Symptom trajectories and influencing factors of prostate cancer following radical prostatectomy in chinese patients

Abstract

Background: Patients following radical prostatectomy will encounter various symptoms that may vary depending on the recovery of surgery and the use of adjuvant treatments. However, few studies have used the scale developed for prostate cancer to longitudinally assess the course of symptoms in Chinese patients. This study aimed to identify the symptom trajectories and the influencing factors in the prostate cancer patients of our area. Methods: A prospective observational study was conducted, and 155 patients with prostate cancer from 3 hospitals in Shanghai were recruited. Demographic and disease-related information was collected during the hospitalization. Further information on symptoms, adjuvant treatment, and functional exercise was collected across 4 time points. Growth mixture modeling was used to identify the trajectory patterns of symptoms, and logistic regression was used to determine the predictors. Results: A total of 143 patients completed the investigation of all points, with a lost-to-follow-up rate of 7.7%. Urinary incontinence, urinary tract irritation, sexual dysfunction, pelvic pain, and hormone related symptoms all had group heterogeneity, and the number of latent category trajectories obtained was 4, 3, 3, 4, and 3 respectively. There were differences in demographic, disease, and treatment-related information between the groups. Conclusions: Patients with prostate cancer have different symptom levels across different periods after radical prostatectomy. Medical staff can predict these changes based on the initial level of symptoms and related factors such as age, prostate volume, medical comorbidities, drug of adjuvant treatment to clarify the critical points, populations, and symptoms that require monitoring during follow-up.
