Abstract

Liver transplantation, as an effective therapy for patients with liver cancer, plays an important role in improving the quality of life of patients. However, the complexity and trauma of liver transplantation can easily lead to the occurrence of malnutrition in patients, and then increase the risk of postoperative complications, which has aroused widespread clinical attention. Reasonable nutritional support can not only maintain the stability of the body’s internal environment, reduce the occurrence of complications, but also promote the recovery of liver and other organ functions. In recent years, with the in-depth understanding of nutritional metabolism after liver transplantation, the application of enteral nutrition and parenteral nutrition in nutritional support after liver transplantation has been increasingly extensive and achieved remarkable results. This paper discusses the effect of early postoperative nutritional intervention on patients with liver cancer and liver transplantation, and combined with its mechanism of action, can better understand the effectiveness of intervention, and provide reference for the development of scientific and reasonable nutritional support programs in clinical practice.

INTRODUCTION

As a highly malignant tumor of the digestive system, liver cancer has a hidden onset, rapid development and high degree of malignancy, which often leads to the diagnosis of patients in the middle and late stage. For these patients, liver transplantation, as an effective treatment, can significantly prolong the survival of patients and improve their quality of life. However, liver transplant patients often have a severely impaired liver function and are unable to compensate themselves before undergoing surgery[1]. At the same time, many uncertain factors such as the trauma of the operation itself and the anesthesia treatment during the operation will further aggravate the metabolic pressure of the body, resulting in insufficient nutrition of the patients. If timely intervention measures are not taken, patients will not only face significant weight loss, hypoproteinemia, but also lead to severe consequences such as cachexia, which to some extent seriously affect the recovery of patients’ liver function after surgery. Therefore, many domestic authoritative experts have reached a consensus and advocated the implementation of early and active nutritional support strategies for patients after liver transplantation[2].

With the rapid development of nutrition science, clinical medicine and surgical technology, the field of postoperative nutrition intervention has also made remarkable breakthroughs and progress. From the previous parenteral nutrition auxiliary means, the gradual transition to the popularization and application of enteral nutrition, and then to the customization of personalized nutrition plans, the nutrition intervention strategy has been further improved[3]. On the one hand, this series of development has built a more scientific nutritional security system for liver cancer patients with liver transplantation, and on the other hand, it also provides a new perspective and way to promote the postoperative recovery process and optimize the quality of life of patients. Based on this, this paper aims to review the nutritional status of patients with liver cancer and the influence of nutritional intervention on liver transplantation, focusing on the mechanism of nutritional intervention in improving the survival rate of patients with liver cancer and liver transplantation, reducing complications, and promoting organ function recovery, in order to provide theoretical basis and practical guidance for the postoperative management of liver cancer and liver transplantation.

ANALYSIS OF NUTRITIONAL STATUS AND POSTOPERATIVE EFFECTS OF LIVER CANCER
Nutritional status and influencing factors of patients with liver cancer

According to relevant studies, liver (Figure 1) is the main metabolic organ of the human body, and its lesions will inevitably increase the risk of malnutrition in patients[4]. Stachowska et al[5] reported in a meta-analysis that fiber supplementation was associated with favorable changes in body mass index (BMI), insulin homeostasis, and liver-related biomarkers in patients with nonalcoholic liver disease. Moreover, Lai et al[6] found that the severity of cirrhosis was related to the decreased activity of glutathione and its related enzymes. Among the global malignant tumors, liver cancer is the second deadliest, and the pathogenesis of this disease involves the individual health status of patients, environmental exposure and other aspects. Studies have revealed that the main reasons promoting the occurrence of liver cancer involve obesity and type 2 diabetes, etc., and after further investigation, it is found that nutrition status can become a key factor affecting the tumor process to a certain extent, especially in patients with advanced malignant tumors[7]. Therefore, the nutritional status of patients with malignant tumors has been paid more and more attention by clinicians. Zhang et al[8] found in their study that the risk of malnutrition was significantly higher in liver cancer patients receiving transarterial chemoembolization (TACE) treatment, and the risk of malnutrition was significantly positively correlated with their symptom groups. At the same time, studies have found that with the increasing age of patients, their liver function gradually declines, which, coupled with chronic diseases, may cause malnutrition to a certain extent[9]. In addition, in the study of Xi et al[10], it was further found that the progression of tumor-node-metastasis stages, the severity of anemia and the activity status of viral hepatitis B all affected the digestive and absorption functions of patients to varying degrees, thus further accelerating the occurrence of malnutrition in tumor patients.

