We systematically investigated GLUT1 expression in human papillomavirus (HPV)–associated and HPV-independent vulvar intraepithelial neoplasia (VIN) and SCC. Our study had a total of 240 cases, including 40 cases of non-neoplastic vulva, 45 HPV-associated high-grade squamous intraepithelial lesions (HSILs), 65 HPV-independent VINs, and 90 invasive SCCs. Immunohistochemical analysis revealed that GLUT1 was expressed noncontinuously at the basal layer near stromal papillae in most non-neoplastic vulvar squamous epithelium. Overexpression of GLUT1 was observed in 82.2% and 88.9% of HPV-associated HSIL and SCC, respectively, compared with 96.9% and 100% of HPV-independent VIN and SCC. Two distinct patterns of the GLUT1 expression were observed in HPV-associated and HPV-independent VIN and SCC. In HPV-associated HSIL, overexpression of GLUT1 was mainly noted in the upper intermediate layers, accompanied by negative or weak immunostaining in the basal and parabasal layers. Similar patterns were also found in HPV-associated SCC, characterized by increased GLUT1 staining intensity in the centers of tumor sheets or nests with spared basal peripheral layers. Conversely, intense membranous GLUT1 staining was mainly observed in the basal and suprabasal layers in HPV-independent VIN, regardless of p53 status. Similar intense basal and parabasal GLUT1 staining patterns and no or weak staining intensity in central areas were seen in HPV-independent SCCs. In conclusion, overexpression of GLUT1 was found in most vulvar SCCs and their precursors. We identified 2 distinct GLUT1 patterns between HPV-associated and HPV-independent VINs and SCCs. Given its high sensitivity, immunohistochemistry for GLUT1 can be a valuable tool for facilitating accurate diagnosis of VIN, especially the HPV-independent type.</div></div>","PeriodicalId":18706,"journal":{"name":"Modern Pathology","volume":"38 11","pages":"Article 100836"},"PeriodicalIF":7.1,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144564888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to refine their classification through integrated histopathologic and molecular analyses. We conducted a bicentric retrospective study of 25 cases (15 resections and 10 biopsies). Four liver pathologists independently reviewed histologic and immunohistochemical features. Targeted DNA next generation sequencing and RNA sequencing were performed on 21 and 15 cases, respectively. Seven lesions (28%) were diagnosed as AH, presenting as well-demarcated tumors with fibrotic stroma, often associated with cirrhosis (5/7, 71%). The remaining 18 lesions (72%) were identified as HSVN, typically infiltrative and occurring predominantly in non-cirrhotic livers (78%). Microscopically, HSVN displayed two distinct patterns: (1) a classic pattern (8/18, 44%) composed of small, thin-walled vessels, and (2) a hepatocellular-reactive pattern (7/18, 39%) with small vessels interwoven with regenerative hepatocellular trabeculae. A mixed pattern appeared in 3/18 cases (17%). No cytologic atypia or mitoses were observed. Tumor cells consistently expressed ERG, CD31, and CD34, with Ki67 indices <10% in all cases. Mutations in GNA genes were found in 20 of 21 cases (95%), distributed between GNA14 (81% overall: 4 AH and 13 HSVN, p=0.544) and GNAQ (19% overall: 2 AH and 2 HSVN, p=0.544). Transcriptomic analysis revealed no differentially expressed genes between AH and HSVN. After a median follow-up of 18 months, no recurrence was observed in resected tumors. Tumor growth was noted in three non- or partially resected cases (two AH and one HSVN). In conclusion, despite subtle pathological differences, HSVN and AH exhibit overlapping clinical and molecular features, supporting their reclassification as a single benign entity, namely AH.

In this study, we analyzed the association between CCND1 gain, cyclin D1 immunohistochemistry (IHC), and disease-specific survival (DSS) in a series of patients with HPV-independent VSCC.

All study readers were qualified by completing Agilent training and certification testing specific to the tumor types and cutoffs they scored for the study. Formalin-fixed, paraffin embedded (FFPE) specimens were stained using the qualitative IHC assay, PD-L1 IHC 22C3 pharmDx, on Autostainer Link 48 and scored using the Tumor Proportion Score (TPS) or Combined Positive Score (CPS) algorithm at predefined cutoffs.

However, objective and systematic assessments of fibrosis signatures in colon cancer remain underexplored. This study evaluated the phenotypic histologic features of fibrosis within the tumor, which reflect lymph node (LN) metastasis and predict recurrence, to identify fibrosis signatures in patients with advanced colon adenocarcinoma. Of 499 patients who underwent surgical resection for colorectal cancer, 38 patients with stage T3 colon adenocarcinoma were selected by propensity score matching. Paraffin-embedded tissues were stained with Azan-Mallory and converted to digital pathological images. The histologic phenotypes of fibrosis were quantified based on collagen content and structure in primary tumors using the FibroNest quantitative digital pathology platform. Quantitative fibrosis traits, describing most of the variability between consecutive groups, were integrated into a phenotypic fibrosis composite score (Ph-FCS). Overall, Ph-FCS, which encompasses collagen content, fiber morphology, and fiber structure, differed significantly between the T3 colon cancer with LN metastasis and nonmetastasis groups, distinguishing between the metastasis and nonmetastasis groups with 89.5% sensitivity and 89.5% specificity (area under the curve, 0.95). Among all the parameters, kurtosis, a texture analysis component indicating the concentration of histogram data, was the most significantly different individual factor between the 2 groups. Furthermore, among the 19 patients with LN metastasis, Ph-FCS could distinguish between the recurrence and nonrecurrence groups after chemotherapy with 71.4% sensitivity and 100% specificity (area under the curve, 0.88). Detailed analysis revealed that the number of fiber branches was significantly higher in the recurrence group compared with the nonrecurrence group. In conclusion, among patients with advanced colon cancer who underwent colon surgery, the fibrotic histologic phenotype differed significantly between those with and without LN metastasis, as well as between patients with and without recurrence following chemotherapy.
