The review also discusses the utility of NGS methods in NSCLC research and study design considerations for leveraging NGS technologies in clinical care.
Next-generation sequencing (NGS) technologies are high -throughput methods for DNA sequencing and have become a widely adopted tool in cancer research. The sheer amount and variety of data generated by NGS assays require sophisticated computational methods and bioin-formatics expertise. In this review, we provide background details of NGS technology and basic bioinformatics concepts for the clinician investigator interested in cancer research applications, with a focus on DNA-based approaches. We introduce the general principles of presequencing library preparation, postsequencing alignment, and variant calling. We also highlight the common variant annotations and NGS applications for other molecular data types. Finally, we briefly discuss the revealed utility of NGS methods in NSCLC research and study design considerations for research studies that aim to leverage NGS technologies for clinical care.
