UNLABELLED Angiogenesis is new blood vessel formation, a process that can lead to tumor development. Microvessel count has been correlated to metastasis in some neoplasias. PURPOSE To determine if measurement of microvessel density is useful in predicting metastasis to the cervical lymph node and prognosis in patients with papillary thyroid carcinoma. METHODS A retrospective analysis was pe...
PURPOSE A computer-assisted microvessel analysis system was developed to evaluate correlations between the architecture of biopsy specimen microvessels and the outcome for patients with esophageal cancer treated with chemoradiotherapy. EXPERIMENTAL DESIGN Biopsy specimens from 51 patients with esophageal cancer (T(2-3), any N, M0) treated with chemoradiotherapy were immunostained with an anti...
To investigate the role of angiogenesis in multiple myeloma (MM), bone marrow biopsy from 75 adults with newly diagnosed, untreated MM were evaluated. Microvessels were scored in at least 3 areas ( x 200 fields) of the highest microvessel density in representative sections of each bone marrow specimen using immunohistochemistry for CD34. Prognostic variables were also evaluated for the overall ...
Angiogenesis is one of the six originally constituted hallmarks of cancer that has been extensively studied in the last two decades. The aim of our study is to assess the microvessel and macrophageal density in laryngeal carcinoma and its clinicopathological correlations. We immunohistochemically assessed microvessel density (CD34) and macrophage count (CD68) using microarray techniques and the...
BACKGROUND Platelet-derived endothelial cell growth factor (PD-ECGF) is known to promote the development of new blood vessels, which are fundamental to tumor growth and metastasis. We previously found that thymidine phosphorylase (dThdPase) and PD-ECGF are the same protein. PURPOSE We retrospectively examined the expression of dThdPase in primary colorectal carcinomas, its association with an...
PURPOSE TSP association with clinicopathological features, including microvessel count, regarding prognostic significance was examined in patients presenting with invasive cervical cancer. EXPERIMENTAL DESIGN Gene expression of TSP-1 and TSP-2 was assessed by reverse transcription-PCR in 10 normal cervix and 78 invasive cervical cancer samples. RESULTS TSP-1 and TSP-2 mRNA expression was de...
