BACKGROUND
Gastric cancer is the fifth most common cancer and the third leading cause of cancer-related death worldwide. Advanced gastric cancer (AGC) is associated with significant morbidity and mortality and is commonly accompanied by a variety of distressing symptoms. Current National Comprehensive Cancer Network (NCCN) guidelines recommend palliative treatment modalities for patients with AGC and the treatment of AGC patients should be influenced by palliative care principles. The objective of this systematic review was to explore the published literature on palliative interventions for patients with AGC.
METHODS
We performed a systematic literature search to identify English language studies that investigated interventions to improve or treat the symptoms caused by AGC using PubMed, Embase, and Cochrane Library databases from January 1, 2010 to August 18, 2022. Two independent reviewers performed title and abstract review, followed by full-text review and data abstraction. Overall study quality and risk of bias was assessed using published quality assessment tools.
RESULTS
We identified 10,364 studies and included 66 studies published between 2010 and 2022 for final review. Among the studies, quality of life (QoL) metrics were most commonly a secondary outcome. Twenty-three studies addressed the palliative management of bleeding with the use of radiation therapy, surgery, arterial embolization, chemotherapy, or endoscopic interventions. Twenty-two studies addressed the management of obstructive symptoms with endoscopic stenting or surgical interventions. Most of these studies were of moderate quality and included well characterized outcomes focused on symptom reduction. Five studies assessed palliative modalities to reduce the symptomatic burden of intraabdominal ascites; these studies were less well characterized, and on average low quality. Fifteen studies of mixed quality assessed QoL for patients with AGC, with only one study evaluating specialty palliative care consultation. No studies outlined the prevalence or practices of advanced care planning in this patient population.
CONCLUSIONS
Patients with AGC undergo a variety of interventions aimed at palliating the symptoms associated with their diagnosis and improving their QoL. Future research on palliative interventions for patients with AGC should utilize qualitative methodologies to measure outcomes related to symptom management and QoL, further explore the patient experience of living with AGC, and delineate best practices for advanced care planning in this population.

Meta-Analysis
Pseudocirrhosis is a clinical and radiological entity mimicking liver cirrhosis in patients without a history of chronic liver disease. We performed a systematic review and meta-analysis of the current literature to evaluate the state-of-the-art and investigate the epidemiology and clinical features of pseudocirrhosis. We searched PubMed, Web of Science and Scopus for literature published until February 28, 2022. We included in the final analysis 62 articles (N = 389 patients): 51 case reports (N = 64 patients), 5 case series (N = 35 patients) and 6 observational studies (N = 290 patients). About 80% of patients included in the case reports and case series had breast cancer. Most patients had at least one clinical sign of portal hypertension and ascites was the most common clinical manifestation of portal hypertension. The median time from pseudocirrhosis to death was 2 months (IQR 1-7 months). Alkylating agents and antimitotics were the most common classes of anticancer drugs reported in our study population. Notably, about 70% of patients received three or more anticancer drugs. Finally, pseudocirrhosis is a condition that occurs in patients with hepatic metastases and may have a negative impact on survival and clinical management of patients because of the potential development of portal hypertension and its complications.

Review
BACKGROUND
Ovarian malignant mesoderm mixed tumor (OMMMT) is a rare clinical entity. To provide reference for the treatment and prognosis of OMMMT, we analyzed the clinical features, pathology and molecular biology characteristic of published cases.
METHODS
The English and Chinese reported cases of OMMMT were selected from PubMed, Clinical Trials.gov and CNKI database from 2000 to December 15th, 2021 following the PRISMA guidelines.
RESULTS
A total of 63 literatures including 199 OMMMT cases were included. The average age of patients at diagnosis was 56.46 years, the highest incidence age was 60-65 years, and 82% of them were menopausal women. Most patients were diagnosed in FIGO III stage (59.64%). The most common symptom of OMMMT was abdominal pain (60.5%). 61.6% of patients were accompanied by ascites, while ascites was not associated with metastatic tumor and local recurrence. The CA125 of 88.68% patients increased. The most common reported carcinomatous component and sarcomatous component were serous adenocarcinoma (44.96%) and chondrosarcoma (24.81%), respectively. Initial treatment included surgery (94.97%) and taxanes-based (55.10%) or platinum-based (85.71%) chemotherapy regimens. The median survival time of patients was 20 months. Heterologous sarcoma component did not shorten life expectancy. The optimal ovarian tumor cell debulking surgery (OOTCDS), radiotherapy and chemotherapy could significantly prolong the median survival time of patients. Furthermore, platinum drugs could significantly prolong the survival time after comparing various chemotherapy schemes. Besides, the combination of platinum and taxanes was therapeutically superior to the combination of platinum and biological alkylating agents.
CONCLUSION
The OOTCDS and platinum-based chemotherapy regimen can improve the prognosis of OMMMT. Targeted therapy might become a new research direction in the future. Since the elderly patients are the majority, the toxicity of new drugs on the elderly patients is more noteworthy.

