Combination of sarcopenia and systemic inflammation-based markers for predicting the prognosis of patients undergoing pancreaticoduodenectomy for pancreatic cancer.

BACKGROUND: This study aimed to evaluate the effects of sarcopenia and inflammation on the prognosis of patients with pancreatic cancer after pancreaticoduodenectomy. METHODS: Eighty patients who had undergone pancreaticoduodenectomy for pancreatic cancer between July 2010 and December 2023 were included in this study. The psoas muscle index was used to assess sarcopenia. The C-reactive protein-to-albumin ratio, prognostic nutritional index, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio were used to calculate the preoperative inflammatory marker levels. The prognostic factors for overall survival were determined using Cox regression analysis. RESULTS: Twenty-four patients were diagnosed with sarcopenia. Sarcopenia showed a significant association with advanced tumor stage. Univariate analysis revealed a significant reduction in overall survival in patients with a prognostic nutritional index of <45, C-reactive protein-to-albumin ratio of ≥0.047, cancer antigen 19-9 levels of ≥130 U/mL, sarcopenia, lymph node metastasis, and vascular invasion. Multivariate analysis revealed that a C-reactive protein-to-albumin ratio of ≥0.047 (hazards ratio, 3.383; 95% confidence interval: 1.384-8.689; p< 0.001), cancer antigen 19-9 levels of ≥130 U/mL (hazards ratio, 2.720; 95% confidence interval: 1.291-6.060; p = 0.008), sarcopenia (hazards ratio, 3.256; 95% confidence interval: 1.535-7.072; p = 0.002) and vascular invasion (hazards ratio, 2.092; 95% confidence interval: 1.057-4.170; p = 0.034) were independent predictors of overall survival. Overall survival in the sarcopenia and high C-reactive protein-to-albumin ratio groups was significantly poorer than that in the non-sarcopenia and low C-reactive protein-to-albumin ratio and sarcopenia or high C-reactive protein-to-albumin ratio groups. CONCLUSION: Sarcopenia and a high C-reactive protein-to-albumin ratio are independent prognostic factors in patients with pancreatic cancer after pancreaticoduodenectomy. Thus, sarcopenia may have a better prognostic value when combined with the C-reactive protein-to-albumin ratio.

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.

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.

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.

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.

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.

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.

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.

Nutritional assessment and surgical outcomes in very elderly patients undergoing pancreaticoduodenectomy: a retrospective study.

PURPOSE: To evaluate and compare the nutritional factors and clinical outcomes of pancreaticoduodenectomy between elderly and non-elderly patients. METHODS: This retrospective study evaluated 122 consecutive patients who underwent pancreaticoduodenectomy from April 2008 to April 2020. Preoperative and postoperative nutritional factors (prognostic nutritional index), complication rates, and survival rates were compared between the elderly (≥ 80 years) and non-elderly (< 80 years) patient groups. Changes in nutrition markers were evaluated before surgery to 1 year after surgery. RESULTS: A total of 20 elderly patients (16.4%) and 102 non-elderly patients (83.6%) underwent pancreaticoduodenectomy. Elderly patients had a significantly lower preoperative prognostic nutritional index than did non-elderly patients. At 3 months postoperatively, elderly patients had a lower albumin level and prognostic nutritional index. The median length of hospital stay was significantly longer (39.9 vs. 27 days, P = 0.004), the rate of death due to other diseases was higher, and the overall survival rate was significantly lower (1-/3-/5 year overall survival rates: 78.1%/26.7%/13.3% vs. 87.1%/54.4%/46.7%; log-rank test, P = 0.003) in the elderly group than in the non-elderly group. CONCLUSIONS: The results suggest that careful patient selection and optimal perioperative care are necessary to determine whether pancreaticoduodenectomy is indicated for elderly patients.

Solitary Cardiac Metastasis of Hepatocellular Carcinoma.

Cardiac metastasis originating from hepatocellular carcinoma (HCC) is a rare condition with a poor prognosis. No therapeutic standards for cardiac metastasis originating from HCC have been established. At 19 months after a curative hepatectomy, a 64-year-old Japanese hepatitis B virus-positive male patient experienced solitary cardiac metastasis originating from HCC. The cardiac tumor was discovered in the right ventricle. The patient received three courses of radiotherapy and chemotherapy and survived > 3 years after the initial diagnosis of cardiac metastasis. His case demonstrates that radiotherapy combined with chemotherapy can be an effective treatment for cardiac metastasis.

The Late Phase/Early Phase Ratio of Pancreatic CT Values as a Novel Predictor of Pancreatic Fistula after Distal Pancreatectomy.

Post-operative pancreatic fistula (POPF) remains the most common complication after distal pancreatectomy (DP). In this retrospective study, we reviewed the data from patients who underwent DP between 2008 and 2019 in our institute to determine whether the late phase/early phase ratio (L/E ratio) by preoperative computed tomography (CT) scan in the pancreas could predict POPF occurrence after DP. We examined the relationship between preoperative or intraoperative factors and the occurrence of POPF after DP using statistical methods in 23 males and 21 females with a mean age of 73. The mean L/E ratio was significantly lower in the POPF group than the non-POPF group (p=0.035). The L/E ratio had moderate diagnostic accuracy, with a calculated optimal cutoff value of 0.77. In univariate analysis, a significant association was noted between POPF and stump thickness ≥ 16.9, body mass index ≥ 27.5, and L/E ratio ≤ 0.77. In the multivariate analysis, the L/E ratio (odds ratio, 5.96; p=0.036) was an independent risk factor for POPF. Our findings suggest that the pancreatic L/E ratio may predict the occurrence of POPF after DP. This measure may be useful in preoperative risk stratification, patient counseling, and perioperative patient management, improving clinical outcomes after DP.

