FIELD: medicine, oncology.

SUBSTANCE: the present innovation deals with treating metastatic hepatic disorder in patients with malignant neoplasms. The method of regional polychemotherapy (RPCT) concentrates upon catheterization of proper hepatic artery (PHA) through gastro-omental artery to fulfill intra-arterial RPCT. Moreover, additionally after PHA catheterization it is necessary to catheterize an umbilical vein (UV) due to fulfilling arterio-venous shunting. For this purpose, one should connect catheters introduced into UV and PHA, with the help of a T-joint valve appliance (TVA); before carrying out RPCT it is important to conduct hepatic arterialization due to directing the blood from PHA through UV into the liver by setting TVA valves in position being open for PHA and UV; for carrying out RPCT one should locate TVA valves in position being open for introducing chemopreparations out of the system with a dosing tank of medicinal substances into PHA to carry out the infusion of chemopreparations. Seances for alternating hepatic arterialization and RPCT should be fulfilled daily once a day during the whole course of therapy. The innovation enables to simultaneously increase the concentration of chemopreparations in metastatic hepatic foci, detoxication hepatic function and sensitivity of tumor cells to chemopreparations as a result of additional preliminary oxygenation of hepatocytes.

EFFECT: higher efficiency of therapy.
