Preoperative Myosteatosis and Prognostic Nutritional Index Predict Survival in Older Patients With Resected Biliary Tract Cancer.

Background/Aim: Sarcopenia accompanied by systemic inflammation is associated with poor prognosis in patients with cancer. This study evaluated the prognostic significance of sarcopenia (myopenia and myosteatosis) and systemic inflammatory markers in older patients (aged ≥80 years) with resected biliary tract cancer. Patients and Methods: Patients who underwent resection for biliary tract cancer between July 2010 and January 2023 at the NHO Fukuyama Medical Center were retrospectively reviewed. Preoperative computed tomography measured myopenia and myosteatosis, using the psoas muscle index and modified intramuscular adipose tissue content. Associations between clinicopathological characteristics, inflammation-based prognostic scores, and overall survival were analyzed using Cox proportional hazards models. Results: Univariate analysis revealed low C-reactive protein-to-albumin ratio (<0.125), low prognostic nutritional index (<42), low modified intramuscular adipose tissue content, higher T-stage (T3-4), lymph node metastasis, and postoperative complications associated with worse overall survival in older patients (aged ≥ 80 years) with resected biliary tract cancer (n=48). Multivariate analysis identified low prognostic nutritional index (<42) (p=0.007), low modified intramuscular adipose tissue content (p=0.015), higher T-stage (T3-4) (p<0.001), lymph node metastasis (p=0.001), and postoperative complications (p=0.017) as independent predictors of overall survival. Conclusion: Preoperative myosteatosis and low prognostic nutritional index are independent prognostic factors for overall survival in older patients (aged ≥80 years) with resected biliary tract cancer. These factors may be useful for risk stratification and clinical decision-making. Early interventions, such as nutritional support and physical exercise, may improve outcomes after resection of biliary tract cancer.

Prognostic Significance of Sarcopenia and Systemic Inflammatory Markers in Biliary Tract Cancer: A Retrospective Cohort Study.

PURPOSE: To evaluate the prognostic significance of sarcopenia and systemic inflammatory markers in patients with surgically resected biliary tract cancer (BTC). METHODS: Between July 2010 and December 2022, 146 patients were recruited. Sarcopenia was assessed using the psoas muscle index. Preoperative inflammatory markers were used to calculate the prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio. Cox regression analysis was performed to determine prognostic factors for overall survival (OS) and recurrence-free survival (RFS). P < 0.05 was considered statistically significant. RESULTS: Sixty-four patients had sarcopenia. Sarcopenia was associated with body mass index (< 22 kg/m2), lymph node metastasis, and low PNI (< 42). R1/R2 resection (P = 0.02), sarcopenia (P < 0.001), lymph node metastasis (P = 0.007), intrahepatic cholangiocarcinoma (P < 0.001), and low PNI (P = 0.01) were independent predictors of OS, while male sex (P = 0.04), R1/R2 resection (P < 0.001), lymph node metastasis (P = 0.005), intrahepatic cholangiocarcinoma (P < 0.001), tumor differentiation (other than well; P = 0.003), and low PNI (P = 0.03) were independent predictors of RFS. Patients were stratified into no sarcopenia and high PNI (≥ 42; A), sarcopenia or low PNI (B), and sarcopenia and low PNI (C) groups. Group C had worse OS than the other two groups (P < 0.001 and P = 0.02, respectively). CONCLUSION: Sarcopenia is associated with the PNI. Sarcopenia and the PNI are independent prognostic factors among patients with resected BTC. Sarcopenia may have better prognostic value when combined with the PNI.

Predictive values of sarcopenia and systemic inflammation-based markers in advanced hepatocellular carcinoma after hepatectomy.

