Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Frequency of successful complete tumor excision by the BLES system. | Successful is defined as 'having tumor free margins, and no residual (in situ) cancer in the surgical specimen'. | Through study completion, an average of two months | |
Secondary | Quality of the margin evaluation of the biopsy specimen and the eventual surgical specimen. | Through study completion, an average of two months | ||
Secondary | In biopsy specimen in which the margin is not completely tumor free, but the Dutch criterion for successful surgery is met (no more than focal (4 mm) margin involvement), we will specifically analyse the residual tumor burden in the surgical excision. | Through study completion, an average of two months | ||
Secondary | Assess in retrospect whether we can predict successful tumor extraction based upon other factors than tumor size alone. | Parameters categorized in: Patient related variables obtained from a questionnaire Lesion related variables Imaging features Surgical features Histopathological and molecular features from the core biopsy |
