[Sensitivity testing of anticancer drugs using the human tumor clonogenic assay]
The response to cancer chemotherapy varies from patient to patient with the same histologic type of tumor. However, anticancer drugs are considerably toxic to the patient, and it is therefore very important to have an accurate knowledge of the sensitivity of anticancer drugs against an individual patient's tumor in establishing successful chemotherapy. We have investigated the sensitivity testing of anticancer drugs using the human tumor clonogenic assay since 1980. Specimens were obtained by aspiration of ascites, pleural effusions and bone marrow and by biopsy of primary and metastatic tumors. Drugs tested in the present study were adriamycin, aclarubicin, THP-adriamycin, mitoxantrone, 40497s (an active compound derived from ifosfamide), mitomycin C, cisplatinum and methotrexate. One hundred and fifty-two specimens were obtained from cancer patients and tested for their drug sensitivity using the assay. Of the 152 specimens, 63 (41%) formed more than 30 colonies in control plates and could be used to evaluate drug sensitivity. Of these, 45 instances were evaluable for examination in an in vitro-in vivo association, and 42 (93%) showed a correlation between in vitro sensitivity and clinical response. In summary, the results indicated that the human tumor clonogenic assay was an excellent technique for testing the in vitro sensitivity of anticancer drugs. However, technical developments yielding higher colony efficiency would be required to facilitate practical use of the assay.
[Establishment of adriamycin-resistant human small-cell lung cancer cells in culture: analysis of the mechanism of resistance and cross-resistance]
An adriamycin-resistant cell line was established in culture by continuous exposure of SBC-3 cells, a cell line of human small-cell lung cancer, to increasing concentrations of adriamycin, followed by a cloning procedure. The resistant cells (SBC-3/ADM) were 30 times more resistant to the drug than the parent cells in terms of 70% lethal dose, determined by soft agar clonogenic assay. Uptake studies using [3H] daunomycin, which was completely cross-resistant to adriamycin, showed decreased influx and enhanced efflux of the agent. This resistance to adriamycin may be attributed to an alteration in membrane transport, resulting in reduced intracellular accumulation of the drug. Using the SBC-3/ADM cells, the activity of a variety of drugs was analyzed by soft agar clonogenic assay in order to search for a means of circumventing drug resistance. The SBC-3/ADM cells were markedly resistant to anthracycline antibiotics such as THP-adriamycin and 4'-epi-adriamycin. The cells were also resistant to structurally or pharmacodynamically unrelated compounds such as vincristine, mitomycin C, 40497S, an active compound of ifosfamide, and etoposide. However, the cells were as sensitive to mitoxantrone as the parent cells, and were considerably susceptible to cisplatin. These results suggest that mitoxantrone and cisplatin may exert a sufficient degree of activity for use against small-cell lung cancer resistant to adriamycin.
