In the post-genomic era,with the advancement of molecular pathological detection techniques,the mode of tumor prevention,diagnosis and treatment has changed dramatically.Molecular pathological detection techniques has been more and more used in the whole course management of solid tumors,and has become critical for promoting the overall survival of patients with solid tumors.In recently years,molecular pathological testing represented by next generation sequencing(NGS)has played key roles in identification of genetic susceptibility genes,early detection of solid tumors and development of personalized therapeutic strategies for malignant solid tumors.This review briefly introduces the real world application of different molecular pathological testing platforms in different stages of tumor prevention and management as well as the potential problems.
