Dichloromethotrexate, infusional cisplatin, and infusional 5-fluorouracil for locally advanced or metastatic non-small cell lung cancer : a MAOP study

The combination of dichloromethotrexate, cisplatin, and infusional 5-fluorouracil was evaluated as treatment for non-small-cell lung cancer in a phase II trial using 43 evaluable patients. Grade III or IV toxicity included thrombocytopenia (21%), leukopenia (14%), nausea/vomiting (14%), mucositis (9%), infection (5%), and other (16%). There were six responders (14%), with a 95% confidence interval of [5%, 28%]. Two additional patients achieved a 50% reduction in cross-sectional tumor size that was not documented twice. Median survival time was 6.5 months. This combination is not considered sufficiently active for further evaluation in this disease.
