Patients with pancreatic ductal adenocarcinoma (PDAC) with peritoneal dissemination have a dismal prognosis because discontinuation of systemic chemotherapy is required for massive ascites or poor performance status. The natural history, diagnosis and treatment of PDAC with peritoneal dissemination have not been fully investigated. We systematically reviewed published information on the clinical diagnosis and treatment of PDAC with peritoneal dissemination using the PubMed database (2000-2020) and provided recommendations in response to clinical questions. This guideline was created according to the "Minds Clinical Practice Guideline Development Guide 2017". The literature quality and body of evidence were evaluated with the GRADE System and classified into four levels ("strong", "medium", "weak", "very weak"). The strength of each final recommendation was decided by a vote of committee members based on the GRADE Grid method. These guidelines address three subjects: diagnostic, chemotherapeutic, and surgical approaches. They include nine clinical questions and statements with recommendation strengths, evidence levels, and agreement rates, in addition to one "column". This is the English synopsis of the 2021 Japanese clinical practice guideline for PDAC with peritoneal dissemination. It summarizes the clinical evidence for the diagnosis and treatment of PDAC with peritoneal dissemination and provides future perspectives.

Patients with peritoneal dissemination (PD) caused by abdominal malignancies are often associated with massive ascites, which shows extremely dismal prognosis because of the discontinuation of systemic chemotherapy mostly due to poor performance status. Many treatment methods, such as simple drainage, peritoneovenous shunting (PVS) and cell-free and concentrated reinfusion therapy (CART), have been used for symptom relief. However, the clinical efficacies of these methods have not been fully investigated yet. Recently, we developed the Clinical Practice Guideline for PD caused by various malignancies according to "Minds Clinical Practice Guideline Development Guide 2017". In this guideline, we systematically reviewed information on clinical diagnosis and treatments for PD using PubMed databases (2000 - 2020), and clarified the degree of recommendation for clinical questions (CQ). The evidence level was divided into groups by study design and quality. The literature level and a body of evidence were evaluated in reference to the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. Based on the results of systematic review, the strength of the recommendations was evaluated at a consensus meeting of the Guideline Committee. This is the English synopsis of the part of treatment of malignant ascites in Clinical Practice Guideline for PD, 2021 in Japanese. The guidelines summarize the general aspect of the treatment of malignant ascites and statements with recommendation strengths, evidence levels, agreement rates and future perspective for four raised clinical questions.

The implication of IL-6 in the invasiveness and chemoresistance of ovarian cancer cells. Systematic review of its potential role as a biomarker in ovarian cancer patients.
Interleukin 6 (IL-6) is a pleiotropic cytokine that is strongly implicated in the development and progression of ovarian cancer. The most recognized actions of IL-6 in ovarian cancer (OC) cells are the induction of cell proliferation and inhibition of cell apoptosis. Equally important is its ability to enhance the migratory and invasive potential of OC cells. Moreover, the increased expression and secretion of this cytokine positively correlates with OC cell chemoresistance. Elevated concentrations of IL-6 are observed in the serum and ascites of ovarian cancer patients. Thus, its level is discussed in the literature as a potential biomarker that can help to discriminate malignant and nonmalignant ovarian tumors and allow for the prediction of the chemotherapy response. The importance of IL-6 in ovarian cancer is proved by the fact that this cytokine is a potential target to anti-cancer therapy. This review is divided into two parts. The first summarizes the general biological activity of IL-6, and overviews its impact on OC cells, as well as discusses the current proposition of IL-6 inclusion in combination of anti-OC therapy. The second part is a systematic review of IL-6 as a possible biomarker in ovarian cancer patients.

