Radical resection benefits patients suffering pancreatic ductal adenocarcinoma with liver oligometastases.

Purpose: Whether patients suffering liver oligometastases from pancreatic ductal adenocarcinoma (LOPDA) should undergo surgical treatment remains controversial. Methods: PubMed and Embase databases were systematically reviewed until 2023 June. Survival data were collected from the Kaplan-Meier curves. Safety and survival were evaluated using primary outcomes such as 1-year, 3-year, and 5-year survival rates, and 30-day mortality and morbidity. A subgroup meta-analysis was conducted to compare survival rates post-synchronous resection and resection post-neoadjuvant chemotherapy in LOPDA. Results: Our analysis of 15 studies involving 1,818 patients (surgical group, 648 and nonsurgical group, 1,170) indicates that radical hepatectomy for LOPDA notably improved 1-year (odds ratio [OR], 3.24; 95% confidence interval [CI], 2.45-4.28; P < 0.001), 3-year (OR, 5.74; 95% CI, 3.36-8.90; P < 0.001), and 5-year (OR, 4.89; 95% CI, 2.56-9.35; P < 0.001) overall survival (OS) rates. A separate analysis of 6 studies with 750 patients demonstrated the safety of LOPDA surgery, with no increase in postoperative complications (P = 0.26 for overall morbidity and P = 0.99 for mortality) compared to the patients with no metastatic disease from the pancreatic ductal adenocarcinoma (NMPDA) group. The NMPDA group showed superior 1-year and 3-year OS rates, but not 5-year OS rates compared to the LOPDA group. Conclusion: Surgical treatment apparently offers a survival advantage to LOPDA by comparing with nonsurgical groups in 1-, 3-, and 5-year OS rates. Radical resection for LOPDA is a safe treatment without more postoperative complications than NMPDA.

The Impact of Imaging-Diagnosed Sarcopenia on Long-term Prognosis After Curative Resection for Hepatocellular Carcinoma: A Systematic Review and Meta-analysis.

BACKGROUND: Recent research suggests that sarcopenia potentially influences the long-term postoperative prognosis of malignant tumors. Thus, the primary objective of this study was to investigate the impact of imaging-diagnosed sarcopenia on the long-term prognosis of hepatocellular carcinoma (HCC) patients after curative resection. METHODS: In our approach, all studies incorporated in this study employed Cox proportional hazards models with multivariable adjusted hazard ratios. The meta-analysis was performed using R statistical software. The primary outcomes were quantified using hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: This study analyzed 30 studies, involving 7352 HCC patients after curative resection (2695 in the sarcopenia group and 4657 in the non-sarcopenia group). The meta-analysis of 28 studies indicated that patients in the sarcopenia group demonstrated notably inferior overall survival (OS) compared with the non-sarcopenia group (HR=2.20; 95% CI, 1.88-2.58; p < 0.01). Similarly, sarcopenia exhibits a significant association with poor recurrence-free survival (RFS) and disease-free survival (DFS) based on 16 and 6 studies (HR=1.50; 95% CI, 1.39-1.63; p < 0.01 and HR=1.96; 95% CI, 1.83-2.10; p < 0.01, respectively). CONCLUSION: In conclusion, imaging-diagnosed sarcopenia adversely affects the long-term prognosis, including OS, RFS, and DFS, in HCC patients after curative resection. The findings hold considerable importance in guiding comprehensive healthcare procedures for HCC patients after surgery.

Enhanced prognosis of HCC patients undergoing radical treatments with tenofovir versus entecavir: A meta-analysis based on propensity score matching studies.

The selection of postoperative antiviral therapy for hepatocellular carcinoma (HCC) patients with HBV infection undergoing radical treatments (HPHR) is a topic of ongoing debate and controversy. The primary aim of this study was to compare the prognostic impact of selecting entecavir (ETV) or tenofovir disoproxil fumarate (TDF) as antiviral therapy options in HPHR. All the studies included in this analysis were implemented propensity score matching (PSM) methodology. Meta-analysis was performed using R statistical software (version 4.3.0). The primary outcome measures, overall survival (OS) and recurrence-free survival (RFS), were quantified using hazard ratios (HR) and 95% confidence intervals (CI). This study analyzed 13 studies involving 6961 patients (2394 in the TDF group and 4567 in the ETV group). We conducted a meta-analysis of 8 studies that included a total of 5289 patients using the PSM analysis method. In comparison to the ETV group, the TDF group demonstrated significantly better RFS (HR = 0.81; 95% CI, 0.70-0.93; p = 0.0034) and OS (HR = 0.61; 95% CI, 0.42-0.88; p = 0.0085). Furthermore, the disparity between the two drugs was particularly evident in the prognosis of patients undergoing hepatectomy. Regional disparities were observed, with mainland China studies favoring RFS benefits and Taiwan or Korea studies favoring OS benefits. In conclusion, TDF has demonstrated significant superiority over ETV in terms of RFS and OS outcomes for HPHR. The findings hold significant implications for informing clinical decision-making and guiding the selection of postoperative antiviral therapy drugs in HCC patients.

Sarcopenia Imperils Postoperative Long-Term Survival in HCC Patients with Metabolic Dysfunction-Associated Fatty Liver Disease: A Propensity Score Matching Analysis.

