Summary
Brief summary (as posted)
This is a single arm phase II trial with combined celecoxib, tegafur-uracil, folinate and preoperative radiotherapy for patients with locally advanced rectal cancer. The primary end point is pathological complete response (pCR) rate. The secondary endpoints are toxicities of combined celecoxib and chemoradiation, negative resection margin rate, clinical tumor response by magnetic resonance imaging (MRI), sphincter preservation rate, disease-free survival and overall survival.

Biopsy proven adenocarcinoma, superior margin of the tumor below the L5-S1 spine junction. 6. WBC \> 3.5 x109/L, neutrophil count \> 1.5x109/L, platelet count \> 100x109/L, serum bilirubin \< 1.25xULN (upper limit of normal), AST/ALT \< 3x ULN, serum creatinine \< 1.25xULN. 7. Informed consent signed. Exclusion Criteria: 1. Distant metastasis, Prior pelvic irradiation, Inflammatory bowel disease, Medical conditions which preclude radical therapy. 2. History of malignancy within five years (except nonmelanoma skin cancer, CIN cervix). 3. Pregnancy. 4. Hypersensitivity to celecoxib, NSAID, sulfonamides or 5-FU. 5. Cardiovascular disease like congestive heart failure, symptomatic coronary artery disease, or myocardiac infarction. 6. History of peptic ulcer disease or NSAID-related gastrointestinal bleeding 7.
