Prognostic nutritional index predicts short-term outcomes after liver resection for hepatocellular carcinoma within the Milan criteria

Prognostic Nutritional Index as a Prognostic Factor for Very Early-Stage Hepatocellular Carcinoma

INTRODUCTION

Field factors play more important roles in predicting the outcomes of patients compared with tumor factors in early-stage hepatocellular carcinoma (HCC). However, the prognostic ability of noninvasive serum marker scores for hepatic fibrosis and liver functional reserve on very early-stage HCC is still not yet determined. We aimed to investigate the performance of these serum marker scores in predicting the prognoses of patients with very early-stage HCC.

METHODS

A total of 446 patients with very early-stage HCC from 2012 to 2022 were retrospectively enrolled. Serum biomarkers and prognostic scores determining overall survival (OS) were analyzed by Cox proportional hazards model. We compared the Akaike information criterion among the prognostic nutritional index (PNI), aspartate aminotransferase-to-platelet ratio index, albumin-bilirubin (ALBI) score, EZ (easy)-ALBI score, modified ALBI score, fibrosis-4 score, and lymphocyte-to-monocyte ratio to determine the predictability on the OS.

RESULTS

After a median follow-up of 41.0 months (interquartile range 36.9-45.1 months), 81 patients died, with a 5-year OS rate of 71.0%. Among the noninvasive serum marker scores, PNI had the best performance in predicting the OS with the lowest Akaike information criterion (846.407) compared with other scores. Moreover, we stratified the patients into high-risk (PNI <45) and low-risk (PNI ≥45) groups. It showed that the 5-year OS rates were 83.4% and 60.8% in the low-risk and high-risk PNI groups, respectively ( P < 0.001).

DISCUSSION

PNI had the best performance in predicting the OS for patients with very early-stage HCC.

Malnutrition significantly affected centenarian prognoses: A prospective study with 5-year follow-up

BACKGROUND

The world is currently facing a much-needed conundrum, and population aging has become an important worldwide problem. Appropriate nutritional intervention could prolong survival time and reduce mortality rate. However, scarce study has involved the effects of nutrition on survival time in centenarians and evaluated the malnutrition with prognostic nutritional index (PNI) in relation to healthy aging. This prospective study was designed to investigate the effects of malnutrition through PNI assessment on mortality rate and survival time with 5-year follow-up in Chinese centenarians.

METHODS

A household survey was conducted on the centenarians in 18 cities and counties of Hainan province, and malnutrition was evaluated by PNI as an effective tool in 423 centenarians followed up for 5-year.

RESULTS

Prevalence of malnutrition was 19.4%. Body mass index (BMI) was significantly lower and malnutrition was significantly more in the dead group than those in the survival group (all P < 0.05). Multivariate Cox regression analysis indicated that BMI [Hazard ratio (HR): 0.913; 95%CI: 0.854-0.977] negatively affected mortality rate, whereas malnutrition (HR: 2.630; 95%CI:1.474-4.695) positively affected mortality rate in centenarians (all P < 0.05). When BMI was <18.5 kg/m2, malnutrition (HR: 4.401; 95%CI: 1.948-9.943) also positively affected mortality rate (P < 0.05).

CONCLUSIONS

This prospective study with 5-year follow-up demonstrated that malnutrition had positive effect on mortality rate, especially when BMI was lower than 18.5 kg/m2, in Chinese centenarians. In order to reduce mortality rate and prolong survival time, it is essential to pay attention to malnutrition in elderly population.

A Single Centre Experience with Pre-Operative Markers in the Prediction of Outcomes after Liver Resection for Hepatocellular Carcinoma

BACKGROUND AND AIM

The C-reactive protein to albumin ratio, albumin-bilirubin index and platelet-albumin-bilirubin index have emerged as prognostic scores in hepatocellular carcinoma, although their clinical utility remains unclear, with ongoing investigation in multiple patient populations. This study aims to report survival outcomes and evaluate these indices in a cohort of patients undergoing liver resection for hepatocellular carcinoma in a tertiary Australian centre.

METHODS

This retrospective study reviewed data from the Department of Surgery at Austin Health and electronic health records (Cerner corporation). The impact of pre, intra and post-operative parameters on post-operative complications, overall and recurrence free survival were analyzed.

RESULTS

163 liver resections were performed in 157 patients between 2007 and 2020. Post-operative complications occurred in 58 patients (35.6%), with pre-operative albumin < 36.5 g/L (3.41(1.41-8.29),p = 0.007) and open liver resection (3.93(1.38-11.21),p = 0.011) demonstrating independent predictive significance. 1,3 and 5-year overall survival was 91.0%, 76.7% and 66.9% respectively, with a median survival time of 92.7 months (81.3-103.9). Hepatocellular carcinoma recurred in 95 patients (58.3%) with a median time to recurrence of 27.8 months (15.6-39.9). 1,3 and 5 year recurrence-free survival rates were 94.0%, 73.7% and 55.1% respectively. Pre-operative C-reactive protein-albumin ratio > 0.034 was significantly associated with reduced overall (4.39(1.19-16.16),p = 0.026) and recurrence-free (2.53(1.21-5.30),p = 0.014) survival.

CONCLUSION

C-reactive protein-albumin ratio > 0.034 is a strong predictor of poor prognosis following liver resection for hepatocellular carcinoma. In addition, pre-operative hypoalbuminemia was associated with post-operative complications, and future studies are required to assess the potential benefits of albumin replacement in reducing post-surgical morbidity.

Prognostic nutritional index value in the prognosis of Kawasaki disease with coronary artery lesions

Objectives

The prognostic nutritional index (PNI) is a purported predictor of intravenous immunoglobulin (IVIG) resistance and coronary artery aneurysm (CAA) development in patients with Kawasaki disease (KD). However, limited data exist on CAA regression. This study aimed to confirm whether the PNI is a predictor for CAA persistency in patients with KD.

Methods

This retrospective study grouped 341 patients with KD based on the coronary artery status and time of aneurysm persistence. The clinical and laboratory parameters were compared, and multivariate logistic regression analysis was performed to identify the independent risk factors for persistent CAA. The receiver operating characteristic (ROC) curve was further used to assess the predictive values of the PNI in persistent CAA.

