About

RATIONALE: Drugs used in chemotherapy, such as capecitabine, carboplatin, and paclitaxel, 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 chemotherapy together with radiation therapy may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of capecitabine when given together with carboplatin, paclitaxel, and radiation therapy in treating patients with esophageal cancer or gastroesophageal junction cancer.

Full description

OBJECTIVES:

Primary

• Determine the maximum tolerated dose and recommended phase II dose of capecitabine when administered with carboplatin, paclitaxel, and radiotherapy in patients with carcinoma of the esophagus or gastroesophageal junction.

Secondary

• Determine the radiographic and pathologic response rate in patients treated with this regimen.
• Correlate, preliminarily, tumor biomarker response with clinical response in patients treated with this regimen.

OUTLINE: This is an open-label, dose-escalation study of capecitabine.

Patients undergo radiotherapy once daily and receive oral capecitabine twice daily on days 1-5 and carboplatin IV over 30 minutes and paclitaxel IV over 1 hour on day 2. Treatment repeats weekly for 5 weeks in the absence of disease progression or unacceptable toxicity. Beginning at week 9 (4 weeks after completing chemoradiotherapy), some patients may undergo surgery to remove the tumor. Patients with unresectable or gross residual disease after completing radiotherapy may continue to receive capecitabine, carboplatin, and paclitaxel for as long as the chemotherapy is beneficial.

Cohorts of 3-6 patients receive escalating doses of capecitabine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

PROJECTED ACCRUAL: A total of 36 patients will be accrued for this study.
