Psychological support is mostly provided through relaxation training, cognitive adjustment practice (CBT) modules, or communication with professionals to reduce emotional stress and improve psychological state (Villinger et al., 2024; Senra et al., 2025). These functions are generally integrated into one application to provide comprehensive services for patients. For instance, some applications offer daily pain management training, psychological education materials and self-assessment tools; Other common functions include medication reminders, self-care suggestions, and forums for patients to communicate with doctors or peers (Azizoddin et al., 2024). The combination of these functions aims to enhance patients' ability of self-management, alleviate the psychological stress brought by cancer and treatment, and improve the quality of life (Shi et al., 2023). 4.2 Clinical evidence Randomized controlled trials and systematic reviews have shown that certain intervention methods can help cancer patients and survivors better alleviate symptoms, adjust their emotions, and improve their quality of life. Research indicates that apps with self-recording and personalized feedback functions can alleviate symptoms such as pain, fatigue and depression. Compared with routine care, such tools usually bring about moderate or significant improvement. For instance, the approach that combines cognitive behavioral therapy with mindfulness practice has been proven to alleviate anxiety and depression. The self-recording function also helps to motivate patients, enable them to deal with discomfort more proactively, and enhance their willingness for self-management (Senra et al., 2025). However, the participation of patients in the app intervention varies. Although many users find these apps easy to use and practical, quite a few give up halfway through. Moreover, as time goes by, the frequency of people using apps generally decreases gradually (Shi et al., 2023). The factors that affect participation include: whether the interface is user-friendly, whether it can be personalized, whether there is a reminder function, and whether there are professionals to help. Evidence shows that intervention methods with professional guidance or regular reminders usually lead to higher patient engagement and more obvious effects. 4.3 Advantages and limitations There are obvious benefits to intervening through an app, such as providing personalized support, simple operation and easy promotion. It can meet the needs of patients at any time, achieve individualized symptom management, and be suitable for the habits and conditions of different people. This approach can also help solve some problems, such as geographical limitations, insufficient medical resources, and patients' fear of others having opinions of them when seeking psychological help. The App can also provide reliable information and timely feedback, which makes it more likely to improve the therapeutic effect (Shi et al., 2023; Azizoddin et al., 2024). Despite the above advantages, this type of intervention still has some shortcomings. The effect largely depends on whether patients can adhere to the use, and this is often difficult to maintain (Senra et al., 2025). Privacy and data security are also issues worthy of attention. Many apps lack complete privacy policies or do not strictly follow data protection norms. In addition, the existing apps vary greatly in terms of quality and scientific basis. Some lack professional review or do not meet the requirements of clinical guidelines. Solving these problems is of great significance for giving full play to the role of apps in cancer treatment and ensuring their safety and reliability. 5 Remote Monitoring Intervention Measures and Their Impacts 5.1 Monitoring indicators: vital signs, activity level, sleep quality Remote monitoring can grasp the health status of patients through multiple indicators, including basic signs such as heart rate, breathing, blood pressure and blood oxygen, as well as activity level and sleep quality. With the help of new technologies such as frequency-modulated continuous wave radar, wearable sensors and Internet of Things devices, data can be continuously collected without contact, and relatively accurate information can be obtained in
