Negative phase II study of 5-fluorouracil with high-dose leucovorin in non-small cell lung cancer.
Fourteen patients with inoperable or recurrent non-small cell lung cancer (NSCLC) were treated with 5-fluorouracil (5-FU) plus high-dose leucovorin (LV). The administration schedule was 2 h infusion of LV at a dose of 500 mg/m2 and 30 min infusion of 5-FU at a dose of 600 mg/m2 given 1 h after the start of the LV infusion. This regimen was followed weekly, six times. No objective (complete or partial) response was seen in any of the patients. Ten patients showed no change and there were four with progressive disease. One patient experienced grade 3 leukopenia after two courses of treatment. Another experienced grade 2 leukopenia. One patient experienced grade 2 vomiting and six, skin pigmentation. Other myelosuppressive effects and non-hematologic toxicities, including diarrhea and mucositis, were mild. It was concluded that the schedule of 5-FU with high-dose LV therapy employed could not be expected to produce a response rate greater than or equal to 20% against NSCLC. 5-FU plus high-dose LV therapy was, therefore, considered to be ineffective against NSCLC with the schedule of administration followed.
