The Role of 18F-FDG & 68Ga-FAPI PET/CT in the Assessment of Conversion Therapy Efficacy in Gastric Cancer with Peritoneal Metastatic

Обзор

This study aims to investigate the value of 18F-FDG\&68Ga-FAPI PET/CT in evaluating the outcome of conversion therapy and the prognosis of people with peritoneal metastases from gastric cancer.

Подробное описание

If the target population of the study agrees to participate in the study, we will number the participants, resume their pathology files, and collect their gender, age, phone number, height and weight information, record the participants\' consultation process and the results of the tests and examinations therein. During the course of the study we will perform 18F-FDG \& 68Ga-FAPI PET/CT according to the participant\'s stage of disease, specifically: one 18F-FDG PET/CT prior to conversion therapy and one 68Ga-FAPI PET/CT as a baseline assessment. One 18F-FDG PET/CT and one 68Ga-FAPI PET/CT were performed before the clinician assessed that the conversion therapy was ready to be completed and the conversion surgery was about to be performed, and if the participant experienced a postoperative recurrence of the disease during the study period, another 18F-FDG PET/CT and a 68Ga-FAPI PET/CT would be performed, meaning that a total of 4 PET/CTs were performed. In other words, a total of 4 PET/CT visualizations were required for all participants; 2 additional PET/CT visualizations, including 18F-FDG PET/CT and 68Ga-FAPI PET/CT, were performed if the disease recurred after the conversion surgery, and none were required for participants without recurrence.
