DNA genome sequencing in esophageal adenocarcinoma

Abstract

Next-generation sequencing refers to the high-throughput DNA sequencing technologies, which are capable of sequencing large numbers of different DNA sequences in a single/parallel reaction. It is a powerful tool to identify inherited and acquired genetic alterations associated with the development of esophageal adenocarcinoma. Whole-genome sequencing is the most comprehensive but expensive, whereas whole-exome sequencing is cost-effective but it only works for the known genes. Thus, second-generation sequencing methods can provide a complete picture of the esophageal adenocarcinoma genome by detecting and discovering different type of alterations in the cancer. This would help in diagnostics and will further help in developing personalized medicine in esophageal adenocarcinoma.
