What this trial studies

This study evaluates the diagnostic efficacy of 68Ga-MY6349 PET/CT imaging in patients with tumors of epithelial origin. It employs an autocontrol approach, enrolling 40 patients who will undergo both 68Ga-MY6349 and 68Ga-PSMA/18F-FDG PET/CT scans. The goal is to compare the effectiveness of these imaging techniques in diagnosing, staging, and monitoring tumor recurrence, using pathological findings as the gold standard for assessment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with pathologically confirmed tumors of epithelial origin who are scheduled for surgical resection.

Not a fit: Patients with a history of hypersensitivity to the imaging agents or those who have received prior anti-tumor therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of diagnosing and monitoring epithelial tumors, leading to better patient outcomes.

How similar studies have performed: While this approach is innovative, similar studies using PET/CT imaging have shown promise in improving diagnostic accuracy for various tumors.
