- <b><i>Background:</i></b><i></i> There is limited knowledge about the mechanisms behind the unparalleled growth of the future liver remnant (FLR) linked to associating liver partition and portal vein ligation for staged hepatectomy (ALPPS). In this study, liver regenerative markers were examined in patients subjected to ALPPS. <b><i>Methods:</i></b><i></i> Ten patients with colorectal liver metastases treated with neoadjuvant chemotherapy and ALPPS were included. Plasma was sampled at 6 time points and biopsies from both liver lobes were collected at both stages of ALPPS. The levels of interleukin (IL)-6, hepatocyte growth factor (HGF), tumor necrosis factor-α, epidermal growth factor, and vascular endothelial growth factor in plasma were measured at each time point. Expression of mRNA for markers of proliferation and apoptosis was studied in the biopsies from both liver lobes taken at both stages. <b><i>Results:</i></b><i></i> ALPPS resulted in a peak of IL-6 after stage 1 (<i>p</i> = 0.004), which decreased rapidly and did not increase again after stage 2. HGF also increased after stage 1 (<i>p</i> = 0.048), and the HGF levels correlated significantly with the degree of growth of the FLR before stage 2 (<i>p</i> = 0.02, <i>r</i><sup>2</sup> = 0.47). There was a correlation between peak levels of IL-6 and HGF (<i>p</i> = 0.03, <i>r</i><sup>2</sup> = 0.84). <b><i>Conclusions:</i></b><i></i> IL-6 and HGF seem to be early mediators of hypertrophy after stage 1 in the ALPPS procedure. The peak HGF plasma level correlates with the degree of FLR growth in patients subjected to ALPPS.
