Long-Term Survival in Patients With T2 Hepatocellular Carcinoma After Primary Curative Resection Can Be Further Stratified by Tumor Size

Insufficient data are available regarding the validation of long-term survival in patients with T2 (solitary tumor with microvascular invasion [MVI] or multiple tumors, none >5 cm) hepatocellular carcinoma (HCC) after primary hepatectomy. We aim to evaluate the survival and relevant risk factors for T2 HCC patients. Between 2001 and 2007, 312 T2 HCC patients who underwent primary hepatectomy were included. Survival was estimated using the Kaplan–Meier method and compared using Cox proportional hazard model with adjusted independent prognostic factors. The 1, 3, and 5-year overall survival rates of patients with MVI were 85.7%, 68.7%, and 64.8%, respectively; these were inferior to the rates in patients without MVI, which were 93.0%, 89.3%, and 73.7%, respectively (P = 0.037). Within the with-MVI group, the survival rate of patients with tumor sizes ≥5 cm was inferior to that of patients with tumors <5 cm (overall, P = 0.01; recurrence-free, P < 0.0001). For patients with the largest tumors in the <5-cm group, those without MVI tended to have a higher probability of recurrence for 2 years after resection (P = 0.088) but a similar overall survival rate relative to those with MVI (P = 0.31). The crude metastasis-free survival was higher in the without-MVI group than in the with-MVI group (P = 0.012). The T2 HCC category comprised heterogeneous patients with differences in survival rates. Extrahepatic recurrence occurred more frequently in patients with MVI than in those without MVI. These results provide evidence for an updated definition of T2 HCC.     

Somatostatin Receptor SSTR-2a Expression Is a Stronger Predictor for Survival Than Ki-67 in Pancreatic Neuroendocrine Tumors

Somatostatin receptors (SSTR) are commonly expressed by neuroendocrine tumors. Expression of SSTR-2a and SSTR-5 may impact symptomatic management; however, the impact on survival is unclear. The aim of this study is to correlate SSTR-2a and SSTR-5 expression in pancreatic neuroendocrine tumors (PNETs) with survival.This study is designed to determine the prognostic significance of somatostatin receptors SSTR-2a and SSTR-5 in PNETs.This retrospective cohort study included cases of resected PNETs between 1992 and 2014. Clinical data, histopathology, expression of SSTR and Ki-67 by immunohistochemistry, and long-term survival were analyzed.A total of 99 cases were included in this study. The mean age was 57.8 years (18–87 years) and median tumor size was 25 mm (range 8–160 mm). SSTR-2a and SSTR-5 expression was scored as negative (n = 19, 19.2%; n = 75, 75.8%, respectively) and positive (n = 80, 80.1%; n = 24, 24.2%). The median follow-up was 49 months. SSTR-2a expression was associated with improved overall survival, with cumulative survival rates at 1, 3, and 5 years being 97.5%, 91.5%, and 82.9%, respectively. Univariate analysis demonstrated better survival in SSTR-2a positive patients (log rank P = 0.04). SSTR-5 expression was not associated with survival outcomes (log rank P = 0.94). Multivariate analysis showed that positive SSTR-2a expression is a stronger prognostic indicator for overall survival [Hazard Ratio (HR): 0.2, 95% Confidence interval (CI): 0.1–0.8] compared to high Ki-67 (HR: 0.8, 95% CI: 0.1–5.7).Expression of SSTR-2a is an independent positive prognostic factor for survival in PNETs.     

Prognostic Role of Glasgow Prognostic Score in Patients With Hepatocellular Carcinoma: A Systematic Review and Meta-Analysis

Conflicting results about the prognostic value of Glasgow Prognostic Score (GPS) in hepatocellular carcinoma (HCC) patients have been reported. We searched the available articles and performed the meta-analysis to clarify the predictive value of GPS in HCC patients’ outcome.A systematic literature search was conducted using PubMed (Medline), Embase, Cochrane Library, Web of Science, ChinaInfo, and Chinese National Knowledge Infrastructure for all years up to September 2015. Studies analyzing the relationship of GPS and survival outcome were identified. Hazard ratio (HR) with 95% confidence interval (CI) was calculated to assess the risk.A total of 10 studies were finally enrolled in the meta-analysis. The pooled estimates demonstrated a significant relationship between elevated GPS and inferior overall survival in patients with HCC (HR = 2.156, 95% CI: 1.696–2.740, P < 0.001). Patients with increased GPS had a tendency toward shorter progression-free survival (HR = 1.755, 95% CI: 0.943–3.265, P = 0.076). And elevated GPS was found to be significantly associated with advanced Child–Pugh class (odds ratio = 25.979, 95% CI: 6.159–109.573, P < 0.001). The publication bias analysis revealed that there was publication bias in the meta-analysis.Glasgow Prognostic Score may be an independent prognostic factor in patients with HCC. More well-designed studies with adequate follow-up duration are warranted.     

