The tumor tissues were sent for patho-histology and electron microscopic examinations. The diameters of tumors were measured with high frequency ultrasound before and after therapies and tumor growth index (TGI) was calculated. (2) Clinical study: Tumors of 122 cases of pathologically proved HCC were injected with quantified ethanol guided by ultrasound every 3-5 d 4-10 times per period of treatment. The quantity of ethanol was calculated according to the regressive equations where Y = 2.885X when the mass was ≤5 cm in diameter and Y = 1.805X when the mass was >5 cm in diameter (X is the maximal diameter of the mass with the unit cm, Y is the ethanol quantity with the unit mL). The survival rates of 1, 2, 3 and 4 years and recurrent rates in situas well as dystopia in the liver were calculated.RESULTS: (1) Experimental study: TGI of QESI group (0.072:1:0.018) and QELI group (0.094:1:0.028) was apparently lower than that of SQLI group (1.982:1:0.482) (P<0.01). TGI of QESI group seemed to be lower than that of QELI group, but it was not markedly different (P>0.05) between two groups. Severe degeneration and necrosis could be seen in QESI group by patho-histology examination. Coagulative necrosis could be seen in most tumors of QESI group and there were no residual cancer cells under electronic microscope, while the residual cancer and inflammatory cells and fibre tissues cou展开更多

Of the" 240 patients, 163 had recurrent liver cancer, 55 had inoperable liver cancer because of cardiac, pulmonary, hepatic and renal dysfunctions or due to the close proximity of tumor to the major vessels, and 22 refused to receive surgical resection. In 40 patients who received surgical resection after PEIT treatment, the resected tumors were pathologically evaluated for necrotic status and the patients were followed up postoperatively.Results Postoperative 1-, 2- and 3-year survival rate of the 240 patients was 94.9% , 84.2% and 66.3% respectively. Conclusion PEIT can be used as a non-invasive treatment for SPLC, and preoperative PEIT appears to be helpful in reducing recurrence of postoperative liver cancer.展开更多
