Hepatic resection (HR) and liver transplantation (LT) are surgical treatment options for hepatocellular carcinoma (HCC). However, it is clinically impossible to perform a randomized, controlled study to determine the usefulness of these treatments. The present study compared survival rates and recurrence rates of HR versus living donor LT (LDLT) for HCC by using the propensity score method. Between January 1999 and August 2012, 936 patients (732 HR, 204 LDLT) underwent surgical therapy for HCC in our center. Using the propensity score matching, 80 well-balanced patients were defined. The 1- and 5-year overall survival rates were 90% and 53% in the HR group and 82% and 63% in the LT group, respectively. They were not significantly different between the two groups. The odds ratio estimated using the propensity score matching analysis was 0.842 (P=0.613). The 1- and 5-year recurrence rates were significantly lower in the LT group (9% and 21%) than in the HR group (43% and 74%) (P<0.001), and the odds ratio was 0.214 (P=0.001). In conclusion, HR should be considered a valid alternative to LDLT taking into consideration the risk for the living donor based on the results of this propensity score-matching study.

Abstract Background: The benefits of surgical resection (SR) for various Barcelona Clinic Liver Cancer (BCLC) stages of hepatocellular carcinoma (HCC) remain unclear. We investigated the risk factors of overall survival (OS) and survival benefits of SR over nonsurgical treatments in patients with HCC of various BCLC stages.Methods: Overall, 2316 HCC patients were included, and their clinicopathological data and OS were recorded. OS was analyzed by the Kaplan-Meier method and Cox regression analysis. Propensity score matching (PSM) analysis was performed.Results: In total, 66 (2.8%), 865 (37.4%), 575 (24.8%) and 870 (35.0%) patients had BCLC stage 0, A, B, and C disease, respectively. Furthermore, 1302 (56.2%) of all patients, and 37 (56.9%), 472 (54.6%), 313 (54.4%) and 480 (59.3%) of patients with BCLC stage 0, A, B, and C disease, respectively, died. The median follow-up duration time was 20 (range 0-96) months for the total cohort and was subdivided into 52 (8-96), 32 (1-96), 19 (0-84), and 12 (0-79) months for BCLC stages 0, A, B, and C cohorts, respectively. The risk factors for OS were 1) SR and cirrhosis; 2) SR, cirrhosis, and Child-Pugh (C-P) class; 3) SR, hepatitis B virus (HBV) infection, and C-P class; and 4) SR, HBV infection, and C-P class for the BCLC stage 0, A, B, and C cohorts, respectively. Compared to non-SR treatment, SR resulted in significantly higher survival rates in all cohorts. The 5-year OS rates for SR vs non-SR were 44.0% vs 28.7%, 72.2% vs 42.6%, 42.6% vs 36.2, 44.6% vs 23.5%, and 41.4% vs 15.3% (all p-values<0.05) in the total and BCLC stage 0, A, B, and C cohorts, respectively. After PSM, SR resulted in significantly higher survival rates compared to non-SR treatment in various BCLC stages.Conclusion: SR conferred significant survival benefits to patients with HCC of various BCLC stages and should be considered a recommended treatment for select HCC patients, especially patients with BCLC stage B and C disease.

