324 Background: Androgen deprivation therapy (ADT) remains a standard of care in the treatment of locally advanced prostate cancer. But thanks to a few key trials (STAMPEDE, CHAARTED, and LATITUDE) reported within the past three years, docetaxel and abiraterone now have roles in extending overall survival in a patient population traditionally treated with ADT alone. These treatments when combined with ADT have been shown to extend overall survival in metastatic hormone-sensitive prostate cancer patients. The role of ADT in relation to other therapies continues to evolve rapidly. We intend to revisit ADT’s longstanding role in prostate cancer treatment using a national cancer database. Our aim is to look beyond traditional standards of care to identify patients more likely to have overall survival benefit from ADT. Are there any subgroups of patients with intermediate or high risk disease that have improved survival outcomes with androgen deprivation therapy, besides patients with localized disease that underwent radiation? Could there be other variables besides PSA and localization of the prostate cancer that should be considered when identifying ADT treatment candidates, or identifying survival trends in these groups? Methods: We are currently analyzing variables present in the National Cancer Database to retrospectively identify predictive factors for overall survival and progression to metastatic castrate resistant prostate cancer in locally advanced prostate cancers treated with ADT. We will evaluate time-to-death from the initiation of ADT and from the diagnosis of metastatic castrate resistant prostate cancer. The following variables in localized, locally advanced, and metastatic prostate cancer will be analyzed with Statistical Analysis Software: age, locally advanced, site-specific metastasis (M1a, M1b, M1c), Gleason score, local treatment (radical prostatectomy or radiation), stage (T, N, and M), prostate lobe (one vs. both; T2a/b vs. T2c), chemotherapy (date, time from M1 stage), comorbidity score, ethnicity, facility type, insurance, and risk groups (low/intermediate/high as per NCCN guidelines).
