The synergism of combined high‐dose etoposide with standard dose cisplatin (HD‐EP) was evaluated in 20 patients who had relapsed after treatment of small cell lung cancer. Each patient was given etoposide at 500 mg/m 2 /day on days 1 to 3 and cisplatin at 80 mg/m 2 (two patients given 120 mg/m 2 ) on day 1; autologous bone marrow was not transplanted. Five patients were given recombinant human granulocyte colony‐stimulating factor (rhG‐CSF, 50 μg/m 2 ) in an attempt to reduce HD‐EP induced neutropenia. The overall response was 50% (9 of 18); one complete response (6%), eight partial responses (44%), seven no change (39%), and two progressions of disease (11%). Of the 18 evaluable patients, 12 had been treated with regimens of conventional doses of etoposide with conventional doses of cisplatin or carboplatin, and of these, five (42%) achieved a partial response. The median duration of response was 8.4 weeks (range, 5.3 to 17.7) and the median survival time was 20.3 weeks (range, 1.6 to 91). All of the patients developed severe myelosuppression; rhG‐CSF did not shorten the period of the leukopenia. Mucositis and liver dysfunction were the major nonhematologic manifestations of toxicity. Two treatment‐related deaths resulted from sepsis. These results suggest that the activities of high doses etoposide with standard doses of cisplatin are synergistic against small cell lung cancer.
