Recently, a TA autoantibody assay named em EarlyCDT /em -Lung (against p53, NY-ESO-1, CAGE, GBU4-5, MAGE A4, SOX2 and Hu-D) authorized by the FDA has been clinically and analytically validated. in more than one study. Mmp-7: Matrix metallopeptidase 7; Hsp70: Warmth shock protein 70; PRDX 6: Peroxiredoxin 6; Bmi-1: BMI1 proto-oncogene, polycomb ring finger; Koc: Insulin-like growth element 2 mRNA binding protein 3; C-Myc: MYC proto-oncogene, bHLH transcription factor; IMP1: Insulin-like growth element 2 mRNA binding protein 1. Probably the most comprehensively investigated TA autoantibodies in ESCC have been p53 autoantibodies followed by autoantibodies against P16 and c-Myc. Given the prominent feature of p53 in cancers it is not unexpected that this is the most widely analyzed autoantibody in ESCC. Autoantibodies against p53 in the analysis of ESCC have been evaluated in 17 studies (Table ?(Table2),2), and the sensitivities vary largely between reports (7%-60%) while less variance is observed in the specificity (range 89.5%-100%, Table ?Table2).2). A meta-analysis by Zhang et al[39] showed the overall level of sensitivity and specificity of p53 autoantibody for esophageal malignancy are 29.6% and 97.9%, respectively. Autoantibodies against P16 and c-Myc were each analyzed in five studies, and both exhibited high specificity but poor Afegostat level of sensitivity (Table ?(Table2).2). Consequently, despite the high specificity, all studies show that use of a single autoantibody provides low level of sensitivity indicating limited medical software. The level of sensitivity and specificity for Hsp70 autoantibodies reported by Fujita et al[40] can be up to 93.7% and 100%, respectively. However, the very small sample size of this study reduces the stability and power of the results. Overall, quite apparent is the truth the diagnostic value of individual TA autoantibody biomarkers in ESCC is quite limited. DIAGNOSTIC PERFORMANCE OF Solitary AUTOANTIBODIES IN EGJA Very few medical or translational studies possess treated EGJA as a separate entity, which have been generally divided between those focusing on esophageal cancer and those targeting gastric malignancy. Likewise, a similar phenomenon has been observed in the studies on autoantibodies for the analysis of EGJA. As can be seen from Table ?Table3,3, a total of 13 autoantibodies were investigated in two studies[41,42], all of which were in the beginning Rabbit polyclonal to JAKMIP1 assessed in ESCC by Xu et al[43] and Zhou et al[44]. As anticipated, the presence of TA autoantibodies shows early diagnostic potential for EGJA. The level of sensitivity of solitary TA autoantibody biomarkers for EGJA ranged from 11.0% to 54.3% with generally high specificity ranging from 86.3% to 97% (Table ?(Table3).3). From your list of autoantibodies shown in Table ?Table3,3, there is no good way of forecasting which TA autoantibodies may work. Like ESCC, the most commonly tested Afegostat TA autoantibody in EGJA is the p53 autoantibody, which has the highest area under the curve value (0.799) with moderate sensitivity and specificity in the analysis of early stage EGJA (Table ?(Table3).3). However, it remains truth that the capability of a single TA autoantibody biomarker to identify EGJA patients is limited. It also should be pointed out that study on autoantibodies is still in its infancy. Therefore, Afegostat more autoantibody biomarkers need to be recognized and evaluated to enlarge the autoantibody pool for EGJA.
