title: Phase I/II trial of preoperative oxaliplatin, docetaxel, and capecitabine with concurrent radiation therapy in localized carcinoma of the esophagus or gastroesophageal junction.
abstract: OBJECTIVE
  Preoperative chemoradiotherapy is a primary treatment option for patients with resectable esophageal cancer. Combination regimens using newer agents may improve patient outcomes. This multicenter community-based phase I/II trial examined a modern triplet regimen comprised of oxaliplatin, docetaxel, and capecitabine (ODC) combined with radiation therapy (RT).
  
  
  METHODS
  The primary end point was the pathologic complete response (pCR) rate. Eligibility criteria included resectable stage I to III cancer of the mid-/distal-esophagus or gastroesophageal junction, measurable disease, and Eastern Cooperative Oncology Group performance status (ECOG PS) of 0 or 1. Treatment included oxaliplatin 40 mg/m(2), docetaxel 20 mg/m(2) (intravenous, weekly x 5); capecitabine 1,000 mg/m(2) orally twice daily on days 1 to 7, 15 to 21, and 29 to 35; and concurrent RT (45 Gy). Resection was performed during weeks 9 to 12. ODC and RT safety was determined in a phase I portion (n = 10) preceding phase II.
  
  
  RESULTS
  Fifty-nine patients were enrolled (September 2005 to February 2008; phase I/cohort 1, 10 patients; phase I/cohort 2/phase II, 49 patients). Baseline characteristics included median age of 63 years; 84% male; ECOG PS 0 and 1, 51% and 49%, respectively; adenocarcinoma and squamous cell, 69% and 18%, respectively; stage I, II, and III, 12%, 41%, and 45%, respectively. Phase I revealed no dose-limiting toxicity. Responses: pCR rate, 49%; objective response rate, 61% (24 complete and six partial responses); stable disease, 6%; and progressive disease, 2%. Sixty-nine percent of patients underwent surgery. Survival: median follow-up, 116 weeks; median disease-free survival (DFS) and overall survival (OS) were 16.3 and 24.1 months, respectively. Two-year DFS and OS were 45.1% and 52.2%, respectively. Most common (>or= 5%) grade 3 to 4 nonhematologic toxicities were anorexia (20%), dehydration (16%), diarrhea (8%), dysphagia (10%), esophagitis (20%), fatigue (12%), hyperglycemia (6%), nausea (16%), pulmonary symptoms (14%), sepsis (6%), and vomiting (16%). All other grade 3 to 4 hematologic and nonhematologic toxicities were uncommon (< 5%).
  
  
  CONCLUSIONS
  Preoperative ODC plus RT is active and relatively safe in patients with locoregional esophageal cancer. Importantly, this therapy can be administered within 8 weeks. This regimen warrants additional study in this setting and in combination with newer biologic agents.
