Metastatic Non-small Cell Lung Cancer

Brief summary

In patients with locally advanced or metastatic tumors, first-line therapeutic management is based on the use of targeted therapies (EGFR, BRAF ALK and ROS1 inhibitors), immunotherapies (anti-PD1/ anti-PDL1-antibodies or chemotherapy. Despite patient selection based on histo-pathological and molecular criteria, not all patients respond to treatment. There are currently no markers to definitively guarantee a patient's response. An alternative is to identify early patient response to treatment. The investigator hypothesize that change in circulating tumor DNA concentration (ctDNA) allow to early identify patients' therapeutic response (and non-response) of patients, regardless of the type of treatment used in the first line setting.

Detailed description

The primary objective is to determine whether early evolution (between baseline and week 3) of circulating tumor DNA concentration predicts the radiological response to first-line treatment of advanced or metastatic NSCLC patients, regardless of treatment

Design outcomes

Primary

MeasureTime frameDescription
Biological response at week 3week 3 after patient's recruitment date (baseline)Changes of the amount of ctDNA between baseline and week 3 will make it possible to determine the biological response: increase, stability or decrease in ctDNA.

Secondary

MeasureTime frameDescription
Progression-free survival (radiological assessment) and biological response at week 3.week 3 after baselineRadiological assessment, based on Response Evaluation Criteria in Solid Tumors (RECIST) criteria v1.1, will be: complete response, partial response, progression or stabilization. Biological response will be: increase, stability or decrease in ctDNA.
biological progression and radiological progressionprogressionBiological progression will be: increase in ctDNA - Radiological progression will be defined according to RECIST criteria v1.1 will be: progression
biological response and radiological responseprogressionBiological response will be: increase, stability or decrease in ctDNA and Radiological response will be defined according to RECIST criteria v1.1 will be: complete or partial response
Biological response and progression-free survival (radiological assessment) according to the therapeutic management: targeted therapies, immunotherapy, chemotherapyweek 3 after baselineRadiological assessment, based on RECIST criteria v1.1, will be: complete response or partial response. Biological response will be: increase, stability or decrease in ctDNA.
