Qualitative and Quantitative Assessment of Patient and Carer Experience of Chemotherapy (Docetaxel) in Combination with Androgen Deprivation Therapy (ADT) for the Treatment of Metastatic Hormone-Sensitive Prostate Cancer (mHSPC).

INTRODUCTION: Recent studies suggest that docetaxel plus androgen deprivation therapy can prolong survival among men with metastatic hormone-sensitive prostate cancer (mHSPC). However, as a cytotoxic therapy, there is a need to understand the experiences of men with mHSPC receiving docetaxel and their carers in a real-world setting. METHODS: During phase 1, semi-structured qualitative interviews were conducted with men with mHSPC (n = 31) and their carers (n = 14) in Europe to elicit in-depth data concerning their experiences with docetaxel. Eighteen men were also asked to record their experiences in a diary for 7 days. During phase 2, men with mHSPC (n = 161) and carers of men with mHSPC (n = 135) completed an online survey comprising self-report questionnaires including the Cancer Therapy Satisfaction Questionnaire, Brief Fatigue Inventory, Functional Assessment of Cancer Therapy-Prostate, EuroQol-5-Dimensions and the Burden Scale for Family Caregivers (carers only). RESULTS: At the outset of therapy, men reported a willingness to take docetaxel to prolong their life, despite being fearful of the potential side effects and impacts on their daily lives. Patient and carer experiences were generally consistent with pre-treatment expectations. However, variations in individual experiences and their ability to tolerate side effects were evident. Fatigue emerged as a prominent symptom with the majority (n = 98, 60.9%) of men reporting experiencing moderate-severe fatigue in the past 24 h. Participant ratings of fatigue were strongly correlated with health-related quality of life (r = - 0.82). Nausea, diarrhoea and sore mouth were also among the most bothersome symptoms for participants. CONCLUSIONS: Findings from this study highlight that real-world experience of docetaxel may differ from that observed in clinical trials and that care must be taken to ensure that treatment options are tailored to the needs of individual patients to promote not only how long patients survive but also the quality of that survival.
