Molecular and Epidemiological Characteristics of Endometrial Cancer in Brazil

Study Overview
=================
Brief Summary
-----------------
An evaluation of the molecular and epidemiological aspects of endometrial cancer in Brazil is necessary to understand the high frequency of advanced disease. A better understanding of the current situation will generate essential data for the future development of national or international cooperative programs that aim to improve outcomes in these patients and generate additional knowledge for much-needed clinical trials in this population.

Detailed Description
-----------------
This is a retrospective observational cohort study. In this study, we will include patients diagnosed with endometrium cancer from January 2016 to December 2019 in participating sites and collect data on demographics, clinicopathological characteristics, treatment patterns, and outcomes. Data will be collected from medical records in selected centers that comprise different regions of Brazil. The patient data sources will be the medical records of the patients. Patients will continue to receive treatment and clinical evaluations for endometrial cancer according to what is determined by their medical team, according to the usual standards of treatment and clinical practice of each center. To minimize patient selection bias, physicians should invite all consecutive eligible patients. This study also provides for the collection and archiving of tumor tissue material. The samples will be tested to characterize the molecular subtype of endometrial cancer and will be sequentially stored in a biorepository to enable future translational studies, according to national regulations.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Epidemiological Characteristics of the Brazilian Population with Endometrial Cancer | This measure encompasses key epidemiological factors of the Brazilian population diagnosed with endometrial cancer, including age distribution, racial and ethnic demographics, geographic regions, and relevant comorbidities. These details will provide insights into the demographic makeup of the study population. | At the time of diagnosis. | 
| Molecular Profile Analysis of Endometrial Cancer Cases | This measure focuses on analyzing the molecular profile of endometrial cancer cases in the Brazilian population. It includes information about specific genetic mutations, biomarkers, and molecular subtypes that are relevant to endometrial cancer. Understanding the molecular landscape can contribute to insights into disease progression and potential targeted therapies. | Throughout the study period, an average of 36 month. | 
| Treatment Patterns for Endometrial Cancer in Brazil | This measure examines the treatment patterns employed for endometrial cancer within the Brazilian population. It includes details about types of treatments received, such as surgery, chemotherapy, radiation therapy, and hormonal therapy. Additionally, it explores the utilization of targeted therapies or immunotherapies. | From diagnosis to completion of treatment, between January 2016 and December 2019. | 
| Endometrial Cancer Outcomes in the Brazilian Population | This measure assesses the outcomes of endometrial cancer cases in the Brazilian population. It includes survival rates, disease recurrence rates, response to treatment, and overall disease progression. By evaluating these outcomes, a comprehensive understanding of the disease's impact on the population can be achieved. | From diagnosis to the end of the study follow-up period, an average of 36 months. |
