Systematic Review of Studies Assessing the Health-Related Quality of Life of Hepatocellular Carcinoma Patients from 2009 to 2018

Health-related quality of life in patients with unresectable hepatocellular carcinoma treated with SIRT and nivolumab: a sub-analysis of the NASIR-HCC trial

BACKGROUND

The health-related quality of life (HRQoL) impact of therapies for hepatocellular carcinoma (HCC) influences decision-making and treatment outcomes. The present study reports HRQoL results from NASIR-HCC, a single-arm study of selective internal radiation therapy (SIRT) with Y90 resin microspheres followed by nivolumab for unresectable HCC.

METHODOLOGY

Participants completed the EQ-5D-3 L, EQ-VAS, and FACT-Hep at baseline and on the first day of each nivolumab cycle. Linear mixed-effect models were used to calculate changes in outcomes in participants with the baseline and ≥ 1 follow-up measurement. Changes were assessed for clinical meaningfulness versus published minimally important differences.

RESULTS

Thirty-two patients from NASIR-HCC were included. Completion rates exceeded 70% at 62% of time points. Across EQ-5D-3 L domains, minimal changes were reported. Most patients had no problems at almost all time points. Mean index values were 0.864 at baseline and 0.763 in cycle 8, but this difference was not clinically meaningful. The small EQ-VAS increase, from 74.8 at baseline to 75.9 in cycle 8, was also not clinically meaningful. The various FACT scales remained stable, although transient but not clinically meaningful declines occurred for some scales. The median time to deterioration was 5.5 months for the FACT-Hep score.

CONCLUSIONS

Combining SIRT with nivolumab did not compromise HRQoL in patients with unresectable HCC. Study results were limited by the small number of patients but, combined with the previously reported clinical outcomes, suggested that the treatment combination deserves further consideration in this difficult-to-treat population.

Psychosocial factors associated with quality of life in cancer patients undergoing treatment: an umbrella review

BACKGROUND

Cancer treatment greatly impacts physical and psychological functioning of cancer patients, negatively affecting their quality of life (QoL). This Umbrella Review (UR) aims to systematically summarize psychological and social factors positively or negatively associated with QoL in cancer patients undergoing treatment.

METHOD

Four scientific databases (PubMed, Embase, Scopus, and PsycInfo) were searched to identify systematic reviews between 2012 and 2023 analyzing the relationship between QoL and psychosocial factors in cancer patients in treatment. The UR was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Joanna Briggs Institute (JBI) review guidelines. The methodological quality of the included studies was evaluated using Assessment of Multiple Systematic Reviews 2 (AMSTAR2).

RESULTS

Eighteen systematic reviews were included. The major psychological factors influencing QoL are depression, coping strategies, anxiety, and distress. Results also demonstrate the significant impact of social factors on QoL: perceived social support has a positive influence on QoL of cancer patients, while lowered social support, impaired social functioning, interactions, and role limitations worsen their QoL and overall well-being.

CONCLUSION

This UR provides a comprehensive overview of the psychosocial factors impacting QoL of cancer patients and serves as a prominent base for developing questionnaires and policies aimed at measuring QoL in cancer patients undergoing treatment. Moreover, the findings of the study can guide future research or the development of personalized clinical interventions aimed at improving QoL for this cancer population group.

Symptom Cluster Trajectories Among Patients With Hepatocellular Carcinoma After Partial Hepatectomy: A Longitudinal Study

AIMS

To investigate types of symptom clusters in patients with hepatocellular carcinoma after partial hepatectomy and explore symptom cluster trajectories over time.

DESIGN

A longitudinal observational study was conducted.

METHODS

Symptoms of patients with hepatocellular carcinoma were assessed on the second day, seventh day, third week, fourth week and twelfth week post-operation using the MD Anderson Symptom Assessment Inventory and the Symptom Module for Primary Liver Cancer. Symptom clusters were extracted using exploratory factor analysis, and symptom cluster trajectories were analysed using a latent class growth model.

