Complete response to erlotinib treatment in brain metastases from recurrent NSCLC

Abstract
In December 2004 she developed progressively worsening pulmonary and neurological symptoms including dizziness. An MRI scan showed cerebral metastases with lesions in the left and right parietal lobes (fig 1A). She was commenced on third line therapy with erlotinib (Roche, 150 mg daily). Within a week of starting treatment her neurological symptoms resolved and her breathlessness improved. An MRI scan taken 6 weeks after starting erlotinib showed a complete response of brain metastases (fig 1B). Six months after starting treatment she remains clinically well on erlotinib without chest related or neurological symptoms except for a grade 1 skin rash.
