Possible prognostic value of BORIS transcript variants ratio in laryngeal squamous cell carcinomas - a pilot study.
Article in Pathology oncology research : POR, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
BORIS is a paralog of a highly conserved, multi-functional chromatin factor CTCF. Unlike CTCF, which has been shown to possess tumor-suppressive properties, BORIS belongs to the "cancer/testis antigen" family normally expressed only in germ cells and aberrantly activated in a variety of tumors. The consequences of BORIS expression, relative abundance of its isoforms, and its role in carcinogenesis have not been completely elucidated. It activates transcription of hTERT and MYC, genes relevant for laryngeal carcinoma progression. In this study, BORIS expression has been analyzed at the transcriptional level by RT-PCR and protein level by semi-quantitative immunohistochemistry in 32 laryngeal squamous cell carcinomas and adjacent non-tumorous tissue. BORIS was detected in 44 % (14/32) laryngeal squamous cell carcinoma samples, while it was detected only in one normal, tumor-adjacent tissue sample. Tree based survival analysis, using the recursive partitioning algorithm mvpart, extracted the ratio of relative abundance of BORIS transcript variants containing exon 7 (BORIS 7+) and those lacking exon 7 (BORIS 7-) as an independent prognostic factor associated with disease relapse during a 5-year follow-up period. Patients having BORIS 7+/BORIS 7- ratio ≥1 had a higher rate of disease relapse than patients with BORIS 7+/BORIS 7- ratio <1. Hazard ratio for that group, based on Cox Proportional Hazard Regression, was 3.53. This is the first study analyzing expression of BORIS protein and transcript variants in laryngeal squamous cell carcinoma relative to its possible prognostic value for recurrence and overall survival.
