Aims and objectives
To measure response to cancer treatment RECIST (Response Evaluation Criteria in Solid Tumours) is most widely used in clinical practice,
particularly in the scope of clinical trials.
The RECIST system classifies the response into a complete or partial response,
stable or progressive disease,
as displayed schematically in Fig. 1 (1). Nowadays radiologists in the Netherlands Cancer Institute measure lesions using RECIST 1.1,
the most recent available version of RECIST.
Radiologists experience this assessment as a time consuming process.
Given the well defined and standardized methodology of the RECIST system,
the tasks of radiologists may partly be done by less trained personnel such as radiographers.
In a previous small pilot study in 20 patients it was shown that RECIST measurements done by a paramedic are a potential feasible alternative to standard practice where measurements are done by radiologists (2).
The aim of this study was to follow-up on this previous work and evaluate whether tasks can be reshuffled by radiographers perform RECIST-measurements to free radiologists' time.
