An analysis of 13 patients with brain stem glioma in adult, treated between 1998 and
1995, was undertaken. The purpose of this study is to establish the correlations between
the MRI appearance, clinical findings and the prognosis. Based on the MRI appearance
of the tumor at the time of clinical diagnosis, tumors were divided into four types ;
intrinsic diffuse, intrinsic focal, intrinsic cervicomedullary and exophytic type. Five
patients we diagnosed pathologically by means of stereotactic biopsy(2 patients) and
open surgery(3 patients), the rest were diagnosed on the basis of MRI appearance. All
patients had received radiation therapy, and 11 patients had received chemotherapy
during or immediately after radiation therapy. The methods of radiation therapy were
either conventional or hyperfractionated type.
The histological features were not always correlated with the prognosis. MRI and
clinical findings could suggest the prognosis and probably the histological nature of the
tumors. Moreover, response of initial radiotherapy and chemotherapy was considered to
be a good prognostic factor. Seven of the 13 patients had response to the initial
radiotherapy and chemotherapy. The poor prognostic factors determined in our study
were 1) diffuse type 2) rapid growing with rim enhancement in spite of initial
radiotherapy and chemotherapy 3) malignant pathologic finding 4) intratumoral necrosis
after radiotherapy 5) multiple site involvement 4) good response to initial radiotherapy
and chemotherapy.
