Abstract

Immune dysregulation may be associated with cancer progression. We sought to investigate the prognostic value of perioperative lymphopenia on short- and long-term outcomes among patients undergoing resection of hepatocellular carcinoma (HCC).Patients undergoing resection of HCC between 2000 and 2020 were identified using an international database. The incidence and impact of perioperative lymphopenia [preoperative, postoperative day (POD) 1/3/5], defined as absolute lymphocyte count (ALC) <1000/µL, on short- and long-term outcomes was assessed.Among 1448 patients, median preoperative ALC was 1593/µL [interquartile range (IQR) 1208-2006]. The incidence of preoperative lymphopenia was 14.0%, and 50.2%, 45.1% and 35.6% on POD1, POD3 and POD5, respectively. Preoperative lymphopenia predicted 5-year overall survival (OS) [lymphopenia vs. no lymphopenia: 49.1% vs. 66.1%] and 5-year disease-free survival (DFS) [25.0% vs. 41.5%] (both p < 0.05). Lymphopenia on POD1 (5-year OS: 57.1% vs. 71.2%; 5-year DFS: 30.0% vs. 41.1%), POD3 (5-year OS: 57.3% vs. 68.9%; 5-year DFS: 35.4% vs. 42.7%), and POD5 (5-year OS: 53.1% vs. 66.1%; 5-year DFS: 32.8% vs. 42.3%) was associated with worse long-term outcomes (all p < 0.05). Patients with severe lymphopenia (ALC <500/µL) on POD5 had worse 5-year OS and DFS (5-year OS: 44.7% vs. 54.3% vs. 66.1%; 5-year DFS: 27.8% vs. 33.3% vs. 42.3%) [both p < 0.05], as well as higher incidence of overall (45.5% vs. 25.3% vs. 30.9%; p = 0.013) and major complications (18.2% vs. 3.4% vs. 4.5%; p < 0.001) versus individuals with moderate (ALC 500-1000/µL) or no lymphopenia following hepatectomy for HCC. After adjusting for competing risk factors, prolonged lymphopenia was independently associated with higher hazards of death [hazard ratio (HR) 1.38, 95% CI 1.11-1.72] and recurrence (HR 1.22, 95% CI 1.02-1.45).Perioperative lymphopenia had short- and long-term prognostic implications among individuals undergoing hepatectomy for HCC.