Risk of Early Mortality in Patients With Newly Diagnosed Multiple Myeloma

The overall survival of patients with multiple myeloma (MM) has been improved greatly over the last 2 decades with the broader use of novel drugs and autologous tandem transplantation. However, more than one tenth of myeloma patients still die shortly after diagnosis. We therefore aim to investigate the risk factors of early mortality (death within 60 days after diagnosis) in patients with MM.We included in this study 451 consecutive patients with MM, newly diagnosed at an Asian tertiary medical center between January 1, 2002 and April 30, 2015. A total of 57 subjects who experienced early mortality were identified. Risk factors for early mortality in myeloma patients were collected and analyzed.Early mortality occurred in 57 (12.6%) of the myeloma patients. In the multivariate analysis, being male (adjusted OR 2.93, 95% CI 1.17–7.31), serum albumin < 3.5 g/dL (adjusted OR 2.71, 95% CI 1.09–6.74), primary plasma cell leukemia (adjusted OR 17.61, 95% CI 1.01–306.05), serum albumin (adjusted OR 2.70, 95% CI 1.15–6.38), corrected serum calcium ≥ 12 mg/dL (adjusted OR 2.94, 95% CI 1.21–7.14), and LDH ≥ 250 U/L (adjusted OR 3.07, 95% CI 1.50–6.27) were identified as independent risk factors of early mortality. Pneumonia with other infections contributed most to early mortality (n = 36, 65%), followed by renal failure and cardiac failure.The early mortality rate is high (12.6%) in patients with MM. Patients who are male and those with primary plasma cell leukemia, low serum albumin, high-corrected serum calcium, or LDH are at risk of early mortality. Nearly two thirds of the myeloma patients who experienced early mortality in our study (37 of 57, 65%) died of infection. Once a high-risk group is identified, much effort is required to target new approaches for prevention, early detection, and treatment of infections.     

Factors associated with glycemic control among South African adult residents of Mkhondo municipality living with diabetes mellitus

This study examines the rate and the influencing factors of glycemic control among adult residents living with DM in Mkhondo Municipality of South Africa.In this cross-sectional study, 157 individuals attending care for DM were recruited. Glycemic control status was categorized as poor if glycated hemoglobin (HbA1c) > 7% and very poor if HbA1c ≥ 9%. Multivariate regression analysis was used to identify the significant determinants of poor and very poor glycemic control.The majority of the study participants were females (84.71%) and above 45 years old (88.55%). The overall prevalence of poor glycemic control was 77.71% (n = 122), while very poor glycemic control occurred in 50.6% (n = 80) of the study cohort. In the multivariate logistic regression model analysis, African traditional [AOR = 0.15; 95% confidence interval (95% CI) 0.04–0.57], fast food consumption (AOR = 5.89; 95% CI 2.09–16.81), elevated total cholesterol (TC) [odds ratio (OR) = 2.33; 95% CI 1.50–5.17], elevated low-density lipoprotein cholesterol (LDL-C) (AOR = 5.28; 95% CI 1.89–14.69), and triglyceride (TG) (AOR = 4.39; 95% CI 1.48–13.00) were the independent and significant determinants of poor glycemic control. Age (AOR = 0.46; 95% CI 0.23–0.92) was the only independent and significant determinant of very poor glycemic control.We found a high rate of poor glycemic control (77.71%) possibly attributed to religious affiliation, fast food consumption, and dyslipidemia. On the contrary, about half of the study sample had very poor glycemic control (HbA1c ≥9%), which was predominant among younger cohort with diabetes mellitus. Interventions aimed at improving glycemic control in this population must also target religious practice, dietary patterns and dyslipidemia as well as tailored-approach for young people.     

