Translational cancer research transforms new
knowledge obtained from basic research into innovative therapeutic and
diagnostic tools for cancer patients. The identification of molecular pathways and mechanisms playing a key role in
tumor growth and progression provided a number of new targets, potential probes
and drugs for diagnostic and therapeutic intervention in oncology. Molecular
imaging with its ability to evaluate in vivo complex biological processes such
as proliferation, apoptosis, angiogenesis, gene expression, receptor/ligand
interactions, transport of substrates and metabolism of nutrients in human
cancers can accelerate this transfer process. Imaging technologies such as
PET/CT and SPECT/CT can be employed in pre-clinical and clinical experimental
settings for visualization of target expression or function as well as
modulation of downstream pathway. In this framework our research activity is
focused on the development and characterization of new probes for imaging of
the expression of tumor targets or drug-induced modulation of downstream
pathways. To this end several tumor models are available in our laboratory in
order to test new tracers and drugs. In particular we characterized and
validated tracers for imaging of tumor proliferation, apoptosis and
angiogenesis and tested the effects of several tyrosine kinase inhibitors
(TKIs). For instance non-invasive imaging of proliferation with 18F-Fluorothymidine
(18F-FLT) and PET was used to detect MET-mediated resistance in non-small
cell lung cancer (NSCLC) and to monitor its reversal by MET inhibitors. We showed
that the persistently high uptake of 18F-FLT in tumors after
treatment with EGFR TKIs identified resistance whereas the significant
reduction of tracer uptake in response to treatment with MET inhibitors
indicated the reversal of MET-mediated resistance. The major clinical
implication of this study was to provide an adaptive imaging biomarker for
translational targeted therapy in NSCLC patients.
Longitudinal imaging studies with 18F-FLT in H1993 xenografts
bearing MET amplification. The persistently high uptake of 18F-FLT
in tumors after treatment with erlotinib identified resistance whereas the
significant reduction of tracer uptake in response to MET TKI indicated the
reversal of MET-mediated resistance.
