PET/CT tumor volume best predicts breast cancer survival

July 30, 2015

Whole-body metabolic tumor volume, as determined by FDG-PET/CT before treatment, is a reliable prognosticator of overall survival in patients who have invasive ductal carcinoma (IDC) of the breast and distant metastases at the time of their initial diagnosis, according to a study published online July 23 in theAmerican Journal of Roentgenology.

The researchers from Korea also found that determining the maximum standardized uptake value (SUVmax) of whole malignant lesions and whole-body total lesion glycolysis are useful in predicting overall survival for these patients.