BACKGROUND: Sarcopenia accompanied by systemic inflammation is associated with poor prognosis in patients with advanced hepatocellular carcinoma (HCC). However, the effect of sarcopenia combined with systemic inflammation on the prognosis of patients with advanced HCC who underwent hepatectomy is unclear. This study aimed to evaluate the effect of sarcopenia and inflammation on the prognosis of patients with advanced HCC. METHODS: This retrospective study included 151 patients recruited between July 2010 and December 2022. We defined advanced HCC as that presenting with vascular invasion or tumor size ≥2 cm or multiple tumors. Sarcopenia was assessed using the psoas muscle index. Preoperative inflammatory markers were used by calculating the prognostic nutritional index, albumin-globulin ratio (AGR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio. Cox regression analysis was performed to determine the prognostic factors for overall survival. RESULTS: Of 151 patients, sarcopenia occurred in 84 (55.6 %). Sarcopenia was significantly associated with male sex, older age, body mass index (<25 kg/m2), and a higher NLR. In the multivariate analysis, AGR <1.25 (hazard ratio [HR], 2.504; 95% confidence interval [CI]: 1.325-4.820; p < 0.05); alpha-fetoprotein levels ≥25 ng/mL (HR, 1.891; 95% CI: 1.016-3.480; p = 0.04); and sarcopenia (HR, 1.908; 95% CI: 1.009-3.776; p < 0.05) were independent predictors of overall survival. The sarcopenia and low AGR groups had significantly worse overall survival than either the non-sarcopenia and high AGR or sarcopenia and low AGR groups. CONCLUSION: Sarcopenia and AGR are independent prognostic factors in patients with advanced HCC. Thus, sarcopenia may achieve a better prognostic value when combined with AGR.

The combination of the low immunohistochemical expression of peroxiredoxin 4 and perilipin 2 predicts longer survival in pancreatic ductal adenocarcinoma with peroxiredoxin 4 possibly playing a main role.

Pancreatic ductal adenocarcinoma (PDAC) is a fatal disease with poor prognosis. Therefore, indicators that can be used for the early prediction of the prognosis of PDAC are needed. Peroxiredoxin (PRDX) 4 is a secretion-type antioxidant enzyme located in the cytoplasmic endoplasmic reticulum. Recent studies have reported that it is closely related to the development and prognosis of many types of cancer. Perilipin (PLIN) 2 is a lipid droplet coating protein. The high expression of PLIN2 is known to be an indicator of some types of cancer and oxidative stress management. It is highly suggestive of the interplay between PRDX4 and PLIN2 to some degree. In this study, we collected 101 patients' clinical data and paraffin-embedded specimens with PDAC and analyzed them with immunohistochemical staining of PRDX4 and PLIN2. We found that the low expression of PRDX4 predicts longer survival and a better clinical condition in PDAC patients. Moreover, when the low expression of PRDX4 is combined with the low expression of PLIN2, the 3-year survival is significantly improved. Univariate and multivariate Cox proportional hazard analyses showed that the PRDX4 expression in PDAC was an independent prognostic factor for survival. Taken together, between PRDX4 and PLIN2, PRDX4 plays a main role in prognosis and has the potential to become a clinical prognostic indicator of PDAC.

Synchronous Double Primary Combined Hepatocellular-cholangiocarcinoma and Cholangiolocarcinoma in a Cirrhotic Liver.

Both combined hepatocellular-cholangiocarcinoma (cHCC-CCA) and cholangiolocarcinoma are rare primary liver cancers. cHCC-CCA is believed to originate from transformed hepatocellular carcinoma or liver stem/progenitor cells. Cholangiolocarcinoma is characterized by ductular reaction-like anastomosing cords and glands resembling cholangioles or canals containing hepatocellular carcinoma components and adenocarcinoma cells. According to the 2019 revision of the World Health Organization criteria, a subtype with stem cell features as a subclassification of cHCC-CCA was abolished for lack of conclusive evidence of the stem cell origin theory. That led to the classification of cholangiolocarcinoma with hepatocytic differentiation as cHCC-CCA. Consequently, cholangiolocarcinoma without hepatocytic differentiation is classified as a subtype of small-duct cholangiocarcinoma and is assumed to originate from the bile duct. Herein, we report the first case of double primary cHCC-CCA and cholangiolocarcinoma without hepatocytic differentiation in different hepatic segments of a cirrhotic liver. We believe this case supports the validity of the new World Health Organization criteria because the pathological finding of cHCC-CCA in this case shows the transformation of hepatocellular carcinoma to cholangiocarcinoma. Furthermore, this case may demonstrate that immature ductular cell stemness and mature hepatocyte cell stemness in hepatocarcinogenesis can coexist in the same environment. The results provide valuable insights into the mechanisms of growth, differentiation, and regulation of liver cancers.

