Objective: To examine the feasibility, clinical efficacy and complications of percutaneous trans-arterial implantation of port-catheter system (PCS) for intervention treatment of advanced malignant tumors.
Methods: Fifty-three cases with advanced malignant tumors were treated by infusion of chemotherapeutic drugs and/or chemo-embolization through PCS. Patients received one course of treatment every 4-6 weeks.
Results: In this series of treated patients, the survival period was 5-18 months with a mean survival time of 13.5 months. The overall response rate (CR + PR) was 62.3%. Detachment of the catheter tip occurred in 2 cases. Disruption of wound after removal of stitches occurred in one case and skin necrosis at the port occurred in another.
Conclusion: Long-term intervention treatment with PCS is simple and safe. It is a treatment of choice for patients with advanced malignancy.
