Kaur J, Jaruvongvanich V, Chandrasekhara V. Endoscopic ultrasound-guided injectable therapy for pancreatic cancer: A systematic review. World J Gastroenterol 2022; 28:2383-2395. [PMID: 35800184 PMCID: PMC9185216 DOI: 10.3748/wjg.v28.i21.2383] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Revised: 01/18/2022] [Accepted: 04/25/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Given the low survival rate in pancreatic cancer, new therapeutic techniques have been explored, especially for unresectable or borderline resectable disease. Endoscopic ultrasound (EUS) provides real-time imaging and minimally invasive access for local and targeted injection of anti-tumor agents directly into the pancreatic tumor. Limited studies have been reported using this technique for the treatment of pancreatic ductal adenocarcinoma (PDAC).
AIM To evaluate the progress made with EUS-guided injectable therapies in the treatment of PDAC.
METHODS All original articles published in English until July 15, 2021, were retrieved via a library-assisted literature search from Ovid Evidence-Based Medicine Reviews and Scopus databases. Reference lists were reviewed to identify additional relevant articles. Prospective clinical studies evaluating the use of EUS-guided injectable therapies in PDAC were included. Studies primarily directed at non-EUS injectable therapies and other malignancies were excluded. Retrieved manuscripts were reviewed descriptively with on critical appraisal of published studies based on their methods and outcome measures such as safety, feasibility, and effectiveness in terms of tumor response and survival. Heterogeneity in data outcomes and therapeutic techniques limited the ability to perform comparative statistical analysis.
RESULTS A total of thirteen articles (503 patients) were found eligible for inclusion. The EUS-injectable therapies used were heterogeneous among the studies consisting of immunotherapy (n = 5) in 59 patients, chemotherapy (n = 1) in 36 patients, and viral and other biological therapies (n = 7) in 408 patients. Eleven of the studies reviewed were single armed while two were double armed with one randomized trial and one non-randomized comparative study. Overall, the included studies demonstrated EUS-guided injectable therapies to be safe and feasible with different agents as monotherapy or in conjunction with other modalities. Promising results were also observed regarding their efficacy and survival parameters in patients with PDAC.
CONCLUSION EUS-guided injectable therapies, including immunotherapy, chemotherapy, and viral or other biological therapies have shown minimal adverse events and potential efficacy in the treatment of PDAC. Comparative studies, including controlled trials, are required to confirm these results in order to offer novel EUS-based treatment options for patients with PDAC.

Abstract
For the first several years after its development, endoscopic ultrasound (EUS) was primarily limited to identification of pancreatic malignancies. Since this time, the field of EUS has advanced at a tremendous speed in terms of additional clinical diagnostic and therapeutic uses. The combination of ultrasound with endoscopy provides a unique interventional modality that is a minimally invasive alternative to various surgical interventions. Given the expanding recommended indications for EUS, this article will serve to review the most common uses with supporting evidence, while also exploring innovative endeavors that may soon become common clinical practice.

Abstract
OBJECTIVE The purpose of this study was to evaluate the prognostic relevance of SMAD4 expression in pancreatic cancer. METHODS We analyzed the correlations between SMAD4 expression and clinicopathological parameters and outcome in 174 patients with pancreatic cancer. Specimens were also classified into subtypes reflecting epithelial-to-mesenchymal transition, based on E-cadherin and vimentin. RESULTS We found that 59.8% (104/174) of patients were SMAD4 and 40.2% (70/174) were SMAD4. Disease-specific survival in patients with SMAD4 was significantly better than that in SMAD4. SMAD4 status was significantly correlated with portal vein invasion, lymph vessel invasion, and perineural invasion and was an independent prognostic factor. SMAD4 was significantly associated with mesenchymal phenotype. The loss of SMAD4 expression was found in 49.4% of patients with no vascular invasion, 61.9% with portal vein invasion, 76.5% with common hepatic artery invasion, and 80.8% with superior mesenteric artery invasion. In addition, the specimens from 59.0% of patients with local recurrence, 66.7% of those with both local and distant recurrence, and 73.7% of those with distant recurrence were SMAD4. CONCLUSIONS The loss of SMAD4 expression is an independent prognostic factor and seems to be associated with tumor progression, pattern of failure, and epithelial-to-mesenchymal transition status. Preoperative stratification based on SMAD4 could lead to appropriate treatment strategy.

