Abstract

Objective: To determine the long-term outcome of resected choroid plexus papillomas (CPPs). Methods: Medical records and histologic specimens were reviewed for 41 patients (19 male, 22 female; median age, 36 years; range, 6 months to 74 years) with CPP seen between 1974 and 2000. Tumor locations were as follows: 76%, fourth ventricle; 17%, lateral ventricle, and 7%, third ventricle. Fifty-six percent had a gross total resection (GTR) and 44% had a subtotal resection (STR). Median follow-up was 6.5 years. Results: Five-year local control, distant brain control, and overall survival were 84%, 92%, and 97%, respectively. Comparison of GTR and STR at 5 years showed a significant increase in local control (100% vs. 68%; P = 0.04) but not in overall survival (100% vs. 94%). Even after STR, only 50% of patients required a subsequent resection for recurrence. Addition of radiation therapy to initial STR did not seem to influence outcomes. At first relapse, GTR was accomplished in 1 patient, and only STR was accomplished in the others. Addition of radiation therapy to STR in our study led to disease control in half the patients treated, and STR alone led to disease control in only a quarter of the patients. Second relapses were treated palliatively with radiation therapy. Conclusions: Surgical resection is the treatment of choice for CPPs. After initial STR, reoperations for recurrence are required only half the time. Therefore, there seems to be no role for radiation therapy after initial STR. For STRs at first relapse, local control outcome is poor.
