<b><i>Purpose:</i></b> Microvascular invasion (MVI) is an important prognostic factor in patients with hepatocellular carcinoma (HCC). However, the reported results of magnetic resonance imaging (MRI) features for predicting MVI of HCC are variable and conflicting. Therefore, this meta-analysis aimed to identify the significant MRI features for MVI of HCC and to determine their diagnostic value. <b><i>Methods:</i></b> Original studies reporting the diagnostic performance of MRI for predicting MVI of HCC were identified in MEDLINE and EMBASE up until January 15, 2020. Study quality was assessed using QUADAS-2. A bivariate random-effects model was used to calculate the meta-analytic pooled diagnostic odds ratio (DOR) and 95% confidence interval (CI) for each MRI feature for diagnosing MVI in HCC. The meta-analytic pooled sensitivity and specificity were calculated for the significant MRI features. <b><i>Results:</i></b> Among 235 screened articles, we found 36 studies including 4,274 HCCs. Of the 15 available MRI features, 7 were significantly associated with MVI: larger tumor size (&#x3e;5 cm) (DOR = 5.2, 95% CI [3.0–9.0]), rim arterial enhancement (4.2, 95% CI [1.7–10.6]), arterial peritumoral enhancement (4.4, 95% CI [2.8–6.9]), peritumoral hypointensity on hepatobiliary phase imaging (HBP) (8.2, 95% CI [4.4–15.2]), nonsmooth tumor margin (3.2, 95% CI [2.2–4.4]), multifocality (7.1, 95% CI [2.6–19.5]), and hypointensity on T1-weighted imaging (T1WI) (4.9, 95% CI [2.5–9.6]). Both peritumoral hypointensity on HBP and multifocality showed very high meta-analytic pooled specificities for diagnosing MVI (91.1% [85.4–94.8%] and 93.3% [74.5–98.5%], respectively). <b><i>Conclusions:</i></b> Seven MRI features including larger tumor size, rim arterial enhancement, arterial peritumoral enhancement, peritumoral hypointensity on HBP, nonsmooth margin, multifocality, and hypointensity on T1WI were significant predictors for MVI of HCC. These MRI features predictive of MVI can be useful in the management of HCC.

It remains unclear whether the short-term benefits and long-term outcomes of laparoscopic liver resection (LLR) accrue to elderly patients with medical comorbidities. The aim of the present study was to compare the outcomes between LLR and open liver resection (OLR) in elderly patients (≥65 years) with solitary, treatment-naïve solitary hepatocellular carcinoma (HCC). From January 2013 to August 2017, 256 elderly patients with solitary treatment-naive HCC underwent liver resection. All patients were Child–Pugh class A and older than 65 years. The OLR and LLR groups contained 160 and 96 patients, respectively. The median tumor size in the OLR group was significantly larger than that in the LLR group (3.9 vs. 2.6 cm), but the tumor size did not differ between the two groups after matching. The median operation time, blood loss, transfusion rate, and postoperative complications in the OLR group did not differ from those in the LLR group, but the operation time in the LLR group was longer than that in the OLR group after matching. The median hospitalization in the LLR group was significantly shorter than that in the OLR group. Disease-free survival (DFS) in the LLR group was better than that in the OLR group before and after matching, but the difference was not significant. Patient survival (PS) in the LLR group was similar to that in the OLR group. LLR is feasible and safe for elderly patients with solitary, treatment-naïve HCC. The short- and long-term benefits of LLR are evident in geriatric oncological liver surgery patients.

Objective. To investigate the imaging features observed in preoperative Gd-EOB-DTPA-dynamic enhanced MRI and correlated with the presence of microvascular invasion (MVI) in hepatocellular carcinoma (HCC) patients. Methods. 66 HCCs in 60 patients with preoperative Gd-EOB-DTPA-dynamic enhanced MRI were retrospectively analyzed. Features including tumor size, signal homogeneity, tumor capsule, tumor margin, peritumor enhancement during mid-arterial phase, peritumor hypointensity during hepatobiliary phase, signal intensity ratio on DWI and apparent diffusion coefficients (ADC), T1 relaxation times, and the reduction rate between pre- and postcontrast enhancement images were assessed. Correlation between these features and histopathological presence of MVI was analyzed to establish a prediction model. Results. Histopathology confirmed that MVI were observed in 17 of 66 HCCs. Univariate analysis showed tumor size (p=0.003), margin (p=0.013), peritumor enhancement (p=0.001), and hypointensity during hepatobiliary phase (p=0.004) were associated with MVI. A multiple logistic regression model was established, which showed tumor size, margin, and peritumor enhancement were combined predictors for the presence of MVI (α=0.1). R2 of this prediction model was 0.353, and the sensitivity and specificity were 52.9% and 93.0%, respectively. Conclusion. Large tumor size, irregular tumor margin, and peritumor enhancement in preoperative Gd-EOB-DTPA-dynamic enhanced MRI can predict the presence of MVI in HCC.

