---|---|
Experimental: Microscopy confocal
|
Surgical margins of tumor samples will be examined by conventional histopathology (H&E) and confocal microscopy (Histolog® scanner, SamanTree Medical, Switzerland). Depending on the histopathological result obtained between the two methods, the patient may benefit directly from early surgery if the experimental result confirms the presence of positive margins (excluding the learning curve). A learning curve will be established over the first fifteen surgeries, enabling surgical teams to gain experience and systematize specimen flattening. This learning curve will also enable reference images to be produced. The procedure will be carried out by the surgeon and the pathologist in the operating room during this phase. |

Sensitivity and Specificity of Confocal Microscopy Diagnosis Compared to Gold Standard
Time Frame: 1 day
|
The concordance of intraoperative diagnosis between the two methods will be assessed by the condition of the margins of surgical specimens. Diagnostic accuracy will be measured by the sensitivity and specificity of confocal microscopy, using conventional histology reports from extemporaneous examination as the gold standard.
