Noninvasive Measurement Enables Use of IFP as Potential Biomarker for Tumor Aggressiveness, Institute for Cancer Research Study

Researchers validated a method of noninvasive imaging that provides valuable information about interstitial fluid pressure of solid tumors and may aid in the identification of aggressive tumors, according to the results of a study published in Cancer Research, a journal of the American Association for Cancer Research. Many malignant solid tumors generally develop a higher interstitial fluid pressure (IFP) than normal tissue. High IFP in tumors may cause a reduced uptake of chemotherapeutic agents and resistance to radiation therapy. In addition, a high IFP has been found to promote metastatic spread.
