Endoscopic Biliary Darinage (EBD) versus Percutaneous Transhepatic Biliary Drainage (PTBD) for biliary drainage in patients with Perihilar Cholangiocarcinoma (PCCA): A systematic review and meta-analysis.
Biliary drainage for Perihilar Cholangiocarcinoma (PCCA) can be performed either by endoscopic retrograde cholangiopancreatography or Percutaneous Transhepatic Biliary Drainage (PTBD). To date there is no consensus about which method is preferred. Taking that into account, the aim of this study is to compare Endoscopic Biliary Drainage (EBD) versus percutaneous transhepatic biliary drainage in patients with perihilar cholangiocarcinoma through a systematic review and metanalysis. A comprehensive search of multiple electronic databases was performed. Evaluated outcomes included technical success, clinical success, post drainage complications (cholangitis, pancreatitis, bleeding, and major complications), crossover, hospital length stay, and seeding metastases. Data extracted from the studies were used to calculate Mean Differences (MD). Seventeen studies were included, with a total of 2284 patients (EBD = 1239, PTBD = 1045). Considering resectable PCCA, the PTBD group demonstrated lower rates of crossover (RD = 0.29; 95% CI 0.07‒0.51; p = 0.009 I² = 90%), post-drainage complications (RD = 0.20; 95% CI 0.06‒0.33; p < 0.0001; I² = 78%), and post-drainage pancreatitis (RD = 0.10; 95% CI 0.05‒0.16; p < 0.0001; I² = 64%). The EBD group presented reduced length of hospital stay (RD = -2.89; 95% CI -3.35 ‒ -2,43; p < 0.00001; I² = 42%). Considering palliative PCCA, the PTBD group demonstrated a higher clinical success (RD = -0.19; 95% CI -0.27 ‒ -0.11; p < 0.00001; I² = 0%) and less post-drainage cholangitis (RD = 0.08; 95% CI 0.01‒0.15; p = 0.02; I² = 48%) when compared to the EBD group. There was no statistical difference between the groups regarding: technical success, post-drainage bleeding, major post-drainage complications, and seeding metastases.

Meta-Analysis Review
Background: Celiac disease (CD) is an autoimmune enteropathy affecting approximately 1% of the population and is associated with an increased risk of enteropathy-associated T-cell lymphoma and small bowel adenocarcinoma, whereas the association between CD and other malignancies is unclear. Since pancreatic cancer (PC) remains one of the most lethal neoplasms and its incidence is increasing despite numerous ongoing research on diagnostic biomarkers and novel therapies, we aimed to investigate whether CD has an impact on the risk of PC. Material and Methods: We performed a systematic review of the literature published from January 2000 to March 2022 in two databases: Web of Science and Scopus and a meta-analysis of eligible studies. Results: Our search identified eight publications included in the systematic review. A total of five studies involving 47,941 patients, including 6399 CD patients with malignancies and 1231 PC cases were included in the meta-analysis and 221 cases of PC in CD patients with other cancers were recognized. The pooled OR for PC was 1.46 (95% CI 1.26−1.7) with significant heterogeneity (89.1%; p < 0.05), suggesting that CD patients with malignancies were at higher risk for PC. Conclusions: The association between CD and PC is uncertain. However, the results of the current meta-analysis may indicate an increased risk of PC in the group of patients with CD and other cancers. Further multicenter studies are warranted.

Review
INTRODUCTION
The aim of this review was to characterize the second- and later-line (≥2L) treatment landscape for patients with metastatic pancreatic ductal adenocarcinoma (mPDAC).
METHODS
This systematic literature review (PROSPERO: CRD42021279753) involved searches of MEDLINE® and Embase to identify results from prospective studies of ≥2L treatment options for metastatic pancreatic cancer published from 2016 to 2021. Publications were screened according to predetermined eligibility criteria; population-level data were extracted using standardized data fields. Publication quality was assessed according to Grading of Recommendations Assessment, Development and Evaluation (GRADE). The data were analyzed descriptively, grouped by drug class.
RESULTS
Sixty publications were identified, including 23 relating to comparative trials. GRADE assessment found that, of these 23 trials, 83% reported high or moderate-quality evidence. Of the publications relating to comparative trials, nine (three trials) reported favorable results: the pivotal phase 3 NAPOLI-1 trial for liposomal irinotecan; a phase 3 trial of non-liposomal irinotecan within the FOLFIRINOX regimen; and a phase 2 trial of eryaspase plus chemotherapy.
CONCLUSIONS
The level of unmet need for ≥2L treatment options for mPDAC remains high. Irinotecan-based regimens currently offer the greatest promise. Investigations into paradigm-changing agents and combination approaches continue.

