Early cancer treatment successes lead to CAREER Award for Rafael Davalos
Date:4/5/2011

In a recent article in the Journal of Clinical Oncology, co-author Rafael Davalos described the use of a method he invented to successfully treat a seven-year old spayed female Labrador retriever with a five-year history of degenerative coxofemoral joint disease. The dog's frequent lameness led to the discovery of a mass that was consistent with a cancerous tumor. With traditional treatment, survival for such a patient is three to six months.

Davalos of the Virginia Tech Wake Forest School of Biomedical Engineering and Sciences http://www.sbes.vt.edu/people/faculty/primary/davalos.html had five collaborators on the article: Robert E. Neal II and Paulo Garcia, also of the biomedical school, along with John H. Rossmeisl, Jr., Otto I. Lanz and Natalia Henao-Guerrero of the Virginia Maryland Regional College of Veterinary Medicine, all at Virginia Tech. http://www.vetmed.vt.edu/

They described how they used a combination of Davalos' patent pending method of irreversible electroporation followed by the well-known medical treatment of chemotherapy to shrink the tumor. After the tumor developed resistance to the chemotherapy, they used irreversible electroporation a second time to completely eradicate all signs of the cancer. After six months, the authors reported in the Feb. 14, 2011 journal article that the family pet was in complete remission according to clinical and computerized tomography scans. http://jco.ascopubs.org/cgi/doi/10.1200/JCO.2010.33.0902

It is now 12 months since the team first treated the patient, and the dog remains in complete remission.

Today, the National Science Foundation has named Davalos as one of its 2011 recipients of a CAREER Award to continue his trailblazing research on the ability of irreversible electropo