Results

Among the study patients, 80 (23.5%) presented with CAA, including CAA persisting for 2 years in 17 patients (5.0%). Patients with CAA were more frequently treated with corticosteroids (p < 0.016). No statistically significant differences were found in the nutritional status and PNI among patients with or without coronary artery lesions, regardless of injury severity. Patients in the persistent CAA group presented with higher rates of overnutrition and showed lower PNI values and a higher incidence of thrombosis than those in the normal group (p < 0.05). The PNI and the maximum Z-score at 1 month of onset were significantly associated with CAA persisting for 2 years and may be used as predictors of persistent CAA. The area under the ROC curve was 0.708 (95% confidence interval, 0.569-0.847), and a 40.2 PNI cutoff yielded a sensitivity and specificity of 41 and 92%, respectively, for predicting CAA persisting for 2 years. Kaplan-Meier survival analysis revealed that the estimated median time of aneurysm persistence was significantly higher in patients with PNI values of ≤40 than in those with PNI values of >40 (hazard ratio, 2.958; 95% confidence interval, 1.601-5.464; p = 0.007). After sampling-time stratification, the PNI differed significantly between patients with and without persistent CAA when sampled on the second (p = 0.040), third (p = 0.028), and fourth days (p = 0.041) following disease onset.

Conclusion

A lower PNI value is an independent risk factor for CAA persisting for 2 years in patients with KD, besides the maximum Z-score at 1 month after onset. Furthermore, the PNI obtained within 4 days from fever onset may possess greater predictive power for patients with persistent CAA.

Combination of sarcopenia and prognostic nutritional index to predict long-term outcomes in patients undergoing initial hepatectomy for hepatocellular carcinoma

OBJECTIVE

To determine if preoperative sarcopenia and prognostic nutritional index (PNI) could accurately predict the postoperative outcomes of patients with hepatocellular carcinoma (HCC) undergoing initial hepatectomy.

METHODS

Three hundred three patients who underwent curative hepatectomy for HCC between January 2010 and August 2021 were enrolled and their data were retrospectively analyzed. Sarcopenia was determined from computed tomography images obtained 3 weeks prior to surgery, and PNI was calculated from preoperative albumin and whole lymphocyte count data in receiver operating characteristic (ROC) curve analysis, with a cutoff value of 46.2 to categorize high and low groups.

RESULTS

One hundred six (35%) patients had sarcopenia prior to surgery. Kaplan-Meier analysis revealed that sarcopenia and low PNI were associated with significantly worse overall survival (OS) compared with no sarcopenia and high PNI, respectively (P = 0.023 and P = 0.035, respectively). In addition, patients with sarcopenia had worse OS than those without sarcopenia in the high and low PNI groups (P = 0.058 and P = 0.038, respectively). Sarcopenia (hazard ratio [HR] 1.66; 95% confidence interval [CI] 1.00-2.76; P = 0.048) and PNI ≤46.2 (HR 1.96; 95% CI 1.17-3.27; P = 0.011) were independent prognostic factors on multivariate analysis, and combined sarcopenia and PNI had a higher AUC value (AUC = 0.722, P < 0.001) than either one alone in ROC analysis.

CONCLUSION

Combined sarcopenia and PNI as a prognostic marker can better predict the postoperative prognostic outcomes of HCC patients following hepatectomy than either sarcopenia or PNI alone.

The impact of preoperative nutrition status on abdominal surgery outcomes: A prospective cohort study

BACKGROUND

The European Society for Clinical Nutrition and Metabolism recommends nutrition screening using the Mini Nutritional Assessment Short-Form (MNA-SF) in older adult patients preoperatively. However, the association of nutrition condition with postoperative complications is poorly documented. We aimed to identify preoperative nutrition status using the MNA-SF and to determine whether preoperative nutrition status affects postoperative outcomes.

METHODS

Inpatients aged ≥55 years who underwent elective abdominal surgery under general anesthesia between April 1, 2016, and December 28, 2018, were included. We assessed nutrition status using the MNA-SF before surgery. Multiple logistic regression including the MNA-SF score was applied to determine associated factors with our primary outcome, postoperative complications defined as Clavien-Dindo classification ≥3a. Secondary outcomes including length of hospital stay and unplanned readmission were compared between normal, at risk, and malnourished patients.

RESULTS

The data of 1248 patients with a mean age of 69 years were analyzed. The prevalence of at risk and malnutrition was 33.0% (412 of 1248) and 6.9% (87 of 1248), respectively. Overall, 12.4% (155 of 1248) had major postoperative complications, and the MNA-SF score was a significant predictor (odds ratio: 0.92, 95% CI: 0.86-0.99) after adjusting for confounders. Patients at risk of malnutrition and those with malnutrition had a longer hospital length of postoperative stay than normal patients (P = 0.001); however, there was no statistical significance in unplanned readmission rate between the three groups (P = 0.14).

CONCLUSION

Preoperative nutrition disorder was common, and it affected postoperative adverse outcomes. The MNA-SF score was associated with major postoperative complications.

Prognostic Nutritional Index and Neutrophil/Lymphocyte Ratio Can Serve as Independent Predictors of the Prognosis of Hepatocellular Carcinoma Patients Receiving Targeted Therapy

Objective

The prognostic nutritional index (PNI) is an immunonutritional indicator, and the neutrophil/lymphocyte ratio (NLR) reflects the inflammatory status. This research intends to determine the implications of NLR and PNI in evaluating the outcome of hepatocellular carcinoma (HCC) patients undergoing targeted therapy (TT).

Methods

We retrospectively analyzed 83 patients' records with sorafenib treatment for advanced HCC in the Second Affiliated Hospital of Anhui Medical University. Patient records comprised general data and blood routines. The PNI and NLR values were calculated using the serum albumin levels (ALB), neutrophil (NEU) count, and lymphocyte (LY) count. The optimal thresholds of the PNI and NLR for predicting HCC patients' outcomes were calculated by X-tile. Patients were further assigned to low- and high-groups of PNI and NLR according to their thresholds. By using the Cox proportional hazards regression models, univariate and multivariate analyses were conducted to identify risk factors influencing the patient's prognosis.

Results

The participants were assigned to the corresponding low-PNI (≤42.9; n = 10) and high-PNI (>42.9; n = 73) groups, as well as low-NLR (≤2.4; n = 64) and high-NLR (>2.4; n = 19) groups based on the critical values of PNI (42.9) and NLR (2.4) obtained through the X-tile calculation. A higher overall survival (OS) rate was observed in the high-PNI group and low-NLR group, than in the low-PNI group and high-NLR group, respectively. The disease control rate showed no evident difference between the groups. The PNI and NLR were of high reliability in predicting the OS of patients. Cox multivariate analysis identified the independence of the PNI and NLR as prognostic factors for patients receiving TT for advanced HCC.

Conclusions

The pretreatment PNI and NLR levels have great prognostic implications for advanced HCC patients receiving TT. A higher PNI and a lower NLR suggest a higher postoperative survival rate.

