摘要

•HCC surveillance was associated with improved early-stage detection, curative treatment receipt, and prolonged survival.•Semi-annual surveillance intervals were associated with improved early HCC detection and overall survival.•Few studies evaluated surveillance outcomes in post-SVR or NAFLD patient populations; thus, future research is warranted.•Few studies characterized surveillance-related harms, although available data suggest surveillance harms are mild in severity. Background & AimsThere is controversy regarding the overall value of hepatocellular carcinoma (HCC) surveillance in patients with cirrhosis given the lack of data from randomized-controlled trials. To address this issue, we conducted a systematic review and meta-analysis of cohort studies evaluating the benefits and harms of HCC surveillance in patients with cirrhosis.MethodsWe performed a search of the Medline and EMBASE databases and national meeting abstracts from January 2014 through July 2020 for studies reporting early-stage HCC detection, curative treatment receipt, or overall survival, stratified by HCC surveillance status, among patients with cirrhosis. Pooled risk ratios (RRs) and hazard ratios, according to HCC surveillance status, were calculated for each outcome using the DerSimonian and Laird method for random effects models.ResultsWe identified 59 studies including 145,396 patients with HCC, which was detected by surveillance in 41,052 (28.2%) cases. HCC surveillance was associated with improved early-stage detection (RR 1.86, 95% CI 1.73–1.98; I2 = 82%), curative treatment receipt (RR 1.83, 95% CI 1.69–1.97; I2 = 75%), and overall survival (hazard ratio 0.67, 95% CI 0.61–0.72; I2 = 78%) after adjusting for lead-time bias; however, there was notable heterogeneity in all pooled estimates. Four studies examined surveillance-related physical harms due to false positive or indeterminate surveillance results, but no studies examined potential financial or psychological harms. The proportion of patients experiencing surveillance-related physical harms ranged from 8.8% to 27.5% across studies, although most harms were mild in severity.ConclusionHCC surveillance is associated with improved early detection, curative treatment receipt, and survival in patients with cirrhosis, although there was heterogeneity in pooled estimates. Available data suggest HCC surveillance is of high value in patients with cirrhosis, although continued rigorous studies evaluating benefits and harms are still needed.Lay summaryThere has been ongoing debate about the overall value of hepatocellular carcinoma (HCC) screening in patients with cirrhosis given the lack of data from randomized-controlled trials. In a systematic review of contemporary cohort studies, we found that HCC screening is associated with improved early detection, curative treatment receipt, and survival in patients with cirrhosis, although there were fewer data quantifying potential screening-related harms. Available data suggest HCC screening is of high value in patients with cirrhosis, although continued studies evaluating benefits and harms are still needed.