Meta-Analysis
INTRODUCTION
Due to the specific location, the potential advantages of laparoscopic gastrectomy (LG) compared with open gastrectomy (OG) for Siewert II/III adenocarcinoma of the esophagogastric junction (AEG) remain uncertain. The current study aimed to compare the short- and long-term outcomes of LG versus OG in treating Siewert type II/III adenocarcinoma.
METHODS
We searched PubMed, Embase, Web of Science, MEDLINE (hosted by Ovid), and the Cochrane Library for publications till July 2022 and then used the RevMan 5.3 software for statistical analysis.
RESULTS
Ten publications from 10 medical centers were included, with 1,516 cases from the LG group and 1,219 from the OG group. Meta-analysis results showed that the LG group was superior to the OG group in intraoperative blood loss, hospital stay, lymph nodes retrieved, time to ambulation, time to first flatus, time to diet, 5-year overall survival, and 5-year disease-free survival. There was no significant difference between the two groups in operative time, overall complications, proximal margin, distal margin, pulmonary infection, anastomotic leakage, mortality, ileus, or absolute infection.
CONCLUSIONS
Compared with OG, LG is associated with better surgical and long-term outcomes in Siewert type II/III AEG. LG is a safe and feasible option for treating Siewert type II/III AEG. However, studies with large sample sizes, long follow-up periods, and rigorous designs are needed for verification.

OBJECTIVE
To evaluate the consistencies and inconsistencies between distal cholangiocarcinoma (DCCA) and pancreatic ductal adenocarcinoma (PDCA) regarding their biological features and long-term prognosis.
METHODS
PubMed, the Cochrane Library, and EMBASE were searched to find comparative studies between DCCA and PDCA. RevMan5.3 and Stata 13.0 software were used for the statistical analyses.
RESULTS
Eleven studies with 4,698 patients with DCCA and 100,629 patients with PDCA were identified. Pooled results indicated that patients with DCCA had a significantly higher rate of preoperative jaundice (p = 0.0003). Lymphatic metastasis (p < 0.00001), vascular invasion (p < 0.0001), and peri-neural invasion (p = 0.005) were more frequently detected in patients with PDCA. After curative pancreaticoduodenectomy (PD), a significantly higher R0 rate (p < 0.0001) and significantly smaller tumor size (p < 0.00001) were detected in patients with DCCA. Patients with DCCA had a more favorable overall survival (OS) (p < 0.00001) and disease-free survival (DFS) (p = 0.005) than patients with PDCA. However, postoperative morbidities (p = 0.02), especially postoperative pancreatic fistula (POPF) (p < 0.00001), more frequently occurred in DCCA.
CONCLUSION
Patients with DCCA had more favorable tumor pathological features and long-term prognosis than patients with PDCA. An early diagnosis more frequently occurred in patients with DCCA. However, postoperative complications, especially POPF, were more frequently observed in patients with DCCA.

Needle-tract seeding (NTS) has been sporadically reported as complication of Endoscopic Ultrasound (EUS)-guided aspiration (FNA) in pancreatic adenocarcinoma (PDAC). However, the evidence of its treatment and outcome is sparse. Adhering to PRISMA guidelines, we conducted a systematic review of EUS-FNA NTS cases of PDAC and analyzed their management and outcome. Up to September 2022, the search query retrieved forty-five cases plus an unpublished case from our center, for a total of forty-six; 43.6% were male, with a mean age of 68.6 years. Thirty-four patients (87.1%) underwent an initial surgical resection, with only 44.1% and 5.9% undergoing adjuvant and neoadjuvant chemotherapy, respectively, and 5.9% undergoing both. The NTS nodule was mostly located in the posterior gastric wall, developing at a median of 19 months after primary resection; 82.4% underwent surgical resection of the seeding, while for 17.6%, palliative chemotherapy treatment. Follow-up after NTS diagnosis and treatment was reported for only twenty-three patients: when NTS was treated with surgery, the median overall survival was 26.5 months compared to 15.5 if treated with radio/chemotherapy. NTS after EUS-FNA of PDAC occurs late and might be treated aggressively with good results. Interestingly, only a low number of patients developing NTS underwent chemotherapy for the primary cancer, suggesting its possible protective role.

