Abstract
Background
Primary endocrine therapy (PET) is a treatment option for elderly patients with ER-positive breast cancer enabling frail patients to avoid surgery. As a long-term treatment option, it has been shown to be inferior to surgery in controlling local disease. Decision-making in these patients is crucial in avoiding treatment failure. We examined the influence of decision-making on outcomes of PET failure as a secondary analysis as part of a large observational study.
Methods
Consecutive patients treated with PET between 2005 and 2015 for operable breast cancers were included in a retrospective observational study in 3 breast centres in the North-East. Treatment decision processes were examined by case note review and outcomes of treatment success or failure recorded.
Results
488 patients were included with mean follow-up of 31 months. Overall 63 (12%) experienced treatment failure. 227 (46.6%) were given a choice between surgery and PET at diagnosis. Logistic regression identified older age [OR 0.94 (0.91–0.96) p < 0.001] and reduced mobility [OR 0.6 (0.37–0.97) p 0.036] to be less likely offered surgery. Those offered surgery were more likely to experience treatment failure with PET [SHR 1.78 (1.05–3.02) p 0.033].
Conclusions
Despite a low failure rate in our series (literature failure rates vary between 12 and 85%), these results suggest that those actively offered a choice between surgery and PET are at greater risk of failure when choosing PET.