Abstract
OBJECTIVE The goal of this retrospective study was to clarify the clinical implications of the status of the 3 major genes (CDKN2A/p16, TP53, and SMAD4/DPC4). BACKGROUND Recent whole-exome sequencing had shown that the landscape of the pancreatic ductal adenocarcinoma (PDAC) genome is notable for 4 frequently mutated genes (KRAS, TP53, CDKN2A/p16, and SMAD4/DPC4). METHODS We determined immunohistochemically the status of TP53, CDKN2A/p16, and SMAD4/DPC4 among the 4 genes because the KRAS gene is mutated in virtually all PDAC patients, and analyzed relationships with clinicopathological findings, including survival and patterns of disease progression, in 106 patients with PDAC undergoing radical surgery. RESULTS Abnormal immunolabeling of p53 was detected in 81.1% of PDACs and was significantly associated with tumor dedifferentiation (P = 0.022) and the presence of locoregional recurrence (P = 0.020). Loss of p16 and Smad4/Dpc4 immunolabeling was identified in 67.0% and 60.4%, respectively. Loss of p16 immunolabeling was associated with lymphatic invasion (P = 0.012) and postoperative widespread metastases (P < 0.001). A significant correlation was found between Smad4/Dpc4 immunolabeling and tumor size (P = 0.006), lymphatic invasion (P = 0.033), and lymph node metastasis (P = 0.006). Interestingly, all of the 6 patients demonstrating 5-year survival had intact SMAD4/DPC4. Kaplan-Meier survival analysis showed that lymph node metastasis (P = 0.001), lymphatic invasion (P = 0.008), the tumor (T) factor (T3 vs. T1/T2, P = 0.004), loss of p16 immunolabeling (P = 0.029), and loss of Smad4/Dpc4 immunolabeling (P < 0.001) were significantly associated with shorter overall survival. Multivariate analysis revealed that loss of Smad4/Dpc4 immunolabeling was an independent and significant poor prognostic factor for overall and disease-free survival. On analysis of combinations of the status of these 3 genes, increasing number of alterations reflected poorer survival. CONCLUSIONS Genetic alterations of these 3 genes and their accumulation are strongly associated with malignant behavior of PDAC. Their immunohistochemical assessment at the time of diagnosis may provide a new prognostic tool, assisting in deciding optimal therapeutic strategies for patients.

Abstract
Indeterminate bilary strictures present the clinician with a wide differential diagnosis. Histological confirmation is usually required for treatment, but tissue acquisition remains challenging. Novel developments in endoscopic technology, such as single operator cholangioscopy and confocal endomicroscopy, have led to improvements in diagnostic accuracy in recent years. In patients with non-resectable malignant biliary obstruction, effective biliary decompression improves symptoms and enables patients to undergo palliative therapies. Improvements in endoscopic techniques, biliary stents and the development of local ablative techniques have led to further improvements in stent patency and survival in these patients. In this article, we review emerging diagnostic and therapeutic techniques for the endoscopic management of indeterminate biliary strictures.

Abstract
BACKGROUND AND STUDY AIMS Diagnostic yield of endoscopic ultrasound (EUS)-fine-needle aspiration (FNA) varies depending on the equipment used and the site targeted. Multiple needle passes are usually required to obtain a diagnosis. A new needle incorporating a side-port carries a theoretical advantage regarding acquisition of cytological material. The aim of the study was to demonstrate the safety and efficacy of the Olympus side-port needle in solid upper gastrointestinal indications. PATIENTS AND METHODS A prospective multicenter evaluation of patients referred for EUS-FNA for solid lesions was performed across six tertiary gastroenterology referral centers in four capital cities in Australia. The main outcome measures include cytological diagnosis, number of needle passes required for diagnosis and complication rates. RESULTS Thirty patients (17 men; 13 women) with a mean age of 67.5 years were studied. Indications included pancreatic or biliary mass in 24 patients, retroperitoneal or periduodenal mass in 2, enlarged lymph node in 2, a gastric submucosal tumor in 1 and a subcarinal mass in 1. The mean size of the lesions was 3.47 cm (range, 0.5-8 cm). All but one case had a diagnosis made (96.7%). The mean number of passes required to reach a diagnosis was 1.7. In neoplastic lesions the diagnosis was made with a mean of 1.6 passes. No complications were encountered. CONCLUSIONS The new EUS-FNA needle with side port appears effective and safe in solid upper gastrointestinal EUS-FNA indications.

