Conditions
Summary
For patients with stage II-III gastric cancer after radical D2 resection and R0 resection, postoperative adjuvant therapy guided by ctDNA-MRD (MRD-GATE external cohort) was not inferior to the standard chemotherapy regimen (this cohort).

Aspartate or alanine aminotransferase ≤ 2.5 times the upper limit of normal. e. Alkaline phosphatase ≤ 2.5 times the upper limit of normal. f. Thyroid-stimulating hormone (TSH) ≤ 1 times the upper limit of normal (if abnormal, T3 and T4 levels must be normal).

- Positive HIV antibody, active hepatitis B or C (with specific viral load criteria).
- Positive for COVID-19 nucleic acid or antigen test.
