Popis: Objective:To investigate the functional liver regeneration after chemotherapy and liver resection for colorectal liver metastases (CRLM).Background/Purpose:Preoperative chemotherapy followed by liver resection for CRLM has been increasing; however, its negative impact on liver regeneration remains unknown.Methods:From January 2009 to December 2013, we enrolled 40 selected patients who underwent major hepatectomy without viral hepatitis and severe liver fibrosis. CRLM patients with preoperative chemotherapy (CT-CRLM group, n = 12) and patients without preoperative chemotherapy (control group, n = 28) were evaluated. Liver volume (LV) and functional liver volume (FLV) was assessed using Tc-99m–labeled galactosyl human serum albumin (99mTc-GSA) scintigraphy, single-photon emission computed tomography (SPECT), CT-fused images. Preoperative, future remnant liver, and post 1-month values were compared.Results:Median course of preoperative chemotherapy was 8 (range: 6–16). Preoperative background factors were almost identical including resection rate and functional resection rate. In the CT-CRLM group and in the control group, the percentage increases in LV were 39.3% ± 29.0% and 23.2% ± 23.5% (P = 0.037), and FLV were 79.4% ± 43.1% and 57.0% ± 33.4% (P = 0.417), respectively; absolute differences in LV were 216.2 ± 155.7 cm3 and 148.7 ± 134.7 cm3 (P = 0.086) and FLV were 19.4% ± 8.5%/m2 and 17.4% ± 7.9%/m2 (P = 0.235), respectively. We found no obvious tendency for negative influence on liver functional regeneration by the preoperative regimens for CRLM.Conclusions:Several courses of preoperative chemotherapy may not affect functional liver regeneration for CRLM patients after major hepatectomy.
