MedicalResearch.com: What is the background for this study? What are the main findings?
Prof. Johnson: Based upon retrospective series looking at the ability of interim PET to predict the outcomes of treatment, we aimed to test the idea of modulating treatment in response to an early assessment of the response to ABVD: could we safely reduce the amount of treatment by omitting bleomycin in the group who had responded well? Although the risk of severe toxicity from bleomycin is generally low, for the small number of patients who experience it, it can be life-changing or even fatal. We also wanted to test whether it might be possible to reduce the use of consolidation radiotherapy by comparison to our previous trials, and this seems to have worked too: we used radiotherapy in less than 10% of patients in RATHL, as compared to around half in our previous trials. We have seen better survival figures than in our previous studies with less treatment overall, so it feels as though we are on the right track.
