Schildwachtklierbiopsie bij patiënten met mammacarcinoom: aanbevelingen voor de introductie van deze techniek

- Sentinel node biopsy may be useful in the staging of breast cancer. In experienced hands presence or absence of metastasis in the sentinel node accurately predicts the nodal status and in patients with a negative sentinel node biopsy axillary dissection may be avoided. The technique, however, shows a clear learning curve and hasty introduction may lead to an unacceptable rate of false negative biopsies. Moreover, the introduction of the technique in general practice should be well coordinated in order to prevent large differences between hospitals in the staging and treatment of breast cancer patients. On the initiative of NABON (Nationaal Borstkanker Overleg Nederland; ‘national breast cancer consultation’) and the Nederlandse Vereniging voor Chirurgische Oncologie (Netherlands Association for Surgical Oncology) a study group was formed to co-ordinate the introduction of the sentinel node biopsy in breast cancer patients in the Netherlands. Important topics are central registration of all procedures in order to evaluate its applicability and technical variations, the performance in each centre of at least 50 procedures together with axillary node dissection to evaluate the results before clinical application is considered, and nationwide co-ordination to find the best therapy for patients with positive sentinel nodes.
