Does a more refined categorisation of tumour response and/or progression improve prediction of overall survival in RECIST 1.1?

In a recent analysis by the RECIST Working Group, EORTC researchers had explored whether a more refined categorisation of tumour response or various aspects of progression could improve prediction of overall survival in the Response Evaluation Criteria in Solid Tumours (RECIST) database. They found that modelling target lesion tumour growth did not improve the prediction of overall survival above and beyond that of the other components of progression. Read more here.
