Esophageal cancer is highly lethal. In Ontario in 2020, an estimated 900 patients were
diagnosed with esophageal cancer, while 860 died from it. In Canada, the figures are 2400
diagnoses and 2260 deaths. The incidence of esophageal cancer in Canada is projected to
increase over time, especially in males who are more likely to be obese and to suffer from
reflux disease.
Esophageal cancer is the malignancy associated with the highest risk for malnutrition. Before
their diagnosis, 80% of all patients with esophageal cancer have over 10-15% unintentional
weight loss. Strategies to palliate malnutrition in cancer patients and its consequences on
outcomes have been developed. In patient with severe nutritional risk, use of nutritional
support for at least 10-14 days has been recommended in a non-surgical, oncology population.
The European Society for Clinical Nutrition and Metabolism have recommended preoperatively
enteral nutrition for 5-7 days in cancer patients undergoing major abdominal surgery. In
addition, dietary counselling and oral nutritional supplement were suggested to prevent
weight loss and interruption of radiotherapy on patients undergoing radiation treatments for
head/neck or gastrointestinal malignancies. Routine enteral nutrition was not suggested
during chemotherapy-only treatments.
The type of supplements administered may have an impact on recovery. It was shown that
esophageal cancer patients receiving enriched glutamine, fibers and oligosaccharide
perioperative enteral supplementation had a shorter systemic inflammatory response syndrome
postoperatively and less surgical stress, which could in turn lead to reduced postoperative
immunosuppressive conditions. A recent retrospective study from Taiwan did show a slightly
improved 4-year overall survival rate and less mucositis on patients supported by enteral
feeding tubes with esophageal squamous cell carcinoma and undergoing neoadjuvant therapy.
However, there is still equipoise in the literature and most centers in Canada have moved
away from feeding tubes. At LHSC, feeding tubes were historically placed on every patient
during their induction treatment. Efforts are being made to spare patients from unnecessary
procedure, but patient selection is variable. Standardization of this practice is needed. A
recent retrospective study evaluating the effect of surgical enteral access prior to
induction treatment did not show nutritional or perioperative benefit. There was no
difference in postoperative complication rates and weight loss was similar. In fact,
dysphagia is felt to be significantly relieved after a single cycle of chemotherapy.
Percutaneous feeding tubes may not be required on all patients during induction therapy for
esophageal cancer.
Those feeding tubes are associated with high morbidity. Kidane et al have shown that 39.3% of
visits to the ED after an esophagectomy are due to feeding tubes problems (dislodgement,
blockage, infection). Of those ED visits for feeding tubes issues, 17% resulted to an
admission. Small bowel obstruction is also associated to percutaneous feeding tube placement
and selective use has been recommended. Perioperative use of feeding jejunostomy in
gastroesophageal cancer has been associate with a complication rate as high as 44%. Given the
related-morbidity, guidelines now recommend selective use of feeding tubes on high-risk
patients after esophagectomy. When patients undergoing chemotherapy present to the emergency
department with fever or infectious signs, data from the Ontario Cancer Registry show that
46% are admitted, increasing healthcare burden. At baseline, patients undergoing chemotherapy
are at high risk of presenting to the emergency department or having unplanned visit to the
cancer center, this figure going as high as 49% within 4 weeks of initiation of chemotherapy
in comparable jurisdictions. Efforts must be made to save an already strained system.
According to the 2020 Surgical Quality Indicator Report Summary from OH-CCO, our center has
the worst 30-day unplanned ED visit rate (45%, provincial mean 27%) after esophagectomy in
the province of Ontario. Anecdotally, it is felt that most of those cases are related to
feeding tubes complications. If these patients present to the ED due to feeding tubes
concerns after an esophagectomy, it is likely they would have presented during induction
treatment if they had a tube.
Alternative to feeding tubes exist (home IV hydration) which could become a less invasive and
more interesting solution.
The objective of this study is to assess the feasibility of a larger randomized controlled
trial evaluating unplanned visit to the ED or the outpatient clinic in patients eligible for
trimodality for esophageal cancer during their induction treatment, randomized into receiving
percutaneous enteral access for nutritional support versus not.
