Delphine G, a 91-year-old woman, has a history of breast and stomach cancer, treated respectively with surgery, radiotherapy, hormone therapy, and surgery, chemotherapy. In early 2021, Mrs. G. underwent surgery for adenocarcinoma of the transverse colon. In the postoperative follow-up, the signs of disorientation present before the intervention increased. No adjuvant treatment was necessary, but faced with insufficient food intake, parenteral nutrition was undertaken. Cognitive functions worsened despite returning home, where Delphine fell several times. In March, the central venous catheter was torn off in a fall. Mrs. G. was more fatigued since stopping parenteral nutrition. Her daughter, the home nurse and the physiotherapist asked for a new catheter. But the insertion of the catheter was made impossible by major agitation. Due to the repeated requests of the daughter and the caregivers at the patient's home, a second attempt was made: it was a failure. Geriatric specialists and then the Ethics Committee were solicited. The geriatricians concluded that there was no indication of artificial nutrition, that any attempt to place a catheter under stress was deadlocked, and they suggested a “pleasure diet”. The Ethics Committee, taking up the cardinal principles of bioethics, concluded the same thing, but at the insistence of the patient's daughter and with the agreement of her oncologist, the patient was transferred to a nearby hospital for nasogastric tube placement. Her agitation made the installation difficult and the tube had to be repositioned several times. While enteral nutrition was started, the patient pulled on her tube, and following vomiting of digestive fluid and diet, inhaled massively and developed acute respiratory failure. Because of the therapeutic limitations collectively stated, it was decided not to intubate. Mrs. G. Delphine received oxygen at high flow, increasing sedation, and finally died 48 hours after the placement of the gastric tube. A few days later, Mrs. G.'s daughter filed a complaint with the hospital for “loss of chance”.
Why is Mrs. G.'s story illustrative? Because Delphine had advanced cancer, because she was old, because she was at the end of life. But also because the indication of the withdrawing of artificial nutrition has been at the origin of acute ethical dilemmas (about refusal of care, autonomy …), and subjective and emotional representations of both the family and the oncologist irrupted in the decision. Perhaps only pain is invested with such a symbolic weight that goes beyond the medical dimension. No other treatment, not even mechanical ventilation (though depository of the breath of life), would have crystallized so many medical, moral and social issues.
Through this story, we will successively examine the ethical implication of considering nutritional care as a human right for cancer patients, the social and cultural role of food, and the position of caregivers.
Nutrition: a physiological role, but above all a cultural and social one
In 2016, the ESPEN guideline on ethical aspects of artificial nutrition and hydration highlighted the importance of both nutritional and social aspects: “When independent ingestion of food and liquids is disturbed, nursing and medical procedures serve to cover the individual's vital need for nutrition as well as to fulfill these natural requirements with the purpose of enabling the individual to participate optimally in his/her social environment” [

