Imaging PD-L1 Expression in Cancers Using 68Ga-NK224 PET

68Ga-NK224 PET Imaging of PD-L1 Expression in Cancers

Observational The First Affiliated Hospital of Xiamen University · NCT06754345

This study is testing a new type of PET scan to see if it can accurately measure a protein in cancer tumors for people who have just been diagnosed or have already been treated for cancer.

What this trial studies

This study evaluates the effectiveness of 68Ga-NK224 positron emission tomography/computed tomography (PET/CT) in assessing PD-L1 expression in cancerous tumors. Participants with newly diagnosed or previously treated malignant tumors will undergo PET/CT scans, and the results will be compared to histopathological findings to determine the diagnostic accuracy. The study aims to quantify tumor uptake using maximum and mean standard uptake values (SUVmax and SUVmean).

Who should consider this trial

Good fit: Ideal candidates include adult patients aged 18 or older with newly diagnosed or previously treated malignant tumors scheduled for 68Ga-NK224 PET/CT scans.

Not a fit: Patients with non-malignant lesions or those unable to provide informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the accuracy of cancer diagnosis and treatment planning by providing reliable information on PD-L1 expression.

How similar studies have performed: While this specific approach is novel, similar imaging techniques have shown promise in evaluating tumor markers in other studies.
