Correlations between the cytotoxic activites (SI %) for the indicated pairs of standard cytotoxic drugs in gastric cancer samples at concentrations selected to provide optimal activity variation. These concentrations were: cisplatin, oxaliplatin and mitomycin-C 10 μM; 5-FU and irinotecan 100 μM; doxorubicin 1 μM; docetaxel 20 μM. Abbeviations: r, correlation coefficient; P, the level of statistical significance.