Meta-Analysis
BACKGROUND AND AIMS
The existing evidence has indicated that hyperthermia ablation (HA) and HA combined with transarterial chemoembolization (HATACE) are the optimal alternative to surgical resection for patients with hepatocellular carcinoma (HCC) in the COVID-19 crisis. However, the evidence for decision-making is lacking in terms of comparison between HA and HATACE. Herein, a comprehensive evaluation was performed to compare the efficacy and safety of HATACE with monotherapy.
MATERIALS AND METHODS
Worldwide studies were collected to evaluate the HATACE regimen for HCC due to the practical need for global extrapolation of applicative population. Meta-analyses were performed using the RevMan 5.3 software (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark).
RESULTS
Thirty-six studies involving a large sample of 5036 patients were included finally. Compared with HA alone, HATACE produced the advantage of 5-year overall survival (OS) rate (OR:1.90; 95%CI:1.46,2.46; p < 0.05) without increasing toxicity (p ≥ 0.05). Compared with TACE alone, HATACE was associated with superior 5-year OS rate (OR:3.54; 95%CI:1.96,6.37; p < 0.05) and significantly reduced the incidences of severe liver damage (OR:0.32; 95%CI:0.11,0.96; p < 0.05) and ascites (OR:0.42; 95%CI:0.20,0.88; p < 0.05). Subgroup analysis results of small (≤3 cm) HCC revealed that there were no significant differences between the HATACE group and HA monotherapy group in regard to the OS rates (p ≥ 0.05).
CONCLUSIONS
Compared with TACE alone, HATACE was more effective and safe for HCC. Compared with HA alone, HATACE was more effective for non-small-sized (>3 cm) HCC with comparable safety. However, the survival benefit of adjuvant TACE in HATACE regimen was not found for the patients with small (≤3 cm) HCC.

Survival in Advanced-Stage Epithelial Ovarian Cancer Patients with Cardiophrenic Lymphadenopathy Who Underwent Cytoreductive Surgery: A Systematic Review and Meta-Analysis.
PURPOSE
To evaluate the clinical outcomes of enlarged cardiophrenic lymph node (CPLN) in advanced-stage epithelial ovarian cancer (AEOC) patients who underwent cytoreductive surgery.
METHODS
The Embase, Medline, Web of Science, Cochrane Library, and Google Scholar databases were searched for articles from the database inception to June 2021. Meta-analysis was conducted to determine the prognostic impact of surgical outcome, postoperative complication, and survival using random-effects models.
RESULTS
A total of 15 studies involving 727 patients with CPLN adenopathy and 981 patients without CPLN adenopathy were included. The mean size of preoperative CPLN was 9.1± 3.75 mm. Overall, 82 percent of the resected CPLN were histologically confirmed pathologic nodes. Surgical outcomes and perioperative complications did not differ between both groups. The median OS time was 42.7 months (95% CI 10.8-74.6) vs. 47.3 months (95% CI 23.2-71.2), in patients with and without CPLN adenopathy, respectively. At 5 years, patients with CPLN adenopathy had a significantly increased risk of disease recurrence (HR 2.14, 95% CI 1.82-2.52, < 0.001) and dying from the disease (HR 1.74, 95% CI 1.06-2.86, = 0.029), compared with those without CPLN adenopathy. CPLN adenopathy was significantly associated with ascites (OR 3.30, 95% CI 1.90-5.72, < 0.001), pleural metastasis (OR 2.58, 95% CI 1.37-4.82, = 0.003), abdominal adenopathy (OR 2.30, 95% CI 1.53-3.46, < 0.001) and extra-abdominal metastasis (OR 2.30, 95% CI 1.61-6.67, = 0.001).
CONCLUSIONS
Enlarged CPLN in preoperative imaging is highly associated with metastatic involvement. Patients with CPLN adenopathy had a lower survival rate, compared with patients without CPLN adenopathy. Further randomized controlled trials should be conducted to definitively demonstrate whether CPLN resection at the time of cytoreductive surgery is beneficial.

