Detection rates and factors affecting thereof in endometrial hyperplasia, endometrial carcinoma, and cervical glandular lesions on cervical smear. Cancer Med 2023; 12:17581-17591. [PMID: 37501510 PMCID: PMC10523982 DOI: 10.1002/cam4.6376] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 07/08/2023] [Accepted: 07/14/2023] [Indexed: 07/29/2023] Open
Abstract
INTRODUCTION Endometrial lesions are morphologically diverse and uncommon on cervical smears, with its detection rate and associated diagnostic categories uncharacterized. In this study, cervical smears matched to histologically proven endometrial hyperplasias and carcinomas were reviewed and compared with cervical in-situ-carcinomas/carcinomas, aiming to detail the diagnostic performance of cervical smears for upper tract and glandular lesions. METHODS Pathology reports of cervical smears, hysterectomies, endometrial and cervical biopsies from 1995 to 2021 were retrieved. Diagnoses of cervical smears were matched to endometrial hyperplasias and carcinomas, or cervical carcinomas and reviewed. RESULTS Totally 832 cervical smears (272 cervical carcinomas, 312 endometrial carcinomas, and 248 hyperplasias) were included. Considering all cytologic glandular diagnosis as positive, the detection rate of cervical adenocarcinoma-in-situ was the highest (64.3%), followed by cervical adenocarcinoma (63.8%), endometrial carcinoma (31.7%), and hyperplasia (with atypia-8.5%; without atypia-2.3%) (p < 0.001). Endometrial hyperplasia was most often diagnosed as atypical squamous cells of undetermined significance (ASCUS) (5.0%) or atypical glandular cells, not otherwise specified (3.6%) without indication of endometrial origin. For endometrial carcinomas, higher FIGO grading and endocervical involvement were associated with higher detection rates across all diagnostic categories (p = 0.002-0.028). High FIGO grade was associated with suspicious/favor neoplastic (C4) (31.1%vs10.3%, p < 0.001) and carcinoma (C5) (17.8% vs. 5.6%, p = 0.005) categories, but not for all glandular diagnoses combined (33.3% vs. 31.0%, p = 0.761). CONCLUSION Detection rates for endometrial lesions are lower than cervical lesions but not insignificant. Endometrial hyperplasia should be recognized as a differential of human papilloma virus-negative ASCUS and prompt consideration of investigation of the upper genital tract.

Abstract
Objectives: The objectives of this study were (1) to estimate the frequency of preoperative abnormal cervical cytology (CC), (2) to explore correlations between preoperative CC and specific clinicopathological prognostic factors (tumor stage, endometrioid grade, myometrial invasion, lymphovascular space involvement, cervical involvement, and recurrence), and (3) to examine the impact of preoperative CC on disease-free survival (DFS) and overall survival (OS) in Saudi patients with endometrioid-type endometrial cancer (EC). Materials and Methods: A retrospective cross-sectional study was conducted at a tertiary hospital in Saudi Arabia. The study’s inclusion criteria included: (1) patients who underwent staging operation for EC from 2010–2014, (2) patients who had preoperative CC results within 3 months before staging operation, and (3) patients with final histopathological diagnosis of endometrioid-type EC. Results: Hundred and sixteen patients (n = 116) met the study’s inclusion criteria. CC results were abnormal in 46 patients (39.7%). Patients with abnormal CC had statistically significant higher rates of unfavorable Grades II–III tumor and cervical involvement than patients with normal CC (P = 0.004, chi-square test). There were no statistically significant differences (log-rank test) between patients with normal and abnormal CC with regard to DFS (P = 0.525) and OS (P = 0.166). Multivariate analyses of DFS and OS (Cox proportional hazards model) failed to show preoperative CC as a significant independent prognostic factor of DFS and OS (P > 0.05). Conclusion: The frequency of abnormal preoperative CC in patients with endometrioid-type EC is not uncommon. Abnormal CC correlates with poor prognostic factors, namely high tumor grade and cervical involvement. Preoperative CC is not a significant independent prognostic factor of survival.

