Glioma treatment response assessment in clinical trials

Glioma treatment response assessment in clinical trials has undergone numerous revisions with a number of criteria having been developed over the years. This has been necessary as a result of a number of factors:

  1. improved understanding of tumour biology (e.g. appreciating importance of non-enhancing tumour)
  2. realisation that existing criteria are flawed (e.g. measuring necrotic tumours)
  3. changes in imaging parameters

Although superficially most share similarities, as the saying goes, the devil is in the details.

Currently the most widely used system to assess first line treatment response in glioblastomas (and lower grade diffuse astrocytomas) are the Response Assessment in Neuro-Oncology Criteria (RANO), which were published in 2010 1.
