Improvements to treatment strategies for patients with cancers of the upper gastrointestinal tract have produced a large population of people who remain free from cancer recurrence in the long term following treatment.

Surgery is the cornerstone of treatment for patients with these cancers, but while surgical removal of the tumour may offer the best chance of cure, these are major operations associated with specific long term complications. Weight loss and poor nutrition are common problems among patients who attain long-term cancer remission and cure after surgery. The mechanisms underlying these problems are not well understood and therefore treatment options are limited.

Our research has demonstrated increased levels of chemical messengers (gut hormones) released from the gastrointestinal tract after meals in patients who have previously undergone this type of surgery. These chemical messengers play a role in controlling appetite and interest in food, and increased levels after surgery may reduce interest in eating. Understanding the role of gut hormones in the control of appetite may allow us to use certain medications to block gut hormones and hence increase appetite, allowing patients to eat more and regain weight, preventing nutritional problems after surgery.

In this study, the investigators aim to determine whether exaggerated gut hormone secretion causes reduced appetite and interest in food after surgery. The information gained from this study may help us to develop treatments for patients with weight loss and nutritional problems after surgery.

Improvements to treatment strategies for patients upper gastrointestinal cancers have produced an increasing population of people who remain free from disease recurrence in the long term. Weight loss and nutritional problems are common among patients who attain long-term remission and cure after surgery for upper gastrointestinal cancers. However, the mechanisms underlying these problems are not well understood. In this study the investigators aim to determine whether reduced food intake after upper gastrointestinal surgery is caused by early satiety related to exaggerated post-prandial gut hormone responses.

This is a randomized, double-blind, placebo controlled, crossover study of the effect of 100μg octreotide SC on ad libitum food intake in patients free from complications or recurrence at least one year post-oesophagectomy, gastrectomy or pancreaticoduodenectomy. A comparator group of age, weight and gender matched subjects will be studied concurrently, and caloric intake and subjective symptom scores after administration of octreotide versus placebo among surgical and comparator subjects will be assessed.

Food Intake and Gut Hormones in Patients Who Have Undergone Upper Gastrointestinal Surgery for Cancer

Food Intake and Gut Hormone Release in Patients in Cancer Remission Who Have Undergone Upper Gastrointestinal Surgery

Serial assessment:

Fasting gut hormones, post-prandial gut hormone response to a standardized 400kcal meal

Used to assess post-prandial gut hormone response pre-operatively and at 10 days, 4 weeks, 6 months and 12 months post-operatively.

Standardized 400kcal semi-liquid meal

Surgery is the cornerstone of treatment for patients with oesophageal or gastric cancer, but while surgical removal of the tumour (oesophagectomy or gastrectomy) may offer the best chance of cure, these are major operations associated with specific long term complications. Weight loss and poor nutrition are relatively common problems among patients who attain long-term cancer remission and cure after surgery. The mechanisms underlying these problems are not well understood and therefore treatment options are limited.

The investigators research has demonstrated increased levels of chemical messengers (gut hormones) released from the gastrointestinal tract after meals in patients who have previously undergone upper gastrointestinal surgery. These chemical messengers play a role in signalling the feeling of fullness during and after a meal (satiety). Understanding the mechanisms involved in increased gut hormone secretion after these operations may allow us to use certain medications to block gut hormone release and hence reduce satiety allowing patients to eat more, regain weight and prevent nutritional complications after surgery.

Exaggerated post-prandial satiety gut hormone responses following oesophagectomy have, however, only been established cross-sectionally and therefore the time course for development of increased gut hormone secretion is unknown. Data collected from this study will provide important information about optimal timing of therapeutic intervention in this patient group, while offering mechanistic insights with regard to the pathophysiologic process underlying post-operative early satiety.
