Impact of Androgen Deprivation Therapy on Sexual and Hormonal Function in Patients Receiving Radiation Therapy for Prostate Cancer.

Androgen deprivation therapy (ADT) added to radiation therapy (RT) in intermediate to high risk prostate cancer negatively impacts quality of life.

To compare health-related quality of life (HR-QOL) in patients receiving combined RT with and without ADT METHODS: The study population comprised patients treated with definitive RT for prostate cancer who completed the Expanded Prostate Cancer Index Composite-26 form between 3 and 24 months after completing RT. Covariance and a stepwise backward logistic regression model was used.

Data were available for 143 patients who received RT+ADT and 70 who received RT alone. The sexual function and hormonal vitality scores of patients receiving RT+ADT were significantly lower than those receiving RT alone (P < 0.0001). Patients with only compulsory school education had significantly lower sexual function scores than patients with university level education (P ≤ 0.005). Patients with depression had significantly lower hormonal vitality scores than those without depression (P ≤ 0.0001).

The addition of ADT to RT is responsible for decrements in quality of life in the sexual and hormonal vitality domains, which is further compounded by depression and lack of education. This underlines the need to improve education, identify and treat depression, and develop strategies to improve the quality of life of patients receiving combination therapy.
