EUS-FNA is clinically very useful for establishing the diagnosis of abdominal lymphadenopathy of unknown cause and can provide sufficient tissue for IHC and subtyping of lymphomas.
E-PASS scoring system is useful to evaluate for morbidity after PD. Neoadjuvant chemotherapy and IORT could be adapted without significant extra risk for surgical complication.
There were lymph vessels in the submucosal layer of the common bile duct, and cancer cells can spread through these channels in addition to the large lymph vessels in subserosal layer around the extrahepatic bile duct in GC. The present results would support the concept of en bloc resection of the extrahepatic bile duct in curative resection for T2 GC.
Our results show a high frequency of adenomas in the ileal pouch mucosa, with evolution into carcinoma in some patients. Regular endoscopic surveillance of the pouch is recommended at a frequency similar to that for the rectal mucosa after IRA in pouch patients with FAP.
The characteristic histological feature of pancreatic mucinous cystic neoplasm (MCN) is ovarian-like stroma (OS) underlying the epithelium and existence of estrogen receptors and progesterone receptors in the nucleus of OS. We experienced a case of pancreatic MCN which was activated during pregnancy and confirmed the existence of estrogen receptors and progesterone receptors. In cases with potential factors for malignancy, surgical resection of MCN may be needed during pregnancy. On the other hand, in cases without these, as female sex hormones may have an influence on the behavior of pancreatic MCN during pregnancy, the timing of surgery should be decided on a case-by-case basis, taking into consideration the status of the malignancy, the stage of the pregnancy, and the condition of the mother and fetus.
MiR-101 targets EZH2 at the posttranscriptional level, and loss of miR-101 could be a trigger for the adenomacarcinoma sequence of IPMN by upregulation of EZH2. This study suggests miR-101-EZH2 blockade as a potential therapeutic target in IPMN carcinogenesis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
