The incidence rates of endometrial hyperplasia and endometrial cancer: a four-year population-based study.

ABSTRACT: INTRODUCTION:The aim of this study was to determine the incidence rates of endometrial hyperplasia (EH) and endometrial cancer (EC) in the Republic of Korea using national insurance claim data generated from 2009 to 2012. MATERIALS AND METHODS:Data that were generated from 2009 to 2012 were sourced from the Korean Health Insurance Review and Assessment Service-National Inpatients Sample database. The data from women who were assigned diagnosis codes representing EH or EC within 1 month of being assigned codes that corresponded to procedures that included endometrial biopsies and several types of gynecologic surgeries to obtain endometrial pathology samples, were selected for analysis. RESULTS:Data from 2,477,424 women were entered into the database between 2009 and 2012, and the data from 1,868 women with EH and 868 women with EC were extracted for analysis. The mean ages of the patients were 44.1 ± 0.4 years for those with EH and 52.7 ± 0.6 years for those with EC. The EH and EC incidence rates were 37 per 100,000 woman-years and 8 per 100,000 woman-years, respectively. The EH and EC incidence rates peaked when the women were in their late forties and fifties, respectively. CONCLUSIONS:The EH and EC incidence rates determined in this study were somewhat lower than those determined from previous studies. Further studies are required that adjust the data for race, menopausal hormone therapy, and obesity.

Project description:Abnormal uterine bleeding (AUB) represents a common diagnostic challenge, as it might be related to both benign and malignant conditions. Endometrial cancer may not be detected with blind uterine cavity sampling by dilatation and curettage or suction devices. Several scoring systems using different ultrasound image characteristics were recently proposed to estimate the risk of endometrial cancer (EC) in women with AUB. The aim of the present study was to externally validate the predictive value of the recently proposed scoring systems including the Risk of Endometrial Cancer scoring model (REC) for EC risk stratification. It was a retrospective cohort study of women with postmenopausal bleeding. From June 2012 to June 2020 we studied a group of 394 women who underwent standard transvaginal ultrasound examination followed by power Doppler intrauterine vascularity assessment. Selected ultrasound features of endometrial lesions were assessed in each patient. The median age was 60.3 years (range ± 10.7). The median body mass index (BMI) was 30.4 (range ± 6.0). Histological examination revealed 158 cases of endometrial hyperplasia (EH) and 236 cases of EC. Of the studied ultrasound endometrial features, the highest areas under the curve (AUCs) were found for endometrial thickness (ET) (AUC = 0.76; 95% CI: 0.71-0.81) and for interrupted endomyometrial junction (AUC = 0.70, 95% CI: 0.65-0.75). Selected scoring systems presented moderate to good predictive performance in differentiating EC and EH. The highest AUC was found for REC model (AUC = 0.75, 95% CI: 0.70-0.79) and for the basic model that included ET, Doppler score and interrupted endometrial junction (AUC = 0.77, 95% CI: 0.73-0.82). REC model was more accurate than other scoring systems and selected single features for differentiating benign hyperplasia from EC at early stages, regardless of menopausal status. New scoring systems, including the REC model may be used in women with AUB for more efficient differentiation between benign and malignant conditions.

Project description:BackgroundThere are limited data on the incidence of cardiovascular disease among cancer patients in the pre-tyrosine kinase inhibitor (TKI) era. Such data are important in order to contextualize the incidence of various cardiovascular outcomes among cancer patients enrolled in clinical trials of new agents and for postmarketing surveillance.MethodsA retrospective cohort study was conducted using data from the Kaiser Permanente Northern California (KPNC) population of cancer patients. The inclusion criterion was a KPNC Cancer Registry diagnosis of any of several selected solid and hematologic tumors between 1997 and 2009 not treated with a TKI. Endpoints were identified using ICD-9 codes and included acute coronary syndrome, heart failure, stroke, cardiac arrest, hypertension, venous thromboembolism, all-cause mortality, and cardiovascular mortality. Event rates were calculated according to type of cancer and number of cardiovascular risk factors.ResultsThe study included almost 165 000 individuals with a broad variety of tumor types. The parent cohort was 54% female and 35% were ≥70 years old. Cardiovascular risk factors such as diabetes mellitus (14% of patients with solid tumors, 15% of patients with liquid tumors), dyslipidemia (33%, 31%), hypertension (50%, 49%), and smoking (35%, 32%) were common. The most frequent adverse outcomes were incident hypertension (26.8-61.0 cases per 1000 person-years, depending on the type of cancer), heart failure (9.4-78.7), and acute coronary syndrome (2.6-48.1). These event rates are high compared to what has been reported in prior KPNC cohort studies of patients without cancer. The rates of acute coronary syndrome, heart failure, and ischemic stroke increased with increasing numbers of cardiovascular risk factors.ConclusionsIn a population of patients with cancer not exposed to TKIs, cardiovascular risk factors and outcomes are very common, regardless of cancer type. These data can inform the evaluation of potential excess cardiovascular risks from new interventions.
