Endometrial Cancer Testing with Vaginal and Endometrial Cell Samples

Overview

Información sobre este estudio

Background:

Endometrial cancer is one of the most common gynecologic cancers. If it is caught at an early stage, it can be treated more easily. Women who have this type of cancer often have a history of irregular menstrual bleeding. They may also have abnormal findings during gynecologic exams. Pap smears and cervical cell collection may be able to collect cell samples for cancer testing. However, samples from the vagina or endometrium may produce more accurate results. Researchers want to collect vaginal and endometrial cell samples to improve their tests for and understanding of endometrial cancer.

Objectives:

To collect vaginal and endometrial cell samples to study endometrial cancer.

Eligibility:

Women at least 18 years of age who have had symptoms of abnormal uterine or post-menopausal bleeding, or abnormal ultrasound findings.

Design:

Participants will be screened with a physical exam and medical history.
Participants will have a pelvic exam. Before the exam, they will insert a small tampon in the vagina. The tampon will stay in place for about 10 to 30 minutes. The tampon will then be removed and collected for the study.
During the pelvic exam, tissue will be collected from the uterine lining with a special brush. An additional sample (biopsy) will be collected from the lining.
A blood sample will also be collected as part of the study.

Elegibilidad para la participación

Los requisitos de elegibilidad de los participantes incluyen la edad, el sexo, el tipo y el estadio de la enfermedad, y los problemas de salud o tratamientos previos. Las pautas difieren de un estudio a otro e identifican quiénes pueden o no pueden participar. No hay garantía de que cada persona elegible que desee participar en un ensayo se inscribirá.

Inclusion Criteria:

Women should meet at least one of the following criteria:

Abnormal uterine bleeding
Postmenopausal bleeding
Thickened endometrial stripe
Hereditary predisposition to endometrial cancer (e.g. HNPCC)
Women referred for endometrial biopsy to evaluate suspicion or high risk of endometrial cancer

Exclusion Criteria:

Endometrial carcinoma is the most distressing cause of abnormal vaginal bleeding. The intention of clinical management in the case of postmenopausal bleeding is to achieve an accurate diagnosis without overinvestigation. Read More on PubMed

Classifying endometrial hyperplasia (EH) according to the severity of glandular crowding (simple hyperplasia (SH) vs complex hyperplasia (CH)) and nuclear atypia (simple atypical hyperplasia (SAH) vs complex atypical hyperplasia (CAH)) should predict subsequent endometrial carcinoma risk, but data on progression are lacking. Our nested case-control study of EH progression included 138 cases, who were diagnosed with EH and then with carcinoma (1970-2003) at least 1 year (median, 6.5 years) later, and 241 controls, who were individually matched on age, date, and follow-up duration and counter-matched on EH classification. After centralised pathology panel and medical record review, we generated rate ratios (RRs) and 95% confidence intervals (CIs), adjusted for treatment and repeat biopsies. With disordered proliferative endometrium (DPEM) as the referent, AH significantly increased carcinoma risk (RR=14, 95% CI, 5-38). Risk was highest 1-5 years after AH (RR=48, 95% CI, 8-294), but remained elevated 5 or more years after AH (RR=3.5, 95% CI, 1.0-9.6). Progression risks for SH (RR=2.0, 95% CI, 0.9-4.5) and CH (RR=2.8, 95% CI, 1.0-7.9) were substantially lower and only slightly higher than the progression risk for DPEM. The higher progression risks for AH could foster management guidelines based on markedly different progression risks for atypical vs non-atypical EH. Read More on PubMed
