Intérêt de l'ADN tumoral circulant dans le cancer pulmonaire : à propos d'un cas

Circulating DNA analysis allows the identification of activating mutations of the EGFR gene in pulmonary adenocarcinomas. It is useful for weakened patients and in case of failure or inability of tumor biopsies. Initiation of EGFR TKI is possible on the basis of this result, as stated in the marketing authorization of gefitinib.
