###### Abstract  
The purpose of the study was to design, develop, and implement an e-oncology: a technical solution based on self-management supportive treatment using a mobile communication device utilizing NFC technology. The goal was to optimize the process of treating oncology patients and make it more efficient. The idea of the designed system was to create a complex multifunctional mobile application that would help in their treatment and subsequently make the work of the medical staff easier. Direct attention was paid to the design and implementation of the NFC module itself, including the development and debugging of the mobile application, which was created for devices with the Android operating system. The developed system was successfully tested at a clinical- and radiation-oncology workplace for 60 days before implementation. In total, two oncology clinics and 100 patients were included in the testing process. Based on the relevant feedback, it can be concluded that the proposed system significantly shortened the waiting times for patients in the process of their oncology treatment and brought significant benefits in terms of more efficient use of the time of doctors, nurses, and especially patients. near-field communication; android operating system; self-management therapy; electronic oncologic ambulance +

self-management supportive treatment is to maintain health and acceptable well-being, which leads to the extension and maintenance of an adequate quality of life. Thanks to the experience gained at various clinics of the Zilina Hospital and the AMETYST+ oncology centre in Zilina, we actively deal with the issue of therapy self-management. A substantial amount of the required input data for implementing this approach is primarily obtained based on interviews with oncology patients whose treatment in the mentioned facilities has been ongoing for several years. Based on such experience and information, a different view of treating the problem is taken. A technical solution from an oncology patient's point of view is made, namely, to help patients orientate themselves in the process of treatment self-management. This process alerts patients to problems they are experiencing but may not be attributed to complex oncology treatment. Due to the broad expansion of mobile devices, a mobile application has been designed and developed that allows patients to record symptoms affecting their treatment and lifestyle and places the patient in a queue when they arrive at the clinic. This work aimed to create a complex system using NFC and mobile technologies foremost for the Android OS (which is widely used by the clients), for recording the treatment of oncology patients and the electronification of oncology clinics. To achieve this goal, it was necessary to focus on defining the principles of treatment of cancer patients and the side-effects caused by cancer treatment. The focus was on identifying self-directed treatment, which was the main motivation for creating a mobile application. The treatment process of oncology patients begins with the identification of the disease and continues with the setting of chemotherapy, radiotherapy, and other types of available treatment techniques. The treatment is mainly carried out in the Department of Clinical and Radiation Oncology. Caring for oncology patients does not end in the hospital, as it is necessary for patients to actively approach treatment and thus try to improve their health status, for instance, by monitoring subjective feelings and symptoms of the disease. The design and implementation of the described solution were based on the conclusions of medical councils, practical aspects of the medical environment, and, especially, the currently occurring problems in both the clinical and outpatient sectors. Currently, NFC technology is quite often used, but its direct implementation in connection with the application part for the patient is solved only on a theoretical level.
