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

objective and importanceThe first case was recently reported of tumor seeding by glioblastoma multiforme (GBM) after stereotactic biopsy. This occurred despite radiosurgical treatment of the lesion post-biopsy. We report the first case of metastatic seeding along the needle biopsy tract of a GBM in which the tract was within the treatment field of subsequent fractionated radiation therapy. CLINICAL PRESENTATION: A 56-year-old man presented with left-sided focal motor seizures. An MRI showed an enhancing right cingulate gyrus lesion.

interventionA stereotactic biopsy of the lesion disclosed GBM. Radiation therapy was begun 25 days after biopsy and was completed 39 days thereafter. The biopsy tract received a minimum of 60 Gy. Subsequent magnetic resonance scanning showed the lesion to have doubled in size and evidence of enhancement along the biopsy tract. At surgery, specimens obtained from the biopsy tract, as determined using surgical navigation, revealed GBM.

conclusionSeeding of the biopsy tract, radioresistance and the time interval until radiotherapy are the most likely explanations for tumor growth along the biopsy tract in this case. Consideration should be given for an early start to radiotherapy among those who undergo stereotactic biopsy for GBM. Further research will allow one to determine the radiosensitivity of these tumors and determine which patients may benefit from a radiosurgical or fractionated radiotherapy boost to the biopsy tract.
