Abstract: Introduction: treatment of patients with bilobar metastatic liver disease remains an unsolved problem. Among methods of regional chemotherapy, the least studied is isolated liver chemoperfusion, which is an unpopular technique due to its high trauma and difficult reproducibility. Aim: was to demonstrate the method of endovascular isolated liver chemoperfusion (EILHP) developed by us. Case report: EILCP was performed using a heart-lung machine (HLM) in a patient with cancer of the rectum, stage 2 (pT3N0M0), after combined treatment (radiation therapy (SOD 60 Gy) + anterior resection of the rectum in 2007). Disease progression. Isolated metastatic liver disease (01.2021). Isolated chemoperfusion was performed endovascularly using 2-balloon catheters, which provided vascular isolation of the liver and its isolated perfusion during the procedure. Posi- tioning of balloon catheters was performed in an open way through femoral artery and vein. Perfusion was carried out for 30 minutes with chemotherapy drugs (CtD) oxaliplatin 42,5 mg/m2 and irinotecan 82,5 mg/m2 injected directly into the circuit. Results: the duration of intervention was 160 minutes, intraoperative blood loss was 50 ml. During insertion and positioning of aortic balloon, a limited dissection of the aorta developed in area of left common iliac artery deviation, which did not require any intervention in postoperative period. Duration of intensive care unit stay was 1 day. There were no complications associated with aortic dissection during 3-month follow-up. Level of ALT and AST remained within reference values during entire postoperative period. No hematological toxicity was observed. Patient was discharged on the 7th day after operation in satisfactory condition. Patient underwent control CT scan of abdominal organs, 30 days after endovascular isolated chemoperfusion of the liver. According to the RECIST scale, stabilization of tumor process was noted. Conclusions: proposed technique of endovascular isolated liver chemoperfusion is technically feasible and safe. The use of this method may be appropriate in treatment of patients with isolated liver metastases who require dose reduction of chemotherapeutic agents due to their severe toxicity or high patient comorbidity.
Abstract: Introduction: currently, chemoradiation therapy is widely used as the main method of specific treatment for locally advanced head and neck cancer. Previously it was believed that radiation damage of carotid arteries occurs only several years after treatment. Material and methods: article presents two case reports of internal carotid artery stenosis which arose directly during the course of chemoradiation of head and neck malignant tumors. In the first case, patient K., 54 years old, had laryngeal cancer (stage III: T3N1M0), in the second case, patient M., 40 years old, had tongue cancer (stage I: T1N0M0). Conlusion: article presents angiographically confirmed carotid artery stenosis arisen directly during chemoradiation and in early stages after its completion. The discussion presents data on the incidence of stenosing lesions of carotid arteries, cerebrovascular events among patients undergoing radiation therapy. It is necessary to draw attention of specialists to the problem of early stenosis of carotid arteries during radiation and chemoradiation therapy of head and neck tumors.
