Encapsulated follicular variant papillary thyroid carcinomas (EFVPTC) are quite slow (indolent). Non-invasive follicular thyroid neoplasm with papillary nuclear feature (NIFTP) is a new entity identified as a result of studies in recent years. If the patient instead of EFVPTC develops NIFTP, cancer will not be recognized and the treatment will change. Three groups, in which CD44, p53, Ki-67, p27, HBME-1, galectin-3, cytokeratin-19, CD56 were used as markers, were evaluated. Nuclear score assessment was also conducted in the NIFTP group. The results were compared with each other. Significant differences were detected in the intensities and percentages of CK19, HBME-1, CD56, CD44 staining and galectin-3 staining intensity. In group 1, cytokeratin-19, galectin-3, HBME-1 and CD44 expression were not as low as in the other groups, while CD56 staining was detected more frequently. p53, p27 and Ki-67 staining showed no obvious expression differences between the groups. The NIFTP group showed different IHC results compared to encapsulated invasive FVPTC and common invasive FVPTC. When evaluating whether the IHC expression patterns used in PTCs differ in NIFTP cases, it was found that CD44 could serve as an additional IHC stain that may guide pathologists during the diagnosis.","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":"75 4","pages":"315-323"},"PeriodicalIF":0.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030229","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}

Although such NENs have similar grades, they may exhibit quite different behaviors. In this multicenter study, we aimed to investigate the prevalence and distribution of different morphological NEN variants in the non-pancreatic gastrointestinal (GI) tract and determine whether they can guide prognosis prediction. Two hundred and fifty-six patients diagnosed with NENs originating from the GI tract from 7 different centers were included in the study. In 89 (36.6%) cases, different morphological variants were detected. When the variants were grouped according to their aggressiveness as described in the literature, a statistically significant relationship between aggressiveness and the variables organ and age was found ( p < 0.05). The oncocytic variant was found to metastasize more than the other aggressive types (42.9%). The paraganglioma-like variant was found to have a smaller size, lower proliferation index, and a more benign clinical course. This study demonstrated that well-differentiated GI neuroendocrine tumors (GI-NETs) have considerable morphological diversity. Generally, case reports of rare morphological variants of GI-NETs are available in the literature. We believe that our study contributes to a better understanding of the prevalence, localization, and significance of morphological variations in GI-NETs.","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":"75 2","pages":"126-137"},"PeriodicalIF":0.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142019323","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}

Clinical data of 151 women who underwent BRCA1/2 gene testing at Mersin University Medical Faculty Hospital between 2016 and 2019 were retrospectively analyzed. BRCA1/2 variants were detected as pathogenic (n = 11), variants of uncertain significance (n = 5), likely benign (n = 3), and benign (n = 81) in breast cancer cases. The BRCA1/2 pathogenic variant carriers had a higher histological grade, rate of triple- negative type, Ki-67 proliferation index, and rate of no special type carcinoma than the group without mutation (p = 0.03, 0.01, 0.04, and 0.02 respectively). We analyzed the distribution of variants we detected in women living in our region and found that pathogenic variants in patients with breast cancer were associated with high histological grade, triple-negative type, high Ki-67 proliferation index, and histological type.

However, the role of LRP16 in endometrial carcinoma remains to be explored. We aimed to investigate the prognosis and role of LRP16 in endometrial carcinoma. Overall, 160 endometrial carcinoma (EC) tissues and 60 benign samples were collected. The expression of LRP16 protein in EC tissues was significantly increased compared with that in normal endometrial tissues, and high LRP16 expression was related to poor patient prognosis. Reduced LRP16 expression markedly inhibited cancer cell growth. The proliferation rates in the prophylactic bilateral salpingectomy (PBS) group and the shNon group were 0.727 ±0.015 and 0.743 ±0.009, respectively, while the proliferation rate in the shLRP16 group was only 0.373 ±0.012. The migration experiment showed that the number of cells passing through the basement membrane in the shLRP16 group was 34.2 ±5.1, which was significantly different to the shNon (161.6 ±7.8) and PBS groups (138.0 ±7.2). The results of the invasion experiment showed that the number of cells was 39.2 ±6.2 in the shLRP16 group, 146.7 ±8.2 in the shNon group, and 141.2 ±8.1 in the PBS group ( p < 0.05).

In the current study, the frequency of programmed death ligand 1 (PD-L1) expression in SCLC and its correlation with clinico-pathological features were evaluated. The study included 100 cases of SCLC wherein testing for PD-L1 was done with the SP263 clone on the Ventana benchmark XT system. Cases with > 1% PD-L1 expression in tumour cells or immune cells were categorized as positive. PD-L1 expression was identified in 14% of cases using the cut-off of ≥ 1%. The tumour proportion score was 10% and the immune proportion score was 9.78% using a cut-off of ≥ 1%. PD-L1 positive expression was more frequent in the male population with age > 40 years. All the patients with positive PD-L1 expression were smokers. In the PD-L1 positive group, presence of necrosis was identified in 71.4% of cases and when compared with the PD-L1 negative subgroup this finding was statistically significant (p = 0.010). Personalized targeted therapy for cases of SCLC is still under evaluation. The use of immunotherapeutic targets, such as PD-L1, may help to define a new treatment strategy for SCLC. Development of new treatment strategies may improve prognosis and survival.","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":"75 1","pages":"25-35"},"PeriodicalIF":0.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141162621","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}
