Brief Summary:

RATIONALE: Diagnostic procedures, such as positron emission tomography (PET scan) using 11C topotecan, may help doctors predict a patient's response to treatment and help plan the best treatment.

PURPOSE: This phase I/II trial is studying how well a PET scan using 11C topotecan predicts response to treatment in patients with brain metastases due to ovarian, small cell lung, or other cancer.


Condition or disease Intervention/treatment Phase
Lung Cancer Metastatic Cancer Ovarian Cancer Unspecified Adult Solid Tumor, Protocol Specific Procedure: computed tomography Procedure: positron emission tomography Radiation: 11C topotecan Radiation: fludeoxyglucose F 18 Early Phase 1

Detailed Description:

OBJECTIVES:

Primary

  • Determine if tumor uptake of ^11C topotecan occurs quickly enough and at sufficient concentration to be measured immediately following infusion in patients with brain metastases secondary to ovarian cancer, small cell lung cancer, or other cancers.
  • Determine, preliminarily, if ^11C imaging has potential to be an early predictor of response to topotecan therapy in these patients.

Secondary

  • Determine the whole-body biodistribution of ^11C topotecan in these patients.

OUTLINE:

  • Phase I: Patients receive ^11C topotecan IV over 10 minutes followed immediately by a 1-2 hour positron emission tomography (PET) scan. Within 4 weeks after initial imaging, patients also undergo a CT scan.
  • Phase II: Patients receive ^11C topotecan and undergo imaging as in phase I. Patients also receive fludeoxyglucose F 18 IV and, 1 hour later, undergo a PET scan.

PROJECTED ACCRUAL: A total of 10 patients will be accrued for this study.
