                         We are on the threshold of expanded use of onycolytic viruses for a number of 

malignancies including malignant melanoma. An oncolytic virus is a virus that preferentially

infects and kills tumor cells.

                        The drug Talimogene laherparepvec (TVEC) is a type one herpes simplex virus

(HSB) genetically modified to preferentially replicate in the tumor cells of malignant melanoma.

                        As the infected cancer cells are destroyed by the virus,,the virus releases new

infectious virus particles called virions to help destroy the remaining tumor.

                       Oncolytic viruses are thought not only to cause direct destruction of the tumor

cells,but also to stimulate host antitumor immune responses.

                      In addition,researchers are now using a modified poliovirus to unleash the

body's ability to fight cancer.

                     Also,these cancer killing viruses may be utilized for a number of malignancies 

including a type of brain cancer called glioblastoma,a blood cancer called multiple myeloma,

a cancer of the lining of the lung cavity called mesothelioma,and carcinomas of the breast,

lung,prostate,kidney,liver,pancreas,bladder,ovary and head and neck.

                  Only time and additional research will tell if these oncolytic viruses will

increase cancer patient survival  time or cure rates.
