Evaluation of the Administration of Artificial Nutrition by Feeding Jejunostomy During Neoadjuvant Treatment on Postoperative Morbidity in the Context of Esophageal or Stomach Cancer (FREJENO)

May 7, 2026 updated by: University Hospital, Bordeaux
Malnutrition is common at the time of diagnosis of esogastric cancers. However, there are no recommendations regarding preoperative nutritional support (type and duration) or on the impact of refeeding on postoperative morbidity and mortality.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Malnutrition is frequently associated with esogastric cancers at diagnosis (65-80% of cases). It has been shown that malnutrition in digestive oncology is linked to increased mortality, higher rates of postoperative complications, greater toxicity induced by chemoradiotherapy, and reduced survival. Furthermore, malnutrition present before the start of neoadjuvant treatment is likely to worsen during therapy, due to the occurrence of diarrhea, malabsorption, and dysgeusia during chemotherapy.

However, there are no recommendations regarding the use of nutritional support (type and duration) during the neoadjuvant treatment phase for esogastric cancers. Indeed, the data in the literature are quite heterogeneous regarding the duration of preoperative nutrition, ranging from a few days to several weeks, as well as the type of nutritional support to be used. No study has specifically investigated the evolution of nutritional status during this refeeding phase. As for postoperative complications, the results are mixed, although the trend suggests a reduction in postoperative complications for esophageal surgery. For gastric surgery, only one study examined surgical site infections and found a decrease in incidence when adequate nutrition was provided for more than 14 days before surgery. Nevertheless, postoperative mortality was not affected by improved nutritional status. Most of these studies are small retrospective series. The only prospective studies assessed preoperative nutrition for just 7 days before surgery, with limited sample sizes.

An educational review was published in 2012 highlighting the importance of nutritional support in malnourished patients, recommending nutritional supplementation for all patients: oral supplementation for non-malnourished patients, and jejunostomy feeding for malnourished patients.

In this context, the primary objective of this study is to evaluate the rate of postoperative complications with perioperative enteral nutrition compared to the absence of preoperative enteral nutrition.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Retrospective case-control study including patients with esophageal cancer treated with neoadjuvant therapy.

The control group consists of patients who did not receive enteral or parenteral nutrition during neoadjuvant treatment.

The case group consists of patients who received enteral or parenteral nutrition during neoadjuvant treatment.

Description

Inclusion Criteria:

  • Patient undergoing surgery for esophageal cancer
  • Malnourished patient at the time of management
  • Receiving neoadjuvant treatment

Exclusion Criteria:

  • Patient not malnourished at the time of management
  • Patient who did not receive neoadjuvant treatment
