Primary analysis of a phase II randomized trial Radiation Therapy Oncology Group (RTOG) 0212: impact of different total doses and schedules of prophylactic cranial irradiation on chronic neurotoxicity and quality of life for patients with limited-disease small-cell lung cancer.

ABSTRACT:

Purpose

To determine the effect of dose and fractionation schedule of prophylactic cranial irradiation (PCI) on the incidence of chronic neurotoxicity (CNt) and changes in quality of life for selected patients with limited-disease small-cell lung cancer (LD SCLC).

Methods and materials

Patients with LD SCLC who achieved a complete response after chemotherapy and thoracic irradiation were eligible for randomization to undergo PCI to a total dose of 25 Gy in 10 daily fractions (Arm 1) vs. the experimental cohort of 36 Gy. Those receiving 36 Gy underwent a secondary randomization between daily 18 fractions (Arm 2) and twice-daily 24 fractions (Arm 3). Enrolled patients participated in baseline and follow-up neuropsychological test batteries along with quality-of-life assessment