A predictive model incorporating inflammation markers for high-grade surgical complications following liver resection for hepatocellular carcinoma

BACKGROUND

Systemic inflammation and immune deficiency predispose surgical patients to infection and adversely affect postoperative recovery. We aimed to evaluate the prognostic ability of inflammation and immune-nutritional markers and to develop a predictive model for high-grade complications after resection of hepatocellular carcinoma (HCC).

METHODS

This study enrolled 1431 patients undergoing liver resection for primary HCC at a medical center. Preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, prognostic nutritional index, Model for End-Stage Liver Disease score, Albumin-Bilirubin score, Fibrosis-4 score, and Aspartate Aminotransferase to Platelet Ratio Index score were assessed. Stepwise backward variable elimination was conducted to determine the factors associated with Clavien-Dindo grade III to V complications within 30-day postoperative period. The predictive model was internally validated for discrimination performance using area under the receiver operating characteristic curve (AUC).

RESULTS

A total of 106 (7.4%) patients developed high-grade complications. Four factors independently predicted a high-grade postoperative complication and were integrated into the predictive model, including NLR (adjusted odds ratio: 1.10, 95% confidence interval [CI], 1.02-1.19), diabetes mellitus, extent of hepatectomy, and intraoperative blood loss. The AUC of the model was 0.755 (95% CI, 0.678-0.832) in the validation dataset. Using the cutoff value based on Youden's index, the sensitivity and specificity of the risk score were 59.0% and 76.3%, respectively.

CONCLUSION

Preoperative NLR independently predicted a high-grade complication after resection of HCC. The predictive model allows for identification of high-risk patients and appropriate modifications of perioperative care to improve postoperative outcomes.

Serum carnitine as a biomarker of sarcopenia and nutritional status in preoperative gastrointestinal cancer patients

BACKGROUND

Sarcopenia is an important factor in the postoperative outcome of gastrointestinal cancer patients. However, little research has been carried out on potential biomarkers of sarcopenia. Carnitine is an amino acid derivative that is stored in skeletal muscle and is essential for muscle energy metabolism. The primary purpose of this study was to investigate whether serum carnitine level is a biomarker of sarcopenia in preoperative patients with gastrointestinal cancer. The secondary purposes were (i) to examine the associations between carnitine, nutritional status, and albumin level, and (ii) to determine whether carnitine is a prognostic factor for postoperative complications.

METHODS

One hundred fourteen patients scheduled to undergo gastroenterological surgery between August 2016 and January 2017 were enrolled. Their mean age was 68.4 ± 10.5, and 64.9% were male. Serum carnitine fractions [total carnitine (TC), free l-carnitine (FC), and acylcarnitine (AC)] were measured prior to surgery. The correlation between carnitine level and a variety of clinical features was analysed, including skeletal muscle index (SMI), sarcopenia, prognostic nutritional index (PNI), and postoperative complications.

RESULTS

Tumour locations included the oesophagus (n = 17), stomach (n = 16), pancreas (n = 20), bile duct (n = 9), liver [n = 33; primary liver cancer (n = 18), liver metastasis (n = 15)], and colorectal region (n = 19). TC and FC levels varied significantly by tumour location. TC and FC showed significant positive correlations with SMI [TC (r = 0.295, P = 0.0014), FC (r = 0.286, P = 0.0020)] and PNI [TC (P = 0.0178, r = 0.222), FC (P = 0.0067, r = 0.2526)]. These levels were significantly lower in the sarcopenia group (TC, P = 0.0124; FC, P = 0.0243). In addition, TC and FC showed significant positive correlations with ALB level [TC (P = 0.038 r = 0.19), FC (P = 0.016 r = 0.23)]. When patients were divided into high ALB (≥3.5 g/dL, 96 patients) and low ALB (<3.5 g/dL, 18 patients) groups, these correlations were no longer significant, but in the low ALB group there was a tendency towards a negative relationship between ALB level and both TC and FC. No significant relationship was found between postoperative complications and carnitine level.

CONCLUSIONS

This study suggests that carnitine level is a biomarker of sarcopenia and nutritional status. However, it did not find an association between carnitine level and postoperative complications.

Prevalence of undernutrition in surgical patients and the effect on length of hospital stay

BACKGROUND

Low nutritional status is common among surgical patients. A low nutrition profile is related to muscle weakness and immune suppression, which may be associated with negative outcomes. In this study, we evaluated the prevalence of low nutrition and assessed the relationship between nutritional status and length of hospital stay in surgical patients.

METHODS

The study participants were patients who underwent abdominal surgery between 2016 and 2018 at our hospital. The Mini Nutritional Status Short-Form score and patient demographics, including current medical status, were extracted from the medical records. Data on anesthesia time, blood loss, and use of epidural anesthesia were also recorded. The primary study outcome was the difference in length of hospitalization from the standard duration (hospitalization = actual length of hospitalization-standard length of hospitalization).

RESULTS

Eight hundred and thirty five patients met the inclusion criteria. Their nutritional status was classified as normal (59.0%), at risk (29.6%), or malnutrition (11.4%). Linear regression analysis revealed that nutritional status, serum albumin level, and anesthesia time were associated with the length of hospital stay.

CONCLUSION

Our results suggest that a low nutrition profile before surgery is associated with a prolonged hospital stay.

Gastrectomy history as a predictor of post-hepatectomy complications

PURPOSE

The effect of a history of gastrectomy on patients undergoing hepatectomy is unclear. We investigated the relationship between postoperative complications of Clavien-Dindo grade III or higher and a history of gastrectomy in patients undergoing hepatectomy.

METHODS

The subjects of this retrospective analysis were 474 consecutive patients who underwent hepatectomy at our institute for hepatic malignancy, classified into groups of those with or without a history of gastrectomy and those with or without postoperative complications. We compared the clinicopathological factors between the groups.

RESULTS

There were no hospital deaths. Gastrectomy history was identified in 22 patients (4.6%) and was significantly associated with advanced age, low body mass index, male sex, decreased serum albumin level, decreased hemoglobin level, low PNI, low CONUT score, high incidence of postoperative complications, and longer hospital stay. Multivariate analyses revealed that the independent risk factors for postoperative complications were gastrectomy history, an albumin-bilirubin score of 2/3, primary liver cancer, high serum creatinine level, advanced age, and prolonged operation time.

CONCLUSIONS

Gastrectomy history was an independent predictor of postoperative complications in patients undergoing hepatectomy for hepatic malignancies. Patients with a history of gastrectomy were likely to suffer postoperative bile leakage and pneumonia.

