Characterisation of biomolecular profiles in primary high-grade prostate cancer treated by radical prostatectomy.
Article in Journal of cancer research and clinical oncology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeThe aim of this study was to compare the biomolecular profile of high-grade (HG) with low-grade (LG) prostate cancers matched by preoperative serum prostate-specific antigen (PSA) levels.
methodsFrom 2,560 patients undergoing radical prostatectomy for localised disease, 24 men with HG cancer (Gleason score > or =9) were eligible. Their clinical data were compared with those of 24 LG tumours (Gleason score < or =6), matched by PSA values. The expression of Ki-67, p53, Bcl-2, chromogranin A, alpha-catenin, and PSA were analysed and compared between both groups.
resultsThe expression of Ki-67 (P=0.031), p53 (P=0.008), Bcl-2 (P=0.002), and chromogranin A (P=0.042) were expressed significantly higher, and alpha-catenin (P=0.020) and PSA (P<0.001) significantly lower in HG tumours. Cancer volumes of HG and LG differed significantly (10.6 cm3 vs 5.3 cm3; P=0.006). Overall, cancer volume correlated with increased expression of p53 (r=0.52; P<0.001) and chromogranin A (r=0.46; P<0.001), and with decreased expression of PSA (r=0.41; P<0.004).
conclusionsAccording to our data, tumour grade is clearly associated with a change in the biomolecular profile, even between patients with similar serum PSA levels. As the prognosis of HG prostate cancer is poor, these tumours should be analysed by immunohistochemical staining to identify specific tumour features for an appropriate selection of adjuvant therapy.
