There have been conflicting reports on the continuation of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) in patients with newly developed or progressive brain metastasis of non-small cell lung cancer (NSCLC). Patients with newly developed or progressive intracranial lesions, but who maintained well-controlled extracranial disease during erlotinib treatment, were enrolled in this study. The proposed therapy included stereotactic radiosurgery (SRS), whole brain radiotherapy (WBRT), and/or surgical resection for intracranial lesions. Erlotinib treatment was continued simultaneously unless extracranial disease progressed. The evaluation of both extra- and intra-cranial lesions was performed every 3 months. From October 2009 to June 2012, 14 patients were enrolled in this pilot study. For intracranial disease, 4 patients received SRS alone, 7 patients received both SRS and WBRT, 2 patients received SRS, WBRT and surgical resection, and 1 patient received no local therapy due to the presence of asymptomatic lesions. Of the patients with extracranial disease who were placed on continued erlotinib therapy, 6 patients (42.9%) showed partial response (PR), while 7 patients (50.0%) remained in stable disease (SD). The progression-free survival (PFS) of extracranial and intracranial disease was 11.1 (range 1.6-34.6) and 10.2 (range 1.5-34.6) months, respectively. In 5 cases, brain lesions relapsed before the progression of extracranial disease. Overall survival (OS) was 22.6 (range 2.1-50.4) months. For NSCLC patients with progression of only intracranial disease during erlotinib treatment, the continuation of erlotinib in combination with local therapy to brain metastases can be an effective treatment option.
