Objective: The objective of our study was to describe survival outcome in 124 patients with unresectable hepatocellular carcinoma treated with triple-drug transcatheter arterial chemoembolization (TACE) using doxorubicin, cisplatin, and mitomycin C using a standardized regimen.
Materials and methods: One hundred twenty-four patients underwent TACE using a standardized triple-drug regimen. Embolization was performed using subselective coaxial embolization technique. Fifty-six patients (group 1) received triple-drug TACE in conjunction with a nonpermanent embolic agent, microfibrillar collagen (Avitene), and 68 patients (group 2) had triple-drug TACE with a permanent embolic agent, Embosphere Microspheres.
Results: Twenty-eight patients underwent liver transplantation after TACE, and survival in these patients was significantly longer than those who did not receive a transplant (p < or = 0.001). The mean survival for the no-transplant group (n = 96) was longer in patients with Child-Pugh class A cirrhosis than in those with Child-Pugh class B cirrhosis (30.3 +/- 2.92 [standard error] vs 11.6 +/- 2.84 months, respectively; p < 0.001), in those with Okuda stage I versus stage II disease (31.4 +/- 3.03 vs 17.4 +/- 3.16 months; p = 0.002), and in those with a pre-TACE bilirubin level of less than 2.5 mg/dL (42.75 micromol/L; 28.3 +/- 2.75 vs 13.2 +/- 3.83 months; p = 0.007). Improved survival was seen in the no-transplant patients receiving TACE with the permanent embolic agent (group 2) than in those receiving TACE with the nonpermanent agent (group 1) out to 30 months (p = 0.002). Complications occurred in 16 patients (12.9%). The 30-day mortality was 2.4%.
Conclusion: Patients with hepatocellular carcinoma who underwent triple-drug TACE followed by liver transplantation showed the longest survival. Patients who did not receive a transplant and were treated with triple-drug TACE with a permanent embolic agent showed longer survival to 30 months after TACE than those receiving a nonpermanent embolic agent.
