About

In patients with esophageal cancer, treatment with curative intent can be given to medically fit patients without distant metastases. It may consist of chemoradiotherapy or surgery alone or in combination. Surgery in combination with chemotherapy is another option. For patients who are not medically fit for surgery or with unresectable invasion in adjacent structures the only alternative with curative intent is, with current knowledge, definitive chemoradiotherapy. In the current study the investigators aim to improve prognosis for patients not suitable for surgery. Patients receive treatment with conventional chemoradiotherapy (oxaliplatin, fluorouracil and radiotherapy) with the addition of a more recently developed drug, an antibody called cetuximab.

Full description

Patients are treated with three cycles of oxaliplatin and fluorouracil 750 mg/m2/24 hours, day 1-5. Each cycle lasts for 21 days. Oxaliplatin is given with 130 mg/m2 in the first cycle and in cycle 2 and 3 which are administered concomitant with radiotherapy the dose is reduced to 85 mg/m2.

A loading dose of cetuximab 400 mg/m2 is given one week before the start of radiotherapy, and thereafter 250 mg/m2 is given weekly during the course of radiotherapy.

Concomitant with chemotherapy radiotherapy to a total dose of 50 Gy is given (2 Gy once daily in 25 fractions, 5 days a week) with a photon beam linear accelerator.

After treatment patients are followed every 6 months for three years with clinical examination and a CT-scan.
