[Two Cases of Transfusion-Free Hepatectomy Following Chemotherapy for H3 Grade of Simultaneous Liver Metastases].

We report 2 cases of transfusion-free treatment for H3 grade of simultaneous liver metastases of the colon which were treated with the chemotherapy followed by R0 liver resection. Case 1 was a 67-year-old woman bearing ascending colon cancer and a metastatic mass occupying the left lobe of the liver with 160 mm in diameter. Laparoscopic ileocecal resection and 30-day left hepatectomy were performed after the 7 courses of FOLFOX plus bevacizumab(BEV). Case 2 was a 72- year-old woman bearing transverse colon cancer with more than 10 foci of liver metastases ranging from 21 mm to 100 mm in diameter. After the transverse colon resection and 12 months of chemotherapy from FOLFOX plus BEV to FOLFIRI plus panitumumab, partial liver resection was performed for each of size-reduced foci. In both patients who declined blood transfusion, optimization of red cells and autologous transfusion with hemodilution contributed to the safe liver resection with no postoperative complications.
