Using PDOX to guide chemotherapy after liver cancer surgery

Applicability of Patient Derived Orthotopic Xenograft (PDOX) in Patients With Primary Liver Cancer: A Randomized Controlled Trial

Phase 3 Interventional Zhujiang Hospital · NCT05766605

This study is testing if using a special lab-grown model of liver cancer can help doctors choose the best chemotherapy for patients after they have surgery for liver cancer.

What this trial studies

This randomized controlled trial evaluates the clinical feasibility of PDOX (Patient-Derived Orthotopic Xenograft) results in determining the use of interventional chemotherapy following radical surgery for primary liver cancer. Patients who have undergone radical surgical resection for hepatocellular carcinoma will be enrolled and treated with various chemotherapy agents, including Oxaliplatin and Doxorubicin. The primary endpoint is the one-year disease-free survival rate, while secondary endpoints include the assessment of adverse events. Data will be collected from patients receiving PDOX to inform treatment decisions post-surgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 who have undergone radical surgical resection for hepatocellular carcinoma and meet specific health criteria.

Not a fit: Patients with recurrent liver cancer or those with existing distant metastases will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve disease-free survival rates for patients with hepatocellular carcinoma after surgery.

How similar studies have performed: While the use of PDOX in guiding chemotherapy is a novel approach, similar studies have shown promise in other cancer types, suggesting potential for success.
