Simultaneous Integrated Boost Radiotherapy and Concurrent Nimotuzumab or Chemotherapy for Esophageal Carcinoma

Phase 2
Conditions
Esophageal Neoplasms
Interventions
Radiation: IMRT simultaneous integrated boost
Procedure: Esophagectomy
Registration Number
NCT02858206
Lead Sponsor
Chinese Academy of Medical Sciences
Brief Summary

This prospective, non-randomized phase II study aims to compare radiotherapy and concurrent nimotuzumab with concurrent chemoradiotherapy to obtain a non-inferior pCR rate and pathological lymph node metastases rate in premise of lower toxicities in locally advanced esophageal cancer.

Detailed Description

In the era of IMRT and concurrent chemoradiotherapy, the 5-year overall survival of esophageal cancer increase from 10% to about 20%-40%, recurrence rate decrease from 80% to 50%-60%, and local recurrence remains to be the most important type of failure. What called for is to enhance local control without increasing toxicity to improve survival. The investigators have found effective and safe regimen of simultaneously integrated boost radiotherapy in previous study, which can achieve high dose in tumor area with avoid of normal tissues. However, a recent prospective study reported that neoadjuvant chemoradiotherapy resulted in much higher toxicities compares to neoadjuvant chemotherapy (46% vs. 15%, p= 0.04). Although chemoradiotherapy reached a higher pCR rate (28% vs. 9%, p=0.002), patients did not differ in survival in two groups.

Nimotuzumab is an humanized monoclonal antibody against EGFR. Radiotherapy combines Nimotuzumab reveals synergistic effect in head and neck cancers with lower toxicities as compared to concurrent chemoradiotherapy. Our previous study showed that EGFR expression rate were similar in esophageal cancer and head and neck cancers. Based on above results, the investigators design this study which aims to obtain a non-inferior pCR rate and pathological lymph node metastases rate in premise of lower toxicities.

Radical nimotuzumabIMRT simultaneous integrated boostRadiation:Patients undergo radiotherapy once daily 5 days a week for an average of 5.5 weeks in the absence of disease progression or unacceptable toxicity. IMRT simultaneous integrated boost is used to achieve a prophylactic dosage and radical dosage of 1.8Gy and 2.14Gy once respectively. Concurrent nimotuzumab: Patients may receive nimotuzumab 400mg per week which start from 1 week before radiotherapy and in the following 4 weeks after enrollment in the absence of disease progression or unacceptable toxicity.
Neoadjuvant chemotherapyIMRT simultaneous integrated boostRadiation:Patients undergo radiotherapy once daily 5 days a week for an average of 4.5 weeks in the absence of disease progression or unacceptable toxicity. IMRT simultaneous integrated boost is used to achieve a prophylactic dosage and radical dosage of 1.8Gy and 2.14Gy once respectively. Concurrent chemotherapy: Patients may receive a dosage range of Paclitaxel from 45 to 60 mg/m2 and Nedaplatin 25mg/m2 per week which start from 1 week before radiotherapy and in the following 4 weeks after enrollment in the absence of disease progression or unacceptable toxicity. Assessment of surgery: Patients eligible for surgery after multiple disciplinary consultation will receive esophagectomy after a 4-6 weeks break after chemoradiation in the absence of any contraindication.
