RESUMO
BACKGROUND: The therapeutic value of repeat hepatic resection (rHR) or radiofrequency ablation (RFA) for recurrent hepatocellular carcinoma (HCC) is unknown. This study aimed to investigate the safety and efficacy of rHR or RFA. METHODS: This was a retrospective multicentre study of patients with recurrent HCC within the Milan criteria who underwent rHR or RFA at nine university hospitals in China and Italy between January 2003 and January 2018. Survival after rHR or RFA was examined in unadjusted analyses and after propensity score matching (1 : 1). RESULTS: Of 847 patients included, 307 and 540 underwent rHR and RFA respectively. Median overall survival was 73.5 and 67.0 months after rHR and RFA respectively (hazard ratio 1.01 (95 per cent c.i. 0.81 to 1.26)). Median recurrence-free survival was longer after rHR versus RFA (23.6 versus 15.2 months; hazard ratio 0.76 (95 per cent c.i. 0.65 to 0.89)). These results were confirmed after propensity score matching. RFA was associated with lower morbidity of grade 3 and above (0.6 versus 6.2 per cent; P < 0.001) and shorter hospital stay (8.0 versus 3.0 days, P < 0.001) than rHR. CONCLUSION: rHR was associated with longer recurrence-free survival but not overall survival compared with RFA.

There is no consensus about factors that increase risk of hepatocellular carcinoma (HCC) among patients with chronic hepatitis B who have achieved seroclearance of hepatitis B surface antigen (HBsAg). To assess the available evidence about risk factors for HCC after HBsAg seroclearance, Scopus, EMBASE, PubMed and Cochrane Library databases were systematically searched for relevant studies published through 15 September 2017. A total of 28 studies involving more than 105 411 patients with chronic hepatitis B were included. HBsAg seroclearance occurred spontaneously in 7656, while it occurred after interferon or nucleos(t)ide analogue therapy in 1248. The rate of HBsAg seroclearance was 6.77%. Incidence of HCC was significantly lower among patients who experienced HBsAg seroclearance than among those who remained HBsAg-positive (1.86% vs 6.56%, P < .001). Risk factors of HCC occurrence included cirrhosis (incidence with vs without: 9.51% vs 1.66%), male gender (2.34% vs 0.64%) and age ≥ 50 year at HBsAg seroclearance (2.34% vs 0.63%) (all P < .001). The available evidence suggests that HCC can develop at a low rate after HBsAg seroclearance, so periodic surveillance is recommended, especially for male patients, patients with cirrhosis and patients who experience HBsAg seroclearance when at least 50 years old.

BACKGROUND: The Child-Pugh (CP) score is used widely to assess liver function and predict postoperative outcomes in patients with hepatocellular carcinoma (HCC). Recently, the albumin-bilirubin (ALBI) score has been validated as a predictor of overall survival in these patients. This study aimed to compare the ability of the ALBI and CP scores to predict outcomes in patients with HCC after liver resection with curative intent. METHODS: Consecutive patients who underwent liver resection with curative intent for HCC between January 2007 and July 2013 were included in this retrospective study. The performance of the ALBI score in predicting postoperative liver failure (PHLF) and long-term survival was compared with that of the CP score. RESULTS: A total of 1242 patients were enrolled. Of these, 166 (13·4 per cent) experienced PHLF. The area under the receiver operating characteristic (ROC) curve of the ALBI score for predicting PHLF was greater than that of the CP score (0·723 versus 0·607; P < 0·001). Similar to findings for CP grade, the incidence and severity of PHLF increased with increasing ALBI grade. The ALBI grade stratified patients into at least two distinct overall survival cohorts (P < 0·001), whereas the CP grade did not. The ALBI grade also classified patients with CP grade A disease into two distinct overall survival cohorts (P < 0·001), and overall survival rates in the group with poorer survival were similar to those in the majority of patients with CP grade B disease. Both CP and ALBI scores had low power in predicting disease-free survival. CONCLUSION: The ALBI grade predicted PHLF and overall survival in patients with HCC undergoing liver resection with curative intent more accurately than the CP grade.

