Colleen, yes, I was diagnosed at Mayo with salivary duct carcinoma of the parotid gland with distant metastasis stage 4. The cancer tested androgen receptor positive. I am 10 weeks into 12 weeks of my first treatment – androgen deprivation therapy or hormone therapy. Only mild side-effects. Decisions on staying the course or changing therapies are upcoming this month. Sylvia’s husband is the only person I have found to have the same cancer. It would be helpful to hear from others with this rare cancer. Thanks.