Prognostic value of targeted temperature management on outcomes of hanging-induced out-of-hospital cardiac arrest: A nationwide observational study

This study aimed to evaluate the prognostic significance of targeted temperature management (TTM) on hanging-induced out-of-hospital cardiac arrest (OHCA) patients using nationwide data of South Korea.Adult hanging-induced OHCA patients from 2008 to 2018 were included in this nationwide observational study. Patients who assigned into 2 groups based on whether they did (TTM group) or did not (non-TTM group) receive TTM. Outcome measures included survival to hospital discharge and a good neurological outcome at hospital discharge.Among the 293,852 OHCA patients, 3545 patients (non-TTM, n = 2762; TTM, n = 783) were investigated. After propensity score matching for all patients, 783 matched pairs were available for analysis. We observed no significant inter-group differences in the survival to hospital discharge (non-TTM, n = 27 [3.4%] vs TTM, n = 23 [2.9%], P = .666) or good neurological outcomes (non-TTM, n = 23 [2.9%] vs TTM, n = 14 [1.8%], P = .183). In the multivariate analysis, prehospital return of spontaneous circulation (odds ratio [OR], 22.849; 95% confidence interval [CI], 11.479–45.481, P < .001) was associated with an increase in survival to hospital discharge, and age (OR, 0.971; 95% CI, 0.944–0.998, P = .035), heart disease (OR, 16.875; 95% CI, 3.028–94.036, P = .001), and prehospital return of spontaneous circulation (OR, 133.251; 95% CI, 30.512–581.930, P < .001) were significant prognostic factors of good neurological outcome. However, TTM showed no significant association with either outcome.There were no significant differences in the survival to hospital discharge and good neurological outcomes between non-TTM and TTM groups of hanging-induced OHCA patients.     

Efficacy of Surgery and Adjuvant Therapy in Older Patients With Colorectal Cancer: A STROBE-compliant article

The present study aimed to assess the efficacy of surgery and adjuvant therapy in older patients (age ≥70 years) with colorectal cancer (CRC). Older CRC patients are under-represented in available clinical trials, and therefore their outcomes after receiving surgery and adjuvant therapy are unclear. From two prospective Swedish databases, we assessed a cohort of 1021 patients who underwent curative surgery for stage I, II, or III primary CRC, with or without adjuvant chemotherapy/radiotherapy. Of the patients with colon cancer (n = 467), 182 (39%) were aged <70 years, 162 (35%) aged 70 to 80 years, and 123 (26%) were aged ≥80 years. Of rectal cancer patients (n = 554), 264 (48%) were aged <70 years, 234 (42%) aged 70 to 80 years, and 56 (10%) aged ≥80 years. Older patients with either colon or rectal cancer had higher comorbidity than did younger patients. Older patients with colon cancer had equivalent postoperative morbidity and 30-day mortality to younger patients. Rectal cancer patients aged ≥80 years had a higher 30-day mortality than younger patients (odds ratio [OR], 2.37; 95% confidence interval [CI], 1.6–4.55; P = 0.03). For either colon or rectal cancer, adjuvant chemotherapy compromised the 5-year overall survival (OS) of older patients with stage II disease and had no effect on those with stage III disease. Receiving adjuvant chemotherapy was a poor factor of OS for older patients with either colon (HR 1.88, 95% CI: 1.20–4.35, P = 0.03) or rectal cancer (HR 1.72, 95% CI: 1.05–2.26, P = 0.004). Preoperative short-course radiotherapy improved both OS and local control for older patients with stage III rectal cancer and had no effect on those with stage II disease. Radiotherapy was a favorable factor for the OS of the older patients with rectal cancer (HR 0.42, 95% CI: 0.21–3.57, P = 0.01). In conclusion, Older CRC patients had equal safety of surgery as younger patients, except rectal cancer patients aged ≥80 years that had a higher mortality. Adjuvant 5FU-based chemotherapy did not benefit older CRC patient, while neoadjuvant radiotherapy improved the prognosis of older patients with stage III rectal cancer.     

The Outcomes and Prognostic Factors of the Very Elderly Requiring Prolonged Mechanical Ventilation in a Single Respiratory Care Center

