Study Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving a chemotherapy drug before surgery may shrink the tumor so that it can be removed during surgery. PURPOSE: Phase II trial to study the effectiveness of O6-benzylguanine followed by surgery in treating patients who have solid tumors that can be removed during surgery.

Primary Outcome

Determine minimal dose of 06-benzylguanine (06-BG) at which there is a depletion of tumor 06-BG DNA alkyltransferase activity to \<10 fmol/mg protein
