BACKGROUND The role of frozen section (FS) in intraoperative decision making for surgical staging of endometrial cancer is controversial. Objective of this study is to assess the agreement rate between the FS and paraffin section (PS); and the potential impact of the role of FS in the intra-operative decision making for the complete surgical staging in low(More)
BACKGROUND Cervical adenocarcinomas (ADC) have been viewed as more aggressive than squamous cell carcinoma (SCC). We analyzed an international cohort of early stage cervical cancer to determine the impact of histologic type. METHODS Retrospective analysis of patients with SCC (148 patients) and ADC (130 patients) stages IA1-IB2 who underwent surgery at(More)
The literature on the clinicopathologic characteristics of tumoral intraepithelial neoplasms (neoplastic polyps) of the gallbladder (GB) is fairly limited, due in part to the variability in definition and terminology. Most reported adenomas (pyloric gland type and others) were microscopic and thus regarded as clinically inconsequential, whereas papillary in(More)
Genetic aberrations, such as loss of heterozygosity (LOH) and mutations leading to functional inactivation of the PTEN tumor suppressor gene, located on chromosome 10q23.3, have been shown to be associated with approximately one third of ovarian adenocarcinomas. In addition, microsatellite instability (MSI) leading to the functional inactivation of the PTEN(More)
OBJECTIVE The objective of the study was to evaluate the prognosis of ovarian cancer arising in endometriosis. STUDY DESIGN We retrospectively compared 42 cases of endometriosis-associated ovarian cancer (EAOC) with 184 cases of ovarian carcinoma without endometriosis (OC). RESULTS The median age in the EAOC group was 52 vs 59 years in OC (P < .05). In(More)
The polycomb group protein, enhancer of zeste homolog 2, is a transcriptional repressor involved in cell cycle regulation and has been linked to aggressive breast cancer. We examined the clinical and biological significance of enhancer of zeste homolog 2 expression in triple-negative breast cancers. Tissue microarrays were constructed with invasive breast(More)
OBJECTIVE The deregulation of E-cadherin is associated with Src/FAK signaling axis and histone deacetylase (HDAC)/EZH2 activity. However, the association between EZH2 and FAK and its clinical significance in endometrial carcinoma has not been reported. METHODS 202 archived cases of endometrial carcinoma (1996-2000) were reviewed and divided into two(More)
OBJECTIVE Although microstellite instability (MSI) is a prognostic marker in colorectal cancer, it's relation with prognosis in the endometrial cancer is controversial. The goal of this study is to identify the correlation between MSI and clinicopathologic markers along with survival in high grade endometrial carcinoma EC. METHODS Between 1995 and 2004,(More)
Ampullary (AMP) carcinomas comprise a heterogeneous group of cancers lacking adequate subcategorization. In the present study, 249 strictly defined primary AMP carcinomas (ACs) identified in 1469 malignant pancreatoduodenectomy specimens were analyzed for defining features. Gross and microscopic findings were used to determine tumor epicenter and extent of(More)
Prognostication of invasive ampullary adenocarcinomas (AACs) and their stratification into appropriate management categories have been highly challenging owing to a lack of well-established predictive parameters. In colorectal cancers, recent studies have shown that tumor budding confers a worse prognosis and correlates significantly with nodal metastasis(More)
