Abstract

BACKGROUND: The clinical course of glioblastoma multiforme is characterised by invasive growth and regular recurrence. Many genetic alteration have been identified in the genesis of the disease. However, information about immunohistochemical expression in recurrent lesions is sparse. OBJECTIVES: To determine (1) whether the p53/mdm2/EGFR/msh2 expression pattern differs in initial v recurrent glioblastoma multiforme; (2) whether a possible change in expression correlates with prognostic variables (progression-free survival time, total survival time); and (3) whether chemotherapy in addition to surgery and radiotherapy influences the p53/mdm2/EGFR/msh2 expression profile. METHODS: 27 patients were studied. They met the following criteria: histologically confirmed diagnosis of glioblastoma multiforme (WHO IV); total tumour resection at initial craniotomy; at least one re-craniotomy for glioblastoma multiforme recurrence; age 21 years or older. All underwent radiotherapy of at least 54 Gy, and 17 received additional chemotherapy. Immunohistochemical staining of initial tumours and recurrences was done with the following monoclonal antibodies: anti-p53 (DO-1), anti-mdm2 (IF-2), anti-EGFR (H11), and anti-msh2 (AB-1). RESULTS: In comparison with the initial tumour, recurrent lesions were characterised by reduced expression of p53 (p < 0.0001) and msh2 (p = 0.0012), while the numbers of mdm2 (p = 0.02), EGFR (p < 0.0001), and msh2 positive specimens (p < 0.0001) were reduced. Chemotherapy was associated with reduced msh2 expression (p < 0.0001). Immunohistochemical variables were not associated with patient survival. CONCLUSIONS: There are significant differences in the p53/mdm2/EGFR/msh2 expression patterns in initial v recurrent glioblastoma multiforme. There may be interactions between chemotherapy and changes in the msh2 expression.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
