A Case in Which Breast Cancer Developed at the Same Time As Dermatomyositis, and the Onset of New Cancer Was Able to Be Predicted by the Exacerbating Skin Symptoms and Parallel Increase in the Anti-TIF1-γ Antibody Levels.

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
Dermatomyositis (DM) is an idiopathic inflammatory myopathy. The incidence of malignancy in DM patients is quite high. Anti-transcription intermediary factor 1-γ (anti-TIF1-γ) antibody is more prevalent in DM patients with malignancy than in those without malignancy. A 70-year-old woman developed hoarseness and difficulty swallowing. A physical examination revealed skin abnormalities. Breast cancer was found in her right breast. She was positive for anti-TIF1-γ antibody. Chemotherapy reduced the tumor size, decreased the anti-TIF1-γ antibody level, and improved her symptoms. About 2.5 years later, however, her skin symptoms worsened, and anti-TIF1-γ antibody levels increased again, and colorectal cancer was found. Treatment with endoscopic mucosal resection (EMR) improved her symptoms again. Our case suggests that the exacerbating skin symptoms and parallel increase in the anti-TIF1-γ antibody level led to the detection of a second cancer after treatment of the first cancer in this case of DM.
