Objective: to study influence of regional chemo- and biotherapy on intraoperative blood loss. Materials and methods: An analysis of 122 cases of extensive liver resection accompanied with regional chemotherapy in colorectal metastases patients has been performed. 69 (57%) of them had bilobar lesions, 58 (48%) - had multiple metastases, 27 (22%) - had been resected for extrahepatic metastases. Results: bevacizumab inclusion in preoperative regional chemotherapy did not lead to increase of intraoperative blood loss. Conclusion: Median intraoperative blood loss was 1200 ml in both groups. Up to 6 courses of preoperative antitumor therapy, regardless of route of drug introduction did not increase blood loss. Intraoperative blood loss increases from standard to extended liver resection. Resection of contralateral lobe metastases did not lead to statistically significant increase in blood loss as compared with standard operation.
