BACKGROUND Myocardial fibrosis is a well-known side effect of radiotherapy. Fragmented QRS (fQRS) has been shown to be a marker of myocardial fibrosis. We postulated that radiotherapy induces development of fQRS in breast cancer patients. PATIENTS AND METHODS Breast cancer patients receiving locoregional radiotherapy were enrolled. Patients who had fQRS on electrocardiography (ECG) before rad...

Recently, the linear-quadratic equation has been used to construct the dose-response relationships of ionizing radiation. The radiobiological theory on which this relationship is based indicates that at low doses, the risk of a biological lesion being formed should depend linearly on dose if a single event is required or quadratically on dose if two events are required. The same approach has al...

conclusions comprehensive protection programs with on-the-job training courses for staff members are strongly recommended, as well as, the provision of radiological shields and gonad shielding protocols in radiology departments to reduce the patient’s radiation dose during radiological examinations. materials and methods a retrospective, observational cross-sectional study on the application of...

Thymic carcinomas are rare aggressive cancers with limited clinical trial data. Its usual treatment is surgical resection with variable response to chemotherapy and radiation. It usually presents as anterior mediastinal mass with late sequela of metastases to the lymph nodes, pleura and bones. We present of thymic carcinoma with a rare initial presentation of vertebral metastases causing spinal...