Preoperative prognostic nutritional index predicts postoperative infectious complications and oncological outcomes after hepatectomy in intrahepatic cholangiocarcinoma

Background

In the surgical treatment of intrahepatic cholangiocarcinoma (ICC), postoperative complications may be predictive of long-term survival. This study aimed to identify an immune-nutritional index (INI) that can be used for preoperative prediction of complications.

Patients and methods

Multi-institutional data from 316 patients with ICC who had undergone surgical resection were retrospectively analysed, with a focus on various preoperative INIs.

Results

Severe complications (Clavien-Dindo grade III–V) were identified in 66 patients (20.8%), including Grade V complications in 7 patients (2.2%). Comparison of areas under the receiver operating characteristic curve (AUCs) among various INIs identified the prognostic nutritional index (PNI) as offering the highest predictive value for severe complications (AUC = 0.609, cut-off = 50, P = 0.008). Multivariate analysis revealed PNI <  50 (odds ratio [OR] = 2.22, P = 0.013), hilar lesion (OR = 2.46, P = 0.026), and long operation time (OR = 1.003, P = 0.029) as independent risk factors for severe complications. In comparing a high-PNI group (PNI ≥ 50, n = 142) and a low-PNI group (PNI <  50, n = 174), the low-PNI group showed higher rates of both major complications (27% vs. 13.4%; P = 0.003) and infectious complications (14.9% vs. 3.5%; P = 0.0021). Furthermore, median survival time and 1- and 5-year overall survival rates were 34.2 months and 77.4 and 33.8% in the low-PNI group, respectively, and 52.4 months and 89.3 and 47.5% in the high-PNI group, respectively (P = 0.0017).

Conclusion

Preoperative PNI appears useful as an INI correlating with postoperative severe complications and as a prognostic indicator for ICC.

Cancer related nutritional and inflammatory markers as predictive parameters of immediate postoperative complications and long-term survival after hepatectomies

BACKGROUND

The overall survival (OS), disease-free survival (DFS) and complications after liver resections is unsatisfactory. Cancer-related malnutrition and inflammation have an effect on survival but not studied/not clear on postoperative complications.

METHODS

We retrospectively analyzed prospectively maintained database of 309 patients. The outcome variables included complications in terms of Clavien-Dindo (CD) Score, OS and DFS; We studied effect of preoperative albumin globulin ratio (AGR), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and aspartate transaminase to platelet ratio index (APRI) and dynamic change from pre-operative to postoperative value (Delta-AGR, Delta-NLR, Delta-PLR and Delta-APRI) on complications, OS and DFS.

RESULTS

Total 98 patients (31.71%) had postoperative complications. Fifty patients had CD 1 & 2 and 35 (11.33%) had CD 3 & 4, and 13 (4.12%) had mortality (CD 5). Low AGR, high NLR, high PLR and high Delta-AGR and high Delta-APRI predicted increased major complications. Preoperative high NLR predicted worse OS and low AGR predicted worse OS and DFS. Delta-APRI showed trends towards worse OS and DFS.

CONCLUSION

These serum inflammatory markers can predict immediate postoperative complications. Preoperative AGR and preoperative NLR can predict survival after liver resections. High Delta-AGR, which is a new entity, is predicting more postoperative complications and needs further detailed studies.

The Association between Prognostic Nutritional Index (PNI) and Intraoperative Transfusion in Patients Undergoing Hepatectomy for Hepatocellular Carcinoma: A Retrospective Cohort Study

BACKGROUND

PNI is significantly associated with surgical outcomes; however, the association between PNI and intraoperative transfusions is unknown.

METHODS

This study retrospectively analyzed 1065 patients who underwent hepatectomy. We divided patients into two groups according to the PNI (<44 and >44) and compared their transfusion rates and surgical outcomes. We performed multivariate logistic and Cox regression analysis to determine risk factors for transfusion and the 5-year survival. Additionally, we found the net reclassification index (NRI) to validate the discriminatory power of PNI.

RESULTS

The PNI <44 group had higher transfusion rates (adjusted odds ratio [OR]: 2.20, 95%CI: 1.06-4.60, p = 0.035) and poor surgical outcomes, such as post hepatectomy liver failure (adjusted [OR]: 3.02, 95%CI: 1.87-4.87, p < 0.001), and low 5-year survival (adjusted OR: 1.68, 95%CI: 1.17-2.24, p < 0.001). On multivariate analysis, PNI <44, age, hemoglobin, operation time, synthetic colloid use, and laparoscopic surgery were risk factors for intraoperative transfusion. On Cox regression analysis, PNI <44, MELD score, TNM staging, synthetic colloid use, and transfusion were associated with poorer 5-year survival. NRI analysis showed significant improvement in the predictive power of PNI for transfusion (p = 0.002) and 5-year survival (p = 0.004).

CONCLUSIONS

Preoperative PNI <44 was significantly associated with higher transfusion rates and surgical outcomes.

Prognostic Nutritional Index Considering Resection Range Is Useful for Predicting Postoperative Morbidity of Hepatectomy

BACKGROUND

Poor preoperative nutritional and immunological status are major risk factors for postoperative complications in patients with various malignancies. Lower preoperative prognostic nutrition index (PNI) is associated with higher rates of postoperative complications and poorer prognosis in those patients. The aim of this study was to analyze the predictive value of the PNI for post-hepatectomy complications in patients with hepatocellular carcinoma (HCC), and evaluate its utility in the surgical procedure.

METHODS

This retrospective study included 510 patients who underwent open hepatectomies for HCC. The predictive value of the preoperative nutritional and immunological status for postoperative complications was assessed using the PNI. Postoperative complications were defined as grade II or higher per the Clavien-Dindo classification. Postoperative complication rates were compared according to surgical procedure (major hepatectomy vs minor hepatectomy).

RESULTS

Patients with postoperative complications had significantly lower PNIs than those without (43.1 ± 5.5 vs 47.0 ± 5.7, P < 0.001). In the multivariate analysis, low preoperative PNI (< 45) was an independent risk factor for postoperative complications after hepatectomy (hazard ratio, 3.85). When patients were classified per their PNI (high vs low) and extent of surgical procedures (major vs minor), there were more complications among patients with low PNI than those with high PNI, regardless of the extent of surgical procedures. Specifically, the group of patients with low PNI who underwent major hepatectomy had significantly higher rates of postoperative complications than the other groups.

CONCLUSIONS

Adding the resection range to the PNI is useful for predicting the postoperative morbidities of hepatectomy patients.