BACKGROUND AND AIMS
Somatostatinoma of the ampulla of Vater (SAV) is a rare neuroendocrine tumor that usually appears with atypical clinical manifestations and is associated with Von Recklinghausen's disease. The aims of this study were to systematically review the literature regarding SAV and to highlight the clinicopathological characteristics and optimal therapeutic management of this rare entity.
METHODS
A systematic search of the literature in PubMed/Medline and Scopus databases was performed by two independent investigators, including all case reports and case series concerning SAVs from 1980 until September 2021.
RESULTS
In total, 37 articles were retrieved, including 43 patients, with a male to female ratio of 1.8:1 and a mean age of 46.8 ± 11.3 years (mean, SD). For 23 out of 43 patients (53.5%), Von Recklinghausen's disease was proved. The main clinical manifestations were abdominal pain (41.9%), jaundice (27.9%), weight loss (20.9%) and bowel disorders (20.9%). Typical histological findings included psammoma bodies, nests or clusters of epithelial cells with eosinophilic cytoplasm, while somatostatin staining was positive in 35 patients (81.4%), chromogranin-A in 21 patients (48.8%) and synaptophysin in 18 patients (41.9%). Surgery was the initial therapeutic approach in 34 patients (79.1%), whereas Whipple's procedure was the preferred surgical approach in 23 patients (53.4%). The longest survival among included patients was 13 years and only two postoperative deaths (4.7%) were reported.
CONCLUSIONS
Somatostatinomas of the ampulla of Vater are rare malignancies that require increased physicians' suspicion and accurate surgical approach in order to achieve optimal therapeutic results.

Although uncommon, extrahepatic cholangiocarcinoma (EHCC) is a deadly malignancy, and the treatment approaches remain controversial. While surgery remains the only cure, few patients are candidates for resection up front, and there are high rates of both local and distant failure following resection. Herein, we systematically review the available evidence regarding treatment approaches for patients with EHCC, including surgery, radiation, and chemotherapy. The evidence regarding treatment outcomes was assessed using the Population, Intervention, Comparator, Outcome, and Study design (PICOS) framework. A summary of recommendations based on the available literature is outlined for specific clinical scenarios encountered by providers in the clinic to guide the management of these patients.

Prostate cancer is a common malignancy affecting men worldwide. While the vast majority of newly diagnosed prostate cancers are categorized as adenocarcinomas, a spectrum of uncommon tumor types occur including those with small cell and neuroendocrine cell features. Benign neuroendocrine cells exist in the normal prostate microenvironment, and these cells may give rise to primary neuroendocrine carcinomas. However, the more common development of neuroendocrine prostate cancer is observed after therapeutics designed to repress the signaling program regulated by the androgen receptor which is active in the majority of localized and metastatic adenocarcinomas. Neuroendocrine tumors are identified through immunohistochemical staining for common markers including chromogranin A/B, synaptophysin and neuron specific enolase (NSE). These markers are also common to neuroendocrine tumors that arise in other tissues and organs such as the gastrointestinal tract, pancreas, lung and skin. Notably, neuroendocrine prostate cancer shares biochemical features with nerve cells, particularly functions involving the secretion of a variety of peptides and proteins. These secreted factors have the potential to exert local paracrine effects, and distant endocrine effects that may modulate tumor progression, invasion, and resistance to therapy. This review discusses the spectrum of factors derived from neuroendocrine prostate cancers and their potential to influence the pathophysiology of localized and metastatic prostate cancer.

Meta-Analysis Review
BACKGROUND
Patients with ductal adenocarcinoma of the body and tail of the pancreas usually remain asymptomatic until late in the course of the disease, and the survival of such patients depends on multiple factors, which may affect the therapeutic approach and patient survival. Hence, the aim of this study was to investigate such risk factors by pooling various available studies.
METHODS
A systematic review was conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines between January 1, 2007, and December 31, 2016, using the following databases: Medline, Scopus, the Cochrane Library, and Google Scholar. Studies were selected according to the predesigned eligibility criteria, and information was extracted for demographics, clinical features, and survival outcomes. Data were pooled using fixed- or random-effects models.
RESULTS
Sixteen studies were included (5,660 patients) with a median age of 64.8 years and a median survival of 28.5 (range 13-38) months. Identified significant factors for overall survival were higher age (hazard ratio [HR] = 1.211), men (HR = 1.182), presence of lymph node metastasis (HR = 1.964), multivisceral resection (HR = 1.947), N stage (1 versus 0; HR = 1.601), surgical margin (R0 versus No R0; HR = 0.519) and tumor size (>3 cm; HR = 1.890).
CONCLUSION
The pooled results of this study revealed several risk factors for overall survival in patients with left-sided pancreatic cancer.
