Abstract:
Objective To analyze the clinical effects of 131I-HAb18F(ab')2 radioimmunotherapy via hepatic artery on PLC with portal vein tumor emboli. Methods Under the condition of thyroid protection and negative dermal sensitivity test, 12 times of intraarterial injection with 131I labeled murine HCC monoclonal antibody fragment HAb18F(ab')2 were performed in 8 patients of PLC complicated with portal vein tumor emboli. A 0.75 mCi/kg dose of 131I was administrated individually into certain target vessel after hepatic artery angiography using Seldinger technique. Results 3 of 7 patients with symptoms of pains showed remission with simultaneous improvement and stabilization in Karnofsky score in 3 and 4 patients respectively. AFP levels decreased about 50%(3/6)in 3 cases among those 6 positives and the values of I.B. and ALT changed within a very narrow range to a certain extent after the treatment. The overall rate of CR + PR was 28.6% and similar better result was obtained in a non-symptomatic diffuse PLC patient.1 year survival rate was 12.5%. Conclusion 131I-HAb18F(ab')2 radioimmunotreating drug(0.75 mCi/kg)with hypotoxicity to liver-function can be used as an acceptable method for unresectable PLC with portal vein tumor emboli, especially for those without tumor emboli in the main trunk.
