Introduction: Small studies from outside of the USA suggest excellent outcomes after surgical resection for hepatocellular carcinoma (HCC) with vascular invasion. The study aims to (1) compare overall survival after surgical resection and systemic therapy among patients with HCC and vascular invasion and (2) determine factors associated with receipt of surgical resection in a US population. Methods: HCC patients with AJCC clinical TNM stage 7th T3BN0M0 diagnosed between 2010 and 2017 from the National Cancer Database were analyzed. Cox and logistic regression analyses identified factors associated with overall survival and receipt of surgical resection. Results: Of 11,259 patients with T3BN0M0 HCC, 325 (2.9%) and 4,268 (37.9%) received surgical resection and systemic therapy, respectively. In multivariable analysis, surgical resection was associated with improved survival compared to systemic therapy (adjusted hazard ratio: 0.496, 95% confidence interval: 0.426–0.578) with a median survival of 21.4 and 8.1 months, respectively. Superiority of surgical resection was observed in noncirrhotic and cirrhotic subgroups and propensity score matching and inverse probability of treatment weighting adjusted analysis. Asians were more likely to receive surgical resection, whereas Charlson comorbidity ≥3, elevated alpha-fetoprotein, smaller tumor size, care in a community cancer program, and the South or West region were associated with a lower likelihood of surgical resection. Conclusion: HCC patients with vascular invasion may benefit from surgical resection compared to systemic therapies. Demographic and clinical features of HCC patients and region and type of treating facility were associated with surgical resection versus systemic treatment.

Objective: Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related mortality worldwide, and a rising cause of cancer mortality in the U.S. Liver cirrhosis is the major risk factor for HCC. Surveillance of persons with cirrhosis facilitates early detection and improves outcomes. We assessed the surveillance rate for HCC within a major academic health system and identified factors influencing surveillance. Patients and Methods: We examined the surveillance rate for HCC using liver ultrasound, CT, or MRI, and factors influencing surveillance in a cohort of 369 Minnesota residents with cirrhosis seen at the Mayo Clinic between 2007 and 2009. Results: Ninety-three percent of cirrhosis patients received at least one surveillance study, but only 14% received the recommended uninterrupted semiannual surveillance. Thirty percent received ≥75% of recommended surveillance, and 59% received ≥50% of recommended surveillance. Factors increasing surveillance included gastroenterology or hepatology specialist visits (p < 0.0001), advanced liver disease as assessed by hepatic encephalopathy (p = 0.0008), and comorbid illness as assessed by diabetes mellitus (p = 0.02). Age, sex, race, residence, cirrhosis etiology, or number of primary care visits did not significantly affect the rate of surveillance. Conclusions: While the rate of surveillance in a major academic health system was higher than reported in other studies, surveillance was heavily dependent on visits to a subspecialist. This suggests a major and urgent national need to improve identification of individuals at risk for HCC in the primary care setting and the initiation and maintenance of surveillance by primary care practitioners.
