Resection of the Esophagus and Subsequent Weight Loss
REWARD

Brief Summary
The investigators aim to ascertain how food reward signals and eating behaviour relates to the gut-brain pathway in weight-losing patients after curative surgery for oesophageal cancer, and how this pathway responds to clinical treatment for this unintentional weight loss. The primary outcomes are the blood oxygen level dependent (BOLD) signal on functional MRI (fMRI), and the breakpoint during the progressive ratio task (PRT - a measure of eating behaviour), how these differ in response to multiple clinical treatment options, as well as how they relate to weight gain while on treatment.

Outcome Measures
Primary Outcomes (2)
Change in BOLD signal
Measure of food reward on fMRI
Before and after 4 weeks of clinical treatment
Change in breakpoint at PRT
Measure of drive to eat
Before and after 4 weeks of clinical treatment
Secondary Outcomes (2)
Correlation of weight change during treatment with BOLD signal changes
Before and after 4 weeks of clinical treatment
Correlation of weight change during treatment with PRT breakpoint changes
Before and after 4 weeks of clinical treatment
Study Arms (2)
Sandostatin
This cohort will be the group who are undergoing routine clinical treatment with a long-acting somatostatin analogue to minimise abnormal gut hormone signalling, and thus reduce early satiety.
Mirtazapine
This cohort will be the group who are undergoing routine clinical treatment with a tetracyclic antidepressant to stimulate appetite.
Interventions
Patients undergo clinical treatment as indicated, they are studied before and after.
Eligibility Criteria
A cohort of post-esophagectomy patients at least 1 year after curative surgery, but struggling with unintentional weight loss of at least 10% baseline body weight, and thus candidates for clinical treatment.
You may qualify if:
- History of esophagectomy with gastric conduit reconstruction
- Recurrence-free at least 12 months post-operatively
- Weight loss ≥10% from premorbid weight, or requiring ongoing caloric supplementation
- Due to undergo clinical treatment for weight loss with Sandostatin or Mirtazapine
You may not qualify if:
- Pregnancy, breastfeeding
- Significant and persistent chemoradiotherapy and/or surgical complication
- Other active malignancy
- Exocrine pancreatic insufficiency detected using fecal elastase
- Uncontrolled diabetes mellitus
- Significant psychiatric disorder or cognitive decline or communication impairment limiting capacity to provide informed consent
- Severe dysphagia
- Other disease or medication which may impact gut hormone physiology
- History of significant food allergy, certain dietary restrictions
- Any definite contraindication to somatostatin analogue administration
- Claustrophobia, or any absolute contraindication to MRI scanning
- Metallic implants, precluding fMRI
