Overview
The purpose of this study is to evaluate the feasibility, efficacy and safety of target therapy according to genomic and proteomic profiling combined with GEMOX in recectable gallbladder carcinoma patients monitored by ctDNA.
Description
Genomic profiling studies the deoxyribonucleic acid (DNA) of a tumor to detect genetic changes or abnormalities. immuno-histochemistry tests reveal the abnormal activation status of signal pathways involved in study. These information will be used to recommend target therapy which may be more likely to result in a beneficial response. Patients will receive target antitumor agents according to the result of genomic and proteomic profiling and be monitored by circulating tumor DNA(ctDNA).
