A modified TNM-7 staging system to better predict the survival in patients with hepatocellular carcinoma after hepatectomy

Prognostic value of nutritional and inflammatory markers in patients with hepatocellular carcinoma who receive immune checkpoint inhibitors

The emergence of immune checkpoint inhibitors (ICIs) has provided a new treatment option for patients with hepatocellular carcinoma (HCC). However, further evaluation is needed for determining biomarkers for the use of ICIs. The present study evaluated the prognostic value of certain nutritional and inflammatory markers in patients with HCC who received ICIs. In the present study, the clinical data of 151 patients with HCC who received ICIs at Harbin Medical University Cancer Hospital from January 2019 to December 2021 were collected. The blood parameters of all patients before treatment were collected to evaluate certain nutritional and inflammatory markers, including the prognostic nutrition index (PNI), nutritional risk index (NRI), geriatric NRI (GNRI), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI) and advanced lung cancer inflammation index (ALI). Patients were grouped using the cut-off value calculated using receiver operating characteristic (ROC) curves, and the relationship between these biomarkers and prognosis was evaluated through survival analysis. Furthermore, the prognostic value of these biomarkers was assessed through multivariate Cox regression analysis and construction of nomograms. Finally, time-ROC curves were plotted to compare the differences in predicting prognosis between the biomarkers. In the preliminary survival analysis, all inflammatory and nutritional markers included in the present study were significantly associated with the prognosis of HCC in patients who received ICIs. Similar results were obtained in a subgroup analysis of patients with different Barcelona Clinic Liver Cancer (BCLC) stages. Multivariate Cox regression analysis demonstrated that GNRI, PNI, BCLC stage and Tumor-Node-Metastasis (TNM) stage were significantly associated with progression-free survival (PFS), whereas GNRI, BCLC stage and TNM stage were also significantly associated with overall survival (OS). Furthermore, the time-ROC curves indicated that nutritional indicators had a higher prognostic value in all indexes, especially GNRI. The C-index (95% confidence interval) of the nomograms for predicting the survival probability of patients who received ICIs were 0.801 (0.746-0.877) and 0.823 (0.761-0.898) for PFS and overall OS, respectively, which also showed high accuracy. In conclusion, the present study demonstrated that PNI, GNRI, NRI, SII, SIRI and ALI were all related to the efficacy of ICIs in HCC and could serve as non-invasive biomarkers for ICI treatment effectiveness. Moreover, compared with inflammatory markers, nutritional markers had greater predictive ability, with GNRI being the biomarker with the best prognostic value.

Impact of tumor size on hepatectomy outcomes in hepatocellular carcinoma: a nationwide propensity score matching analysis

Purpose

The aim of this study was to compare surgical outcomes after liver resection for hepatocellular carcinoma (HCC) according to tumor size using a large, nationwide cancer registry-based cohort and propensity score matching.

Methods

From 2008 to 2015, a total of 12,139 patients were diagnosed with liver cancer and registered in the Korean Primary Liver Cancer Registry. Patients without distant metastasis who underwent hepatectomy as a primary treatment were selected. We performed 1:1 propensity score matching between the small (<5 cm), large (≥5 cm and <10 cm), and huge (≥10 cm) groups.

Results

Overall, 265 patients in the small and large groups were compared, and 64 patients each in the large and huge groups were compared. The overall and progression-free survival rates were significantly lower in the large group than in the small group (P < 0.001 and P < 0.001, respectively). Overall survival tended to be poorer in the huge group than in the large group (P = 0.051). The progression-free survival rate was significantly lower in the huge group than in the large group (P = 0.002).

Conclusion

Although primary liver resection can be considered even in patients with huge HCC, greater caution with careful screening for recurrence is needed.

Systematic review and meta-analysis of validated prognostic models for resected hepatocellular carcinoma patients

BACKGROUND

Many prognostic models for Hepatocellular Carcinoma (HCC) have been developed to inform patients and doctors about individual prognosis. Previous reviews of these models were qualitative and did not assess performance at external validation. We assessed the performance of prognostic models for HCC and set a benchmark for biomarker studies.

METHODS

All externally validated models predicting survival for patients with resected HCC were systematically reviewed. After selection, we extracted descriptive statistics and aggregated c-indices using meta-analysis.

