RATIONALE: Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Cetuximab may also stop the growth of esophageal cancer by blocking blood flow to the tumor and by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cisplatin and irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving cetuximab together with combination chemotherapy and radiation therapy may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving cetuximab together with combination chemotherapy and radiation therapy works in treating patients with locally advanced esophageal cancer that cannot be removed by surgery.

Primary Outcome Measures:
  • Overall Survival at 2 Years [ Time Frame: 0-2 years ]
    Measured from time of registration to date of death due to any cause, or last contact date

Secondary Outcome Measures:
  • Number of Patients With Grade 3 Through 5 Adverse Events That Are Related to Study Drug [ Time Frame: Patients were assessed for adverse events after every two cycles of chemotherapy. ]
    Adverse Events (AEs) are reported by the NCI Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0. For each patient, worst grade of each event type is reported. Grade 3 = Severe, Grade 4 = Life-threatening, Grade 5 = Fatal.

  • Objective Response (Confirmed and Unconfined, Complete and Partial) [ Time Frame: at week 16, then every 3 months until progression ]
    Complete response (CR) is complete disappearance of all measurable and non-measurable disease. No new lesions. No disease related symptoms. Normalization of markers and other abnormal lab values. Partial response (PR) applies only to patients with at least one measurable lesion. Greater than or equal to 30% decrease under baseline of the sum of longest diameters of all target measurable lesions. No unequivocal progression of non-measurable disease. No new lesions. Confirmation of CR or PR means a repeat scan at least 4 weeks apart documented before progression or symptomatic deterioration.

  • Progression Free Survival [ Time Frame: 0 - 5 years ]
    Measured from date of registration to date of first observation of progression or symptomatic deterioration. Patients last known to be alive and progression-free are censored at date of last contact.

Enrollment: 22
Study Start Date: May 2005
Study Completion Date: May 2012
Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment
Cetuximab+Cisplatin+Irinotecan followed by radiation therapy (RT) in Cycle 3.
Biological: cetuximab
400mg/m^2 loading dose, intravenous (IV) over 120 min, day 1 of cycle 1 only. 250mg/m^2 maintenance dose, IV over 60 min, Days 8 & 15 of Cycle 1 and Days 1, 8, and 15 of subsequent cycles.
Other Name: Erbitux
Drug: cisplatin
30mg/m^2, bolus intravenous (IV), on Days 1 & 8 of each cycle.
Other Name: Platinol
Drug: irinotecan hydrochloride
65mg/m^2, intravenous (IV) over 30 min, on Days 1 & 8 of each cycle.
Other Name: CPT-11
Radiation: radiation therapy
The total dose to the prescription point will be 5,040 cGy given in 28 fractions. The patient will be treated with one fraction per day with all fields treated per day. 180 cGy will be delivered to the isocenter. The dose variation in the planning target volume (PTV) will be +7% and -5% of the prescription point dose.
Other Names:
  • RT
  • TRT

Detailed Description:



  • Determine the 2-year overall survival of patients with previously untreated, clinically unresectable, locally advanced squamous cell carcinoma or adenocarcinoma of the esophagus treated with cetuximab, cisplatin, irinotecan, and thoracic radiotherapy.


  • Determine the toxicity profile of this regimen in these patients.
  • Determine the probability of objective response (confirmed and unconfirmed, complete and partial) in patients with measurable disease treated with this regimen.
  • Determine the time to progression in patients with measurable disease treated with this regimen.
  • Correlate, preliminarily, gene expression (RNA) levels and germline polymorphisms of genes involved in DNA repair (e.g., ECRCC-1 and XRCC-1), drug metabolism (e.g., UGT1A1), and the epidermal growth factor receptor (EGFR) pathway (e.g., EGFR, interleukin-8, and vascular endothelial growth factor) with response, time to progression, overall survival, and toxicity in patients treated with this regimen. (This will not be completed as this study was closed due to poor accrual.)

OUTLINE: This is a multicenter study.

Patients receive cetuximab intravenous (IV) over 1-2 hours on days 1, 8, and 15. Patients also receive cisplatin IV and irinotecan IV over 30 minutes on days 1 and 8. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity. Beginning on day 1 of course 3, patients undergo thoracic radiotherapy once daily 5 days a week for 5-6 weeks (total of 28 treatments).

After completion of study treatment, patients are followed at 4 weeks and then every 3-6 months for up to 5 years after study entry.

PROJECTED ACCRUAL: A total of 75-100 patients (75 with adenocarcinoma and 25 with squamous cell carcinoma) will be accrued for this study.
