The goal of this study was to analyze clinical, prognostic and therapeutic factors in a large series of histologically proven brainstem gliomas. Between 1997 and 2007, 104 patients with a histologically proven brainstem glioma were retrospectively analyzed. Data about clinical course of(More)

Therefore, treatment decisions are based on small, mostly retrospective studies and the role of chemotherapy has remained(More)
The invasion front pattern of squamous cell carcinoma (SCC) is a conspicuous histological phenomenon, which is assessed without precise criteria.

A retrospective analysis of 76 surgically(More)