RESULTS

Two hundred and thirty patients with hepatocellular carcinoma completed the five-point investigation after partial hepatectomy. Three symptom clusters were identified: general somatic, psychological and liver impairment. Each symptom cluster was further categorised into three groups: severe, moderate and low. The severity of the three symptom clusters and subgroups decreased over time.

CONCLUSION

Three symptom clusters were identified in patients who underwent partial hepatectomy for hepatocellular carcinoma, and symptom cluster trajectories decreased over time during the 12-week postoperative period. These findings will assist healthcare professionals in providing prompt symptom management and improve patient quality of life.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

Healthcare professionals should evaluate symptom clusters and their trajectories in patients with hepatocellular carcinoma after partial hepatectomy.

REPORTING METHOD

This report was prepared in accordance with the Guidelines for Reporting Cohort Research.

PATIENT OR PUBLIC CONTRIBUTION

Hepatobiliary surgery nurses worked closely with the research team to ensure the questionnaires were fully assessed before being sent to patients. The active participation of patients provided valuable information for the study.

Dynamics trajectory of patient-reported quality of life and its associated risk factors among hepatocellular carcinoma patients receiving immune checkpoint inhibitors: a prospective cohort study

Objective

We aimed to characterize quality of life (QOL) trajectories among patients with intermediate and advanced hepatocellular carcinoma patients treated with immunotherapy.

Methods

Barcelona Clinic Liver Cancer (BCLC) stage B-C HCC patients receiving immunotherapy at Guangxi Medical University Cancer Hospital were included. Trajectories of QOL, assessed using the Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) questionnaire, were identified through iterative estimations of group-based trajectory models. Associations with trajectory group membership were analyzed using multivariable multinomial logistic regression.

Results

Three trajectory groups were identified (n=156): excellent (35.3%), poor (43.6%), and deteriorating (21.1%) QOL. The deteriorating trajectory group reported a mean QOL score of 124.79 (95% CI, 116.58-133.00), but then declined significantly at month-2 (estimated QOL score 98.67 [95% CI, 84.33-113.00]), and the lowest mean score is reached at month-6 (estimated QOL score 16.58 [95% CI, 0-46.07]). Factors associated with membership to the deteriorating group included no drinking (odds ratio [OR] vs yes [95% CI], 3.70 [1.28-11.11]), no received radiotherapy (OR vs yes [95% CI], 8.33 [1.41-50.00]), diabetes (OR vs no [95% CI], 6.83 [1.57-29.73]), and extrahepatic metastasis (OR vs no [95% CI], 3.08 [1.07-8.87]). Factors associated with membership to the poor group also included body mass index ≤24.0 kg/m2 (OR vs no [95% CI], 4.49 [1.65-12.22]).

Conclusions

This latent-class analysis identified a high-risk cluster of patients with severe, persistent post-immunotherapy QOL deterioration. Screening relevant patient-level characteristics may inform tailored interventions to mitigate the detrimental impact of immunotherapy and preserve QOL.

Associations of tumor-related psychiatric symptoms and healthy behaviors with dynamic quality of life after hepatocellular carcinoma hepatectomy

OBJECTIVE

To assess the independent and combined associations of tumor-related psychiatric symptoms (TRPS) with dynamic health-related quality of life (HRQL) in patients with hepatocellular carcinoma (HCC) after hepatectomy and to identify related patterns of health behaviors.

METHODS

This prospective study included patients with HCC who underwent hepatectomy between September 2021 and May 2022. Independent and combined associations between TRPS and HRQL were identified by generalized linear model and weighted quantile sum model, respectively. Trajectories of HRQL were identified by latent class mixed model.

