## TL;DR

Fluciclovine F-18 was the first PET tracer approved for finding recurrent prostate cancer after treatment (2016), and has been largely superseded since 2020 by PSMA PET.

## Summary

Approved May 2016 for suspected recurrence with rising PSA; detection ~68% overall, lower at low PSA. EMSPOT/EMPIRE-1 (Lancet 2021) showed fluciclovine-guided salvage radiotherapy improved failure-free survival. PSMA PET (Ga-68 PSMA-11, piflufolastat, flotufolastat) has higher detection and displaced it.

## Fields

- Kind: Agent
- Status: approved
- Last checked: 2026-09-08
- Tags: gap-fill; diagnostic
- Brand: Axumin
- Modality: PET radiotracer (synthetic amino acid)
- Mechanism: 18F-labelled leucine analogue taken up via LAT1/ASCT2 amino-acid transporters upregulated in prostate cancer; low urinary excretion improves pelvic imaging.
