Effects of different combination schedules of cetuximab with chemotherapeutics in SUM102 cells. Cells were treated with four different combination schedules: 1) 72 h cetuximab followed by 72 h chemotherapy, 2) 72 h chemotherapy followed by 72 h cetuximab, 3) 72 h concurrent chemotherapy and cetuximab, and 4) 144 h concurrent chemotherapy and cetuximab. A) Growth inhibitory effects of cetuximab and carboplatin combinations. B) Combination analysis of cetuximab and carboplatin treatments. C) Growth inhibitory effects of cetuximab and paclitaxel combinations. D) Combination analysis of cetuximab and paclitaxel treatments. E) Growth inhibitory effects of cetuximab and 5-fluorouracil combinations. F) Combination analysis of cetuximab and 5-fluorouracil treatments. G) Growth inhibitory effects of cetuximab and doxorubicin combinations. H) Combination analysis of cetuximab and doxorubicin treatments. Combination Index (CI) values below one are synergistic, equal to one are additive, and greater than one are antagonistic.