RESULTS

Among the 205 patients, 174 (84.9%) were male. For the outcome of HRQL at 6 months: Anxiety, depression, fatigue, and sleep disorder were independently associated with a decrease of HRQL (all P < 0.05). A negative combined effect of TRPS was also found (β =  - 5.07, 95% CI, - 10.01 to - 0.13), with depression emerged as the predominant contributor (49%). The health behaviors of body mass index, smoking, drinking, or physical exercise were not significantly modified the associations between combined TRPS and HRQL (all P > 0.05 for interaction). Similar results were also found for the HRQL at baseline and at 1 and 3 months. Three HRQL trajectory groups were identified: recover (44.9%), poor (44.4%), and deteriorating (10.7%). Deteriorating group was associated with higher incidence of TRPS (all P < 0.05).

CONCLUSIONS

TRPS were associated with a decrease of HRQL regardless of healthy behaviors in HCC patients. Therefore, healthy behaviors promotion alone might not substantially increase HRQL associated with TRPS, and other measures tackling TRPS are warranted.

A Phase 3 Study of Pembrolizumab versus Placebo for Previously Treated Patients from Asia with Hepatocellular Carcinoma: Health-Related Quality of Life Analysis from KEYNOTE-394

Introduction

KEYNOTE-394 showed pembrolizumab significantly improved overall survival, progression-free survival, and objective response rate with manageable safety versus placebo for patients from Asia with previously treated advanced hepatocellular carcinoma. We present results on health-related quality of life (HRQoL).

Methods

HRQoL was evaluated using the EORTC Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and EuroQol-5D-3L (EQ-5D-3L) questionnaires. Key HRQoL endpoints were least squares mean (LSM) score changes from baseline to week 12 and time to deterioration (TTD) for EORTC QLQ-C30 global health status (GHS)/QoL. p values were one-sided and nominal without adjustment for multiplicity.

Results

The HRQoL population included patients randomly assigned to pembrolizumab (n = 298) and placebo (n = 152). From baseline to week 12, a greater decline in EORTC QLQ-C30 GHS/QoL score was observed with placebo (LSM, -8.4; 95% CI: -11.7 to -5.1) versus pembrolizumab (-4.0; 95% CI: -6.4 to -1.6; difference vs. placebo: 4.4; 95% CI: 0.5-8.4; nominal p = 0.0142). Similarly, a greater decline in the EQ-5D-3L visual analog scale score was observed with placebo (-6.9; 95% CI: -9.4 to -4.5) versus pembrolizumab (-2.7; 95% CI: -4.5 to -1.0; difference vs. placebo: 4.2; 95% CI: 1.2-7.2; nominal p = 0.0030). TTD in EORTC QLQ-C30 GHS/QoL score was similar between arms (hazard ratio, 0.85; 95% CI: 0.58-1.25; nominal p = 0.1993).

Conclusion

Patients receiving placebo showed a greater decline in HRQoL than those receiving pembrolizumab. Combined with efficacy and safety data from KEYNOTE-394 and the global KEYNOTE-240 and KEYNOTE-224 trials, our data support the clinically meaningful benefit and manageable tolerability of pembrolizumab as second-line therapy for patients with advanced hepatocellular carcinoma.

Influence of transcatheter arterial embolization on symptom distress and fatigue in liver cancer patients

BACKGROUND

Hepatocellular carcinoma (HCC) is a prevalent malignancy, and transcatheter arterial embolization (TAE) has emerged as a pivotal therapeutic modality. However, TAE may induce symptom distress and fatigue, adversely affecting the quality of life of patients.

AIM

To investigate symptom distress, fatigue, and associated factors in HCC patients undergoing TAE.

METHODS

We used a cross-sectional design and purposive sampling to enroll HCC patients who underwent TAE at our institution from January to December 2022. Questionnaires were utilized to collect data on symptom distress and fatigue scores from the first to the third day after TAE.

RESULTS

Our study revealed a significant reduction in fatigue and symptom distress among patients after TAE. Pain, fatigue, insomnia, fever and abdominal distension were the most common symptoms troubling patients during the first 3 d post-TAE. Marital status, presence of family support, physical functional status, age, and symptom distress were identified as predictors of fatigue in patients.

