Sumario:BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is an innovative surgical approach for the treatment of massive hepatocellular carcinoma (HCC), the key to successful planned stage 2 ALPPS is future liver remnant (FLR) volume growth, but the exact mechanism has not been elucidated. The correlation between regulatory T cells (Tregs) and postoperative FLR regeneration has not been reported. AIM: To investigate the effect of CD4(+)CD25(+) Tregs on FLR regeneration after ALPPS. METHODS: Clinical data and specimens were collected from 37 patients who developed massive HCC treated with ALPPS. Flow cytometry was performed to detect changes in the proportion of CD4(+)CD25(+) Tregs to CD4(+) T cells in peripheral blood before and after ALPPS. To analyze the relationship between peripheral blood CD4(+)CD25(+) Treg proportion and clinicopathological information and liver volume. RESULTS: The postoperative CD4(+)CD25(+) Treg proportion in stage 1 ALPPS was negatively correlated with the amount of proliferation volume, proliferation rate, and kinetic growth rate (KGR) of the FLR after stage 1 ALPPS. Patients with low Treg proportion had significantly higher KGR than those with high Treg proportion (P = 0.006); patients with high Treg proportion had more severe postoperative pathological liver fibrosis than those with low Treg proportion (P = 0.043). The area under the receiver operating characteristic curve between the percentage of Tregs and proliferation volume, proliferation rate, and KGR were all greater than 0.70. CONCLUSION: CD4(+)CD25(+) Tregs in the peripheral blood of patients with massive HCC at stage 1 ALPPS were negatively correlated with indicators of FLR regeneration after stage 1 ALPPS and may influence the degree of fibrosis in patients’ livers. Treg percentage was highly accurate in predicting the FLR regeneration after stage 1 ALPPS.