Preoperative C-reactive protein-to-albumin ratio as a prognostic factor in biliary tract cancer: A systematic review and meta-analysis.

BACKGROUND: The preoperative C-reactive protein-to-albumin ratio is a novel inflammation-based prognostic marker in various cancers. However, its prognostic role in biliary tract cancer is unknown. We conducted a systematic review and meta-analysis to evaluate the prognostic value of preoperative C-reactive protein-to-albumin ratio in biliary tract cancer. METHODS: A systematic search of the literature for studies evaluating the prognostic value of C-reactive protein-to-albumin ratio in patients undergoing surgery for biliary tract cancer was conducted, and a random effects meta-analysis of overall survival and recurrence-free survival was performed. RESULTS: Nine studies with 1292 participants were included. The preoperative C-reactive protein-to-albumin ratio negatively correlated with overall survival (hazard ratio, 2.44 [95% confidence interval: 1.98-2.90]; P < .001) and recurrence-free survival (hazard ratio, 2.73 [95% confidence interval: 2.01-3.70]; P < .001). Subgroup analysis showed that an elevated preoperative C-reactive protein-to-albumin ratio predicted poor overall survival, regardless of the cutoff value, sample size, histological type, and treatment. CONCLUSION: An elevated preoperative C-reactive protein-to-albumin ratio is significantly associated with poor prognosis in patients undergoing surgery for biliary tract cancer. The C-reactive protein-to-albumin ratio may be an independent prognostic biomarker for overall survival and recurrence-free survival in patients undergoing surgery for biliary tract cancer.

Clinical implications and optimal extent of lymphadenectomy for intrahepatic cholangiocarcinoma: A multicenter analysis of the therapeutic index.

Aims: Lymph node metastases (LNM) are associated with lethal prognosis in intrahepatic cholangiocarcinoma (ICC). Lymphadenectomy is crucial for accurate staging and hopes of possible oncological treatment. However, the therapeutic implications and optimal extent of lymphadenectomy remain contentious. Methods: To clarify the prognostic value and optimal extent of lymphadenectomy, the therapeutic index (TI) for each lymph node was analyzed for 279 cases that had undergone lymphadenectomy in a multi-institutional database. Tumor localization was divided into hilar lesions (n = 130), right peripheral lesions (n = 60), and left peripheral lesions (n = 89). In addition, the lymph node station was classified as Level 1 (LV1: hepatoduodenal ligament node), Level 2 (LV2: postpancreatic or common hepatic artery nodes), or Level 3 (LV3: gastrocardiac, left gastric artery, or celiac artery nodes). Results: Lymph node metastases were confirmed in 109 patients (39%). Five-y survival rates were 45.3% for N0 disease, 27.1% for LV1-LNM, 22.9% for LV2-LNM, and 7.3% for LV3-LNM (P < 0.001). LV3-LNM were the most frequent and earliest recurrence outcome, including multisite recurrence, followed by LV2, LV1, and N0 disease. The 5-year TI (5year-TI) for lymphadenectomy was 7.2 for LV1, 5.5 for LV2, and 1.9 for LV3. Regarding tumor location, hilar lesions showed 5-year TI >5.0 in LV1 and LV2, whereas bilateral peripheral lesions showed 5-year TI > 5.0 in LV1. Conclusion: The implications and extent of lymphadenectomy for ICC appear to rely on tumor location. In the peripheral type, the benefit of lymphadenectomy would be limited and dissection beyond LV1 should be avoided, while in the hilar type, lymphadenectomy up to LV2 could be recommended.

