PURPOSE
This multicenter phase IB/II trial investigated cetuximab added to preoperative chemoradiotherapy for esophageal cancer.
PATIENTS AND METHODS
Patients with resectable, locally advanced esophageal cancer received two 3-week cycles of induction chemoimmunotherapy (cisplatin 75 mg/m(2) day 1, docetaxel 75 mg/m(2) day 1, cetuximab 250 mg/m(2) days 1, 8,15 [400 mg/m(2) loading dose]) followed by chemoimmunoradiation therapy (CIRT) and surgery. CIRT consisted of 45 Gy radiotherapy (RT) plus concurrent cisplatin 25 mg/m(2) and cetuximab 250 mg/m(2) weekly for 5 weeks in cohort 1. If fewer than three of seven patients experienced limiting toxicity (LT), the next seven patients also received docetaxel (20 mg/m(2) weekly × 5). If fewer than three patients experienced LTs, 13 additional patients were treated at this dose.
RESULTS
In total, 28 patients (median age, 64 years) with predominantly node-positive (82%) esophageal adenocarcinoma (15 patients) or squamous cell carcinoma (13 patients) were enrolled and 24 (86%) completed the entire trimodal therapy. During CIRT, no LT occurred, rash was not exacerbated within the RT field, and the main grade 3 toxicities were esophagitis (seven patients), anorexia (three), fatigue (three), and thrombosis (two). Surgery (R0 resection) was performed in 25 patients. Anastomotic leakage occurred in three patients: two recovered spontaneously and one successfully underwent re-operation. There were no deaths at 30 days and no treatment-related mortality after 12 months. Nineteen patients (68%) showed complete or near complete pathologic regression.
CONCLUSION
Adding cetuximab to preoperative chemoradiotherapy is feasible without increasing postoperative mortality. Phase III investigation has begun based on the high histopathologic response and R0 resection rate.
