title: Preoperative combined modality therapy with paclitaxel, carboplatin, prolonged infusion 5-fluorouracil, and radiation therapy in localized esophageal cancer: preliminary results of a Minnie Pearl Cancer Research Network phase II trial.
abstract: OBJECTIVE
  To evaluate the feasibility, toxicity, and therapeutic efficacy of 1-hour paclitaxel, carboplatin, continuous low-dose infusional 5-fluorouracil, and concurrent radiation therapy administered preoperatively in patients with localized esophageal cancer.
  
  
  METHODS
  Forty-nine patients with localized esophageal cancer, of either squamous cell carcinoma or adenocarcinoma histology, were enrolled into this phase II trial. All patients were candidates for surgical resection and received the following neoadjuvant therapy: paclitaxel, 200 mg/m2, 1 hour IV on days 1 and 22; carboplatin, AUC 6.0, IV on days 1 and 22; 5-fluorouracil, 225 mg/m2/day, continuous IV infusion on days 1 to 42; and radiation therapy, 45 Gy, administered by 1.8-Gy daily fractions beginning on day 1 of chemotherapy. Upon completion of this neoadjuvant regimen, patients were reevaluated, and all responding patients were resected within 6 weeks of completing neoadjuvant treatment.
  
  
  RESULTS
  Administration of this combined modality regimen was associated with moderate toxicity and was tolerated by most patients. Leukopenia (65%) and esophagitis (31%) were the most common toxicities. Most patients did not require nutritional support. There were no treatment-related deaths during neoadjuvant therapy; however, three patients (9%) experienced postoperative death. Preliminary assessment of treatment efficacy is encouraging, with 17 of 37 evaluable patients (46%) achieving pathologic complete remission and an additional 11 patients (30%) having only microscopic residual disease.
  
  
  CONCLUSIONS
  This novel, combined-modality neoadjuvant approach for the treatment of localized esophageal carcinoma is feasible and can be administered with toxicity that compares favorably to previously reported neoadjuvant regimens containing high-dose cisplatin. Preliminary assessment of efficacy is also encouraging, with 46% of patients having pathologic complete response. Further follow-up and larger numbers of patients are required to assess efficacy more definitively.
