Clinical Trial: Clinical Study of Pretreatment PET/CT Parameters for Predicting the Efficacy of 125I Seed Implantation in the Treatment of Malignant Tumors

U.S., Oct. 7 -- ClinicalTrials.gov registry received information related to the study (NCT07208487) titled 'Clinical Study of Pretreatment PET/CT Parameters for Predicting the Efficacy of 125I Seed Implantation in the Treatment of Malignant Tumors' on Sept. 27.

Brief Summary: This study aimed to determine if pre-treatment 18F-FDG PET/CT metabolic parameters could predict the effectiveness of 125I seed implantation for malignant tumors. In a retrospective analysis of 41 patients with 69 lesions, various parameters were measured. The results identified Metabolic Tumor Volume (MTV) as the most significant independent prognostic factor, outperforming other standardized uptake values (SUV) and ratios. A higher MTV was associated with a worse tr...