Preoperative predictive factors of pancreatic fistula after pancreaticoduodenectomy: usefulness of the CONUT score.

PURPOSE: Postoperative pancreatic fistula (POPF) is the most important factor affecting morbidity and mortality after pancreaticoduodenectomy (PD). Patients with a high controlling nutritional status (CONUT) score, which is used to assess nutritional status, are expected to have high morbidity rates. This study aimed to determine the usefulness of the CONUT score. METHODS: Data from 97 consecutive cases of PD performed in the Department of Surgery of Iwakuni Clinical Center, from April 2008 to May 2018, were included. Preoperative patient data, including sex, age, and hypertension, and postoperative complication data were collected to analyze pancreatic fistula occurrence. RESULTS: Of the 97 patients, 2 9 patients (29.8%) were diagnosed with POPF ≥ B, with 26 cases (26.8%) classified as grade B and 3 (3.1%) as grade C. The mortality rate was 2.1% (2 of 97). In the univariate analysis, a significant association was observed between POPF and the following factors: body mass index (BMI) ≥ 22 kg/m2, high CONUT score, nonpancreatic carcinoma, and CT attenuation values. In multivariate analysis, BMI ≥ 22 kg/m2 (odds ratio [OR], 6.16; P < 0.001), high CONUT score (OR, 3.77; P = 0.009), nonpancreatic carcinoma (OR, 5.72; P = 0.009), and CT attenuation values (late/early ratio) in the pancreas (OR, 9.07; P = 0.006) were independent risk factors for POPF. CONCLUSION: Patients with a high CONUT score are at high risk of POPF. Further study correlating preoperative nutritional intervention with risk of POPF is necessary.

Preoperative C-Reactive Protein/Albumin Ratio as a Predictive Factor for Gallbladder Carcinoma.

BACKGROUND/AIM: The C-reactive protein (CRP) to albumin ratio (CAR) is associated with outcomes in patients with sepsis. We aimed to evaluate the significance of preoperative CAR in therapeutic outcomes after gallbladder carcinoma (GBC) resection. PATIENTS AND METHODS: Fifty-three patients who underwent surgical resection for GBC between January 2008 and September 2019 were enrolled. We retrospectively investigated the relation between preoperative CAR and overall and disease-free survival. RESULTS: The optimal cut-off CAR was 0.07. Multivariate analysis showed that i) R1 or R2 resection (p=0.033), ii) advanced tumor stage (p=0.047), iii) CAR≥0.07 (p=0.011), and iv) postoperative complications (p=0.028) were significant independent predictors of overall survival; moreover, higher carbohydrate antigen levels (p=0.036) and R1 or R2 resection (p<0.001) were significant independent predictors of disease-free survival. CONCLUSION: Preoperative CAR may be a significant independent predictor of long-term outcomes after GBC resection.

Preoperative Nutritional Assessment Using the Controlling Nutritional Status Score to Predict Pancreatic Fistula After Pancreaticoduodenectomy.

Backgound: This study aimed to determine the usefulness of the Controlling Nutritional Status (CONUT) scorescore for predicting postoperative pancreatic fistula (POPF). PATIENTS AND METHODS: Data from 108 consecutive pancreaticoduodenectomy cases performed at the Surgery Department of Iwakuni Clinical Center, from April 2008 to May 2018, were included. Preoperative patient data and postoperative complication data were collected. RESULTS: Of the 108 patients (male=65; female=43; mean age=70 years), 41 (37.9%) had indication for pancreaticoduodenectomy due to pancreatic carcinoma. Grade B or higher POPF was diagnosed in 32 patients (29.6%). In the multivariate analysis, body mass index ≥22 kg/m2 [odds ratio (OR)=5.24; p=0.005], CONUT score ≥4 (OR=3.28; p=0.042), non-pancreatic carcinoma (OR=47.17; p=0.001), and a low computed tomographic contrast attenuation value (late/early ratio) (OR=4.39; p=0.029) were independent risk factors for POPF. CONCLUSION: Patients with high CONUT score are at high risk for POPF. Preoperative nutritional intervention such as immunonutrition might help reduce the POPF risk in these patients.

Adequacy evaluation of the annual colonoscopic surveillance and individual difference of disease phenotypes in Lynch syndrome.

BACKGROUND: Regular endoscopic surveillance for Lynch syndrome is reported to reduce colorectal cancer (CRC)-related mortality. However, the appropriate surveillance intervals are still unclear. We evaluated the adequacy of annual colonoscopy and investigated the differences in tumor occurrence rates between individual patients. METHODS: In total, 25 patients with Lynch syndrome who underwent colonoscopic surveillance between 2007 and 2016 at the Iwakuni Clinical Center were included. We retrospectively investigated the surveillance frequency and the clinical features associated with tumor development. RESULTS: Colonoscopic surveillance was performed every 397 days on average. A total of 101 tumors, including 8 intramucosal carcinomas and 15 carcinomas, were observed within the study period. Annual colonoscopy detected six malignancies, including a carcinoma requiring surgery. Tumor incidence was associated with tumor existence in the initial colonoscopies (P = 0.018). Patients with a tumor occurrence rate of 0.4 tumors per year during our observation period were significantly more likely to have malignancies detected during regular surveillance than patients who had a lower occurrence rate (P < 0.001). Malignancy occurrence rate was strongly associated with tumor occurrence rate (P < 0.001, R2 = 0.44). CONCLUSIONS: Annual colonoscopic surveillance for Lynch syndrome patients was effective in reducing the risk of CRC progression, but was insufficient to completely avoid surgery. Because the tumor occurrence rate differed substantially between individuals, more intensive surveillance was required for high-risk patients.
