Pathological predictive factors for late recurrence of hepatocellular carcinoma in chronic liver disease.

ABSTRACT:

Background & aims

Late recurrence of hepatocellular carcinoma (HCC) is regarded as de novo HCC from chronic hepatitis. This study investigated clinicopathological and molecular factors to develop a nomogram for predicting late HCC recurrence (>2 years after curative resection).

Methods

The training and validation cohorts included HCC patients with a major aetiology of hepatitis B who underwent curative resection. Clinicopathological features including lobular and porto-periportal inflammatory activity, fibrosis and liver cell change were evaluated. Proteins encoded by genes related to late recurrence were identified using a reverse phase protein array of 95 non-tumourous liver tissues. Immunoexpression of phosphorylated signal transducer and activator of transcription 3 (pSTAT3), plasminogen activator inhibitor-1, phosphorylated extracellular signal-regulated kinase 1/2 (pERK1/2) and spleen tyrosine kinase (SYK) was measured.

Results

Late recurrence occurred in 74/402 (18%) and 47/243 (19%) in the training and validation cohorts respectively. Cirrhosis, moderate/severe lobular inflammatory activity, and expression of pSTAT3, pERK1/2, and SYK proteins correlated to the gene signature of hepatocyte injury and regeneration were independently associated with late recurrence, with odds ratios (95% confidence intervals) of 2.0 (1.2-3.3), 21.1 (4.3-102.7) and 6.0 (2.1-17.7) respectively (P < .05 for all). A nomogram based on these variables (histological parameters and immunohistochemical marker combinations) showed high reliability in both the training and validation cohorts (Harrell's C index: 0.701 and 0.716; 95% confidence intervals: 0.64-0.76 and 0.64-0.79 respectively).

Conclusions

The combination of pSTAT3, pERK1/2 and SYK immunoexpression with high lobular inflammatory activity and cirrhosis (fibrosis) predicts late HCC recurrence.

Project description:ImportanceLate recurrence (more than 2 years) after liver resection for hepatocellular carcinoma (HCC) is generally considered as a multicentric tumor or a de novo cancer.ObjectiveTo investigate the risk factors, patterns, and outcomes of late recurrence after curative liver resection for HCC.Design, setting, and participantsThis study was a multicenter retrospective analysis of patients who underwent curative liver resection for HCC at 6 hospitals in China from January 2001 to December 2015. Among 734 patients who were alive and free of recurrence at 2 years after resection, 303 patients developed late recurrence. Data were analyzed from June 2017 to February 2018.InterventionsLiver resection for HCC.Main outcomes and measuresRisk factors of late recurrence as well as patterns, treatments, and long-term outcomes of patients with late recurrence. Univariate and multivariate Cox regression analyses were performed to identify independent risk factors of late recurrence.ResultsOf the included 734 patients, 652 (88.8%) were male, and the mean (SD) age was 51.0 (10.3) years. At a median (interquartile range) follow-up of 78.0 (52.8-112.5) months, 303 patients (41.3%) developed late recurrence. Multivariate analysis revealed that male sex, cirrhosis, multiple tumors, satellite nodules, tumor size greater than 5 cm, and macroscopic and microscopic vascular invasion were independent risk factors of late recurrence. Of the 303 patients with late recurrence, 273 (90.1%) had only intrahepatic recurrence, 30 (9.9%) had both intrahepatic and extrahepatic recurrence, and none had only extrahepatic recurrence. Potentially curative treatments were given to 165 of 303 patients (54.5%) with late recurrence, which included reresection, transplant, and local ablation. Multivariate Cox regression analysis showed that regular surveillance for postoperative recurrence (hazard ratio [HR], 0.470; 95% CI, 0.310-0.713; P = .001), cirrhosis (HR, 1.381; 95% CI, 1.049-1.854; P = .02), portal hypertension (HR, 2.424; 95% CI, 1.644-3.574; P < .001), Child-Pugh grade of B or C (HR, 1.376; 95% CI, 1.153-1.674; P < .001), Barcelona Clinic Liver Cancer stage B (HR, 1.304; 95% CI, 1.007-1.708; P = .04) and stage C (HR, 2.037; 95% CI, 1.583-2.842; P < .001), and potentially curative treatment (HR, 0.443; 95% CI, 0.297-0.661; P < .001) were independent predictors of overall survival for patients with late recurrence.Conclusions and relevanceLate recurrence after HCC resection was associated with sex, cirrhosis, and several aggressive tumor characteristics of the initial HCC. The patterns of late recurrence suggested surveillance for recurrence after 2 years of surgery should be targeted to the liver. Postoperative surveillance improved the chance of potentially curative treatments, with improved survival outcomes in patients with late recurrence.

