PURPOSE We examined the frequency, tumor characteristics, and prognostic impact of HER2 protein expression and gene amplification in patients with curatively resected esophageal adenocarcinoma (EAC). EXPERIMENTAL DESIGN HER2 expression was analyzed by immunohistochemistry (IHC) in surgical EAC specimens (n = 713). Gene amplification was examined by FISH(More)
Inflammatory myofibroblastic tumor of the urinary bladder is an unusual spindle cell neoplasm that displays cytologic atypia, infiltrative growth and mitotic activity mimicking malignant tumors, such as leiomyosarcoma, rhabdomyosarcoma and sarcomatoid carcinoma. The objective of this study was to determine if anaplastic lymphoma kinase (ALK-1) protein(More)
To the Editor: We read with interest the recent description by Mariño-Enrı́quez and Fletcher1 of angiofibroma of soft tissue, a novel, highly vascular, benign fibroblastic soft tissue neoplasm. We wish to report an additional case of this distinctive new entity, initially diagnosed on a core needle biopsy and subsequently confirmed morphologically and(More)
The purpose of this study was to clarify the neurogenesis of thalamically evoked gamma frequency (approximately 40 Hz) oscillations in auditory cortex by comparing simultaneously recorded extracellular and intracellular responses elicited with electrical stimulation of the posterior intralaminar nucleus of the thalamus (PIL). The focus of evoked gamma(More)
SPOP mutations and TMPRSS2-ERG rearrangements occur collectively in up to 65% of human prostate cancers. Although the two events are mutually exclusive, it is unclear whether they are functionally interrelated. Here, we demonstrate that SPOP, functioning as an E3 ubiquitin ligase substrate-binding protein, promotes ubiquitination and proteasome degradation(More)
PURPOSE Findings from the human epidermal growth factor receptor 2 (HER2) -positive National Surgical Adjuvant Breast and Bowel Project (NSABP) B31 trial suggested that MYC/HER2 coamplification (> 5.0 copies/nucleus) was associated with additional benefit from adjuvant trastuzumab in patients with early-stage breast cancer. To further explore this(More)
A subset of renal cell carcinomas shows TFEB overexpression secondary to MALAT1-TFEB gene fusion. As alternate mechanisms of TFEB overexpression are likely to have the same effect, we sought to determine the frequency of amplification of TFEB and the adjacent VEGFA gene at 6p21.1. As patients with metastatic renal cell carcinomas are managed with anti-VEGF(More)
Gleason score 7 (GS7) prostate cancer [tumors with both Gleason patterns 3 (GP3) and 4 (GP4)] portends a significantly more aggressive tumor than Gleason score 6 (GS6). It is, therefore, critical to understand the molecular relationship of adjacent GP3 and GP4 tumor cell populations and relate molecular abnormalities to disease progression. To decipher(More)
It has been reported that Fuhrman grading is not appropriate for chromophobe renal cell carcinoma (RCC). The objective of this study was to determine whether nucleolar grading and the recently described chromophobe RCC grading system by Paner and colleagues provide prognostic information. Pathologic features of 185 patients with chromophobe RCC treated(More)
Pleomorphic hyalinizing angiectatic tumor (PHAT) is a rare, locally aggressive tumor of the distal extremities with a proclivity for local recurrence. PHATs contain characteristic ectatic, thin-walled vessels, lined by fibrin, and are surrounded by groups of variably pleomorphic spindled to epithelioid neoplastic cells. The putative precursor lesion of(More)