This study investigated the outcomes and the prognostic factors among the very elderly (patients ≥80 years old) requiring prolonged mechanical ventilation (PMV).Between 2006 and 2014, all of the very elderly patients of age 80 or more transferred to respiratory care center (RCC) of a tertiary medical center were retrospectively identified, and only patients who used mechanical ventilation (MV) for >3 weeks were included in this study.A total of 510 very elderly patients undergoing PMV were identified. The mean age of the patients was 84.3 ± 3.3 years, and it ranged from 80 to 96 years. Male comprised most of the patients (n = 269, 52.7%), and most of the patients were transferred to RCC from medical ICU (n = 357, 70.0%). The APACHE II scores on RCC admission was 17.6 ± 6.0. At least 1 comorbidity was found in 419 (82.2%) patients. No significant differences of gender, disease severity, diagnosis, dialysis, laboratory examinations, comorbidities, and outcome were found between octogenarians (aged 80–89) and nonagenarians (aged ≥ 90). The overall in-hospital mortality rate was 21.8%. In the multivariate analysis, patients who had APACHE II score ≥ 15(odds ratio [OR], 2.30, 95% confidence interval [CI], 1.36–3.90), or albumin ≤ 2 g/dL (OR, 3.92, 95% CI, 2.17–7.01) were more likely to have significant in-hospital mortality (P < 0.05).The in-hospital mortality rate of the very elderly PMV patients in our RCC is 21.8%, and poor outcomes in this specific population were found to be associated with a higher APACHE II score and lower albumin level.     

Risk factors for postoperative pneumonia and prognosis in lung cancer patients after surgery: A retrospective study

Postoperative pneumonia (POP) is one of the most frequent complications following lung surgery. The aim of this study was to identify the risk factors for developing POP and the prognostic factors in lung cancer patients after lung resection.We performed a retrospective review of 726 patients who underwent surgery for stages I–III lung cancer at a single institution between August 2017 and July 2018 by conducting logistic regression analysis of the risk factors for POP. The Cox risk model was used to analyze the factors influencing the survival of patients with lung cancer.We identified 112 patients with POP. Important risk factors for POP included smoking (odds ratio [OR], 2.672; 95% confidence interval [CI], 1.586–4.503; P < .001), diffusing capacity for carbon monoxide (DLCO) (40–59 vs ≥80%, 4.328; 95% CI, 1.976–9.481; P < .001, <40 vs ≥80%, 4.725; 95% CI, 1.352–16.514; P = .015), and the acute physiology and chronic health evaluation (APACHE) II score (OR, 2.304; 95% CI, 1.382–3.842; P = .001). In the Cox risk model, we observed that age (hazard ratios (HR), 1.633; 95% CI, 1.062–2.513; P = .026), smoking (HR, 1.670; 95% CI, 1.027–2.716; P = .039), POP (HR, 1.637; 95% CI, 1.030–2.600; P = .037), etc were predictor variables for patient survival among the factors examined in this study.The risk factors for POP and the predictive factors affecting overall survival (OS) should be taken into account for effective management of patients with lung cancer undergoing surgery.     

Simple prognostic markers for optimal treatment of patients with unresectable pancreatic cancer

Most patients with pancreatic cancer are ineligible for curative resection at diagnosis, resulting in poor prognosis. This study aimed to evaluate the prognostic factors in patients with unresectable pancreatic cancer.We retrospectively collected clinical data from 196 patients with unresectable pancreatic cancer who received palliative chemotherapy (N = 153) or palliative care alone (N = 43) from January 2011 to December 2013. Patients’ background data and overall survival were analyzed using the Cox proportional hazard regression model.In patients receiving palliative chemotherapy (gemcitabine-based regimen, 88.2%) and palliative care alone, the median (range) ages were 68 (43–91) and 78 (53–90) years, and metastatic diseases were present in 80% (N = 123) and 86% (N = 37), respectively. Multivariate analysis in the palliative chemotherapy patients showed that liver metastasis (hazard ratio [HR] 2.25, 95% confidence interval [CI] 1.58–3.20, P < .001), neutrophil-to-lymphocyte ratio (>4.5 vs ≤4.5; HR 3.45, 95% CI 2.22–5.36, P < .001), and cancer antigen 19-9 (CA19-9) (≥900 vs <900 U/mL; HR 1.45, 95% CI 1.02–2.05, P = .036) were independent prognostic factors. In those receiving palliative care alone, lung (HR 3.27, 95% Cl 1.46-7.35, p = 0.004) and peritoneum (HR 2.50, 95% CI 1.20–5.18, P = .014) metastases and the C-reactive protein-to-albumin ratio (≥1.3 vs <1.3; HR 3.33, 95% Cl 1.51–7.35, P = .003) were independent prognostic factors. Furthermore, patients with multiple factors had worse prognosis in both groups. Median survival time of palliative chemotherapy patients with risk factors 0, 1, 2, and 3 were 13.1 (95% CI 8.0–16.9), 9.4 (95% CI 7.9–10.1), 6.6 (95% CI 4.9–7.8), and 2.5 (95% CI 1.7–4.0) months, respectively. Similarly, median survival time was 5.7 (95% CI 1.3 -8.0), 2.1 (95% CI 1.5–3.9), and 1.3 (95% CI 0.6–1.7) months, respectively, for palliative care alone patients with risk factor 0, 1, and 2 to 3.Prognostic markers for pancreatic cancer were neutrophil-to-lymphocyte ratio, liver metastasis, and CA19-9 in patients undergoing palliative chemotherapy and C-reactive protein-to-albumin ratio and lung/peritoneum metastases in patients undergoing palliative care alone. These simple markers should be considered when explaining the prognosis and therapeutic options to patients.     

