Chemotherapy is the only therapeutic modality applicable to patients with advanced pulmonary epidermoid carcinoma (PEC). However, the results of chemotherapy to PEC remain unsatisfactory. It is very important to have an accurate knowledge of the sensitivity of anticancer drugs against PEC in order to establish a successful chemotherapy. The in vivo sensitivity of 12 anticancer drugs was investigated using PEC cell line (EBC-1) xenografts in hamsters.
In the present study, adriamycin, ifosphamide, mitomycin C, methotrexate and cisdichlorodiammineplatinum (II) showed antitumor activity against EBC-1 cells, but the other 6 drugs (ACNU, bleomycin, 5-fluorouracil, neocarzinostatin, procarbazine and vincristine) have no antitumor activity against EBC-1 cells. These results suggest that combination chemotherapy with 3 or 4 drugs with antitumor activity in the present study may be effective to PEC.