C-reactive Protein-to-Albumin Ratio Predicts Conversion from Laparoscopic to Open Cholecystectomy in Acute Cholecystitis.

BACKGROUND/AIM: The aim of this study was to identify predictors of conversion from laparoscopic to open cholecystectomy, and to determine whether pre-operative C-reactive protein-to-albumin ratio (CAR) can predict conversion from laparoscopic to open cholecystectomy, in patients with acute cholecystitis diagnosed according to the Tokyo Guidelines 2018. PATIENTS AND METHODS: We retrospectively analysed 231 patients who underwent laparoscopic cholecystectomy for acute cholecystitis between January 2012 and March 2022. Two hundred and fifteen (93.1%) patients were included in the laparoscopic cholecystectomy group; sixteen (6.9%) patients were included in the conversion from laparoscopic to open cholecystectomy group. RESULTS: In univariate analysis, significant predictors of conversion from laparoscopic to open cholecystectomy included the interval between symptom onset and surgery (>72 h), C-reactive protein (≥15.0 mg/l) and albumin (<3.5 mg/l) levels, pre-operative CAR (≥5.54), gallbladder wall thickness (≥5 mm), pericholecystic fluid collection, and pericholecystic fat hyperdensity. In multivariate analysis, elevated pre-operative CAR (≥5.54) and the interval between symptom onset and surgery (>72 h) were independent predictors of conversion from laparoscopic to open cholecystectomy. CONCLUSION: Pre-operative CAR as a predictor of conversion from laparoscopic to open cholecystectomy may be useful for pre-operative risk assessment and treatment planning.

Lymphocyte-to-C-Reactive Protein Ratio Predicts Prognosis in Patients With Colorectal Liver Metastases Post-hepatic Resection: A Retrospective Study.

BACKGROUND/AIM: Preoperative systemic inflammation has been reported to predict survival in patients with various cancer types. In patients with colorectal liver metastasis (CRLM), the prognosis is poor despite therapeutic advances in the field. Here, we aimed to evaluate the prognostic role of the lymphocyte-to-C-reactive protein (CRP) ratio (LCR) in patients with CRLM after hepatic resection. PATIENTS AND METHODS: This retrospective study included 104 patients who underwent hepatic resection for CRLM between October 2010 and 2021 at the National Hospital Organization Fukuyama Medical Center, Hiroshima, Japan. The association between clinicopathological variables, including various inflammatory biomarkers [LCR, platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), CRP-to-albumin ratio (CAR), and prognostic nutritional index (PNI)], and overall survival of the patients was investigated using univariate and multivariate analyses. RESULTS: The optimal cut-off values for each biomarker by receiver-operating characteristic analysis were as follows: LCR: 12,720; PLR: 150; NLR: 4; CAR: 0.023; and PNI: 44.8. The 1-, 3-, and 5-year overall survival rates were 97.0%, 71.3%, and 56.8%, respectively. On univariate analysis, LCR<12, 720, PLR<0.14, body mass index <24 kg/m2, carbohydrate antigen 19-9 ≥37 U/ml, multiple tumours, and largest hepatic tumour ≥5 cm were significant factors predictive of poorer survival. The multivariate analysis revealed that LCR<12, 720 (hazard ratio=2.156, 95% confidence interval=1.060-4.509, p=0.034) and multiple tumours (HR=2.336, 95% CI=1.125-4.925, p=0.023) were independent predictors of poor overall survival. CONCLUSION: LCR may be an independent prognostic predictor in patients after hepatic resection for CRLM. Therefore, the assessment of LCR as a biomarker may help in treatment planning.

