title: Modified biweekly oxaliplatin and capecitabine for advanced gastric cancer: a retrospective analysis from a medical center.
abstract: BACKGROUND
  We modified 3-week XELOX regimen with oxaliplatin to 85 mg/m 2 on Day 1 and capecitabine 1000 mg/m 2 BID for 10 days every 14 days to be more practical in clinical practice for advanced gastric cancer. The aim of this retrospective analysis is to evaluate the safety profile and efficacy of the modified oxaliplatin plus capecitabine (XELOX) regimen as the first-line treatment for patients with advanced gastric cancer in a medical center in Taiwan.
  
  
  METHODS
  From March 2009 to December 2010, among the 614 patients diagnosed with gastric cancer in a medical center, 49 patients with unresectable advanced or metastatic gastric adenocarcinoma were treated with oxaliplatin (85 mg/m 2 ) on Day 1 and capecitabine (1000 mg/m 2 BID) for 10 days every 2 weeks (mXELOX). CT scan was performed for tumor response evaluation. Clinical outcome and adverse events after mXELOX treatment were analyzed retrospectively.
  
  
  RESULTS
  A total of 354 mXELOX sessions (median: 6) were administered in 49 patients. The overall tumor response rate was 39.1% among 46 evaluated patients: three complete response (6.5%) and 15 partial response (32.6%). Seven patients had stable disease (15.2%) and 21 (45.7%) patients had progressive disease. The median progression-free survival and median overall survival were 4.37 months and 12.26 months, respectively. The most common grade III/IV hematologic toxicity was anemia (10.2%), and non-hematologic toxicity effects were numbness (8.2%), hand-foot syndrome (10.2%), diarrhea (6.1%), thrombocytopenia (6.1%), and abdominal pain (6.1%).
  
  
  CONCLUSIONS
  This modified biweekly oxaliplatin and capecitabine combination chemotherapy is practical and effective for unresectable advanced or metastatic gastric cancer in our daily practice.
