| Ovarian Cancer Stage IIIC Fallopian Tube Cancer Stage IIIC Fallopian Tube Cancer Stage IV Ovarian Cancer Stage IV | Procedure: Blood sample collection | Not Applicable |
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

- 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
- 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
- Histological type on the initial biopsy [ Time Frame: At diagnosis, before chemotherapy (pre-CT), up to 1 month after enrollment ]To check if there is an extension to the pleura (FIGO-IV) or not (FIGO-IIIC)
- Clinical response to chemotherapy (post-chemotherapy) [ Time Frame: At the end of chemotherapy, up to 3 months ]In patients receiving neo-adjuvant chemotherapy, clinical response to chemotherapy defined by a partial or complete radiological response (assessed on the thoraco-abdominopelvic CT scan), associated with a decrease in CA125 and a disappearance of ascites in case of ascites at inclusion
- Histological response to chemotherapy (no residual disease on excised tissue) [ Time Frame: At the surgery, an average of 6 weeks after inclusion ]Rate of patients with no residual disease on excised tissue regarding the assessment of histological response to chemotherapy
- Progression-free survival [ Time Frame: 6 months min to 14 months max ]Time between the diagnosis and the progression of the disease or the death of the patient, whatever the cause
- Global survival [ Time Frame: 6 months min to 14 months max ]Time between diagnosis and death, whatever the cause