Preoperative lymphocyte-to-C-reactive protein ratio predicts hepatocellular carcinoma recurrence after surgery.

Purpose: This study was performed to determine the prognostic value of lymphocyte-to-CRP ratio after curative resection for hepatocellular carcinoma. Methods: Between July 2010 and October 2021, 173 consecutive patients (144 male, 29 female) who underwent surgical resection for pathologically confirmed hepatocellular carcinoma were included in this retrospective study. Cox regression analysis was used to evaluate the relationship between clinicopathological characteristics and recurrence-free survival (RFS) and overall survival (OS). A P-value of <0.05 was considered statistically significant. Results: The patients (mean age, 71 years) were stratified into high (≥9,500, n = 108) and low (<9,500, n = 65) lymphocyte-to-CRP ratio groups. The low lymphocyte-to-CRP ratio group had significantly worse RFS and OS. Low lymphocyte-to-CRP ratio (hazard ratio [HR], 1.865; 95% confidence interval [CI], 1.176-2.960; P = 0.008), multiple tumors (HR, 3.333; 95% CI, 2.042-5.343; P < 0.001), and microvascular invasion (HR, 1.934; 95% CI, 1.178-3.184; P = 0.009) were independently associated with RFS, whereas low albumin-to-globulin ratio (HR, 2.270; 95% CI, 1.074-4.868; P = 0.032), α-FP of ≥25 ng/mL (HR, 2.187; 95% CI, 1.115-4.259; P = 0.023), and poor tumor differentiation (HR, 2.781; 95% CI, 1.041-6.692; P = 0.042) were independently associated with OS. Lymphocyte-to-CRP ratio had a higher area under the curve (0.635) than other inflammation-based markers (0.51-0.63). Conclusion: Lymphocyte-to-CRP ratio is superior to other inflammation-based markers as a predictor of RFS in patients with surgically resected hepatocellular carcinoma.

C-reactive protein to albumin ratio predicts difficult laparoscopic cholecystectomy in patients with acute cholecystitis diagnosed according to the Tokyo Guidelines 2018.

INTRODUCTION: Difficult laparoscopic cholecystectomy (DLC) may increase the risk of complications and extend the duration of hospitalization. The aims of this study were to evaluate the predictive value of C-reactive protein/albumin ratio (CAR) for DLC in patients with acute cholecystitis (AC) diagnosed according to the Tokyo Guidelines 2018 and to develop a preoperative predictive model for DLC. METHODS: We retrospectively analyzed 205 patients who had laparoscopic cholecystectomy for AC between January 2012 and December 2020. We defined DLC cases as having one of the following factors: blood loss ≥50 mL, operative time ≥150 minutes, or conversion to open surgery. We classified the remaining cases into the non-DLC group. RESULTS: Overall, 127 (62.0%) and 78 (38.0%) patients were grouped into the DLC and non-DLC groups, respectively. Patients in the DLC group had: higher severity grade, which was assessed using the Tokyo Guidelines 2018; higher incidence of postoperative complications; and more hospitalization days than those in the non-DLC group. Multivariate analysis revealed that male, CAR (≥3.20), and pericholecystic fat hyperdensity on computed tomography (CT) were independent predictors of DLC. We developed a predictive scoring system for DLC based on these three factors (cutoff value, 2.0; area under the curve, 0.75; sensitivity, 71.7%; and specificity, 70.5%). CONCLUSION: CAR could predict DLC independently in AC patients. We identified male gender, CAR, and pericholecystic fat hyperdensity on CT as predictive factors for DLC and established a preoperative prediction system based on these three factors.

Impact of lymph node dissection on clinical outcomes of intrahepatic cholangiocarcinoma: Inverse probability of treatment weighting with survival analysis.

