The virus displayed inherently high selectivity for cancer cells, sparing normal cells both in vitro and in vivo, with effective infection of tumors after both intravenous (i.v.) and intratumoral (i.t.) administrations. The Lister vaccine strain of vaccinia virus was effective against all human pancreatic carcinoma cells tested in vitro, especially those insensitive to oncolytic adenovirus.


In this study, we have evaluated the effectiveness of the Lister vaccine strain of vaccinia virus armed with the endostatin–angiostatin fusion gene (VVhEA) as a novel therapeutic approach for pancreatic cancer. Oncolytic virotherapy is an attractive approach for cancer treatment.

Survival after pancreatic cancer remains poor despite incremental advances in surgical and adjuvant therapy, and new strategies for treatment are needed.
