Abstract Background This study aimed to assess the prognostic factors including low skeletal muscle mass index (SMI) and perioperative blood transfusion for patients with hepatocellular carcinoma (HCC) following curative surgery. Methods This study included 139 patients with HCC who underwent hepatectomy between 2005 and 2016. Univariate and multivariate analyses were performed to identify variables associated with overall survival (OS) and recurrence-free survival (RFS). Results Low SMI was significantly related with poor OS, while blood transfusion had a strong impact on RFS. The male ratio and body mass index in the low SMI group were significantly higher than those in the high SMI group. There were no significant differences in age, virus etiology, laboratory data, liver function, tumor makers, and operative variables between the groups. Tumor factors such as tumor diameter, tumor number, poor differentiation, and intrahepatic metastasis (IM) did not significantly differ between the two groups. Operation time, intraoperative blood loss volume, and recurrence ratio were significantly higher in the blood transfusion group than in the non-transfusion group. IM was associated with poor OS and RFS. Conclusions Low SMI and blood transfusion were independently related with long-term prognosis in patients with HCC following curative surgery.

Abstract Background Postoperative pancreatic fistula (POPF) is a life-threatening postoperative complication. The aim of this study was to evaluate the efficacy of the fistula risk score (FRS) and preoperative body composition factors for predicting the occurrence of clinically relevant POPF (CR-POPF) after pancreaticoduodenectomy (PD). Methods In this study, 136 consecutive patients who underwent PD between 2006 and 2018 were enrolled. The risk factors of CR-POPF (grades B and C) were analyzed. Preoperative visceral adipose tissue area (VATA), skeletal mass index (SMI), and subcutaneous adipose tissue area (SATA) were calculated from computed tomography data. Results The overall 30-day mortality and morbidity rates were 0.7 and 38%, respectively. The incidence rates of grade B and C CR-POPF were 27 and 4%, respectively. A univariate analysis revealed that male sex, habitual smoking, prognostic nutritional index (PNI) 4 were significantly associated with the incidence of CR-POPF. A multivariate analysis revealed that PNI 4 were the independent risk factors of CR-POPF. Conclusions Preoperative anthropomorphic imbalance, PNI, and FRS were independent risk factors for CR-POPF. Patients with high-risk factors should be closely monitored during the postoperative period.

Abstract Background Gastric cancer (GC) is the third leading cause of cancer-related mortality worldwide. Therefore, identifying the predictive factors for surgical morbidity, disease recurrence, and long-term survival is necessary for preventing GC patient mortality. We aimed to evaluate the factors that contribute to the poor prognoses of GC patients. Methods In this retrospective cohort study, the data of 182 patients who underwent curative gastrectomy for GC was reviewed. The data included patients’ cancer stage and preoperative prognostic nutritional index (PNI) score. We identified the prognostic factors using a univariate analysis and the multivariable Cox proportional hazards model. The associations between PNI and other clinicopathologic factors for GC were compared via logistic regression analysis. Kaplan-Meier curves were used to evaluate patients’ survival in relation to these factors. The median follow-up period was 3.5 years. Multivariable cumulative incidence method based on Fine and Gray’s method was performed to evaluate the association between non GC-related death and potential prognostic factors. Results There were significant differences in overall survival (OS) between comorbidities (myocardial infarction: P = 0.040, liver disease: P = 0.017), cancer stages (I vs. II: P = 0.049, I vs. III: P
