Personal preferences for avoiding gynecomastia (Stage 1)

Determining INdividual Preferences for Gynecomastia avOidance (DINGO) - Qualitative Stage

Not applicable Interventional St Vincent's Hospital, Sydney · NCT07552922

This project will ask men with prostate cancer and high-risk biochemical recurrence what trade-offs they'd make to avoid breast-related side effects like gynecomastia.

What this trial studies

This qualitative study will use semi-structured interviews with men who have high-risk biochemical recurrence of prostate cancer, including men with and without prior androgen-deprivation therapy (ADT) exposure who have experienced breast-related side effects. Interviews will explore perceptions of gynecomastia and other breast-related harms, their impact on daily life and quality of life, and how patients weigh those harms against cancer control. Responses will be analyzed to define a set of attributes and levels that can be used in a later discrete choice experiment (DCE). Separate ethical approval will be sought for the subsequent DCE that uses the attributes developed here.

Who should consider this trial

Good fit: Men with high-risk biochemical recurrence of prostate cancer who are either yet to receive ADT/ARPI or who have received ADT/ARPI and experienced breast-related side effects are ideal candidates.

Not a fit: Men without high-risk biochemical recurrence, men with unrelated stages of prostate cancer, or those currently receiving psychiatric care related to their cancer would not be suitable and are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the work could lead to better information and decision aids that reflect what men value when choosing treatments that may cause breast-related side effects.

How similar studies have performed: While discrete choice experiments have been used to study trade-offs in cancer treatment broadly, using interviews specifically to develop gynecomastia-focused attributes is a relatively novel approach.