Review
BACKGROUND
Malignancy-related ascites (MRA) is one of the symptoms causing discomfort in advanced cancer patients. Cell-free and concentrated ascites reinfusion therapy (CART) is one of the palliative treatments widely conducted in Japan only.
METHODS
A systematic review following a meta-analysis of CART was performed. The efficiency and adverse events were evaluated.
RESULTS
A total of 2567 patients and 6013 procedures of CART were identified in this study. The mean volume of MRA collected was 4.29 (95% confidence interval (CI) 3.47-5.11) L, and the volume reinfused after concentrating was 0.49 (95% CI 0.39-0.60) L. A total of 86.1 (95% CI 77.1-95.2) g protein and 42.9 (95% CI 36.0-50.0) g albumin was reinfused. The mean time to the next paracentesis was 20.7 (95% CI 15.6-25.8) days. The body weight was reduced by 3.38 (95% CI 1.90-4.86; < 0.01) kg, and abdominal circumference was reduced by 7.86 (95% CI 6.58-9.14; < 0.001) cm. Serum albumin increased an average of 0.14 (95% CI -0.01-0.28; = 0.07) mg/dL the day after CART. Abdominal distension, dyspnea, and fatigue were alleviated by 6.0 (95% CI 5.59-6.51), 2.66 (95% CI 2.05-3.28), and 2.64 (95% CI 1.86-3.42) points using a numerical rating scale system ranging from 0 to 10. Overall, 17% (95% CI 0.03-0.31%) of patients had improved performance status after CART. Significant body temperature elevation was observed, at an average of 0.4 °C (95% CI 0.18-0.62 °C).
CONCLUSIONS
CART might be a safe and effective palliative therapy in MRA and further clinical trials are necessary.

Meta-Analysis Review
BACKGROUND
Severe dengue is a life-threatening complication; rapid identification of these cases, followed by adequate management is crucial to improve the clinical prognosis. Therefore, this study aimed to identify risk factors and predictors of severe dengue.
METHODS
A literature search for studies reporting risk factors of severe dengue among individuals with dengue virus infection was conducted in PubMed, Scopus and Web of Science database from inception to December 31, 2020. Pooled odds ratios (ORs) for patients' demographic characteristics, co-morbidities, and warning signs were estimated using an inverse variance heterogeneity model.
RESULTS
We included 143 articles in the meta-analysis from a total of 13 090 articles retrieved from the literature search. The risk factors of severe dengue were: being a child [OR = 1.96; 95% confidence interval (CI): 1.22-3.13], secondary infection (OR = 3.23; 95% CI: 2.28-4.57), and patients with pre-existing diabetes (OR = 2.88; 95% CI: 1.72-4.81) and renal disease (OR = 4.54; 95% CI: 1.55-13.31). Warning signs strongly associated with severe disease were increased haematocrit with a concurrent decrease in platelet count (OR = 5.13; 95% CI: 1.61-16.34), abdominal pain (OR = 2.00; 95% CI: 1.49-2.68), lethargy (OR = 2.73; 95% CI: 1.05-7.10), vomiting (OR = 1.80; 95% CI: 1.43-2.26), hepatomegaly (OR = 5.92; 95% CI: 3.29-10.66), ascites (OR = 6.30; 95% CI: 3.75-10.60), pleural effusion (OR = 5.72; 95% CI: 3.24-10.10) and melena (OR = 4.05; 95% CI: 1.64-10.00).
CONCLUSIONS
Our meta-analysis identified children, secondary infection, diabetes and renal disease(s) as important predictors of severe dengue. Our finding also supports the predictive ability of the WHO warning signs to identify severe dengue. These findings are useful for clinicians to identify severe dengue for management and timely interventions.

