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.

can be included. lung carcinomas treated by immunotherapy : • non-curative intent patients cohort: o nsclc stage iv according to 8th tnm classification planned to be treated with immunotherapy, with/ without chemotherapy lung carcinomas excluding those treated with immunotherapy: * curative intent treatment patients cohort: o nsclc histology only o stage i-ii according to 8th tnm classification o stage iiia-b according to 8th tnm classification o planned to be treated with radical treatment (surgery or radiotherapy with/without concurrent chemotherapy), potentially associated with neo-adjuvant or adjuvant treatment * non-curative intent patients cohort: * nsclc or sclc stage iv according to 8th tnm classification planned to be treated with a first line of chemotherapy, with/without associated treatments except immunotherapy (radiotherapy, targeted therapies...). immunotherapy can be administrated for the subsequent lines of treatment. hepatocellular carcinomas a pathology proof of hcc is not necessarily provided if patients present typical radiologic characteristics of hepatocellular carcinoma on imaging * absence or chronic hepatic encephalopathy, absence of refractory ascites * curative intent treatment patients cohort: * indication of a treatment strategy with curative intent, except liver transplantation: surgical resection, monopolar radiofrequency ablation for hcc (1 to 3 nodules ≤3 cm) or multibipolar radiofrequency if nodule ≤4 cm). • non-curative intent patients cohort: * indication of a treatment strategy with no curative intent: transarterial intra-hepatic chemoembolization, targeted therapies (tyrosine kinase inhibitors or monoclonal antibodies) or immune therapy. colorectal carcinomas • curative intent treatment patients cohort: o lieberkühn adenocarcinoma associated with metastases planned to be treated with peri-operative chemotherapy +/- targeted agent and interval surgery head and neck carcinomas * all cohorts o head and neck squamous cell carcinoma from oral cavity, oropharynx, hypopharynx, larynx * curative intent treatment patients cohort: o planned to be treated with a radical treatment (surgery and/or radiotherapy potentially associated with concurrent chemotherapy) with/without neo-adjuvant/adjuvant chemotherapy. * non-curative intent treatment patients cohort: o de novo metastatic or metastatic/loco-regional relapse planned to be treated with chemotherapy and/or immunotherapy thyroid cancer • curative intent patient cohort o thyroid carcinoma differentiated, poorly differentiated, papillary, vesicular, hurthle cell o for which a iodine treatment is indicated (iodine treatment will be discussed after surgery. in the case the histological result does not confirm a high risk
