Meta-Analysis Review
Sarcopenia has been considered an adverse prognostic factor in cancer patients. Intramuscular adipose tissue content, as a new marker of sarcopenia, can effectively reflect skeletal muscle quality. The aim of this study was performed to evaluate the association between high intramuscular adipose tissue content (IMAC) and survival outcomes and postoperative complications in cancer patients. Specific databases, including the Web of Science, Embase and Web of Science, were systematically searched to identify relevant articles evaluating the prognostic value of IMAC in cancer patients. Hazard ratios (HRs) or odds ratios (ORs) with 95% confidence intervals (CIs) were utilized for comprehensive analysis. All data analyses were performed using STATA 12.0 software. A total of 25 studies from 24 articles including 5663 patients were enrolled in the study. Meta-analysis showed that high IMAC was associated with unfavourable overall survival (OS) (HR: 2.21, 95% CI: 1.70-2.86, P < 0.001), relapse-free survival (RFS) (HR: 1.51, 95% CI: 1.30-1.75, P < 0.001) and disease-specific survival (DSS) (HR: 1.64, 95% CI: 1.19-2.28, P = 0.003). Subgroup analysis revealed that high IMAC remained an adverse prognostic factor when stratified by different country, treatment methods, cancer type or analysis type. High IMAC had better predictive value for gallbladder carcinoma (GBC) (HR: 3.50, 95% CI: 1.98-6.17, P < 0.001), hepatocellular carcinoma (HCC) (HR: 1.84, 95% CI: 1.45-2.33, P < 0.001), pancreatic cancer (PC) (HR: 2.11, 95% CI: 1.67-2.66, P < 0.001) and colorectal cancer (CRC) (HR: 2.54, 95% CI: 1.27-5.10, P = 0.009). High IMAC was also identified as a significant risk factor for postoperative complications (OR: 2.05, 95% CI: 1.22-3.46, P = 0.007). High IMAC was associated with an adverse prognosis and an increased risk of postoperative complications in cancer patients. IMAC may be a good indicator of sarcopenia.

Meta-Analysis Review
OBJECTIVE
This systematic review aimed to investigate the association between dietary inflammatory potential and liver cancer to provide evidence regarding scientific dietary health education.
DESIGN
Systematic review and meta-analysis.
SETTING
A comprehensive literature review was conducted to identify case-control or cohort studies that involved dietary inflammation index (DII)/empirical dietary inflammation pattern (EDIP) and liver cancer in PubMed, EMBASE, Cochrane, and Web of Science databases. Using a combination of DII/EDIP and liver cancer as the search terms, the associations between DII/EDIP and liver cancer were then assessed.
PARTICIPANTS
Three case-control studies and two cohort studies were brought into the meta-analysis, with 225 713 enrolled participants.
RESULTS
Meta-analysis of categorical variables showed that DII/EDIP in the highest category increased the risk of liver cancer compared to DII/EDIP in the lowest category (relative risk (RR) = 2·35; 95 % CI 1·77, 3·13; = 0·000) and with low heterogeneity across studies (I = 40·8 %, = 0·119). Meta-analysis of continuous variables showed that significant positive association between liver cancer and DII/EDIP scores (RR = 1·24; 95 % CI 1·09, 1·40; = 0·001), and no heterogeneity (I² = 0·0 %, = 0·471). Stratified according to the study design, there was a significant positive association between liver cancer and DII/EDIP scores in both cohort studies (RR = 2·16; 95 % CI 1·51, 3·07; = 0·000) and case-control studies (RR = 2·75; 95 % CI 1·71, 4·41; = 0·000).
CONCLUSION
The higher the DII/EDIP score, the higher the risk of liver cancer. This finding may have prominent implications for the general population.

