DNA Repair Gene and MTHFR Gene Polymorphisms as Prognostic Markers in Locally Advanced Adenocarcinoma of the Esophagus or Stomach Treated with Cisplatin and 5-Fluorouracil-Based Neoadjuvant Chemotherapy

Background DNA repair plays an important role in chemoresistance to platinum-based therapy, and therefore polymorphisms in the genes may modulate therapeutic response. We assessed 12 polymorphisms in 7 DNA repair genes and 2 polymorphisms in the MTHFR gene for association with disease response and prognosis.
