Unwarranted imaging for distant metastases in patients with newly diagnosed ductal carcinoma in situ and stage I and II breast cancer
Article in Canadian journal of surgery. Journal canadien de chirurgie, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Background: In 2012, the American Society of Clinical Oncology (ASCO) released a Choosing Wisely Top Five list that included a recommendation against ordering advanced imaging tests to screen for metastases among asymptomatic patients with early breast cancer. Our provincial breast cancer staging guideline was subsequently updated. We report on the use of unwarranted bone scanning (BS), computed tomography (CT), nonbreast magnetic resonance imaging (MRI) and positron emission tomography (PET) among women diagnosed with stage 0–II breast cancer in Alberta in 2011–2015. Methods: The cohort was retrospectively ascertained from the Alberta Cancer Registry. We used additional provincial data sources to obtain information about diagnostic imaging tests completed from biopsy to surgical date plus 4 months. The reason for each BS, CT, MRI and PET was abstracted. We calculated the frequency of advanced imaging tests completed for routine metastatic screening. Results: Of 10 142 patients included, 2887 (28.5%) had at least 1 advanced imaging test completed for routine metastatic screening. Of these 2887 patients, 438 (15.2%) had a follow-up BS, CT, MRI or PET, and 28 patients (1.0%) had a nonbreast imageguided biopsy. Use of routine advanced imaging tests did not change clearly over time. Conclusion: Our results demonstrate persistent use of advanced imaging tests for routine metastatic screening among patients with stage 0–II breast cancer despite the release of the ASCO Choosing Wisely recommendations and the update of our provincial breast cancer staging guideline. Investigation of strategies for guideline translation to improve upon value-based care of patients with early breast cancer is warranted.
