The CRANE Trial

CRANE: Feasibility of a cluster randomised trial of a nutritional intervention to improve outcomes after cancer surgery in low-income countries.

Following GlobalSurg 3, our international cohort study examining surgical outcomes for cancer patients, CRANE will be the first high quality global trial of a nutritional supplement given to malnourished patients prior to cancer surgery in low & middle income countries.

It is estimated that two-thirds of patients undergoing cancer surgery in low- and middle-income countries (LMICs) are malnourished. Increasingly it is being recognised that boosting the health of patients before surgery can greatly improve the chances of a successful operation. The CRANE trial will be investigating the benefit of intensively treating patients in LMICs with nutritional supplements prior to surgery.

CRANE is a feasibility study funded by the UK Medical Research Council.

Aims & Objectives

  • Objective 1: to identify and validate a nutritional screening tool relevant to patients in LMICs

  • Objective 2: to identify a low cost sustainable nutritional intervention for cancer surgery patients in LMICs

  • Objective 3: to test the feasibility of  patient recruitment, retention & nutritionational supplement acceptability

Collaborating Countries

Crane is feasibility study being conducted in 5 partner countries

Trial Summary

For many types of cancer, high quality surgery is the only cure. This is particularly true in low-income countries where treatments such as chemotherapy or radiotherapy may not be available.

Malnutrition is a major public health issue in LMICs, with as many as two-thirds of hospitalised adults being malnourished. Cancer often causes extreme weight loss and, in many countries, this occurs on top of pre-existing malnutrition. Malnutrition is associated with higher post-operative mortality and morbidity, including longer length of inpatient stay and increased healthcare-associated costs.

It has been demonstrated that perioperative nutrition in patients undergoing gastrointestinal cancer surgery can halve postoperative complications, reduce post-operative stay and significantly impact on surgery-associated mortality. Nutritional supplementation provided at the time of surgery in LMICs could provide a low cost and sustainable intervention, requiring minimal specialist training and equipment to administer.

GlobalSurg 3 is providing data that will allow us to establish the relationship between malnutrition and surgical outcomes in a way that hasn’t been possible previously, but to find a solution to the problem we need a large scale trial testing nutritional interventions prior to surgery.
