This situation is seen in patients of all ages, but older people are very vul­nerable.

Specificații That's a worldwide unbiased, personalized cancer research and advocacy service.

The nutritional deficit significantly increases the risk of postoperative complications and, consequently, the risk of death after surgery, being the main reason for hospital readmission.

This is due to the lack of sufficient biological resources to deal with the catabolism determined by the systemic inflammatory response.

Cancer, other chro­nic diseases and the surgical intervention trigger a systemic inflammatory reaction. This inflammatory res­ponse, whose intensity is determined by the extent of the sur­gi­cal act, leads to the intensification of glycogen and li­pid catabolism, with the release of glucose, free fatty acids and amino acids in the circulation.

The routine nutritional scre­ening in all oncology patients planned for surgery, fol­lowed by preoperative nutritional therapy, is essential for pre­ven­ting postoperative complications.

Aceas­tă situaţie se în­tâl­neş­te la toate vârstele, însă persoanele în vârstă sunt deo­se­bit de vulnerabile.

Deficitul nutriţional creş­te semnificativ ris­cul de complicaţii postoperatorii şi, implicit, ris­cul de de­ces după intervenţia chirurgicală, fiind principalul mo­tiv pen­tru gastric cancer nutrition guidelines pacienţii sunt reinternaţi în spital.

Acest lucru se da­to­rea­ză lipsei de resurse biologice suficiente pentru a face fa­ţă catabolismului declanşat de răspunsul inflamator sis­te­mic. Can­ce­rul, alte boli cronice şi intervenţia chirurgicală de­clan­şea­ză o reacţie inflamatorie gastric cancer nutrition guidelines.

Această reacţie in­fla­ma­to­­rie, a cărei intensitate este influenţată de amploarea actului chi­­rur­­gi­­cal, duce la intensificarea catabolismului glicogenului, a lipidelor şi, în lipsa rezervelor energetice, şi a proteinelor, cu eli­be­ra­rea în circulaţie de glucoză, acizi graşi liberi şi de ami­no­­acizi.

Efectuarea screeningului nutriţional de rutină la toţi pa­­cien­ţii cu cancer care urmează a fi supuşi unei intervenţii chi­rur­gi­cale, urmată de terapia nutriţională preoperatorie, este esen­ţia­lă pentru prevenirea complicaţiilor postoperatorii.

Cuvinte cheie cancer nutriţie oncologie geriatrică Introduction Surgery in patients with digestive neoplastic diseases is performed in a complex pathological context determined by: the oncological disease in different evolution stages; gastric cancer nutrition guidelines comorbidities; precarious gastric cancer nutrition guidelines status induced, on one hand, by the consumptive neoplasia and the metabolism deflected towards a hypercatabolic reaction, and, on the other hand, by the limitted alimentary intake due to inapetence, vomiting and digestive losses.

Among different localizations of digestive cancers, the gastric and esophageal neoplasm is associated with more severe alterations of the nutritional status.

The surgical stress determines significant endocrine, metabolic and immunological reactions. The effects of this process are the increase in energy consumption, increase of proteolysis, protein structural modifications, gastric cancer nutrition guidelines, and extravasation gastric cancer nutrition guidelines liquid from cells to the extracellular space 2.

Both surgery and anesthesia can alter the defense mechanisms and can depress the natural killer cells activity, essential for the destruction on neoplastic cells 3. Many local and general factors have been incriminated in the apparition of anastomotic fistulas. The local factors are related to the surgical act, in this category being included the hpv virus behandeln stage of the tumor 4the extended resections and the emergency surgery 5.

The general factors are represented by: male sexage, increased ASA risk 5diabetes mellitus 6other associated pathologies, and nutritional status at the admission. Nutritional status. The nutritional screening The nutritional status has been recognised as being important gastric cancer nutrition guidelines influencing the postoperative morbidity sincewhen Studley published data on the relationship between weight loss and mortality after gastroduodenal surgical interventions.

In recent years, this has been taken into consideration as an independent risk factor that can influence the apparition of gastric cancer nutrition guidelines fistulas 7,8. Therefore, it follows that the nutritional state at admission is a factor which significantly influences the postoperative outcome for every type of surgery, especially in patients with increased risk and other risk factors.

In these patients, a proper surgical technique in the absence of a preoperative preparation to correct the biological constants and gastric cancer nutrition guidelines nutritional status cannot reduce the incidence of fistulas The surgical act triggers an inflammatory reaction whose intensity is dependent on the extent of the surgical intervention.

The inflammatory process triggers a metabolic response consisting in the increase on the energy consumption.

Rolul nutriţiei în cancer - Gastric cancer journal impact factor The relationship between diet and cancer risk is complex. Citations per year Thermal food processing can result in carcinogenic byproducts. For instance, frying or smoking meat gastric cancer journal impact factor lead to the formation of polycyclic aromatic hydrocarbons such as benzopyrene. Smoked meat and smoked fish consumption has been linked to gastric cancer in countries with high intake, such as Japan.

The systemic inflammatory response generated by surgery is mediated by cytokines and has a major impact on metabolism, with the intensification of glycogen and lipid catabolism and, in the absence of energy reserves and proteins, with the release of glucose, free fatty acids and amino acids in the circulation. Apart from metabolic and endocrine reactions, the surgical stress determines important immunological reactions. ERAS Enhanced Recovery After Surgery recommendations 12initially created for improving recovery after colorectal oncological surgery, have been extended to other types of interventions.

The protocol includes among others: the limitation of preoperative abstinence for clear liquids at two hours, and at six hours for food, respectively; the administration of carbohydrates per os sweet liquids in the evening before surgery and two hours before the gastric cancer nutrition guidelines the avoidance of liquid overload both intraoperatively and postoperatively; the precocious gastric cancer nutrition guidelines the rapid introduction of the enteral alimentation in the first 24 hours ; the avoidance of opioids for pain relief, due to their effects of prolonged postoperative ileus.

These measures applied in the perioperative period are not enough gastric cancer nutrition guidelines preventing the postoperative complications in patients with preoperative weight loss.

In gastric surgery, ERAS protocol 13 reccomends to introduce oral or enteral nutritional gastric cancer nutrition guidelines beginning with the preoperative period. Table 1. In hospitalized patients there is carried out the final screening, which has two components: nutritional status and disease severity. Table 2.

For patients older than 70 years, one point is added to the final score.

This draws the attention to the relationship between preoperative malnutrition and the rate of complications and postoperative mortality. The nutritional deficit is often undiagnosed Another study Kuppinger,cited by ESPEN in 14revealed a good appreciation of the nutritional status using as assessing parameter only the appetite decline before hospitalization in patients who underwent abdominal surgery.

Other authors use modified nutritional screening scores The concept of preparation before surgery enters in another era, becoming an essential stage for preven­ting postoperative complications. It is important to underline that in patients without denutrition it is not indicated the protein calorie supplementation even after surgery, if gastric cancer nutrition guidelines restart of a sufficient per os administration is expected in less than seven days.

Finally, we must take into consideration that not all oncology patients with malnutrition can receive nutritional therapy.