CONCLUSION

Healthcare professionals should educate HCC patients on symptom distress and fatigue, offering personalized relief strategies to lessen their psychological burden.

Predictors of sleep quality components in patients undergoing transarterial chemoembolisation: a cross-sectional study

PURPOSE

Patients undergoing transarterial chemoembolisation experience postembolisation symptoms and interferences affecting sleep quality, which require intervention. The study aimed to identify the predictors of sleep quality components in patients undergoing transarterial chemoembolisation.

METHODS

This study included two groups of participants: 50 patients undergoing transarterial chemoembolisation and 45 nurses caring for them. Data were collected from September to November 2022 using a structured questionnaire, and analysed using descriptive statistics, the t-test, analysis of variance, Spearman's rank correlation, and multiple regression analysis using the SPSS 27.0 program (IBM Corp., Armonk, NY, USA).

RESULTS

The mean sleep quality score was 40.28±14.10. Heat sensation (t=-2.08, p=.043) and fatigue (t=-4.47, p<.001) predicted sleep fragmentation in 38.6% of the patients. Abdominal pain (t=-2.54, p=.014), vomiting (t=-2.21, p=.032), and the expected fatigue by the nurses (t=2.68, p=.014) predicted sleep length in 41.7% of patients. Abdominal pain (t=-2.05, p=.046) explained 42.9% of sleep depth.

CONCLUSION

Based on the predictors of sleep quality components obtained in this study, strategies to improve sleep quality tailored to patients undergoing transarterial chemoembolisation should be developed. This study highlighted the need to bridge the gap between patients' and nurses' expected fatigue and its contribution to sleep fragmentation and sleep length. It also highlighted the importance of noncontact temperature measurement, controlling vomiting, and pain relief for improving sleep length in patients undergoing transarterial chemoembolisation.

Relationship of Hepatocellular Carcinoma Stage and Hepatic Function to Health-Related Quality of Life: A Single Center Analysis

Health-related quality of life (HRQoL) is known to be an important prognostic indicator and clinical endpoint for patients with hepatocellular carcinoma (HCC). However, the correlation of the Barcelona Clinic Liver Cancer (BCLC) stage with HRQoL in HCC has not been previously studied. We examined the relationship between BCLC stage, Child-Pugh (CP) score, and Eastern Cooperative Oncology Group (ECOG) performance status on HRQoL for patients who presented at a multidisciplinary liver cancer clinic. HRQoL was assessed using the Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) questionnaire. Fifty-one patients met our inclusion criteria. The FACT-Hep total and subscales showed no significant association with BCLC stages (p = 0.224). Patients with CP B had significantly more impairment in FACT-Hep than patients with CP A. These data indicate that in patients with HCC, impaired liver function is associated with reduced quality of life, whereas the BCLC stage poorly correlates with quality of life metrics. Impairment of quality of life is common in HCC patients and further studies are warranted to determine the impact of early supportive interventions on HRQoL and survival outcomes.

A Delphi Study of Core Patient-Reported Outcomes for Advanced Renal Cell Carcinoma and Advanced Hepatocellular Carcinoma

OBJECTIVES

There is little research to help health care professionals understand what patient outcomes are considered a priority in advanced liver or kidney cancer. Knowing what is important to patients can help promote person-centered approaches to treatment and disease management. The aim of this study was to identify those patient-reported outcomes (PROs) that patients, carers, and health care professionals consider as "core" when providing care to those with advanced liver or kidney cancer.

DATA SOURCES

A three-round Delphi study was undertaken to ask experts by profession or experience to rank PROs identified from a previous literature review. Fifty-four experts, including people living with advanced liver or kidney cancer (44.4%), family members and caregivers (9.3%), and health care professionals (46.8%), reached consensus on 49 PROs including 12 new items (eg, palpitations, hopefulness, or social isolation). Items with the highest rate of consensus included quality of life, pain, mental health, and capacity to do daily activities.

