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
Is there a correlation of positive peritoneal washing cytology during interval debulking surgery on the survival outcomes of ovarian cancer patients? A systematic review and meta-analysis of the literature.
OBJECTIVE
The aim of the present study was to evaluate the prognostic impact of peritoneal washing cytology (PWC) on progression-free (PFS) and overall survival (OS) of patients undergoing interval debulking surgery (IDS) after neoadjuvant chemotherapy (NACT) for ovarian cancer (OC).
METHODS
We systematically searched Medline (1966-2020), Scopus (2004-2020), EMBASE (1980-2020), Cochrane Central Register of Controlled Trials CENTRAL (1999-2020), Clinicaltrials.gov (2008-2020) and Google Scholar (2004-2020). All the studies that investigated the correlation of peritoneal washing cytology with survival outcomes of patients undergoing interval debulking for ovarian cancer, were finally included in the present meta-analysis.
RESULTS
A total of 7 retrospective studies were included, comprising 907 patients, of whom 535 had positive peritoneal washing cytology on interval debulking surgery. The methodological quality of the included studies was assessed as moderate, primarily due to the lack of data referring to the adequacy of the follow-up of patients and secondarily due the lack of comparability of patients. Progression - free survival was significantly better in the negative peritoneal cytology group (HR 2.07, 95% CI 1.73, 2.48 respectively), however, overall survival did not reach a significant difference among the two groups (HR 1.90, 95% CI 0.99, 3,65, p = 0.052).
CONCLUSIONS
Our data support a negative correlation between positive peritoneal washing cytology at interval debulking surgery and the survival of 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.

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
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
To evaluate comparative outcomes of laparoscopic versus open hepatectomy for malignant liver tumours in elderly patients. A systematic online search was conducted using the following databases: PubMed, Scopus, Cochrane database, The Virtual Health Library, Clinical trials.gov, and Science Direct. Comparative studies comparing laparoscopic (LH) versus open hepatectomy (OH) for both primary and metastatic malignant liver tumours in the elderly were included. Total operative time (minutes), need to perform Pringle's manoeuvre, blood loss (ml), the requirement for blood transfusion intra-operatively/post-operatively, post-operative complications, r0 resection rate, specimen resection margin (mm), re-operation rate, length of hospital stay (LOS), and 90-day mortality were the evaluated outcome parameters. Twelve studies reporting a total number of 1762 patients who underwent laparoscopic (n = 831) or open (n = 931) hepatectomy were included. OH group was associated with a significantly higher overall number of post-operative complications compared to LH (P = 0.00001). Complications such as post-operative liver failure (P = 0.02), ascites formation (P = 0.002), surgical site infection (P = 0.02), blood loss (P = 0.03), blood transfusion rate (P = 0.05), and LOS (P = 0.00001) were significantly higher in the OH group when compared to LH. There was no significant difference between the two groups in terms of total operative time (P = 0.53), bile leak (P = 0.12), r0 resection rate (P = 0.36), re-operation (P = 0.70), and 90-day mortality (P = 0.11). Laparoscopic liver resections are safe with at least equal or superior peri-operative outcomes in the elderly population, although available data regards mainly the results of minor resections. Laparoscopic major resections in the elderly population should be carefully evaluated and preferably performed in expert centres.

World Journal of Gastrointestinal... Jun 2021Chylous ascites is a rare complication in colorectal surgery with limited evidence.
BACKGROUND
Chylous ascites is a rare complication in colorectal surgery with limited evidence.
AIM
To systematically review all available evidence to describe the incidence, clinical presentation, risk factors and management strategies.
METHODS
The systematic review was performed through PubMed, MEDLINE, EMBASE and Cochrane and cross-checked up to November 2020. The data collated included: Demographics, indications (benign malignant), site of disease, surgical approach, extent of lymphadenectomy, day to and method of diagnosis of chylous ascites and management strategies.
RESULTS
A total of 28 studies were included in the final analysis (426 cases). Patient age ranged from 31 to 89 years. All except one case were performed for malignancy. Of the 426 cases, 195 were right-colonic, 121 left-colonic, 103 pelvic surgeries and 7 others. The majority were diagnosed during the same inpatient stay by recognition of typical drain appearance and increased volume. Three cases were diagnosed during outpatient visits with increased abdominal distention and subsequently underwent paracentesis. Most cases were managed successfully non-operatively (fasting with prolonged drainage, total parenteral nutrition, somatostatin analogues or a combination of these). Only three cases required surgical intervention after failing conservative management and subsequently resolved completely. Risk factors identified include: Right-colonic surgery/ tumour location, extent of lymphadenectomy and number of lymph nodes harvested.
CONCLUSION
Chylous ascites after colorectal surgery is a relatively rare complication. Whilst the majority of cases resolved without surgical intervention, preventative measures should be undertaken such as meticulous dissection and clipping of lymphatics during lymphadenectomy to prevent morbidity.

In the present study, we aimed to clarify features of carcinomatous cirrhosis from breast cancer presenting as refractory transudate ascites and acute liver failure. In our systematic literature review, we identified 26 studies and 31 cases including our case of this rare condition. Our patient was a 49-year-old woman with a history of ascites and liver failure for the past 4 years and currently being treated for invasive ductal breast cancer. On radiography, she had occult liver metastases that were confirmed using laparoscopic liver biopsy. In the 31 cases, data on the reported year, age, type of primary breast cancer, time from breast cancer diagnosis, presence of ascites and/or varices, liver biopsy, diagnostic modalities, outcomes, and survival were documented and analyzed. All cases were reported during 1984-2020, with a mean patient age of 52.9 years. Eighteen patients (58.1%) were diagnosed with ductal breast cancer. Twenty-two patients (70.9%) had ascites. All patients had gradual progression to liver dysfunction. The following tests were performed: computed tomography (77.4%); ultrasound (58.0%); liver biopsy (100%); postmortem biopsy (35.5%), transjugular liver biopsy (32.3%), and laparoscopic liver biopsy (3.2%). Outcomes were reported for 29 patients, of whom 24 (82.3%) died after 1 day to 16 months. Invasive ductal carcinoma was the most common histological type; however, invasive lobular carcinoma was more frequent (32.3%) than its reported incidence in the breast. Carcinomatous cirrhosis has poor prognosis at relatively rash and is difficult to diagnose with usual modalities. It may be associated with E-cadherin loss or CD44 pronouncement.
