This article, published in the British Journal of Surgery, examines the importance of nodular number in predicting the prognosis of patients with intermediate-stage hepatocellular carcinoma (HCC) who undergo hepatectomy. The study, conducted at multiple hepatobiliary centers in China, Italy, and the USA, analyzed data from HCC patients who had undergone curative-intent hepatic resection between 2008 and 2018. The findings indicate that patients with three or more tumor nodules had lower overall survival and recurrence-free survival rates compared to those with two nodules. The study suggests that nodular number should be considered when predicting long-term prognosis after hepatic resection for intermediate-stage HCC. However, further research is needed to validate these findings. The study was supported by various funding sources and the authors have no conflicts of interest. [Extracted from the article]

The Eastern Staging System, which was specially developed for patients undergoing surgical resection for hepatocellular carcinoma (HCC), has been proposed for more than ten years. To prospectively validate the predictive accuracy of the Eastern staging on long-term survival after HCC resection. Patients who underwent hepatectomy for HCC from 2011 to 2020 at 10 Chinese hospitals were identified from a prospectively collected database. The survival predictive accuracy was evaluated and compared between the Eastern Staging with six other staging systems, including the JIS, BCLC, Okuda, CLIP, 8th AJCC TNM, and HKLC staging. Among 2365 patients, the 1-, 3-, and 5-year overall survival rates were 84.2%, 64.5%, and 52.6%, respectively. Among these seven staging systems, the Eastern staging was associated with the best monotonicity of gradients (linear trend χ2: 408.5) and homogeneity (likelihood ratio χ2: 447.3), and the highest discriminatory ability (the areas under curves for 1-, 3-, and 5-year mortality: 0.776, 0.787, and 0.768, respectively). In addition, the Eastern staging was the most informative staging system in predicting survival (Akaike information criterion: 2982.33). Using a large multicenter prospectively collected database, the Eastern Staging was found to show the best predictive accuracy on long-term overall survival in patients with resectable HCC than the other 6 commonly-used staging systems.

Background and aims: Although adjuvant transcatheter arterial chemoembolization (TACE) for resected hepatocellular carcinoma (HCC) may improve survival for some patients, identifying which patients can benefit remains challenging. The present study aimed to construct a survival prediction calculator for individualized estimating the net survival benefit of adjuvant TACE for patients with resected HCC. Methods: From a multicenter database, consecutive patients undergoing curative resection for HCC were enrolled and divided into the developing and validation cohorts. Using the independent survival predictors in the developing cohort, two nomogram models were constructed for patients with and without adjuvant TACE, respectively, which predictive performance was validated internally and externally by measuring concordance index (C-index) and calibration. The difference between two estimates of the prediction models was the expected survival benefit of adjuvant TACE. Results: A total of 2514 patients met the inclusion criteria for the study. The nomogram prediction models for patients with and without adjuvant TACE were, respectively, built by incorporating the same eight independent survival predictors, including portal hypertension, Child–Pugh score, alpha-fetoprotein level, tumor size and number, macrovascular and microvascular invasion, and resection margin. These two prediction models demonstrated good calibration and discrimination, with all the C-indexes of greater than 0.75 in the developing and validation cohorts. A browser-based calculator was generated for individualized estimating the net survival benefit of adjuvant TACE. Conclusions: Based on large-scale real-world data, an easy-to-use online calculator can be adopted as a decision aid to predict which patients with resected HCC can benefit from adjuvant TACE.

