Hysteroscopy as a standard procedure for assessing endometrial lesions among postmenopausal women

Abnormal Uterine Bleeding

Abnormal uterine bleeding is a frequent condition in Gynecology. It may impact physical, emotional sexual and professional aspects of the lives of women, impairing their quality of life. In cases of acute and severe bleeding, women may need urgent treatment with volumetric replacement and prescription of hemostatic substances. In some specific cases with more intense and prolonged bleeding, surgical treatment may be necessary. The objective of this chapter is to describe the main evidence on the treatment of women with abnormal uterine bleeding, both acute and chronic. Didactically, the treatment options were based on the current International Federation of Gynecology and Obstetrics (FIGO) classification system (PALM-COEIN). The etiologies of PALM-COEIN are: uterine Polyp (P), Adenomyosis (A), Leiomyoma (L), precursor and Malignant lesions of the uterine body (M), Coagulopathies (C), Ovulatory dysfunction (O), Endometrial dysfunction (E), Iatrogenic (I), and Not yet classified (N). The articles were selected according to the recommendation grades of the PubMed, Cochrane and Embase databases, and those in which the main objective was the reduction of uterine menstrual bleeding were included. Only studies written in English were included. All editorial or complete papers that were not consistent with abnormal uterine bleeding, or studies in animal models, were excluded. The main objective of the treatment is the reduction of menstrual flow and morbidity and the improvement of quality of life. It is important to emphasize that the treatment in the acute phase aims to hemodynamically stabilize the patient and stop excessive bleeding, while the treatment in the chronic phase is based on correcting menstrual dysfunction according to its etiology and clinical manifestations. The treatment may be surgical or pharmacological, and the latter is based mainly on hormonal therapy, anti-inflammatory drugs and antifibrinolytics.

Risks and benefits of hysteroscopy and endometrial sampling as a standard procedure for assessing serendipitous findings of endometrial thickening in postmenopausal women

A retrospective study was undertaken of 35 asymptomatic postmenopausal women undergoing hysteroscopy, dilatation and curettage (H D&C) for an incidental finding of thickened endometrium to assess the rate of significant pathological findings, cost per finding and complication rate of any procedures performed. This study found one case of endometrial adenocarcinoma (1/35; 3%) at an estimated cost per significant finding of $507,116 with an estimated 11.6 complication events per finding.

Capacity of endometrial thickness measurement to diagnose endometrial carcinoma in asymptomatic postmenopausal women: a systematic review and meta-analysis

OBJECTIVES

Measurement of endometrial thickness is an important tool in the assessment of women with postmenopausal bleeding, but the role of endometrial thickness measurement by ultrasound in asymptomatic women is unclear. The aims of this study were to determine: (1) the normal endometrial thickness measured by ultrasonography, (2) the prevalence of serious endometrial pathology and (3) the sensitivity and specificity of endometrial thickness measurement by transvaginal ultrasonography (TVS) for diagnosing premalignant and malignant endometrial disease in asymptomatic postmenopausal women.

METHODS

A MEDLINE and EMBASE search (from inception to January 2011) was performed. Articles reporting on endometrial thickness measurement in the diagnosis of endometrial carcinoma and atypical hyperplasia in asymptomatic postmenopausal women not using hormone replacement therapy (HRT) were selected. Endometrial thickness and the prevalence of endometrial (pre)malignancies were recorded. If possible, 2 × 2 tables were extracted.

RESULTS

Thirty-two studies reporting on 11100 women were included. The estimated mean endometrial thickness was 2.9 mm (95% CI, 2.6-3.3 mm). The pooled estimated prevalences of endometrial carcinoma and atypical endometrial hyperplasia were 0.62% (95% CI, 0.42-0.82%) and 0.59% (95% CI, 0.22-0.96%), respectively. Summary estimates for sensitivity and specificity of TVS endometrial thickness measurement in the prediction of endometrial carcinoma were 0.83 (95% CI, 0.19-1.00) and 0.72 (95% CI, 0.23-0.95) for a 5-mm cut-off and 0.33 (95% CI, 0.04-0.85) and 0.94 (95% CI, 0.92-0.96) for a 6-mm cut-off.

CONCLUSIONS

The results from this systematic review do not justify the use of endometrial thickness as a screening test for endometrial carcinoma and atypical endometrial hyperplasia in asymptomatic postmenopausal women not using HRT.

Advancements in the use of blood tests for cancer screening in women at high risk for endometrial and breast cancer

Several years ago, it was argued that the identification of serum biomarkers is one of the most promising approaches for the detection of early-stage malignant or even premalignant lesions. In this review, the need to establish better monitoring protocols is described for obese women who are at higher risk for the development of malignancies commonly associated with excess weight; specifically endometrial and postmenopausal breast cancer. These cancers have been chosen for this review article as our aim was to focus on female cancers that have been linked with obesity. Cancer screening is essential in detecting disease in its earliest stage in order to reduce morbidity and mortality; however, effective screening is not available for many cancer types. Even for cancers that have effective screening protocols available, there are barriers to screening in obese individuals, such as reduced mobility and embarrassment. These barriers often delay screening in these vulnerable population groups, leading to detection of the disease at a more advanced stage and ultimately leading to a poorer prognosis. As of today, biomarkers do not replace but augment imaging and other existing screening approaches. Future development of blood- or urine-based biomarkers as a way to screen individuals at high risk for certain cancers may prove to be an excellent method for overcoming the barriers that individuals at high risk are facing today. The overall purpose of this manuscript is to provide an overview of screening techniques and to identified barriers and alternate biomarker-based approaches for improvement of endometrial and breast cancer screening in obese women.

Hysteroscopy in postmenopausal bleeding

OBJECTIVES

1) To study the etiology of postmenopausal bleeding (PMB). 2) To study the significance of hysteroscopy in evaluation of the etiopathogenic factors. 3) Correlating the diagnosis after transvaginal sonography (TVS), hysteroscopy and histopathologic diagnosis. 4) Feasibility of conservative management with hysteroscopy in PMB.

DESIGN

Prospective study from January 2008 to June 2009.

SETTING

Department of Obstetrics and Gynecology of Ruby Hall Clinic, Pune.

PATIENTS

Sixty postmenopausal women with complaint of bleeding per vaginum.

INTERVENTIONS

Clinical and sonographic evaluation, followed by diagnostic and/or therapeutic hysteroscopy and guided biopsy. Hysteroscopic images were analyzed and compared with histopathologic results.

MEASUREMENTS AND MAIN RESULTS

On hysteroscopy, endometrium was classified as suggestive of normal, atrophic, endometrial hyperplasia or endometrial carcinoma. Histopathologic diagnosis is taken as a gold standard to determine the efficacy of hysteroscopy in diagnosing endometrial pathologies. The sensitivity and specificity of hysteroscopy in diagnosing endometrial pathologies was assessed.

CONCLUSIONS

In women with PMB, hysteroscopy is the basic tool that allows precise diagnosis of various endouterine pathologies. The average sensitivity of hysteroscopy was 97% in our study and the specificity was 98.66%. Hence, we can conclude that it is highly accurate for evaluating endometrial pathologies. For obvious benign lesions, it also provides treatment in the same sitting, therefore avoiding an extensive, morbid, and expensive procedure like hysterectomy.

Recent trends in Brazilian medical research. An overview

This article reviews 69 original research articles published in 6 Brazilian Medical Journals recently incorporated into the Institute for Scientific Information Journal of Citation Reports, with a view of making them comprehensively available to the readership of CLINICS within a subject category division. We expect this review to increase the visibility of a wide specter of original Brazilian research which may otherwise remain relatively unseen by the interested readership.
