Whole brain irradiation for metastases from lung carcinoma. A clinical investigation.

Sixty-nine consecutive patients with brain metastases from lung carcinoma were randomly allocated to one of two radiation therapy schedules: 30 Gy/10 fractions/2 weeks or 50 Gy/20 fractions/4 weeks. The improvement rate for neurologic function was similar in the two groups. The median survival times for patients receiving the short course and the long course were 4 months and 3 months, respectively. The half-year survival rate was 42 per cent after the short course and 14 per cent after the long course (p less than 0.05). Performance status and lactate dehydrogenase were other factors which significantly influenced the half-year survival rate.