Application value of nutritional intervention in patients with liver cancer after surgery

Studies have shown that stress conditions such as anesthesia and surgical trauma will trigger the body to enter a highly decomposed abnormal metabolic state, among which postoperative insulin resistance is particularly significant, which not only limits the effective use of glucose to a certain extent, but also may lead to a series of metabolic disorders. Thus, the malnutrition of patients is further aggravated and their liver function is seriously damaged[11]. The core of individualized nutrition nursing strategy is to accurately assess the nutritional risk of patients in advance, and comprehensively consider their current nutritional status, personal eating habits and energy needs and other factors, so as to develop targeted diet management programs for them. To some extent, this intervention can effectively improve the nutritional status of patients while at the same time, further promote the overall recovery process of patients[12].

Menozzi et al[13] conducted structured interviews with pancreatic cancer surgery patients by means of a 24-hour dietary recall aimed at evaluating the intake of all foods, beverages, and oral nutritional supplements consumed in the last 24 hours, in conjunction with muscle mass measurements to provide a comprehensive nutritional assessment for pancreatic surgery. This study points to the importance of a multidimensional, comprehensive preoperative nutritional assessment and appropriate perioperative nutritional interventions for patients undergoing major cancer surgery in improving tolerance and clinical outcomes of antitumor therapy. Personalized nutritional care played an active role in patients undergoing hepatectomy for hepatocellular carcinoma. It can not only significantly improve the nutritional status of patients to a certain extent, but also promote the metabolism and absorption efficiency of nutrients, thus further enhancing the immune function of patients and conducive to postoperative rehabilitation. At the same time, Sun et al[14] used patient subjective global assessment to develop a personalized nutritional intervention plan and selection of nutritional pathways after TACE for hepatocellular carcinoma. Patients were given oral nutritional solution for energy supplementation or intravenous nutrition for energy supplementation as needed with close monitoring of nutritional risk and electrolyte changes, and it was found that the incidence of gastrointestinal complications as well as electrolyte disorders were significantly reduced in the nutritional intervention group. The study concluded that for elderly patients with primary liver cancer, early enteral nutritional support was provided to them after TACE, and the results showed that this measure effectively improved the nutritional status of the patients, and also enhanced the liver function and immune function of the patients to a certain extent, which ultimately improved the prognosis of the patients. In addition, other studies have found that preoperative nutritional risk screening (NRS) and targeted nutritional supplementation based on the assessment results can, on the one hand, successfully solve the problem of nutritional imbalance[15]; on the other hand, postoperative complications can be significantly reduced, thus minimizing the length of hospitalization and enabling patients to recover more quickly. In addition, Yap et al[16] also confirmed through systematic analysis that perioperative nutritional intervention could effectively reduce postoperative infection, ascites, length of hospital stay, and increase body weight in patients undergoing hepatocellular cancer resection.

