Repeated use of hybrid isolated chemoperfusion with melphalan in non-resectable liver malignancy

Background. The incidence of liver malignancies is increasing, radical surgery can be performed in a small number of patients, most of them receive drug treatment. Isolated liver chemoperfusion (ILP) is a method of regional chemotherapy that is effective for some metastases but has a high complexity and frequency of complications. An improved method of hybrid ILP may offer new opportunities for patients with unresectable liver tumors. Case report. A 64-year-old patient diagnosed with stage IV sigmoid colon cancer underwent hybrid ILP. The patient was discharged after 6 days in a satisfactory condition without complications. Systemic chemotherapy was performed 21 days after the first hybrid chemoperfusion. The second hybrid chemoperfusion procedure was performed without the laparotomy stage, mobilizing the right common femoral vein and artery. As a result of the chemotherapy, the patients received a positive result on the mRECIST scale – a complete tumor response. Conclusion. The developed method of hybrid ILP has several advantages over traditional ILP and chemosaturation with infusion into the hepatic artery. This method can also be performed repeatedly, which is not possible with traditional ILP.
