To study the clinical value of intrahepatic injections of Highly Agglutinative Staphylococcin (HAS) in the interventional treatment of liver carcinomas. Under ultrasonic guidance, intrahepatic injections of HAS were administered in 22 cases of pathologically diagnosed liver carcinomas, 3 days, 7 days, 30 days, 3 months, 6 months, 9 months, and 12 months after microwave coagulation therapy. The dose of each injection was 2000U. Immunohistochemical staining of the sample from the tumor site after HAS administrations demonstrated a significant increase in the number of antitumor immune cells compared with that before the injections (p<0.01) and an improvement in local immune status. One-year survival rate and recurrence rate, which were determined by Kaplan- Meier method, were 93.8% and 81.9% respectively. As a new route of administration, intrahepatic injections of HAS are a safe and effective procedure and deserves further clinical research and discussion.
