Radiation Therapy of Patients with Squamous Cell Cancer of the Esophagus with an Electronic Device Implanted in the Heart. Cases Reports

Every year, about a million electronic devices implanted in the heart are installed worldwide. In the Russian Federation, there are no accurate statistics on pacemakers. Modern pacemakers (pacers) are characterized by their small size, high sensitivity and susceptibility to ionizing radiation (IR), which increases the risk of temporary or irreversible damage to the device. Throughout the world, the number of cancer patients with electronic devices implanted in the heart has increased over the past decade. Despite the development of modern methods of radiation therapy (RT), this method has a certain risk of complications for cancer patients with ECS. We currently use the 2020 update of the JASTRO/JCS guidelines for RT in patients with cardiac implantable devices to guide management of patients with pacemakers. Similar recommendations have not yet been developed in the Russian Federation, as in many other countries, which makes this problem especially relevant. This article demonstrates a multidisciplinary team approach to the management and treatment of patients with esophageal squamous cell carcinoma (ESCC) with an implantable pacemaker.
