Circulating neuromediators in chemotherapy-naïve CRPC patients were elevated in a high percentage of patients. ADT was found to be a relevant NED driver in this cohort. Our results may imply that patients with CRPC after first-line treatment with AA in CRPC are not at a higher risk for developing NED. The major limitation of the study represents the one-time analysis of neuromediators. Larger studies with serial blood measurements or biopsy analysis before and after treatment are needed to confirm our results.
Patients with an early high CGA rise may demonstrate a subgroup with poor outcome due to underlying SCNC transformation. Monitoring of CGA appears to be an option worth considering.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
