The distinction between PDAC and chronic pancreatitis is sometimes challenging on routine histopathological examination, highlighting the need to identify biomarkers that can facilitate this distinction. This retrospective study was conducted to evaluate the diagnostic utility of nuclear receptor co-activator 3 (NCOA3), Maspin and Von Hippel-Lindau protein (VHL) immunostaining in PDAC. Eighty cases of PDAC, 46 cases of chronic pancreatitis and 53 normal pancreatic tissue were immunohistochemically assessed using NCOA3, Maspin and VHL antibodies on sections from a tissue microarray. NCOA3, Maspin and VHL were positive in 90 %, 100 % and 35 %, of PDAC cases respectively, whereas NCOA3, Maspin and VHL expressions were positive in 3.8 %, 0 and 100 % of normal pancreatic tissue and in 15.2 %, 21.7 % and 97.8 % of chronic pancreatitis cases respectively. Significant differences were observed between PDAC and other groups regarding NCOA3, Maspin and VHL expression (<em>p</em> &lt; 0.001). The H scores of NCOA3, Maspin and VHL could significantly distinguish between PDAC and normal cases with high sensitivity (90 %, 100 % and 98.75 % respectively) and specificity (100 %, 100 % and 96.23 % respectively). Similar findings were found in the distinction between PDAC and chronic pancreatitis (Sensitivity: 90 %, 95.25 % and 98.75 %; specificity: 100 %, 100 % and 93.48 % for NCOA3, Maspin and VHL respectively). In conclusion, NCOA3 and Maspin were found to be significantly expressed in PDAC compared to non-tumorous tissue while VHL was significantly expressed in non-tumorous tissue. A panel of NCOA3, Maspin and VHL could potentially distinguish PDAC from non-tumorous pancreatic tissue.</p></div>","PeriodicalId":50768,"journal":{"name":"Annals of Diagnostic Pathology","volume":"73 ","pages":"Article 152356"},"PeriodicalIF":2.0,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141428791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MALAT1 is a lncRNA that is expressed in endocrine and many other neoplasms and it has been shown to have oncogenic and/or tumor suppressor effects in tumor development. Olfactory neuroblastomas arise in the nasal cavity while sympathetic neuroblastomas are present mainly in the adrenal and periadrenal regions. These neoplasms have overlapping histopathological features. Rare cases of sympathetic neuroblastomas metastatic to the nasal cavity have been reported. PHOX2B has been shown to be relatively specific for sympathetic neuroblastomas, but only a limited number of cases of olfactory neuroblastomas have been examined for PHOX2B expression. This study aimed to explore the potential utilization of MALAT1 and PHOX2B in distinguishing these two entities. Tissue microarrays (TMA) were created for olfactory neuroblastomas (<em>n</em> = 26) and sympathetic neuroblastomas (<em>n</em> = 52). MALAT1 lncRNA expression was assessed by in situ hybridization using RNAScope technology. TMA slides were scanned by Vectra multispectral imaging system and image analysis and quantification were performed with inForm software. PHOX2B expression was analyzed by immunohistochemistry. MALAT1 showed predominantly nuclear expression in both tumor types and MALAT1 expression was 2-fold higher in olfactory neuroblastomas compared to sympathetic neuroblastomas (<em>p</em> &lt; 0.0001). PHOX2B showed nuclear staining in most sympathetic neuroblastomas (51/52, 98 %) while only 1 olfactory neuroblastoma (3.8 %) was focally positive for this marker.

Two tumors were intrapulmonary neoplasms, while three were pleural-based. Grossly, the tumors ranged in size from 4 to 6 cm and were white and solid; in two tumors necrosis was apparent. Histologically, they were characterized by a cellular proliferation composed of small cells with round nuclei and inconspicuous nucleoli.