Meta-Analysis
BACKGROUND
Whether a transthoracic (TT) procedure by a thoracic surgeon or a transabdominal (TA) by a gastrointestinal surgeon is best for Siewert type II esophagogastric junction adenocarcinoma (EGJA) remains unknown. Survival and perioperative outcomes were compared between the two groups in this meta-analysis to clarify this argument.
METHODS
We searched 7 databases for eligible studies comparing TT and TA procedures for Siewert type II EGJA. The final analyzed endpoints included intraoperative and hospitalization outcomes, recurrence, complication, and survival.
RESULTS
Seventeen studies involving 10,756 patients met the inclusion criteria. The TA group had higher rates of overall survival (OS) (HR: 1.31 [1.20 ~ 1.44], p < 0.00001) and disease-free survival (DFS) (HR: 1.49 [1.24 ~ 1.79], p < 0.0001). The survival advantage of OSR and DFSR increased with time. Subgroup analysis of OS and DFS suggested that TA remained the preferred approach among all subgroups. More total/positive lymph nodes were retrieved, and fewer lymph node recurrences were found in the TA group. The analysis of perioperative outcomes revealed that the TA procedure was longer, had more intraoperative blood loss, and prolonged hospital stay. Similar R0 resection rates, as well as total recurrence, local recurrence, liver recurrence, peritoneal recurrence, lung recurrence, anastomosis recurrence and multiple recurrence rates, were found between the two groups. The safety analysis showed that the TT procedure led to more total complications, anastomotic leakages, cases of pneumonia, and cases of pleural effusion.
CONCLUSIONS
The TA procedure appeared to be a suitable choice for patients with Siewert type II EGJA because of its association with longer survival, fewer recurrences, and better safety.

BACKGROUND
Small retrospective series suggest that local consolidative treatment (LCT) may improve survival in oligometastatic pancreatic ductal adenocarcinoma (PDAC). However, no uniform definition of oligometastatic disease (OMD) in PDAC exists; this impedes meaningful conclusions.
PATIENTS AND METHODS
A systematic literature search using PubMed, Web of Science, and Cochrane CENTRAL registries for studies and protocols reporting on definitions and/or LCT of OMD in PDAC was performed. The primary endpoint was the definition of OMD. Levels of agreement were categorized as consensus (≥75% agreement between studies), fair agreement (50%-74%), and absent/poor agreement (<50%).
RESULTS
After screening of 5374 abstracts, the full text of 218 studies was assessed, of which 76 were included in the qualitative synthesis. The majority of studies were retrospective (n = 66, 87%), two were prospective studies and eight were study protocols. Studies investigated mostly liver (n = 38, 51%) and lung metastases (n = 15, 20%). Across studies, less than one-half (n = 32, 42%) reported a definition of OMD, while 44 (58%) did not. Involvement was limited to a single organ (consensus). Additional criteria for defining OMD were the number of lesions (consensus), metastatic site (poor agreement), metastatic size (poor agreement), treatment possibilities (poor agreement), and biomarker response (poor agreement). Liver OMD could involve three or fewer lesions (consensus) and synchronous disease (fair agreement), while lung metastases could involve two or fewer lesions and metachronous disease (consensus). The large majority of studies were at a high risk of bias or did not include any control groups.
CONCLUSION
Definitions of OMD were not used or varied widely between studies hampering across-study comparability and highlighting an unmet need for a consensus. The present study is part of a multistep process that aims to develop an interdisciplinary consensus on OMD in pancreatic cancer.

Meta-Analysis
Effect of intermittent Pringle maneuver on perioperative outcomes and long-term survival following liver resection in patients with hepatocellular carcinoma: a meta-analysis and systemic review.
BACKGROUND
Intermittent Pringle maneuver (IPM) is commonly used to control bleeding during liver resection. IPM can cause ischemia-reperfusion injury, which may affect the prognosis of patients with hepatocellular carcinoma (HCC). The present meta-analysis was conducted to evaluate the effect of IPM use on perioperative outcomes and long-term survival in patients with HCC.
METHODS
A systemic literature search was performed in the PubMed, Embase, Web of Science, and Cochrane Library databases to identify randomized controlled trials and retrospective studies that compared the effect of IPM with no Pringle maneuver during liver resection in patients with HCC. Hazard ratio (HR), risk ratio, standardized mean difference, and their 95% confidence interval (CI) values were calculated based on the type of variables.
RESULTS
This meta-analysis included nine studies comprising one RCT and eight retrospective studies and involved a total of 3268 patients. Perioperative outcomes, including operation time, complications, and length of hospital stay, except for blood loss, were comparable between the two groups. After removing the studies that led to heterogeneity, the results showed that IPM was effective in reducing blood loss. Five studies reported overall survival (OS) and disease-free survival (DFS) data and eight studies reported perioperative outcomes. No significant difference in OS and DFS was observed between the two groups (OS: HR, 1.01; 95% CI, 0.85-1.20; p = 0.95; DFS: HR, 1.01; 95% CI, 0.88-1.17; p = 0.86).
CONCLUSION
IPM is a useful technique to control blood loss during liver resection and does not affect the long-term survival of patients with HCC.

