Concurrent Chemoradiotherapy With Docetaxel and Cisplatin in Esophageal Cancer
Study Details
Study Description
Brief Summary
This study is designed to determined the feasibility and safety in advanced esophageal cancer treated with docetaxel and cisplatin cocurrent chemoradiotherapy. The primary end points were clinical best response and response rate and secondary endpoints were progression free survival and overall survival.

Detailed Description
Chemotherapy can provide significant palliation of symptoms for patients with unresectable, locally advanced or metastatic esophageal cancer. Cisplatin and continuous infusion 5 FU, alone or combined with radiotherapy, is the most frequently used regimen. The response rate reported with cisplatin and 5 FU ranged from 35 to 40% ,whereas the 2-year survival rates of patients with locally advanced esophageal cancer ranged from 8 to 55%, with a mean 27%. Therefore, there is a need to test new combination, specifically in unresectable locally advanced esophageal patients, with the aim of increasing the pCR rate and survival. Cisplatin had been widely used as radiosensitizer and Docetaxel is different from that of cisplatin -5FU and and has proved to have an additive effect with cisplatin and supra-additive antitumor activity with fluorouracil in vitro and in murine models. To investigate the feasibility of combining concomitant radiation with docetaxel and cisplatin and assess the regimen's toxicity, locoregional control rate, and survival in patients with locally advanced or metastatic esophageal cancer.In this study, docetaxel 25mg/m2 is given with 500ml normal saline , as a 1hr infusion, on days 1,8 of every 3 weeks. Cisplatin75mg/m2 is given by intravenous infusion in 500 mL of 5% dextrose solution over 60 minutes on day 1 of every 3weeks.. Therapy will be repeated every 21 days. Radiation therapy (200cGy/day upto 5400 cGy) begin on the first day of week 1 over 6 weeks (concomitant chemoradiation therapy). When the investigators assume that standard treatment's response rate is 50% and the response of experimental treatment is 75% and use Simon's two-stage optimal design under the significance level of 5% and the power of 80%, the total sample size of 25 is at least required. For a total of 25 subjects, 11 will be accrued during stage 1 and 14 during stage 2. If 6 or fewer responses are observed during the first stage then the trial is stopped early. If 16 or fewer responses are observed by the end of the trial then no further investigation of the drug is warranted. If the investigators assumed that the drop out rate was 10%, number of subjects per treatment arm will be 28.

Outcome Measures
Primary Outcome Measures
- Response rate [4-6 weeks after completion of CRT]
Chest and abdominal CT and EGD were obtained to assess tumor status, 4 to 6 weeks after the completion of CRT. The patients who were documented on the CT scan and upper gastrofibroscopy as showing a complete response (CR) underwent positron emission tomography (PET)-CT. If the PET-CT showed no metabolic evidence of malignancy, we deemed the response to be a CR.
Secondary Outcome Measures
- progression free survival, overall survival and adverse events [every 3-6 months]
Tumor resection with extended en bloc lymphadenectomy was performed in operable patients approximately 4 to 8 weeks after treatment. Follow-up evaluation was performed every 3months for the first 2years, then every 6monhs for the next 3 years, then annually until patinet death or loss to follow-up. This included clinical examination, dysphagia score, assessment of late radiation toxicity and repeat CT scan of chest/ abdomen and EGD.
