A fragment of Breast/Ovarian tumors will be taken from a specimen or a cold biopsy, tissue from patients diagnosed with breast cancer or ovarian cancer before starting an induction treatment stage IIIc and IV pleural IFGO operable.
* Culturing the cells obtained from the tumor fragment by Oncomedics in a defined medium and provided for enriching tumor cells compared to stromal cells.
* Maintaining the cells in culture for 7 days.
* Effects of conventional chemotherapy (corresponding to protocols) on these cells for 72 hours (growth chambers) by Oncomedics (chimio-oncogramme).
* For each chemotherapy tested, measuring the proportion of dead cells / total cells.
* Retained by Oncomedics results, not given to the nursing team. The patient will be treated and followed up in the usual way.
* At the end of the study, comparing the in vitro results (chimio-oncogramme) to the patient response to the same chemotherapy.
