简要总结
This study intends to explore the value of 68Ga-FAPI-04 and 18F-FDG PET/CT in the evaluation of treatment response to neoadjuvant chemotherapy(NAC) for patients with locally advanced gastric cancer(LAGC).
详细描述
Before the start of NAC, baseline 68Ga-FAPI-04 PET/CT and 18F-FDG PET/CT scans will be scheduled in all enrolled patients. Next, the patients with resectable LAGC will receive NAC treatment, surgery will follow 3~6 weeks after finishing NAC. Abdomen 68Ga-FAPI-04 PET/CT and 18F-FDG PET/CT will be scheduled after one cycle of NAC treatment or before surgery. Imaging response measurements will be compared with the histopathological tumor regression grade (TRG) of the resection specimen as gold standard.
