Radiotherapy versus observation for liver metastases in small cell lung cancer

Official title: A Prospective Phase II Randomized Clinical Study of Radiotherapy or Observation of Liver Metastases for Small Cell Lung Cancer.

Run by Guizhou Medical University · NCT05150145 · Data updated 2026-11-12

This trial tests whether giving radiotherapy to the liver after chemotherapy helps people with small cell lung cancer that has spread to the liver live longer and control tumors better than observation.

Is this trial a fit for you?

Likely a good fit

Adults 18–70 with confirmed small cell lung cancer and liver metastases, ECOG performance status 0–2, adequate organ function, and no prior thoracic radiotherapy or surgery are ideal candidates.

Probably not a fit

Patients with poor performance status, other active malignancies, significant organ dysfunction, a history of mental illness precluding consent, or who cannot tolerate radiotherapy are unlikely to benefit.

What this trial studies

This is a prospective, randomized study comparing liver (and thoracic) radiotherapy to observation in patients with small cell lung cancer who have liver metastases after systemic chemotherapy. Eligible participants are adults 18–70 with histologically or cytologically confirmed SCLC, ECOG 0–2, adequate blood, liver and kidney function, and no prior thoracic radiotherapy or surgery. The main outcomes are local tumor control, survival outcomes, and treatment-related complications, with safety and tolerability monitored during follow-up. The single-center trial is led by Guizhou Medical University and aims to fill a gap in evidence on whole-liver radiotherapy in SCLC.

Why it matters

Potential benefit: If successful, adding liver radiotherapy could improve local tumor control and potentially extend survival for patients with SCLC and liver metastases.

How similar studies have gone: Local radiotherapy has benefited liver metastases in other cancers, but whole-liver radiotherapy specifically for small cell lung cancer remains largely untested.
