427 Background: Official guidelines and retrospective studies have different view on the role of hepatic resection (HR) for patients with large (≥5 cm) multinodular (≥2) hepatocellular carcinoma (HCC) and those involving macrovascular invasion (MVI). We aim to evaluate the efficacy and its variation trend and the safety of HR for these patients in three tertiary care settings. Methods: A consecutive sample of 1,824 patients with Child-Pugh A liver function and large/multinodular HCC or involving MVI and who underwent initial HR were divided into four groups: large/multinodular HCC of the previous (2000-2004, n = 496) and recent five years (2005-2010, n = 765), involving MVI of the previous (n = 242) and recent five years (n = 321). Results: Among our patient sample, the hospital mortality was less than 5% and had a downward trend. Moreover, patients in recent five years have statistically significant longer survival time. Among patients with large/multinodular HCC, patients in recent five years showed a significantly better overall survival than those in previous five years at 1-year (92% vs. 84%), 3-year (69% vs. 61%), and 5-year (45% vs. 40%) (P = 0.004). Moreover, among patients involving MVI, overall survival in recent five years was significantly higher at 1-year (83% vs. 78%), 3-year (50% vs. 41%), and 5-year (25% vs. 17%) (P= 0.033). However, the disease-free survival of recent five years was only slightly higher than that of the previous five years in the two subgroups. Conclusions: HR offers good overall survival for patients with resectable large/multinodular HCC or those involving MVI and with preserved liver function. Outcomes have tended to improve in recent decade.

Long-term surgical outcomes after hepatic resection for hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) in patients who achieved a sustained virological response (SVR) to interferon (IFN) therapy remain inconclusive. Clinical records of 277 patients who underwent hepatic resection for HCV-related early stage HCC (met the Milan criteria) between 1993 and 2012 were retrospectively reviewed. Thirty-seven patients achieved the SVR during HCC detection (pre-SVR group), whereas 23 achieved SVR using adjuvant interferon therapy after hepatic resection (post-SVR group). The control group included remaining 217 patients. We investigated the SVR effects on surgical outcomes. Disease-free survival (DFS) rates at 5/10/15 years after hepatic resection were significantly greater in the pre and post-SVR groups than in the control group (46/30/30per cent and 61/36/27 per cent vs 23/7/7 per cent, respectively; P < 0.001). Overall survival (OS) rates at 10/15 years after hepatic resection were better in the pre- and post-SVR groups than in the control group (68/68 percent and 78/78 per cent vs 13/11 per cent, respectively; P < 0.001). On multivariate analysis, pre- and post-SVR were independent factors for no recurrence (pre-SVR: hazard ratio (HR), 0.48, P = 0.002; post-SVR: HR, 0.41, P = 0.001) and improved survival (pre-SVR: HR, 0.36, P = 0.002; post-SVR: HR, 0.122, P < 0.001). Achievement of SVR in patients with HCV-related HCC was associated with long-term disease-free survival and OS after hepatic resection.

Abstract Background Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) is an infrequent type of primary liver cancer that comprises hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). This study investigated the clinicopathological features and prognosis among cHCC-CC, HCC, and CC groups. Methods We prospectively collected the data of 608 patients who underwent surgical resection for liver cancer between 2011 and 2018 at E-Da Hospital, I-Shou University, Kaohsiung, Taiwan. Overall, 505 patients with cHCC-CC, HCC, and CC were included, and their clinicopathological features, overall survival (OS), and recurrence were recorded. OS and recurrence rates were analyzed using the Kaplan–Meier analysis. Results In the entire cohort, the median age was 61 years and 80% were men. Thirty-five (7.0%) had cHCC-CC, 419 (82.9%) had HCC, and 51 (10.1%) had CC. The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. OS was significantly lower in the cHCC-CC group than in the HCC group but was not significantly higher in the cHCC-CC group than in the CC group. The median OS of cHCC-CC, HCC, and CC groups was 50.1 months [95% confidence interval (CI): 38.7–61.2], 62.3 months (CI: 42.1–72.9), and 36.2 months (CI: 15.4–56.5), respectively. Cumulative OS rates at 1, 3, and 5 years in cHCC-CC, HCC, and CC groups were 88.5%, 62.2%, and 44.0%; 91.2%, 76.1%, and 68.0%; and 72.0%, 48.1%, and 34.5%, respectively. After propensity score matching (PSM), OS in the cHCC-CC group was not significantly different from that in the HCC or CC group. However, OS was significantly higher in the HCC group than in the CC group before and after PSM. Furthermore, the disease-free survival was not significantly different among cHCC-CC, HCC, and CC groups before and after PSM. Conclusion The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. The OS rate was significantly lower in the cHCC-CC group than the HCC group. However, after PSM, OS and disease-free survival in the cHCC-CC group were not significantly different from those in the HCC or CC group.

AbstractSoil liquefaction is a phenomenon through which saturated soil completely loses its strength and hardness and behaves the same as a liquid due to the severe stress it entails. This stress can be caused by earthquakes or sudden changes in soil stress conditions. Many empirical approaches have been proposed for predicting the potential of liquefaction, each of which includes advantages and disadvantages. In this paper, a novel prediction approach is proposed based on an artificial neural network (ANN) to adequately predict the potential of liquefaction in a specific range of soil properties. To this end, a whole set of 100 soil data is collected to calculate the potential of liquefaction via empirical approaches in Tabriz, Iran. Then, the results of the empirical approaches are utilized for data training in an ANN, which is considered as an option to predict liquefaction for the first time in Tabriz. The achieved configuration of the ANN is utilized to predict the liquefaction of 10 other data sets for validation purposes. According to the obtained results, a well-trained ANN is capable of predicting the liquefaction potential through error values of less than 5%, which represents the reliability of the proposed approach.
