Methods: From January 2005 to December 2008, 605 patients who underwent radical surgery in The First Affiliated Hospital of Nanjing Medical University were enrolled. We conducted the follow-up every 6 months and its contents included a comprehensive medical history, tumor markers and abdominal ultrasound or CT and other imaging findings. Deadline was April 30, 2013 and follow-up time between 51 to 91 months. Survival time is calculated from the date of diagnosis to death or last follow-up date. Immunohistochemistry (IHC) was used to assess the expression of ERCCI in resected samples. The relationship between ERCCI expression and survival of patients was investigated. The comparison of count data were analyzed by Chi-square test. Median survival time (MST) and the 5-year survival rate were calculated by life table analysis. The Kaplan-Meier curves were used for survival analysis. Results: ERCC1 expression was positive in 412 patients (68.1%). There is no significant difference between ERCCl-positive group and ERCCl-negative group in terms of the MST and 5-year survival rate (P=0.455). The MST and 5-year survival rate have no significant difference (P=0.162) between group with chemotherapy and group with no chemotherapy in patients with ERCCl-positive expression. However, the MST and 5-year survival rate in patients with ERCCl-negative expression benefited more from with chemotherapy (P=0.019). The ERCCl-positive patients survived longer than those ERCCl-negative patients (P=0.183) in subgroup with no adjuvant chemotherapy. In the subgroup analysis, ERCC 1 expression had no significant relationship with overall survival in patients with stage II or llI gastric cancer (P〉0.05). Conclusions: ERCC1 might be a good prognostic factor for the patients of gastric cancer after radical resection. Patients with ERCCl-negative expression could benefit more from adjuvant chemotherapy.展开更多

Methods: ERCC1 Asn 118Asn polymorphism was analyzed in 99 patients with stages Ⅲ and Ⅳ advanced colorectal cancer treated with oxaliplatin-based chemotherapy, For all of the patients, ERCC1 Asnl18Asn genotype was analyzed for associations with treatment response and time to disease progress (TTP). Results: The allele frequencies of the ERCC1 gene codon 118 were C/C 50.51% (50/99), C/T 41.41% (41/99), T/T 8.08% (8/99), respectively. Patients with C/C genotype showed higher response rate than those with C/T + T/T (OR = 3.764, 95% CI: 1.310-10.813). The median TTP of all patients was 7 months (95% CI: 5.569--8.431). Patients with C/C genotype showed a median TTP of 10 months (95% CI: 8.924-11.076), which was longer than 5 months (95% CI: 4.424-5.576) in patients with C/T + T/T genotypes. Conclusion: Our results showed a link between ERCC1 Asn118Asn genetic polymorphism and cancer response to oxaliplatin-based chemotherapy and time to disease progress in Chinese patients with advanced colorectal cancer. ERCC1 Asn 118Asn genotyping may be of predictive benefit in selecting treatment regimen for advanced colorectal cancer.展开更多
