Abstract Objective The disease specific five-year survival rate especially for patients with advanced oral cancer has not improved significantly over the period of time. most effective way combating this dilemma is an early detection, diagnosis and eradication early-stage lesions their precursors. use VELscope ® using autofluorescence as a diagnostic tool might be useful in detection malignant lesions. Materials methods 120 suspicious premalignant were examined two examination methods. They...
IMP3 is an RNA binding protein required for ribosomal processing, which has been suggested to be a prognostic marker in large variety of human types cancer. However, available data on the prevalence expression are largely discrepant. To systematically investigate epidemiology and clinical relevance cancers we employed two-step tissue microarrays (TMAs) approach. First, normal TMA multi-tumor were analyzed immunohistochemically detectable 76 different 3889 cancer samples from 95 tumor...
Biglycan (BGN), a proteoglycan of the extracellular matrix, is included in mRNA signatures for prostate cancer aggressiveness. To understand impact BGN on prognosis and its relationship to molecularly defined subsets, we analyzed expression by immunohistochemistry tissue microarray containing 12,427 cancers. Seventy-eight percent 11,050 interpretable cancers showed expression, which was considered as low intensity 47.7% high 31.1% protein rose with increasing pathological tumor stage,...
Syndecan-1 (CD138) is a transmembrane proteoglycan known to be expressed in various normal and malignant tissues. It of interest because possible prognostic role differential expression tumors its as target for indatuximab, monoclonal antibody coupled with cytotoxic agent. To comprehensively analyze CD138 neoplastic tissues, we used tissue microarrays (TMAs) analyzing immunohistochemically detectable 2,518 samples from 85 different tumor entities 76 types. The data showed that abundant...
Abstract Background Tumor protein 63 (p63) is a transcription factor of the p53 gene family involved in differentiation several tissues including squamous epithelium. p63 immunohistochemistry broadly used for tumor classification but published data on its expression cancer conflicting. Methods To comprehensively catalogue expression, tissue microarrays (TMAs) containing 12,620 samples from 115 entities and 76 normal types were analyzed. Results was seen various epithelium urothelium. At...
Abstract Background Cytokeratin 18 (CK18) is an intermediate filament protein of the cytokeratin acidic type I group and primarily expressed in single-layered or “simple” epithelial tissues carcinomas different origin. Methods To systematically determine CK18 expression normal cancerous tissues, 11,952 tumor samples from 115 types subtypes (including carcinomas, mesenchymal biphasic tumors) as well 608 76 tissue were analyzed by immunohistochemistry a microarray format. Results was cells...
Abstract Background The E-Cadherin gene ( CDH1, Cadherin 1 ), located at 16q22.1 encodes for a calcium-dependent membranous glycoprotein with an important role in cellular adhesion and polarity maintenance. Methods To systematically determine protein expression normal cancerous tissues, 14,637 tumor samples from 112 different types subtypes as well 608 of 76 tissue were analyzed by immunohistochemistry microarray format. Results was strongly expressed epithelial cells most organs. From 77...
Expansion of CD8+ cytotoxic Tlymphocytes is a prerequisite for anti-cancer immune activity and has gained interest in the era checkpoint therapy.To understand T cell dynamics tumor microenvironment, we used multiplex fluorescence immunohistochemistry to quantitate proliferation (Ki67 co-expression) tissue microarrays from 1107 colorectal, 642 renal cell, 1066 breast, 375 ovarian, 451 pancreatic 347 gastric cancer samples.The density percentage proliferating (Ki67+) cells were both highly...
Combined analysis of cytokeratin 7 (CK7) and 20 (CK20) is often used for assessing the origin metastatic cancer. To evaluate diagnostic utility CK7 CK20, tissue microarrays containing 15,424 samples from 120 different tumor types subtypes 608 76 normal were analyzed by immunohistochemistry. positivity was seen in 52% (8.7% weak, 5.9% moderate, 37% strong) CK20 23% (5.1% 3.4% 15% interpretable tumors. Of 8390 positive tumors, 1181 (14%) showed 5380 (64%) alone, 1829 (22%) alone. predominated...
The Ki-67 labeling index (Ki-67 LI) is a strong prognostic marker in prostate cancer, although its analysis requires cumbersome manual quantification of immunostaining 200-500 tumor cells. To enable automated LI assessment routine clinical practice, framework for quantification, which comprises three different artificial intelligence steps and an algorithm cell-distance multiplex fluorescence immunohistochemistry (mfIHC) staining, was developed validated cohort 12,475 cancers. impact the...
