Coronary Artery Calcium and Cardiovascular Risk Factors Analysis After RT or Breast Cancer

Overview

This is a no-profit, national, monocenter, retrospective, and prospective low-intervention study. It is a low-intervention study in terms of diagnostic additional procedure (CT scan). It is planned to recruit a maximum of 100 women diagnosed with early-stage breast cancer and treated with adjuvant breast radiotherapy from 2010 to 2017 at the European Institute of Oncology who meet all the inclusion and exclusion criteria. The aim of the Study is to analyze a population of breast cancer patients treated by adjuvant whole breast radiotherapy to identify the most important cardiovascular (CV) risk factors linked to coronary artery disease (CAD) development, in a cure-without-complications oncology strategy.

In the present study a pre-screening activity is planned, that will be conducted by the European Institute of Oncology (IEO) at the Division of Radiotherapy. It will be done to identify and select from the IEO's database about 100 women diagnosed with early-stage breast cancer and treated with adjuvant breast radiotherapy, from 2010 to 2017, and with a \> 5 years clinical Follow up (FU). All patients, who present pre-specified RT treatment, in terms of radiation exposure, and radiation protocol (IORT excluded as well as previous RT treatments), will be proposed to participate in the Study. The researcher of the IEO will contact by phone each identified patient (eligible patients) to request her interest in participating in the present study and to obtain her availability to be contacted by the Investigator of Centro Cardiologico Monzino (CCM) to define all aspects and activities planned in the protocol. Patients who meet all eligibility criteria, after signing the informed consent form, at Centro Cardioogico Monzino, will be enrolled in the study. After execution of the CT scan the patient will be contacted to discuss the CT scan result. In case of high calcium score values, patients will be performing a cardiological medical examination, ECG, and further diagnostic investigations, as clinically indicated.
