Brief summary:
PURPOSE: Phase II trial to study the effectiveness of combining capecitabine and irinotecan in treating patients who have locally advanced, recurrent, or metastatic colorectal cancer.

Detailed description:
OBJECTIVES:

Primary:

* Determine the overall objective response rate in patients with locally advanced, locally recurrent, or metastatic colorectal cancer treated with capecitabine and irinotecan.

Secondary:

* Determine the time to treatment failure, time to overall response, duration of overall response, duration of overall complete response, and time to progression in patients treated with this regimen.
* Determine the 1-year survival and overall survival of patients treated with this regimen.
* Determine the toxicity and safety profile of this regimen in these patients.
* Determine the feasibility of predicting responses to this regimen by the molecular profile of tumor tissue in patients treated with this regimen.

OUTLINE: This is a multicenter study.

Patients receive oral capecitabine twice daily on days 2-15 and irinotecan IV over 90 minutes on days 1 and 8. Treatment repeats every 3 weeks for 12 courses in the absence of disease progression or unacceptable toxicity. Patients maintaining a response or stable disease after 12 courses may continue treatment at the discretion of the investigator.

Patients are followed every 3 months.

PROJECTED ACCRUAL: A total of 65 patients will be accrued for this study within 9 months.

Arms:
arm 1: Participants will receive capecitabine (Xeloda) 1000 mg/m\^2, orally, twice daily, for 14 days (Day 2 through Day 15) every 3 weeks, along with irinotecan 125 mg/m\^2 as a 90-minute intravenous (IV) infusion on Day 1 and Day 8, every 3 weeks. A total of 12 cycles of treatment will be administered. At the discretion of the investigator, participants who are responding or whose disease is stable will be permitted to continue capecitabine/irinotecan combination therapy until progressive disease is documented in the post-study treatment phase. Participants not participating in post-study treatment will be followed every 3 months until time of death, loss to follow-up, or until median survival had been reached (whichever occurred first). arm 2: Participants will receive capecitabine 900 mg/m\^2, orally, twice daily, for 14 days (Day 2 through Day 15) every 3 weeks, along with irinotecan 100 mg/m\^2 as a 90-minute intravenous (IV) infusion on Day 1 and Day 8, every 3 weeks. A total of 12 cycles of treatment will be administered. At the discretion of the investigator, participants who will be responding or whose disease is stable will be permitted to continue capecitabine/irinotecan combination therapy until progressive disease is documented in the post-study treatment phase. Participants not participating in post-study treatment will be followed every 3 months until time of death, loss to follow-up, or until median survival had been reached (whichever occurred first).
