(Meta-Analysis)
Meta-Analysis
OBJECTIVE
To evaluate the treatment efficacy and the risk of adverse events of imiquimod for cervical intraepithelial neoplasia (CIN) and vaginal intraepithelial neoplasia (VAIN), compared with placebo or no intervention.
DATA SOURCES
We searched Cochrane, PubMed, ISRCTN registry, ClinicalTrials.gov , and the World Health Organization International Clinical Trials Registry Platform up to November 23, 2022.
METHODS OF STUDY SELECTION
We included randomized controlled trials and prospective nonrandomized studies with control arms that investigated the efficacy of imiquimod for histologically confirmed CIN or VAIN. The primary outcomes were histologic regression of the disease (primary efficacy outcome) and treatment discontinuation due to side effects (primary safety outcome). We estimated pooled odds ratios (ORs) of imiquimod, compared with placebo or no intervention. We also conducted a meta-analysis of the proportions of patients with adverse events in the imiquimod arms.
TABULATION, INTEGRATION, AND RESULTS
Four studies contributed to the pooled OR for the primary efficacy outcome. An additional four studies were available for meta-analyses of proportions in the imiquimod arm. Imiquimod was associated with increased probability of regression (pooled OR 4.05, 95% CI 2.08-7.89). Pooled OR for CIN in the three studies was 4.27 (95% CI 2.11-8.66); results of one study were available for VAIN (OR, 2.67, 95% CI 0.36-19.71). Pooled probability for primary safety outcome in the imiquimod arm was 0.07 (95% CI 0.03-0.14). The pooled probabilities (95% CI) of secondary outcomes were 0.51 (0.20-0.81) for fever, 0.53 (0.31-0.73) for arthralgia or myalgia, 0.31 (0.18-0.47) for abdominal pain, 0.28 (0.09-0.61) for abnormal vaginal discharge or genital bleeding, 0.48 (0.16-0.82) for vulvovaginal pain, and 0.02 (0.01-0.06) for vaginal ulceration.
CONCLUSION
Imiquimod was found to be effective for CIN, whereas data on VAIN were limited. Although local and systemic complications are common, treatment discontinuation is infrequent. Thus, imiquimod is potentially an alternative therapy to surgery for CIN.

Meta-Analysis
IMPORTANCE
Randomized clinical trials examining the effectiveness of neoadjuvant chemotherapy (NACT) for advanced ovarian cancer predominantly included patients with high-grade serous carcinomas. The use and outcomes of NACT in less common epithelial carcinomas are understudied.
OBJECTIVE
To investigate the uptake and survival outcomes in treatment with NACT for less common histologic subtypes of epithelial ovarian cancer.
DESIGN, SETTING, AND PARTICIPANTS
A retrospective cohort study and systematic literature review with meta-analysis was conducted using the National Cancer Database from 2006 to 2017 and the National Cancer Institute's Surveillance, Epidemiology, and End Results Program from 2006 to 2019. Data analysis was performed from July 2022 to April 2023. The evaluation included patients with stage III to IV ovarian cancer with clear cell, mucinous, or low-grade serous histologic subtypes who received multimodal treatment with surgery and chemotherapy.
EXPOSURES
Exposure assignment per the sequence of treatment: primary debulking surgery (PDS) followed by chemotherapy (PDS group) or NACT followed by interval surgery (NACT group).
MAIN OUTCOMES AND MEASURES
Temporal trends and characteristics of NACT use were assessed using multivariable analysis, and overall survival (OS) was assessed with the inverse probability of treatment weighting propensity score.
RESULTS
A total of 3880 patients were examined in the National Cancer Database including 1829 women (median age, 56 [IQR, 49-63] years) with clear cell, 1156 women (median age, 53 [IQR, 42-64] years) with low-grade serous, and 895 women (median age, 57 [IQR, 48-66] years) with mucinous carcinomas. NACT use increased in patients with clear cell (from 10.2% to 16.2%, 58.8% relative increase; P < .001 for trend) or low-grade serous (from 7.7% to 14.2%, 84.4% relative increase; P = .007 for trend) carcinoma during the study period. This association remained consistent in multivariable analysis. NACT use also increased, but nonsignificantly, in mucinous carcinomas (from 8.6% to 13.9%, 61.6% relative increase; P = .07 for trend). Across the 3 histologic subtypes, older age and stage IV disease were independently associated with NACT use. In a propensity score-weighted model, the NACT and PDS groups had comparable OS for clear cell (4-year rates, 31.4% vs 37.7%; hazard ratio [HR], 1.12; 95% CI, 0.95-1.33) and mucinous (27.0% vs 26.7%; HR, 0.90; 95% CI, 0.68-1.19) carcinomas. For patients with low-grade serous carcinoma, NACT was associated with decreased OS compared with PDS (4-year rates, 56.4% vs 81.0%; HR, 2.12; 95% CI, 1.55-2.90). Increasing NACT use and histologic subtype-specific survival association were also found in the Surveillance, Epidemiology, and End Results Program cohort (n = 1447). A meta-analysis of 4 studies, including the current study, observed similar OS associations for clear cell (HR, 1.13; 95% CI, 0.96-1.34; 2 studies), mucinous (HR, 0.93; 95% CI, 0.71-1.21; 2 studies), and low-grade serous (HR, 2.11; 95% CI, 1.63-2.74; 3 studies) carcinomas.
CONCLUSIONS AND RELEVANCE
Despite the lack of data on outcomes of NACT among patients with less common carcinomas, this study noted that NACT use for advanced disease has gradually increased in the US. Primary chemotherapy for advanced-stage, low-grade serous ovarian cancer may be associated with worse survival compared with PDS.

