Predictive Value of Progastrin Titer at Diagnosis and of Progastrin Kinetics During Treatment in Cancer Patients

Study Overview
=================
Brief Summary
-----------------
Progastrin is a pro-hormone that, in physiological conditions, is maturated in gastrin in G cells of the stomach. The role of the gastrin is to stimulate the secretion of gastric acids during digestion. It is also important for the regulation of cell growth of the gastric mucosal. In a healthy person, progastrin is not detectable in the peripheral blood. However, progastrin is abnormally released in the blood of patients with different cancers (colorectal, gastric, ovarian, breast, cervix uterus, melanoma…) The gene GAST coding for progastrin is a direct target gene of the WNT/ß-catenin oncogenic pathway. The activation of this oncogenic pathway is an early event in cancer development. Chronic activation of the WNT/ß-catenin oncogenic pathway occurs in almost all human solid tumors and is a central mechanism in cancer biology that induces cellular proliferation, blocking of differentiation leading to primary tumor growth and metastasis formation. Progastrin measured in the peripheral blood of patients on treatments, could be a new powerful marker for diagnosis and prognosis at different stages.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: Cancer patients<br>420 patients affected by different types of cancer and treated in a curative or a palliative intent. In total 17 cohorts will be open, including: breast cancer, head and neck carcinomas, renal cell carcinoma, prostate carcinoma, lung carcinoma, hepatocellular carcinoma, colorectal carcinoma, thyroid cancer, pancreatic adenocarcinoma, ovarian adenocarcinoma, glioblastoma, endometrial adenocarcinoma, bladder carcinoma, oesophago-gastric carcinoma, B-cell lymphoma, gastric carcinomas. Patients enrolled in curative intent treatment cohorts will never have been previously treated for their cancer. Patients enrolled in non-curative intent treatment cohorts will have never been treated for their metastatic cancers previously, or have developed advanced/metastatic diseases as relapses of localized cancers previously treated with curative intent therapeutic strategies. Other cohort will be open (stability cohorts) : nychtemer cohort and post-operative kinetic cohort. | Other: Blood draws<br>* Blood draws are realized at each steps of patient disease management. The volume of each blood drawn is 25 mL for progastrin measurements and 5 mL for the dosage of the other tumor markers. The frequency depend to the cancer and treatment administered : Baseline at diagnosis : Local radical treatment : within 24h before surgery, within 24h after surgery and at the post-surgery follow up visit Chemotherapy treatment : every 3 or 4 weeks Radiotherapy : start day and at the end of radiation (end of treatment visit) Palliative systemic treatment (only palliative cohorts) : every 3 to 12 weeks. Follow until the third progression or change of treatment line, or alternatively up to 5 years after inclusion In case of PD or TOX Follow up: at each visit scheduled (every 3 months) for the first 2 years, then every 6 months for 3 years Relapse : withdrawn from the study and last progastrin measurement. Patient could be enrolled in the non-curative intent cohort<br>|