Risk factors of delayed recovery from general anesthesia in patients undergoing radical biliary surgery: What can we prevent

Delayed recovery (DR) is very commonly seen in the patients undergoing laparoscopic radical biliary surgery, we aimed to investigate the potential risk factors of DR in the patients undergoing radical biliary surgery, to provide evidences into the management of DR.Patients who underwent radical biliary surgery from January 1, 2018 to August 31, 2020 were identified. The clinical characteristics and treatment details of DR and no-DR patients were compared and analyzed. Multivariable logistic regression analyses were conducted to identify the potential influencing factors for DR in patients with laparoscopic radical biliary surgery.We included a total of 168 patients with laparoscopic radical biliary surgery, the incidence of postoperative DR was 25%. There were significant differences on the duration of surgery, duration of anesthesia, and use of intraoperative combined sevoflurane inhalation (all P < .05), and there were not significant differences on American Society of Anesthesiologists, New York Heart Association, tumor-lymph node- metastasis, and estimated blood loss between DR group and control group (all P > .05). Multivariable logistic regression analyses indicated that age ≥70 years (odd ratio [OR] 1.454, 95% confidence interval [CI] 1.146–1.904), body mass index ≥25 kg/m² (OR 1.303, 95% CI 1.102–1.912), alcohol drinking (OR 2.041, 95% CI 1.336–3.085), smoking (OR 1.128, 95% CI 1.007–2.261), duration of surgery ≥220 minutes (OR 1.239, 95% CI 1.039–1.735), duration of anesthesia ≥230 minutes (OR 1.223, 95% CI 1.013–1.926), intraoperative combined sevoflurane inhalation (OR 1.207, 95% CI 1.008–1.764) were the independent risk factors for DR in patients with radical biliary surgery (all P < .05).It is clinically necessary to take early countermeasures against various risk factors to reduce the occurrence of DR, and to improve the prognosis of patients.     

Clinicopathological and prognostic value of preoperative lymphocyte to monocyte ratio for hepatocellular carcinoma following curative resection: A meta-analysis including 4,092 patients

Background:Previous studies have reported that lymphocyte-to-monocyte ratio (LMR) had novel prognostic value in hepatocellular carcinoma (HCC). The purpose of this meta-analysis was to synthetically evaluate the prognostic role of preoperative LMR in HCC patients following curative resection.Methods:Eligible studies were acquired through searching Pubmed, Web of Science, Cochrane Library and EMbase update to September 2019. Merged hazard ratios (HRs) and 95% confidence intervals (CIs) were applied as effect sizes.Results:A total of ten studies containing 4,092 patients following liver resection were enrolled in this meta-analysis. The pooled results demonstrated that preoperative elevated LMR indicated superior survival outcome (HR: 0.58, 95% CI: 0.34–0.96, P = .035) and recurrence-free survival (RFS)/disease-free survival/time to recurrence (HR = 0.76, 95% CI: 0.58–0.98, P = .034). The significant prognostic role of preoperative LMR was detected in the subgroup of all publication year, country of origin, sample sizes <300, TNM stage of I–IV and LMR cut-off value ≤4. Furthermore, high LMR was significantly associated with male, high AFP, large tumor size, incomplete tumor capsule, advanced TNM stage and BCLC stage, and presence of PVTT.Conclusion:Elevated preoperative LMR indicated superior survival outcome in HCC patients following curative resection, and might serve as a novel prognostic biomarker.     

