OBJECTIVE: Early detection and diagnosis of endometrial carcinoma and precancerous change would undoubtedly become the most alluring part for researchers. With the emergence of endometrial brush samplers, a new upsurge in endometrial cytology is in the making. But endometrial specimens obtained by the endometrial brush samplers require special preservation solution. The objective of this study is to develop a new kind of endometrial-cell preservation solution and to test the availability compared with a patented liquid-based cell preservation solution...

PURPOSE: Endometrial carcinoma is the most common gynecologic malignancy in both developed and some developing countries. Unlike cervical cancer, for which there is routine screening, only patients symptomatic for endometrial carcinoma typically seek medical help for its diagnosis and treatment. Dilatation and curettage (D&C) has been the standard procedure for evaluating suspicious endometrial lesions. The discomfort and injury caused by the D&C procedure, however, restrict its use as a screening method for early diagnosis of endometrial lesions...

Cervical sample is routinely taken to identify squamous dysplastic lesions of the cervix. Glandular lesions are far less commonly reported on cervical samples. The most common glandular lesion reported on cervical smear is endocervical adenocarcinoma, followed by endometrial adenocarcinoma. Direct sampling by Cervex brush is possible even in endometrial adenocarcinoma, if the tumor directly involves lower uterine segment/endocervical canal. Metastases to cervix are rare but have occasionally been reported in previous reports...

The prognosis of endometrial cancer is strongly associated with stage at diagnosis, suggesting that early detection may reduce mortality. Women who are diagnosed with endometrial carcinoma often have a lengthy history of vaginal bleeding, which offers an opportunity for early diagnosis and curative treatment. We performed DNA methylation profiling on population-based endometrial cancers to identify early detection biomarkers and replicated top candidates in two independent studies. We compared DNA methylation values of 1,500 probes representing 807 genes in 148 population-based endometrial carcinoma samples and 23 benign endometrial tissues...

BACKGROUND: Endometrial cancer is the most common pelvic gynecological malignancy. The diagnosis of well-differentiated endometrial adenocarcinoma, atypical hyperplasia, and hyperplasia is often challenging. The authors sought to investigate the utility of chromosomal anomalies for the detection of endometrial hyperplasia and carcinoma using multitarget fluorescence in situ hybridization (FISH). METHODS: Samples were collected by endometrial Tao brush and processed by liquid-based cytological preparation protocol from consecutive cases to include 50 benign, 50 hyperplasia without atypia, 47 atypical hyperplasia, and 53 endometrial cancers...

The number of new cervical adenocarcinoma (AD) cases has risen slowly, however, its histological similarity to other tumor types and the difficulty of identifying the site of the original tumor makes the diagnosis of cervical AD particularly challenging. We investigated a novel molecular biomarker for cervical AD through the integration of multiple methods of genomic analysis. Tumor samples in discovery set were obtained from 87 patients who underwent radiotherapy, including 31 cervical AD. Microarray analysis and quantitative polymerase chain reaction analysis were performed to screen a candidate diagnostic molecule for cervical AD, and its clinical significance was investigated by immunohistochemical analysis (IHC)...

PURPOSE: The presence of similar histologic subtypes of epithelial ovarian and endometrial cancers has long been noted, although the relevance of this finding to pathogenesis and clinical management is unclear. Despite similar clinical characteristics, histologic subtypes of cancers of the ovary and endometrium are treated according to organ of origin. This study compares the gene expression profiles of analogous histologic subtypes of cancers of the ovary and endometrium using the same genomic platform to determine the similarities and differences between these tumors...

During the past few decades, a variety of diagnostic methods for endometrium direct sampling have been developed. One of these new techniques is endometrial brush biopsy (uterobrush). The principal aim of uterobrush is early detection of endometrial carcinomas and their precursors, but it may be also used to follow up the patients undergoing hormone replacement therapy (HRT). So far, there are only few clinical reports evaluating uterobrush as a technique useful in monitoring endometrial cytology during HRT...

OBJECTIVE: To describe 633 cases using the Tao Brush for endometrial biopsy (EBB) in an outpatient setting. STUDY DESIGN: Histologic follow-up specimens within six months of EBB in an outpatient setting were evaluated over a two-year period. Diagnosis by EBB relied mainly on histologic evaluation of hematoxylin and eosin-stained tissue sections and was complemented by additional cytologic smear examination in our laboratory. Diagnostic categories included the following: nondiagnostic (ND), benign endometrium (BE), hyperplasia without atypia (H), atypia (AT) and atypical hyperplasia (AH)/carcinoma (CA)...
