Non-small cell lung cancers (NSCLC) are often resistant to chemotherapy. Cisplatin has shown the most activity against all the histological subtypes and is now used in most combined treatment programmes. Interferon (IFN)-alpha has been shown to potentiate cisplatin and other drugs experimentally and in clinical trials involving NSCLC. We are looking at the responses of different NSCLC cell lines to cisplatin (P), etoposide (VP-16) and IFN [recombinant human IFN-alpha 2c (IFN-alpha) and IFN-gamma 1b (IFN-gamma)], individually and in combination. We then compare the results with those from a clinical trial of etoposide and cisplatin with interferon in advanced NSCLC. We report here the results from the first of our cell lines, established from a large cell anaplastic carcinoma. We have confirmed earlier findings that NSCLC cell lines are not sensitive to either IFN-alpha or IFN-gamma alone. However a combination of IFN-alpha and IFN-gamma does reduce cell proliferation in our cell lines. This IFN combination potentiates the response of the cells to etoposide far more than to cisplatin. There is a trend towards greater activity when a combination of cisplatin and etoposide is used, compared with the activity of either drug alone. This effect is further increased by the interferon combination. |
