Evaluation of [18F]AlF-NOTA-PCP2 PET/CT for PD-L1 Detection in Malignant Tumors

Overview

This phase I/II clinical trial evaluates the safety, efficacy, and prognostic potential of \[18F\]AlF-NOTA-PCP2 PET/CT imaging in assessing PD-L1 expression in malignant tumors, including glioblastoma, head and neck squamous cell carcinoma, non-small cell lung cancer, and esophageal cancer. The primary aim is to establish the correlation between \[18F\]AlF-NOTA-PCP2 uptake and PD-L1 expression in tumor tissues, while secondary objectives include evaluating its role in predicting clinical outcomes such as progression-free survival (PFS) and overall survival (OS). By providing a non-invasive, quantitative, and reproducible method for assessing PD-L1, this study aims to refine patient stratification and improve the precision of immunotherapy decision-making.
