ABSTRACT

BACKGROUND: The aim of this study was to perform a systematic review and meta-analysis to investigate the impact of lymph node dissection (LND) on outcomes following resection of intrahepatic cholangiocarcinoma (ICC). METHODS: PubMed, EMBASE, and Cochrane were searched from inception to 30th January 2023 for studies that compared LND with no LND (NLND) among patients with ICC. To limit the effect of unbalanced covariates, only studies that utilized propensity score-based methods were included. Subgroup analysis of patients with clinically node-negative (cN0) ICC was analyzed. RESULTS: Among 3776 patients with ICC, individuals in the LND versus NLND cohorts had comparable overall survival (OS) (Hazard ratio [HR] 0.78, 95 % confidence interval [CI] 0.57-1.06, P = 0.11), disease-free survival (DFS) (HR 0.84, 95 % CI 0.70-1.01, P = 0.07) and risk of major complications (odds ratio [OR] 1.07, 95 % CI 0.70-1.62, P = 0.75). Subgroup analysis of cN0 patients, OS was significantly higher in patients who underwent LND (HR 0.61, 95 % CI 0.50-0.74, P < 0.01), with a non-significant trend towards improved DFS (HR 0.81, 95 % CI 0.65-1.01, P = 0.06). CONCLUSION: This study found no differences in long-term survival or morbidity following LND for ICC. Subgroup analysis of cN0 patients, who underwent LND detected improved OS with a trend towards better DFS, compared to patients with NLND.

ABSTRACT

BACKGROUND: The exact role of laparoscopic liver resection (LLR) in patients with hepatocellular carcinoma (HCC) and underlying liver cirrhosis (LC) is not well defined. In this meta-analysis, both long- and short-term outcomes following LLR versus open liver resection (OLR) were analysed. METHODS: PubMed, EMBASE, Scopus and Web of Science databases were searched systematically for randomised controlled trials (RCTs) and propensity-score matched (PSM) studies reporting outcomes of LLR versus OLR of HCC in patients with cirrhosis. Primary outcome was overall survival (OS). This was analysed using one-stage (individual participant data meta-analysis) and two-stage (aggregate data meta-analysis) approaches. Secondary outcomes were operation duration, blood loss, blood transfusion, Pringle manoeuvre utilization, overall and major complications, length of hospital stay (LOHS), 90-day mortality and R0 resection rates. RESULTS: Eleven studies comprising 1618 patients (690 LLR versus 928 OLR) were included for analysis. In the one-stage meta-analysis, an approximately 18.7 per cent lower hazard rate (HR) of death in the LLR group (random effects: HR 0.81, 95 per cent confidence interval [C.I.] 0.68 to 0.96; P = 0.018) was observed. Two-stage meta-analysis resulted in a pooled HR of 0.84 (95 per cent C.I. 0.74 to 0.96; P = 0.01) in the overall LLR cohort. This indicated a 16-26 per cent reduction in the HR of death for patients with HCC and cirrhosis who underwent LLR. For secondary outcomes, LLR was associated with less blood loss (mean difference [MD] -99 ml, 95 per cent C.I. -182 to -16 ml), reduced overall complications (odds ratio 0.49, 95 per cent C.I. 0.37 to 0.66) and major complications (odds ratio 0.45, 95 per cent C.I. 0.26 to 0.79), and shorter LOHS (MD -3.22 days, 95 per cent C.I. -4.38 to -2.06 days). CONCLUSION: Laparoscopic resection of HCC in patients with cirrhosis is associated with improved survival and perioperative outcomes.