BACKGROUND: Lymph node metastasis (LNM) has been established as a critical risk factor for prognosis in intrahepatic cholangiocarcinoma (ICC). The clinical implications of lymph node dissection (LND) have been debated. This study aimed to clarify the prognostic impact of LND by multicenter retrospective analysis. METHODS: A total of 310 ICC patients who had undergone curative resection between 2000 and 2016 were retrospectively analyzed. The prognostic impact of LND was estimated under an inverse probability of treatment weighting (IPTW) approach using propensity scores. RESULTS: LND was performed for 224 patients (72%), with LNM pathologically confirmed in 90 patients (40%). Prognosis was poorer for patients with LNM (median survival, 16.9 months) than for those without (57.2 months; P < .0001). One-, 3-, and 5-year overall survival rates (OS) were comparable among LND+ (81.6%, 48.0%, and 37.5%, respectively) and LND- groups (81.6%, 55.4%, and 44.6%, respectively). However, advanced tumor, as characterized by larger tumor, multinodular lesions, and serosal invasion, was significantly more frequent in the LND+ group than in the LND- group. After IPTW adjusting for imbalances, 1-, 3-, and 5-year OS were better in the LND+ group (83.5%, 52.2%, and 42.8%, respectively) than in the LND- group (71.9%, 32.4%, and 23.4%, respectively; P = .046). LND thus showed significant prognostic impact (hazard ratio = 0.58, 95%CI = |0.39|-|0.84|, P = .005), especially in hilar ICC. However, peripheral ICC displayed no therapeutic benefit from LND. CONCLUSIONS: LND could have a significant role to play in improving oncologic outcomes. Therapeutic LND should be implemented on the basis of tumor location and tumor advancement.

[Laparoscopic Surgery for Gastric Gastrointestinal Stromal Tumors].

Gastric gastrointestinal stromal tumors(GISTs)are rarely accompanied by lymph node metastasis; therefore, laparoscopic partial gastrectomy is feasible for managing GISTs. Between 2005 and 2022, 60 patients underwent open or laparoscopic surgery for preoperatively suspected or histopathologically confirmed GISTs. Tumors were detected in the upper, mid, and lower stomach in 38, 18, and 4 patients, respectively. Intraluminal tumors or those with a mixed tumor growth pattern were identified in 42 patients, whereas tumors with an extraluminal growth pattern were noted in 18 patients. Open and laparoscopic surgery was performed in 28 and 32 patients, respectively. The adaptation for laparoscopic surgery was less than 5 cm in size. The laparoscopic approaches were as follows: conventional wedge resection in 19 patients, transillumination and serosal dissection method in 3, laparoscopic and endoscopic cooperative surgery in 8, and gastrectomy in 2 patients. Compared with the open surgery group, the laparoscopic surgery group presented a significant reduction in operation time, estimated blood loss, tumor size, and length of postoperative hospitalization. Based on the modified-Fletcher clinicopathological risk classification, 49, 6, and 5 patients were categorized into the low- or very low-, mid-, and high-risk groups, respectively. Recurrence was only observed in the open surgery group. The 10-year survival rates were 100% in both groups. The 5-year recurrence-free survival rates were 100 and 87% in the laparoscopic and open surgery groups, respectively. The aforementioned laparoscopic approaches were associated with favorable surgical outcomes.

A combined prediction model for biliary tract cancer using the prognostic nutritional index and pathological findings: a single-center retrospective study.