Background: Recent research has suggested that sarcopenia may have an impact on postoperative outcomes. The number of hepatocellular carcinoma (HCC) patients with metabolic dysfunction-associated fatty liver disease (MAFLD) has increased significantly over time. The main objective of this study was to investigate the impact of sarcopenia on the prognosis of HCC patients with MAFLD after hepatectomy. Methods: A multivariate Cox proportional hazards model and a propensity score matching (PSM) analysis were conducted to ensure that the baseline characteristics were similar. Kaplan‒Meier survival curves were used to compare the prognosis of the two groups. Results: This study involved 112 HCC patients with MAFLD undergoing hepatectomy. Sarcopenia was indicated as a risk factor for both recurrence-free survival (RFS) and overall survival (OS) in HCC patients with MAFLD after multivariate analysis (p=0.002 and 0.022, respectively). After conducting PSM analysis, Kaplan‒Meier survival curve analysis revealed significant differences in both the RFS and OS between the two groups (p=0.0002 and p=0.0047, respectively). All results showed that sarcopenia had a poor prognosis for HCC patients with MAFLD undergoing hepatectomy. Conclusion: In summary, our study suggests that sarcopenia might be a risk factor for OS and RFS in HCC patients with MAFLD who underwent hepatectomy through multivariate analysis and PSM analysis. Sarcopenia imperils postoperative survival rates and this finding can guide clinical decision-making. For postoperative patients, preventing or treating sarcopenia can potentially improve survival outcomes for patients with HCC and MAFLD.

The role of noninvasive scoring systems for predicting cardiovascular disease risk in patients with nonalcoholic fatty liver disease: a systematic review and meta-analysis.

BACKGROUNDS: Cardiovascular disease (CVD) is suggested as a leading cause of death among patients with nonalcoholic fatty liver disease (NAFLD). The aim of this work was to clarify the role of noninvasive scoring systems (NSSs) in predicting CVD risk among this population. METHODS: The PubMed, Web of Science, and Cochrane databases were searched until 23 March 2022. Meta-analysis was performed for three most commonly used NSS separately, that is, fibrosis-4 index (FIB-4), NAFLD fibrosis score (NFS), and AST/platelet ratio index (APRI). RESULTS: Totally, nine studies including 155 382 patients with NAFLD were enrolled. Patients with NAFLD had a higher risk of CVD with increasing FIB-4 score (1.94, 1.52-2.46), the association remained significant after adjustment for age, sex, body mass index, hypertension, and diabetes (2.44, 1.85-3.22). Similarly, a higher risk of CVD was also observed in patients with increasing NFS (2.17, 1.58-2.98) and APRI scores (1.36, 1.04-1.79) in the unadjusted model. However, in the adjusted model, the association was significant only for NFS (3.83, 1.40-10.43), but not for APRI (1.41, 0.79-2.51). Additionally, the increment in CVD risk was most noticeable in subgroup of FIB > 2.67 vs. FIB ≤ 1.3 (6.52, 3.07-13.86) and subgroup of NFS > 0.676 vs. NFS ≤ -1.455 (16.88, 5.68-50.23). All subgroup analyses showed significant associations between FIB-4, NFS, and risk of CVD. Sensitivity analyses did not modify these results. CONCLUSIONS: FIB-4 and NFS might be useful in identifying those who are at higher risk of CVD among patients with NAFLD. However, APRI was not recommended for this use.

Extrahepatic morbidities and mortality of NAFLD: an umbrella review of meta-analyses.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) has reached pandemic proportions currently and may contribute to multiple extrahepatic outcomes. AIM: To comprehensively summarise evidence of associations between NAFLD and risk of extrahepatic outcomes. METHODS: We conducted an umbrella review. We searched PubMed, Web of Science and Cochrane database from inception to 27 November 2021. RESULTS: We included 22 meta-analyses with 374 original studies in our analysis. Subjects with NAFLD had an increased risk of mortality, multiple cardiovascular complications, extrahepatic cancers, diabetes and chronic kidney disease (CKD) than those without NAFLD. Excess risks of several other extrahepatic outcomes including hypothyroidism, urolithiasis, gastro-oesophageal reflux disease, gallstones, depression and worse maternal and foetal outcomes were also observed in this population. However, associations were not significant for prostate cancer, female organ genital cancer, haematological cancer, diabetic retinopathy or osteoporotic fracture. The risks of CVD, diabetes and CKD were similar in obese and non-obese patients. Most associations were heterogeneous across regions; significantly, Europeans with NAFLD were more prone to all-cause mortality than North Americans. The certainty of evidence was graded from only very low to moderate as all included studies were observational. CONCLUSIONS: Patients with NAFLD are at heightened risk of extrahepatic outcomes. However, the certainty of evidence is only from very low to moderate. Further studies at low risk of bias are required to support the evidence and elucidate any causal associations.

Lactoferrin protects against lipopolysaccharide-induced acute lung injury in mice.

Lactoferrin (LF) plays various anti-inflammatory roles in inflammation experimentally induced by lipopolysaccharides (LPS). But the protective effects of LF on LPS-induced acute lung injury (ALI) have not been elucidated. In this study, we aimed to study the effects of LF on ALI caused by LPS in mice. At 1h before or after LPS injection, an intraperitoneal injection of LF (5mg/body) was administered. Lung specimens and the bronchoalveolar lavage fluid (BALF) were isolated for histopathological examinations and biochemical analyses 12h after LPS exposure. We found that both prophylactic and therapeutic administration of LF significantly decreased the W/D ratio of the lung and protein concentration in the BALF. LF significantly reduced the pulmonary myeloperoxidase activity and the number of total cells in the BALF 12h after LPS challenge. LF treatment markedly attenuated lung edema, alveolar hemorrhage and inflammatory cells infiltration. Moreover, LF also decreased the production of TNF-α and increased interleukin-10 in the BALF. These results firstly indicate that LF may protect against LPS-induced ALI in mice.
