Docetaxel in hormone-sensitive advanced prostate cancer; GENESIS-SEFH evaluation reporta.

Prostate cancer (PC) is the most common urogenital malignancy in older men and the second leading cause of death by cancer in men in Europe. Current therapeutic practice considers Androgen Deprivation Therapy (ADT) as first line treatment for clinically localized prostate cancer at high-risk, either locally advanced or metastatic. ADT can be achieved through orchiectomy (surgical castration), luteinizing hormone-releasing hormone (LHRH) agonists, or through complete androgen blockade (LHRH agonist combined with an anti-androgen). Docetaxel in combination with prednisone or prednisolone is indicated for the treatment of patients with hormone-refractory metastatic prostate cancer. The CHAARTED and STAMPEDE clinical trials studied the effect of bringing forward the use of docetaxel added on to ADT in the context of hormone-sensitive patients. The CHAARTED clinical trial showed a significant increase in a variable with maximum relevance such as Overall Survival (OS), with a difference of 13.6 months between medians. There was also clinical benefit in the secondary variables: median time until castration-resistant disease or until clinical progression. In the STAMPEDE clinical trial, which included 39% of non-metastatic patients, a 10-month difference between medians was demonstrated in OS, and 17 months in the primary co-variable of Progression Free Survival. The most frequent adverse events were: neutropenia, febrile neutropenia, leucopenia, and general disorders such as asthenia, lethargy or fever. According to data from the CHAARTED and STAMPEDE studies, and the incremental cost of € 3 196.98 for adding on docetaxel to standard treatment, the estimated additional cost for each year of life gained is compatible with an incremental cost-effectiveness ratio between € 2 267.36 and € 3 851.78. In view of the efficacy and safety results, the proposed positioning is: to advance the use of docetaxel added to androgen deprivation therapy to first-line metastatic hormone-sensitive prostate cancer, regardless of metastatic volume, in those patients who meet the CHAARTED study criteria.
