Dutch researchers conducted pre-treatment imaging with FDG-PET/CT, HX4-PET/CT and dynamic contrast-enhanced CT in patients with non-small cell lung cancer and found that those whose supervoxel tumor segments had intermediate perfusion values and the highest HX4 and FDG standardized uptake values had significantly worse two-year survival, compared with those with different tumor supervoxel characteristics. An image analysis framework developed based on the findings, which were published in the journal Radiotherapy and Oncology, enabled proper categorization of all tumors and may help in classifying tumor hypoxias and stratifying patients, researchers said.
