Purpose: Etoposide is a schedule-dependent agent and has a synergistic activity with
cisplatin. We evaluated the response rate and the toxicity of prolonged oral etoposide in
combination with intravenous cisplatin for the previously untreated patients with
unresectable stage ¥²B or IV non-small cell lung cancer (NSCLC).
Methods: Between April 1996 and February 1998, 71 patients were enrolled. The
median age was 61 years (range, 36¡­75) and male : female ratio was 54 : 17. Fourteen
patients had stage ¥²B disease and 57 had stage ¥µ. Sixty-two patients had ECOG
performance status of 0 or 1, and 9 had 2. Forty-eight patients had adenocarcinoma, 19
had squamous cell carcinoma and 4 had poorly differentiated NSCLC. Treatment consists
of daily oral etoposide 50§·/m2 in 2 divided doses for 21 days and
intravenous cisplatin 60§·/m2 on day 1. The treatment was repeated every
28 days.
Results: Sixty-four of 71 patients were evaluable. Complete response and partial
response were observed in 1 and 21 patients, respectively. The overall response rate
was 34.4% (95% confidence interval 23.9¡­46.6%) and the median response duration was
30 weeks (range 13¡­53 weeks). The median survival of 71 patients was 56 weeks
(range 3-96+weeks). There was a significantly longer survival in responders (p=0.035).
Toxicities were evaluated by WHO criteria. Hematologic toxicities of grade 3, 4 were as
follows: anemia 12.3%, leukopenia 8.7%, neutropenia 19.2%, thrombocytopenia 1.8%.
Non-hematologic toxicities of grade 3, 4 were as follows: nausea and vomiting 5.9%,
stomatitis 147%, diarrhea 1.5%. Early treatment-related death occurred in 2 patients
(2.8%) due to sepsis.
Conclusion: Combination chemotherapy with prolonged oral etoposide and intravenous
cisplatin is easy to administer and has moderate activity with acceptable toxicities for
NSCLC.