Metabolic syndrome in Zambian adults with human immunodeficiency virus on antiretroviral therapy: Prevalence and associated factors

Metabolic syndrome (MetS) is a constellation of factors including hypertension, abdominal obesity, dyslipidemia, and insulin resistance that separately and together significantly increase risk for cardiovascular disease (CVD) and diabetes. In sub-Saharan Africa, with a substantial burden of human immunodeficiency virus (HIV) and increasing prevalence of CVD and diabetes, there is a paucity of epidemiological data on demographic, laboratory, and clinical characteristics associated with MetS among people with HIV (people with human [PWH]). Therefore, this study aimed to determine the burden and factors influencing MetS in antiretroviral therapy (ART)-experienced individuals in Zambia.We collected cross-sectional demographic, lifestyle, anthropometric, clinical, and laboratory data in a cohort of ART-experienced (on ART for ≥6 months) adults in 24 urban HIV treatment clinics of Zambia between August, 2016 and May, 2020. MetS was defined as having ≥3 of the following characteristics: low high density lipoprotein cholesterol (HDL-c) (<1.0 mmol/L for men, <1.3 for women), elevated waist circumference (≥94 cm for men, ≥80 cm for women), elevated triglycerides (≥1.7 mmol/L), elevated fasting blood glucose (≥5.6 mmol/L), and elevated blood pressure (BP) (systolic BP ≥130 or diastolic BP ≥85 mm Hg). Virological failure (VF) was defined as HIV viral load ≥1000 copies/mL. The following statistical methods were used: Chi-square test, Wilcoxon rank-sum test, and multivariable logistic regression.Among 1108 participants, the median age (interquartile range [IQR]) was 41 years (34, 49); 666 (60.1%) were females. The prevalence of MetS was 26.3% (95% confidence interval [CI] 23.9–29.1). Age (adjusted odds ratio [OR] 1.07; 95% CI 1.04–1.11), female sex (OR 3.02; 95% CI 1.55–5.91), VF (OR 1.98; 95% CI 1.01–3.87), dolutegravir (DTG)-based regimen (OR 2.10; 95% CI 1.05–4.20), hip-circumference (OR 1.03; 95% CI 1.01–1.05), T-lymphocyte count (OR 2.23; 95% CI 1.44–3.43), high-sensitivity C-reactive protein (hsCRP) (OR 1.14; 95% CI 1.01–1.29), and fasting insulin (OR 1.02; 95% CI 1.01–1.04) were significantly associated with MetS.Metabolic syndrome was highly prevalent among HIV+ adults receiving ART in Zambia and associated with demographic, clinical, anthropometric, and inflammatory characteristics. The association between MetS and dolutegravir requires further investigation, as does elucidation of the impact of MetS on ART outcomes in sub-Saharan African PWH.     

Predictors of Mortality Within 6 Weeks After Treatment of Gastric Variceal Bleeding in Cirrhotic Patients

Acute gastric variceal bleeding (GVB) is a catastrophic problem and accounts for one of the major causes of death in cirrhotic patients. Although, N-butyl cyanoacrylate (NBC) has been shown to control bleeding effectively, it still carries up high mortality rate. This study aimed to find the predictors of mortality within 6 weeks after emergent endoscopic treatment with NBC injection.This retrospective study recruited patients with acute GVB after emergent endoscopic NBC injection between January 2011 and June 2013 in Linkou Medical Center, Chang Gung Memorial Hospital, Linkou, Taiwan. Logistic regression analysis was applied for predictors of mortality within 6 weeks. Statistical significance was set as P < 0.05.There were 132 patients with acute GVB (83.3% men, median age 51.3 years) with endoscopic NBC injection treatments recruited. Mortality within 6 weeks was noted in 16.7% patients. By multivariate analysis, renal function impairment (odds ratio [OR]: 21.1, 95% confidence interval [CI]: 3.06–146.0, P = 0.002), higher Child–Turcotte–Pugh (CTP) score (OR: 2.49, 95% CI: 1.41–4.38, P = 0.002), higher model for end-stage liver disease (MELD) score (OR: 1.18, 95% CI: 1.03–1.35, P = 0.013), rebleeding within 5 days (OR: 16.4, 95% CI: 3.36–79.7, P = 0.001), and acute on chronic liver failure (ACLF) (OR: 4.67, 95% CI: 1.62–13.33, P = 0.004) were independent predictors of mortality within 6 weeks. A MELD score of ≥18 was associated with Area Under the Receiver Operating Characteristic (AUROC) of 0.79 (P < 0.001, 95% CI: 0.69–0.90) and a CTP score of ≥9 with AUROC of 0.85 (P < 0.001, 95% CI: 0.76–0.94) for determining 6 weeks mortality.Impaired renal function, deteriorated liver function with CTP score ≥ 9 as well as MELD score ≥18, rebleeding within 5 days, and ACLF are independent predictors of mortality.     

