Imaging Efficacy of [F]CTT1057 PET/CT in Patients with Biochemically Recurrent Prostate Cancer: Results from GuidePath-A Phase 3, Prospective Multicenter Study.

Improved diagnostic accuracy in patients with prostate cancer at first biochemical recurrence (BCR) with low prostate-specific antigen (PSA) levels is needed. This prospective study (GuidePath; NCT04838613) aimed to evaluate the imaging performance of the prostate-specific membrane antigen (PSMA)-targeted PET radiotracer [F]CTT1057 to detect PSMA-positive lesions in patients diagnosed predominantly at first BCR. Eligible patients had a PSA of 0.

Mediastinal Recurrence of Uterine Cervix Cancer on 18F-FDG PET/CT.

We report the case of a 64-year-old woman with a mediastinal relapse of a uterine cervix cancer with positive human papillomavirus, an unusual site of recurrence. She consulted because of solid and liquid dysphagia of sudden appearance. Endoscopic study and non-contrast-enhanced CT showed intraluminal esophageal stenosis with a retrograde esophageal distension.
