Nuclear and flow cytometric characteristics associated with overexpression of the c-erbB-2 oncoprotein in breast carcinoma.

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
The overexpression of the c-erbB-2 oncoprotein is now thought by most authors to be associated with adverse prognosis in breast carcinoma. In this study, we investigate the relationship between overexpression of the c-erbB-2 oncoprotein and nuclear size by morphometry in a series of 150 human breast carcinomas, comprising 65 cases of ductal carcinoma in situ (DCIS) and 85 cases of invasive adenocarcinoma. The mean nuclear size for c-erbB-2 positive cases of DCIS was 54.8 micron 2 and invasive carcinoma was 52.1 micron 2 respectively, in contrast with 41.6 micron 2 and 42.5 micron 2 for c-erbB-2 negative cases of DCIS and invasive carcinoma respectively. Flow cytometric examination of DNA in a subset of 91 of these tumours showed no association between tumour cell aneuploidy and c-erbB-2 overexpression. S-phase fraction could be calculated on 20 cases of DCIS and 48 invasive carcinomas. There was a strong association between c-erbB-2 overexpression, S-phase fraction (p less than 0.001) and proliferative index (p less than 0.001) in 20 cases of DCIS. A weak association of S-phase fraction and c-erbB-2 overexpression was seen in 48 invasive carcinomas (p = 0.047). This study confirms the subjective impression that there is a relationship between large tumour cell nuclear size and an overexpression of the c-erbB-2 oncoprotein, and also shows an association with increased tumour cell proliferation.
