Experimental: Treatment (erlotinib hydrochloride)
Patients receive oral erlotinib once daily. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. Patients with a CR receive 2 additional courses after CR is confirmed.

I. Determine the efficacy of erlotinib, in terms of response rate and duration of stable disease, in patients with recurrent or metastatic colorectal cancer.
II. Determine the toxicity of this drug in these patients. III. Determine the time to progression and response duration in patients treated with this drug.
IV. Determine the relationships between clinical, pharmacokinetic, and pharmacodynamic effects of this drug in these patients.
V. Correlate baseline and post-treatment levels of epidermal growth factor receptor, its downstream signaling components, markers of angiogenesis, and apoptosis in tumor and skin biopsies with clinical outcome in patients treated with this drug.
OUTLINE: This is a multicenter study.
Patients receive oral erlotinib once daily. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. Patients with a complete response (CR) receive 2 additional courses after CR is confirmed.
Patients are followed every 8 weeks.
PROJECTED ACCRUAL: A total of 15-30 patients will be accrued for this study within 4-8 months.
