Phenotypic Characterization Tumor-infiltrating Lymphocytes at Diagnosis and After Chemotherapy in Ovarian Cancer (TILsOV-1805)

February 8, 2024 updated by: Centre Oscar Lambret

Phenotypic Characterization Tumor-infiltrating Lymphocytes at Diagnosis and After Chemotherapy in Advanced High-grade Serous Ovarian Cancer in Blood, Ascites, Peritoneal Biopsy

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.

Study Overview

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

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Counting of lymphocyte populations (pre-chemotherapy)
Time Frame: At diagnosis (during diagnostic laparoscopy, which is : before chemotherapy (pre-CT) and up to 1 month after enrollment)
For each sample taken (blood / ascites / peritoneal carcinomatosis fragment), before chemotherapy, the lymphocyte populations will be counted by flow cytometry (CMF). For this, 4 panels of 32 markers will be used to identify 5 populations of lymphocytes: Thelper, B lymphocytes, TREG, TFH, TCD8, and immuno checkpoint
At diagnosis (during diagnostic laparoscopy, which is : before chemotherapy (pre-CT) and up to 1 month after enrollment)
Counting of lymphocyte populations (post-chemotherapy)
Time Frame: At the end of chemotherapy (post-CT), up to 3 months
For each sample taken (blood / ascites / peritoneal carcinomatosis fragment), at the end of chemotherapy, the lymphocyte populations will be counted by flow cytometry (CMF). For this, 4 panels of 32 markers will be used to identify 5 populations of lymphocytes: Thelper, B lymphocytes, TREG, TFH, TCD8, and immuno checkpoint
At the end of chemotherapy (post-CT), up to 3 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Histological type on the initial biopsy
Time Frame: At diagnosis, before chemotherapy (pre-CT), up to 1 month after enrollment

At diagnosis, before chemotherapy (pre-CT), up to 1 month after enrollment
