OBJECTIVE: Previous studies suggest that differences in molecular features of endometrial cancers between racial groups may contribute to the poorer survival in Blacks. The objective of this investigation was to determine whether gene expression among endometrial cancers is different between Blacks and Whites. METHODS: Fresh frozen tumors from 25 Black patients were matched by stage, grade, and histology to endometrial cancer specimens from 25 White patients. Each case was macrodissected to produce specimens possessing a minimum of 75% cancer cellularity...

Endometrial cancer, one of the most common gynecologic malignancies, is increasing in Japan, nearly doubling over the last decade. High-grade disease patients are often resistant to conventional chemotherapy with platinum agents; therefore, discovery of efficacious new drugs in this setting is required to benefit chemorefractory cases. The 50% growth-inhibitory (GI50) concentration of 27 clinically relevant drugs was measured in the NCI60 panel of cell lines. Gene expression data were analyzed using Bayesian binary regression, to first generate a response signature for each drug and then to calculate individual susceptibility scores using in vivo endometrial cancer data (GSE2109; http://www...

OBJECTIVE: Endometrial cancer patients may benefit from systemic adjuvant chemotherapy, alone or in combination with targeted therapies. Prognostic and predictive markers are needed, however, to identify patients amenable for these therapies. METHODS: Primary endometrial tumors were genotyped for >100 hot spot mutations in genes potentially acting as prognostic or predictive markers. Mutations were correlated with tumor characteristics in a discovery cohort, replicated in independent cohorts and finally, confirmed in the overall population (n=1063)...

Diffuse p53 immunostaining distinguishes 85% of serous (Type II) from endometrioid (Type I) carcinomas and is an independent marker for poor prognosis. Interobserver reproducibility for the diagnosis of these entities, as well as selection and prediction of p53 immunostaining results, is unknown. Reproducibility of three pathologists regarding: (1) a two (I and II) and (2) three part classification (I, II or indeterminate); (3) recommendation for p53 staining and (4) expectations of p53 staining results were computed with the kappa (k) statistic...

PURPOSE: Endometrial cancer is the most common gynecologic malignancy. Established prognostic factors are histologic grade, depth of myometrial invasion, and extrauterine spread including retroperitoneal lymph node metastases. Tumorigenesis is a multistep process involving different genetic changes resulting in uncontrolled cellular proliferation, inhibition of apoptosis, and enhanced vascular proliferation among other events. Angiogenesis, the formation of new blood vessels from a preexisting vascular network, is necessary for invasive tumor growth and metastasis and constitutes an important point in the control of cancer progression...

OBJECTIVE: A binary grading system has been proposed to assess the amount of solid growth, the pattern of invasion, and the presence of necrosis, and thereby divide endometrial endometrioid carcinomas into low- and high-grade tumors. We analyzed this system for predicting the prognosis, with respect to inter- and intraobserver reproducibility and treatment modalities. METHODS: A total of 200 endometrial carcinomas, based on hysterectomy specimens, were graded according to the binary grading system, for comparison against The International Federation of Gynecology and Obstetrics (FIGO) system and nuclear grading...

Routine dilatation and curettage (D&C) in all patients with postmenopausal bleeding (PMB) is debatable, as 70%-80% will eventually receive benign diagnoses. Endometrial thickness (ET) measurements by transvaginal ultrasonography (TVUS) are used with high sensitivity to detect patients who would benefit from D&C, yet they suffer from low specificity that fails to reduce undue invasive procedures. The aim of this study was to define optimal cutoffs for ET in diagnosing endometrial pathologies in PMB and to assess a possible complementary role for Doppler ultrasonography...
