in an attempt to find how much the low therapeutic effectiveness of antitumor drugs against so-called chemotherapy-refractory tumors such as colon carcinoma depends on drug sensitivity at the cellular level , sensitivity of five carcinoma cell lines ( three colorectal , one pancreatic , and one renal ) to nine typical anticancer agents was compared in vitro with that of four generally chemotherapy-susceptible leukemia cell lines .