Preoperative prognostic nutritional index predicts short- and long-term outcomes after liver resection in patients with hepatocellular carcinoma

The prognostic nutritional index (PNI) is one of the immune parameters calculated on the basis of the serum albumin and the total lymphocyte count. The aim of the present study was to investigate the prognostic significance of the PNI for short- and long-term outcomes after liver resection for patients with hepatocellular carcinoma (HCC). Data from 162 surgically treated patients with HCC (without any previous treatment) were retrospectively analyzed. The cutoff value of preoperative PNI was 45.0, which was calculated by a receiver operating characteristic curve for predicting the recurrence of HCC after liver resection. Patients were divided into low (n=86) and high (n=76) PNI groups. In short-term outcomes, patients in the low PNI group were more likely to experience postoperative complications compared with those in the high PNI group. The 5-year disease-free survival (DFS) rate in the low PNI group was significantly lower compared with that in the high PNI group (20.5% vs. 48.7%). In the multivariate analysis, a low PNI was an independent prognostic factor for DFS (HR, 1.65; 95% CI, 1.00-2.71). In conclusion, the preoperative PNI may be a prognostic factor for evaluating short- and long-term outcomes after liver resection in patients with HCC.

Preoperative Albumin-Bilirubin Grade With Prognostic Nutritional Index Predicts the Outcome of Patients With Early-Stage Hepatocellular Carcinoma After Percutaneous Radiofrequency Ablation

Background: Prognostic nutritional index (PNI) that was designed to assess the nutritional and immunological status of patients and albumin–bilirubin (ALBI) grades can be used as an assessment tool for hepatic function. Both nutritional and immunological statuses have been reported to be independent prognostic factors of patients with hepatocellular carcinoma (HCC). This study aimed to investigate whether PNI together with ALBI could be a better predictor in patients with early-stage HCC undergoing radiofrequency ablation (RFA).

Method: The information of 110 patients with newly diagnosed HCC within the Milan criteria receiving RFA as the initial therapy between 2014 and 2015 was retrospectively collected. Pretreatment PNI, ALBI, and PNI-ALBI grades were calculated. Overall survival (OS) and recurrence-free survival (RFS) were estimated by the Kaplan–Meier method, and multivariate analysis was used to identify prognostic factors.

Result: The 1-, 3-, and 5-years OS rates of patients were 80.0, 30.9, and 23.9%, respectively. Multivariate analysis showed that the tumor size [hazard ratio (HR) = 1.966, 95% confidence interval (CI) = 1.091–3.545, P = 0.025], PNI grade (H = 2.558, 95% CI = 1.289–5.078, P = 0.007), and PNI-ALBI grade (HR = 3.876, 95% CI = 1.729–8.690, P = 0.001) were independent risk factors for OS, whereas only the elevated α-fetoprotein (HR = 1.732, 95% CI = 1.003–2.991, P = 0.049) and the size of the tumor (HR = 1.640, 95% CI = 1.015–2.647, P = 0.43) were independent predictors for better RFS.

Conclusion: This study demonstrates that preoperative PNI-ALBI grade is a simple and useful predictor for OS in patients with early-stage HCC after RFA.

A new sarcopenia score prognostic for postoperative complications in hepatic alveolar echinococcosis: a multicenter retrospective study

Background

Skeletal muscle depletion and excessive visceral adipose tissue have been shown to be independent risk factors for postoperative complications (PCs) in various diseases. However, their impact on surgical PCs in hepatic alveolar echinococcosis (HAE) is still unknown.

Methods

We retrospectively reviewed the clinical data of HAE patients who underwent liver resection at our hospital between January 2008 and December 2018. We segmented skeletal muscle and adipose tissue and measured the area of skeletal muscle tissue and adipose tissue at the level of the third lumbar vertebra by manual tracing from preoperative plain computed tomography (CT) images. Sarcopenia features were selected to construct a formula based on the least absolute shrinkage and selection operator (LASSO) logistic regression model in the primary set. Then, integrating the results of multiple clinicopathologic characteristics, we built a nomogram for predicting major PCs in HAE. The results were validated using bootstrap resampling and clinical data from other HAE centers in western China.

Results

The sarcopenia score is based on the personalized levels of the five features from the primary set (n=233). In the multivariate logistic analysis of the primary set, the independent factors for PCs were γ-glutamyl transferase (GGT), and surface area of hepatectomy, which were integrated into the nomogram combined with sarcopenia score. The model had a good prediction capability with a C-index of 0.84 (95% CI, 0.72–0.96). The calibration plot for the probability of PCs showed an optimal agreement between the nomogram predictions and actual observations in the primary and validation sets.

Conclusion

Our study showed that sarcopenia score was significantly correlated with PCs in patients with HAE. In addition, we constructed a prognostic nomogram for predicting complications in HAE patients after liver surgery. The nomogram displayed excellent discrimination and calibration. Improving the nutritional status and physical health of patients before surgery might reduce the incidence of postoperative complications for the high-risk patients.

Prognostic Significance of Preoperative Controlling Nutritional Status Score in Patients Who Underwent Hepatic Resection for Hepatocellular Carcinoma

Malnutrition is common in patients with hepatocellualar carcinoma (HCC), and is associated with postoperative complications after hepatectomy, and also increased mortality. However, there is currently no recommendation for assessment of nutritional status in HCC patients. The controlling nutritional status (CONUT) score has been correlated with prognosis in gastrointestinal cancer patients, but there are few reports on the prognostic significance of the CONUT score in patients who underwent hepatectomy for HCC. Existing results show that patients with high CONUT scores who undergo hepatectomy for HCC have poorer survival outcomes, and experience more complications than other patients. In this paper, we review the literature, and reveal that patients who underwent hepatectomy for HCC with high preoperative CONUT scores had poorer outcomes than those with low CONUT scores. Therefore, we conclude that a preoperative CONUT score may be useful for prognostic prediction in patients with HCC undergoing curative hepatectomy.

Prospective study to evaluate the prognostic value of different nutritional assessment scores in liver surgery: NURIMAS Liver (DRKS00006340)

Background

Malnutrition is recognised as a preoperative risk factor for patients undergoing hepatic resection. It is important to identify malnourished patients and take preventive therapeutic action before surgery. However, there is no evidence regarding which existing nutritional assessment score (NAS) is best suited to predict outcomes of liver surgery.

Methods

All patients scheduled for elective liver resection at the surgical department of the University Hospital of Heidelberg and the Municipal Hospital of Karlsruhe were screened for eligibility. Twelve NASs were calculated before operation, and patients were categorised according to each score as being either at risk or not at risk for malnutrition. The association of malnutrition according to each score and occurrence of at least one major complication was the primary endpoint, which was achieved using a multivariate logistic regression analysis including established risk factors in liver surgery as covariates.

