BACKGROUND/AIMS: The purpose of this study was to evaluate the safety and efficacy of predeposit autologous blood transfusion for resection of hepatic metastases. METHODOLOGY: We examined stored blood from 25 patients with advanced colorectal or gastric cancer for carcinoembryonic antigen mRNA using reverse-transcriptase-polymerase chain reaction assay to detect cancer cell in the autologous blood. We also retrospectively evaluated no transfusion (A, n = 44), autologous transfusion (B, n = 15), and homologous transfusion groups (C, n = 26) for perioperative liver function and long-term outcome after undergoing resection of liver metastases. RESULTS: In 5 of 25 patients, carcinoembryonic antigen mRNA was detected immediately after blood donation and after 7 days of storage, but not after 14-21 days of storage. The cumulative 5-year survival rates for groups A, B, and C were not different. However, disease-free survival with colorectal liver metastases was significantly higher in group A than in group C (P = 0.019). Total bilirubin concentrations in group C on the first postoperative day were also significantly higher than group A (P = 0.025). CONCLUSIONS: Stored autologous blood may contain cancer cells, but these decrease or disappear after storage for more than 7 days. For hepatic resection of metastases, transfusion avoidance yields the optimal outcome.