]. Like philosophers, sociologists or anthropologists, doctors have pointed out the complex role of food in humans.
We cannot understand the ethical issues related to nutrition if we do not consider its symbolic function. According to Aristotle, nutrition is the main function of the general organization of the living and one of the main functions of the soul. In fact, according to this philosopher, the fourth part of the soul is the ‘nutritive soul’. But above all, the nutritional function is associated with reproduction: “The nutritive soul is the first faculty of the soul and the most common, the one by virtue of which life belongs to all. […] It includes both the assimilation of food and reproduction. The same faculty of the soul is both nutritious and generative.” The close link with life and fertility underlines this function of perpetuation of the person, but also of the species.
The act of feeding and eating and the surrounding environment therefore define man in his ecosystem, a full member of the species and an eminently social animal. This social function of food and meal is widely described: “Food is both an encounter of the subject with himself and a collective act” [
[6]Meeting the food, nourishing the encounter and representations : how to question the construction of ego through nourishment.
]. The French sociologist Pierre Bourdieu recalls that man makes the “meal a social ceremony, an affirmation of ethical dress and aesthetic refinement” [
[7]La distinction. Critique sociale du jugement.
]. In some cultures, eating is instituted as an art of living: being prevented from doing so, by disease or poverty, becomes thenceforth a double condemnation. For Delphine's family and her caregivers, the impossibility to receive artificially administered nutrition was perceived as a double signal of abandonment by the world of living beings.
Moreover, man as a social object is also defined in his environment by his feeding characteristics. Bourdieu recalls the role of “habitus” in our practices and even our tastes, “a choice of destiny, but a forced choice, produced by conditions of existence” [
[7]La distinction. Critique sociale du jugement.
]. When dependence on nutritional therapy occurs because of the disease, or when, conversely, the diet must finally be stopped, it is much more than a treatment that is introduced or stopped: it is a real social uprooting.
The expression of social differences through food remains attached to the sick until the end of their lives. Thus, according to their socio-professional categories, access to food exceptions or wine will or will not be tolerated by caregivers, in the name of both hygienic and moral preventions. However, “it is more what we have always loved, always had the habit of consuming, that is important to maintain as permanence, when the serious illness forces a ‘change of pace” [
[6]Meeting the food, nourishing the encounter and representations : how to question the construction of ego through nourishment.
]. Ethical issues are again at the forefront, between respect for autonomy and the desire not to harm. ESPEN's recommendations are not mistaken: “Other needs like the enjoyment of food and social aspects of feeding including humane attention are not satisfied by these routes of food supply, and should not be neglected as such” [

]. There is a dimension here, “food/drink pleasure”, which is usually only found in the category of comfort care; however, nutrition is a treatment, whose place is singular. This is probably why, when geriatricians and the Ethics Committee concluded that “only” a “pleasure diet” was mandatory for Delphine, the patient's daughter and the oncologist considered that the notion of pleasure was not compatible with the fighting spirit needed to survive. This last point is central because the distinction between treatment (i.e. cure) and care (comfort and pleasure according to patient's criteria) is in constant tension in clinical nutrition practice. This underlines the crucial need of early shared-decision making, advance care planning and end-of-life discussions, in order to avoid futile obstinacy when the end-of-life approaches.
If the place of nutrition is so remarkable in oncology, it is also because cancer and its treatments primarily attack the digestive organs and functions of nutrition. Anorexia, hypermetabolism and the consequent weight loss and sarcopenia testify to its severity; chemotherapy and radiotherapy are toxic to the entire digestive tract (mucositis, nausea, vomiting, functional disorders, etc.); disorders of taste and smell, food disgust, sometimes functional impairments of swallowing alter the quality of life and ability to eat under the effect of treatments or the course of the disease. Aristotle already noted this phenomenon five centuries before our era: “Healthy people judge healthy foods that are truly healthy, while the sick judge quite differently” [
].
In a situation of good health (while being aware of the relativity of “health”), food is therefore a vital need, a pleasure and a social act (in terms of productivity, food to work; and in the sense of a social bond). In a situation of disease, such as cancer here, all these functions remain true, but with distortions of these roles and of the perception of their necessity according to the stage of the disease. Nutrition becomes a full-fledged treatment: it is therefore part of the mandatory arsenal at the beginning of and during the course of illness. “Artificial nutrition and hydration are a medical intervention, requiring an indication, a therapeutic goal and the will (consent) of the competent patient [ …]” [

]. However, in an imminently dying situation, because of its treatment status, nutrition, and with it hydration, can be stopped, unlike other therapeutics or supportive care that are continued until the end of life (analgesics, anxiolytics, physiotherapy). Whether you are in the beginning or in the final phase of the disease, the principles of bioethics apply to nutrition as well as to other treatments [
[9]Principles of biomedical ethics.
]. These are the principles of beneficence, non-maleficence, autonomy, and justice.
A vital need, a fundamental right: the right to the benefit of nutritional care
“I will serve according to my power and my discernment a diet to the relief of the sick” (10). As art and science, Hippocratic medicine was based on two dietary imperatives: adapting healthy foods to human nature and adapting the diet to the condition of sick patients in order to avoid suffering and death. The imperative to provide for the nutritional needs of all, in an adapted and thoughtful way, therefore dates back to antiquity [
[4]La Nutrition en Médecine: approche épistémologique, problèmes éthiques et cas cliniques.
,
].
Recently, nutritional care access has been considered to be a human right linked to the right to food and the right to health. This implies that cancer patients should ideally have access to screening, diagnosis and assessment of malnutrition and the administration and monitoring of food and evidence-based medical nutrition therapy including artificial nutrition and hydration [

