Table 2.

Sensitivity of the primary cells to the different treatments.

The IC50 for the different drugs ± SD is shown. 786-O cells are sensitive to sunitinib and erlotinib and serve as the reference. We considered the cells to be sensitive to a drug if the concentration giving 50% inhibition of cell proliferation (IC50) was lower than or equal to the IC50 in 786-O cells and was considered resistant if the IC50 was higher than for 786-O cells. CC, M and TF cells were derived from tumors of metastatic patients. When cells are sensitive to a given treatment, the value is presented on a white background but if cells are insensitive it is on a black background.
