The effectiveness was apparent not only by a decrease in tumor size but also by an inhibition of lung metastases.
The mean decrease in tumor size determined by MRI measurements was 36%95%5% confidence interval, 7%-66%).
One of three individuals at the 108 level showed a 39% radiologic decrease in tumor size by cross-section and 75% by volume.
Diagnosis was difficult given the spontaneous decrease in tumor size.
In this combinatorial study, there was an approximate ten-fold decrease in tumor size and survival was extended by ~12 days [60].
Using (FDG) PET imaging to assess response will, in many cancers, typically demonstrate rapid reduction in tumor (18F-FDG) signal with effective therapy, a decline not uncommonly antedating decrease in tumor size [12, 13].
The goal in patients would be to have a maximum exposure time to sunitinib which is associated with longer time to tumor progression, longer overall survival, and greater decrease in tumor size [43].
Moreover, for small lesions or during an effective treatment with a decrease in tumor size, when partial-volume effect may result in an underestimation of [18F]FDG uptake, SUVmax may be best suited as metabolic index than the other SUVs [12].
Here we report that diclofenac treatment causes a 60% decrease in tumor size.
Stable disease (SD) was defined as no significant increase or decrease in tumor size, and progressive disease was defined as the development of new, previously undetected lesions or ≥25% increase in the size of a pre-existing lesion.
However, our results are contradictory to this hypothesis and contradict the recent studies that reported decrease in tumor size of implanted glioma (and other tumors) as well as the decrease in permeability after treatment with VEGFRs inhibitor [25], [26].