Results

The population consisted of 182 patients. The percentage of patients deemed malnourished by the NAS varied among the different scores, with the lowest being 2.20% (Mini Nutritional Assessment) and the highest 52.20% (Nutritional Risk Classification). Forty patients (22.0%) had a major complication. None of the scores were significantly associated with major complications.

Conclusions

None of the twelve investigated NAS defined a state of malnutrition that was independently associated with postoperative complications. Other means of measuring malnutrition in liver surgery should be investigated prospectively.

Prognostic nutrition index as a predictor of coronary artery aneurysm in Kawasaki Disease

Background

Kawasaki Disease (KD) is considered a major acquired heart disease in children under the age of 5. Coronary artery aneurysm (CAA) can occur in serious cases despite extreme therapy efforts. Previous studies have reported low serum albumin level was associated with disease outcome, but no further investigation was addressed yet.

Method

This retrospective (case-control) study randomly included children with KD who were admitted and underwent laboratory tests before undergoing IVIG treatment in this institution, the largest tertiary medical center in southern Taiwan from 2012 to 2016. Prognostic nutrition index (PNI), an albumin-based formula product, was evaluated as a predictor of CAA the first time. The progression of CAA was monitored using serial echocardiography for six months. We performed multivariable logistic regression analysis on the laboratory test and PNI with the disease outcome of the KD patients.

Result

Of the 275 children, 149 had CAA, including transient dilatation, while the other 126 did not develop CAA during the 6-month follow-up period. A multivariate logistic regression model revealed that PNI, gender, IVIG non-responder, and platelet count are significant predictors of CAA with a 95% confidence interval estimator of 1.999, 3.058, 3.864 and 1.004, respectively. Using PNI to predict CAA presence gave an area under the receiver-operating-characteristics (ROC) curve of 0.596. For a cutoff of 0.5 in the logistic regression model and the PNI cut-off point is taken as 55 together with IVIG non-responder, boy gender, and platelet count take into account, sensitivity and specificity were 65.7 and 70.4%.

Conclusion

PNI could be a candidate of adjunctive predictor of coronary artery aneurysm in addition to IVIG non-responder. Together with low PNI, IVIG non-responder, male gender and platelet count will give high odds to predict coronary artery aneurysm within 6 months of illness.

Preoperative prognostic nutritional index as a method to predict postoperative complications after major head and neck surgery with free tissue transfer reconstruction

Background

Head and neck (H&N) cancer patients are often malnourished and have diminished immunity. H&N surgery with free tissue transfer reconstruction (HNS-FTTR) is associated with a relatively high incidence of postoperative complications.

Methods

Associations between possible risk factors and postoperative Clavien–Dindo (C–D) grades ≥ II and ≥ IIIa wound healing- or infection-related complications, postoperative overall complications and prolonged hospital stay were investigated in 188 patients who underwent HNS-FTTR during 2014–2018. The preoperative prognostic nutritional index (PNI) was calculated using the serum albumin level and total lymphocyte count.

Results

C–D ≥ II and ≥ IIIa complications were seen in 66 (35.1%) and 37 (19.7%) patients, respectively. Multivariate analysis showed that (i) previous irradiation was significantly associated with C–D ≥ II wound healing- or infection-related complications and prolonged hospital stays [odds ratio (OR) 3.096 and 3.328; P = 0.007 and 0.008, respectively]; and (ii) operation time of ≥9 h 20 min was a significant risk factor for C–D ≥ IIIa wound healing- or infection-related complications, and C–D ≥ IIIa overall complications (OR 2.987 and 2.257; P = 0.021 and 0.047, respectively). (3) Only preoperative PNI ≤ 40 was associated with all occurrences of C–D ≥ II and ≥ IIIa wound healing- or infection-related complications, C–D ≥ II and ≥ IIIa overall complications, and prolonged hospital stays (OR 3.078, 2.918, 2.627, 3.132 and 3.116; P = 0.020, 0.046, 0.036, 0.023 and 0.025, respectively).

Conclusions

PNI, easily calculated, was the lone risk factor significantly predicting all C–D ≥ II and ≥ IIIa postoperative wound healing- or infection-related complications, C–D ≥ II and ≥ IIIa postoperative overall complications and prolonged hospital stay after HNS-FTTR.

High CONUT score predicts poor survival and postoperative HBV reactivation in HBV-related hepatocellular carcinoma patients with low HBV-DNA levels

BACKGROUND

Postoperative hepatitis B virus (HBV) reactivation (PHR) is associated with resection-induced immunosuppression in patients with HBV-related hepatocellular carcinoma (HCC). Controlling Nutritional Status (CONUT) score is an effective index for evaluating immune-nutrition function. However, the value of COUNT in predicting PHR in HBV-HCC patients remains unknown.

METHODS

Totally, 209 HCC patients were enrolled.

RESULTS

Preoperative immune function (CD3⁺CD4⁺, CD3⁺CD8⁺, IgG and IgM) in patients with high CONUT score was significantly worse than that in patients with low CONUT score (P<0.05). Blood test results on postoperative day 7 showed the same trend. In addition, patients with high CONUT score experienced a significantly larger decrease in the proportions of CD3⁺CD4⁺ and CD3⁺CD8⁺ than those with low CONUT score (P < 0.05). In patients with high CONUT score, the incidence of overall complications was also significantly higher (P = 0.029) and hospital-stay was significantly longer (P = 0.020). Besides, overall survival and recurrence free survival in patients with high CONUT score were significantly worse than those in patients with low CONUT score (48.32 vs. 38.12 months, P<0.001; 36.08 vs. 27.03 months, P = 0.001). The incidence of PHR was significantly higher in patients with high COUNT score (P<0.001), and CONUT score was strongly associated with PHR (P<0.001). Additionally, the fellow subgroup results also demonstrated that COUNT score was more effective in predicting PHR in patients with HBV-DNA level <500 copies/ml than patients with HBV-DNA 500-1000 copies/ml.

CONCLUSION

CONUT score is an effective indicator predicting survival and PHR in HBV-HCC patients, especially in those with HBV-DNA levels <500 copies/ml.

