Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Standardized Uptake Value (SUV), Tumor Volume (TV), Total Lesion FAP Activity (TLFAP), Tumor-to-Liver Ratio (TLR), Tumor-to-Right Gluteus Maximus Ratio (TBR);Clinical Staging Value: T staging, N staging, M staging (sensitivity, specificity, accuracy, positive predictive value, negative predictive value);Treatment Response Assessment: Pathological Response (MPR/pCR);Prognostic Prediction: Overall Survival (OS), Progression-Free Survival (PFS);Correlation Metrics: Correlation between primary tumor FAPI uptake parameters (SUVmax, SUVpeak) and pathological T staging; correlation between regional lymph node FAPI uptake parameters and pathological N staging or lymph node metastatic burden; correlation between distant metastasis and baseline highest FAPI uptake (e.g., maximum whole-body SUVmax) or FAPI uptake parameters in specific organs (e.g., liver, peritoneum);Treatment Response Prediction Model Parameters: Baseline PET parameters (SUVmax, TV, TLFAP), ?PET parameters (e.g., ?%SUVmax), clinical-pathological factors (tumor location, differentiation grade, baseline CEA/CA19-9, etc.);Risk Stratification System: Risk score formula constructed based on independent prognostic factors identified by Cox multivariate analysis (low, intermediate, high-risk groups); | — |
