Detailed Description
Carcinomas of the salivary glands (SGC) are rare tumors. They comprise less than 1% of all cancers of the head and neck. The standard treatment is surgical excision, followed by radiotherapy in selected cases, such as high-grade tumors, and/or in the presence of perineural invasion, and/or in the presence of advanced disease. Some selected salivary gland histotypes such as salivary duct carcinomas (SDC) and adenocarcinomas, NOS (not otherwise specified) distinguish themselves for the expression of androgen receptors (AR), which is reported in 21% to 43% of the cases. Thus, similarly to prostate cancer (Pca), androgen deprivation therapy (ADT) has been suggested to be beneficial in patients with recurrent or disseminated AR-expressing disease.
The proven activity of ADT in AR expressing SGC as well as in Pca, suggests a common clinical behaviour by apparently sharing the same biological background. Once Pca becomes resistant to castration it still remains driven by ligand-dependent AR signaling and further hormonal manipulations are active and efficacious. Abiraterone acetate is currently approved by FDA for castration-resistant prostate cancer (CRPC). We treated with abiraterone two patients with AR-positive adenocarcinoma who had progressed on ADT, both patients showed a partial response suggesting the activity of a second line hormonal therapy in SGCs.
Based on the above biological and clinical evidences, the aim of the trial is to assess the activity of abiraterone in AR-expressing castration resistant SGCs.

Intervention / Treatment |
---|---|
Experimental: Abiraterone acetate
Abiraterone acetate 1 g/day must be taken as four 250-mg tablets daily on an empty stomach.
No food should be consumed for at least 2 hours before the dose of abiraterone acetate is taken and for at least 1 hour after the dose of abiraterone acetate is taken.
Prednisone (prednisolone when prednisone is not available) 5 mg will be given orally twice a day.

Abiraterone acetate is a prodrug of abiraterone, an irreversible inhibitor of 17α hydroxylase/C17, 20-lyase (cytochrome P450c17 [CYP17]), a key enzyme required for testosterone synthesis.
This enzyme is found in the testes, adrenals, prostate tumors