Malignant ascites (MA) is a common complication of terminal cancer, which seriously affects the life quality and prognosis of patients. Both hyperthermic intraperitoneal chemotherapy (HIPEC) and traditional Chinese medicine (TCM) preparations have achieved significant efficacy in the treatment of MA. The treatment strategy of TCM combined with HIPEC has been gradually promoted and applied in China. The purpose of this systematic review and meta-analysis was to assess the efficacy of TCM combined with HIPEC in the treatment of MA. Randomized controlled trials (RCTs) of TCM combined with HIPEC for MA were searched from seven electronic databases. Two researchers used the Cochrane Collaboration's tool to assess the risk of bias. Excel 2019 was used to establish a database for information extraction, RevMan 5.4 software was used to analyze the included test data, and STATA v16.0 was used to conduct Egger's test to further detect publication bias. A total of 19 studies involving 1,504 patients were included in this meta-analysis. The results showed that compared with the single use of HIPEC, TCM combined with HIPEC could significantly improve the clinical efficacy (RR = 1.51, 95% CI [1.40, 1.63], < 0.00001) and karnofsky performance status (KPS) score (MD = 8.16, 95% CI [6.46, 9.85], < 0.00001), reduce the ascites volume (MD = -156.98, 95% CI [-213.71, -100.25], < 0.00001). However, there was no statistical significance in reducing abdominal circumference between TCM combined with HIPEC and HIPEC alone (MD = -1.8, 95% CI [-4.57, -0.97], = 0.2). This study found that TCM combined with HIPEC had a beneficial therapeutic effect on MA. However, more standard, double-blind, multicenter RCTs are needed to further confirm the efficacy of TCM combined with HIPEC in the treatment of MA. https://www.crd.york.ac.uk/, identifier CRD42022319993.

Review
The presence of ascites is a common clinical presentation in gynecologic oncology patients. Hemorrhagic ascites (HA) due to endometriosis is a rare presentation that can be easily misdiagnosed as ovarian malignancies. The present study aims to update the currently available knowledge on the characteristics of patients presenting with HA due to endometriosis. A systematic search was conducted for articles published from January 2000 to July 2020 using the Medline, Scopus, and Google Scholar databases along with the references of the full-text articles retrieved. Papers describing cases of women over 18 years with or without previous history of endometriosis were assessed. Only cases with histologically proven hemorrhagic ascites of endometriosis origin were included. Twenty-nine studies (27 case reports and two case series) comprising 32 patients were evaluated. The mean patients' age was 32 years, while six of the patients had a previous history of endometriosis. The mean amount of drained ascitic fluid was 4,200 mL, whereas three patients underwent thoracentesis due to pleural effusions. The treatment options included not only medical but also surgical therapies. Fertility preservation was achieved in 27 patients, while two of them achieved pregnancy with in vitro fertilization (IVF) techniques. Endometriosis-related hemorrhagic ascites is a relatively rare expression of the disease. Endometriosis-related hemorrhagic ascites should be considered in the differential diagnosis (DD) of women with ascites and clinical suspicion of endometriosis. The available literature is limited to case reports and case series and thus indicates further research in the field to decode the pathophysiology of the disease and decide on the optimal treatment.

BACKGROUND
Radiofrequency ablation (RFA) has been used to treat various abdominal tumors including pancreatic tumors. Multiple approaches such as laparoscopic, open, and percutaneous have been used for pancreatic tissue ablation. More recently, endoscopic ultrasound (EUS)-guided RFA has emerged as a new technique for pancreatic tissue ablation. The role of EUS-RFA in management of pancreatic lesions is still not well-established. In this study, our aim is to assess efficacy and safety of EUS-RFA for management of pancreatic lesions.
METHODS
MEDLINE, Scopus, and Cochrane Library databases were searched to identify studies reporting EUS-RFA of pancreatic lesions with outcomes of interest. Studies with <5 patients were excluded. Clinical success was defined as symptom resolution, decrease in tumor size, and/or evidence of necrosis on radiologic imaging. Efficacy was assessed by the pooled clinical response rate whereas safety was assessed by the pooled adverse events rate. Heterogeneity was assessed using I. Pooled estimates and the 95% CI were calculated using random-effect model.
RESULTS
Ten studies (5 retrospective and 5 prospective) involving 115 patients with 125 pancreatic lesions were included. 152 EUS-RFA procedures were performed. The lesions comprised of 37.6% non-functional neuroendocrine tumors (NFNETs), 15.4% were insulinomas, 26.5% were pancreatic cystic neoplasms (PCNs), and 19.7% were pancreatic adenocarcinomas. The majority were present in the pancreatic head (40.2%), 38.3% in the body, 11.2% in the tail, and 10.3% in the uncinate process. Pooled overall clinical response rate was 88.9% (95% CI: 82.4-93.7, I=38.1%). Pooled overall adverse events rate was 6.7% (95% CI: 3.4-11.7, I=34.0%). The most common complication was acute pancreatitis (3.3%) followed by pancreatic duct stenosis, peripancreatic fluid collection, and ascites (2.8%) each. Only one case of perforation was reported with pooled rate of (2.1%).
DISCUSSION
This study demonstrates that EUS-RFA is an effective treatment modality for pancreatic lesions, especially functional neuroendocrine tumors such as insulinomas.

