1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundThe 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.

objectivesTo 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.

methods27 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).

resultsIn 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.

conclusionsThere 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.
