Disparities in race, ethnicity, sex, and age inclusion in pancreatic cancer screening studies: a systematic review and meta-analysis.

BACKGROUND AND AIMS: Substantial differences exist in pancreatic cancer outcomes across ethnoracial stratifications. We sought to assess racial, ethnic, sex, and age reporting and inclusion of participants in pancreatic cancer screening studies. METHODS: A systematic search of Cochrane Library, Ovid Embase, Google Scholar, Ovid MEDLINE, PubMed, Scopus, and Web of Science Core Collection from inception to 2022 was conducted. Original studies on pancreatic cancer screening were identified and assessed for reporting and inclusion on race, ethnicity, sex, and age. The pooled proportions of study participants for these characteristics were calculated and compared with population-based benchmarks. RESULTS: Among 27 eligible pancreatic cancer screening studies, 26 reported data on either sex, race, or ethnicity, with a total of 5273 participants. Information on participant sex was reported by 26, race by 12, and ethnicity by 8 studies. Participants in these studies were almost all white (pooled proportion, 93.1%; 95% confidence interval [CI], 89.7-96.4) and non-Latino (pooled proportion, 97.4%; 95% CI, 94.0-100), and these groups were over-represented when compared with the general population. Female participants were well represented, with a pooled proportion of 63.2% (95% CI, 59.9-66.6). When reported, mean or median participant age was <60 years. Meta-regression revealed higher proportions of female participants in studies from the United States (P = .002). No association between increasing participation of racial or ethnic under-represented populations and study quality, ascending year of publication, or source of study funding was noted. CONCLUSIONS: Substantial disparities in race, ethnicity, sex, and age reporting and inclusion in pancreatic cancer studies were noted, even among high-quality and publicly funded studies.

Submucosal tunneling endoscopic full-thickness resection for management of a rare case of esophageal GI stromal tumor.

Video 1The mass was identified at the upper- to mid-esophagus, 25 cm from the central incisors. No varices were seen on further examination of the esophagus. A 4-mm injector force needle was used to create a large submucosal injection using BlueBoost lifting agent proximal to the mass. A longitudinal mucosal incision was then made using the hybrid T-type electrocautery knife, 20 cm from the central incisors.The cutting current was the preset Endocut Q mode, and the coagulation setting was spray coag mode, effect 2 and 40 W.Next, tunnel creation by submucosal dissection was performed with a focus on keeping the submucosal space as clean as possible. Carbon dioxide was used for insufflation to prevent pneumoperitoneum.A smooth-surfaced oval mass was identified originating from the muscularis propria layer. Dissection was extended 2 cm distally beyond the mass. Next, resection of the mass was performed. First, the mucosal surface of the mass was dissected. Dissection began at the distal portion, proceeded to the left and right lateral borders, and then continued toward the proximal portion. The mass was dissected away from the muscularis propria.We focused on freeing the mass, ensuring this esophageal mass was intact throughout dissection. The attached bands of muscularis propria at the distal portion were carefully resected completely.Water irrigation was used at this time to ensure better visualization for resection. The remaining attached bands of muscularis propria were resected, ensuring complete en bloc resection. Afterward, the mass was suctioned into the cap and carefully retrieved as shown, and then sent to pathology for processing.The entire defect bed was inspected post-resection, and no perforation or bleeding was identified.The mucosal defect was completely closed with through-the-scope hemostatic clips in a longitudinal fashion beginning with approximation of the defect at the distal portion.

Pyloric Gastric Adenoma: Endoscopic Detection, Removal, and Echoendosonographic Characterization.

Pyloric gland adenomas (PGAs) are rare neoplasms found not only in the gastrointestinal tract but also in other extragastrointestinal organs. They have potential for malignant conversion, and early detection and removal is imperative to prevent invasive disease. PGAs prove difficult in management and surveillance given their rarity. However, increasing familiarity with histological appearance and use of advanced tools such as echoendosonography can bring greater understanding of their clinical history. We describe a unique case of a PGA detected within a hiatal hernia sac characterized with echoendosonography and highlight the need to develop surveillance protocols for these types of lesions.

Gastrointestinal Kaposi Sarcoma: A Rare Case of an Isolated Rectal Lesion in an Immunocompetent HIV-Negative Patient.

Kaposi sarcoma (KS) is a pathological endothelial growth associated with human herpes virus-8 which primarily affects the skin. In HIV-negative men who have sex with men, the clinical presentation of KS resembles the classic form limited to cutaneous or multifocal disease. In this report, we present a unique case of a healthy 61-year-old man who has sex with men with an isolated gastrointestinal KS who does not meet criteria for any of the typical KS clinical variants. Proper follow-up and regular HIV screenings are needed to evaluate the potential progression course of the disease in these patients.
