Photon-counting CT to improve tumor targeting and dose accuracy in personalized radiotherapy (ANTHEM)

Official title: Exploring Photon-Counting CT for Enhanced Target Delineation and Dose Accuracy in Personalized Radiotherapy - ANTHEM

Run by Istituto Clinico Humanitas · NCT07098247 · Data updated 2026-11-12

This project will test whether photon-counting CT can help doctors better define tumor borders and calculate radiation doses for adults receiving high-precision radiotherapy.

Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with tumors in anatomically challenging regions (brain, head and neck, liver, pancreas, prostate) or patients with cardiac disease requiring photon or proton radiotherapy at the enrolling center are ideal candidates.

Probably not a fit

Children and patients treated outside the enrolling hospital, as well as those with tumors in straightforward locations where standard imaging is already sufficient, are unlikely to receive direct benefit from this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational imaging protocol uses photon-counting CT (PCCT) during radiotherapy planning to obtain higher-resolution, spectrally enriched images for patients with challenging tumor locations or who require cardiac-directed radiation. Images and derived tissue-characterization data will be compared with conventional planning information to examine differences in target delineation and dose calculations. The study enrolls adults treated with photon or proton radiotherapy at the enrolling center and collects imaging and dosimetric metrics without changing the prescribed therapy. Results will inform whether PCCT-derived information could be incorporated into routine radiotherapy workflows for more precise planning.

Why it matters

Potential benefit: If successful, using PCCT could lead to more accurate tumor targeting and reduced radiation exposure to nearby healthy tissues.

How similar studies have gone: Early technical and pilot clinical work has shown that PCCT improves image resolution and tissue contrast, but strong evidence that it improves radiotherapy outcomes is still limited.
