Abstract Solid tumours account for 90 of all cancers. Gene therapy represents a potential new modality for their treatment. Up to now several approaches have been developed but the most efficient ones are the viral vector based gene therapy systems. However viral vectors suffer from several deficiencies firstly most vectors currently in use require intratumoural injection to elicit an effect. This is far from ideal as many tumours are inaccessible and many may have already spread to other parts of the body making them difficult to locate and inject gene therapy vectors into. Second because of cell heterogeneity within
