Is vimentin a potential prognostic factor for patients with triple-negative breast cancer?
Article in Journal of cancer research and clinical oncology, 2020. 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
objectiveTo evaluate the prognostic potential of vimentin, p53, EGFR, CK5/6, CK 14, and CK 17 in patients with triple-negative breast cancer (TNBC). MATERIAL AND
methodsTumor specimens of 60 patients with histologically confirmed TNBC were retrospectively analyzed. Formalin-fixed paraffin-embedded blocks of the tumor tissue were used to prepare tissue microarrays (TMAs). After immune-histochemical staining, protein expression of vimentin, p53, EGFR, CK5/6, CK 14, and CK 17 was determined and the immunoreactive score (IRS) was calculated. The protein expression was correlated to overall (OS) and disease-free survival (DFS).
resultsNinety percent of patients suffered from an invasive ductal carcinoma T1 or T2, 66.7% were N0, and 70% had a G3 tumor with Ki67 of > 14%. Vimentin expression was found in 28/60 patients (46.7%), p53 expression in 30/60 patients (50%), and EGFR expression in 3/60 patients (5%). CK5/6, CK14, and CK17 expression was found in 60.0%, 63.3%, and 66.7%, respectively. Vimentin expression vs no expression was associated with significantly higher mean Ki67 values (52.5% vs. 31.1%; p = 0.0013) and significantly higher p53 expression (67.9% vs. 34.4%; p = 0.0097). No significant association between vimentin expression and OS (p = 0.7710) or DFS (p = 0.5558) was found during a mean follow-up of 92 months.
conclusionNone of the six proteins proved to be suitable prognostic factors for OS and DSF in patients with TNBC.