CONCLUSION

People living with advanced liver or kidney cancer experience complex health care needs. Some important outcomes were not actually captured in practice in this population and were suggested as part of this study. There are discrepancies between the views of health care professionals, patients, and family in what is important, highlighting the need of using measures to facilitate communication.

IMPLICATIONS FOR NURSING PRACTICE

Identification of priority PROs reported here will be key to facilitate more focused patient assessments. The actual use of measures in cancer nursing practice to allow monitoring of PROs must be tested for feasibility and usability.

Natural Language Processing for Automated Classification of Qualitative Data From Interviews of Patients With Cancer

OBJECTIVES

This study sought to explore the use of novel natural language processing (NLP) methods for classifying unstructured, qualitative textual data from interviews of patients with cancer to identify patient-reported symptoms and impacts on quality of life.

METHODS

We tested the ability of 4 NLP models to accurately classify text from interview transcripts as "symptom," "quality of life impact," and "other." Interview data sets from patients with hepatocellular carcinoma (HCC) (n = 25), biliary tract cancer (BTC) (n = 23), and gastric cancer (n = 24) were used. Models were cross-validated with transcript subsets designated for training, validation, and testing. Multiclass classification performance of the 4 models was evaluated at paragraph and sentence level using the HCC testing data set and analyzed by the one-versus-rest technique quantified by the receiver operating characteristic area under the curve (ROC AUC) score.

RESULTS

NLP models accurately classified multiclass text from patient interviews. The Bidirectional Encoder Representations from Transformers model generally outperformed all other models at paragraph and sentence level. The highest predictive performance of the Bidirectional Encoder Representations from Transformers model was observed using the HCC data set to train and BTC data set to test (mean ROC AUC, 0.940 [SD 0.028]), with similarly high predictive performance using balanced and imbalanced training data sets from BTC and gastric cancer populations.

CONCLUSIONS

NLP models were accurate in predicting multiclass classification of text from interviews of patients with cancer, with most surpassing 0.9 ROC AUC at paragraph level. NLP may be a useful tool for scaling up processing of patient interviews in clinical studies and, thus, could serve to facilitate patient input into drug development and improving patient care.

A rapid review of patient-reported outcomes investigated in the context of advanced renal cell cancer or advanced hepatocellular cancer

BACKGROUND

Patient-reported outcomes (PROs) are key indicators of health status and functioning, coming directly from the patient. Comprehensive monitoring of PROs enables implementation of person-centred care. Currently, the PROs that patients with advanced renal cell carcinoma (RCC) or hepatocellular carcinoma (HCC) consider of greatest importance remains unknown.

METHODS

A rapid literature review was carried out to identify PROs commonly reported in clinical studies of patients with advanced RCC/HCC. We searched MEDLINE, CINAHL & PsycInfo for relevant peer-reviewed publications in the period from 2000 to 2021. Pre-specified selection criteria were applied to all retrieved records. Findings were integrated into a narrative synthesis.

RESULTS

Eighty-one studies met our selection criteria and were retained. Most research was on advanced RCC (n = 64, 79%); 46 studies (57%) were drug trials. Only twenty-six studies (32%) employed PROs as their primary endpoint. Most PROs concerned physical symptoms (45% RCC, 54% HCC) and emotional wellbeing (19% RCC, 16% HCC). The most common outcome measured was quality of life (65% of the total), followed by fatigue (62%) and pain (54%). Whether selection of these PROs was patient-driven was not reported.

CONCLUSIONS

A wide range of PROs were assessed. Deficits in PROs often cause patients to seek out help; however, which PROs matter the most to people with advanced RCC/HCC must be further clarified. Targeting, monitoring, and responding to the 'right' PROs can enhance provision of person-centred care in advanced RCC/HCC and augment the clinical efficacy of established and emerging targeted therapies.

