摘要: Purpose Recently, a single-nucleotide polymorphism in the MDM2 promoter (SNP309) has been found to lower age of onset tumors and increase occurrence multiple primary Li-Fraumeni syndrome, accelerate development sporadic adult soft tissue sarcoma. The aim this study was determine whether SNP309 is associated with susceptibility gastric carcinoma its prognosis. Patients Methods In case-control including 438 controls 410 patients carcinoma, genotyped. Serum pepsinogens (PGs) I II were measured control subjects 253 cases selected from patients. Tumor immunostained p53 examined for mutations exons 5 8 using polymerase chain reaction–based single strand conformational analysis direct sequencing. Results risk overall (G/G) significantly increased when compared T carriers (P = .039), especially carcin...
