About this trial
This is an interventional basic science trial for Breast Cancer Female focused on measuring PDX
Eligibility Criteria
Inclusion Criteria:
- ECOG (Eastern Cooperative Oncology Group) performance status ≤ 2
- Signature of the participation consent to the study,
- Affiliation to a social security scheme
Major woman with:
- metastatic triple-negative (TN) breast cancer, histologically proven before treatment and high grade, receiving neoadjuvant chemotherapy and having, after treatment, a breast residue of at least 15 mm on the specimen. The mammary residue will measure at least 15 mm on the mammography performed at the end of neoadjuvant treatment
- metaplastic triple-negative (TN) breast cancer, histologically proven before treatment and high grade, treated by primary surgery with a tumor size of at least 15 mm on the specimen.
- an inflammatory TN breast cancer (T4d), histologically proven prior to treatment, receiving neoadjuvant chemotherapy and having, after treatment, a breast residue of at least 15 mm on the specimen. The mammary residue will measure at least 15 mm on the mammography performed at the end of the neoadjuvant treatment.
- non-metaplastic or inflammatory TN breast cancer, histologically proven prior to treatment, receiving neoadjuvant chemotherapy and having, after treatment, a mammary residue of at least 30 mm on the specimen. The mammary residue will measure at least 15 mm on the mammography performed at the end of the neoadjuvant treatment.
- Luminal B breast cancer (LB), histologically proven prior to treatment, receiving neoadjuvant chemotherapy and having, after treatment, a mammary residue of at least 30 mm on the specimen. The mammary residue will measure at least 15 mm on the mammography performed at the end of the neoadjuvant treatment.
- histologically proven metastatic TN or metastatic breast cancer with an operable metastasis whose residual size, after chemotherapy, is at least 10 mm on the specimen. Residual metastasis will be at least 15 mm on imaging.
- Patients in a metastatic situation can be included regardless of the therapeutic line.
Exclusion Criteria:
- Pregnant woman
- Patient deprived of liberty by court or administrative decision
- In neoadjuvant situation: no neoadjuvant treatment by radiotherapy or hormone therapy
- Refusal to participate in the study

Arms of the Study
Arm 1
Arm Type
Other
Arm Label
Succeed PDX
Arm Description
Genetic analysis will be performed in patients who got a successful PDX
Outcomes
Primary Outcome Measures
Percentage of successfull PDX
PDX will be realized from patient tumor by transplanting a small fragment in a nude mouse. Once the tumor is enough grown up, the tumor is extracted to repeat this step 3 times until we get the fourth PDX with a successful tumor growth.
Secondary Outcome Measures
Histological subtype
Comparaison of initial tumor histological subtype with PDX histological subtype
expression of estrogen receptors
Comparaison of initial tumor expression of estrogen receptors with PDX expression of estrogen receptors
expression of progesterone receptors
Comparaison of initial tumor expression of progesterone receptors with PDX expression of progesterone receptors
status of the amplification of the ERBB2 gene
Comparaison of initial tumor's ERBB2 gene amplification status with PDX's ERBB2 gene amplification status
expression of androgen receptors
Comparaison of initial tumor expression of androgen receptors with PDX expression of androgen receptors
tumor molecular classification
Comparaison of initial tumor molecular expression with PDX molecular classification (luminal A, luminal B, HER2 enriched or triple negative)
Exome sequencing
Comparaison of genetic alterations between intial tumor, PDX and blood sample

5. Study Description
Brief Summary
Patient derived xenografts (PDX) from mammary tumors are usually made from metastatic tumors. Indeed, PDX from primitive mammary tumors or after neoadjuvant treatment are still rare. However, the realization of such PDX (from primitive mammary tumors or after neoadjuvant treatment) would make it possible to have a better knowledge of the tumor heterogeneity to the therapeutic response, to explore the models of tumor evolution during metastatic progression and also observe the mechanisms of tumor resistance in the case of non-metastatic tumors. It therefore seems necessary to develop PDX from primitive tumors in order to observe firstly the success rate of PDX; on the other hand, the drift of the initial heterogeneity, measured by comparison of the histomolecular profile of the tumors with that of the PDXs. It aims to develop xenografts from tumor samples from surgical specimens of patients with triple negative or luminal B breast cancer.
