A systematic review and a meta-analysis of randomized trials. PG - 68-75 LID - S1040-8428(19)30148-9 [pii] LID - 10.1016/j.critrevonc.2019.07.013 [doi] AB - BACKGROUND: Zoledronic Acid is a bisphosphonate used in a 4-week schedule for the treatment of bone metastases. Some randomized trials supported its role also when administered every 12 weeks. METHODS: we performed a systematic review and a meta-analysis in order to evaluate the two different schedules in terms of skeletal morbidity rate (SMR), skeletal related events (SRE) and adverse events (AEs). RESULTS: our results showed a clinical difference favouring the 12-week schedule in terms of AEs (RR 1.17, 95% CI 1.06-1.29). No signifcant differences were found for SMR (RR 0.97, 95% CI 0.84-1.13) and SRE (RR 1.02, 95% CI 0.89-1.16). CONCLUSIONS: Our findings support in clinical practice the 12-week schedule an alternative to the standard 4-week schedule in advanced breast and prostate cancer, in particular when the clinical comorbidities of the patients suggest a higher risk of renal failure or hypocalcaemia.
