Objective: Androgen deprivation therapy (ADT) is the main treatment for metastatic hormone-sensitive prostate cancer (mHSPC). Fatigue and loss of sleep quality are the side effects of ADT, which reduces the quality of life in these patients. Aromatherapy is one of the complementary and alternative medicines (CAM) that are effective on psychological indices.

Patients and Methods: In an A1B1A2B2 study, from February to September 2019, a 64-year-old man treated with methadone, with diagnosis of localize prostate carcinoma after radical prostatectomy and receiving ADT was selected through Respondent-Driven Sampling (RDS). The patient was treated with underwent aromatherapy massage in two three-week stages (B1 and B2) and received Routine Therapy in the other two stages (A1 and A2). The effectiveness of treatment on two indices of sleep quality and fatigue severity was considered as primary outcomes and the association of two indices was considered as secondary outcomes. Data were analyzed by means of a generalized estimation equation (GEE) and repeated measures correlation (rmcorr) through IBM SPSS Statistics Version 20.

Results: Primary outcomes showed that aromatherapy massage was associated with improvement in sleep quality and decreased fatigue (p<0.01). Secondary outcomes also showed that there was a significant negative relationship between sleep quality and fatigue severity (p<0.05).

Conclusions: The results of this study, while confirming the effectiveness of aromatherapy on psychological aspects in a patient with cancer, can be promising in designing new therapeutic in CAM and be used by oncology setting.
