Brief summary: RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of temozolomide in treating patients who have unresectable or metastatic gastrointestinal stromal tumors.

Detailed description: OBJECTIVES:

* Determine the complete and partial response (confirmed and unconfirmed) in patients with unresectable or metastatic gastrointestinal stromal tumors treated with temozolomide.
* Determine the qualitative or quantitative toxic effects of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients receive oral temozolomide once daily on days 1-5. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity. Patients achieving a confirmed complete response (CR) receive 2 additional courses after a confirmed CR.

Patients are followed every 3 months for 1 year and then every 6 months for 2 years.

PROJECTED ACCRUAL: A total of 20-40 patients will be accrued for this study within 13-27 months.

* At least 1 measurable lesion by x-ray, CT, MRI, ultrasound, or physical examination

  * If lesions within prior radiation port are used as target lesions for response assessment, those lesions must have demonstrated clear progression after completion of radiotherapy
* No uterine or retroperitoneal sarcomas or non-intra-abdominal leiomyosarcomas
