ABSTRACT
Introduction. Radiofrequency ablation (RFA) is a recommended curative intent treatment option for patients with early stage hepatocellular
carcinoma (HCC). We investigated if wait times for RFA were associated with residual tumor, tumor recurrence, need for
liver transplantation, or death.
Material and methods. We conducted a retrospective study of patients diagnosed with HCC between
January 2010 and December 2013 presenting to University Health Network (UHN) in Toronto, Canada. All patients receiving
curative intent RFA for HCC were included. Multivariable Cox regression was used to determine if wait times were associated with
clinical outcomes.
Results. 219 patients were included in the study. 72.6% were male and the median age was 62.7 years (IQR
55.6-71). Median tumor size at diagnosis was 21.5 mm (IQR 17-26); median MELD was 8.7 (IQR 7.2-11.4) and 57.1% were Barcelona
stage 0. The cause of liver disease was viral hepatitis in 73.5% (Hepatitis B and C). The median time from HCC diagnosis to
RFA treatment was 96 days (IQR 75-139). In multivariate analysis, wait time was not associated with requiring liver transplant or tumor
recurrence, however, each incremental 30-day wait time was associated with an increased risk of residual tumor (HR = 1.09;
95% CI 1.01-1.19; p = 0.033) as well as death (HR = 1.23; 95% CI 1.11-1.36; p
≤ 0.001).
Conclusion. Incremental 30-day wait
times are associated with a 9% increased risk of residual tumor and a 23% increased risk of death. We have identified system gaps
where quality improvement measures can be implemented to reduce wait times and allocate resources for future RFA treatment,
which may improve both quality and efficiency of HCC care.
