Summary TCD50 assay
•
Best assay available for experimental radiotherapy
•
Most relevant for clinical practice
•
Tumour cells remain in situ
•
Dependent only on clonogenic cells
•
All clonogenic cells are assayed, not only some logs
•
Thus also survival of small resistant subgroups of
clonogens can be assayed
•
Good for radiobiological modelling