Sensitivity of cervico-vaginal cytology in endometrial carcinoma: A systematic review and meta-analysis. Cancer Cytopathol 2020; 128:792-802. [PMID: 32202704 DOI: 10.1002/cncy.22266] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Revised: 02/27/2020] [Accepted: 03/02/2020] [Indexed: 12/24/2022]
Abstract
Cervico-vaginal cytology is primarily a cervical cancer screening test. The anatomical continuity of the uterine cavity with the cervix makes the Papanicolaou (Pap) test accessible to evaluate signs of disease shed from the endometrium. Our aim was to determine the sensitivity of routine Pap test in endometrial carcinoma detection and its relationship with clinico-pathologic factors. We performed a systematic review of studies reporting Pap test results prior to diagnosis of or surgery for endometrial carcinoma between 1990 and 2018 in PubMed or Web of Science. Two independent reviewers extracted data and assessed study quality using an adapted Newcastle-Ottawa Quality Assessment Scale and Quality Assessment of Diagnostic Accuracy Studies tool. We identified 45 studies including a total of 6599 women with endometrial cancer. Abnormal Pap test results prior to diagnosis of or surgery for endometrial carcinoma were observed in 45% (95% CI, 40%-50%) of study participants. This percentage was significantly higher among those of non-endometrioid histology compared with endometrioid subtypes (77% [95% CI, 66%-87%] vs 44% [95% CI, 34%-53%], respectively; P heterogeneity <.001). Several clinico-pathologic factors were related to a higher percentage of abnormal Pap test results, including high-stage, myometrial invasion >50%, high histological grade, positive peritoneal cytology, presence of lymph node metastasis, cervical involvement, and lymphovascular invasion (P heterogeneity <.05 for all variables). Routine cervical cytology can detect endometrial cancer in almost half of patients, whereas sensitivity is higher among individuals with non-endometrioid histology or more advanced cancers. This review summarizes the current clinical and prognostic value of cervical cytology in endometrial carcinoma. Recent technological developments using molecular biomarkers may improve accuracy for early cancer detection.

Diagnostic Accuracy of Clinical Biomarkers for Preoperative Prediction of Lymph Node Metastasis in Endometrial Carcinoma: A Systematic Review and Meta-Analysis. Oncologist 2019; 24:e880-e890. [PMID: 31186375 DOI: 10.1634/theoncologist.2019-0117] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2019] [Revised: 04/29/2019] [Accepted: 05/01/2019] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND In endometrial carcinoma (EC), preoperative classification is based on histopathological criteria, with only moderate diagnostic performance for the risk of lymph node metastasis (LNM). So far, existing molecular classification systems have not been evaluated for prediction of LNM. Optimized use of clinical biomarkers as recommended by international guidelines might be a first step to improve tailored treatment, awaiting future molecular biomarkers. AIM To determine the diagnostic accuracy of preoperative clinical biomarkers for the prediction of LNM in endometrial cancer. METHODS A systematic review was performed according to the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. Studies identified in MEDLINE and EMBASE were selected by two independent reviewers. Included biomarkers were based on recommended guidelines (cancer antigen 125 [Ca-125], lymphadenopathy on magnetic resonance imaging, computed tomography, and 18F-fluorodeoxyglucose positron emission tomography/computed tomography [18FDG PET-CT]) or obtained by physical examination (body mass index, cervical cytology, blood cell counts). Pooled sensitivity, specificity, area under the curve (AUC), and likelihood ratios were calculated with bivariate random-effects meta-analysis. Likelihood ratios were classified into small (0.5-1.0 or 1-2.0), moderate (0.2-0.5 or 2.0-5.0) or large (0.1-0.2 or ≥ 5.0) impact. RESULTS Eighty-three studies, comprising 18,205 patients, were included. Elevated Ca-125 and thrombocytosis were associated with a moderate increase in risk of LNM; lymphadenopathy on imaging with a large increase. Normal Ca-125, cytology, and no lymphadenopathy on 18FDG PET-CT were associated with a moderate decrease. AUCs were above 0.75 for these biomarkers. Other biomarkers had an AUC <0.75 and incurred only small impact. CONCLUSION Ca-125, thrombocytosis, and imaging had a large and moderate impact on risk of LNM and could improve preoperative risk stratification. IMPLICATIONS FOR PRACTICE Routine lymphadenectomy in clinical early-stage endometrial carcinoma does not improve outcome and is associated with 15%-20% surgery-related morbidity, underlining the need for improved preoperative risk stratification. New molecular classification systems are emerging but have not yet been evaluated for the prediction of lymph node metastasis. This article provides a robust overview of diagnostic performance of all clinical biomarkers recommended by international guidelines. Based on these, at least measurement of cancer antigen 125 serum level, assessment of thrombocytosis, and imaging focused on lymphadenopathy should complement current preoperative risk stratification in order to better stratify these patients by risk.

