Radiation segmentectomy with Y-90 resin microspheres for liver tumors

Official title: RAdiation SEgmentectomy With REsin Microspheres (RASEREM) Study

Run by Ankara University · NCT07345247 · Data updated 2026-11-12

This will test whether injecting Y-90 resin microspheres into the tumor-bearing part of the liver is safe and can shrink tumors in adults with liver cancer.

Is this trial a fit for you?

Likely a good fit

Adults (≥18) with HCC or liver metastases who have one to three tumors confined to the same or neighboring liver segments, tumor size under 8 cm, Child–Pugh score below B9, and who can attend follow-up visits are ideal candidates.

Probably not a fit

Patients with macrovascular invasion, disease outside the liver, cholangiocarcinoma or mixed HCC‑cholangiocarcinoma, or those unable/unwilling to attend follow-up are unlikely to 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 is a multicenter prospective observational registry of adults with hepatocellular carcinoma or liver metastases treated with selective Y-90 resin microsphere infusion to the tumor-bearing hepatic segment. Teams will record administered dose, liver function, imaging responses, and adverse events at scheduled follow-up visits to determine safety and to describe dose thresholds linked to complete radiologic response. The main analysis will relate segmental radiation dose to rates of complete response, local control, and treatment-related toxicity. Data from participating centers in Adana, Turkey will be pooled to produce practical dose recommendations for resin microsphere segmentectomy.

Why it matters

Potential benefit: If successful, the study could define safe and effective dose limits for Y-90 resin segmentectomy and help doctors use this treatment more confidently.

How similar studies have gone: Existing evidence using glass microspheres shows strong safety and efficacy for radiation segmentectomy and retrospective reports suggest resin microspheres can work at lower doses, but prospective multicenter data for resin devices are limited.
