Phenotypic Characterization Tumor-infiltrating Lymphocytes at Diagnosis and After Chemotherapy in Ovarian Cancer
Official Title
Phenotypic Characterization Tumor-infiltrating Lymphocytes at Diagnosis and After Chemotherapy in Advanced High-grade Serous Ovarian Cancer in Blood, Ascites, Peritoneal Biopsy
Brief Summary
This is a monocenter, interventional, non-randomized study among women patients with an
ovarian or tubal cancer who will receive a surgery or adjuvant chemotherapy treatment, or a
neo-adjuvant chemotherapy then surgery +/- adjuvant chemotherapy. The planned interventions
are collection of biological samples at different times. The study will aim to describe the
immunological profile at diagnosis in terms of phenotypic : PBMCs (peripheral blood,
mononuclear cells) in peripheral blood, TILs (tumor-infiltrating lymphocytes) in ascites and
in carcinomatosis.
Detailed Description
Participants will receive the following interventions because they are enrolled in the study:
blood sample collection
- at diagnosis, before chemotherapy (pre-CT)
- after chemotherapy (post-ct)
Two additional blood samples will be collected in each patient : one at diagnosis and one at
the end of chemotherapy.
The aim of this study is to describe the immunological profile at diagnosis in terms of
phenotypic : PBMC in peripheral blood, TILs in ascites and in carcinomatosis, in patients
treated for peritoneal carcinomatosis of ovarian or tubal origin. The treatment has to be a
surgery and an adjuvant chemotherapy, or a neo-adjuvant chemotherapy followed by a surgery
+/- adjuvant chemotherapy.
Other objectives of the study include:
- Evaluate the association between the immunological profile at diagnosis and the
characteristics of the disease at diagnosis (histological type, extension)
- Evaluate the prognostic value of the immunological profile at diagnosis in terms of
clinical response to neoadjuvant chemotherapy (for patients with interval surgery)
- Evaluate the polarization of the immune response induced by chemotherapy, describing the
phenotypic changes in the different types of samples (blood, +/- ascites, +/-
carcinomatosis) after chemotherapy in comparison with samples at diagnostic
- Evaluate the association between these immunological phenotypic changes and the clinical
response to chemotherapy in patients receiving neoadjuvant chemotherapy
- Collect biological material for peritoneal carcinomatosis for subsequent biological
analyzes