]. It is important to highlight that recognizing that nutritional care access is a human right does not imply there is an obligation to feed all patients at any stage of life and at any cost. From an ethical point of view, conversely, this right implies that the best decision for the cancer patient must be made and this may include, under certain circumstances, the decision to withdraw or withhold nutrition. Our patient, Delphine, was successively in both situations: as required, she benefited first from assessment and the onset of artificial nutrition, and several months later she was ordered to stop nutrition.
Applied together, human rights and health care ethics are closely linked as they support and complement each other [
[11]Human rights and ethics in public health.
]. According to E. Hirsch, human rights concepts “characterize and illuminate the issues of an ethical requirement in the fields of care and research.” [
[12]Droits de l’homme et respect de la personne. Traité de Bioéthique Tome I, Fondements, principes repères.
] Consequently, when it comes to feeding the sick cancer patient, respect for human rights and dignity are not abstract values, but take on a practical dimension “which defines a social order and places us under mutual obligations towards each other” [
[12]Droits de l’homme et respect de la personne. Traité de Bioéthique Tome I, Fondements, principes repères.
]. Recognizing the right to nutritional care as a human right establishes a commitment to a very important ethical responsibility that must be based on the respect of the four ethical principles (autonomy, beneficence, non-maleficence, and justice) as well as other principles such as vulnerability, equality and equity [
[3]Ethical issues and dilemmas in artificial nutrition and hydration.
,
[4]La Nutrition en Médecine: approche épistémologique, problèmes éthiques et cas cliniques.
]. Moreover, recognizing nutritional care as a human right implies the ethical duty of feeding the ill person in conditions of dignity.
Cancer occurs, and food often takes a back seat: the paradox of cancer nutrition
As a treatment, nutrition obeys the laws of right prescription and ethics. The first statement of international recommendations by Espen says: “Prerequisites of artificial nutrition and hydration are 1) an indication for medical treatment, 2) the definition of a therapeutic goal to be achieved and 3) the will of the patient and his or her informed consent.” [

] Nutrition is a part of the therapeutic arsenal in the same way as chemotherapy or surgery (and is not a vaguely humanitarian option, left to the care of volunteers or the family that brings food). Everything should contribute to place food at the heart of these concerns: its essential social and anthropological place, as seen above; its status of “basic need”, as defined by Virginia Henderson [
[13]The principles and practice of nursing.
]; the nutritional aggression of cancer and its treatments; its proven effectiveness, natural or artificial, to improve the prognosis [

].
However, we still often observe a paradoxical phenomenon when caring for a cancer patient: diet and nutrition take a back seat, sacrificed to the war against cancer and the will to heal. Because of its dual status (both physiological and socio-cultural), is it secondary and vaguely superfluous? Does being such an “object of pleasure” give food, taste, senses, a hint of guilt compared to the priorities of chemotherapy or surgery? This negligence is not the responsibility of doctors alone: oncologists, but also the patients themselves, obsessed with the imperative urgency of treating the cancer disease, focus all their efforts on heavy treatments, with etiological aims, relegating to second place a treatment that has become a simple support. Yet, what doctor would treat pneumonia with antibiotics alone while forgetting about oxygen? The fundamental right to be fed in a correct, adapted and thoughtful way [

], is therefore often abused. It is only much later, as life slips away and the clinical benefit of food wanes, that eating and drinking return to the forefront of human concerns; we will come back to this.
