What this trial studies

This study aims to assess the effectiveness of 68Ga-FAPI-04 and 18F-FDG PET/CT imaging in predicting the response to neoadjuvant chemotherapy in patients with locally advanced gastric cancer. Patients will undergo baseline PET/CT scans before starting chemotherapy, followed by treatment and subsequent imaging after one cycle or before surgery. The imaging results will be compared to the histopathological tumor regression grade from surgical specimens to determine the accuracy of these imaging techniques in evaluating treatment response.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18-75 with histologically confirmed resectable gastric adenocarcinoma and a good performance status.

Not a fit: Patients with second primary malignancies, severe comorbid conditions, or known hypersensitivity to chemotherapy drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate predictions of chemotherapy efficacy, allowing for personalized treatment plans for patients with gastric cancer.

How similar studies have performed: While the use of PET/CT imaging in cancer treatment evaluation is established, this specific approach in gastric cancer is novel and has not been extensively tested.
