Medical biosensors have set the basis of medical diagnostics, and Artificial Intelligence (AI) has boosted diagnostics to a great extent. However, false results are evident in every method, so it is crucial to identify the reasons behind a possible false result in order to control its occurrence. This is the first critical state-of-the-art review article to discuss all the commonly used biosensor types and the reasons that can give rise to potential false results. Furthermore, AI is discussed in parallel with biosensors and their misdiagnoses, and again some reasons for possible false results are discussed. Finally, an expert opinion with further future perspectives is presented based on general expert insights, in order for some false diagnostic results of biosensors and AI biosensors to be surpassed.

This narrative review explores the interconnected relationship between quality of life (QoL) and satisfaction with nursing care (SNC) among cancer patients, recognizing that cancer’s burden extends beyond survival and significantly affects physical, psychological, and social well-being. A non-systematic search of PubMed, CINAHL, Scopus, and Google Scholar (2000–2025) identified relevant literature using keywords related to oncology nursing, QoL, SNC and patient satisfaction. Inclusion criteria encompassed peer-reviewed studies (quantitative, qualitative, and reviews) involving adult cancer populations and validated assessment instruments. Pediatric and non-nursing studies were excluded. Both QoL and SNC are critical outcomes in cancer care. QoL is an individual’s subjective perception and SNC reflects the patient’s subjective evaluation of how well nursing services align with their expectations, encompassing empathy, competence, and responsiveness. Research consistently demonstrates a strong positive association between high SNC and superior QoL outcomes, particularly through effective pain and symptom management, reducing psychological distress, and fostering patient empowerment. This relationship, however, is moderated by factors such as the patient’s disease stage, the type of care (hospital vs. palliative/home care), and organizational deficits like high nurse workload, which can undermine the delivery of high-quality care. Ultimately, ethical nursing practices are crucial for translating professional duty into positive patient experiences that are favorably linked with both SNC and QoL outcomes for cancer patients.