Meta-Analysis
OBJECTIVE
Postoperative bile leakage (POBL) is one of the most common complications after liver resection. However, current studies on the risk factors for POBL and their impacts on surgical outcomes need to be more consistent. This study aims to conduct a meta-analysis to analyze the risk factors for POBL after hepatectomy.
METHODS
We incorporated all eligible studies from Embase, PubMed, and the Web of Science database (until July 2022) into this study. RevMan and STATA software were used to analyze the extracted data.
RESULTS
A total of 39 studies, including 43,824 patients, were included in this meta-analysis. We found that gender, partial hepatectomy, repeat of hepatectomy, extended hepatectomy, abdominal drain, diabetes, Child≥B, solitary tumor, and chemotherapy are the factors of grade B and C POBL. Some recognized risk factors were considered potential risk factors for grade B and C bile leakage because no subgroup analysis was performed, like HCC, cholangiocarcinoma, major resection, posterior sectionectomy, bi-segmentectomy, S4 involved, S8 involved, central hepatectomy, and bile duct resection/reconstruction. Meanwhile, cirrhosis, benign diseases, left hepatectomy, and Segment 1 resection were not significant for grade B and C bile leakage. The influence of lateral sectionectomy, anterior sectionectomy, S1 involved, S3 involved, high-risk procedure, laparoscope, and blood loss>1000 mL on POBL of ISGLS needs further research. Meanwhile, POBL significantly influenced overall survival (OS) after liver resection.
CONCLUSIONS
We identified several risk factors for POBL after hepatectomy, which could prompt the clinician to decrease POBL rates and make more beneficial decisions for patients who underwent the hepatectomy.

