Use of an Additional Diagnostic Work-up Following a Treatment Recommendation from the Preoperative Conference of the Mammography Screening Units.
2014
Objective: If a focus of suspicion is classified as being B 3–5 by a punch biopsy as part
of a mammography screening, a recommendation for further action to be taken will be given in the
preoperative conference of the screening unit. As part of this investigation, these treatment
recommendations were compared with the final therapeutic approach taken at a certified breast
centre. Furthermore, it was investigated whether and which additional examinations were
performed on patients, depending on compliance with the recommended treatment. Material and
Method: The data from 272 breast cancer patients from the years 2007, 2008 and 2009 was
analysed. The patients took part in the screening programmes of four screening units in the
German mammography screening programme, in one federal state. In addition, the data from each
patient from one screening unit was analysed in two further federal states. Results: In
total, the most recently conducted intervention deviated from the treatment recommendation from
the preoperative conference in the screening unit in 77 out of 272 patients (28.3 %). Of these,
there were 50 recommendations for open biopsy which ultimately resulted in breast-conserving
surgery, which is not to be evaluated as an error, as the bioptic result was supplemented by the
open biopsy. Additional examinations were performed in patients with deviating treatment
recommendation in 39 cases (50.6 %) and in patients without deviating treatment recommendation
in 66 cases (34.0 %). The additional examinations carried out included additional punch biopsies
(most frequent) and MRI scans, but also additional ultrasounds or a mammography.
Conclusions: Additional examinations lead to a change in treatment in a higher
percentage of patients in comparison with the initial screening including assessment. An exact
reexamination of the findings obtained in the screening is therefore preoperatively necessary in
order to guarantee optimum treatment.
