Expression of cell adhesion molecules in laryngeal carcinoma - preliminary analysis.
Article in Contemporary oncology (Poznan, Poland), 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aim of the studyIntercellular adhesion molecules present in immunocompetent cells as well as endothelium and tumour cells can regulate cell migration, angiogenesis, apoptosis, proliferation, and metastases in solid tumours. The aim of this study was to analyse the sICAM-1 (soluble intercellular adhesion molecule 1) and sVCAM-1 (soluble vascular cell adhesion molecule 1) expression in peripheral blood mononuclear cell (PBMC) cultures, and to find their relationships with clinicomorphological characteristics in laryngeal cancer. MATERIALS AND
methodsThe analysis included a group of 50 patients with verified squamous cell carcinoma of the larynx. The control group constituted 30 healthy volunteers. The pathological assessment included pTNM, stage, histological grade, and type of invasion according to the tumour front grading. The expression of adhesion molecules was assessed using the enzyme-linked immunosorbent assay (ELISA).
resultsIncreased expression of sICAM-1 and sVCAM-1 was an indicator of more aggressive laryngeal carcinomas. More advanced local changes evaluated on the pT feature were connected with a higher sVCAM-1 (p = 0.017), but not sICAM-1 level. The presence of lymph node metastases correlated with a higher expression of adhesion molecules (p = 0.012 and p = 0.003, for sICAM-1 and sVCAM-1, respectively). Tumours with more diffuse growth and infiltrating with small cell groups (< 15/hpf) was characterised by the highest level of adhesive proteins (p = 0.001 and p = 0.02 for sICAM and sVCAM, respectively). Moreover, lower levels of sICAM-1 and sVCAM-1 were observed more frequently in patients who lived longer than five years after treatment.
conclusionsThe study indicates the importance of the sICAM and sVCAM expression as indicators of advanced changes and prognosis in patients with laryngeal carcinoma.