RESULTS

Thirty-eight validated prognostic models were included. Models used on average 7 (IQR:4-9) prognostic factors. Tumor size, tumor number, and vascular invasion were almost always included. Alpha-fetoprotein (AFP) was commonly incorporated since 2007. Recently, the more subjective items ascites and encephalopathy have been dropped. Eight established models performed poor to moderate at external validation, with a pooled C-index below 0.7; including the Barcelona Clinic Liver Cancer (BCLC) system, the American Joint Committee on Cancer (AJCC) 7th edition, the Cancer of the Liver Italian (CLIP) Program, and the Japan Integrated Staging (JIS) score. Out of 24 prognostic models predicting OS, only 6 (25%) had good performance at external validation with pooled C-indices above 0.7; the Li-post (0.77), Li-OS (0.74), Yang-pre (0.74), Yang-post (0.76), Shanghai-score (0.70), and Wang-nomogram (0.71). Models improved over time, but overall performance and study quality remained low.

CONCLUSIONS

Six validated prognostic models demonstrated good performance for predicting survival after resection of HCC. These models can guide patients and doctors and are a benchmark for future models incorporating novel biomarkers.

A Prognostic Scoring System for Predicting Overall Survival of Patients with the TNM 8th Edition Stage I and II Hepatocellular Carcinoma After Surgery: A Population-Based Study

Purpose

Postoperative prognosis prediction models for patients with stage Ⅰ and Ⅱ hepatocellular carcinoma (HCC) according to the 8th edition of the Tumor-Node-Metastasis staging system after surgery are rare. This study aimed to build a prognostic score to predict survival outcomes and stratify these patients into different prognostic strata.

Patients and Methods

We developed a web-based nomogram that incorporated four selected risk factors based on the multivariate Cox regression, using a training set (n=3567) from the Surveillance, Epidemiology, and End Results (SEER) database. It was validated with an independent internal set from the SEER database (n=1783) and an external validation set of 516 Chinese patients. The predictive performance and discrimination ability of our model were further evaluated and compared with those of the conventional HCC staging systems.

Results

Our nomogram consistently outperformed the conventional staging systems in the training, internal validation set, and external validation set. We quantified the nomogram model into a numerical SNIG (an abbreviation of the incorporated variables – size, number, MVI, and grade) score by summing the points assigned to each incorporated variable, leading to the optimal cut-off values of 6 and 10, which could stratify patients into 3 categories (SNIG score <6, 6–10, ≥10). This yielded significantly different median overall survivals (interquartile ranges) of 42.0 (20.0–72.0) and 37.0 (17.0–67.0); 28.0 (12.0–60.0) and 42.0 (21.75–82.0); 40.0 (18.0–70.0) and 29.0 (11.5–61.0) months for the 3 categories in the entire SEER and external validation sets, respectively.

Conclusion

We developed a web-based SNIG model to graphically and numerically predict the overall survival of stage Ⅰ and Ⅱ HCC. This scoring system may shed light on risk stratification for these patients in clinical practice and clinical trials.

CHIC Risk Stratification System for Predicting the Survival of Children With Hepatoblastoma: Data From Children With Hepatoblastoma in China

Objective

The aim of this study was to compare the accuracy of the Children’s Oncology Group (COG) risk stratification system to the Children’s Hepatic tumor International Collaboration (CHIC) risk stratification system for predicting the prognosis of Chinese children with hepatoblastoma (HB).

Methods

Clinicopathological data of 86 patients diagnosed with HB between January 2014 and December 2017 were retrieved. The study endpoints were the 1- and 3-year overall survival (OS) and disease-free survival (DFS) were analyzed to evaluate the predictive value.

Results

The 1-, 3-year OS and DFS of the 86 patients were 86.0%, 76.3%, and 74.4%, 54.0%, respectively. Univariate analyses revealed that age at diagnosis had a significant role in prognosis for both OS and DFS, along with PRETEXT staging and metastasis at diagnosis. Multivariate analysis showed that metastasis at diagnosis (HR 3.628, 95% CI 1.404-9.378, P=0.008), PRETEXT staging system (HR 2.176, 95% CI 1.230-3.849, P=0.008) and age at diagnosis (HR 2.268, 95% CI 1.033-4.982, P=0.041) were independent factors for OS. For DFS, the independent factors were the PRETEXT staging system (HR 2.241, 95% CI 1.533-3.277, P<0.001) and age at diagnosis (HR 1.792, 95% CI 1.018-3.154, P=0.043). Both COG and CHIC risk stratification systems could effectively predict the prognosis of children with HB for OS. For DFS, the CHIC risk stratification system was more effective. In addition, the CHIC risk stratification system had a higher c-index (OS 0.743, DFS 0.730), compared to the COG risk stratification system (OS 0.726, DFS 0.594).

