BACKGROUND: Exfoliated endometrial cells can be seen in cervical smears in association with a wide variety of conditions ranging from normal proliferative endometrium to endometrial malignancies. It is often difficult to differentiate between benign, atypical and malignant endometrial cells using cytomorphology alone. This study was conducted to evaluate if morphometric analysis of endometrial nuclei on liquid-based cervical samples could be of help in differentiating between these endometrial cells...

A 38-yr-old woman, with a previous history of low grade squamous intraepithelial lesion in the cervix, presented with heavy menstrual bleeding. At hysteroscopy, a fundal polyp was removed from the right cornu which displayed many glands lined by atypical, mitotically active epithelium with features characteristic of endocervical adenocarcinoma in situ (AIS) of intestinal subtype. Subsequent cervical liquid-based cytology and colposcopically directed biopsies revealed no causative lesion, but residual PreservCyt from the ThinPrep vial tested positive for high risk HPV type other than HPV 16 and 18...

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...

OBJECTIVES: Endometrial cytology offers a reliable alternative to biopsy in endometrial cancer detection and it may be useful in obtaining material to study prognostic and predictive markers. Over the years, new sampling devices have been developed. Molecular alterations in endometrial cancers were previously described using formalin-fixed paraffin-embedded tissues with particular attention, in endometrioid carcinomas, to the PTEN-PI3K pathway. PTEN evaluation could be useful in endometrial carcinomas for selecting patients for target therapies...

Endometrial carcinoma (EC) is the leading female genital tract malignancy in industrialized countries. It will become an important public health problem in the coming years in the USA and Europe, where its incidence is increasing, and next-generation interventions should include periodical screening in high-risk women. In this review, we discuss the importance to gynaecologists of detecting women at high risk and offering an adequate screening programme. Screening for EC is particularly challenging and there is currently no proven programme for the surveillance of women estimated to be at an increased risk of developing this form of cancer...

'The objective of this study is to investigate the potential of classification and regression trees (CARTs) in discriminating benign from malignant endometrial nuclei and lesions. The study was performed on 222 histologically confirmed liquid based cytological smears, specifically: 117 benign cases, 62 malignant cases and 43 hyperplasias with or without atypia. About 100 nuclei were measured from each case using an image analysis system; in total, we collected 22783 nuclei. The nuclei from 50% of the cases (the training set) were used to construct a CART model that was used for knowledge extraction...

OBJECTIVE: The removal of blood components is necessary to improve the quality of the liquid-based cytology (LBC) preparations. In ThinPrep® (TP) samples a cell suspension in a methanol-based fixative undergoes a vacuum filtration method, whereas in SurePath™ (SP) samples a cell suspension in an ethanol-based fixative is processed through a density gradient centrifugation system prior to gravity deposition of the specimen onto a glass slide. We compared the cyto-architectural features for the cytologic diagnosis of endometrial adenocarcinoma using parallel TP and SP preparations in a previous publication...

We compared the cytoarchitectural features used for the cytologic diagnosis of endometrial adenocarcinoma (EC) using ThinPrep® (TPS = ThinPrep Sample) and BD SurePath™ (SPS = SurePath Sample) preparations. In 20 patients, a direct endometrial sample using the Uterobrush was obtained. Nineteen cases of EA and one case of carcinosarcoma were studied. TPS and SPS were performed according to the manufacturer's recommendations. Moreover, after the TPS preparation, the residual material was also used to prepare an SPS sample (TP-SPS = ThinPrep-Surepath sample)...
