BACKGROUND While genetically engineered viruses are now being tested for the virus therapy of human cancers, some naturally occurring viruses display unmatched oncolytic activity. Newcastle disease virus (NDV) excels as an oncolytic agent. OBJECTIVES As its virulence versus attenuation can be explained on molecular biological bases, it may be possible to(More)
Classical and molecular immunological means of active tumor-specific immunization against human cancers yielded whole cell or tumor cell lysate vaccines of preventive value (reduced relapse rates) and dendritic cell-peptide or genetically engineered vaccines that may induce remissions even in metastatic disease. Active tumor-specific immunization was often(More)
The senior author of this comprehensive review observed and reported in 1969 that his lymphocytes killed allogeneic tumor cells in vitro. Some of his research associates and technicians and other healthy individuals also yielded such killer lymphocytes. The team considered pre-immunization to cancer occurring in individuals after in-family or professional(More)
DTIC was one of the first of several new agents evaluated by the Southwest Oncology Group (SWOG) and the M.D. Anderson Hospital and Tumor Institute (MDAH) in the therapy of adult patients with metastatic sarcomas. It yielded an overall response rate of 17%. This is similar to that seen in a review of 138 patients who represent the total number reported in(More)
Based on personal acquaintances and experience dating back to the early 1950s, the senior author reviews the history of viral therapy of cancer. He points out the difficulties encountered in the treatment of human cancers, as opposed by the highly successful viral therapy of experimentally maintained tumors in laboratory animals, especially that of ascites(More)
In the early 1970s supervised clinical trials were initiated at The University of Texas M.D. Anderson Hospital in Houston, TX, for the combination of viral oncolysate-based vaccines and contemporary chemotherapy for the treatment of patients with metastatic melanoma and sarcomas. This therapeutic approach was then generally considered to be inappropriate(More)
Direct virus inoculations and viral oncolysates may induce temporary remissions and prolong life with reduced tumor burden, or decrease relapse rates but fall short of curing human cancers. We propose: (i) investigations of Cassel's 73-T, an Ehrlich's mouse ascites carcinoma-adapted Newcastle disease virus (NDV) strain that so effectively reduced relapse(More)