BACKGROUND: The prognostic nutritional index, a marker of nutritional status and systemic inflammation, is a known biomarker for various cancers. However, few studies have evaluated the predictive value of the prognostic nutritional index in patients with biliary tract cancer. Therefore, we investigated the prognostic significance of the prognostic nutritional index, and developed a risk-stratification system to identify prognostic factors in patients with biliary tract cancer. METHODS: Between July 2010 and March 2021, 117 patients with biliary tract cancer were recruited to this single-center, retrospective study. The relationship between clinicopathological variables, including the prognostic nutritional index, and overall survival was analyzed using univariate and multivariate analyses. A P < 0.05 was considered statistically significant. RESULTS: The median age was 75 (range 38-92) years. Thirty patients had intrahepatic cholangiocarcinoma; 29, gallbladder carcinoma; 27, distal cholangiocarcinoma; 17, ampullary carcinoma; and 13, perihilar cholangiocarcinoma. Curative (R0) resection was achieved in 99 patients. In univariate analysis, the prognostic nutritional index (< 42), lymph node metastasis, carbohydrate antigen 19-9 level (> 20 U/mL), preoperative cholangitis, tumor differentiation, operation time (≥ 360 min), and R1-2 resection were significant risk factors for overall survival. The prognostic nutritional index (P = 0.027), lymph node metastasis (P = 0.040), and tumor differentiation (P = 0.006) were independent prognostic factors in multivariate analysis. A combined score of the prognostic nutritional index and pathological findings outperformed each marker alone, in terms of discriminatory power. CONCLUSIONS: The prognostic nutritional index, lymph node metastasis, and tumor differentiation were independent prognostic factors after surgical resection in patients with biliary tract cancer. A combined prediction model using the prognostic nutritional index and pathological findings accurately predicted prognosis, and can be used as a novel prognostic factor in patients with biliary tract cancer.

Preoperative Albumin-to-Globulin Ratio Predicts Prognosis in Hepatocellular Carcinoma: A Cohort Study Including Non-Hepatitis Virus-Infected Patients.

INTRODUCTION: We evaluated the prognostic significance of the preoperative albumin-to-globulin ratio (AGR) in patients with hepatocellular carcinoma (HCC) with various liver etiologies. METHODS: We retrospectively analyzed 157 patients with HCC between July 2010 and February 2021. The relationship between clinicopathological variables was investigated using univariate and multivariate analyses. Statistical significance was set at p < 0.05. RESULTS: The mean overall survival (OS) was 24.5 months. The 1-, 3-, and 5-year OS rates were 90.4%, 81.2%, and 68.7%, respectively. Patients were classified into 2 groups: AGR <1.16 (low-AGR group; n = 43) and AGR ≥1.16 (high-AGR group; n = 114). In univariate analysis, OS was significantly reduced in patients with a low AGR (AGR <1.16), an alpha-fetoprotein level ≥25 ng/mL, a tumor size ≥3.5 cm, microvascular invasion, and poor tumor differentiation. In multivariate analysis, a low AGR (hazard ratio [95% confidence interval]) (2.394 [1.092-5.213]; p = 0.030) and microvascular invasion (2.268 [1.019-5.169]; p = 0.045) were independent predictors of OS. DISCUSSION/CONCLUSION: A low AGR was significantly associated with poor OS in patients with HCC, regardless of liver etiology. This may assist in treatment stratification and better management of patients with HCC.

Low dose red yeast rice with monacolin K lowers LDL cholesterol and blood pressure in Japanese with mild dyslipidemia: A multicenter, randomized trial.

BACKGROUND AND OBJECTIVES: Red yeast rice contains monacolin K, an inhibitor of cholesterol synthesis, and gamma-aminobutyric acid, a neurotransmitter. The daily dose of red yeast rice and monacolin K in previous studies was relatively high; therefore, there were safety concerns. We aimed to examine the effects of low daily dose red yeast rice on arteriosclerosis in patients with mild dyslipidemia. METHODS AND STUDY DESIGN: Eighteen patients without known cardiovascular disease and unsatisfactory low-density lipoprotein cholesterol (3.96±0.19 mmol/L) controlled only by diet therapy were randomly allocated to receive low dose red yeast rice (200 mg/day) containing 2 mg monacolin K or diet therapy alone for 8 weeks. The primary outcome was the absolute change in low-density lipoprotein cholesterol. Secondary outcomes included total cholesterol, apolipoprotein B, and blood pressure. RESULTS: Low-density lipoprotein cholesterol decreased significantly in the red yeast rice group than in the diet therapy group (median [interquartile range]: control -0.20 [-0.62, 1.19] mmol/L vs. red yeast rice -0.96 [-1.05, -0.34] mmol/L, p=0.030). The red yeast rice group also exhibited significant decreases in total cholesterol, apolipoprotein B, and blood pressure. No severe treatment-related adverse effects on muscles, liver, or renal function were observed. CONCLUSIONS: We found that patients in the red yeast rice group exhibited significant reductions in lowdensity lipoprotein cholesterol, total cholesterol, apolipoprotein B, and blood pressure without any recognised adverse effect. This suggests that low daily dose red yeast rice could reduce cardiovascular risk in patients with dyslipidemia.

