RATIONALE: Drugs used in chemotherapy, such as capecitabine, streptozocin, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving capecitabine together with streptozocin is more effective with or without cisplatin in treating neuroendocrine tumors.

PURPOSE: This randomized phase II trial is studying giving capecitabine together with streptozocin to see how well it works compared with or without cisplatin in treating patients with unresectable or metastatic neuroendocrine tumors.

OBJECTIVES:

Primary

* To determine the objective response rate in patients with neuroendocrine tumors treated with capecitabine and streptozocin with or without cisplatin.

Secondary

* To determine the overall response rate, including both objective and biochemical responses, to these regimens.
* To determine the functional response to these regimens.
* To determine the toxicity of these regimens.
* To identify the optimal drug doses in each regimen to be recommended for a subsequent phase III trial.
* To determine the progression-free and overall survival of patients receiving these regimens.
* To determine the quality of life of these patients.
* To determine molecular markers predictive of response to chemotherapy.

OUTLINE: This is a multicenter study. Patients are stratified according to site of origin (known vs unknown primary site), prior antitumor treatment, tumor function (functional vs nonfunctional), and study center. Patients are randomized to 1 of 2 treatment arms.

* Arm I: Patients receive streptozocin IV over 2 hours on day 1 and oral capecitabine twice daily on days 1-21.
* Arm II: Patients receive cisplatin IV over 2 hours on day 1 and streptozocin and capecitabine as in arm I.

In both treatment arms, treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Patients complete the EORTC QLQC30 questionnaire and EORTC QLQ-GI.NET21 module for quality-of-life assessment at baseline, every 9 weeks during treatment, and at 12 weeks post-treatment.

Tumor tissue is obtained at baseline and assessed for Ki67 and mitotic index. Novel tissue-specific transcription factors (e.g., CDX2) are also assessed. Blood samples are collected at baseline and 9 weeks and examined by DNA, RNA, and proteomic analysis.

After completion of study therapy, patients are followed every 12 weeks.
