Conditions:

Triple Negative Breast Cancers Without Lymph-node Involvement and < or = 30 mm

Eligibility:

FEMALE

18+ years

Phase:

NA

Brief Summary

This is a prospective, non-randomized and multicenter study designed to compare biological features between pN0 triple negative breast cancer (TNBC) with size ≤ 10 mm (pT1a/b) versus pT1c T2 ≤ 30 mm. ...

Eligibility Criteria

Inclusion

  • Woman with age ≥ 18 years.
  • Patient who completed surgery for his breast cancer and for which definitive histo-pathological analysis of surgical specimen is available.
  • Invasive breast carcinoma pN0 or pN(i+) with histological tumor size ≤ 10 mm (pT1a/b subgroup) or invasive breast carcinoma with histological tumor size \> 10 mm and ≤ 30 mm (pT1c T2 ≤ 30 mm control group).
  • Patient with HER2-negative breast carcinoma: immuno-histochemistry (IHC) score = 0, 1+ or 2+ and in situ hybridization (FISH, CISH, or SISH) negative (local laboratory testing).
  • Patient with ER and PR negative invasive carcinoma (\< 1% stained cells by immuno-histochemistry assay) (local laboratory testing).
  • In case of multifocality, the histological size of the largest tumor must be ≤ 10 mm or ≤ 30 mm according to the inclusion subgroup. All lesions must be ER, PR and HER2-negative.
  • In case of breast conserving surgery, clear margins are required.
  • Patient affiliated to a Social Health Insurance in France.
  • Patient information and written informed consent form signed prior to any study specific procedures.

Exclusion

  • Patients with any previous malignancy of the breast or other site, with the exception of adequately treated basal or squamous cell carcinoma, non-melanomatous skin cancer totally resected.
  • Non-invasive breast carcinoma (i.e. ductal carcinoma in situ exclusively).
  • Inoperable breast invasive carcinoma.
  • Synchronous bilateral breast cancer.
  • Patients who received neo-adjuvant treatment (radiotherapy or chemotherapy or other before surgery).
  • Pregnant or breast-feeding women.
  • Any psychological, familial, geographic or social situation, according to the judgment of investigator, potentially preventing the provision of informed consent or compliance to study procedure.
  • Patient who has forfeited his/her freedom by administrative or legal award or who is under guardianship.
