Integration of bone scan (BS) and computerized tomography (CT) findings as an endpoint to assess bone metastasis in metastatic castration-resistant prostate cancer (mCRPC).

191 Background: Progression of bone metastasis in mCRPC is assessed solely by BS findings and correlates modestly with overall survival (OS). Given the lack of reliability of BS findings and the ready availability of routinely performed CT scans, which commonly identify bone metastases, we aimed to better assess progression in bone by integrating BS and CT findings and to explore their association with OS. Methods: Data were …
