BACKGROUND: Radium-223 is an alpha-emitting, bone-targeting radiopharmaceutical that confers a survival benefit in patients with confirmed bone-metastatic, castration-resistant prostate cancer with no visceral metastases. We studied real-world use of radium-223 in eligible patients from a tertiary hospital.
METHODS: We retrospectively collected clinical data of patients treated with radium-223 in Tungs' Taichung MetroHarbor Hospital by chart review. Data included biochemical parameters, pain scores, other prostate cancer treatments received and adverse events (AEs).
RESULTS: Of 36 patients included in the study, 12 patients received radium-223 as first-line therapy, 11 as second-line treatment and 13 as third-line treatment. Prostate-specific antigen significantly increased from baseline in patients who received radium-223 as third-line treatment and in patients who received radium-223 post-chemotherapy. Pain scores significantly decreased when radium-223 was given as second-line and as third-line treatment. In the patients who were naive to novel anti-hormone (NAH) therapy and chemotherapy, mean alkaline phosphatase level significantly decreased from baseline. The most common AE was anemia, found in 16.7% of patients.
CONCLUSION: Radium-223 had early biochemical benefits, while in the later stages of the disease, it reduced bone pain in this real-world cohort of chemotherapy-naive, NAH-naive patients, and patients with prior therapy, from a tertiary institution in Taiwan.
