Lead Sponsor
University Hospital, Clermont-Ferrand
Brief Summary

Exploratory interventional study of prognostic serum biomarkers of cancer progression.

Study of the relationship between the blood levels of soluble PDL1 and β2-microglobulin, and the clinical course of a metastatic solid tumor treated with a first-line therapeutic of checkpoint immune inhibitor.

Detailed Description

Primary objective To study the relationship between the blood levels of soluble PDL1 and β2-microglobulin measured at the diagnostic stage, and the clinical course of a metastatic solid tumor (non-small cell lung cancer, kidney cancer, or melanoma) treated with a 1st line therapeutic immune checkpoint inhibitor.

The secondary objectives are:

* To study the relationship between the blood levels of soluble PDL1 and β2-microglobulin measured during treatment, and the clinical course of a metastatic solid tumor treated with a first-line therapeutic immune checkpoint inhibitor.

* To study the correlation between the soluble PDL1 level and the tumor PDL1 level.

* To study the correlation between the blood levels of soluble PDL1 and β2-microglobulin.

* To study the relationship between the blood levels of soluble PDL1 and β2-microglobulin measured during the treatment, and the tolerance of treatment with immune checkpoint inhibitor in 1st line therapy.

Metastatic solid tumor treated with first line therapeutic of Immune Checkpoint InhibitorBlood sample* The determinations of soluble PDL1 and serum B2M will be taken by blood sample at diagnosis and then every 3 months for 1 year, during a consultation or treatment in an outpatient hospital. * The measurement of the tumor PDL1 level at diagnosis will be carried out by immunohistochemistry in the anatomopathology department of Clermont Ferrand University Hospital on the tumor sample that allowed the diagnosis, which does not add an additional sample for the patient. * Clinical and imaging examinations will be those conventionally carried out in the context of patient monitoring, the data will only be recorded in the patients' medical files.
