1
The unidimensional measurement could replace the more complex bidimensional one.
2
Therefore, we aimed to extend the tripartite model in order to describe more specific symptom patterns with unidimensional measurement scales.
3
Rasch analyses showed that each of the factors and the total of factors can be regarded as unidimensional measurement scales.
4
However, some problems concerning the evaluation of non-cytotoxic drugs and unidimensional measurements remain in the new criteria.
5
In contrast to the standard bidimensional WHO criteria, the recently described Response Evaluation Criteria In Solid Tumors are based on unidimensional measurements.
6
Unidimensional measurement does not reflect size or change in size, and therefore the RECIST criteria may not be applicable to all tumor shapes.
7
Conclusions: The use of unidimensional measurements in RCC therapy assessment results in significantly different time to progression classification compared with the use of bidimensional measurements.