Abstract
INTRODUCTION Abnormal cervical cytology in patients with endometrial cancer (EC) has been associated with poor outcome. The aim of this study was to evaluate whether cervical cytology could contribute to an improved preoperative identification of high-grade EC (serous, clear cell, carcinosarcoma, high-grade endometrioid EC) in final histology. METHODS A retrospective cohort study was performed in five hospitals in the Netherlands. A total of 554 patients with EC that underwent primary surgical treatment between 2002 and 2010 were included. Primary outcome was defined as the contribution of abnormal cervical cytology in the preoperative identification of high-grade EC. As secondary outcome, recurrence-free survival (RFS) and disease-specific survival were determined based on preoperative cervical cytology, and compared to the currently established risk factors: myometrial invasion, high-grade and lymph vascular space invasion. RESULTS Abnormal cervical cytology was present in 45.1%. For patients with preoperative inconclusive and high-grade histology, the presence of abnormal cervical cytology contributed to an improved identification of high-grade EC in final histology (odds ratio [OR] 6.40 [95% confidence interval {CI}: 1.92-21.26]; OR 2.86 [95% CI: 1.14-7.14]), respectively. Patients with abnormal cervical cytology had a significant worse 5-year median RFS. Abnormal cervical cytology was independently related to RFS (hazard ratio 1.67 [95% CI: 1.04-2.68]) and disease-specific survival (hazard ratio 3.15 [95% CI: 1.74-5.71]). CONCLUSIONS Abnormal cytology contributes to the preoperative identification of patients with high-grade EC, and is associated with compromised outcome. Future studies are warranted to determine whether cervical cytology could be incorporated into preoperative prediction models for lymph node metastasis.

Abstract
In the Western world, endometrial carcinoma is the most common malignant tumour of the female genital tract and is the fourth most common cancer in women. Two different clinicopathological subtypes are recognised: the oestrogen-related (type I, endometrioid) and the non-oestrogen related (type II, non-endometrioid). This article reviews the epidemiology, risk factors, genetic alterations during endometrial carcinogenesis, features of tumours and precursors and early detection of the disease. Insights into the epigenetic alterations, with emphasis on DNA methylation during endometrial carcinogenesis, and their diagnostic value are also provided.

Abstract
BACKGROUND In addition to the reporting of atypical glandular cells (AGC) and adenocarcinoma (ADCA), the 2001 Bethesda System requires the reporting of benign-appearing endometrial cells in women aged >40 years (BAEMC). In this study, the authors evaluated the contribution of each of these reporting categories to the sensitivity and specificity of a liquid-based Papanicolaou test for endometrial carcinoma or hyperplasia. METHODS Over the 3-year study period, in the setting of a large, multihospital health care system, the authors analyzed the results from liquid-based Papanicolaou tests that were performed within the 6 months that preceded a histologic diagnosis of endometrial carcinoma or hyperplasia and that were reported according to the 2001 Bethesda System. RESULTS Two hundred seventy-two women had a histologic diagnosis of endometrial hyperplasia (n = 199) or malignancy (n = 73) within 6 months after a Papanicolaou test. In total, 188,594 Papanicolaou tests (91,385 from women aged >40 years) were interpreted during the study period and resulted in 3810 diagnoses of BAEMC, 326 diagnoses of AGC, and 30 diagnoses of ADCA. Only 28 of 73 women (38.4%) with endometrial carcinoma had cytologically AGC or ADCA reported on a previous Papanicolaou test. The reporting of BAEMC increased this sensitivity by only 5.5% (4 additional tests) but decreased the specificity of the Papanicolaou test for endometrial malignancy from 99.8% to 96%. For endometrial hyperplasias, the sensitivity of the Papanicolaou test was even lower (39 of 198 tests; 19.7%), but BAEMC represented the majority of endometrial-type cells reported (36 of 39 tests). CONCLUSIONS The reporting of BAEMC led to an only marginal increase in sensitivity that had to be weighed against the significant loss in specificity of the Papanicolaou test for endometrial neoplasia.
