Survival is associated with genetic variation in inflammatory pathway genes among patients with resected and unresected pancreatic cancer.
Article in Annals of surgery, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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 test whether or not the association between inflammation and pancreatic ductal adenocarcinoma (PC) is facilitated by host susceptibility, specifically by genetic polymorphisms in inflammation-related genes. SUMMARY BACKGROUND DATA: Inflammation has been linked to PC. Reports have cited an increased expression of proinflammatory mediators, such as NF-κB and COX, in PC but not in normal adjacent tissue, suggesting a possible role in carcinogenesis. We sought to further understand the role that genetic variants in the NF-κB inflammatory pathway play in the development and progression of PC.
methodsWe genotyped 1536 tag single nucleotide polymorphisms (SNPs) in 102 candidate genes of multiple inflammatory pathways in 1308 white patients with PC who were divided into 3 groups on the basis of the extent of disease: resected for cure (n = 400), locally advanced/unresected (n = 443), and metastatic (n = 465). Survival analysis was performed using Kaplan-Meier curves and Cox proportional hazards regression models. Statistical significance was set at less than 0.001 to control for multiple testing.
resultsMedian age was 67 (28.0-91.0) years, and 57% were men. Median survival for each of the 3 groups (resected, locally advanced, and metastatic) was 23.7, 9.4, and 6.6 months, respectively (P < 0.0001). In the resected group, carriers of a minor allele for either rs3824872 (MAPK8IP1) or rs8064821 (SOCS3) were associated with a 10- and 6-month survival advantage compared with noncarriers in patients with resected disease, with an additional 2-year survival if both minor alleles were present. With locally advanced disease, SNP rs1124736 (IGF1R) was associated with improved survival if they had a copy of the G allele, hazard ratio of 0.57 (95% confidence interval: 0.42-0.77); P = 0.0002. In addition, 4 SNPs in patients with metastatic disease were found to be associated with worse survival and 2 associated with improved overall survival, but the differences in survival were deemed not clinically significant.
conclusionsSNPs in the inflammatory pathway genes MAPK8IP1 and SOCS3 were associated with increased overall survival in patients undergoing potentially curative resection and may be used in the future as markers to predict survival. Future research is needed to determine the functional relevance of these loci.