Abstract
INTRODUCTION Pancreatic acinar cell carcinoma (ACC) has several unique characteristics, such as its progression pattern, spreading into the pancreatic duct and large blood vessels, and its secretion of pancreatic exocrine enzymes, which induces a paraneoplastic syndrome. CASE REPORT A 79-year-old Japanese man, with medical history of chronic renal failure, was referred to our institution for the examination of his abdominal pain and hyperglycemia. Plain computed tomography demonstrated a mass lesion, 4 cm in diameter, in the body of pancreas. Abdominal ultrasonogram demonstrated a bulky, hypoechoic mass extending into the splenic vein. Multiple hepatic nodules were detected on suspicion of metastasis. Positron emission tomography using 18F-fluorodeoxyglucoase revealed the tumor extended towards the pancreatic head through the main pancreatic duct. We obtained the tumor tissues from the pancreatic body using endoscopic ultrasound-guided fine-needle aspiration biopsy. Pathological diagnosis, supported by immunohistochemistry, was that of an ACC. In the follow-up period, he complained of subcutaneous nodules and arthralgia on his lower legs. Serum and intra-articular lipase levels were elevated, 6,420 I/U and 594 I/U, respectively. Histology of the skin lesion at the knee joint showed necrotizing panniculitis with eosinophilic infiltration. The patient was treated with weekly gemcitabine, but succumbed to acute respiratory distress unexpectedly 2 months after the initial diagnosis.

Abstract
Biliary tract cancers (gallbladder cancer, intra- and extra-hepatic cholangiocarcinoma and selected periampullary cancers) accounted for 12,760 new cases of cancer in the USA in 2010. These tumors have a dismal prognosis with most patients presenting with advanced disease. Early, accurate diagnosis is essential, both for potential cure where possible and for optimal palliative therapy in all others. This review examines the currently available and emerging technologies for diagnosis and treatment of this group of diseases.

Abstract
BACKGROUND Diagnostic yield of endoscopic ultrasound-guided fine-needle aspiration (EUS FNA) varies relating to the equipment used and the site targeted. Multiple needle passes are usually required to obtain a diagnosis. A new needle incorporating a side port carries a theoretical advantage regarding acquisition of cytological material. METHODS To demonstrate the safety and efficacy of the Olympus side-port needle across a spectrum of indications for EUS FNA, a prospective collection of 16 consecutive cases was undertaken at a tertiary gastroenterology referral centre in metropolitan Sydney, Australia. EUS FNA was performed with the novel Olympus side-port needle. EUS FNA was otherwise performed in the conventional fashion. The number of needle passes required for diagnosis, number of passes total, diagnosis on cytology and conclusive diagnosis were recorded. RESULTS Diagnostic material was obtained at the first pass in 56.2% of patients. Mean number of passes required to reach a diagnosis was 2.1. Diagnosis was made on first pass in 62.5% of solid non-lymph-node lesions. The diagnosis was reached in 94%. CONCLUSIONS The novel side-port needle is safe and effective; further evaluation with a prospective randomized trial is warranted.

Abstract
The use of stents throughout the gastrointestinal tract has evolved over the past century. The evolution of endoscopic ultrasound and significant improvements in stent design are key factors that have allowed endoscopists to drive the use of stents in gastroenterology into new directions. Endoscopic creativity remains crucial in the evolution of any new endoscopic technology. Finally, the use of multidisciplinary teams, including endoscopists, radiologists, and surgeons, allows for the exchange of ideas and procedural planning necessary for successful innovation.

Abstract
A 77-year-old man was referred to our hospital for further investigation of pancreatic masses. Imaging studies revealed hypovascular masses in the pancreatic head and body. Total pancreatectomy was performed under the diagnosis of double primary pancreatic carcinomas. Macroscopic examination revealed 3 nodules: one each in the pancreatic head, body, and tail. Microscopically, all 3 lesions showed similar carcinoma cells, which communicated with each other via the intraductal component, indicating a single large tumor. Incidentally, we also identified an adenocarcinoma of the common bile duct (CBD). The final diagnosis was synchronous double cancer involving the whole pancreas and the CBD.