Meta-Analysis
BACKGROUND
RAS mutations affect prognosis in patients with metastatic colorectal cancer (mCRC) and have been identified as strong negative predictive markers for anti-epidermal growth factor receptor monoclonal antibody (anti-EGFR mAb) therapy, but many tumors containing wild-type RAS genes still do not respond to these therapies. Some additional biomarkers may have prognostic or predictive roles, but conclusions remain controversial.
METHODS
We performed a meta-analysis and systematic review of randomized controlled trials comparing anti-EGFR mAb therapy with alternative therapy that investigated the prognostic and predictive impact of additional biomarkers in RAS wild-type (wt) mCRC patients. Hazard ratios (HRs) and 95% confidence intervals (CIs) for progression-free survival (PFS) and overall survival (OS) and odds ratios (ORs) for objective response rate (ORR) were calculated. The prognostic value of biomarkers was investigated by separately pooling HR and OR for different treatment groups in an individual study. The predictive value was assessed by pooling study interactions between treatment effects and biomarker subgroups.
RESULTS
Thirty publications reporting on eighteen trials were selected, including a total of 13,507 patients. In prognostic analysis, BRAF mutations were associated with poorer PFS [HRs = 3.76 (2.47-5.73) and 2.69 (1.82-3.98)] and OS [HRs = 2.66 (1.95-3.65) and 2.45 (1.55-3.88)] in both the experimental and control arms; low miR-31-3p expression appeared to have longer PFS and OS. In terms of predictive effect, a lack of response to anti-EGFR therapy was observed in patients with BRAF mutant tumors (P < 0.01 for PFS). Patients with tumors with any mutation in the KRAS/NRAS/BRAF/PIK3CA gene also showed similar results compared with all wild-type tumors (P for PFS, OS, and ORR were < 0.01, < 0.01 and 0.01, respectively). While low miR-31-3p expression could predict PFS (P = 0.01) and OS (P = 0.04) benefit. The prognostic and predictive value regarding PIK3CA mutations, PTEN mutations or deletions, EGFR, EREG/AREG, HER2, HER3, and HER4 expression remains uncertain.
CONCLUSIONS
In RAS wt mCRC patients receiving EGFR-targeted therapy, BRAF mutation is a powerful prognostic and therapy-predictive biomarker, with no effect found for PIK3CA mutation, PTEN mutation or deletion, but the combined biomarker KRAS/NRAS/BRAF/PIK3CA mutations predict resistance to anti-EGFR therapy. Low miR-31-3p expression may have positive prognostic and therapy predictive effects. Evidence on the prognostic and predictive roles of EGFR and its ligands, and HER2/3/4 is insufficient.

BACKGROUND
Hepatocellular carcinoma is a malignant neoplasm of the liver and a leading cause of cancer-related deaths worldwide. The multimodal data combines several modalities, such as medical images, clinical parameters, and electronic health record (EHR) reports, from diverse sources to accomplish the diagnosis of liver cancer. The introduction of deep learning models with multimodal data can enhance the diagnosis and improve physicians' decision-making for cancer patients.
OBJECTIVE
This scoping review explores the use of multimodal deep learning techniques (i.e., combining medical images and EHR data) in diagnosing and prognosis of hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA).
METHODOLOGY
A comprehensive literature search was conducted in six databases along with forward and backward references list checking of the included studies. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) extension for scoping review guidelines were followed for the study selection process. The data was extracted and synthesized from the included studies through thematic analysis.
RESULTS
Ten studies were included in this review. These studies utilized multimodal deep learning to predict and diagnose hepatocellular carcinoma (HCC), but no studies examined cholangiocarcinoma (CCA). Four imaging modalities (CT, MRI, WSI, and DSA) and 51 unique EHR records (clinical parameters and biomarkers) were used in these studies. The most frequently used medical imaging modalities were CT scans followed by MRI, whereas the most common EHR parameters used were age, gender, alpha-fetoprotein AFP, albumin, coagulation factors, and bilirubin. Ten unique deep-learning techniques were applied to both EHR modalities and imaging modalities for two main purposes, prediction and diagnosis.
CONCLUSION
The use of multimodal data and deep learning techniques can help in the diagnosis and prediction of HCC. However, there is a limited number of works and available datasets for liver cancer, thus limiting the overall advancements of AI for liver cancer applications. Hence, more research should be undertaken to explore further the potential of multimodal deep learning in liver cancer applications.

