Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The patients were randomly divided into PTC drug sensitivity test group and control group. The PTC drug sensitivity test group selected the adjuvant chemotherapy scheme according to the 3D drug sensitivity test results of micro tumor (PTC) in vitro. The control group made adjuvant chemotherapy strategy according to clinical experience. All exon (WES) data collection was used to predict postoperative survival in both groups.
The primary endpoint was the non inferiority test, and the 3-year disease-free survival rate was T-C \>- Δ
