Randomized Phase II/III Trial of Prophylactic Cranial Irradiation With or Without Hippocampal Avoidance for Small Cell Lung Cancer

NRG Oncology·interventional·Posted Dec 18, 2015·Updated May 19, 2026

In Brief

A Phase 3 clinical trial evaluating Three-Dimensional Conformal Radiation Therapy and Intensity-Modulated Radiation Therapy for Extensive Stage Small Cell Lung Carcinoma and Limited Stage Small Cell Lung Carcinoma. Completed, enrolled 418 participants across 281 sites in 2 countries.

Detailed Summary

This randomized phase II/III trial studies how well whole-brain radiation therapy works and compares it with or without hippocampal avoidance in treating patients with small cell lung cancer that is found in one lung, the tissues between the lungs, and nearby lymph nodes only (limited stage) or has spread outside of the lung in which it began or to other parts of the body (extensive stage). Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. The hippocampus is part of the brain that is important for memory. Avoiding the hippocampus during whole-brain radiation could decrease the chance of side effects on memory and thinking. It is not yet known whether giving whole-brain radiation therapy is more effective with or without hippocampal avoidance in treating patients with small cell lung cancer.
