The Compatibility of Preoperative Endometrial Biopsies With Postoperative Final Pathology in Endometrial Cancer

June 1, 2021 updated by: Erhan Okuyan,M.D, Batman Training and Research Hospital

The Compatibility of Preoperative Endometrial Biopsies With Postoperative Final Pathology in Endometrial Cancer; Should Preoperative Pathology Samples of Patients Referred to a Tertiary Center be Re-evaluated?

Although there are many studies comparing preoperative and postoperative histological diagnoses in the literature, there are no studies evaluating the compatibility of preoperative histological diagnoses obtained from different centers with postoperative histological diagnoses.Therefore, in our study, we aimed to determine whether preoperative pathological specimens need to be re-evaluated in the referenced hospitals by comparing the compatibility of endometrial specimens in secondary care and tertiary centers with their final pathologies.In our study, we aimed to reveal the under and overdiagnosis rates of the preoperative histological diagnoses of our hospitals compared to the final pathology.

Detailed Description

Medical data of 960 patients diagnosed with endometrial cancer by endometrial biopsy between 2002 and 2016 were retrospectively analyzed. Of these patients, 41 were excluded from the study due to non-surgical treatment, 254 patients having biopsy only in one center preoperatively, and lack of medical data in 52 patients.The study included 613 patients who had preoperative endometrial biopsy specimens evaluated by two different centers, diagnosed with endometrial cancer and treated surgically. Our study was conducted in the gynecological oncology department of our university after obtaining the approval of the ethics committee numbered 430-2019.The clinicopathological characteristics of the patients were evaluated by examining the hospital records of age, gravida, parity, BM (body mass index), menopausal status and systemic diseases. Histopathological and clinical features of endometrial cancer were reviewed.In this study, endometrial biopsy samples taken in the second stage state hospital were re-evaluated by the gynecopathologist working at the university hospital and / or the evaluation process was carried out in two steps by examining the repeated endometrial biopsy sampling.Patients diagnosed with endometrial cancer were treated surgically in our clinic. Endometrial sampling results based on uterine cancer risk groups; While histologically endometrioid and nonendometrioid were evaluated in two groups, the greade1-2 (low risk), greade3 (high risk) of uterine cancer were evaluated in four groups as those without malingnancy (benign and premaling lesions).By comparing these preoperative histological diagnoses with postoperative surgical final pathology, the accuracy rates for histological type and greade were determined. In addition, lower diagnosis, comorbidity and higher diagnosis rates compared to final pathology were examined for two different centers.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Probability Sample

Study Population

Patients who received treatment in a tertiary care center for cancer of endometry

Description

Inclusion Criteria:

  • Female patients aged 40-90 years diagnosed with endometrial cancer according to

endometrial sampling results

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Comparison of endometrial sampling results performed in 2 different centers
Time Frame: 1 year

1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
To reveal the rates of under and overdiagnosis of preoperative histological results
Time Frame: 1 year
Correlation of preoperative pathological diagnoses with postoperative final pathological diagnoses.
