简要总结
RATIONALE: Radiation therapy uses high energy x-rays to kill tumor cells. This may be an effective treatment for extensive stage small cell lung cancer.
PURPOSE: This randomized phase II trial is comparing how well radiation therapy to the brain works when given with or without radiation therapy to other areas of the body in treating patients with extensive stage small cell lung cancer.
详细描述
OBJECTIVES:
Primary
- To compare the 1-year overall median survival rate in patients with extensive stage small cell lung cancer treated with prophylactic cranial irradiation with vs without consolidative extracranial radiotherapy following platinum-based chemotherapy.
Secondary
- To compare treatment-related adverse events in these patients.
- To evaluate patterns of failure in these patients.
- To compare the time to first failure in these patients.
- To evaluate the percentage of the planned radiotherapy dose given to each site.

结局指标
主要结局
Overall Survival (12-month Rate Reported)
时间窗: From randomization to last follow-up. Analysis occurred after all patients had been potentially followed for at least 12 months. Maximum follow-up at time of analysis was 46.0 months.
Survival time is defined as time from randomization to date of death from any cause and is estimated by the Kaplan-Meier method. Patients last known to be alive are censored at the date of last contact. This analysis was planned to occur when all patients had been potentially followed for at least 12 months. The 12-month rate is reported.
次要结局
- Percentage of Patients Experiencing a Grade 3 or Higher Adverse Event(From randomization to last follow-up. Analysis occurred after all patients had been potentially followed for at least 12 months. Maximum follow-up at time of analysis was 46.0 months.)
- Patterns of Failure - Number of Patients With Failure by Site(From randomization to last follow-up. Analysis occurred after all patients had been potentially followed for at least 12 months. Maximum follow-up at time of analysis was 46.0 months.)
- First Failure (12-month Rate Reported)(From randomization to last follow-up. Analysis occurred after all patients had been potentially followed for at least 12 months. Maximum follow-up at time of analysis was 46.0 months.)
- Percentage of Planned Radiotherapy Dose (All Sites) That Was Delivered(From start to end of radiation therapy; up to 32 days for Prophylactic Cranial Irradiation arm, up to 68 days for Prophylactic Cranial Irradiation + Consolidation Radiotherapy arm.)
