Assay for the detection of Taxol-resistant cells in human tumors

Summary:
As with most cancer chemotherapeutic drugs, the sensitivity of cancer patients to taxane therapy decreases over a period of time that is shorter than the life of the disease.  Thus, a simple assay to assess a patient's sensitivity to taxanes would diminish the time during which limited or no chemotherapeutic benefits are achieved from taxane administration.  The UTHSCH has developed such an assay, the implementation of which will allow clinicians to screen cancer patients, prior to and during taxane administration, to monitor their patients’ taxane-sensitivity and to allow the most timely administration of alternative therapy when taxane-resistance is detected.  This UTHSCH-owned technology describes the development and utility of a diagnostic assay with sufficient sensitivity to assess Taxol-resistant cells in tumor biopsies or extracted nucleic acids.  This taxane-resistance detection technology will be of great value to patients, physicians and the corporate licensee.
