title: Phase II study of cisplatin, ifosfamide with mesna, and etoposide (PIE) chemotherapy for advanced non-small cell lung cancer.
abstract: Ifosfamide has shown promising single-agent activity in non-small cell lung cancer (NSCLC). We combined ifosfamide (1,800 mg/m2 plus mesna 1,100 mg/m2 by intravenous [IV] continuous infusion daily for 3 days) with cisplatin (20 mg/m2 IV for 3 days) and etoposide (80 mg/m2 IV for 3 days) and treated 41 chemotherapy-naive patients with recurrent or metastatic NSCLC. Fifteen (40.5%) of the 37 evaluable patients had objective responses (1 complete and 14 partial). Patients with good performance status (Zubrod scale 0 or 1) had a higher response rate than the patients with poor performance status (Zubrod scale 2) (11 of 21 patients [52.4%] versus four of 16 [25.0%]), but the difference was not statistically significant (P = .09). Median survival has not been reached, with 17 patients still alive after a median follow-up of 39 weeks (range, 21 to 56). Significant myelosuppression occurred, with granulocytopenia being the dose-limiting toxicity. Overall, treatment was well tolerated. Considering the pooled response rate of 32% with cisplatin/etoposide regimens and the previous experience from our institution, the results with this three-drug regimen are very encouraging, and its further investigation is warranted.
