Changes in CT morphology can be an independent response marker for patients receiving regorafenib for colorectal liver metastases: retrospective pilot study.
Article in BMC cancer, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundRegorafenib is a multi-kinase inhibitor, which was shown to be effective for patients with metastatic colorectal cancer refractory to standard therapies. However, its patterns of response has not yet been fully understood.
methodsClinical records of 10 patients who received regorafenib for evaluable colorectal liver metastases were reviewed. Response to chemotherapy was evaluated with the RECIST and morphologic response criteria, and its clinical relevance was analyzed.
resultsAll patients received multiple lines of fluorouracil-based chemotherapy before regorafenib. The median follow-up duration after introduction of regorafenib was 4.9 months (range, 2 to 12.5 months). Median number of chemotherapy cycles was 2 (range, 1 to 15). In size-based response evaluation, 4 patients presented SD and 6 patients showed PD according to the RECIST. In non-size-based response evaluation, 3 patients were classified as optimal morphologic response and 7 patients were categorized as suboptimal morphologic response. Patients who presented optimal morphologic response showed significantly longer progression-free survival compared with those presented suboptimal response (median, 4.9 months vs. 0.7 months; P = 0.028), while size-based response evaluation could not well stratify patient prognosis.
conclusionNon-size-based CT morphologic response could be a potential alternative response marker for patients treated with regorafenib.