Liver Stiffness on Magnetic Resonance Elastography and the MEFIB Index and Liver-Related Outcomes in Nonalcoholic Fatty Liver Disease: A Systematic Review and Meta-Analysis of Individual Participants.
BACKGROUND & AIMS
Magnetic resonance elastography (MRE) is an accurate biomarker of liver fibrosis; however, limited data characterize its association with clinical outcomes. We conducted an individual participant data pooled meta-analysis on patients with nonalcoholic fatty liver disease to evaluate the association between liver stiffness on MRE and liver-related outcomes.
METHODS
A systematic search identified 6 cohorts of adults with nonalcoholic fatty liver disease who underwent a baseline MRE and were followed for hepatic decompensation, hepatocellular carcinoma, and death. Cox and logistic regression were used to assess the association between liver stiffness on MRE and liver-related outcomes, including a composite primary outcome defined as varices needing treatment, ascites, and hepatic encephalopathy.
RESULTS
This individual participant data pooled meta-analysis included 2018 patients (53% women) with a mean (± standard deviation) age of 57.8 (±14) years and MRE at baseline of 4.15 (±2.19) kPa, respectively. Among 1707 patients with available longitudinal data with a median (interquartile range) of 3 (4.2) years of follow-up, the hazard ratio for the primary outcome for MRE of 5 to 8 kPa was 11.0 (95% confidence interval [CI]: 7.03-17.1, P < .001) and for ≥ 8 kPa was 15.9 (95% CI: 9.32-27.2, P < .001), compared with those with MRE <5 kPa. The MEFIB index (defined as positive when MRE ≥3.3 kPa and Fibrosis-4 ≥1.6) had a robust association with the primary outcome with a hazard ratio of 20.6 (95% CI: 10.4-40.8, P < .001) and a negative MEFIB had a high negative predictive value for the primary outcome, 99.1% at 5 years. The 3-year risk of incident hepatocellular carcinoma was 0.35% for MRE <5 kPa, 5.25% for 5 to 8 kPa, and 5.66% for MRE ≥8 kPa, respectively.
CONCLUSION
Liver stiffness assessed by MRE is associated with liver-related events, and the combination of MRE and Fibrosis-4 has excellent negative predictive value for hepatic decompensation. These data have important implications for clinical practice.

Meta-Analysis
OBJECTIVE
Advances in ovarian cancer cytoreductive surgery have enabled more extensive procedures to achieve maximal cytoreduction but with a consequent increase in postoperative morbidity and mortality. The aim of this study was to evaluate factors for postoperative morbidity after extensive cytoreductive surgery for primary epithelial ovarian cancer (EOC), particularly those which may be modifiable.
METHODS
Electronic databases were searched. Meta-analysis was conducted using random-effects models.
RESULTS
Fifteen relevant studies, involving 15,325 ovarian cancer patients, were included in this review. Severe 30-day postoperative complications occurred in 2,357 (15.4%) patients. The postoperative mortality rate was 1.92%. Meta-analysis demonstrated that patient with following risk factors; age (p<0.001), Eastern Cooperative Oncology Group score >0 (p=0.001), albumin level <3.5 g/dL (p<0.001), presence of ascites on CT scan (p=0.013), stage IV disease (p<0.001) and extensive surgical procedure (p<0.001) has a significantly increase risk of developing postoperative complications. Surgical procedures including peritonectomy (p=0.012), splenectomy (p<0.001) and colon surgery (p<0.001) were significant predictors for postoperative complications. Moreover, we found that patients who received neoadjuvant chemotherapy followed by interval debulking surgery (NACT-IDS) had a lower risk of developing severe complications compared to those who underwent primary debulking surgery (PDS) (p<0.001).
CONCLUSION
Our study demonstrated that patient performance status and hypoalbuminemia were the only significant adjustable preoperative risk factors associated with postoperative complications. Patients who underwent NACT-IDS had a lower risk of developing severe complications compared to PDS.

