简要总结
Evaluate effect on cells and patient response to study medications, assess side effects of these medications, and evaluate chemicals in cells that may tell how the drug works, before, and after receiving the study medications.
详细描述
The purpose of this study is to evaluate the effect on cells and patient response to study medications, assess the side effects of these medications, and to evaluate chemicals in the cells that may tell how the drug works, before, and after receiving the study medications.
Approximately 61 patients will participate at Emory Winship Cancer Institute and Emory Crawford W. Long Hospital in Atlanta, Georgia.

结局指标
主要结局
Dose Escalation and Toxicity: Toxicities Including Grades 1 to 4
时间窗: 12 months from time of enrollment
Participants received a fixed dose of celecoxib 400 mg orally BID continuously for 6 months. Erlotinib was dose escalated at 3 dose levels of 50, 75, and 100 mg orally every day for 6 months. Dose escalation followed a standard 3+3 escalation design.
Clinical Outcome: Documented Progression
时间窗: 12 months from time of enrollment
Response evaluation was based on pathologic examination of the degree of dysplasia observed and recorded by an expert head and neck pathologist. Pathologic complete response was defined as complete disappearance of dysplasia from the epithelium. Pathologic partial response was defined as improvement of dysplasia by at least one degree (i.e., severe dysplasia becomes moderate dysplasia). Pathologic minor response or stable disease was defined as minor focal improvement without change of degree of dysplasia (i.e., focal improvement from moderate to mild dysplasia with still moderate dysplasia overall) or no pathologic changes after treatment. Pathologic progressive disease was defined as worsening by at least one degree of dysplasia (i.e., mild to moderate dysplasia) or development of invasive cancer on or following treatment.
Clinical Outcome: Progression to a Higher-grade Dysplasia or Carcinoma
时间窗: Up to 55 months from initiation of therapy. Median duration of follow-up was 36 months.
