OBJECTIVE: In order to perform effective translational research for cancer
therapy, we need to employ pre-clinical models which reflect the clinical
situation. The purpose of this study was to quantitatively compare the vascular
architecture of human colorectal cancer and experimental tumour models to
determine the suitability of animal models for vascular studies and antivascular
therapy. METHODS: In this study we investigated the three-dimensional properties
of colonic tumour vasculature in both human clinical tissues (normal mucosa
control [n=20], carcinoma [n=20] and adenoma [n=6]) and murine colorectal
xenografts (LS147T [n=6] and SW1222 [n=6]). Scanning Electron Microscope
Stereoimaging (SEM) and X-ray Micro-Computed Tomography (Micro-CT) methods were
employed for 3D analyses of the vascular corrosion casts from these tissues.
RESULTS: Morphological measurements showed that there were significant
differences in the underlying morphology in the different tissues. Of the studied
xenografts, LS147T is more consistently similar to the vascular architecture of
the human carcinoma than SW1222. The only reversal of this is for the
inter-vessel distance. CONCLUSION: While SEM stereoimaging provided better
surface detailed resolution of the corrosion casts, it was complimented by the
fully 3D micro-CT method. Comparison made between the xenografts and clinical
tumours showed that the LS147T xenografts shared many similarities with the
clinical tumour vasculature. This study provides insight into how to select the
most suitable pre-clinical models for translational studies of clinical cancer
therapy.
