Metastatic breast cancer patients' preferences for exercise programs: a latent class analysis using data from a survey in five European countries.

Purpose: We aimed to identify metastatic breast cancer (MBC) patients' preferences for exercise programs and identify patients' characteristics associated with these preferences, to facilitate implementation of exercise programs for MBC patients.

Methods: We used data from a multinational cross-sectional survey conducted among MBC patients. Patients reported their preferred exercise frequency, intensity, type, session duration, and supervision mode. We used latent class analysis to identify subgroups with similar preferences and descriptive statistics to compare demographic and clinical characteristics of patients within subgroups.

Results: Four distinct classes were identified based on data from 409 participants. Class 1 (47% of participants) is characterized by a preference for moderate exercise with supervision within the health care setting. Most participants in this class had bone metastases. Class 2 (30%) is characterized by a preference for vigorous exercise with supervision. This class included participants who were, on average, younger, and had a higher education level. Class 3 (13%) is characterized by a preference for active walking. These participants were less likely to have bone metastases or comorbidities. Class 4 (10%) is characterized by a preference for recreational walking and included participants who were, on average, older, and less likely to be employed.

Conclusion: We identified four classes of patients with different preferences for exercise programs. Many patients with MBC express exercise preferences that meet the current guideline recommendations. Some patients with MBC may benefit from targeted education to align their preferences and behavior with the amount of exercise that is necessary to gain health benefits.
