Objective:Benefits of adjuvant treatment in pT1 N1 gastric cancer(GC)remain controversial.Additionally,an effective biomarker for early GC is the need of the hour.The prognostic and predictive roles of single patient classifier(SPC)were validated in stageⅡ/ⅢGC.In this study,we aimed to elucidate the role of SPC as a biomarker for pT1 N1 GC.Methods:The present retrospective biomarker study(NCT03485105)enrolled patients treated for pT1 N1 GC between 1996 and 2012 from two large hospitals(the Y cohort and S cohort).For SPC,mRNA expression of four classifier genes(GZMB,WARS,SFRP4 and CDX1)were evaluated by real-time reverse transcription-polymerase chain reaction assay.The SPC was revised targeting pT1 stages and the prognosis was stratified as high-and lowrisk group by the expression of SFRP4,a representative epithelial-mesenchymal transition marker.Results:SPC was evaluated in 875 patients(n=391 and 484 in the Y and S cohorts,respectively).Among 864 patients whose SPC result was available,41(4.7%)patients experience GC recurrence.According to revised SPC,254(29.4%)patients were classified as high risk[123(31.5%)and 131(27.1%)in the Y and S cohorts,respectively].The high risk was related to frequent recurrence in both Y and S cohort(log-rank P=0.023,P<0.001,respectively),while there was no difference by GZMB and WARS expression.Multivariable analyses of the overall-cohort confirmed the high risk of revised SPC as a significant prognostic factor[hazard ratio(HR):4.402(2.293-8.449),P<0.001]of GC.A significant difference was not detected by SPC in the prognosis of patients in the presence and absence of adjuvant treatment(log-rank P=0.670).Conclusions:The present study revealed the revised SPC as a prognostic biomarker of pT1 N1 GC and suggested the use of the revised SPC for early-stage GC as like stageⅡ/Ⅲ. 展开更多

We have synthesized water-stable polyaniline nanoparticles coated with tri- armed polyethylene glycol chains using a solvent-shift method and confirmed their colloidal size and aqueous solubility. Furthermore, we have demonstrated that the polyaniline nanoparticles can be doped with biological dopants to produce distinct color changes allowing the detection of live cancer cells. 展开更多
