Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Randomised study of patients that have not shown early response to standard chemotherapy. All participants receive the standard treatment of a 21 day cycle of Cisplatin 80mg/m2 (intravenously infused over 2 hours) Day 1 and 5-Fluorouracil 1000 mg/m2 (continuous infusion) Days 1-4. All participants are restaged at day 15 with Positron Emission Tomography (PET). If significant response then standard treatment is repeated over another 21 day cycle. However if no significant response, subjects will be randomised to receive either 2 x 21 day cycles of Cisplatin 60mg/m2 (intravenously infused over 2 hours) on day 22 & day 50, Docetaxel 35mg/m2 (intravenously infused over 1 hour) on Day 22, 29, 36, 50 ,57 & 64 & 5-Fluorouracil 150mg/m2 continuous intravenous infusion for 6 weeks starting Day 22 OR Cisplatin 60mg/m2 (intravenously infused over 2 hours) on day 22 & day 50, Docetaxel 35mg/m2 (intravenously infused over 1 hour) on Day 22, 29, 36, 50 ,57 & 64 & 5-Fluorouracil 150mg/m2 continuous intravenous infusion for 6 weeks starting Day 22 plus radiation 45Gy/25Fr starting Day 22. Radiation will be administered once daily, Monday to Friday on 25 occasions. All participants will have surgery in an attempt for complete resection, 4 - 8 weeks after completion of neoadjuvant therapy. The operation should aim to remove the tumour in total, with an adequate margin in each direction. This may be done as a subtotal esophagectomy with proximal gastric resection and a right intrathoracic oesophago-gastrostomy (Ivor–Lewis procedure), a subtotal oesophagectomy with proximal gastric resection and a cervical oesophago-gastrostomy (McKeon procedure). This is a complicated surgery often taking more than 6 hours.

Timepoint [1] 240484 0
Tumour samples will be taken at baseline and at surgery (after neoadjuvant therapy). After 23 patients have completed neoadujvant treatment and no histological responses have been observed then consideration will be given to stopping that particular arm.

Eligibility
Key inclusion criteria
1. Histologically proven invasive adenocarcinoma of the oesophagus or gastroesophageal junction.

2. Tumour thought to be T2 or greater or T1 tumours that are poorly differentiated or thought to be node-positive.

3. Technically resectable disease, as assessed in consultation with the intended surgeon.

4. Tumour is sufficiently F-18 fluorodeoxyglucose (FGD) avid on the initial staging PET scan to provide sufficient contrast between tumour and the surrounding normal tissues so that a response to the neoadjuvant therapy may be assessed.

5. Written informed consent of the patient according to local ethics committee guidelines.

Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Evidence of extrathoracic or extragastric spread apart from perigastric or mediastinal nodes, which are resectable. (Supraclavicular nodes renders the patient ineligible) 2. Tumour is located in the cervical oesophagus requiring pharyngolaryngectomy. 3. Tumour is predominantly within the stomach ie. most of the tumour is not involving the oesophagus or gastroesophageal junction. 4. Evidence of tracheo- or broncho oesophageal fistula. 5. Adequate haematological function. 6. Adequate renal function 7. Adequate liver function 8. Previous radiation therapy to the chest, previous chemotherapy within the last 5 years. 9. Previous malignancy for the previous 5 years apart from non metastatic Squamous Cell Carcinoma of the skin, Basal Cell Carcinoma or carcinoma in situ of the cervix. 10. Pregnant, lactating or inadequate contraception.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The study population will consist of patients with localised, resectable adenocarcinoma of the oesophagus or gastroesophageal junction. Patients that show less than a 35% reduction from the baseline PET scan standard uptake value (SUV) on a PET scan performed 15 days after the commencement of the first cycle of cisplatin/5-FU chemotherapy will be randomised between chemotherapy (cisplatin/5-FU with the addition of docetaxel) followed by surgery or chemotherapy (cisplatin/5-FU with the addition of docetaxel) and radiation followed by surgery. Patients are allocated treatment via telephone randomisation with the NHMRC clinical trials centre.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Treatment will be allocated using the minimization method, patients will be stratified using the following factors: Site of disease: OG Junction or Oesophogus and insitution.
