Cervico-thoracic CT scan showing response to erlotinib. Three different dates of treatment are shown: July 2009 (on imatinib), February 2010 (progression on imatinib; just before erlotinib), and September 2010: (response after 7 months of erlotinib). Two targets lesions are shown (arrows): the right pectoral lesion (A), and the right cervical adenopathy (B): both progressed between July 2009 and February 2010 during imatinib treatment, and responded to erlotinib between February and September 2010: regression in size of the pectoral lesion (A), and disappearance of the peripheral contrast enhancement for the adenopathy (B).
