Glucose Metabolism in Patients With Non-Small Cell Lung Cancer Treated With Targeted Therapy and Chemotherapy

Monitoring Targeted Lung Cancer Treatments With FDG-PET/CT

RATIONALE: Measuring changes in glucose metabolism in patients with cancer may help doctors predict how patients respond to treatment.

PURPOSE: This clinical trial is studying glucose metabolism in patients with non-small cell lung cancer treated with targeted therapy and chemotherapy.

OBJECTIVES:

• Determine the prognostic significance of changes in glucose metabolism measured by fludeoxyglucose F 18 positron emission tomography (FDG-PET)/CT scan in patients with non-small cell lung cancer treated with targeted drugs comprising gefitinib, erlotinib hydrochloride, or other ErbB inhibitors, cyclooxygenase-2 inhibitors, or estrogen receptor blockers in combination with conventional chemotherapy.

OUTLINE: This is a prospective study.

Patients undergo fludeoxyglucose F 18 positron emission tomography (FDG-PET) scan and CT scan at baseline and at 2 weeks and 12 weeks after receiving targeted anticancer treatment. Metabolic changes detected by FDG-PET and size changes identified by CT scan are related to patient outcome and tumor response to treatment.

PROJECTED ACCRUAL: A total of 120 patients will be accrued for this study.

Inclusion Criteria:

• Histologically or cytologically confirmed non-small cell lung cancer
• Any disease stage allowed
• Undergoing targeted treatment

Exclusion Criteria:

None
