Prognostic role of immune environment in luminal B early breast cancer.
Article in Cancer medicine, 2023. 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
The importance of the immune microenvironment in triple negative and HER2-amplified breast cancer (BC) is well-established; less is known about the immune environment in luminal breast cancers. We aimed to assess for the impact of immune biomarkers on BC outcome in a group of luminal B patients with archived tissue and annotated clinical information. Patients with early breast cancer (EBC) treated in a single institution over a 14-year period, with prospectively collected data were included. Luminal B EBC patients were identified and defined into three cohorts: A: grade 2 or 3, ER & PR positive, HER2-negative; B: Any grade, ER positive, PR and HER2-negative (Ki67 ≥ 14% in cohorts A & B); and C: Any grade, ER or PR positive, HER2-positive. Within each cohort, patients with a relapsed BC event (R) were compared on a 1:1 basis with a control patient (C) who remained disease-free, balanced for key characteristics in an effort to balance the contribution of each clinical group to outcome. Archival breast, involved and uninvolved axillary nodes were assessed by immunohistochemistry for biomarkers identifying effector and suppressor immune cells, and compared between R and C. In total, 120 patients were included (80, 22, and 18 patients in cohorts A, B, and C, respectively). R were 1.5 years older (p = 0.016), with all other characteristics being balanced. Overall, there were no statistically significant differences in immune biomarkers in breast or nodal tissue of R and C. However, there was a trend toward higher levels of TILs in breast tumors of C, while GAL-9 was consistently expressed on lymphocytes and tumor cells in all breast and nodes of C and was absent from all tissues of R. These trends in checkpoint molecule expression deserve further research.
