We did not find studies that investigated these other potential reasons for variations between hospitals in the use of SLNB. Furthermore, it is unknown to what extent the patient has an influence on the decision to use SLNB. Also, the variation might be influenced by differences in how hospitals have organised the care for patients with DCIS, for instance how often they use a vacuum-assisted device as a diagnostic technique. įor the Netherlands, no data is available on diverging opinions of surgeons. Survey studies from the UK have shown that the opinions of surgeons deviated from the NICE guidelines, which state that extensive microcalcification or a palpable mass are indications for SLNB in case of breast conserving surgery. It can be hypothesized that variations between hospitals are associated with differences in surgeons interpretation of the treatment guidelines and in their level of agreement with these guidelines. Previous studies, showed differences between hospitals in the use of axillary evaluation or SLNB for DCIS. Several international guidelines have been developed to select patients with an increased risk. For this reason, staging with Sentinel Lymph Node Biopsy (SLNB) is considered in patients thought to be at high risk of a diagnosis of invasive breast cancer. Of the patients with a preoperative diagnosis of Ductal Carcinoma in Situ (DCIS), 20 to 25% will have a final diagnosis of invasive breast cancer after surgery.
