Brief Summary:
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).

Condition or disease Intervention/treatment Phase
Gastric Cancer Diagnostic Test: 68Ga-FAPI-04 PET/CT and 18F-FDG PET/CT Not Applicable

Detailed Description:
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.

Arm Intervention/treatment
Experimental: PET/CT for prediction of NAC efficacy
68Ga-FAPI-04 PET/CT and 18F-FDG PET/CT will be scanned before, during or after NAC.
Diagnostic Test: 68Ga-FAPI-04 PET/CT and 18F-FDG PET/CT
Baseline 68Ga-FAPI-04 PET/CT and 18F-FDG PET/CT scans before NAC followed by abdomen 68Ga-FAPI-04 PET/CT and 18F-FDG PET/CT scans after one cycle of NAC treatment or before surgery.

Primary Outcome Measures :
  1. Prediction for NAC efficacy [ Time Frame: Two weeks after surgery ]
    Predictive value of 68Ga-FAPI PET/CT and 18F-FDG PET/CT for LAGC in NAC response assessment.

  2. Standardized uptake value(SUV) [ Time Frame: Two weeks after surgery ]
    SUV of 68Ga-FAPI and 18F-FDG uptake on PET/CT images for primary gastric cancer.

  3. Target-to-background ratio(TBR) [ Time Frame: Two weeks after surgery ]
    68Ga-FAPI and 18F-FDG uptake ratio of primary gastric cancer to mediastinum blood pool on PET/CT images.

Secondary Outcome Measures :
  1. Diagnostic efficacy for metastatic lymph nodes [ Time Frame: Two weeks after surgery ]
    The sensitivity, specificity, NPV, PPV and accuracy of 68Ga-FAPI PET/CT for metastatic lymph nodes in comparison with those of 18F-FDG PET/CT.

  2. Disease free survival [ Time Frame: 5 years ]
    Disease free survival

  3. Overall survival [ Time Frame: 5 years ]
    Overall survival
