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

backgroundWe have previously developed (11)C-erlotinib as a new positron emission tomography (PET) tracer and shown that it accumulates in epidermal growth factor receptor (EGFR)-positive lung cancer xenografts in mice. Here, we present a study in patients with non-small cell lung cancer (NSCLC) investigating the feasibility of (11)C-erlotinib PET as a potential method for the identification of lung tumours accumulating erlotinib.

methodsThirteen patients with NSCLC destined for erlotinib treatment were examined by contrast-enhanced computed tomography (CT), (11)C-erlotinib PET/low-dose CT and (18)F-fluoro-2-deoxy-D-glucose ((18)F-FDG) PET/low-dose CT before start of the erlotinib treatment. After 12 weeks treatment, they were examined by (18)F-FDG PET/contrast-enhanced CT for the assessment of clinical response.

resultsOf the 13 patients included, 4 accumulated (11)C-erlotinib in one or more of their lung tumours or lymph-node metastases. Moreover, (11)C-erlotinib PET/CT identified lesions that were not visible on (18)F-FDG PET/CT. Of the four patients with accumulation of (11)C-erlotinib, one died before follow-up, whereas the other three showed a positive response to erlotinib treatment. Three of the nine patients with no accumulation died before follow-up, four showed progressive disease while two had stable disease after 12 weeks of treatment.

conclusionOur data show a potential for (11)C-erlotinib PET/CT for visualizing NSCLC lung tumours, including lymph nodes not identified by (18)F-FDG PET/CT. Large clinical studies are now needed to explore to which extent pre-treatment (11)C-erlotinib PET/CT can predict erlotinib treatment response.
