Whilst much is known as to the met and unmet communication needs of prostate cancer patients, few studies have been conducted on the changes in communication between provider and patient over time. Therefore, the aim of our study is to examine (a) whether there are changes over time in the quality of psychosocial care in long-term treatment of localized prostate cancer and (b) whether those changes are associated with the treatment decision.

HAROW is a prospective, observational study designed to collect clinical data and patient reported outcomes (PROs) of different treatment options (hormonal therapy, active surveillance, radiation, operation, watchful waiting) for newly diagnosed patients with localized prostate cancer under real conditions. At 6-month intervals, general clinical data, PROs (e.g. quality of life, quality of physician-patient interaction) and individual costs are documented. We analysed data of N = 1,216 patients at the time of initial diagnosis (T1) and after 6 months (T2).

There is a significant decline in shared decision-making behaviour of physicians for the group of patients undergoing a prostatectomy and for the hormonal therapy group at the time of initial diagnosis and after 6 months. In terms of emotional support by physicians, there is a significant difference between the treatment groups at the time of initial diagnosis with patients undergoing a prostatectomy reporting significantly less support than the hormonal therapy group.

Future research from both, the providers' and the patients' perspective, will have to clarify if we can interpret our results as change in the communication behaviour once the treatment decision for prostatectomy or hormonal therapy is made.
