Background:
Patients with cirrhosis and subcentimeter lesions on liver ultrasound are recommended to undergo short-interval follow-up ultrasound because of the presumed low risk of primary liver cancer (PLC).
Aims:
The aim of this study is to characterize recall patterns and risk of PLC in patients with subcentimeter liver lesions on ultrasound.
Methods:
We conducted a multicenter retrospective cohort study among patients with cirrhosis or chronic hepatitis B infection who had subcentimeter ultrasound lesions between January 2017 and December 2019. We excluded patients with a history of PLC or concomitant lesions ≥1 cm in diameter. We used Kaplan Meier and multivariable Cox regression analyses to characterize time-to-PLC and factors associated with PLC, respectively.
Results:
Of 746 eligible patients, most (66.0%) had a single observation, and the median diameter was 0.7 cm (interquartile range: 0.5–0.8 cm). Recall strategies varied, with only 27.8% of patients undergoing guideline-concordant ultrasound within 3–6 months. Over a median follow-up of 26 months, 42 patients developed PLC (39 HCC and 3 cholangiocarcinoma), yielding an incidence of 25.7 cases (95% CI, 6.2–47.0) per 1000 person-years, with 3.9% and 6.7% developing PLC at 2 and 3 years, respectively. Factors associated with time-to-PLC were baseline alpha-fetoprotein >10 ng/mL (HR: 4.01, 95% CI, 1.85–8.71), platelet count ≤150 (HR: 4.90, 95% CI, 1.95–12.28), and Child-Pugh B cirrhosis (vs. Child-Pugh A: HR: 2.54, 95% CI, 1.27–5.08).
Conclusions:
Recall patterns for patients with subcentimeter liver lesions on ultrasound varied widely. The low risk of PLC in these patients supports short-interval ultrasound in 3–6 months, although diagnostic CT/MRI may be warranted for high-risk subgroups such as those with elevated alpha-fetoprotein levels.

INTRODUCTION:
The outcomes of transjugular intrahepatic portosystemic shunt (TIPS) placement in patients with hepatic encephalopathy (HE) are controversial. We studied the relationship of pre-TIPS HE in patients undergoing TIPS for refractory ascites on all-cause mortality and development of post-TIPS HE.
METHODS:
A single-center retrospective comparison study was performed for patients undergoing TIPS for refractory ascites. Survival by history of pre-TIPS HE was demonstrated with Kaplan-Meier curves. Univariate and multivariate logistic regression analyses were performed to identify the predictors of post-TIPS clinical outcomes for patients with and without pre-TIPS HE.
RESULTS:
We identified 202 TIPS recipients (61% male, mean ± SD; age 59.1 ± 10.2 years; mean model for end-stage liver disease score 17.3 ± 6.9). Pre-TIPS HE did not predispose patients for increased all-cause mortality, increased risk of experiencing HE within 60 days, or increased risk of hospital admission for HE within 6 months. A multivariate analysis demonstrated that total bilirubin (odds ratio [OR] 1.03;
P
= 0.016) and blood urea nitrogen (OR 1.15;
P
= 0.002) were predictors for all-cause mortality within 6 months post-TIPS. Age ≥65 years (OR 3.92;
P
= 0.004), creatinine (OR 2.22;
P
= 0.014), and Child-Pugh score (OR 1.53;
P
= 0.006) were predictors for HE within 60 days post-TIPS. Predictors of intensive care admission for HE within 6 months post-TIPS included age ≥65 years (OR 8.84;
P
= 0.018), history of any admission for HE within 6 months pre-TIPS (OR 8.42;
P
= 0.017), and creatinine (OR 2.22;
P
= 0.015).
DISCUSSION:
If controlled, pre-TIPS HE does not adversely impact patient survival or clinical outcomes, such as development of HE within 60 days of TIPS or hospital admission for HE within 6 months. Patients may be able to undergo TIPS for refractory ascites despite a history of HE.
