摘 要 目的：探讨超声介入注射无水酒精治疗肝癌的量化方法。方法：对86例162个复发性肝癌结节在超声引导下行无水酒精注射治疗(PEI),计算①酒精注射量与弥散范围最大径的相关系数;②肿块大小与酒精注射量的回归方程。结果：酒精注射量与弥散范围呈非常显著正相关(r=0.884,P=0.000), 肿瘤结节大小与酒精注射量的回归方程为:当肿瘤直径≤5cm时为Y=2.885X,当肿瘤直径>5cm时, 其回归方程为Y=1.805X(式中X为肿瘤最大径cm, Y为酒精注射量ml)。结论：通过酒精注射量与弥散范围的相关关系研究导出的肿瘤结节直径与酒精注射量的回归方程经临床应用与随访观察,具有肯定的疗效, 可作为行PEI时酒精注射量的计算方法。

ABSTRACT Objective:To probe the methodof percutaneous ethanol injection(PEI) in treatment of hepatocarcinoma. Methods：Onehundred sixty two recurrent hepatocarcinoma in 86 patients were treated by ultrasoundguided PEI. The interrelated coefficient of the quantity of alcohol injected into themasses and the diameters of spreading areaes of the alcohol on the screen were measured.Also the regressie equation of the diameters of the mass and the quantity of alcohol wascalculated. Results:The quantity of alcohol and the alcohol spreading area is markedlypositive interrelated (r=0.884, P=0.000). The regressive equation of the diameter of themass and the quantity of alcohol is Y=2.885X when the diameter of the mass is≤5cm, andY=1.805X when the mass is>5cm (X is the mass diameter, Y is the alcohol quantity. Theunit is ml). Conclusion:Hepatocarcinoma is cured by PEI with the quantified alcoholcalculated by the regressive equation of the diameter of the mass and the quantifiedalcohol inferred from the interrelationship between the quantity of alcohol and thediameter of spreading area of the alcohol.
