submucosal dissection, and local surgical excision, including transanal excision and transanal endoscopic microsurgery (TEM). In a study by Kim et al. [6], the complete resection rate for TEM was over 97%. Although TEM is superior to other endoscopic procedures, TEM must be considered to be more invasive because of the risk associated with the use of anesthesia. Third, guidelines for follow-up ...
متن کاملChromosome abnormalities in pediatric brain tumors.
Recurrent, site-specific chromosome translocations and other cytogenetic abnormalities are being described in ever-increasing numbers and types of human tumors. Primary brain tumors are the most common pediatric solid tumor and differ from those of adults in both histology and clinical behavior. We examined chromosomes from 21 primary pediatric brain neoplasms grown in short-term tissue culture...
متن کاملCarcinoid tumors.
Carcinoid tumors are rare, slow-growing neuroendocrine neoplasms that often are indolent and may not become clinically apparent until there has been metastatic spread or evidence of carcinoid syndrome. Recent evidence has revealed that the overall incidence of carcinoid tumors has been steadily increasing, and although the disease was thought to be relatively benign, it is now considered one of...
متن کامل[Chromosome abnormalities caused by computer video display monitors' radiation].
OBJECTIVE Concerns were raised about the potential damaging effects of electromagnetic field (EMF) radiation emissions of ELF (extremely low frequency) and VLF (very low frequency) computer video display monitors (VDM), it was assessed the frequency of structural chromosome abnormalities and investigated the cell cycle kinetics in individuals occupationally exposed to VDM radiation. METHODS C...
متن کاملGenetic alteration in carcinoid tumors of the lung.
Surgically resected specimens of 13 carcinoid tumors of the lung including nine typical carcinoids and four atypical carcinoids, and eight salivary gland type carcinomas (six mucoepidermoid carcinomas and two adenoid cystic carcinomas) were analyzed regarding p53 expression, loss of heterozygosity (LOH) in chromosome 3p, 9p, and K-ras mutation. The overexpression of p53 was identified in four a...
