Clinical trial: High-Dose or Standard-Dose Radiation Therapy and Chemotherapy With or Without Cetuximab in Treating Patients With Newly Diagnosed Stage III Non-Small Cell Lung Cancer That Cannot Be Removed by Surgery

Summary: RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as paclitaxel, carboplatin work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether high-dose radiation therapy is more effective than standard-dose radiation therapy when given together with combination chemotherapy with or without cetuximab in treating patients with non-small cell lung cancer.
  PURPOSE: This randomized phase III trial is studying high-dose or standard-dose radiation therapy given together with chemotherapy with or without cetuximab to see how well they work in treating patients with newly diagnosed stage III non-small cell lung cancer that cannot be removed by surgery.

Detailed description: OBJECTIVES:
  Primary
  -  To compare the overall survival of patients with newly diagnosed, unresectable stage IIIA or IIIB non-small cell lung cancer treated with high- versus standard-dose conformal radiotherapy with concurrent and consolidation chemotherapy comprising carboplatin and paclitaxel.
  -  To compare the overall survival of patients treated with versus without cetuximab in the setting of concurrent chemotherapy
  Secondary
  -  To compare progression-free survival and local-regional tumor control in patients treated with these regimens.
  -  To compare the toxicity of high- versus standard-dose conformal radiotherapy and concurrent chemotherapy with versus without cetuximab in these patients.
  -  To investigate the prognostic and predictive effects of gross tumor volume on overall survival of patients treated with these regimens.
  -  To compare the quality of life of patients treated with these regimens.
  -  To correlate outcomes (i.e., survival, toxicity, or QOL) in these patients with biological parameters.
  -  To analyze the predictive value of pre-treatment standardized uptake value (SUV) of PET scan in predicting survival, distant metastasis, and local-regional control in patients treated with these regimens.
  -  To explore biological markers to predict clinical outcome including survival, distant metastasis, local-regional control, and QOL (including toxicity) in patients treated with these regimens.
  -  To prospectively collect and bank tissue, blood, and urine specimens for future biomarker analyses in predicting clinical outcome in patients treated with these regimens.
  -  To investigate associations between epidermal growth factor receptor (EGFR) expression and toxicity, response, overall survival, and progression-free survival.
  OUTLINE: This is a multicenter study. Patients are stratified according to PET staging (yes vs no), radiotherapy technique (3-dimensional conformal radiotherapy vs intensity-modulated radiotherapy), Zubrod performance status (0 vs 1), 4-dimensional CT planning utilization (yes vs no), and histology (squamous vs non-squamous). Patients are randomized to 1 of 4 treatment arms. (Arms II and IV closed to accrual effective 6/17/11)
  -  Arm I: Patients undergo standard dose radiotherapy 5 days a week for 6 weeks for a total of 60 Gy. Patients receive concurrent chemotherapy comprising paclitaxel IV over 1 hour and carboplatin IV over 30 minutes on days 1, 8, 15, 22, 29, and 36. Patients also receive consolidation treatment of paclitaxel and carboplatin on days 64 and 85. Treatment repeats in the absence of disease progression or unacceptable toxicity.
  -  Arm II: Patients undergo high-dose radiotherapy 5 days per week for 7.5 weeks. Patient also receive concurrent paclitaxel and carboplatin as in Arm I on days 1, 8, 15, 22, 29, 36, and 43 . Patients also receive consolidation treatment comprising paclitaxel and carboplatin on days 71 and 92. (closed to accrual effective 6/17/11)
  -  Arm III: Patients undergo standard-dose radiotherapy 5 days a week for 6 weeks for a total of 60 Gy. Patients receive cetuximab in addition to concurrent chemotherapy as in Arm I. Treatment continues with chemoradiation and cetuximab on days 8, 15, 22, 29, 36, and 43. Patients receive consolidation treatment of cetuximab on days 50, 57, 64, 71, 78, 85, 92, 99, and 106 and paclitaxel and carboplatin on days 71 and 92.
  -  Arm IV: Patients undergo high-dose radiotherapy 5 days a week for 7.5 weeks for a total of 74 Gy. Patients receive cetuximab in addition to concurrent chemotherapy as in Arm I. Treatment continues with chemoradiation and cetuximab on days 8, 15, 22, 29, 36, 43, and 50. Patients receive consolidation treatment of cetuximab on days 57, 64, 71, 78, 85, 92, 99, 106, and 113 and paclitaxel and carboplatin on days 78 and 99. (closed to accrual effective 6/17/11) Patients may undergo tumor tissue, blood, and urine collection periodically during study for tissue banking or biomarker correlative studies.
  Patients may undergo quality-of-life assessment at baseline and periodically during study.
  After completion of study therapy, patients are followed periodically for 5 years and then annually thereafter.
