Panitumumab, Docetaxel, Cisplatin, Radiation Therapy, and Surgery in Treating Patients With Newly Diagnosed, Locally Advanced Esophageal Cancer or Cancer of the Gastroesophageal Junction

Phase 2
Completed
Conditions
Adenocarcinoma of the Gastroesophageal Junction
Esophageal Cancer
Interventions
Biological: panitumumab
Procedure: neoadjuvant therapy
Procedure: therapeutic conventional surgery
Radiation: radiation therapy
Registration Number
NCT00757172
Lead Sponsor
Alliance for Clinical Trials in Oncology
Brief Summary

RATIONALE: Monoclonal antibodies, such as panitumumab, 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. Drugs used in chemotherapy, such as cisplatin and docetaxel, work in different ways to kill tumor cells or stop them from growing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving combination chemotherapy together with panitumumab and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

PURPOSE: This phase II trial is studying how well giving panitumumab together with docetaxel, cisplatin, radiation therapy, and surgery works in treating patients with newly diagnosed, locally advanced esophageal cancer or cancer of the gastroesophageal junction.

Detailed Description

OBJECTIVES:

Primary

* To determine the pathologic complete response rate in patients with newly diagnosed, locally advanced adenocarcinoma of the distal esophagus or gastroesophageal junction treated with neoadjuvant panitumumab and combination chemoradiotherapy followed by surgery.

Secondary

* To determine the near-complete pathologic response rate in the primary tumor (≤ 10% residual viable cancer).

* To determine the overall survival and disease-free survival rates of these patients.

* To determine the safety profile of this regimen.

OUTLINE: Patients receive panitumumab IV over 1 hour, docetaxel IV over 1 hour, and cisplatin IV over 1-2 hours on day 1 in weeks 1, 3, 5, 7, and 9. Patients also undergo radiotherapy once daily 5 days a week beginning in week 5 and continuing for 5.5 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity. Beginning 6-9 weeks after completion of chemoradiotherapy, patients with no evidence of metastatic disease undergo esophagectomy.

After completion of study treatment, patients are followed every 3 months for 2 years and then every 6 months for 1 year OR every 6 months for 3 years.

Primary Outcome Measures
NameTimeMethod
Number of Participants With Pathologic Complete Response Following SurgeryPost surgery

Pathologic complete response (pCR) was defined as no viable residual tumor cells. A cellular residual mucin pools should be noted but also considered a pathologic complete response.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Near-complete Response Rate (≤ 10% Residual Cancer in Primary Tumor Viable)Post surgery
Percentage of Participants With 3-year Overall Survival3 years

Survival time was defined to be the length of time from start of study therapy to death due to any cause or until last follow-up (censored value).

Percentage of Participants With 2-year Disease-free Survival2 years

Disease-free survival was defined as the time from start of study therapy to documentation of disease recurrence. Participants who died without documentation of recurrence were considered to have had tumor recurrence at the time of death unless there was documented evidence that no recurrence occured before death. Participants who failed to return for evaluation after beginning therapy were censored for recurrence on the last day of therapy. Participants who experienced major treatment violations were censored for recurrence on the date the treatment violation occured.

Number of Participants With Frequent (>=15% Grade 3/4 Incidence) Adverse Events Regardless of AttributionWeek 1, 3, 5, 7, 9, 4-6 weeks after therapy and within 30 days post surgery

Adverse events were assessed by NCI CTCAE (Common Terminology Criteria for Adverse Events) v3.0. Grade 1= mild, grade 2= moderate, grade 3= severe, grade 4= life-threatening; and grade 5= death.
