Out-of-hospital follow-up after low risk breast cancer within a care network: 14-year results

The delegation of low-risk breast cancer patients' follow-up to non-hospital practitionners (NHP), including gynaecologists and general practitioners, has been assessed prospectively within a care network in the Paris region. Patients with early stage breast cancer were eligible. The follow-up protocol was built according to international guidelines. By 2012, 289 NHPs were following 2266 patients treated in 11 centres. Median follow-up time was 7.4 years. The mean intervals between two consecutive consultations were 9.5 [9.2-9.8] months for women supposed to be monitored every 6 months and 12.5 [12.2-12.8] for those requiring annual monitoring. The relapse rate was 3.2% [2.1-4.3] at 5 years and 7.8% [5.9-9.7] at 10 years. Seventy one percent of relapses were diagnosed on a scheduled assessment. Only 6% were lost-to-follow-up. Delegating follow-up after low risk breast cancer to NHPs in a care network is feasible, well accepted and provides an alternative to follow-up in specialized centres.
