- Toxicity [ Time Frame: 30 DAYS ]Number of participants with acute and late toxicity
- Clinical Response [ Time Frame: 20 months ]Response to Concurrent Erlotinib, Celecoxib, and Reirradiation according to Response Evaluation Criteria in Solid Tumors - Complete Response (CR): Disappearance of all target lesions Partial Response (PR): At least a 30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD Progressive Disease (PD): At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions
- Locoregional Progression [ Time Frame: 20 months ]Patients with locoregional and/or distant progression
- Locoregional Control, Progression-free Survival, Overall Survival and Late Toxicity [ Time Frame: 1 year ]At a median follow-up of 11 months, the 1 year locoregional control, progression-free survival, and overall survival rates.

In this phase I/II study, patients will be treated with daily erlotinib 150 mg and twice-daily celecoxib 200 to 600 mg for 14 days. Re-irradiation with IMRT will start on day 15 and will continue for 5.5 to 6.5 weeks along with erlotinib and celecoxib. After completion of radiation, patients will be given the option of continuing on erlotinib for 2 years or until unacceptable toxicity or disease progression
Despite advances in the treatment of head and neck cancer, locoregional recurrences are the predominant site of treatment failure and are frequently the cause of death. Second primary tumors in the head and neck occur in up to 30% of patients at 10 years of follow-up after eradication of the original tumor due to field cancerization. The standard approach to patients with recurrent but non-metastatic disease has been surgical salvage alone. Unfortunately, this strategy is feasible in only a select group of patients and 5 year survival rates have ranged from 15-40%.
Most patients with previously irradiated unresectable recurrent or metastatic head and neck cancer are treated with chemotherapy alone. This approach has offered limited palliation with response rates of 10-40%, median survival of 5 to 10 months. While this may be an acceptable option for patients with clearly incurable widespread metastatic disease, it may not be the best approach for those patients with potentially curable locoregional disease.
While geographic misses and second primary tumors occur, the majority of patients have radioresistant tumors. Therefore, reirradiation alone is unlikely to be effective. High dose reirradiation with concomitant chemotherapy represents a more aggressive approach resulted in encouraging 3-year survival rates of 15 to 35%. This approach represents a potentially curative option for patients with unresectable or partially resected disease arising in a previously irradiated volume. However, the high rates of acute and late toxicity with this approach have limited widespread application of this approach.
Extensive preclinical and clinical data suggest that both epidermal growth factor receptor (EGFR) antagonists and cyclooxygenase-2 (COX-2) inhibitors enhance the effectiveness of ionizing radiation. In locally advanced head and neck cancer, a recent phase III trial concurrent anti-EGFR monoclonal antibody and radiation demonstrated improved local control, disease free survival and overall survival compared to radiation alone without the increased mucosal toxicity associated with concurrent chemotherapy. COX-2 inhibition and anti-EGFR therapy demonstrates activity against recurrent/metastatic head and neck cancer in a recent phase I study. Head and neck cancer represents an ideal site to study biologic markers of tumor response because of the accessibility of tumors for biopsy. Therefore, we propose the combination of Erlotinib and Celecoxib with radiation in a cohort of previously irradiation patients with head and neck cancer.