Review
BACKGROUND
Total mesorectal excision is the standard of care for stage I rectal cancer. Despite major advances and increasing enthusiasm for modern endoscopic local excision (LE), uncertainty remains regarding its oncologic equivalence and safety relative to radical resection (RR).
OBJECTIVES
To assess the oncologic, operative, and functional outcomes of modern endoscopic LE compared to RR surgery in adults with stage I rectal cancer.
SEARCH METHODS
We searched CENTRAL, Ovid MEDLINE, Ovid Embase, Web of Science - Science Citation Index Expanded (1900 to present), four trial registers (ClinicalTrials.gov, ISRCTN registry, the WHO International Clinical Trials Registry Platform, and the National Cancer Institute Clinical Trials database), two thesis and proceedings databases, and relevant scientific societies' publications in February 2022. We performed handsearching and reference checking and contacted study authors of ongoing trials to identify additional studies.
SELECTION CRITERIA
We searched for randomized controlled trials (RCTs) in people with stage I rectal cancer comparing any modern LE techniques to any RR techniques with or without the use of neo/adjuvant chemoradiotherapy (CRT).
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methodological procedures. We calculated hazard ratios (HR) and standard errors for time-to-event data and risk ratios for dichotomous outcomes, using generic inverse variance and random-effects methods. We regrouped surgical complications from the included studies into major and minor according to the standard Clavien-Dindo classification. We assessed the certainty of evidence using the GRADE framework.
MAIN RESULTS
Four RCTs were included in data synthesis with a combined total of 266 participants with stage I rectal cancer (T1-2N0M0), if not stated otherwise. Surgery was performed in university hospital settings. The mean age of participants was above 60, and median follow-up ranged from 17.5 months to 9.6 years. Regarding the use of co-interventions, one study used neoadjuvant CRT in all participants (T2 cancers); one study used short-course radiotherapy in the LE group (T1-T2 cancers); one study used adjuvant CRT selectively in high-risk patients undergoing RR (T1-T2 cancers); and the fourth study did not use any CRT (T1 cancers). We assessed the overall risk of bias as high for oncologic and morbidity outcomes across studies. All studies had at least one key domain with a high risk of bias. None of the studies reported separate outcomes for T1 versus T2 or for high-risk features. Low-certainty evidence suggests that RR may result in an improvement in disease-free survival compared to LE (3 trials, 212 participants; HR 1.96, 95% confidence interval (CI) 0.91 to 4.24). This would translate into a three-year disease-recurrence risk of 27% (95% CI 14 to 50%) versus 15% after LE and RR, respectively. Regarding sphincter function, only one study provided objective results and reported short-term deterioration in stool frequency, flatulence, incontinence, abdominal pain, and embarrassment about bowel function in the RR group. At three years, the LE group had superiority in overall stool frequency, embarrassment about bowel function, and diarrhea. Local excision may have little to no effect on cancer-related survival compared to RR (3 trials, 207 participants; HR 1.42, 95% CI 0.60 to 3.33; very low-certainty evidence). We did not pool studies for local recurrence, but the included studies individually reported comparable local recurrence rates for LE and RR (low-certainty evidence). It is unclear if the risk of major postoperative complications may be lower with LE compared with RR (risk ratio 0.53, 95% CI 0.22 to 1.28; low-certainty evidence; corresponding to 5.8% (95% CI 2.4% to 14.1%) risk for LE versus 11% for RR). Moderate-certainty evidence shows that the risk of minor postoperative complications is probably lower after LE (risk ratio 0.48, 95% CI 0.27 to 0.85); corresponding to an absolute risk of 14% (95% CI 8% to 26%) for LE compared to 30.1% for RR. One study reported an 11% rate of temporary stoma after LE versus 82% in the RR group. Another study reported a 46% rate of temporary or permanent stomas after RR and none after LE. The evidence is uncertain about the effect of LE compared with RR on quality of life. Only one study reported standard quality of life function, in favor of LE, with a 90% or greater probability of superiority in overall quality of life, role, social, and emotional functions, body image, and health anxiety. Other studies reported a significantly shorter postoperative period to oral intake, bowel movement, and off-bed activities in the LE group.
AUTHORS' CONCLUSIONS
Based on low-certainty evidence, LE may decrease disease-free survival in early rectal cancer. Very low-certainty evidence suggests that LE may have little to no effect on cancer-related survival compared to RR for the treatment of stage I rectal cancer. Based on low-certainty evidence, it is unclear if LE may have a lower major complication rate, but probably causes a large reduction in minor complication rate. Limited data based on one study suggest better sphincter function, quality of life, or genitourinary function after LE. Limitations exist with respect to the applicability of these findings. We identified only four eligible studies with a low number of total participants, subjecting the results to imprecision. Risk of bias had a serious impact on the quality of evidence. More RCTs are needed to answer our review question with greater certainty and to compare local and distant metastasis rates. Data on important patient outcomes such as sphincter function and quality of life are very limited. Results of currently ongoing trials will likely impact the results of this review. Future trials should accurately report and compare outcomes according to the stage and high-risk features of rectal tumors, and evaluate quality of life, sphincter, and genitourinary outcomes. The role of neoadjuvant or adjuvant therapy as an emerging co-intervention for improving oncologic outcomes after LE needs to be further defined.

