Conditions

Advanced Solid Tumor, Non Small Cell Lung Cancer

Keywords

non-small cell lung cancer, EGFR detection, liquid biopsy

Brief summary

Multicenter prospective cohort study aiming to evaluate the detection rate of EGFR gene mutation in patients with advanced NSCLC in a real-word clinical setting, based on liquid biopsy and tissue analyses.

Detailed description

This a multicenter prospective cohort study. This study will be proposed to newly diagnosed advanced NSCLC patients. For included patients, archived paraffin embedded tumor tissue will be used for sequencing ; and blood sample will be collected for research purpose (plasma DNA collection and sequencing). Both tissue and liquid biopsy samples will follow usual processes and will be sent to the Molecular Pathology laboratory of the Investigation center.

Interventions

Intervention model description

This is a multicentric prospective cohort in which newly diagnosed advanced NSCLC patients will be included. For all patients, both tumor and liquid biopsy samples will be used for sequencing and detection of EGFR gene mutation

Design outcomes

Primary

MeasureTime frameDescription
To assess the detection rate of patients with an EGFR actionable alteration when using the combination of two diagnostic procedures which include liquid biopsy analysis (by droplet digital PCR or allele specific PCR) and tissue analysiswithin 3 weeks after signature of informed consentResuls of each EGFR diagnostic procedure will be categorized as EGFR positive in case of the presence of an EGFR actionnable alteration ; as EGFR negative in case of the absence of an EGFR actionnable alteration ; or nor interpretable. A patient will be considered to have an EGFR actionable alteration if the mutation has been detected on the sequencing of tumor tissue OR if it has been detected on the liquid biopsy procedure

Secondary

MeasureTime frameDescription
The detection rate of patients with an EGFR actionable alteration based on the use of liquid biopsy analysis onlywithin 3 weeks after signature of informed consentA patient will be considered to have an EGFR actionable alteration (EGFR+) detected by the liquid biopsy analysis if an EGFR actionable alteration is identified based on the liquid biopsy analysis
The detection rate of patients with an EGFR actionable alteration based on tissue analysis onlywithin 3 weeks after signature of informed consentA patient will be considered to have an EGFR actionable alteration (EGFR+) detected by tissue analysis if an EGFR actionable alteration is identified based on the sequencing of tumor tissue
The concordance and discordance rates between the two procedureswithin 3 weeks after signature of informed consentConcordance is defined whenever results of both techniques are identical (i.e. EGFR+ for both techniques or EGFR- for both techniques). Discordance is defined whenever results of both techniques are different.
The failure rate for each procedure and reasons of failure (insufficient DNA quantity, poor DNA quality, insufficient tissue quantity, poor tissue quality, analytical failure)within 3 weeks after signature of informed consent• Failure of a procedure (sequencing of tumor tissue or liquid biopsy) is defined whenever the procedure fails to provide an interpretable result (Reasons for failure will be collected, i.e. insufficient DNA quantity, poor DNA quality, insufficient DNA/tissue quantity, poor DNA/tissue quality, analytical failure)
Delay to obtain sequencing resultswithin 3 weeks after signature of informed consentThe delay between the date of the signature of the informed consent and the date of availability of the results for each procedure
Delay for treatment initiationwithin 3 months after signature of informed consentThe delay between the date of sample collection and the date of treatment initiation