Project description:BackgroundAn individual prognostic model that includes inflammation caused by the delayed recovery of liver function after surgery for the early recurrence of hepatocellular carcinoma (HCC) following liver transplantation (LT) has not been well determined. Our aim was to develop a nomogram model for predicting individual survival and early recurrence following LT for patients.MethodsRetrospective data, including clinical pathology and follow-up data, on HCC patients were collected between October 2016 and October 2019 at Huashan Hospital Affiliated to Fudan University. A nomogram estimating recurrence post-transplantation was constructed using multivariate Cox regression analysis.ResultsA total of 210 patients were included in the present study. The multivariate estimators of recurrence consisted of age, maximum tumor diameter, tumor thrombus, microvascular invasion (MVI), alanine aminotransferase and alpha-fetoprotein on postoperative day 7. Nomogram of recurrence-free survival was developed. The calibration and discrimination of the novel model were assessed with the calibration curves and concordance index (C-index). Its reliability and advantages were evaluated by comparing it with the conventional American Joint Committee on Cancer (AJCC) 8th edition staging system using integrated discrimination improvement (IDI) and net reclassification improvement (NRI). In comparison to the AJCC 8th edition staging system, the C-index (development set: 0.796 vs. 0.643, validation set: 0.741 vs. 0.563), the area under the receiver operating characteristic curve (AUC) of the validation set (1-year AUC: 0.732 vs. 0.586, 2-year AUC: 0.705 vs. 0.504), the development set (1-year AUC: 0.799 vs. 0.551, 2-year AUC: 0.801 vs. 0.512), and this model's calibration plots all showed improved performance. In addition, NRI and IDI verified that the nomogram is an accurate prognostic tool. Subsequently, a web calculator was generated to assess the risk of tumor recurrence post-LT.ConclusionsThe nomogram, based on clinical and pathological factors, showed good accuracy in estimating prognostic recurrence and can be used to guide individual patient follow-up and treatment.

Project description:BackgroundSurvival after liver resection of hepatocellular carcinoma (HCC) remains poor because of a high incidence of recurrence. We sought to investigate risk factors, patterns, and long-term prognosis among patients with early and late recurrence after liver resection for hepatitis B virus (HBV)-associated HCC.MethodsData of consecutive patients undergoing curative resection for HBV-associated HCC were analyzed. According to the time to recurrence after surgery, recurrence was divided into early (≤2 years) and late recurrence (>2 years). Characteristics, patterns of initial recurrence, and postrecurrence survival (PRS) were compared between patients with early and late recurrence. Risk factors of early and late recurrence and predictors of PRS were identified by univariable and multivariable Cox regression analyses.ResultsAmong 894 patients, 322 (36.0%) and 282 (31.5%) developed early and late recurrence, respectively. On multivariable analyses, preoperative HBV-DNA >104 copies/mL was associated with both early and late recurrence, whereas postoperative no/irregular antiviral therapy was associated with late recurrence. Compared with patients with late recurrence, patients with early recurrence had a lower proportion of intrahepatic-only recurrence (72.0% vs. 91.1%, p < .001), as well as a lower chance of receiving potentially curative treatments for recurrence (33.9% vs. 50.7%, p < .001) and a worse median PRS (19.1 vs. 37.5 months, p < .001). Multivariable analysis demonstrated that early recurrence was independently associated with worse PRS (hazard ratio, 1.361; 95% confidence interval, 1.094-1.692; p = .006).ConclusionAlthough risk factors associated with early recurrence and late recurrence were different, a high preoperative HBV-DNA load was an independent hepatitis-related risk for both early and late recurrence. Early recurrence was associated with worse postrecurrence survival among patients with recurrence.Implications for practiceLiver resection is the main curative treatment for hepatocellular carcinoma (HCC), but postoperative survival remains poor because of high recurrence rates. This study investigated the risk factors and patterns of early and late recurrence and found that a high preoperative hepatitis B virus (HBV) DNA load was an independent hepatitis-related risk factor for both. Early recurrence was also independently associated with worse postrecurrence survival. These data may provide insights into different biological origin and behavior of early versus late recurrence after resection for HBV-associated HCC, which could be helpful to make individualized treatment decision for recurrent HCC, as well as strategies for surveillance recurrence after resection.
