Prostate Cancer
Gene therapy
There is also considerable activity in the area of gene therapy
and several academic and commercial organisations have R&D
and clinical programmes in this area. An allied approach is
to design molecules that bind to specific sequences of DNA.
One is a compound G3139 (Genta Pharma), called an anti-sense
oligonucleotide, which has been designed to bind to a cancer-causing
gene called bcl-2 found in prostate and some other tumour
types. It is hoped that by binding to the gene, it will switch
it off and thus stop the cancer growing. The results of a
Phase 1 trial of G3139 in hormone-resistant prostate cancer
in combination with mitoxantrone were sufficiently encouraging
to justify larger studies.
These are difficult areas of research, but the germs of success
are there. If the technical difficulties can be overcome,
then vaccination and gene therapy are likely to make a major
contribution to cancer prevention and cure in the years to
come.
