NCT04504747

Brief Summary

The present project aims at identifying robust candidates for drug resistance in BC patients eligible for NAC. Its originality lies upon the combination of three different and complementary prospective approaches: from the molecular analyses of biopsies sampled before and after NAC, from in vitro BC Patient-Derived Organoids (PDO) mimicking patient's response to NAC, and from Circulating Tumor Cells (CTCs) isolated before/during/after NAC.

Outcome Measures

Primary Outcomes (1)

  • Identify robust candidates - "innate, "acquired stable" and/or reversible"

    comparison of pre and/or post NAC molecular profiles in tumors, PDO models and CTCs - will be targeted with a drug in relevant models

    5 years

Secondary Outcomes (4)

  • public repertoire of whole transcriptome and targeted-NGS

    5 years

  • Identify molecular signatures associated with response to NAC

    5 years

  • Establish PDO samples exposed to NAC

    5 years

  • Evaluation of CTCs features

    5 years

You may qualify if:

  • Woman over 18
  • Signed consent to participate
  • Invasive mammary adenocarcinoma proven histologically and / or cytologically
  • Indication of CNA retention by the referring clinical team.
  • No contraindication to CNA.
  • Selected indication of the post-CNA surgery sequence, then radiotherapy

You may not qualify if:

  • Planned therapeutic sequence: CNA, followed by neoadjuvant radiotherapy (HIST-RIC clinical trial for example) before surgery
  • Metastatic disease at diagnosis
  • Patient relapsed from breast cancer precede
  • Other malignant disease in the previous 3 years, with the exception of cervical carcinoma in situ or skin basal cell carcinoma and any other cancerous pathology considered to have been properly treated and at low risk of relapse.
  • Woman pregnant or likely to be (without effective contraception) or breastfeeding
  • Person in an emergency situation, adult person subject to a legal protection measure (adult under guardianship, guardianship or legal protection), or unable to express consent.
  • Inability to undergo medical monitoring of the trial for geographical, social or psychological reasons
