What this trial studies

This study investigates the safety and feasibility of two specific PET/CT imaging agents, [68Ga]Ga-NOTA-WWH347 and [18F]F-H3RESCA-WWH347, in patients with primary and metastatic colorectal cancers. The study aims to evaluate the diagnostic efficacy of these imaging agents, focusing on their sensitivity and specificity. By providing a noninvasive, target-specific method for diagnosing colorectal cancer, this research seeks to enhance clinical diagnosis, differential diagnosis, and treatment planning.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 65 with confirmed colorectal cancer.

Not a fit: Patients with severe hepatic or renal insufficiency or those who have undergone targeted therapy prior to the imaging may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic accuracy for colorectal cancer, facilitating earlier and more effective treatment.

How similar studies have performed: While this approach is innovative, similar studies using PET/CT imaging for cancer diagnosis have shown promising results.