Hepatocellular carcinoma and its impact on quality of life: A review of the qualitative literature

INTRODUCTION

Hepatocellular carcinoma (HCC) carries significant burden of disease, with high mortality rates and poor prognosis. It is therefore important to consider quality of life (QoL) for patients with HCC. Quantitative research assesses HCC and QoL via standardised measurement tools, but these do not capture the full scope of patient experiences. This review examines the body of qualitative research on this topic, to develop a comprehensive understanding of QoL for this population.

METHODS

Medline, EMBASE and PsycINFO were systematically searched with keywords relating to HCC, QoL and patient experience. After applying inclusion and exclusion criteria, key findings of included studies were extracted and analysed for themes.

RESULTS

Eleven studies were included for thematic analysis, with five themes identified as central to QoL: (1) burden of physical symptoms and treatment side effects; (2) psychological impact and coping strategies; (3) social function and stigma; (4) spiritual wellbeing, sense of self and meaning of illness and (5) pervasive uncertainty.

CONCLUSION

HCC profoundly impacted patients' lives, spanning physical, psychological, social and spiritual QoL domains. While QoL was reduced overall, some features of patient experiences that enhanced QoL were noted. The findings complement data from quantitative studies, helping to build a richer understanding of QoL.

Quality Reporting of Systematic Review and Meta-Analysis According to PRISMA 2020 Guidelines: Results from Recently Published Papers in the Korean Journal of Radiology

OBJECTIVE

To evaluate the completeness of the reporting of systematic reviews and meta-analyses published in a general radiology journal using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines.

MATERIALS AND METHODS

Twenty-four articles (systematic review and meta-analysis, n = 18; systematic review only, n = 6) published between August 2009 and September 2021 in the Korean Journal of Radiology were analyzed. Completeness of the reporting of main texts and abstracts were evaluated using the PRISMA 2020 statement. For each item in the statement, the proportion of studies that met the guidelines' recommendation was calculated and items that were satisfied by fewer than 80% of the studies were identified. The review process was conducted by two independent reviewers.

RESULTS

Of the 42 items (including sub-items) in the PRISMA 2020 statement for main text, 24 were satisfied by fewer than 80% of the included articles. The 24 items were grouped into eight domains: 1) assessment of the eligibility of potential articles, 2) assessment of the risk of bias, 3) synthesis of results, 4) additional analysis of study heterogeneity, 5) assessment of non-reporting bias, 6) assessment of the certainty of evidence, 7) provision of limitations of the study, and 8) additional information, such as protocol registration. Of the 12 items in the abstract checklists, eight were incorporated in fewer than 80% of the included publications.

CONCLUSION

Several items included in the PRISMA 2020 checklist were overlooked in systematic review and meta-analysis articles published in the Korean Journal of Radiology. Based on these results, we suggest a double-check list for improving the quality of systematic reviews and meta-analyses. Authors and reviewers should familiarize themselves with the PRISMA 2020 statement and check whether the recommended items are fully satisfied prior to publication.

The impact of hepatocellular carcinoma diagnosis on patients' health-related quality of life

Background

Patients with hepatocellular cancer (HCC) are known to have worse health‐related quality of life (HRQL) than the general population. However, the change in HRQL from before the diagnosis to after diagnosis remains unknown and is difficult to estimate. We aimed to compare HCC cases with matched controls to evaluate the differences in change in HRQL from before to after HCC diagnosis.

Methods

We performed propensity score‐matched analysis using the self‐reported HRQL data from the Surveillance, Epidemiology, and End Results registries (SEER) data linked with Medicare Health Outcomes Survey (MHOS) data (1998–2014). Cases were selected as Medicare beneficiaries (aged ≥65 years) who were diagnosed with HCC between their baseline assessment and follow‐up assessment. Matched controls were selected from the same data resource and the same time period to include subjects without cancer diagnosis by propensity scores. HRQL was assessed using the Medical Outcomes Study Short Form‐36 (SF‐36).

