Tissue carcinoembryonic antigen, calcium, copper and iron levels in cancerous lung patients.

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
BACKGROUND AND
objectiveThe expression of various trace elements and markers in lung cancer is controversial. The aim of this study is to evaluate the presence of calcium (Ca), copper (Cu), iron (Fe) and carcinoembryonic antigen (CEA) in cancerous untreated lung tissues and to determine a possible association between these markers and lung cancer.
methodsFourty-eight cancerous lung tissue blocks, from Sultan Qaboos University Hospital, Sultanate of Oman, were studied. Fe, Ca, Cu, and CEA were demonstrated in the tissue blocks using Perl's Prussian blue, Von Kossa's, modified rhodanine and immunohistochemical staining methods, respectively.
resultsTwenty-three of 48 specimens showed positive Fe staining, 2 showed positive Ca staining and Cu was absent in all specimens. 93.7% expressed CEA in varying degree of positivity. 81.25% of these sections showed high expression of CEA.
conclusionsTissue concentrations of trace elements were not elevated in lung cancer and therefore cannot be considered as a potential marker. Despite the low sensitivity and specificity of CEA as previously reported, tissue CEA should be considered as a potential marker in the evaluation of lung cancer.
