What this trial studies

This observational study aims to evaluate the therapeutic efficacy of 18F-FDG combined with 18F-FAPI PET/MR imaging in patients with primary gastric adenocarcinoma undergoing neoadjuvant therapy. It will involve collecting clinical data, performing imaging assessments, and analyzing pathological specimens to determine the effectiveness of the imaging techniques in staging and treatment response. The study will take place at Daping Hospital from January 2024 to January 2026, focusing on patients who have undergone surgical resection after neoadjuvant treatment. Statistical analyses will be conducted to compare imaging results and clinical outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older diagnosed with primary gastric adenocarcinoma who are eligible for neoadjuvant therapy and surgical resection.

Not a fit: Patients with severe comorbidities, poor imaging quality, or those who are pregnant or lactating may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the accuracy of staging and treatment response assessment in gastric cancer, potentially leading to improved surgical outcomes.

How similar studies have performed: While the use of PET/MR imaging in cancer treatment is gaining traction, this specific combination in the context of gastric cancer neoadjuvant therapy is relatively novel and has not been extensively tested.
