Effects ofαInterferon on Long-term Survival Rate and Tumor Recurrence After Radical Hepatic Resection / 中国药房

ABSTRACT

OBJECTIVE:To investigate the effect of α-interferon on long-term survival rate and tumor recurrence after radical hepatic resection. METHODS:104 patients with primary hepatocellular carcinoma underwent radical hepatic resection were divided into observation group(62 cases)and control group(42 cases). Observation group was treated with IFN-α for 18 months 4-6 weeks after surgery;control group received rountine treatment. Total survival rate and disease-free survival rate after surgery were com-pared between 2 groups. RESULTS:In observation group after surgery,1-year survival rate was 82.26%(51/62),3-year survival rate 61.29%(38/62),and 5-year survival rate 24.19%(15/62);in control group after surgery,1-year survival rate was 41.94%(26/62),3-year survival rate 28.57%(12/42)and 5-year survival rate 9.52%(4/42);there was statistically significant difference in postoperative survival rate between 2 groups (P<0.05). In observation group after surgery,1-year disease-free survival rate was 61.29%(38/62),3-year disease-free survival rate 40.32%(25/62),and 5-year disease-free surial rate 17.74%(11/62);in control group after surgery,1 year disease-free survival rate was 43.55%(27/62),3 year disease-free survival rate 22.58%(14/62),and 5-year disease-free surial rate was 0(0/62);there was statistically significant difference in postoperative disease-free survival rate be-tween 2 groups (P<0.05). CONCLUSIONS:The application of α-interferon after radical hepatic resection can significantly inhibit the recurrence of postoperative tumor,improve the long-term survival rate,and is worthy of clinical research.
