Key clinical point: Abdominal ultrasonography (US) blind spots affect the initially detected hepatocellular carcinoma (HCC) tumor size, treatment strategy, and overall survival (OS) in patients with HCC who undergo regular surveillance.
Major finding: A significantly higher proportion of HCC tumors >2 cm were detected in blind vs non-blind spots (60.3% vs 47.1%; P = .001), with most being treated with hepatectomy (P < .001) vs radiofrequency ablation, respectively. Patients with HCC located in a blind spot in the US-detected vs US-missed group had a significantly better OS (P = .008).
Study details: This retrospective study included 1289 patients who underwent 6-month interval surveillance using US and serum alpha-fetoprotein and were eventually diagnosed with single-nodular Barcelona Clinic Liver Cancer stage 0-A HCC that was detected (n = 1062) or missed (n = 227) by US.
Disclosures: This study was supported by a grant from the Medical Science Research Institute, Kyung Hee University Hospital at Gangdong, South Korea. The authors declared no conflicts of interest.
