After the COVID-19 pandemic, changes occurred in the number and content of pathology laboratory samples, related to measures such as reducing the number of outpatient clinics in hospitals, postponing elective surgery, and restricting cancer screening. All samples sent to the pathology laboratory between 2019 and 2020 were included in our study. Biopsy, cytology, histochemical, and immunohistochemical staining and biopsies for malignant cases were evaluated. Changes in sample number and content caused by the pandemic were examined. The number of biopsies was 24 312 in 2019 and 13 208 in 2020. On comparison, a decrease was observed in all parameters. The largest (78.5%) and smallest (11.02%) decreases were observed in examinations of the incoming preparations for consultation (214-46) and Trucut needle biopsies (726-646), respectively. Cases such as appendectomies that require urgent intervention and malignancies that require further examination and diagnosis are the least affected. However, whether the decrease in cancer screening will affect the early diagnosis and treatment of malignancies and create a public health problem in the future remains to be established.","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41162408","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}

Its incidence rate is one of the fastest growing tumors in China. The Krüppel-like factor 6 (KLF6) is a latent tumor suppressor. Decreased KLF6 is related to the occurrence and progression of many cancers in human. Our previous studies have demonstrated that KLF6 was down-regulation in cutaneous malignant melanoma (CMM), and was significant correlated with ulcer, lymph node metastasis and clinical stage, suggesting that KLF6 loss is expected to become a biological indicator of poor prognosis in CMM patients. In this research, we would further study the features of KLF6 in the malignant progression of CMM. The expression of KLF6 was up-regulated by lentivirus infection containing KLF6, and short hairpin RNA (shRNA) was used for knockdown of KLF6 in CMM cells. Western blot, RT-qpcr, CCK8 assay, transwell migration assays, wound healing assay and flow cytometry were used to test the role of KLF6 in the CMM. We found that reduced expression of KLF6 significantly enhanced proliferation, migration and invasion. Moreover, KLF6 induced CMM cell apoptosis and G1 cycle arrest. The decreased KLF6 expression is expected to be a biological indicator of poor prognosis in CMM patients.","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89720246","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}

The purpose of the present study was to validate modifications to stages of the LBC process and to assess the diagnostic usefulness of the LBC technique. Between May 2021 and January 2022, a total of 484 samples were prepared from routine cytology tests carried out in the Department of Tumor Pathology of The Greater Poland Cancer Center. The material was obtained from fine-needle aspiration biopsies and fluid samples. One hundred cases were selected for the research described in the article. The slides were prepared using the Becton Dickinson Totalys SlidePrep device. Based on the research, it was concluded that predominantly the LBC technique gives better results than a conventional smear because the background, which would otherwise make it difficult to assess preparations, was eliminated. Additionally, in LBC preparations the cellularity was increased, and the cells were arranged in a monolayer system, which improves the image quality. The introduction of modifications to the LBC method facilitated the process of sample preparation, without adversely affecting the quality of the obtained material.","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140112001","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}

However, its expression type and clinical relevance in gastric cancer remains unclear. In the present study, mRNA level of OLA1 in gastric cancer (GC) was detected in 2 datasets downloaded from the open Gene Expression Omnibus database and 30 cancer tissues. Immunohistochemistry was performed on GC and its association with Snail in 334 GC patients. The results showed that OLA1 mRNA and protein were elevated in GC tissues. High expression of OLA1 was significantly associated with aggressive features, such as tumour size, lymph-node-metastasis and tumour-nodus-metastases stage ( p = 0.0146, p = 0.0037, p < 0.001, respectively). Moreover, high levels of OLA1 predicted worse overall survival. Multivariate Cox regression analysis indicated that high expression of OLA1 was an independent prognostic factor for poor overall survival ( p = 0.009). Additionally, OLA1 expression was positively correlated with Snail, and a combination of them revealed improved prognostic accuracy for GC patients. High expression of OLA1 predicts poor prognosis in GC patients and may be serviced as a novel target for GC.","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9667663","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}

The current study aimed to investigate whether CD98 can be used as a prognostic factor and marker of radioresistance. CD98 immunostaining was performed using biopsy specimens collected from patients diagnosed with HNSCC. The average period of postoperative monitoring was 31.6 months. The treatment options were radiation therapy with either cisplatin or cetuximab, and surgery. The participants were divided into groups of low and high fluorescence intensity. CD98 was an independent prognostic factor of radioresistance. In total, 103 patients were treated with chemoradiotherapy or bioradiotherapy. The overall survival rates of patients receiving chemoradiotherapy or bioradiotherapy were 69.2% in the low group and 36.2% in the high group. The progression-free survival rates were 60.0% and 24.6%, respectively. CD98 expression was considered an independent prognostic factor of overall survival and progression-free survival. In total, 99 patients underwent surgical treatment. The surgery group did not differ according to CD98 expression. Via CD98 immunostaining, sensitivity to radiotherapy can be determined in advance. In HNSCC, knowledge about sensitivity to radiotherapy can significantly improve prognosis.","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41157503","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}

Overexpression of HER2 protein determined by immunohistochemistry (IHC) or amplification of the HER2 gene determined by fluorescence in situ hybridization (FISH) is a condition for qualifying patients for anti-HER2 therapy. Due to the high toxicity of anti-HER2 treatment, proper patient selection is essential. In our study we compared 40 cases with IHC staining of HER2 antibody determined by Ventana PATHWAY anti-HER2/neu antibody (4B5) as HER2 2+ with the new antibody (HercepTest™ mAb PharmDx [Dako Omnis] [GE001]). Then using a double-blind study we compared the (IHC) evaluation with FISH results. In 65% of cases (26/40) the IHC 2+ score remained unchanged, in 32.5% of cases (13/40) expression of HER2 protein after IHC with new antibody was indicated as 3+ score, and in one case we observed a decrease of HER2 protein expression to 1+. In all cases but one, in which we found IHC HER 3+ with new antibody, there was FISH amplification. We have reason to believe that the new antibody will reduce the diagnostic time and avoid unnecessary costs. Due to the small study group, further investigation is needed.","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41164504","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}
