Increasing lymphatic microvessel density in primary pterygia.
OBJECTIVE To examine lymphatic microvessel density (LMVD) in primary pterygia. METHODS We included tissue samples from 88 excised primary (including 34 grade 1, 28 grade 2, and 26 grade 3) pterygia and from 7 nasal epibulbar conjunctivae segments used as control samples. Sections from each pterygium were immunostained with CD31 and lymphatic vessel endothelial hyaluronan receptor 1 (LYVE-1) m...
متن کاملLymph node reactivity and microvessel density in neck metastases of unknown primary squamous cell carcinoma.
BACKGROUND Neoangiogenesis and the immune response are important mechanisms in metastasis development. AIM to evaluate lymph node reactivity and microvessel density in neck metastasis of occult primary squamous cell carcinoma considering their histological and clinical variables. STUDY DESIGN retrospesctive case-series. METHOD 19 patients with neck metastasis of occult primary squamous ce...
متن کاملPrediction of Primary Tumors in Cancers of Unknown Primary.
A cancer of unknown primary (CUP) is a metastatic cancer for which standard diagnostic tests fail to identify the location of the primary tumor. CUPs account for 3-5% of cancer cases. Using molecular data to determine the location of the primary tumor in such cases can help doctors make the right treatment choice and thus improve the clinical outcome. In this paper, we present a new method for ...
متن کاملMicrovessel density and CpG island methylation of the THBS2 gene in malignant ovarian tumors.
We aimed to investigate the role of thrombospondin-2 (THBS2) related angiogenic activity in malignant ovarian tumors and to determine if aberrant methylation associated inactivation is involved in down-regulating THBS2 expression in ovarian cancer. The methylation status of the THBS2 promoter region and microvessel density (MVD) was studied in 70 malignant ovarian tumors and in 15 control ovari...
متن کاملCorrelation between CT Perfusion Parameters and Microvessel Density and Vascular Endothelial Growth Factor in Adrenal Tumors
We evaluated the correlation between computed tomography (CT) perfusion parameters and markers of angiogenesis in adrenal adenomas and non-adenomas to determine if perfusion CT can be used to distinguish between them. Thirty-four patients with pathologically-confirmed adrenal tumors (17 adenomas, 17 non-adenomas) received CT perfusion imaging before surgery. CT perfusion parameters (blood flow ...