Pretreatment Inflammation-Based Markers Predict Survival Outcomes in Patients with Early Stage Hepatocellular Carcinoma After Radiofrequency Ablation

The prognostic significance of various systemic inflammation‐based markers has been explored in different cancers after surgery. This study aimed to investigate whether these markers could predict outcomes in patients with early-stage hepatocellular carcinoma (HCC) undergoing radiofrequency ablation (RFA). One hundred eighteen patients with newly diagnosed HCC within the Milan criteria receiving RFA as initial therapy were retrospectively enrolled. Pretreatment inflammation-based markers including the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and prognostic nutritional index (PNI), together with other clinicopathologic parameters were collected. Cumulative overall survival (OS) and recurrence-free survival (RFS) were estimated by the Kaplan-Meier method and by multivariate analysis using Cox proportional hazard model. The 1-, 3-, and 5-year OS rates of patients were 90%, 67%, and 52%, respectively. Kaplan-Meier curves showed that baseline high NLR ≥ 2.5 (p = 0.006), low PNI < 40 (p = 0.005), history of end-stage renal disease (ESRD) (p = 0.005), non-Child-Pugh class A (p = 0.001) and elevated alpha-fetoprotein (AFP) ≥ 200 ng/mL (p = 0.005) significantly associated with the poor OS, whereas high PLR ≥ 100 did not. By multivariate analysis, high NLR ≥ 2.5 (hazard ratio (HR) 1.94; 95% confidence interval (CI), 1.05–3.59; p = 0.034), low PNI < 40 (HR 0.38; 95% CI, 0.20–0.72; p = 0.003), ESRD history (HR 3.60; 95% CI, 1.48–8.76; p = 0.005) and elevated AFP ≥ 200 ng/mL (HR 4.61; 95% CI, 1.75–12.13; p = 0.002) were independent factors. An elevated AFP level of ≥200 ng/mL was the significant factor associated with intrahepatic new RFS by univariate and multivariate analyses. In conclusion, pretreatment NLR and PNI are simple and useful predictors for OS in patients with early-stage HCC after RFA.

Prognostic role of inflammatory biomarkers in HIV-infected patients with a first diagnosis of hepatocellular carcinoma: A single-center study

OBJECTIVES

To assess hepatocellular carcinoma (HCC) survival and to investigate the prognostic role of immunonutritional biomarkers, as neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and prognostic nutritional index (PNI), in a cohort of human immunodeficiency virus (HIV)-infected patients.

METHODS

All HIV-positive patients diagnosed with HCC at our Department from January 2000 to December 2013 were included. The outcomes were overall survival (OS), recurrence-free survival (RFS), and liver-related death (LRD). To examine the role of inflammatory biomarkers on the outcomes, univariate and multivariable Cox regression models were used. Receiver operating characteristic (ROC) curves were implemented to evaluate the prediction role of NLR, PLR, and PNI.

RESULTS

A total of 40 patients (90% males) with a mean age of 48.3 years (SD = 5.6) were recruited. NLR ≥ 2.9 was associated with all causes mortality, as well as, PLR ≥ 126. NLR and PLR were predictors of OS, RFS, and LRD, while PNI did not emerge as a prognostic marker. According to the multivariate analysis, no HCC treatment was the only risk factor associated with risk of death. The areas under the ROC curves were 68.3 (95% confidence interval [CI], 54.5-82.1) for PLR and 66.3 (95% CI, 54.3-78.2) for NLR at 3 years; similar results were found at 5 years of follow-up.

CONCLUSIONS

Although, if examined singularly, NLR and PLR are prognostic factors for HCC recurrence and survival in HIV-infected patients, at the multivariate analysis, "no HCC treatment" remains the only independent risk factor associated with fatal outcome.

The prognostic value of prognostic nutritional index in hepatocellular carcinoma patients: A meta-analysis of observational studies

Background and aims

The clinical value of the prognostic nutritional index (PNI) in hepatocellular carcinoma (HCC) has been investigated in previous studies, but the results remain controversial. Here we present a meta-analysis to systematically review the association between PNI and HCC prognosis.

Method

PubMed, EMBASE, Web of Science databases were systematically searched to identify relevant studies. Data were abstracted independently by two reviewers. A meta-analysis was performed to determine the prognostic and clinic-pathological values of PNI in HCC patients. Odds ratios (ORs) and 95% confidence intervals (CIs) were extracted to estimate the association of PNI with survival and clinic-pathological characteristics, respectively.

Results

A total of eleven studies involving 3165 patients were analyzed. The pooled results indicated that low PNI is a significant predictor of poor 1-year, 3-year, 5-year OS (OR, 2.91, 4.05, 3.65; 95%CI, 2.30 to 3.70, 3.27 to 5.03,2.96–4.50; P = 0.14,0.22,0.11 respectively) and disease-free survival (DFS) (OR,2.35, 2.57, 2.75; 95%CI, 1.71 to 3.23, 1.89 to 3.49,2.01 to 3.75; P = 0.39,0.04,0.11, respectively). Moreover, PNI is significantly associated with serum AFP, tumor recurrence, tumor size and TNM stages in HCC patients. However, PNI is not significantly associated with tumor number and the incidence of cirrhosis in HCC patients.

Conclusions

PNI is an independent predictive indicator of survival and associated with serum AFP, tumor recurrence, tumor size and TNM stages in HCC patients.

Early postoperative controlling nutritional status (CONUT) score is associated with complication III-V after hepatectomy in hepatocellular carcinoma: A retrospective cohort study of 1,334 patients

Postoperative complication III-V is closely related with hepatectomy-related mortality for hepatocellular carcinoma (HCC) patients. The aim of the study was to investigate the relationship between CONUTS and postoperative complication III-V. 1334 HCC patients who underwent hepatectomy were divided into two groups: high CONUTS group (early postoperative CONUTS ≥ 8, n = 659) and low CONUTS group (early postoperative CONUTS < 8, n = 675). The characteristics and clinical outcomes were compared and analyzed. Risk factors for postoperative complication III-V were evaluated by univariate and multivariate analysis. early postoperative CONUTS showed a good prediction ability for postoperative complication III-V (AUROC = 0.653, P < 0.001), with the cut-off value of 8. The high CONUTS group had higher incidence of postoperative pulmonary complications (12.0% vs 7.9%, P = 0.011), bile leakage (2.6% vs 0.9%, P = 0.018), intra-abdominal hemorrhage (4.9% vs 1.6%, P = 0.001), postoperative liver failure Grade C (3.6% vs 1.0%, P = 0.002), complication III-V (15.6% vs 6.2%, P < 0.001), length of ICU stay > 48 hours (9.4% vs 4.1%, P < 0.001) and mortality in 90 days (2.6% vs 0.4%, P = 0.001), longer period of postoperative hospitalization (10 (8–13) vs 9 (7–11) days, P < 0.001). Multivariable analysis revealed that early postoperative CONUTS ≥ 8 (OR = 2.054, 95%CI = 1.371–3.078, P < 0.001) was independently associated with postoperative complication III-V. Early postoperative CONUTS ≥ 8 was identified as a novel risk factor for postoperative complication III-V, and should be further evaluated as a predictive marker for who are to undergo liver resection.