Objective: To compare the efficacy of hepatic resection (HR) in patients with Barcelona Clinical Liver Cancer (BCLC) Stage B hepatocellular carcinoma (HCC) and examine how that efficacy has changed over time in a large medical center. Methods: A consecutive sample of 918 patients with preserved liver function and large and/or multinodular HCC who were treated by initial HR were divided into three groups: those with a single tumor ≥5 cm in diameter (n=582), 2-3 tumors with a maximum diameter>3 cm (n=223), or>3 tumors of any diameter (n=113). Hospital mortality and overall survival (OS) in each group were compared for the years 2001-2007 and 2008-2013. Results: Patients with >3 tumors showed the highest incidence of hospital mortality of all groups (P<0.05). Kaplan-Meier survival analysis showed that OS varied across the three groups as follows: single tumor>2-3 tumors >3+ tumors (all P<0.05). OS rate at 5 years ranged from 24% to 41% in all three groups for the period 2001-2007, and from 35% to 46% for the period 2008-2013. OS was significantly higher during the more recent 6-year period in the entire patient population, those with single tumor, and those with 3+ tumors (all P<0.05). However, in patients with 2-3 tumors, OS was only slightly higher during the more recent 6-year period (P=0.084). Conclusions: Prognosis of three types of HCC was different. Patients with >3 tumors show the highest hospital mortality and lowest OS after HR. OS has been improving for all three types of HCC at our medical center as a consequence of improvements in surgical technique and perioperative management.

OBJECTIVE: This study reviewed the distribution of each tumor stage and each type of initial treatment modality among patients with primary hepatocellular carcinoma (HCC) treated at a tertiary tumor hospital between January 2003 and October 2013. METHODS: Baseline data of patients with primary hepatocellular carcinoma treated between January 2003 and October 2013 were retrospectively collected. Tumor stage was determined according to the Barcelona Clinic Liver Cancer (BCLC) staging system and Hong Kong Clinic Liver Cancer (HKLC) staging system. RESULTS: A total of 6241 patients with primary hepatocellular carcinoma were included in the analysis. In accordance with the BCLC, 28.9% of patients were in stage 0/A, 16.2% in stage B, 53.6% in stage C, and 1.3% in stage D. According to the HKLC stage system, 8.4% patients were in stage I, 1.5% in stage IIa, 29.0% in stage IIb, 10.0% in stage IIIa, 33.6% in stage IIIb, 3.4% in stage IVa, 2.5% in stage IVb, 0.2% in stage Va, and 11.4% in stage Vb. Treatment modalities applied to this patient group were as follows: 33.3% of patients underwent hepatic resection, 36.7% underwent transarterial chemoembolization (TACE), 2.2% underwent radiotherapy, 0.9% underwent local ablated therapy, 8.8% underwent systemic chemotherapy, 4.2% underwent traditional herbal medicine therapy, 0.1% underwent targeted drug therapy, and 13.8% received no treatment. Hepatic resection was the most frequent therapy for patients with BCLC 0/A/B disease, and TACE was the initial therapy for patients with BCLC C disease. In the Hong Kong Clinic Liver Cancer staging system, the main treatments for HKLC I to IIIb disease is hepatic resection and TACE. Systemic chemotherapy was the initial therapy for patients with HKLC IVa/IVb disease. Most HKLC Va/Vb patients received traditional Chinese medicine treatment. CONCLUSION: Prevalence of stage BCLC B and C disease was high among our hepatocellular carcinoma patients. In Hong Kong Clinic Liver Cancer staging system, HKLC I to IIIb disease was high among our HCC patients. Hepatic resection and TACE are initial therapies.

AIMS: Numerous postoperative therapies for preventing recurrence of hepatocellular carcinoma (HCC) have been reported, but their efficacy remains controversial and knowledge about adverse effects is limited. A systematic review of randomized controlled trials (RCTs) was performed to gain a comprehensive picture of the efficacy and risks of these therapies. METHODS: MEDLINE, EMBASE and the Cochrane Library were systematically searched through July 2011. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated. RESULTS: A total of 2989 patients from 28 RCTs involving 10 postoperative therapies were included. For interferon therapy, the estimated RR for the 2-year recurrence rate was 0.84 (95% CI 0.73-0.97, P = 0.02) and the overall survival (OS) was 1.15 (95% CI 1.07-1.22, P < 0.001). Postoperative therapy with the vitamin K2 analog did not lead to a significant reduction in the 1-year recurrence rate, with a pooled RR of 0.60 (95% CI 0.28-1.27, P = 0.18). However, it did slightly improve the 1-year OS, with a pooled RR of 1.03 (95% CI 1.00-1.05, P = 0.03). Transarterial chemotherapy with or without embolization, adoptive immunotherapy and heparanase inhibitor PI-88 therapy may delay tumor recurrence. The effects of acyclic retinoid, lipiodol-iodine-131 and tumor vaccine treatment were promising but require further study. All postoperative therapies except interferon administered intramuscularly were well tolerated by the majority of patients. CONCLUSIONS: Use of adjuvant interferon is definitely associated with an increase in OS. Postoperative therapies involving acyclic retinoid, lipidol-iodine-131, or tumor vaccine may improve the OS of patients with HCC after curative treatment.
