The retrospective study enrolled all metastatic colorectal cancer patients who had undergone liver resection or radiofrequency ablation (RFA) at the Department for Surgery of the Liver, Biliary Tract, and Pancreas, Acad. B.V. Petrovsky Russian Research Center of Surgery, in the period of May 2006 to May 2011, and who had perioperatively used bevacizumab in combination with cytotoxic chemotherapy. The study encompassed 21 patients who had preoperatively received bevacizumab in combination with cytotoxic agents and undergone liver resection or RFA for colorectal cancer metastases.
A total of 21 patients underwent 17 hepatic resections, including 5 right-sided resections, 4 left-sided resections, 7 atypical resections, 1 extended right-sided resection, and 6 RFAs for metastases. Median blood loss was 300 ml. The mean duration of surgery was 240 min. The majority (66%) of the patients needed no intraoperative blood transfusion. There were no fatal cases in the perioperative period. The rate of postoperative complications was 23,8%. The mean follow-up period in this group of patients was 18 months. The three-year survival rate estimated by the Kaplan–Meier method was 67% after surgery and 82% after primary tumor surgery. According to the results of our study, addition of bevacizumab to preoperative cytotoxic chemotherapy is not followed by the higher rate of perioperative complications. Furthermore, high 3-year survival rates can be achieved after preoperative drug therapy and liver surgery for colorectal cancer metastases.
Key words: metastatic colorectal cancer, liver resection, bevacizumab, preoperative chemotherapy.
