Purpose: Although it is well recognized that SCLC is a chemo and radiosensitive
tumor, only fraction of treated patients have a complete remission, fewer still have
durable remissions. This study was performed to evaluate the clinical effects of IEP
chemotherapy in patients with SCLC.
Materials and Methods: Patients with histologically proven SCLC who has measurable
disease and previously untreated, were eligible. Treatment consisted of ifosfamide 1000
mg/m2 iv infusion for 1 hour on days 1¡­5 with mesna uroprotection;
epirubicin 60 mg/m2 iv on day 1; and cisplatin 20 mg/m2>/sup> iv
infusion on days 1¡­5 with hydration; repeated treatment every 4 weeks.
Results: Twenty four patients(20 males, 4 females) were eligible for response to IEP
chemotherapy. The two patients were excluded because one died before evaluating
response to chemotherapy and the other had brain metastasis. The median age was
61(range 34¡­74). Fifteen patients had a limited disease(LD), nine patients had a
extensive disease(ED). The overall response rate was 86.4%(CR 36.4%, PR 50%). In LD,
response rate was 86.7% (CR 46.7%) and in ED, response rate was 85.7% (CR 14.3%).
The median overall survival time was 43.5 weeks. The median survival time of LD and
ED was 46.5 weeks and 43.5 weeks respectively. The median time to progression was
20 weeks in responders. The toxicity was moderate. One toxic death was observed.
Grade 1 or 2 non-hematologic toxicities consisted of alopecia, nausea and vomiting in all
cases, peripheral neuropathy in 3, hematuria in 2, mucositis in 11, and fever/infection in
6. Hematologic toxic effects included leukopenia( ¡Ãgrade 3, 16.5%), anemia(¡Ã grade 3,
1%), and thrombocytopenia( ¡Ã grade 3, 6.8%).
Conclusions: These results suggest that IEP chemotherapy may be useful as a
treatment strategy in small cell lung cancer, but it's efficacy is equivalent. The phase
III study should be needed.
