The development trajectory of self-advocacy in patients with adjuvant chemotherapy after breast cancer surgery and its predictors.

There is still a lack of research to analyze the development trajectory of the level of self-advocacy and related factors in patients with adjuvant chemotherapy after breast cancer. The present study aims to analyze the development trajectory of self-advocacy and its predictors in patients with adjuvant chemotherapy after breast cancer. A total of 242 breast cancer patients admitted to our hospital from January 2024 to December 2024 were collected. A total of 200 patients participated in 4 follow-up surveys before chemotherapy (T1), early chemotherapy (T2), mid-chemotherapy (T3), and late chemotherapy (T4), with a valid questionnaire recovery rate of 82.64%. Latent class growth analysis was used to analyze the development trajectory of self-advocacy in patients with postoperative adjuvant chemotherapy for breast cancer, and the influencing factors' development trajectory of self-advocacy level was analyzed by binary logistic regression. The self-advocacy scores of breast cancer patients with adjuvant chemotherapy after surgery at T1 to T4 were (56.49 ± 13.89), (56.69 ± 14.50), (57.15 ± 16.89), and (56.59 ± 19.96) points, respectively. The scores of self-advocacy at the 4 time points were positively correlated (P < .05), which met the premise of model fitting. The development trajectory of self-advocacy of patients with adjuvant chemotherapy after breast cancer surgery was plotted, and the patients were divided into high self-advocacy group (n = 85) and low self-advocacy group (n = 115) according to the development trajectory. Multivariate logistic regression analysis showed that breast-conserving surgery, education, Consumer Experiences of Stigma Questionnaire score, and Nurse Patient Trust Scale score were the influencing factors of the development trajectory of self-advocacy in patients with adjuvant chemotherapy after breast cancer surgery (P < .05). Breast-conserving surgery, education, Consumer Experiences of Stigma Questionnaire score, and Nurse Patient Trust Scale score were the influencing factors of the development trajectory of self-advocacy in patients with adjuvant chemotherapy after breast cancer surgery.