Conclusion

Age at diagnosis played a significant role in prognosis. Compared to the COG risk stratification system, the CHIC risk stratification system was superior in predicting the survival of Chinese children with HB.

[Early stage liver cancer : Hepatocellular carcinoma]

Hepatocellular carcinoma (HCC) ranks among the most common primary cancers of the liver. The major risk factor for the formation of HCC is liver cirrhosis. The grade of cirrhosis as well as the extent of the tumor itself, can play an important role in the treatment options and patient prognosis. An operation aimed at an R0 resection is the treatment of choice for patients in an early stage of the disease and is associated with favorable long-term and recurrence-free survival. Liver transplantation offers an even better long-term survival rate after 5 years for selected patients with HCC meeting the Milan criteria as the underlying cirrhosis, the major risk factor for HCC recurrence, is simultaneously treated. Local tumor ablation is the least invasive curative surgical treatment, however, it is associated with an increased local recurrence rate; therefore, the early detection of tumors is of essential importance. As tumor-associated symptoms tend to arise only in advanced tumor stages, it is indispensable to identify patients with typical risk factors and to provide closely monitored screening examinations.

The 7th/8th American Joint Committee on Cancer and the Modified Union for International Cancer Control Staging System for Hepatocellular Carcinoma

PURPOSE

Although many staging systems have been proposed for hepatocellular carcinoma (HCC), there is no globally accepted system due to the extreme heterogeneity of the disease. We aimed to compare the results of the 7th/8th American Joint Committee on Cancer (AJCC) and the modified Union for International Cancer Control (mUICC) staging systems in patients with HCC.

MATERIALS AND METHODS

We collected data from 792 patients who underwent hepatic resection at our center. The Kaplan-Meier method was used to determine disease-free survival and overall survival. To evaluate homogeneity, '-2 log likelihood' was calculated using Cox proportional hazards regression. To measure discriminatory ability, the linear trend chi method and the Cochran-Armitage test for trend were used. The ability to accurately predict survival was verified by cross-validation analysis.

RESULTS

Kaplan-Meier curves for disease-free survival and overall survival showed mUICC to be superior to the 7th/8th AJCC. The homogeneity test indicated that mUICC was the best for both disease-free survival and overall survival. In the discriminatory ability test, the chi-square value of mUICC was the best for disease-free survival, while the 7th AJCC had the best value for overall survival. In the cross-validation analysis, all three staging systems had significant predictive power.

CONCLUSION

mUICC seemed to be superior to the 7th/8th AJCC after analyzing the data of our surgical patients, although the geographic heterogeneity of HCC might result in differences between the staging systems. We believe that, while the three staging systems allow for the clear stratification of patients into prognostic groups, mUICC may be more appropriate in HCC.

Survival analysis after liver resection for hepatocellular carcinoma: A consecutive cohort of 1002 patients

BACKGROUND AND AIM

The improvements in surgical technique and perioperative management in the recent decades may warrant revisit for survival outcomes and prognostic factors after liver resection for hepatocellular carcinoma (HCC). This study aimed to analyze the survival outcomes after liver resection for HCC for a consecutive cohort of 1002 patients.

METHODS

This study was performed by analyzing the clinicopathological and follow-up data of 1002 consecutive patients who underwent liver resection for HCC from April 2001 to December 2013. Prognostic factors were investigated by univariate and multivariate analysis, using the Cox's proportional hazards model.

RESULTS

The overall incidence of postoperative complications was 16.1% (n = 161), with an in-hospital mortality rate of 0.3% (n = 3). The rates of 1-, 3-, and 5-year overall survival were 91.9%, 78.9%, and 69.5%, while the rates of 1-, 3-, and 5-year recurrence-free survival were 71.7%, 51.7%, and 43.7%, respectively. Multivariate analysis showed that patient age, platelet count, intraoperative estimated blood loss (EBL), tumor number, Edmond-Steiner grade, microvascular invasion, major vessel invasion, and intrahepatic metastasis were independent significant prognostic factors affecting the overall survival. Platelet count, intraoperative EBL, maximal tumor size, major vessel invasion, capsule formation, intrahepatic metastasis, cirrhosis, and the pathological stage were independent prognostic factors for recurrence-free survival.

