In both treatment arms, we observed significant trends for lower adherence with increasing severity for all symptoms (P < .01) except headaches (P = .054). Conclusion: In the IBIS-I trial, experiencing predefined symptoms in the first 6 months reduced long-term adherence. Effects were similar between treatment arms, suggesting that women were attributing age-related symptoms to preventive therapy. Interventions were required to support symptom management.]]> Wed 11 Apr 2018 12:50:17 AEST ]]> Use of anastrozole for breast cancer prevention (IBIS-II): long-term results of randomised controlled trial https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41264 vs 165 cases, hazard ratio [HR] 0·51, 95% CI 0·39–0·66, p<0·0001). The reduction was larger in the first 5 years (35 vsvsvs 70, HR 0·96, 95% CI 0·69–1·34, p=0·82) or for breast cancer (two anastrozole vs three placebo). A significant decrease in non-breast cancers was observed for anastrozole (147 vs 200, odds ratio 0·72, 95% CI 0·57–0·91, p=0·0042), owing primarily to non-melanoma skin cancer. No excess of fractures or cardiovascular disease was observed. Interpretation: This analysis has identified a significant continuing reduction in breast cancer with anastrozole in the post-treatment follow-up period, with no evidence of new late side-effects. Further follow-up is needed to assess the effect on breast cancer mortality.]]> Fri 11 Aug 2023 16:56:23 AEST ]]>
