The study demonstrated that a dose of 40 and 50 MBq/kg of Re-188-HEDP was effective in alleviating pain and improving QOL in lung cancer patients with bone metastases, and it was safe and well-tolerated by the patients.
Purpose To investigate the pain-relieving effect and safety of three different doses of Re-188-hydroxyethylidine diphosphonate (HEDP) in patients with lung cancer and bone metastases. Methods For this randomised, phase 2 and multicenter trial, we enrolled patients with lung carcinoma and multifocal bone metastases and excluded patients who had received bisphosphonates or external-beam radiotherapy within the previous 4 weeks. Fifty-four patients were randomized to receive a single injection of Re-188-HEDP, at doses of 30, 40 or 50 MBq/kg (interval, 12 weeks). Patients were followed-up by assessment of numerical rating scale (NRS) score, global quality of life (QOL) score and adverse events (AEs). ANOVA analysis, Chi-Squared test and LSD-t test were used in this study. Results Significantly decreased NRS scores relative to baseline were observed in 40 MBq/kg group (Week 0 vs. Week 12: 6.0 +/- 1.4 vs. 4.8 +/- 2.5, P = 0.033) and 50 MBq/kg group (Week 0 vs. Week 12: 5.5 +/- 1.5 vs. 4.5 +/- 2.9, P = 0.046). Significant change of global QOL score from baseline was observed in 40 MBq/kg group at week 8 (global QOL score: P = 0.024, pain score: P = 0.041) and 50 MBq/kg group (pain score: P = 0.021) at week 12. No patients withdrew trial because of AEs in three groups. Conclusions Re-188-HEDP at dose of 40 and 50 MBq/kg was generally effective to alleviate pain and improve QOL in lung cancer patients with painful bone metastases. Re-188-HEDP was safe and well-tolerated.