e15657 Background: Microvascular invasion (MVI) is an important risk factor of recurrence for hepatocellular carcinoma (HCC). We aimed to explore the relationship of the number of sampling sites (NuSS) and sampling location with positive rate of MVI, and investigate cut-off values for NuSS. Methods: From May 2010 to Feb 2017, 910 HCC patients undergone hepatectomy with well-preserved tissue blocks were retrospectively enrolled. Associations between NuSS and positive rates of MVI were investigated. The thresholds of NuSS according to different factors were determined by Chow test and Breakpoints function, and validated prospectively in 118 patients. In validation cohort, MVI positive rates in different sampling locations were estimated. Results: The positive rates of MVI increased as NuSS increased ( P < 0.001). Tumor size and number were two factors influencing NuSS. A minimum of four, six, eight and eight sampling sites were required for detecting MVI in solitary tumors measuring 1.0-3.0 cm, 3.1-4.9 cm and ≥ 5.0 cm and multiple tumors. The positive rates of MVI as per developed thresholds were significantly higher in all the tumor subgroups of validation cohort than those in routine clinical practice in training cohort (46.7% vs. 20.6%, P= 0.048; 44.4% vs. 24.4%, P= 0.025; 73.3% vs. 50.3%, P= 0.004; 67.7% vs. 45.4%, P= 0.026). The positive rates of MVI in tumor interface were higher than those in proximal and distal paracancerous and normal liver parenchyma. Conclusions: The different thresholds of NuSS according to tumor size and number, and sampling distribution according to location provided evidences of standardized sample collection of liver cancer specimen for accurate MVI diagnosis.

Abstract Some doubts were generated during the reading of nomograms based on inflammatory biomarkers for preoperatively predicting tumor grade and microvascular invasion in stage I/II hepatocellular carcinoma (HCC). We would like to highlight and discuss with authors. First, neutrophil-lymphocyte ratio (NLR) and derived NLR (dNLR) should not be entered into multivariate analysis simultaneously. Second, authors should clarify how the cutoffs of these variables including lymphocyte-monocyte ratio (LMR), dNLR, age and tumor size were set. We insist that the type of variables should be consistent when we carry out the analysis and establish the nomogram. Last, we have to point out that Li et al.’s (Biosci. Rep. (2018), 38) study failed to validate nomograms using an independent dataset.

Purpose: To establish a valid prediction model to prognose the occurrence of microvascular invasion (MVI), and to compare the efficacy of anatomic resection (AR) or non-anatomic resection (NAR) for hepatocellular carcinoma (HCC).Methods: Two hundred twenty-eight patients with HCC who underwent surgical treatment were enrolled. Their hematological indicators, MRI imaging features, and outcome data were acquired.Result: In the multivariable analysis, alpha-fetoprotein &gt;15 ng/mL, neutrophil to lymphocyte ratio &gt;3.8, corona enhancement, and peritumoral hypointensity on hepatobiliary phase were associated with MVI. According on these factors, the AUROC of the predictive model in the primary and validation cohorts was 0.884 (95% CI: 0.829, 0.938) and 0.899 (95% CI: 0.821, 0.967), respectively. Patients with high risk of MVI or those with low risk of MVI but tumor size &gt;5 cm in the AR group were associated with a lower rate of recurrence and death than patients in the NAR group; however, when patients are in the state of low-risk MVI with tumor size &gt;5 cm, there is no difference in the rate of recurrence and death between AR and NAR.Conclusion: Our predictive model for HCC with MVI is convenient and accurate. Patients with high-risk of MVI or low-risk of MVI but tumor size &gt;5 cm executing AR is of great necessity.

15118 Background: It is quite important to predict postoperative recurrence or prognosis in the patients with hepatocellular carcinoma (HCC) before surgery. There have been few reports about the value of doubling time of preoperative serum a-fetoprotein (AFP) or protein induced by vitamin K absence (PIVKA-II) levels. Methods: Between January 2000 to December 2005, 160 consecutive HCC patients underwent hepatic resections in our institution. Serum AFP and PIVKA-II level was prospectively measured at least two points before surgery to calculate a doubling time. Clinical factors such as age, gender, BMI, etiology of hepatitis, degree of liver damage, gross tumor type, tumor size, tumor numbers, portal vein tumor thrombosis (PVTT), and AFP-L3 were concurrently investigated. Univariate and multivariate analyses were done to clarify predictive factors of postoperative recurrence and survival. Results: There were no relationship between preoperative levels and doubling time of both tumor markers. In univariate analysis, significant predictors of postoperative recurrence were AFP > 200 ng / ml, PIVKA-II > 200 mAU / ml, AFP-L3 > 10%, non-simple nodular type tumor, tumor size > 3 cm, multiple tumors, PVTT positive, and doubling time of AFP < 40 days. The significant prognostic factors were AFP > 200 ng / ml, HBs antigen positive, non-simple nodular type tumor, multiple tumors, PVTT positive, and doubling time of AFP < 40 days. In multivariate analysis, multiple tumors (odds ratio: 1.48), and doubling time of AFP < 40 days (odds ratio: 2.17) were significant predictors of recurrence. The significant prognostic factors were non-simple nodular type tumor (odds ratio: 6.41), multiple tumors (odds ratio: 7.62), and doubling time of AFP < 40 days (odds ratio: 6.49). Postoperative mean recurrence free survival time of HCC patients with doubling time of AFP < 40 days was only 2.8 months and mean survival time was 34 months. Conclusions: In HCC patients, doubling time of preoperative serum AFP level is useful to predict early recurrence and poor prognosis. Perioperative adjuvant therapy should be considered for such high risk patients. No significant financial relationships to disclose.
