ABSTRACT

Objective:

To explore overall survival(OS) and prognostic factors of brainstem gliomas (BSG) after intensity modulated radiotherapy (IMRT) by a retrospective single-center analysis.

Methods:

A total of twenty-one patients with BSG were collected in the Department of Radiation Oncology, Peking University Cancer Hospital from January 2012 to September 2019. All patients underwent IMRT. OS and potential prognostic factors were analyzed, including gender, age, operation type, imaging classification, tumor location, WHO grade, chemotherapy, radiotherapy pattern, time interval between morbidity and the first treatment, and radiation dose.

Results:

Eighteen of twenty-one patients were followed up more than 3 months. The median follow-up time was 15.5 (5.3-25.6) months. The median overall survival (mOS) was 20 (14.1-25.8) months. The 1 and 2-year OS rates were 86.2% and 34.5% respectively. Operation type, imaging classification, tumor location, WHO grade and radiotherapy pattern were the prognosis factors ( χ2=4.829-20.261, P<0.05).

Conclusions:

Patients with maximal safe surgical resection, focal endogenesis / exogenesis, tumor located in mesencephalon, low-grade gliomas and/or received postoperative radiotherapy have a better prognosis. It has certain reference value for guiding the clinical practice.
