Molecular Characterization of CTCs and ctDNA in Blood and Plasma Samples From Patients With Metastatic and/or Hormone-Resistant Prostate Cancer
Stopped early
Conditions studied: Hormone-Resistant Prostate Cancer, Metastatic Prostate Carcinoma
In brief
This research trial studies molecular characterization of circulating tumor cells (CTCs) and circulating tumor (ct) deoxyribonucleic acid (DNA) in blood and plasma samples from patients with prostate cancer that has spread to other places in the body and/or has not responded to previous treatment with hormones. Studying samples of blood and plasma collected from patients with prostate cancer before, during, and/or after treatment in the laboratory may help doctors learn more about changes that occur in DNA and identify the development of drug resistance.

You may qualify if…
- GROUP I: Samples for Group I will be selected from existing sample sets obtained from concluded studies (USC IRB #'s 10-00006 and 11-00450)
- GROUP I: Excess plasma collected and stored in these trials from patients treated with abiraterone or enzalutamide will be used for the molecular analysis of the current protocol
- GROUP II: The second group of samples (Group 2) will involve prospective collection of peripheral blood from patients with advanced, treatment-resistant metastatic prostate cancer
- GROUP II: Histologic documentation of prostate cancer
- GROUP II: Metastatic cancer diagnosed by imaging and other clinical criteria
- GROUP II: Treatment-resistance determined by at least one of the following factors: increase in prostate-specific antigen (PSA) value over a baseline measurement; increase in size or number of metastatic deposits determined on imaging; and/or progression in cancer related symptoms
