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.
OBJECTIVES: I. Determine the minimal O6-benzylguanine (O6-BG) dose required to deplete tumor activity to less than 10 fmol/mg protein at a specified time after administration in patients with surgically resectable solid tumors. II. Correlate tumor tissue AGT depletion with AGT depletion in peripheral blood mononuclear cells (PBMC) obtained at a specified time after O6-BG administration in these patients.
OUTLINE: This is a dose escalation study. Patients receive a single dose of O6-benzylguanine (O6-BG) IV over 1 hour at one of two dose levels. Patients undergo surgery 16-20 hours after administration of O6-BG. Up to 13 patients receive the lower dose level of O6-BG. If more than 3 patients have detectable AGT levels, additional patients receive the higher dose. The optimal biologic dose (OBD) is defined as the lowest dose level at which at least 11 of 13 patients have AGT activity less than 10 fmol/mg protein after O6-BG dosing. Patients are followed at 1 and 3 weeks post surgery.
PROJECTED ACCRUAL: A total of 13-26 patients will be accrued for this study over approximately 10 months.

A solid, unencapsulated tumor of the KIDNEY composed of spindle mesenchymal cells that resemble FIBROBLASTS or muscle cells. The homogeneous mass typically extends into the renal parenchyma and replaces most of the kidney. In most cases, mesoblastic nephroma is benign and occurs in the fetus or newborn, and rarely in the older child or the adult.
A transplantable, poorly differentiated malignant tumor which appeared originally as a spontaneous breast carcinoma in a mouse. It grows in both solid and ascitic forms.
A malignant cystic or semisolid tumor most often occurring in the ovary. Rarely, one is solid. This tumor may develop from a mucinous cystadenoma, or it may be malignant at the onset. The cysts are lined with tall columnar epithelial cells; in others, the epithelium consists of many layers of cells that have lost normal structure entirely. In the more undifferentiated tumors, one may see sheets and nests of tumor cells that have very little resemblance to the parent structure. (Hughes, Obstetric-Gynecologic Terminology, 1972, p184)
