Two types of endometrial carcinoma are distinguished with respect to biology and clinical course. Type-I carcinoma is related to hyperestrogenism by association with endometrial hyperplasia, frequent expression of estrogen and progesterone receptors and younger age, whereas type-II carcinoma is unrelated to estrogen, associated with atrophic endometrium,(More)
BACKGROUND The two most common types of uterine endometrial carcinoma, endometrioid (UEC) and serous (USC), differ in their histopathologic appearance and biologic behavior. Recent studies suggest that these differences may be associated with distinct molecular genetic alterations. METHODS In the current study, the authors compared the frequencies of(More)
BACKGROUND Several studies have demonstrated the biologic and therapeutic significance of estrogen and progesterone receptors (ER and PR) in breast carcinomas. The aim of the current study was to examine the presence of androgen receptors (AR) in breast carcinomas. METHODS Two hundred cases of breast carcinoma, consisting of 145 invasive and 55(More)
It is assumed that HER-2/neu status remains consistent in breast carcinoma during metastatic spread, but in most previous studies primary tumours were compared with concurrent regional lymph node metastases. The present study investigated 31 breast carcinomas and their corresponding lymph node and distant metastases for HER-2/neu status by(More)
Only five patients found to have brain metastasis preceding the diagnosis of endometrial cancer have been reported in the literature, and none of these survived beyond 38 months. The authors report on two patients with primary endometrial cancer who initially presented with cerebral metastasis. One of these patients died of disease 15 months after(More)
One of the current knowledge gaps in the evaluation of risk for human exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is the relationship between gene expression induced by TCDDmore complex biological responses such as altered growth, differentiation, and neoplasia. This study investigates the dose-dependent expression of CYP1A1, CYP1A2,CYP1B1 in the(More)
This study was designed to analyze certain clinicopathological features and the profile of p53, Ki-67, estrogen (ER), and progesterone (PR) receptor expression of clear cell carcinoma of the endometrium and to determine whether the pathogenesis of clear cell carcinoma can be accommodated by a dualistic model of endometrial carcinogenesis. In this model,(More)
PURPOSE The objective of our study was to determine the clinical relevance of cyclin D1 expression in hormone receptor-positive breast cancer patients who were treated with tamoxifen-based therapy. EXPERIMENTAL DESIGN We assessed expression of cyclin D1 in surgical specimens of breast carcinoma by means of immunohistochemistry. Patients had been enrolled(More)
Circulating tumor cells (CTC) released into blood from primary cancers and metastases reflect the current status of tumor genotypes, which are prone to changes. Here, we conducted the first comprehensive genomic profiling of CTCs using array-comparative genomic hybridization (CGH) and next-generation sequencing. We used the U.S. Food and Drug(More)
AIMS miR-181a expression is frequently altered in different types of cancer. Members of the Wnt/β-catenin signalling pathway, which is commonly altered in colorectal cancer (CRC), have been reported as molecular interaction partners of miR-181. However, the role of miR-181a expression in CRC and its ability to predict survival and response to agents(More)