CONCLUSIONS

Survival of patients with HCC after resection should be stratified by various perioperative clinicopathological factors. Platelet count and intraoperative EBL could be considered as one of the powerful predictors of the prognosis and recurrence of HCC in such patients.

2014 KLCSG-NCC Korea Practice Guideline for the Management of Hepatocellular Carcinoma

The guideline for the management of hepatocellular carcinoma (HCC) was first developed in 2003 and revised in 2009 by the Korean Liver Cancer Study Group and the National Cancer Center, Korea. Since then, many studies on HCC have been carried out in Korea and other countries. In particular, a substantial body of knowledge has been accumulated on diagnosis, staging, and treatment specific to Asian characteristics, especially Koreans, prompting the proposal of new strategies. Accordingly, the new guideline presented herein was developed on the basis of recent evidence and expert opinions. The primary targets of this guideline are patients with suspicious or newly diagnosed HCC. This guideline provides recommendations for the initial treatment of patients with newly diagnosed HCC.

Staging systems for hepatocellular carcinoma: Current status and future perspectives

Hepatocellular carcinoma (HCC) is a major health concern worldwide and the third cause of cancer-related death. Despite advances in treatment as well as careful surveillance programs, the mortality rates in most countries are very high. In contrast to other cancers, the prognosis and treatment of HCC depend on the tumor burden in addition to patient’s underlying liver disease and liver functional reserve. Moreover, there is considerable geographic and institutional variation in both risk factors attributable to the underlying liver diseases and the management of HCC. Therefore, although many staging and/or scoring systems have been proposed, there is currently no globally accepted system for HCC due to the extreme heterogeneity of the disease. The aim of this review is to focus on currently available staging systems as well as those newly reported in the literatures since 2012. Moreover, we describe problems with currently available staging systems and attempts to modify and/or add variables to existing staging systems.

Long-term survival in patients with T2 hepatocellular carcinoma after primary curative resection can be further stratified by tumor size

Insufficient data are available regarding the validation of long-term survival in patients with T2 (solitary tumor with microvascular invasion [MVI] or multiple tumors, none >5 cm) hepatocellular carcinoma (HCC) after primary hepatectomy. We aim to evaluate the survival and relevant risk factors for T2 HCC patients. Between 2001 and 2007, 312 T2 HCC patients who underwent primary hepatectomy were included. Survival was estimated using the Kaplan-Meier method and compared using Cox proportional hazard model with adjusted independent prognostic factors. The 1, 3, and 5-year overall survival rates of patients with MVI were 85.7%, 68.7%, and 64.8%, respectively; these were inferior to the rates in patients without MVI, which were 93.0%, 89.3%, and 73.7%, respectively (P = 0.037). Within the with-MVI group, the survival rate of patients with tumor sizes ≥ 5 cm was inferior to that of patients with tumors <5 cm (overall, P = 0.01; recurrence-free, P < 0.0001). For patients with the largest tumors in the <5-cm group, those without MVI tended to have a higher probability of recurrence for 2 years after resection (P = 0.088) but a similar overall survival rate relative to those with MVI (P = 0.31). The crude metastasis-free survival was higher in the without-MVI group than in the with-MVI group (P = 0.012). The T2 HCC category comprised heterogeneous patients with differences in survival rates. Extrahepatic recurrence occurred more frequently in patients with MVI than in those without MVI. These results provide evidence for an updated definition of T2 HCC.

