Abstract
Thirty-nine patients with low grade cystic cerebellar astrocytomas were treated at the University of Washington and Children's Orthopedic Hospital in Seattle, Washington, between 1955 and 1977; 29 were treated with partial or complete resection alone, and 10 received radiation therapy after various types of surgical procedures. With a mean follow-up time of 7 years, the survival rate for patients who had complete resections of their primary disease was 100%. The relapse-free survival rate was 82%. The relapse-free survival rate for patients treated primarily with partial resection alone was 36%. Postoperative irradiation after partial resection for both primary and recurrent disease resulted in a relapse-free survival rate of 83%. If complete tumor excision is not possible, postoperative radiation therapy is recommended following partial resection.