NUTRITION RELATED CLINICAL ASSESSMENT METHODS AND THEIR APPLICATION IN CANCER PATIENTS
Nutrition-related measurement indexes

Anthropometric indicators: When evaluating the physical condition of liver transplant candidates, BMI, upper arm circumference, hand grip strength and other indicators should be measured, and effective comprehensive evaluation should be carried out[17]. However, for most patients, these indicators may interfere with the measurement results due to the presence of peripheral edema and abdominal fluid. The accuracy of BMI in cancer patients may be reduced, so the accuracy of BMI can be improved to a certain extent by scientifically estimating and subtracting the amount of abdominal fluid and other body fluid accumulation to correct BMI value[18]. At the same time, other parameters such as upper arm circumference also serve as an effective basis for assessing the nutritional status of patients. In the aspect of assessing fat reserve and consumption, triceps skin fold thickness is mainly used to judge, and its change can indirectly reflect the metabolic status of the body to a certain extent[19]. In the study of Chong et al[20], it was found that skeletal muscle fluctuations occurred in liver transplant patients during the perioperative period. Meanwhile, 30% to 70% of liver transplant candidates were found to have decreased muscle mass and function. Studies have found that for liver transplant recipients, lower muscle mass will not only increase the incidence of complications, but also prolong the duration of intensive care unit stay and the need for mechanical ventilation, and may also lead to a decrease in survival[21]. Luo et al[22] introduced the concept of “BMI of abdominal effusion”, which dynamically adjusts the critical value of BMI mainly according to the severity of abdominal effusion. Compared with traditional BMI, it is more reliable in assessing patients’ malnutrition. In addition, in terms of upper body strength, hand grip strength has been recognized as an effective means of identifying patients with potentially high risk of complications and, to a certain extent, can be a unique predictor of assessing the likelihood of developing major complications in malnourished patients with cirrhosis over the next year.

Biochemical indexes: In the liver, a variety of key plasma proteins such as albumin, retinol-binding protein and enzymes involved in creatinine metabolism can be synthesized, and in this process, they are more susceptible to changes in liver health status and inflammatory response[23]. Therefore, serum albumin concentration and 24-hour urinary creatinine output are important indicators for evaluating nutritional status and predicting prognosis of liver transplant recipients to some extent. Albumin is a core indicator of protein reserve and liver function in the body, among which a low serum albumin level is widely regarded as a key factor to increase the risk of postoperative infection and reduce the survival rate[24]. Creatinine, as a byproduct of muscle metabolism, is produced at a relatively constant rate and is regulated by specific enzymes synthesized by the liver, thus further establishing a link with liver function. In addition, the decrease of 24-hour urinary creatinine excretion, which is an effective indicator for evaluating muscle mass, not only predicts a higher risk of death in patients to a certain extent, but also increases the possibility of transplant failure[25]. Therefore, by monitoring the serum albumin concentration and 24-hour urinary creatinine excretion during the perioperative period, the nutrition and health status of liver transplant recipients can be more comprehensively evaluated, which can further provide data support for the development of personalized nutrition intervention plans.

Biological resistance analysis: Bioelectrical impedance analysis (BIA) technology, as a convenient and safe detection method, is mainly used to measure the body’s reactance and resistance, so as to accurately reveal the body’s fat mass, somatic cell mass, phase angle and other key indicators[26]. As a core factor, phase angle is often recommended to be measured on the arm and thigh of patients[27]. Cereda et al[28] showed in related studies that BIA showed significant advantages in evaluating nutritional status and predicting survival in cancer patients. Moreover, Wang et al[29] believed that in the analysis of lung cancer patients, phase angle had higher predictive efficacy than albumin, transferrin and other indicators. At the same time, patients with low preoperative phase angle will not only suffer severe infection after surgery, but also significantly increase the risk of poor prognosis. In addition, phase angle also has the potential of preoperative volume assessment. On the one hand, accurate assessment can reduce blood loss to a certain extent during hepatectomy, and on the other hand, improve surgical safety[30]. Although BIA has a high accuracy in body composition analysis, pathological conditions such as edema and abdominal effusion may interfere with its measurement results, and the detection cost and professional equipment demand of this technology are high[31], so its clinical application is limited to a certain extent.