Outcome following major hepatic resection in the elderly patients

Recent advances in operative techniques, anaesthesiologic management and intensive care have greatly reduced morbidity and mortality of major hepatectomy allowing a progressive broadening of its indications by including patients with chronic liver disorders as well as elderly subjects. It is apparent that with the aging population, more elderly patients are being referred for surgery. Selecting appropriate candidates for surgical resection is therefore crucial to maximize the benefit derived from surgery. Nevertheless, it is not clear whether advanced age itself increases surgical risk or additional age-independent variables are associated with higher operative morbidity. Regardless of the indications for surgery and the extent of planned liver resections, this population is more likely to suffer from relevant disorders. Previous studies on the safety of major liver resections in the elderly patients cite morbidity and mortality rates of approximately 30-40% and 4-5% respectively. In addition, hepatic resections for hepatocellular carcinoma or colorectal liver metastases have been reported as safe in the elderly as in the younger population. Nevertheless, a small number of investigations studied the outcome of major hepatectomy in the population over 70 years of age. The aim of our study was to evaluate overall experience with liver resections in the elderly population by comparing the early as well as the long-term outcome of the procedure in 70 years and older versus the less than 70 age group and to identify whether the age of patients alone is associated with increased rate and severity of postoperative complications.

Number of nodules, Child-Pugh status, margin positivity, and microvascular invasion, but not tumor size, are prognostic factors of survival after liver resection for multifocal hepatocellular carcinoma

BACKGROUND

Presently, the role of liver resection (LR) for multifocal hepatocellular carcinoma (HCC) remains controversial. However, in many regions worldwide, LR remains the only treatment modality available to such patients which offers the possibility of long-term cure. The aim of this study is to determine the outcomes and prognostic factors of patients with multifocal HCC after LR.

METHODS

This is a retrospective analysis of 110 patients who underwent potentially curative LR for pathologically proven multifocal HCC between 2000 and 2011.

RESULTS

The median age was 64 (range, 18-84) years, and there were 88 males (80.0 %). Sixty-one patients underwent a major hepatectomy, and the overall postoperative mortality was 1.8 %. Sixty-eight patients had liver cirrhosis, of which, 58 were child's A and 10 were child's B. The 1- and 5-year overall survival (OS) was 82 and 44 %, respectively. The corresponding 1- and 5-year recurrence-free survival (RFS) was 57 and 19 %, respectively. Multivariate analysis demonstrated that the number of nodules (>3) and presence of microvascular invasion were associated with RFS. Number of nodules (>3), margin positivity, Child-Pugh status, and presence of microvascular invasion were independent prognostic factors of OS.

CONCLUSIONS

LR followed by treatment of recurrences may result in reasonable long-term survival and should be considered in a selected group of patients with multifocal HCC. Number of nodules (>3), margin positivity, Child-Pugh status, and presence of microvascular invasion, but not tumor size, were independent negative predictors of OS. These findings have potential implications on the AJCC staging for multifocal HCC.

Vasohibin 2 decreases the cisplatin sensitivity of hepatocarcinoma cell line by downregulating p53

Hepatocellular carcinoma (HCC) is a prevalent problem worldwide. Chemotherapy, especially cisplatin (CDDP)-based systemic chemotherapy, is the best option for advanced liver cancer. However, CDDP resistance is becoming common and hindering the clinical application of CDDP. Meanwhile, no consensus has been reached regarding the chemotherapeutic use of vasohibin 2 (VASH2), which promotes the angiogenesis and proliferation of cancer cells. In this work, a tissue microarray was used to observe VASH2 and its possible role in cancer treatment. Results showed that VASH2 was highly expressed in HCC tissues and was significantly correlated with cancer differentiation. To further investigate the efficacy and mechanism of the combination of VASH2 with anti-cancer drugs in liver cancer cells, we stably built VASH2 overexpression and knockdown cell lines. We found that VASH2 can influence the CDDP sensitivity and that the cell overexpression of VASH2 had a higher cell viability and lower apoptosis rate after CDDP exposure. We also observed that VASH2 overexpression downregulated wild-type p53, as well as suppressed the expression of the pro-apoptotic protein BCL2-associated X protein (Bax) and cleaved caspase-3 (CC-3) after treatment by CDDP. Conversely, the knockdown of VASH2 significantly inhibited these effects. In an in vivo chemosensitivity study, nude mice were subcutaneously injected with tumor cells and received CDDP treatment through intraperitoneal administration every 3 days. We found that VASH2 knockdown markedly limited the tumor growth and enhanced the CDDP toxicity and apoptosis of tumor cells. Western blot analysis revealed that tumor cells with downregulated VASH2 had a higher expression of wild-type p53, Bax, and CC-3 than control cells. Overall, our results indicated the novel roles of VASH2 in the chemoresistance of hepatocarcinoma cells to CDDP and suggested that VASH2 may be a promising anticancer target.
