Drosha Rs10719 T > C Is Associated With Lymph Node Metastasis And Clinical Stage Of Gastric Cancer Patients
INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY(2017)
摘要
It has been proved that polymorphisms in DROSHA are related to the risk and outcomes of several cancers. In our study, 97 patients with stage I-III gastric cancer treated with radical gastrectomy and adjuvant chemotherapy of oxaliplatin and fluoropyrimidines were analyzed. MassARRAY MALDI-TOF system was used to determine the genotypes. The 2-year DFS rate was 60.8% and the 3-year OS rate was 73.8%. In dominant model, we found that rs10719 TC+CC genotype carriers were less likely to develop lymph node metastasis (P=0.031). Compared with TC+CC genotype carriers, more patients with TT genotype were in stage III (P=0.021). The 3-year OS was significantly different for patients with or without lymph node metastasis (89.3% vs 63.3%, P=0.013) and for patients with stage I-III disease (100.0%, 88.6% and 55.8%, P=0.015). After the multi-variants' cox regression analysis, lymph node status (P=0.014, RR: 9.556, 95% CI: 1.586-57.590) was found to be an independent prognostic factor for these patients. These results suggested that DROSHA rs10719 T > C may be associated with lymph node metastasis and clinical stage of gastric cancer in a Chinese population.
