Expression of CD44v6 and RCAS1 in Uterine Cervical Carcinoma Infected with Human Papillomavirus and Its Effect on Cell Proliferation and Differentiation.

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 investigate the expression of CD44v6 and RCAS1 and the presence of HPV in cervical cancer tissues, to determine serum RCAS1 levels, and to evaluate these components in correlation with clinicopathologic features and survival.
methodsA total of 52 patients consisting of 28 squamous cell carcinoma (SCC) and 24 adenocarcinoma cases, were studied. RCAS1 and CD44v6 expression was evaluated using immunohistochemical staining. HPV 16 and 18 E6 genes were detected using PCR, and serum RCAS1 concentrations were measured using ELISA. Associations between these factors and clinicopathologic features and survival were analyzed.
resultsCD44v6 expression was significantly higher in SCC compared with that in adenocarcinoma (P<0.001). It also showed a significant relation to histologic grade (P<0.001) and tumor size (P=0.03). RCAS1 expression was higher in adenocarcinoma than in SCC (P=0.001), and it showed a borderline relation with histological grade (P=0.057). Overall survival was not significantly different in both CD44v6 and RCAS1 expression; however, FIGO stage (P=0.025) and tumor size (P=0.042) resulted statistically different. The pre-surgical treatment serum RCAS1 levels were not associated with any clinicopathological variables. The presence of HPV 16 E6 was higher in SCC, while the presence of HPV 18 E6 was higher in adenocarcinoma (P<0.001). Detection of HPV 16 E6 was significantly associated with expression of CD44v6. The presence of HPV both HPV 16 E6 and HPV 18 E6 was found in cancer tissues with RCAS1 expression, but without any statistical significance.
conclusionCD44v6 and RCAS1 expression seems to be involved in tumor proliferation and differentiation, but it is not implicated in the progression and invasion of cervical cancer infected by HPV. Pre-treatment levels of serum RCAS1 in cervical cancer are not a diagnostic and predictive biomarker.
