Salivary duct carcinoma (SDC) is a rare, aggressive salivary gland malignancy with limited evidence guiding standard treatment. SDC is known to overexpress the androgen receptor, with only a handful of cases reporting responses to androgen blockade. This report presents a case of SDC responding to multiple lines of androgen blockade, including a rapid response to abiraterone, a CYP17 inhibitor effective in prostate cancer. This case represents the first published report of SDC responding to abiraterone and illustrates that androgen receptor expressing SDC may be treated with multiple lines of androgen blockade, including newer agents such as abiraterone. This case suggests that SDC may continue to be androgen-dependent after progression on androgen deprivation, which is analogous to prostate cancer.

Background: During the past 2 decades, numerous clinical trials have focused on improving outcomes in patients with metastatic pancreatic cancer (mPDAC). The efficacy of new treatments has been demonstrated among highly selected patients in randomized phase III trials; hence, it is not clear to what extent these advances are reflected within the broader mPDAC population. Materials and Methods: Survival statistics were extracted from the SEER database for patients diagnosed with mPDAC between 1993 and 2013. Survival was analyzed using the Kaplan-Meier method and proportional hazard models. Results: The study population consisted of 57,263 patients diagnosed with mPDAC between 1993 and 2013; 52% were male, with a median age of 69 years (range, 15–104). Superior prognosis correlated with younger age, being married, tumor located within the head of the pancreas, lower grade disease, and more recent year of diagnosis. Median overall survival (OS) remained stable at 2 months between 1993 and 2013. Improvements in OS were seen for younger patients (age <50 years) and those with a more recent year of diagnosis (2009–2013). The percentage of patients who died within 2 months of initial diagnosis decreased between 1993 and 2013 (from 63.5% to 50.6%; P<.0001). The percentage of patients surviving ≥12 months improved from 4.9% in 1993 to 12.7% in 2013 (P<.0001). Conclusions: In recent years a modest improvement in OS has been seen among younger patients with mPDAC. The percentage of patients living beyond 1 year has significantly increased over time; however, the percentage of those dying within 2 months remains substantial.
