Summary
Brief summary (as posted)
This study will examine tissue specimens from patients participating in a trial of high-dose myo-inositol to prevent lung cancer. The trial, conducted at the British Columbia Cancer Agency-Vancouver Cancer Center (BCCA-VCC), includes people who have pre-cancerous changes in the air passages of their lungs. The BCCA-VCC trial was designed to determine side effects of taking large amounts of the food supplement myo-inositol for longer than a month and if the supplement can help smokers stop smoking. The current study will look at the levels of a substance called Akt in tissue samples obtained from air passages of subjects in the BCCA-VCC trial. Akt is activated by tobacco components and can be found in lung tumor specimens and pre-cancerous lesions. Myo-inositol may affect Akt levels and help prevent progression of pre-cancerous lesions to cancer. People participating in the BCCA-VCC phase 1 myo-inositol trial are eligible for this study. Tissue samples obtained from air passages of these patients during their participation in that study will be sent to the National Cancer Institute for analysis of Akt levels.