Meta-Analysis
BACKGROUND
Changes in endothelial function are implicated in the spread of tuberculosis (TB). Studies suggest a role for the vascular endothelial growth factor (VEGF) in TB-related endothelial function changes. However, the findings of studies investigating the VGEF profile in TB are not consistent, and no formal systematic review and meta-analysis exists summarizing these studies.
METHODS
We did a meta-analysis of studies assessing VEGF levels in patients with TB. A systematic search on June 25, 2021, was conducted for eligible studies that made VEGF measurements in an unstimulated sample, e.g., a blood fraction (plasma or serum), cerebrospinal fluid (CSF), pleural effusion (PE), or bronchoalveolar lavage fluid, and ascites or pericardial fluid for patients with TB and controls without TB. Also, studies that made simultaneous measurements of VEGF in blood and PE or CSF in the same patients with TB were included. Longitudinal studies that provided these data at baseline or compared pre-post anti-tuberculosis treatment (ATT) levels of VEGF were included. The primary outcome was the standardized mean difference (SMD) of VEGF levels between the comparison groups.
RESULTS
52 studies were included in the meta-analysis. There were 1787 patients with TB and 3352 control subjects of eight categories: 107 patients with transudative pleural effusion, 228 patients with congestive heart failure (CHF)/chronic renal failure (CRF), 261 patients with empyema and parapneumonic effusion (PPE), 241 patients with cirrhosis, 694 healthy controls (with latent TB infection or uninfected individuals), 20 patients with inactive tuberculous meningitis (TBM), 123 patients with non-TBM, and 1678 patients with malignancy. The main findings are as follows: (1) serum levels of VEGF are higher in patients with active TB compared with healthy controls without other respiratory diseases, including those with latent TB infection or uninfected individuals; (2) both serum and pleural levels of VEGF are increased in patients with TPE compared with patients with transudative, CHF/CRF, or cirrhotic pleural effusion; (3) ascitic/pericardial fluid, serum, and pleural levels of VEGF are decreased in patients with TB compared with patients with malignancy; (4) pleural levels of VEGF are lower in patients with TPE compared with those with empyema and PPE, whereas serum levels of VEGF are not different between these patients; (5) both CSF and serum levels of VEGF are increased in patients with active TBM compared with controls, including patients with inactive TBM or non-TBM subjects; (6) post-ATT levels of VEGF are increased compared with pre-ATT levels of VEGF; and (7) the mean age and male percentage of the TB group explained large and total amount of heterogeneity for the meta-analysis of blood and pleural VEGF levels compared with healthy controls and patients with PPE, respectively, whereas these moderators did not show any significant interaction with the effect size for other analyses.
DISCUSSION
The important limitation of the study is that we could not address the high heterogeneity among studies. There might be unmeasured factors behind this heterogeneity that need to be explored in future research. Meta-analysis findings align with the hypothesis that TB may be associated with abnormal vascular function, and both local and systemic levels of VEGF can be used to trace this abnormality.

BACKGROUND
Cellular immunotherapy has become a new and promising treatment for patients with liver tumor. However, as most immune cells are delivered by intravenous injection, the effect is limited and is likely to produce systemic toxicity. Here, the objective was to investigate the efficacy and safety of cellular immunotherapy by local infusion, which seems to be a promising approach and has not been well-studied.
METHODS
The PubMed, Web of Science, Embase, and Cochrane Library databases were searched to obtain literature. The overall response rate (ORR), overall survival (OS) rates, and adverse events were investigated to evaluate the effectiveness and safety of locoregional therapy. The methodological quality of the articles was assessed using the methodological index for non-randomized studies (MINORS) score. The meta-analysis was performed using Stata 15.0.
RESULTS
The eligible 17 studies involved a total of 318 patients. The random-effects model demonstrated that the ORR of local cell infusion therapy was 48% (95% confidence interval [CI]: 26%-70%). The pooled OS rate was 94% (95% CI: 83%-100%) at 6 months, 87% (95% CI: 74%-96%) at 12 months, and 42% (95% CI: 16%-70%) at 24 months. Subgroup analyses suggested that minimally invasive treatment and absence of metastasis were significantly associated with better ORR. Fourteen studies reported a variety of adverse events related to cell therapy by local perfusion. The most common complications after regional infusion of immune cells were myelosuppression (66%), fever (50%), gastrointestinal toxicity (22%), hepatic dysfunction (15%), and pleural effusion and/or ascites (14%).
CONCLUSIONS
Immune cell therapy through local perfusion is effective for patients with liver cancer, with manageable toxicity. It demonstrates better prognosis when combined with minimally invasive therapy. Considering the potential limitations, more randomized controlled trials are needed to provide solid evidence for our findings.