Aging of the population and prolonged life expectancy have significantly increased the number of elderly patients undergoing hepatectomy for hepatocellular carcinoma (HCC). However, potential benefits, especially long-term oncologic outcomes of hepatectomy for elderly patients with HCC remain unclear. Patients treated with curative-intent hepatectomy for HCC in 8 Chinese hospitals were enrolled. Patients were divided into the elderly (≥70 years old) and younger (<70 years old) groups. Overall survival (OS), cancer-specific survival (CSS), and time-to-recurrence (TTR) were compared. Risk factors of CSS and TTR were evaluated by univariable and multivariable competing-risk regression analyses. Of 2134 patients, 259 (12.1%) and 1875 (87.9%) were elderly and younger aged, respectively. Postoperative 30-day and 90-day mortality was comparable among elderly and younger patients. Compared with younger patients, the elderly had a worse 5-year OS (49.4% vs. 55.3%, P = 0.032), yet a better 5-year CCS (74.5% vs. 61.0%, P = 0.005) and a lower 5-year TTR (33.7% vs. 44.9%, P < 0.001), respectively. Multivariable analyses identified that elder age was independently associated with more favorable CSS (HR 0.74, 95%CI 0.58–0.90, P = 0.011) and TTR (0.69, 0.53–0.88, P < 0.001) but was not associated with OS (P = 0.136). Age by itself is not a contraindication to surgery, and selected elderly patients with HCC can benefit from hepatectomy. Compared with younger patients, elderly patients have noninferior oncologic outcomes following hepatectomy for HCC. [ABSTRACT FROM AUTHOR]

A clear definition of "early recurrence" after hepatocellular carcinoma (HCC) resection is still lacking. This study aimed to determine the optimal cutoff between early and late HCC recurrence, and develop nomograms for pre- and postoperative prediction of early recurrence. Patients undergoing HCC resection were identified from a multi-institutional Chinese database. Minimum P -value approach was adopted to calculate optimal cut-off to define early recurrence. Pre- and postoperative risk factors for early recurrence were identified and further used for nomogram construction. The results were externally validated by a Western cohort. Among 1501 patients identified, 539 (35.9%) were recurrence-free. The optimal length to distinguish between early (n = 340, 35.3%) and late recurrence (n = 622, 64.7%) was 8 months. Multivariable logistic regression analyses identified 5 preoperative and 8 postoperative factors for early recurrence, which were further incorporated into preoperative and postoperative nomograms (C-index: 0.785 and 0.834). The calibration plots for the probability of early recurrence fitted well. The nomogram performance was maintained using the validation dataset (C-index: 0.777 for preoperative prediction and 0.842 for postoperative prediction). An interval of 8 months was the optimal threshold for defining early HCC recurrence. The two web-based nomograms have been published to allow accurate pre- and postoperative prediction of early recurrence. These may offer useful guidance for individual treatment or follow up for patients with resectable HCC. [ABSTRACT FROM AUTHOR]

Background: The incidence of hepatocellular carcinoma (HCC) in non-alcoholic fatty liver disease (NAFLD) is increasing worldwide. Higher perioperative risks may be anticipated due to underlying steatohepatitis, while long-term outcomes after liver resection are unknown. We sought to investigate outcomes after liver resection for NAFLD-HCC versus hepatitis B virus (HBV)-HCC using propensity score matching (PSM).Methods: Consecutive patients who underwent liver resection for HCC between 2003 and 2014 were identified from a multicenter database. Patients with NAFLD-HCC were matched one-to-one to patients with HBV-HCC.Results: Among 1483 patients identified, 96 (6.5%) had NAFLD-HCC and 1387 (93.5%) had HBV-HCC. Patients with NAFLD-HCC were older (median age 57 vs. 50 years), more often overweight (50.0% vs. 37.5%), less often to have cirrhosis (30.2% vs. 72.5%) and liver dysfunction (Child-Pugh B: 4.2% vs. 10.7%), had larger tumor size (median 7.2 vs. 6.2 cm) yet had better tumor differentiation (27.1% vs. 17.6%) compared with patients with HBV-HCC (all P < 0.05). Perioperative mortality and morbidity were comparable between the two groups (1.0% vs. 1.4% and 20.8% vs. 23.2%, both P > 0.05). No differences were noted in median OS and RFS among patient with NAFLD-HCC versus HBV-HCC before or after PSM.Conclusion: While patients with NAFLD-HCC had different clinical characteristics than patients with HBV-HCC, liver resection resulted in similar perioperative outcomes and comparable OS and RFS among patients with NAFLD-HCC and HBV-HCC.

