New Positron Emission Tomography (PET) Biomarker NVB-64 Visualizes Malignant Breast Tumors
Date:10/29/2009

kly became the preferred method of breast cancer detection. Not until 2004 was the first non-surgical procedure looking towards breast cancer detection using Positron Emission Tomography (PET) with 18fluorodeoxyglucose (FDG) approved for use in patients. FDG-PET has two significant drawbacks: 1) FDG-PET leaves a frustrating 30% of tumors undetected; and 2) FDG cannot reliably distinguish between benign and malignant tumors.

The significant advance of NVB-64 is the recognition of genetic changes at the cellular level, as a genomic biomarker, rather than the overly generalized metabolic markers found with FDG.

Nearly as important as the human implications are the enormous financial ramifications. Lead investigator Mathew Thakur Ph.D. Professor of Radiology and Director of the Laboratories of Radiopharmaceutical Research and Molecular Imaging at Thomas Jefferson University Hospital says, "The use of NVB64-PET scan in the future may minimize the need for unnecessary biopsy of benign tumors." Currently, nearly 6 million such biopsies are performed annually in the United States, at an estimated annual cost of $30 billion. Approximately 80% or 4.8 million biopsies, demonstrate benign pathology.

The biomarkers NuView has in development can, with alteration of the radionuclide attached to the compound, change them from a diagnostic to a targeted therapy, or a pairing of a target specific diagnostic and therapy. NuView Medical Director Peter S. Conti, MD, PhD adds, "Development of targeted diagnostics that can be modified to also carry therapeutic isotopes can lead to unique agents that can broaden the range of therapies available for cancer patients."

Anticipated Benefits of NVB-64:

  • Same day, immediate confirmation of the patient having either benign or malignant breast tumor(s).
  • Choice of care in selecting a screening method to determine the malignant or benign status of a mass found on a mammogram.'/>"/>
