Port-Site Metastasis Identified on Prostate-Specific Membrane Antigen–Targeted 18F-DCFPyL PET/CT After Robot-Assisted Laparoscopic Radical Prostatectomy
Bibliographic record
Abstract
ABSTRACT: Port-site metastasis is an extremely rare complication following minimally invasive oncologic surgery for prostate cancer. We present the case of a 74-year-old man who underwent robot-assisted laparoscopic radical prostatectomy followed by salvage radiotherapy. Despite treatment, he developed biochemical recurrence. However, there was no evidence of disease on CT and bone scan at a prostate-specific antigen of 4.6 ng/mL. Subsequently, 18 F-DCFPyL PET/CT revealed a solitary focus of intense uptake in the right rectus abdominis muscle that was felt to represent a port-site metastasis. Histopathologic evaluation with immunostaining following ultrasound-guided needle biopsy confirmed the presence of metastatic adenocarcinoma of the prostate.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