Meta-Analysis
BACKGROUND
The best approach for treating benign or low-grade malignant lesions localized in the pancreatic neck or body remains debatable. Conventional pancreatoduodenectomy and distal pancreatectomy (DP) are associated with a risk of impairment of pancreatic function at long-term follow-up. With advances in technology and surgical skills, the use of central pancreatectomy (CP) has gradually increased.
OBJECTIVES
The objective was to compare the safety, feasibility, and short-term and long-term clinical benefits of CP and DP in matched cases.
METHODS
The PubMed, MEDLINE, Web of Science, Cochrane, and EMBASE databases were systematically searched to identify studies published from database inception to February 2022 that compared CP and DP. This meta-analysis was performed using R software.
RESULTS
Twenty-six studies matched the selection criteria, including 774 CP and 1713 DP cases. CP was significantly associated with longer operative time ( P <0.0001), less blood loss ( P <0.01), overall and clinically relevant pancreatic fistula ( P <0.0001), postoperative hemorrhage ( P <0.0001), reoperation ( P =0.0196), delayed gastric emptying ( P =0.0096), increased hospital stay ( P =0.0002), intra-abdominal abscess or effusion ( P =0.0161), higher morbidity ( P <0.0001) and severe morbidity ( P <0.0001) but with a significantly lower incidence of overall endocrine and exocrine insufficiency ( P <0.01), and new-onset and worsening diabetes mellitus ( P <0.0001) than DP.
CONCLUSIONS
CP should be considered as an alternative to DP in selected cases such as without pancreatic disease, length of the residual distal pancreas is more than 5 cm, branch-duct intraductal papillary mucinous neoplasms, and a low risk of postoperative pancreatic fistula after adequate evaluation.

Meta-Analysis
BACKGROUND
The role of prophylactic drainage (PD) in gastrectomy for gastric cancer (GC) is not well-established. The purpose of this study is to compare the perioperative outcomes between the PD and non-drainage (ND) in GC patients undergoing gastrectomy.
METHODS
A systematic review of electronic databases including PubMed, Embase, Web of Science, the Cochrane Library, and China National Knowledge Infrastructure was performed up to December 2022. All eligible randomized controlled trials (RCTs) and observational studies were included and meta-analyzed separately. The registration number of this protocol is PROSPERO CRD42022371102.
RESULTS
Overall, 7 RCTs (783 patients) and 14 observational studies (4359 patients) were ultimately included. Data from RCTs indicated that patients in the ND group had a lower total complications rate (OR = 0.68; 95%CI:0.47-0.98; P = 0.04; I = 0%), earlier time to soft diet (MD = - 0.27; 95%CI: - 0.55 to 0.00; P = 0.05; I = 0%) and shorter length of hospital stay (MD = - 0.98; 95%CI: - 1.71 to - 0.26; P = 0.007; I = 40%). While other outcomes including anastomotic leakage, duodenal stump leakage, pancreatic leakage, intra-abdominal abscess, surgical-site infection, pulmonary infection, need for additional drainage, reoperation rate, readmission rate, and mortality were not significantly different between the two groups. Meta-analyses on observational studies showed good agreement with the pooled results from RCTs, with higher statistical power.
CONCLUSION
The present meta-analysis suggests that routine use of PD may not be necessary and even harmful in GC patients following gastrectomy. However, well-designed RCTs with risk-stratified randomization are still needed to validate the results of our study.

Meta-Analysis
BACKGROUND
Around 5-20% of patients who undergo surgery for advanced gastric cancer (AGC), which invades into the muscularis propria or beyond, have peritoneal carcinomatosis. The peritoneal recurrence rate is 10-54%, which is associated with a poor prognosis. The role of hyperthermic intraperitoneal chemotherapy (HIPEC) in AGC with and without peritoneal carcinomatosis is not clearly defined.
METHODS
The authors conducted a meta-analysis, in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, of the clinical trials and high-quality nonrandomized studies evaluating the role of HIPEC in AGC over the last 10 years. The studies were searched in PubMed, EMBASE, MEDLINE, and Cochrane databases between January 2011 to December 2021. Clinical data including overall survival, recurrence free survival, overall recurrence rate, peritoneal recurrence rate, and complications analyzed using RevMan 5.4.
RESULTS
Six randomized controlled trials and 10 nonrandomized studies, comprising a total of 1700 patients were included. HIPEC was associated with significantly improved OS at 3 [odd ratio (OR) 1.89, 95% CI: 1.17-3.05] and 5 years (OR 1.87, 95% CI: 1.29-2.71). HIPEC was associated with reduced overall recurrence (OR 0.49, 95% CI: 0.31-0.80) and peritoneal recurrence (OR 0.22, 95% CI: 0.11-0.47). HIPEC was not associated with increased complications. The occurrence of postoperative renal dysfunction was significantly higher in the HIPEC group (OR 3.94, 95% CI: 1.85-8.38).
CONCLUSION
The role of HIPEC in AGC has evolved over the past decade. HIPEC may improve survival rates and reduce recurrence rates in patients with AGC, without significant increase in complications and with a favorable impact on 3 and 5-year survival.

Ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) is rare in children, and localizing the source of EAS is often challenging. Here, we report EAS in an adolescent boy who presented with Cushingoid features and had endogenous ACTH-dependent hypercortisolism on hormonal evaluation. Abdominal ultrasound and CT revealed a hepatic lesion with characteristics suggestive of hemangioma, whereas the lesion was tracer non-avid on Ga-DOTANOC positron emission tomography/CT. A regional sampling of ACTH was done to confirm the hepatic lesion as the source of EAS, and a definitive ACTH gradient was observed between the hepatic vein and the right internal jugular vein. Further, a preoperative biopsy of the lesion revealed a small round cell tumor with positive immunostaining for ACTH and synaptophysin, suggestive of a neuroendocrine tumor. The patient was managed with partial hepatectomy, resulting in hormonal and clinical remission of Cushing syndrome. In a systematic review of pediatric EAS due to primary hepatic tumors (n = 11), calcifying nested stromal epithelial cell tumors were the most common. EAS-associated hepatic tumors were larger (≥10 cm) except benign primary hepatic neuroendocrine tumors (PHNET). The latter were misdiagnosed as hemangioma in two cases by anatomical imaging but correctly diagnosed by somatostatin receptor scintigraphy. Hepatic tumors causing EAS in children required extensive resection, except benign PHNET. Nevertheless, all benign tumors with an uncomplicated perioperative course demonstrated disease-free survival over a median follow-up period of two years.

Association of Laparoscopic Surgery with Improved Perioperative and Survival Outcomes in Patients with Resectable Intrahepatic Cholangiocarcinoma: A Systematic Review and Meta-Analysis from Propensity-Score Matched Studies.
BACKGROUND
Recent studies have associated laparoscopic surgery with better overall survival (OS) in patients with hepatocellular carcinoma (HCC) and colorectal liver metastasis (CRLM). The potential benefits of laparoscopic liver resection (LLR) over open liver resection (OLR) have not been demonstrated in patients with intrahepatic cholangiocarcinoma (iCC).
METHODS
A systematic review of the PubMed, EMBASE, and Web of Science databases was performed to search studies comparing OS and perioperative outcome for patients with resectable iCC. Propensity-score matched (PSM) studies published from database inception to May 1, 2022 were eligible. A frequentist, patient-level, one-stage meta-analysis was performed to analyze the differences in OS between LLR and OLR. Second, intraoperative, postoperative, and oncological outcomes were compared between the two approaches by using a random-effects DerSimonian-Laird model.
RESULTS
Six PSM studies involving data from 1.042 patients (530 OLR vs. 512 LLR) were included. LLR in patients with resectable iCC was found to significantly decrease the hazard of death (stratified hazard ratio [HR]: 0.795 [95% confidence interval [CI]: 0.638-0.992]) compared with OLR. Moreover, LLR appears to be significantly associated with a decrease in intraoperative bleeding (- 161.47 ml [95% CI - 237.26 to - 85.69 ml]) and transfusion (OR = 0.41 [95% CI 0.26-0.69]), as well as with a shorter hospital stay (- 3.16 days [95% CI - 4.98 to - 1.34]) and a lower rate of major (Clavien-Dindo ≥III) complications (OR = 0.60 [95% CI 0.39-0.93]).
CONCLUSIONS
This large meta-analysis of PSM studies shows that LLR in patients with resectable iCC is associated with improved perioperative outcomes and, being conservative, yields similar OS outcomes compared with OLR.

Meta-Analysis
Background: immunonutrition has been introduced and proposed to have positive modulating effects on inflammatory and immune responses in surgical patients. This meta-analysis aimed to assess whether perioperative enteral immunonutrition (EIN) can reduce postoperative complications or reduce inflammatory responses in esophageal cancer (EC) patients undergoing esophagectomy. Methods: PubMed, Embase, Web of science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of EIN before and/or after surgery in EC patients undergoing esophagectomy were identified. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. Results: ten RCTs involving 1,052 patients were included in the meta-analysis, including 573 patients in the EIN group and 479 patients in the enteral nutrition (EN) group. Overall, no significant difference was observed between the two groups in the incidence of postoperative pneumonia, surgical site infection, intra-abdominal abscess, septicemia, and urinary tract infection. No significant incidence of postoperative anastomotic leakage, acute respiratory distress syndrome (ARDS), and in-hospital mortality was found. Conclusions: perioperative enteral immunonutrition did not reduce the incidence of infectious complications and anastomotic leakage in EC patients undergoing esophagectomy, nor did it reduce postoperative CRP and IL-6, but did not increase in-hospital mortality.