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.

Comparison of Inflammation-based Prognostic Scores in Patients With Biliary Tract Cancer After Surgical Resection.

BACKGROUND/AIM: Inflammation-based prognostic scores are proven prognostic biomarkers in various cancers. This study aimed to identify a useful prognostic score for patients with biliary tract cancer (BTC) after surgical resection. PATIENTS AND METHODS: This retrospective study recruited 115 patients with BTC during 2010-2020. The relationship between clinicopathological variables, including various prognostic scores and overall survival (OS), was investigated using univariate and multivariate analyses. RESULTS: BTC included 58 cholangiocarcinoma, 29 gallbladder carcinoma, 16 ampullary carcinoma, and 12 perihilar cholangiocarcinoma cases. A significant difference was detected in OS of patients with a Japanese modified Glasgow prognostic score (JmGPS) 0 (n=62) and JmGPS 1 or 2 (high JmGPS) (n=53). In the multivariate analysis, tumour differentiation (p=0.014) and a high JmGPS (p=0.047) were independent prognostic factors. CONCLUSION: The high JmGPS was an independent prognostic predictor after surgical resection and was superior to other prognostic scores.

Prognostic Utility of the Glasgow Prognostic Score for the Long-Term Outcomes After Liver Resection for Intrahepatic Cholangiocarcinoma: A Multi-institutional Study.

OBJECTIVE: The usefulness of the modified Glasgow prognostic score (GPS) as a prognostic tool remains unclear for patients undergoing curative surgery for intrahepatic cholangiocarcinoma (ICC). Therefore, this study investigated the prognostic usefulness of the GPS for patients who underwent ICC surgery. METHOD: All ICC patients who had a curative-intent hepatectomy at 17 institutions between 2000 and 2016 were included. The correlation was assessed between the preoperative GPS and the baseline characteristics of the patients, histopathological parameters, surgical parameters, and the postresection overall survival (OS). RESULT: There were 273 patients who met the eligibility criteria between the years 2000 and 2016. The postoperative OS rates at 1, 3, and 5 years were 83.8%, 56.3%, and 41.5%, respectively (median OS, 47.7 months). A multivariate analysis revealed the factors that were associated with a worse OS, which included an increased GPS (hazard ratio = 1.62; 95% confidence interval [CI]: 1.01-2.53; P = 0.03), an elevated carcinoembryonic antigen level (hazard ratio = 1.60; 95% CI: 1.06-2.41; P = 0.02), an elevated carbohydrate antigen 19-9 level (hazard ratio = 1.55; 95% CI: 1.05-2.30; P = 0.03), undifferentiated carcinoma (hazard ratio = 2.41; 95% CI: 1.56-3.67; P < 0.01), and positive metastasis to the lymph nodes (hazard ratio = 2.54; 95% CI: 1.76-3.67; P < 0.01). In ICC patients after a hepatectomy, an elevated GPS was associated with poorer OS, even if the tumour factors that affected GPS were eliminated by propensity-score matching. CONCLUSION: Preoperative GPS can be useful to predict the postoperative outcomes of ICC patients. Therefore, this relatively simple and inexpensive scoring system can be utilized to further refine patient stratification as well as to predict survival.