The resection margin (RM) status and microscopic vascular invasion (MVI) are known prognostic factors for hepatocellular carcinoma (HCC). An enhanced understanding of their impact on long-term prognosis is required to improve oncological outcomes. Using multi-institutional data, the different impact of the RM status (narrow, <1 cm, or wide, ≥1 cm) and MVI (positive or negative) on overall survival (OS) and recurrence-free survival (RFS) after curative liver resection of solitary HCC without macrovascular invasion was analyzed. In 801 patients, 306 (38%) had a narrow RM and 352 (44%) had positive MVI. The median OS and RFS were 109.8 and 74.8 months in patients with wide RM & negative MVI, 93.5 and 53.1 months with wide RM & positive MVI, 79.2 and 41.6 months with narrow RM & negative MVI, and 69.2 and 37.5 months with narrow RM & positive MVI (both P < 0.01). On multivariable analyses, narrow RM & positive MVI had the highest hazard ratio with reduced OS and RFS (HR 2.96, 95% CI 2.11–4.17, and HR 3.15, 95% CI, 2.09–4.67, respectively). Concomitant having narrow RM and positive MVI increases the risks of postoperative death and recurrence by about 2-fold in patients with solitary HCC. [ABSTRACT FROM AUTHOR]

Background: Hepatitis B virus (HBV) infection is the leading cause of hepatocellular carcinoma (HCC) worldwide. The aim of the study was to identify the incidence and predictive factors of actual 10-year survival following liver resection of HBV-related HCC.Methods: A Chinese multicenter database of patients undergoing curative hepatectomy of HBV-related HCC was reviewed. Patients who survived ≥ 10 years and patients who died < 10 years after surgery were compared and analyzed. Univariable and multivariable regression analyses were performed to identify predictive factors associated with 10-year survival.Results: Among all enrolled 1016 patients, the actuarial 10-year survival rate was 24.1%, while the actual 10-year survival rate was 16.6%. There were 169 patients who survived at least 10 years after surgery and 688 who died within 10 years from surgery. These patients constituted the study population of this study. Multivariable regression analysis revealed that cirrhosis, preoperative HBV viral load > 104 copies/mL, maximum tumor size > 5 cm, multiple tumors, macroscopic and microscopic vascular invasion, postoperative HBV reactivation, and early recurrence (< 2 years after surgery) were independent risk factors associated with actual 10-year survival, while postoperative antiviral therapy, regular recurrence surveillance, and curative treatments for initial recurrence were independent protective factors.Conclusions: The actual 10-year survival after curative resection of HBV-related HCC was calculated to be 16.6%. Postoperative antiviral therapy and regular recurrence surveillance were independent protective factors associated with actual 10-year survival after liver resection of HBV-related HCC.

Abstract Background Serum prealbumin is a sensitive and stable marker for nutritional status and liver function. Whether preoperative prealbumin level is associated with long-term prognosis in patients undergoing liver resection for hepatocellular carcinoma (HCC) is unclear. Methods Patients who underwent liver resection for HCC between 2001 and 2014 at six institutions were enrolled. These patients were divided into the low and normal prealbumin groups using a cut-off value of 170 mg/L for preoperative prealbumin level. The overall survival (OS) and recurrence-free survival (RFS) were compared between them. Results In 1483 patients, 437 (29%) had a low prealbumin level. The 3- and 5-year OS and RFS rates of patients in the low-prealbumin group were 57 and 31%, and 40 and 20%, respectively, which were significantly poorer than those in the normal-prealbumin group (76 and 43%, and 56 and 28%, respectively, both p < 0.001). Multivariable Cox-regression analyses revealed that preoperative prealbumin level was an independent predictor of OS (HR, 1.45, 95% CI: 1.24–1.70, p <0.001) and RFS (HR, 1.28, 95% CI: 1.10–1.48, p <0.001). Conclusions Preoperative prealbumin level could be used in predicting long-term prognosis for patients undergoing liver resection for HCC. [ABSTRACT FROM AUTHOR]

B Introduction: b The long-term prognosis after liver resection for multinodular (>= 3 nodules) hepatocellular carcinoma (HCC) is generally considered to be unfavorable. B Method: b From a multicenter database, consecutive patients who underwent curative-intent liver resection for HCC with 2 tumor nodules and without macrovascular invasion were retrospectively reviewed. B Conclusion: b Liver resection was safe and feasible in patients having HCC with 2 tumor nodules, with acceptable perioperative and long-term outcomes. [Extracted from the article]
