Combination Chemotherapy and Radiation Therapy in Treating Patients With Limited-Stage Small Cell Lung Cancer
RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining chemotherapy with radiation therapy may kill more cancer cells.
PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy before, during, and after radiation therapy in treating patients who have limited-stage small cell lung cancer.
Drug/Agent Toxicity by Tissue/Organ
Drug: amifostine trihydrate
Drug: topotecan hydrochloride

|Official Title:||Phase I-II Study of Topotecan and Paclitaxel Followed by High-Dose Thoracic Radiation Therapy With Concomitant Cisplatin/Etoposide and Amifostine in Limited-Stage Small Cell Lung Cancer|
- Survival at 2 years [ Designated as safety issue: No ]
- Local progression-free survival at 2 years [ Designated as safety issue: No ]
- Tolerabiltiy and toxicity [ Designated as safety issue: Yes ]
- Overall survival [ Designated as safety issue: No ]
- Time to progression [ Designated as safety issue: No ]
|Study Start Date:||February 2001|
- Determine the maximum tolerated dose of thoracic radiotherapy administered with cisplatin, etoposide, and amifostine preceded and followed by topotecan and paclitaxel in patients with limited stage small cell lung cancer (phase I closed to accrual as of 5/27/2004).
- Determine the two-year survival of this patient population treated with this regimen.
- Determine the two-year, progression-free local control rate in this patient population treated with this regimen.
- Assess the tolerability of this treatment regimen in these patients.
- Determine the antitumor activity of this regimen in these patients.
- Determine the overall survival and overall time to progression in this patient population treated with this regimen.
OUTLINE: This is a multicenter, dose-escalation study of thoracic radiotherapy (TRT).
Patients receive topotecan IV on days 1-5 and paclitaxel IV over 3 hours on day 5. Patients receive filgrastim (G-CSF) subcutaneously (SC) daily beginning 24 hours after the last dose of chemotherapy and continuing until blood counts recover. Treatment repeats every 3 weeks for 2 courses.
After 2 courses of topotecan and paclitaxel, patients undergo TRT twice daily for 5 consecutive days for 5 weeks. During TRT, patients receive cisplatin IV, oral etoposide, and amifostine SC daily prior to TRT.
At 4 weeks after completion of TRT, patients receive 2 additional courses of topotecan, paclitaxel, and G-CSF every 3 weeks followed by prophylactic cranial irradiation.
Cohorts of 3-6 patients receive escalating doses of TRT until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity (phase I closed to accrual as of 5/27/2004).
Patients are followed every 3 months for 1 year, every 4 months for 1 year, and then every 6 months for 3 years.
PROJECTED ACCRUAL: A total of 3-73 patients will be accrued for this study (phase I closed to accrual as of 5/27/2004).
