OBJECTIVES:
Primary
Determine the effectiveness of prophylactic cranial radiotherapy in patients with advanced non-small cell lung cancer that is responsive to gefitinib or erlotinib hydrochloride.
Secondary
Determine the progression-free survival in patients treated with this regimen. Determine the overall survival in patients treated with this regimen. Determine the safety and tolerability of this regimen in these patients. Determine the psycho-neurological effects of this regimen in these patients. Determine the quality of life of patients treated with this regimen. OUTLINE: This is a multicenter study. Patients with good response( CR/PR) to EGFR-TKI(Erlotinib or Gefitinib) are randomized to receive EGFR-TKI plus PCI or EGFR-TKI alone,stratified according to prior chemotherapy regimens (first line vs second line), and disease response status.
Group 1: Patients undergo prophylactic brain radiotherapy. Group 2: Patients undergo observation. Patients complete quality of life questionnaires periodically.
After completion of study therapy, patients are followed up periodically.