e21087 Background: Chemoradiotherapy (CRT) followed by consolidation treatment with the PD-L1 Inhibitor durvalumab is the new standard of care for inoperable stage III NSCLC. The present study compares outcome of patients treated with CRT alone to those treated with additional concurrent and/or sequential immune check-point inhibition (CRT-IO) using propensity-score matching analysis (PSM). Methods: PSM was performed with retro- and prospectively collected data of patients treated with CRT or CRT-IO (consolidation with durvalumab/concurrent and consolidation with nivolumab). Overall survival (OS), progression free survival (PFS) and time to loco-regional recurrence (defined as progression in the mediastinum and ipsilateral lung) were calculated from last day of thoracic irradiation. Results: Sixty-two (37%) of 166 treated patients were successfully matched; 31 received CRT and 31 CRT-IO. 18F-FDG-PET/CT for treatment planning was performed in 97% and cranial contrast enhanced MRI in 81% of patients. PSM was based on age, gender, PTV volume, histology, T- and N-stage. 36 and 51% vs. 42 and 46% of patients had T4- and N3-disease in the CRT and CRT-IO cohorts, respectively. All patients were irradiated to a total dose of at least 60Gy (EQD2). 90% of patients received two cycles of concomitant platinum-based chemotherapy (CRT: 82%, CRT-IO 96%). The median follow-up for 62 patients was 17.3 (range: 1.7-96.0) months. Median PFS was 7.1 (95%CI 2.2-12.1) months in CRT vs. 13.8 (95%CI 13.1-14.5) in CRT-IO patients (p = 0.004). Twelve-month PFS rates were 30% and 55% in the CRT and the CRT-ICI cohort, respectively. Median time to loco-regional recurrence was 15.3 months for CRT vs. not reached for CRT-IO patients (p = 0.050). 12-month loco-regional recurrence rates were 43% vs. 22%; 6- and 12-month brain metastases rates after completion of radiotherapy in the CRT vs. CRT-ICI cohort were 8% and 26% vs. 0% and 20%, respectively. Median OS was 19.1 (8.4-29.8 95%CI) months for CRT and not reached for CRT-IO patients (p < 0.001). 12-month survival rates were 62% and 93% in the CRT and CRT-IO cohort, respectively. Conclusions: The addition of concurrent and/or sequential IO to CRT led to an impressive improvement of loco-regional control, PFS and OS in the matching cohorts.

Background/Purpose: Laparoscopic hepatic resection (LH) for hepatocellular carcinoma (HCC) has gradually gained ground as a safe and minimally invasive treatment, although LH for cirrhotic patients remains challenging. Methods: Between January 2007 and August 2014, 28 and 57 patients with histologically proven cirrhosis (histological activity index, fibrosis score 4) underwent pure LH and open hepatic resection (OH; less than segmentectomy), respectively, for peripheral HCC ≤5 cm. To correct the difference in clinicopathological factors, including difficulty scores, between the two groups, propensity score matching was used at a 1:1 ratio, which resulted in a comparison of 20 patients per group. We compared the short- and long-term outcomes of LH and OH to investigate the efficacy of LH. Results: Clinicopathological variables, including difficulty scores, were well balanced between the two groups. The incidence of complications and mean intraoperative blood loss were lower in the LH group than the OH group (0 vs. 45% and 180 vs. 440 ml, p = 0.001 and 0.04, respectively). The 3-year disease-free survival rate was 42% in the LH group and 30% in the OH group (p = 0.533), whereas the 5-year overall survival rates were 46 and 60%, respectively (p = 0.606). Conclusions: LH is a safe and effective treatment option for cirrhotic patients with HCC in terms of intraoperative blood loss and morbidity.

Frailty including physical inactivity is associated with the survival of patients with hepatocellular carcinoma (HCC). We aimed to investigate the effects of in-hospital exercise on frailty in patients with HCC. This was a multi-center observational study. Patients with HCC were classified into exercise (n = 114) and non-exercise (n = 67) groups. The exercise group was treated with a mixture of aerobic and resistance exercises (20–40 min/day, median four days). Frailty was assessed using the liver frailty index (LFI). Factors for changes in LFI were examined by multivariate and decision-tree analyses. The factors were also examined after propensity score matching. During hospitalization, LFI was significantly improved in the exercise group compared to the non-exercise group (ΔLFI −0.17 vs. −0.02, p = 0.0119). In multivariate analysis, exercise (odds ratio (OR) 2.38, 95% confidence interval (CI) 1.240–4.570, p = 0.0091) and females (OR 2.09; 95%CI, 1.062–4.109; p = 0.0328) were identified as independent factors for the improvement of LFI. In the decision-tree analysis, exercise was identified as an initial classifier associated with the improvement of LFI. Similar findings were also seen in the propensity score matching analyses. We demonstrated that in-hospital exercise improved frailty in patients with HCC. Thus, in-hospital exercise may be beneficial for improving physical function in patients with HCC.
