Brief summary: RATIONALE: Biological therapies such as ZD 1839 may interfere with the growth of tumor cells and slow the growth of colorectal cancer.

PURPOSE: Phase II trial to study the effectiveness of ZD 1839 in treating patients who have locally advanced or metastatic colorectal cancer that has not responded to chemotherapy.

Detailed description: OBJECTIVES:

* Determine the progression-free rate at 16 weeks, response rate, time to treatment failure, and survival of patients treated with gefitinib for locally advanced or metastatic colorectal adenocarcinoma that is refractory to fluorouracil, irinotecan, and capecitabine.
* Correlate the pharmacodynamic effects of this drug with indices of clinical benefit (e.g., tumor growth inhibition, time to tumor progression, and survival) in these patients.
* Determine whether the status of epidermal growth factor receptor activation and signaling are predictive of clinical outcome in patients treated with this drug.

OUTLINE: This is a multicenter study.

Patients receive oral gefitinib once daily. Treatment continues every 28 days in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 18-46 patients will be accrued for this study within 5-12 months.

Eligibility criteria: DISEASE CHARACTERISTICS:

* Histologically or cytologically confirmed colorectal adenocarcinoma

  * Metastatic or locally advanced disease
  * Not amenable to curative therapy
* Documentation of disease progression within the past 6 months
* Previously treated with fluoropyrimidine- and irinotecan-based chemotherapy (including capecitabine) administered either concurrently (no more than 2 regimens) or sequentially (no more than 3 regimens) for advanced disease
* At least 1 unidimensionally measurable lesion

  * At least 20 mm by conventional techniques OR at least 10 mm by spiral CT scan
* No known brain metastases

PATIENT CHARACTERISTICS:

* Platelet count at least 100,000/mm\^3

Hepatic:

* Bilirubin no greater than 1.5 times upper limit of normal (ULN)
* AST/ALT no greater than 3 times ULN (5 times ULN if liver metastasis present)

Renal:

* No other uncontrolled concurrent illness
* No ongoing or active infection
* No psychiatric illness or social situation that would preclude study participation
* No prior gastrointestinal disorders (e.g., malabsorption syndrome)
* No prior allergic reactions attributed to compounds of similar chemical or biological composition to gefitinib
* No other prior malignancy except carcinoma in situ of the cervix, nonmelanoma skin cancer, or other cancer from which the patient has been free of evident disease for more than 5 years and/or has less than a 20-30% estimated likelihood of recurrence
* Not pregnant or nursing
* Negative pregnancy test
* Fertile patients must use effective contraception
