Comparing surgery and palliative care for liver metastases in pancreatic cancer

Official title: Conversion Surgery Vs. Palliative Care in Pancreatic Cancer Oligometastatic to the Liver (SONAR: Surgery in Oligometastatic PaNcreatic CAnceR) a Randomized Controlled Trial

Run by Azienda Ospedaliera di Padova · NCT06690528 · Data updated 2026-11-12

This study is testing if surgery to remove both the main pancreatic tumor and liver metastases can help people with pancreatic cancer live longer and feel better compared to just receiving palliative care.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-75 with oligometastatic pancreatic adenocarcinoma limited to the liver and stable disease or response after first-line chemotherapy.

Probably not a fit

Patients with extrahepatic metastases or those not responding to initial chemotherapy may not benefit from this study.

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

What this trial studies

This study investigates whether surgical resection of the primary tumor and liver metastases can improve survival and quality of life compared to palliative care in patients with oligometastatic pancreatic cancer. It focuses on patients who have stable disease or a response to chemotherapy and are eligible for surgery. The trial is an international, multicenter randomized study that will recruit 56 patients, assigning them to either the surgical group or the palliative care group. Outcome assessments will include clinical evaluations, imaging, and quality-of-life metrics over a minimum two-year follow-up period.

Why it matters

Potential benefit: If successful, this approach could lead to improved survival rates and quality of life for patients with oligometastatic pancreatic cancer.

How similar studies have gone: Other studies have explored surgical interventions for oligometastatic pancreatic cancer, but this specific approach is still under investigation.

* Decreasing or stable (defined as ≤20% increase) serum CA19-9 level after chemotherapy (at enrollment).
* Liver metastases considered resectable (see section 5) or alternatively treatable by needle ablation/microwave once no larger than 20 mm (at enrollment).

Exclusion Criteria:
