Prognostic significance of syndecan-1 expression in squamous cell carcinoma of the tonsil.
Article in International journal of clinical oncology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
backgroundSyndecan-1 (SDC1) is reported to modulate several key processes of tumorigenesis and to show variable expression in many cancers. The cause of these variations in expression is not known to date. In this study, we compared SDC1 status with clinicopathologic parameters to evaluate the prognostic implications of SDC1 status on squamous cell carcinoma (SCC) of the tonsil.
methodsIn 56 cases of tonsillar SCC, we screened SDC1 expression using immunohistochemistry and analyzed the relationships between SDC1 expression and clinicopathological parameters. To identify the cause of the changes in SDC1 expression seen in tumors, we measured the gene dosage of SDC1 in tumor cells using fluorescent in situ hybridization.
resultsSDC1 expression was found in cancer cells in 36 cases (64.3 %) of tonsillar SCC. It was associated with lymph node metastasis (p = 0.010) and a positive surgical resection margin (p = 0.014). On the other hand, it was not significantly correlated with sex, age, smoking status, degree of differentiation, T stage, or distant metastasis. We could not find any copy-number variation of SDC1 in the cases showing increased SDC1 immunopositivity. In addition, strong SDC1 expression in the tumor cells predicted a shorter overall survival (p = 0.020, log-rank).
conclusionsWe showed that SDC1 expression is associated with N stage and the status of resection margin involvement in SCC of the tonsil. With respect to survival, there were unfavorable outcomes in cases with SDC1 positivity. More studies are needed to better understand the role of SDC1 in the progression and invasiveness of tonsillar SCC.