The Predictive Value of Staging Systems and Inflammation Scores for Patients with Combined Hepatocellular Cholangiocarcinoma After Surgical Resection: a Retrospective Study

BACKGROUND

Combined hepatocellular cholangiocarcinoma (cHCC-CC) is a rare form of primary liver tumor. A specific staging system for predicting survival in patients with cHCC-CC is not available. The aim of the present study was to evaluate the ability of staging systems and inflammation-based scores to predict overall survival (OS) and progression-free survival (PFS) of patients with cHCC-CC after surgical resection.

METHODS

The data from 99 patients with cHCC-CC after surgical resection from June 2000 and January 2017 were retrospectively collected. Patients were allocated into HCC (hepatocellular carcinoma)-dominant (IHD) group and ICC (intrahepatic cholangiocarcinoma)-dominant (IID) group based on radiological characteristics. Similarly, patients were also divided into HCC-dominant (PHD) group and ICC-dominant (PID) group based on pathological characteristics. Univariate and multivariate analyses were performed to identify variables associated with OS and PFS. The prognostic value of staging systems and inflammation-based scores were analyzed and compared using receiver operating characteristic (ROC) curves.

RESULTS

The 1-, 2-, and 3-year OS rates were 82.6, 66.3, and 59.6%, respectively. The 1-, 2-, and 3-year PFS rates were 52.2, 38.1, and 31.5%, respectively. Independent prognostic factors identified by multivariate analyses included HCC-TNM staging system and tumor diameter both for OS and PFS analyses. HCC-TNM staging system displayed higher area under ROC curve (AUC) values than the other staging systems or inflammation-based scores.

CONCLUSIONS

HCC-TNM staging system was able to adequately predict prognosis of patients with cHCC-CC after surgical resection, especially for patients with HCC-dominant characteristics in clinical practice.

Potential role of microRNA‑223‑3p in the tumorigenesis of hepatocellular carcinoma: A comprehensive study based on data mining and bioinformatics

The aims of the present study were to examine the potential role of microRNA‑233‑3p (miR)‑223‑3p in the tumorigenesis of hepatocellular carcinoma (HCC), and to investigate its diagnostic accuracy and potential molecular mechanisms. The expression data of miR‑223‑3p in HCC were obtained from the Gene Expression Omnibus (GEO). Data for the precursor miR‑223 were obtained from The Cancer Genome Atlas (TCGA). The diagnostic role of miR‑223‑3p was identified by the receiver operating curve (ROC), and the diagnostic value of miR‑223‑3p in HCC was calculated from qualified reports in the literature. In addition, associated data from the GEO, TCGA and qualified experiments were pooled for comprehensive meta‑analysis. Genes, which intersected between online prediction databases, natural language processing and differentially expressed genes from TCGA were regarded as potential targets of miR‑223‑3p in HCC. The Gene Ontology enrichment analysis and the Kyoto Encyclopedia of Genes and Genomes pathways of potential targets were performed using the Database for Annotation, Visualization and Integrated Discovery. The protein‑protein interactions were mapped using the Search Tool for the Retrieval of Interacting Genes. Among 15 qualified microarray data sets from GEO, seven showed that a significantly lower level of miR‑223‑3p was present in the HCC tissues, compared with that in non‑cancerous tissues (P<0.05). In addition, five GEO data sets revealed diagnostic values of miR‑223‑3p, with an area under the curve (AUC) of >0.80 (P<0.05). The diagnostic accuracy of the precursor miR‑223 in TCGA was also calculated (AUC=0.78, P<0.05). Similarly, the precursor miR‑223 showed a higher level of downregulation in HCC tissues, compared with that in healthy controls in TCGA (P<0.001). A summary ROC was also calculated as 0.89 (95% CI, 0.85‑0.91) in the meta‑analysis. A total of 72 potential targets were extracted, mainly involved in the terms 'microRNAs in cancer', 'ATP binding' and 'prostate cancer'. Five potential target genes were considered the hub genes of miR‑223‑3p in HCC, including checkpoint kinase 1, DNA methyltransferase 1, baculoviral IAP repeat containing 5, kinesin family member 23, and collagen, type I, α1. Based on TCGA, the hub genes were significantly upregulated in HCC (P<0.05). Collectively, these results showed that miR‑223‑3p may be crucial in HCC carcinogenesis showing high diagnostic accuracy, and may be mediated by several hub genes.

Inflammation scores predict the survival of patients with hepatocellular carcinoma who were treated with transarterial chemoembolization and recombinant human type-5 adenovirus H101

BACKGROUND

The systemic inflammatory response plays an important role in cancer development and progression. An original inflammation-based staging system for predicting survival in patients undergoing transarterial chemoembolization (TACE) combined with recombinant human type-5 adenovirus H101 is not available. This study aimed to validate the prognostic value of inflammation scores for patients with hepatocellular carcinoma (HCC) who were treated with TACE combined with H101.

METHODS

The data from 216 patients with HCC who underwent TACE combined with H101 from January 2007 to July 2015 were retrospectively collected, and the association of the inflammation scores with overall survival (OS) was analyzed. Univariate and multivariate analyses were performed to identify variables associated with OS. The prognostic value of the inflammation scores, including the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), neutrophil/ platelet-to-lymphocyte ratio (NLR-PLR), modified Glasgow Prognostic Score (mGPS), prognostic nutritional index (PNI), prognostic index (PI), tumor-node-metastasis (TNM), Barcelona Clinic Liver Cancer (BCLC) and Cancer of the Liver Italian Program (CLIP) staging systems were analyzed and compared using the areas under the receiver operating characteristic curves (AUROCs).

RESULTS

The estimated 1-, 2-, and 3-year OS rates were 61.3%, 44.2%, and 40.5% for the entire study cohort, respectively; the median OS was 17 months. According to the multivariate Cox proportional hazards model, the pretreatment NLR, tumor diameter and pretreatment alpha-fetoprotein (AFP) levels were independent predictors of OS. The CLIP score had superior discriminative abilities compared with other staging systems, and the NLR-PLR score consistently displayed a higher AUROC value than the other inflammation-based prognostic scores. The combination of the NLR-PLR and CLIP scores exhibited a superior prognostic ability for OS compared to the NLR-PLR or CLIP scores alone.

CONCLUSIONS

The NLR-PLR score is a more powerful predictive system than the other inflammation-based scores for patients with HCC who were treated with TACE and H101. The predictive ability may be improved by utilizing a combination of the NLR-PLR and CLIP scores.
