About this study

In order to allow Tunisian patients with breast cancer to access immunotherapies, and innovative treatments to extend life expectancy of patients with breast cancer with a poor prognosis, it is important to study the epidemiological profile of Tunisian cancers breast, in terms of PD-L1 expression, tumor mutational burden (TMB), microsatellite instability status (MSI) and rate of TILs, in metastatic and locally advanced cases, in Tunis, over a one-year follow-up period.

It is also important to study other inflammatory and tumor biomarkers which would have a prognostic or even therapeutic value:

  • serum dosage of LDH (lactate dehydrogenase)
  • IL-6 (interleukin 6)
  • CRP (C-reactive protein)
  • absolute count of lymphocytes (CLA) and eosinophils
  • quantification of circulating tumor DNA before treatment and under treatment. The primary objective id to identify the epidemiological profile of the biological signature (PD-L1 / TMB / MSI/HRD/ TILs) of patients with locally advanced or metastatic breast carcinoma before and during the systemic treatment.

How can a doctor refer a patient or contact the research team?

Contact Monia Malek, MD (00216 28 101 505, monia.malek@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?