The Association Between Body Mass Index and the Prognosis and Postoperative Complications of Hepatocellular Carcinoma: A Meta-Analysis

Previous studies have reported the association between excess body mass index (BMI) and increased risk of hepatocellular carcinoma (HCC). However, whether BMI is associated with the prognosis and postoperative complications of HCC is still not clear.We searched PubMed and Embase for relevant studies published until the date of August 30, 2014. Additional studies were manually identified by searching reference lists of retrieved articles. Pooled hazard ratios (HRs) with 95% confidence intervals (95% CIs) for overall survival (OS), disease-free survival (DFS), and risk ratios (RRs) with 95% CIs for postoperative complications were calculated using random effects or fixed effects models according to heterogeneities between studies.A total of 14 studies were included in the present meta-analysis. The pooled results showed that excess BMI was not significantly associated with improved OS (HR = 0.94; 95% CI: 0.74–1.19, P = 0.588) or DFS (HR = 0.93; 95% CI: 0.79–1.10, P = 0.382). In addition, higher BMI was not associated with increased rate of a number of complications including ascites (RR = 1.25, 95% CI: 0.94–1.65, P = 0.119), bile leaks (RR = 1.22, 95% CI: 0.81–1.83, P = 0.345), and 30-day mortality (RR = 1.05, 95% CI: 0.57–1.96, P = 0.871). However, HCC patients with higher BMI had increased incidence of wound infections (RR = 2.17, 95% CI: 1.28–3.68, P = 0.004).BMI was not an independent prognostic factor for the evaluation of the prognosis in HCC patients, and it was not associated with postoperative complications except for wound infections that as significantly associated with higher BMI scores.     

Fasting blood glucose was linearly associated with colorectal cancer risk in the population without self-reported diabetes mellitus history

Fasting plasma glucose level was linearly associated with colorectal cancer (CRC) risk. However, the dose–response relationship between fasting blood glucose (FBG) and CRC risk was still uncertain.A total of 11,632 patients without self-reported diabetes mellitus and colorectal polyps’ history were identified in the Korean Multicenter Cancer Cohort (1993–2005). The nonlinear relationship was estimated through a restricted cubic spline regression, and a two-piece-wise Cox proportional hazards model was further performed to calculate the threshold effect. Multiple imputation was used to control the bias from missing data.Overall, 1.1% (n = 132) of participants were diagnosed with CRC in the follow-up duration. With a median follow-up duration of 12.0 years, participants with FBG ≥126 mg/dL were associated with higher CRC risk (adjusted hazard ratio [HR], 1.67; 95% confidence interval [CI]: 1.01, 2.76). Landmark analyses limited to long-term survivors demonstrated increased CRC risk with FBG ≥ 126 mg/dL in all subsets (≥3years: HR,1.93 (95% CI: 1.13–3.29); ≥5years: HR, 2.04 (95% CI: 1.–3.63); ≥10years: HR, 2.50 (95% CI: 1.19–5.25)). With FBG smoothly increasing before, the latter increased dramatically after the turning point (P for nonlinearity = 0.283). When FBG was increasing per mmol/L, HR was 1.07(95% CI: 0.90, 1.29) for FBG < 126 mg/dL and 1.27 (95% CI: 1.06, 1.53) for FBG ≥ 126 mg/dL. Besides, HR was 1.09 (95% CI: 1.02, 1.16) for the CRC risk.In the population without self-reported diabetes mellitus and colorectal polyps’ history. FBG was linearly associated with CRC risk, especially for FBG over 126 mg/dL.     

Preoperative Neutrophil-to-lymphocyte Ratio Predicts Long-term Survival in Patients Undergoing Total Laryngectomy With Advanced Laryngeal Squamous Cell Carcinoma: A Single-center Retrospective Study

There is increasing evidence that the neutrophil-to-lymphocyte ratio (NLR) is a stage-independent predictor of poor outcome in patients with cancer. The purpose of this study was to investigate the association between cancer-specific survival (CSS), overall survival (OS), and the preoperative NLR in patients with advanced laryngeal squamous cell carcinoma (LSCC) undergoing total laryngectomy (TL).All patients with a new diagnosis of advanced laryngeal cancer (stages III and IV) presenting at the Department of Head and Neck Oncology, Sun Yat-sen University Cancer Center between January 1990 and July 2010 (n = 420) were included. To evaluate the independent prognostic relevance of the NLR, univariate and multivariate Cox regression models were used. CSS and OS were estimated using the Kaplan-Meier method.Four-hundred twenty patients were enrolled in this study. Patients with an NLR ≥2.59 showed a significantly lower CSS (P = .014) and OS (P = .032) than patients with an NLR <2.59. The Cox proportional multivariate hazard model showed that a higher preoperative NLR was independently correlated with a poor CSS and OS, with hazard ratios of 1.42 (95% confidence interval [CI] 1.06–1.91, P = .018) and 1.31 (95% CI 1.00–1.71, P = .046), respectively.The NLR may be an independent prognostic marker for CSS and OS in patients with advanced LSCC undergoing TL.     

