Abstract:
Objective To assess the relationship between polymorphism of XRCC1 Arg194Trp Arg399Gln and ESCC TNM stage and regional lymph node metastasis. Methods PCR and PCR-RFLP were used to detect polymorphism of XRCC1 Arg194Trp and Arg399Gin. The results were analyzed and compared to TNM staging and regional lymph node metastasis. Results The XRCC1 194Arg/Trp and 399Arg/Arg wildtype in ESCC with metastasis is 32.3%, which is higher than 194Arg/Arg (20.0%, P=0.01). There was no remarkable difference between IIb-IV stage ESCC with lymph node metastasis and 0-IIa stage without metastasis. Conclusion The ESCC patients with 194 variability and 399 wildtype had high metastasis rate, XRCC1 Arg194Trp and Arg399Gln had relationship with ESCC TNM stage and lymph node metastasis. Both of them affected to prognosis of ESCC.
