Abstract: Objective: To determine the current status of treatment decision-making dilemma in patients with breast cancer- related lymphedema, so as to provide reference for the implementation of decision support for medical staffs. Methods: Quantitative and qualitative mixed research methods were adopted. In the quantitative study, purposive sampling method was used and 190 patients with breast cancer-related lymphedema were included from May 2021 to May 2022 in a Class A tertiary cancer hospital in Tianjin. Through purposive sampling and maximum difference sampling, patients with decision- making dilemma in the questionnaire survey were selected for qualitative interview. Results: A total of 187 valid questionnaires(98.42%) were collected, and the score of decision-making dilemma was 26.56(16.06, 38.28 ） points. Among them, 45 patients(24.1%) had a score of more than 37.5 points, indicating decision-making delay, and 102 patients(54.5%) had a score of more than 25 points, indicating decision-making dilemma. Qualitative research extracted four themes, which were insufficient knowledge of breast cancer related lymphedema and treatment, lack of professional decision-making information, the impact of negative emotions, and lack of support system. Conclusion: Patients with breast cancer-related lymphedema generally have treatment decision-making difficulties. Medical staffs should pay attention to health education and psychological support of patients, and give appropriate interventions.
