No suggestion was made that all forms of cancer are the same. But to the best of my knowledge, all cancers have distinctive cancer cell surface chemistry - which may vary somewhat between individual genotypes, but is generally similar for clades of cancers between individuals. In the targeted paradigm, cancer research is a matter of identifying that chemistry, and then programming your hunter-killers to that scent. These two jobs - (a) take an individual's cancer biopsy and identify its signature, or match it to an established library of signatures and (b) construct a homing mechanism for that signature - are core competencies for today's cutting edge biotechnology. There are many, many examples from the past few years of researchers doing exactly what you scoff at in the laboratory, for specific cancers in laboratory animals. In summary: one technology platform, many different implementations, a large library of cancer signatures built from the results of individual therapies.
