Ratio of Positron Emission Tomography Uptake to Tumor Size in Surgically Resected Non-Small Cell Lung Cancer

The ratio of SUVmax to tumor size may be a more important indicator of prognosis than SUVmax alone in patients with NSCLC. In particular, the use of the ratio may be appropriate for identifying patients with small tumors who are at high risk for lymph node metastases and poor survival.
