[Effect of radiologic contrast chemoembolization on ultrastructural changes of malignant liver neoplasms]

The authors confirm the efficacy of treating primary and metastatic cancer of the liver by selective blocking of vessels in the involved liver part with an oily x-ray contrast agent with a citostatic dioxadet. Profound irreversible injury to tumor tissue was observed. Only solitary tumor cells were left slightly injured. Excepting a narrow adjacent area, lesser amount of lipid tissue accumulated in the tumor; hepatocytes were sufficiently well preserved, showing signs of reparation and increased functional activity 1-2 weeks after chemoembolization.
