Targeted radiation (SBRT) after TACE for liver cancer

Adjuvant Stereotactic Body Radiation Therapy After Trans-arterial Chemoembolization in Hepatocellular Carcinoma

Not applicable Interventional RWTH Aachen University · NCT04996914

This study tests whether adding stereotactic body radiation therapy (SBRT) after trans-arterial chemoembolization (TACE) helps people with early or intermediate hepatocellular carcinoma who cannot have surgery.

What this trial studies

The trial enrolls adults with early or intermediate stage hepatocellular carcinoma (BCLC A or B) who are not candidates for surgical resection or transplant and have one to three liver lesions totaling at least 4 cm. Participants receive trans-arterial chemoembolization (TACE) followed by stereotactic body radiation therapy (SBRT) targeted to the treated lesions. Eligibility requires adequate liver reserve (Child–Pugh A5–6 or selected B7–8), sufficient non-tumor liver volume, and acceptable blood counts and kidney function, while patients with extrahepatic disease or macroscopic vascular invasion are excluded. Patients will be followed for local tumor control, liver-related toxicity, and clinical outcomes over time.

Who should consider this trial

Good fit: Adults 18–80 with 1–3 non-resectable HCC lesions (single or combined size ≥4 cm), Child–Pugh A or selected B, BCLC A–B, adequate non-tumor liver volume and lab values, who are ineligible for or have declined surgery or transplant.

Not a fit: Patients with extrahepatic metastases, macroscopic vascular invasion, arterio-portal or arterio-venous fistulas, prior SIRT, recent sorafenib, prior other malignancies, or who are pregnant or breastfeeding are excluded and unlikely to benefit from this approach.

Why it matters

Potential benefit: If successful, adding SBRT after TACE could improve local tumor control and delay disease progression, potentially extending time before systemic therapy is needed.

How similar studies have performed: Smaller and non-randomized studies have suggested SBRT after TACE can improve local control, but high-quality randomized evidence remains limited.
