Lung cancer is one of the most common malignancies. End stage of lung cancer The patient is suffering from the pain caused by the disease, dyspnea and other pain, at the same time To be affected by loneliness, anxiety, fear and other emotional interference, seriously affect the mental health And quality of life. Compared with 1999, the life years of lung cancer standardized disability loss, early death loss and disability adjustment life have increased significantly in 2019, and it is expected that the incidence and disease burden will become more severe in the future [1] . Lung cancer patients progress to the terminal stage, when it is impossible to use medical surgery to effectively cure the tumor. Under the influence of factors such as incurable diseases, short life cycle and clinical symptoms, lung cancer patients are easy to breed negative psychology such as loneliness and fear. Continuous negative psychology can kill the will to survive and reduce treatment compliance and quality of life [2] . Routine nursing methods can meet the needs of patients’ physiological dimension, but the psychological dimension of patients and nursing efforts are insufficient. Life reviews can allow patients to gain a sense of accomplishment and satisfaction in recalling the past, thus alleviating negative emotions [3] . Watson Humanistic care theory is a kind of humanistic care nursing mode, which can be based on patients The actual condition, to provide individualized, targeted nursing services. Watson Care theory pays attention to humanistic care, emphasizing that nursing staff should provide a comprehensive perspective, combined with the individual characteristics of patients, targeted psychological support, to improve the psychological state of patients [4] . The study points out that the combination of life review and Watson care theory has a value in improving the physical and mental burden of lung cancer patients [5] . In view of the few reports on the application of this joint measure in patients with terminal lung cancer, 72 patients with terminal lung cancer admitted to our hospital from March 2021 to January 2024 were selected for verification and discussion.

The end stage of lung cancer is the end stage of lung cancer. The clinical treatment at this stage is mainly palliative therapy and hospice care, and the treatment focuses on improvement rather than cure. How to reduce the symptom burden of patients, improve the quality of life, reduce the regret of life dying, is the main point of clinical nursing intervention. The survey shows that patients with terminal lung cancer can reduce the quality of life under the influence of symptom burden and negative emotions, which will form a vicious circle, which can affect the survival cycle [7] . Routine care countermeasures are not effective for patients at this stage. Watson Care theory is one of the research hotspots of cancer clinical care in recent years [8] . This theory belongs to a theory of humanistic care, which emphasizes that providing nursing intervention for patients should take into account both physiological and psychological dimensions, and formulate individual physical and mental care strategies for them from the perspective of humanistic care [8] . This study concluded that the SAS and SDS scores were lower in the study group. It shows that the combination therapy in this study can be effective in reducing psychological stress in patients. The analysis reason is that by guiding patients to recall the past, the life review can distract the attention to the current situation in the immersive memory, and in the course of life reorganization, re-recognize and affirm themselves, which is conducive to alleviating their negative psychology such as inferiority and fear [9] . Provide patients with Watson care theory, this study attaches great importance to the individual differences of patients, respect the individual ideas, to provide physical and psychological dimensions of comfort for nursing goal, through education and psychological counseling, pain and complications intervention eliminate adverse factors affecting the state of body and mind, let it to comfortable, pleasant attitude in the face of life and treatment [10] . Life review combined with Watson care theory, can help patients to relieve negative emotions, enhance the psychological efficacy of patients, and let them face treatment and death with a natural attitude. The higher QOL scores in the study group indicated that the combined measures could improve QOL. Guo Wei [11] Reported that the combination of life review and Watson care theory can significantly improve the quality of life of lung cancer patients. Consistent with the conclusions of this study. The life review intervention affirms the patient’s life experience, so that they can re-recognize their own existence value, conducive to reduce the negative impact of pain. Watson Care theory pays attention to the comprehensiveness of nursing, from the correction of patients’ mistakes and eliminates the adverse factors that are not conducive to their treatment and life, combined with careful and comprehensive life and psychological nursing, help to reduce the psychological pressure of patients, improve the quality of life [12] . In addition, this study believes that the combination of life review and Watson care theory, by reshaping the meaning of life for patients and positive self-affirmation, is conducive to improving the coordination degree of medical work, ensure the implementation of medical intervention in place, and also help improve the quality of life.

In conclusion, the life review combined with Watson care theory was applied to lung cancer in the clinical care of end-stage patients, it can improve their psychological condition and improve the quality of life Quantity, reduce the pain, and enhance the sense of self-esteem.
