[Clinical study of the surgical treatment of hepatocarcinoma with an implantable microwave device].
This article reports the surgical treatment to 51 patients with mid and advanced hepatocarcinoma by the self-made implantable microwave radiation apparatus from April, 1987 to April 1989. By way of histology, histochemistry, and electronic microscopy, we studied the killing effect on cancer cells, the range of the effect and the remarkable hemostatic mechanism of this implantable microwave device. Clinically, we developed six different methods of operate with the microwave. Without the need of blocking hepatic portal, this new approach simplifies the operation. The risk of iatrogenic cancerous diffusion and hemorrhage is also greatly reduced or prevented in hemihepatectomy. Initial results shows that the resection rate of the hepatocarcinoma went up from 20-42.5 percent to 74.5 percent. Microwave operation on 38 patients with advanced hepatocarcinoma reveals a survival rate of 75 percent over 6 months. The authors believe that this new operative method is effective in the treatment to advanced hepatic carcinoma, and prolongs the life of the patients.
