Neurocytoma is a rare tumor of central nervous system (CNS). The present study is an analysis of benefits and risks of radiotherapy (RT) after surgery.
METHODS
Following a retrospective evaluation of 2186 CNS tumors treated at the university oncology institute,
6 cases of neurocytoma were found. These 6 cases were analyzed according to patient sex, age,
location of tumor, treatment type, and survival.
RESULTS
Median patient age was 40 years. Four tumors were centrally located, and the remaining 2 tumors
were located in the extraventricular region. All of the patients received 50–60 Gy of conventional
irradiation. Median length of follow-up was 51 months (range: 15–88 months). In this study, 5-year
survival rate was 60%.
CONCLUSION
Primary treatment for neurocytoma is surgery. RT is suggested only for subtotally resected tumors,
recurrent tumors, or tumors with atypical characteristics due to delayed side effects.
