Precision medicine for gastrointestinal cancer:Recent progress and future perspective

更新时间:2023-05-28

【摘要】Gastrointestinal(GI) cancer has a high tumor incidence and mortality rate worldwide.Despite significant improvements in radiotherapy,chemotherapy,and targeted therapy for GI cancer over the last decade,GI cancer is characterized by high recurrence rates and a dismal prognosis.There is an urgent need for new diagnostic and therapeutic approaches.Recent technological advances and the accumulation of clinical data are moving toward the use of precision medicine in GI cancer.Here we review the application and status of precision medicine in GI cancer.Analyses of liquid biopsy specimens provide comprehensive real-time data of the tumor-associated changes in an individual GI cancer patient with malignancy.With the introduction of gene panels including next-generation sequencing,it has become possible to identify a variety of mutations and genetic biomarkers in GI cancer.Although the genomic aberration of GI cancer is apparently less actionable compared to other solid tumors,novel informative analyses derived from comprehensive gene profiling may lead to the discovery of precise molecular targeted drugs.These progressions will make it feasible to incorporate clinical,genome-based,and phenotype-based diagnostic and therapeutic approaches and apply them to individual GI cancer patients for precision medicine.