Meta-Analysis
BACKGROUND
A number of therapeutic treatment strategies exist for patients with hepatocellular carcinoma (HCC) and portal vein thrombosis (PVT). The aim of this review is to provide a current understanding of treatment options and determine the relative effectiveness of treatment options in preventing mortality over 24 months.
METHODS
A search was conducted in PubMed, EMBASE and Cochrane CENTRAL from 2007 to 2022. Articles were screened to identify those that reported on all-cause mortality among treated, non-palliative patients with HCC and PVT. Study quality was assessed using the Cochrane Risk of Bias in Non-Randomized Studies of Interventions tool (ROBINS-1). Mortality rates at prespecified timepoints between 6 and 24 months were extracted and summarized using a random-effects DerSimonian-Laird model. This review was registered a priori on PROSPERO (CRD42022290708).
RESULTS
When comparing radiotherapy (RT) to sorafenib and combined transarterial chemoembolization (TACE), there was a trend that RT yields better survival at 6 months [odds ratio (OR) 0.70, 95% confidence interval (CI): 0.28-1.76]. When comparing sorafenib to Y90 and RT, sorafenib was associated with higher odds for mortality at 6 months (OR 2.20, 95% CI: 1.11-4.39). No significant differences were noticed from 12 to 24 months.
CONCLUSIONS
Future strategies for HCC with PVT should look at the combination of radiation and systemic treatments either concurrently or sequentially.

Meta-Analysis Review
Circulating tumour DNA (ctDNA) is a potential biomarker that could contribute to more judicious patient selection for personalised treatment. This review and meta-analysis gives an overview of the current knowledge in the literature investigating the value of ctDNA in patients with colorectal liver metastases (CRLM). A systematic search was conducted in electronic databases for studies published prior to the 26th of May 2023. Studies investigating the association between ctDNA and oncological outcomes in patients undergoing curative-intent local therapy for CRLM were included. Meta-analyses were performed to pool hazard ratios (HR) for the recurrence-free survival (RFS) and overall survival (OS). A total of eleven studies were included and nine were eligible for meta-analyses. Patients with detectable ctDNA after surgery experienced a significantly higher chance of recurrence (HR 3.12, 95% CI 2.27-4.28, < 0.000010) and shorter OS (HR 5.04, 95% CI 2.53-10.04, < 0.00001) compared to patients without detectable ctDNA. A similar association for recurrence was found in patients with detectable ctDNA after the completion of adjuvant therapy (HR 6.39, 95% CI 2.13-19.17, < 0.0009). The meta-analyses revealed no association between detectable ctDNA before surgery and the RFS and OS. These meta-analyses demonstrate the strong association between detectable ctDNA after treatment and oncological outcomes in CRLM patients.

Meta-Analysis
OBJECTIVE
Our study aimed to evaluate the efficacy and safety of Lenvatinib compared with Sorafenib for treating hepatocellular carcinoma (HCC) patients under real-world setting.
METHODS
We retrieved relevant literature through the PubMed, Embase, Web of Science, and Cochrane Library databases from 1 January 2000 to 25 June 2022. The differences in overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR) as well as treatment adverse related events were evaluated between HCC patients treated with Lenvatinib and Sorafenib using fixed or random-effects models. The MINORS evaluation questionnaire was used to assess the quality of the included literature.
RESULTS
This meta-analysis included a total of 9 single-arm studies and 6 comparative studies. In the meta-analysis, Lenvatinib showed significantly longer median OS than Sorafenib ( P < 0.01, MD = 1.20, 95% CI [0.92-1.48]), as well as median PFS ( P < 0.01, OR = 2.68, 95% CI [1.59-3.76]), and higher ORR( P < 0.01, OR = 5.36, 95% CI [3.42-8.40]), DCR( P < 0.01, OR = 2.17, 95% CI [1.64-2.86]). The occurrence of Hypertension was higher in Lenvatinib than in Sorafenib treatment ( P < 0.01, MD = 5.27, 95% CI [2.38-11.66]), and there was no significant difference in Hand-foot syndrome between Lenvatinib and Sorafenib.
CONCLUSION
We found that treatment with Lenvatinib in HCC patients resulted in better OS, PFS, and higher ORR and DCR compared to Sorafenib. However, safety data indicated that Lenvatinib did not exhibit a significant advantage.