Age-Adjusted Charlson Comorbidity Index Scores as Predictor of Survival in Colorectal Cancer Patients Who Underwent Surgical Resection and Chemoradiation

We studied the effect of Age-Adjusted Comorbidity Index Score in colorectal cancer patients who underwent similarly aggressive treatment.Using the National Health Insurance Research Database of Taiwan, we identified 5643 patients with colorectal cancer who underwent surgical resection and chemoradiation from 2007 through 2011. We estimated survival according to Age-Adjusted Comorbidity Index Scores and 5-year survival using Cox proportional hazard regression analysis, adjusting for sex, oxaliplatin-based chemotherapy, socioeconomic status, geographic region, and hospital characteristics.In the cohort were 3230 patients with colonic cancer and 2413 patients with rectal cancer, who had undergone combined surgical resection and either neoadjuvant or adjuvant chemoradiation. After adjusting for patient characteristics (sex, oxaliplatin-based chemotherapy, socioeconomic status, geographic region, and hospital-characteristics), colonic cancer patients with age-adjusted Charlson (AAC) ≥6 had a 106% greater risk of death within 5 years (adjusted HR = 2.06; 95% CI, 1.66–2.56). In rectal cancer patients, patients with an AAC score of 4–5 had a 28% greater risk of death within 5 years (adjusted HR = 1.28; 95% CI, 1.02–1.61), and those with AAC ≥6 had a 47% greater risk (adjusted HR = 1.47; 95% CI, 1.15–1.90).Age and burden of comorbidities influence survival of patients with colonic or rectal cancer. Age-Adjusted Comorbidity Score remains an independent prognostic factor even after adjusting for the aggressiveness of treatment.     

Prevalence and Risk Factors of Acute Lower Gastrointestinal Bleeding in Crohn Disease

Acute lower gastrointestinal bleeding (ALGIB) is a rare but potentially life-threatening complication of Crohn disease (CD). Thus far, few studies of ALGIB in the context of CD have been published, most of which were case reports with limited value. We aimed to explore the prevalence of ALGIB in CD patients, evaluate risk factors for hemorrhagic CD and its recurrence, and analyze clinical data of the death cases.A total of 1374 CD patients registered from January 2007 to June 2013 were examined. Medical records of 73 patients with ALGIB and 146 matched as controls were reviewed and analyzed retrospectively. Logistic regression and Cox proportional hazards analyses were performed to identify risk factors for ALGIB and the cumulative probability of rebleeding. Kaplan–Meier curves with log-rank tests were used to demonstrate the cumulative survival rates of rebleeding.The prevalence of ALGIB was 5.31% (73/1374) in this study. In the univariate analysis, possible risk factors for ALGIB were duration of CD (odds ratio [OR] 0.60, 95% confidence interval [CI] 0.33–1.09, P = 0.095), perianal disease (OR 1.96, 95% CI 0.92–4.20, P = 0.082), left colon involvement (OR 2.16, 95% CI 1.10–4.24, P = 0.025), azathioprine use ≥1 year (OR 0.46, 95% CI 0.23–0.90, P = 0.023), and previous hemorrhage history (OR 11.86, 95% CI 5.38–26.12, P < 0.0001). In the multivariate analysis, left colon involvement (OR 2.26, 95% CI 1.04–4.91, P = 0.039), azathioprine use ≥1 year (OR 0.44, 95% CI 0.20–0.99, P = 0.044), and previous hemorrhage history (OR 13.04, 95% CI 5.66–30.04, P < 0.0001) remained independent influencing factors. Older age (HR 0.23, 95% CI 0.07–0.77, P = 0.018), surgical treatment (HR 0.17, 95% CI 0.06–0.50, P < 0.001), and having bleeding episodes >3 months ago (HR 0.24, 95% CI 0.07–0.82, P = 0.022) resulted to be predictors associated with rebleeding after discharge. Patients who died often suffered severe concomitant diseases, and the overall mortality rate was 8.22% (6/73).We speculated that a special hemorrhagic phenotype of CD that was predisposed to rebleeding may exist. Further studies are warranted to investigate the pathogenesis and discover the optimum treatments of choice.
