Prognostic role of immunosuppressive acidic protein in patients with esophageal cancer

21047 Background: A single nucleotide polymorphism in the MDM2 promoter (SNP309) has been found to affect OS of advanced stage gastric adenocarcinoma (AD) and early stage squamous (SQ) cell carcinoma of the lung. The aim of this study was to evaluate the role of this polymorphism in the prognosis of esophageal cancer, another aerodigestive cancer. Methods: 150 early stage (E) and 118 locally advanced stage (LA) esophageal cancers were genotyped for MDM2 SNP309 using Taqman. The primary endpoint was overall survival (OS). Results: E disease: n=23 stage I; n=127 stage II. LA disease: n=93, Stage III; n=25, Stage IVA. AD comprised 215 (81%), while SQ comprised 45 (17%) of cases; 8 (3%) had poorly differentiated tumors. Median follow-up = 32 months. Median OS were 36 and 21 months for E and LA disease, respectively. Both histology and disease stage affected the relationship between SNP309 and esophageal cancer OS (see Table ). The wildtype T/T genotype conferred a worse OS in E patients (log-rank, p=0.03), especially those with AD (log-rank, p=0.003). In Cox proportional hazards interaction analyses, after adjusting for age, gender, stage and PS, there were statistically significant interactions between MDM2 SNP309 and disease stage (interaction p=0.004) and between MDM2 SNP309 and histologic subtype (AD vs. SQ)(interaction p=0.02). Thus, the direction of SNP309 association from our AD and E esophageal cancer patients are opposite to those of our SQ and LA esophageal cancer patients. However, our SQ and LA results are similar to the SQ lung cancer and advanced stage gastric cancers previously reported. This suggests that biologic mechanisms underpinning the prognostic role of SNP309 are dependent on extent of disease and histologic subtype. Conclusion: Histology and disease stage interact with the prognostic role of MDM2 SNP309 polymorphism in esophageal cancer OS. [Table: see text] No significant financial relationships to disclose.

Objectives.We performed this meta-analysis to summarize all the results from available studies, aiming delineating the prognostic role of miRNA in esophageal cancer.Design and Methods. We searched the electronic databases PubMed, EMBASE, and ISI Web of Science without time restrictions for the correlative literature to aggregate the survival results. Relevant data were extracted from studies investigating the relationship between miRNAs expression and survival in esophageal cancer patients. Pooled hazard ratios of miR-21and miR-375 for OS in ESCC were calculated.Results.A total of 25 studies involving 2,258 subjects analyzed the relationship between miRNA and prognosis of EC. In all, thirty-nine miRNAs associated with prognosis were reported in these studies. The pooled HR of higher miR-21 expression compared with lower miR-21 expression in ESCC was 1.84 (95% CI: 1.41–2.40,P<0.001), which could significantly predict poorer OS in ESCC. Besides, higher miR-375 was also a significant predictor for OS in ESCC, with a pooled HR of 0.55 (95% CI: 0.42–0.72,P<0.001).Conclusions.Our results support that miR-21 and miR-375 have a prognostic role in ESCC and may be useful therapeutic targets for the treatment of ESCC and meticulous follow-up for early detection of recurrence.

60 Background: Fibroblast growth factor receptor 4 (FGFR4) has been associated with increased risk, staging, and metastasis in several type of cancer. The purpose of this study was to evaluate the prognostic role of FGFR4 Gly388Arg polymorphism in esophageal cancer after chemoradiotherapy. Methods: Peripheral blood samples from 250 patients who were treated with chemoradiotherapy were used for this study. Patients were diagnosed as a stage of I in 12 (5%), II in 54 (21%), III in 115 (46%) and IV in 69 (28) patients. All of the patients were received chemotherapy using cisplatin and fluorouracil or docetaxel. Results: The overall response was 85%, with 21% complete response and 64% partial response. The overall survival (stage II, 34months; stage III, 23.3 months; stage IV, 19.3 months, p=0.005) and progression survival (stage II, 23.8 months; stage III, 12.8 months; stage IV, 9 months, p=0.001) was significantly improved according to stage. In FGFR4 genotypic analysis, 96 patients (38.6%) were homozygous for Gly388 allele, with 113 heterozygous (45.4%) and 40 (16.0) homozygous for Arg388 allele. There was no significant association between FGFR4 genotype and stage. However, Gly388 allele patients show better overall response rate (90.6%) than Arg388 carriers (82.4%, p=0.050). In early stage (I, II, n=66), Gly388 allele patients tendted to have a better OS (p=0.898) or PFS (p=0.597) than Arg388 carriers. However, in advanced stage (III, IV), the survival outcomes was similar between genotypes. Conclusions: Present study shows that FGFR4 Gly388 allele has a prognostic role in response after chemoradiotherapy in esophageal cancer. Especially in early stage of esophageal cancer, FGFR4 might have an important role in disease progression and survival outcomes. It suggests that the possibility of new therapeutic target for esophageal cancer treatment.