Meta-Analysis
Ascites is the most common presentation of decompensated liver cirrhosis. It is treated with therapeutic paracentesis which is associated with several complications. The role of human albumin in patients with cirrhotic ascites remains elusive and has been extensively studied with conflicting results. Thus, in order to fully appraise the available data we sought to perform this systematic review and meta-analysis. Herein we included studies comparing the efficacy and safety of human albumin comparing with other volume expanders and vasoactive agents in patients undergoing paracentesis in cirrhotic ascites. Odds ratio (OR) and mean difference (MD) were used to estimate the outcome with a 95% confidence interval (CI). Albumin use reduced the odds of paracentesis induced circulatory dysfunction (PICD) by 60% (OR 0.40, 95% CI 0.27-0.58). While performing subgroup analysis, albumin use lowered the odds of PICD significantly (OR 0.34, 95% CI 0.22-0.52) in comparison to other colloid volume expanders, but did not lower the odds of PICD in comparison to vasoconstrictor therapy (OR 0.93, 95% CI 0.35-2.45). Albumin was associated with a statistically significant lower incidence of hyponatremia (OR 0.59, 95% CI 0.39-0.88). Albumin did not reduce the overall mortality, readmission rate, recurrence of ascites, mean arterial pressure, incidence of renal impairment, hepatic encephalopathy, and gastrointestinal (GI) bleeding. Thus, treatment with albumin in cirrhotic ascites reduced PICD and hyponatremia although there was no benefit in terms of mortality, readmission rate, recurrence of ascites, hepatic encephalopathy, and GI bleeding.

Meta-Analysis Review
BACKGROUND
Many prognostic models for Hepatocellular Carcinoma (HCC) have been developed to inform patients and doctors about individual prognosis. Previous reviews of these models were qualitative and did not assess performance at external validation. We assessed the performance of prognostic models for HCC and set a benchmark for biomarker studies.
METHODS
All externally validated models predicting survival for patients with resected HCC were systematically reviewed. After selection, we extracted descriptive statistics and aggregated c-indices using meta-analysis.
RESULTS
Thirty-eight validated prognostic models were included. Models used on average 7 (IQR:4-9) prognostic factors. Tumor size, tumor number, and vascular invasion were almost always included. Alpha-fetoprotein (AFP) was commonly incorporated since 2007. Recently, the more subjective items ascites and encephalopathy have been dropped. Eight established models performed poor to moderate at external validation, with a pooled C-index below 0.7; including the Barcelona Clinic Liver Cancer (BCLC) system, the American Joint Committee on Cancer (AJCC) 7th edition, the Cancer of the Liver Italian (CLIP) Program, and the Japan Integrated Staging (JIS) score. Out of 24 prognostic models predicting OS, only 6 (25%) had good performance at external validation with pooled C-indices above 0.7; the Li-post (0.77), Li-OS (0.74), Yang-pre (0.74), Yang-post (0.76), Shanghai-score (0.70), and Wang-nomogram (0.71). Models improved over time, but overall performance and study quality remained low.
CONCLUSIONS
Six validated prognostic models demonstrated good performance for predicting survival after resection of HCC. These models can guide patients and doctors and are a benchmark for future models incorporating novel biomarkers.

Meta-Analysis
Introduction and objectives It has been suggested that albumin administration could alter the natural history of cirrhosis, and also, that long-term treatment with albumin might be associated with improvement in survival, control of ascites, reduction in the incidence bacterial infections, renal dysfunction, hepatic encephalopathy (HE) and hyponatremia, as well as reduction in length of hospitalization in patients with cirrhosis and ascites. The objective of the present study is to evaluate the role of albumin in the management of HE. Materiales and methods:: This is a systematic review of randomized controlled trials that evaluated the use of albumin in adult patients with cirrhosis and HE. The search for eligible studies was performed in MEDLINE, EMBASE, and Cochrane CENTRAL databases until June 2020. The outcomes of interest were the complete reversal of HE and mortality. Meta-analysis was performed using the random effects model, through the Mantel-Haenszel method. Results: This systematic review was registered at the PROSPERO platform (CRD42020194181). The search strategy retrieved 1,118 articles. After reviewing titles and abstracts, 24 studies were considered potentially eligible, but 22 were excluded after full-text analysis. Finally, 2 studies were included. In the meta-analysis, albumin was associated to significant lower risks of persistent HE (risk ratio - RR = 0.60; 95% confidence interval - CI = 0.38-0.95, p = 0.03) and mortality (RR = 0.54; 95% CI = 0.33-0.90, p = 0.02). Conclusion: Albumin administration improves HE and reduces mortality in patients with cirrhosis and HE.
