Anorexia iN Cancer Patients: ANCHOR

Recruiting

• Conditions: Gastric Cancer; Oesophageal Cancer

• Registration Number: NCT04791254
• Lead Sponsor: The Christie NHS Foundation Trust

Brief Summary

The rationale for this study is to prospectively investigate the outcomes of patients undergoing standard dietetic interventions alongside treatment for their advanced gastrointestinal cancers, and to further characterise the relationship with body composition.

A number of patients will be enrolled in a sub-study investigating the neuronal-enteroendocrine-hypothalamic axis.

Gut hormone study. Our hypothesis is that proinflammatory cytokines produced by the tumour can not only affect appetite directly through the vagal and the central melanocortin system but also indirectly though the enhanced EEC activity; either through increased number or increased function.

In this study, the investigators will explore and compare the pattern and levels (pre-prandial and post prandial) of the pro-inflammatory cytokines and gut hormones between stage-standardised anorexic and non-anorexic cancer patients and age-matched healthy controls.

Detailed Description

Poor nutritional status contributes significantly to poor outcomes in patients with upper GI cancers, in some patients, directly leading to death. Poor fitness, in terms of reduced muscle mass (sarcopenia) or physical performance, is associated with higher treatment toxicity and poor treatment outcomes.

However the relationship between different markers of nutritional status and body composition with fitness is not fully understood. It is also not known what impact dietetic interventions have on the reduced survival seen in patients with weight loss at baseline.

Finally, the underlying interaction between the neuronal-enteroendocrine-hypothalamic axis that regulates appetite is poorly understood but believed to be impaired in patients with upper GI cancers because of a number of altered mechanisms.

Therefore the rationale for this study is to prospectively investigate the outcomes of patients undergoing standard dietetic interventions alongside treatment for their advanced gastrointestinal cancers, and to further characterise the relationship with body composition.

In addition to the above patients in cohort C must meet the following criteria

Inclusion Criteria: Cohort C

2. Patients should be chemotherapy or immune therapy naïve.
3. Patients must be able and willing to fast for 8-10 hours. 4 5.1 Patients in the anorexic group must have completed the FAACT AC/S questionnaire and scored ≤24 in total score and ≤ 2 in the appetite specific question.

5.2 For inclusion in the non-anorexic group patients must have completed the FAACT AC/S questionnaire; the total score should be > 37 and ≥3 for the appetite specific question.

Inclusion criteria: Cohort D - healthy controls

3. Participants must be able to understand the study information given to them and be willing to give consent for trial participation.
4. Participants must have completed the FAACT AC/S questionnaire and scored ≤24 in total score and ≤ 2 in the appetite specific question, for the anorexic group. For inclusion in the non-anorexic group the total score should be > 37 and ≥3 for the appetite specific question.

Exclusion Criteria

• Participants are excluded from the study if any of the following criteria apply:

Exclusion criteria Cohort A:

1. Patients unable to give informed consent
2. Patients not undergoing systemic anti-cancer treatment at The Christie hospital, for example patients not deemed fit enough for treatment, patients having alternative treatments such as radiotherapy or surgery, or patients referred for 2nd opinions.

Exclusion criteria Cohort B:

1. Recent myocardial infarction or stroke
2. Recent abdominal, eye or thoracic surgery
3. A recent respiratory tract infection (within 3 weeks)
4. Any chest pain on the day of the test
5. A positive COVID-19 test

Exclusion Criteria Cohort C & D : all patients and healthy volunteers

1. Symptoms of dysphagia of any cause, oesophageal or gastric obstruction (assessed via medical history/O'Rourke score). Patients with O'Rourke score ≥2 will be excluded.
2. Presence of oesophageal stent or any other kind of feeding aid (nasogastric tube, nasoduodenal tube, gastrostomy, jejunostomy)
