Introduction: We evaluated the radiologic response rate of combined transarterial chemoembolization (TACE) plus radiotherapy (RT) in treatment-naïve patients with liver-confined hepatocellular carcinoma (HCC) with macroscopic vascular invasion (MVI) and analyzed its clinical importance in overall survival (OS) outcomes. Methods: Patients who were treated with TACE plus RT as a first-line treatment for HCC with MVI between January 2010 and December 2015 were retrospectively reviewed. Radiologic response was assessed according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST) at 2- and 4-months after completion of RT. Landmark analysis at 2- and 4-months and time-dependent Cox regression analysis using response as a time-dependent covariate were performed for univariable and multivariable analyses. Results: The 2-month landmark analysis included 427 patients, and the 4-month landmark analysis included 355 patients after excluding patients without imaging studies for response evaluation at 4 months. Radiologic responses were observed in 210 (49.2%) patients at 2 months and 181 (51.8%) at 4 months. In multivariable analyses, radiologic response was identified as an independent prognosticator for OS at 2 months (median OS: responders, 23.1 months vs. non-responders, 8.0 months; hazard ratio [HR], 3.194; P < 0.001) and 4 months (median OS: responders, 26.5 months vs. non-responders, 9.3 months; HR, 4.534; P < 0.001). Conclusion: Radiologic response assessed by mRECIST was a significant prognostic factor for OS in patients with advanced-stage HCC showing MVI treated with combined TACE plus RT.

Wnt5a Expression

573 Background: Wnt signaling pathway includes canonical pathway and non-canonical pathway. Wnt/β-Catenin pathway as canonical pathway is associated with the development of hepatocellular carcinoma (HCC). On the other hand, the association between aberrant activation of non-canonical pathway activated by Wnt5a and tumor progression of HCC is not well-known. We investigated the significance of the expression of Wnt5a in HCC. Methods: Immunohistochemical staining of Wnt5a was performed on the specimen of 243 patients who underwent hepatic resection for HCC. We investigated whether the expression of Wnt5a correlated with the clinicopathological factors, survival, and recurrence in HCC patients. The expression of Wnt5a in human HCC cell lines HLE, HLF, HepG2 and Huh7 was investigated by western blotting. The effects of overexpression or knockdown of Wnt5a on cell lines were evaluated by proliferation assay and invasion assay and changes in epithelial mesenchymal transition (EMT) related molecules were studied by western blotting. Results: The Wnt5a expression was positive in 63 patients (25.9%) and negative in 180 patients (74.1%). The Wnt5a negative was significantly associated with poorly differentiation (P = 0.003) and vascular invasion positive (P = 0.046). By univariate analysis, Wnt5a negative (P = 0.020) was identified as a significant prognostic factor of OS. Multivariate analysis of OS showed that Wnt5a negative (HR 1.895, 95% CI 1.053-3.409, P = 0.033) was identified as an independent prognostic factor. In the HCC cell lines, the Wnt5a expression was lower in HLE and HLF than in HepG2 and Huh7. Knockdown of Wnt5a by shRNA increased the proliferation and invasiveness in Huh7 with high expression of Wnt5a. As a result, the expression of E-cadherin decreased. In HLF with low expression of Wnt5a, overexpression of Wnt5a inhibited the invasiveness and the expression of vimentin decreased. Conclusions: Wnt5a negative was associated with poorly differentiation and vascular invasion, and was independent poor prognostic factor in HCC patients. Wnt5a may be a tumor suppressor involved in EMT mediated changes of invasiveness.

Macroscopic Vascular Invasion

Stereotactic body radiotherapy (SBRT) has shown promising results in the control of macroscopic vascular invasion in patients with hepatocellular carcinoma (HCC); however, its efficacy in comparison to sorafenib when combined with transarterial chemoembolization (TACE) remains to be determined. Between 2009 and 2017, 77 HCC patients with macroscopic vascular invasion receiving TACE–SBRT or TACE–sorafenib combination therapies were enrolled. The best treatment responses, overall survival (OS), and progression-free survival (PFS) of the two treatment arms were compared. Of the patients enrolled, 26 patients (33.8%) received TACE–SBRT treatment, and 51 (66.2%) received TACE–sorafenib treatment. The patients in the TACE–SBRT group were more frequently classified as elder in age (p = 0.012), having recurrent disease (p = 0.026), and showing lower rates of multiple hepatic lesions (p = 0.005) than patients in TACE–sorafenib group. After propensity score matching (PSM), 26 pairs of well-matched HCC patients were selected; patients in the TACE–SBRT group showed better overall response rates in trend compared to those in the TACE–sorafenib group. The hazard ratio (HR) of OS to PFS for the TACE–SBRT approach and the TACE–sorafenib approach was 0.36 (95% CI, 0.17–0.75; p = 0.007) and 0.35 (95% CI, 0.20–0.62; p < 0.001), respectively. For HCC patients with macrovascular invasion, TACE plus SBRT could provide improved OS and PFS compared to TACE–sorafenib therapy.

Objective This study was performed to determine whether transarterial chemoembolization (TACE) plus multi-imaging–guided radiofrequency ablation (MIG-RFA) can completely eliminate 3.1- to 5.0-cm hepatocellular carcinoma (HCC) nodules and identify factors that may influence the complete elimination rate (CER) of this therapy. Methods Patients who underwent TACE+MIG-RFA for initial treatment of HCC from January 2008 to January 2016 were retrospectively reviewed. In total, 162 patients with 216 HCC nodules (3.1–5.0 cm) were enrolled. TACE was performed first; MIG-RFA was performed 2 to 4 weeks later. Contrast-enhanced computed tomography was performed 1, 3, 6, and 12 months after TACE+MIG-RFA. If tumor enhancement was not detected by the end of the 12-month follow-up, the lesion was considered completely eliminated. Additional TACE+MIG-RFA was performed for residual lesions. The CER was calculated 12 months after the last therapy. Factors that may influence the CER were analyzed. Results In total, 207 (95.8%) nodules showed no residual lesions and were completely eliminated after one or more TACE+MIG-RFA sessions. Nine (4.2%) nodules were incompletely eliminated even with repeated TACE+MIG-RFA. Tumor location was the only significant prognostic factor influencing the CER. Conclusions TACE+MIG-RFA can eliminate 3.1- to 5.0-cm HCC nodules; the tumor location may affect the treatment outcome.
