Loss of heterozygosity analysis of microsatellites on multiple chromosome regions in dysplasia and squamous cell carcinoma of the esophagus.
Article in Experimental and therapeutic medicine, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The objective of this study was to characterize the molecular events in the carcinogenesis of esophageal squamous cell carcinoma (ESCC) and to identify biomarkers for early detection of the disease. Matched precancerous and cancerous tissues resected from 34 esophageal cancer patients from Chongqing, southern China, were compared to evaluate the extent of loss of heterozygosity (LOH). Sixteen microsatellite markers on chromosome regions 3p, 4p, 5q, 8p, 9p, 9q, 11p, 13q and 17p were used for PCR-based LOH analysis. The overall frequency of LOH at the 16 microsatellite loci was significantly increased as the pathological status of the resection specimens changed from low-grade dysplasia (LGD) to high-grade dysplasia (HGD) and SCC (P<0.001). A total of 8 markers showed LOH in the LGD samples. In addition, heterozygosity was regained at 4 loci in the SCC samples of 4 patients, respectively, in comparison to the results for these loci in the HGD samples. The overall rate of LOH increased significantly with the deterioration of the lesions, indicating that tumorigenesis of the esophageal squamous epithelia is a progressive process involving accumulative changes in LOH. The 8 loci showing allelic loss in the LGD samples may be involved in the early-stage tumorigenesis of ESCC, and LOH analysis at these loci may help improve the early detection of this disease. Regain of heterozygosity found in certain patients suggests the possibility of genetic heterogeneity in the tumori-genesis of esophageal cancer.
