NCT04047459
The project aims at unraveling the role of organ-specific endothelia mediating the preferential metastasisation of breast cancer cells to bone by using a multi-faceted approach, integrating microfluidics and transcriptomic profiling. Based on a recently study published by the investigators \[Jeon et al., PNAS 2015\], it can be hypothesized that phenotypic differences at the level of organ-specific endothelial cells are able to drive the preferential extravasation of breast cancer cells to specific sites. Hence, the transcriptional profile of primary organ-specific endothelial cells derived from healthy patients (i.e. non-affected by breast cancer) will be analyzed to identify phenotypic differences between organ-specific populations of endothelial cells. These analyses will allow to identify potential target genes involved in the organ-specific extravasation of cancer cells (i.e. genes differentially expressed by endothelia of preferential and non-preferential metastasisation sites). The selected genes will be silenced and the effect of gene silencing will be evaluated through microfluidic in vitro organ-specific 3D models designed to study cancer cell extravasation.

In France, breast cancer affects approximately 53,000 new cases per year. The investigators have to take care more and more women with subclinical lesions (nonpalpable), and it represents around 25% to 35% of the diagnosed breast cancers. The main problem of the surgical management of these lesions is the quality of preoperative identification which determines the quality of surgery and oncological and cosmetic outcomes. For this type of lesion, SNOLL (Sentinel Node and Occult Lesion Localization) procedure could be proposed. This is a radioactive labeling of the tumor site and sentinel lymph node (SLN). The investigators want to evaluate the potential benefits of using a hand held camera called TreCam in this SNOLL procedure. This camera permits to obtain nuclear imaging at the bedside and in the operating theater.
