Abstract

OBJECTIVE

The aim of the present study was to evaluate treatment outcomes for adult patients with medulloblastoma who received craniospinal irradiation following surgery at Dokuz Eylül University Radiation Oncology Department.

METHODS

Twelve patients were evaluated retrospectively. Median age was 31 years (range: 18-55 years). According to Chang staging system, 3 (25%) of the patients were T1, 2 (17%) were T2, 5 (42%) were T3, and 1 (8%) was T4; 1 patient could not be staged due to inadequate preoperative imaging. Tumor location, stage, presence of residual disease, duration between surgery and radiotherapy (RT), age, and sex were evaluated as prognostic factors. Statistical analyses were conducted using Kaplan-Meier method and SPSS for Windows, Version 15.0 (SPSS Inc., Chicago, IL, USA).

RESULTS

Median dose was 36 Gy (range: 32-44 Gy) to craniospinal field and 54 Gy (range: 50-56 Gy) to primary tumor location. Median follow-up time was 62 months (range: 4-212 months). Five-, 10-, and 15-year overall survival rates were 79%, 63%, and 63%, and 5-, 10- and 15-year progression-free survival rates were 63%, 63%, and 63%, respectively. No statistically significant prognostic factor was found for survival rate. Three (25%) patients developed serious hematological toxicity during RT course. No grade 3 or 4 late side effect was observed.

CONCLUSION

Despite the limited number of cases, results are consistent with the literature. Evaluation of features of this rare disease requires studies with larger number of.