Results

The study included 62 subjects who developed HCC and 365 matched controls. Compared to their baseline HRQL scores, after diagnosis of HCC, subjects were more likely to report declines in scores related to the mental component of HRQL. When stratified by time since diagnosis, mental component remained significantly lower as the disease advanced. In contrast, only general health aspects of physical health worsened after HCC diagnosis.

Conclusions

Diagnosis of HCC has a profound negative impact on patients’ HRQL. Mental health component deteriorated significantly over time. The need of including mental health services within a multidisciplinary HCC care model is clearly evident.

High expression of PARD3 predicts poor prognosis in hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is one of the most commonly cancers with poor prognosis and drug response. Identifying accurate therapeutic targets would facilitate precision treatment and prolong survival for HCC. In this study, we analyzed liver hepatocellular carcinoma (LIHC) RNA sequencing (RNA-seq) data from The Cancer Genome Atlas (TCGA), and identified PARD3 as one of the most significantly differentially expressed genes (DEGs). Then, we investigated the relationship between PARD3 and outcomes of HCC, and assessed predictive capacity. Moreover, we performed functional enrichment and immune infiltration analysis to evaluate functional networks related to PARD3 in HCC and explore its role in tumor immunity. PARD3 expression levels in 371 HCC tissues were dramatically higher than those in 50 paired adjacent liver tissues (p < 0.001). High PARD3 expression was associated with poor clinicopathologic feathers, such as advanced pathologic stage (p = 0.002), vascular invasion (p = 0.012) and TP53 mutation (p = 0.009). Elevated PARD3 expression also correlated with lower overall survival (OS, HR = 2.08, 95% CI = 1.45-2.98, p < 0.001) and disease-specific survival (DSS, HR = 2.00, 95% CI = 1.27-3.16, p = 0.003). 242 up-regulated and 71 down-regulated genes showed significant association with PARD3 expression, which were involved in genomic instability, response to metal ions, and metabolisms. PARD3 is involved in diverse immune infiltration levels in HCC, especially negatively related to dendritic cells (DCs), cytotoxic cells, and plasmacytoid dendritic cells (pDCs). Altogether, PARD3 could be a potential prognostic biomarker and therapeutic target of HCC.

Prognostic significance of systemic immune-inflammation index-based nomogram for early stage hepatocellular carcinoma after radiofrequency ablation

BACKGROUND

Radiofrequency ablation (RFA) is the recommended treatment for early stage hepatocellular carcinoma (HCC), and the prognostic value of systemic immune-inflammation index (SII) in early stage HCC is not discussed. Therefore, the purpose of the study is to explore the prognostic value of SII based on lymphocyte, neutrophil, and platelet counts in patients with HCC after RFA.

METHODS

We retrospectively evaluated the prognostic value of the SII in training and validation cohorts, and then established an effective nomogram for HCC after RFA based on SII. The C-index, and area under the time-dependent receiver operating characteristic curve (t-AUC) were used to evaluate the discrimination and calibration value of the nomogram.

RESULTS

An optimal cut-off value for the SII of 324.55×109 stratified the patients with HCC into high- and low-SII groups. Univariate and multivariate analyses revealed that SII was an independent predictor for overall survival (OS) and recurrence-free survival (RFS). Moreover, SII was an independent prognostic factor for early-stage HCC with normal alpha-fetoprotein (AFP) levels. The t-AUC of the SII was higher for OS and RFS than for neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR). A high preoperative SII was associated with multiple tumors, larger tumors, and higher levels of AFP. A well-discriminated and calibrated nomogram was constructed to predict the probability of 1-, 2-, 3-, and 5-year RFS with C-indexes of 0.80, which was significantly higher than that obtained with other prognostic clinical indexes.

CONCLUSIONS

The SII is an independent prognostic factor affecting the survival outcomes of patients with early-stage HCC. The comprehensive nomogram based on SII presented in this study is a promising model for predicting RFS in HCC patients after RFA.
