[The value of Roferon-A combined with hepatic artery chemoembolization and portal vein chemotherapy after radical resection in hepatocellular carcinoma for preventing recurrence].

Objective: To explore the change of T cell subsets in patients suffered from hepatocellular carcinoma (HCC) before and after hepatectomy, and study the value of Roferon-A (interferon alpha-2a) combined with hepatic artery chemoembolization (HACE) and portal vein chemotherapy (PVC) after radical resection of HCC for preventing recurrence.

Methods: On 75 HCC patients, PVC and HACE were respectively given at 2 weeks and 4 weeks after radical tumor resection. In 2nd week after surgery, 33 cases of them accepted Roferon-A treatment for 1 week. Seventy-two patients were followed up over 3 years. Effect of Roferon-A combined with HACE and PVC on postoperative recurrence rate was compared with that of HACE and PVC. Changes of T cell subsets in peripheral blood were examined with labeled monoclonal antibodies before and after hepatectomy or using interferon. Forty cholecystolithiasis patients received cholecystectomy were used as the controls.

Results: CD(3)(+) and CD(4)(+) cells in peripheral blood were reduced in patients with HCC. After hepatectomy, they declined further with decrease in CD(4)(+)/CD(8)(+) ratio. The results returned to pre-operative level at the end of 4th week after surgery. The CD(3)(+), CD(4)(+) cells and the CD(4)(+)/CD(8)(+) ratio increased remarkably following the use of Roferon-A. The 1-, 2- and 3-year recurrence rates of patients treated with HACE, PVC and Roferon-A in combination were 0%, 6.2% and 15.6%, respectively, while those treated with HACE and PVC were 5.0%, 12.5% and 27.5%, respectively.

Conclusion: Patients with HCC suffer from marked immuno-suppression which became ever more severe after hepatectomy, combined use of HACE, PVC and Roferon-A is superior to only HACE and PVC by decreasing the recurrence rate.