Nutritional assessment tools

NRS 2002: NRS 2002 is an evaluation system that comprehensively assesses a patient’s nutritional status by disease status, recent weight loss of 5% or more, reduction in food intake, BMI, and age[32]. Patients with an overall score of 3 or more are considered to be at significant risk of malnutrition and need to undergo a detailed nutrition screening procedure immediately. If the score is less than 3, it is recommended to maintain the frequency of re-evaluation once a week during hospitalization[33]. The NRS 2002 scoring system is mainly used as a preliminary screening tool for nutritional risk, but it is not enough to directly identify malnutrition and its specific degree in patients[34]. In the application, the accuracy and effectiveness of the evaluation system may be further reduced if the patient’s weight is not measured, or if the weight data is affected by fluid retention.

Malnutrition Universal Screening Tool: Based on the Malnutrition Universal Screening Tool (MUST) assessment system, key indicators such as a patient’s BMI, unwanted weight loss, and presence of acute disease, the risk of malnutrition was divided into three levels: Low, medium, and high[35]. Studies have shown that in the nutritional status assessment of patients with colorectal cancer, MUST shows a high degree of consistency with the patient’s subjective overall assessment[36]. However, the applicability of MUST in the medical field of liver transplantation remains to be further explored.

Royal Free Hospital-Nutritional Prioritizing Tool: The Royal Free Hospital-Nutritional Prioritizing Tool (RFH-NPT) is used to assess the nutritional health of patients with cirrhosis in terms of BMI, involuntary weight loss, and daily dietary intake. Patients were further subdivided into three risk levels: Low, medium, and high[37]. In view of the phenomenon of fluid retention in patients with cirrhosis, which significantly improves the complexity of screening for malnutrition to a certain extent, RFH-NPT includes the factor of fluid retention, and compared with NRS 2002, RFH-NPT has a higher sensitivity[38]. Therefore, in 2019 European Society for Parenteral Nutrition selected it as the preferred tool for nutritional screening of patients with liver disease.

Dietary Inflammatory Index: The Dietary Inflammatory Index (DII)[39] is a novel nutritional assessment index that evaluates the potential anti-inflammatory or pro-inflammatory effects of diets by categorizing dietary components into 36 anti-inflammatory and 9 pro-inflammatory components based on the ability of the food and nutrients to affect serum levels of inflammatory markers. Duggan et al[40] showed that diets with high DII scores were associated with an increased risk of breast and other cancers in women, and another cross-sectional study showed that[41] high DII scores were positively associated with levels of relevant non-invasive liver markers such as alanine aminotransferase, aspartate aminotransferase, and liver injury. Cross-sectional study noted that diets with high DII scores were positively associated with levels of non-invasive liver markers such as alanine aminotransferase, aspartate aminotransferase, and the development of liver injury. Although DII has been shown to be strongly associated with the development of several inflammation-related diseases, its value in patients with hepatocellular carcinoma is unclear and needs to be further explored.

CLINICAL APPLICATION OF EARLY NUTRITIONAL INTERVENTION IN PATIENTS WITH LIVER CANCER AND LIVER TRANSPLANTATION
Influence of malnutrition on liver transplant patients

Although the specific role of malnutrition on the prognostic mechanism of liver transplantation has not been fully revealed, studies have shown that malnutrition can significantly increase the risk of complications and death of patients, and is a key factor affecting postoperative survival[42]. In addition, the presence of malnutrition and sarcopenia is closely related to the increase of infection and mortality after liver transplantation[43]. Meanwhile, in the study of Prakash et al[44], it was found that for recipients of living donor liver transplantation, the occurrence of malnutrition would increase the duration of postoperative mechanical ventilation and intensive care unit stay. Lee et al[45] also confirmed this view in their study, in which they emphasized that although there are multiple factors that may affect the clinical outcome of liver transplant patients, low vitamin D3 content is an independent risk factor. In addition, the liver after transplantation is unable to obtain sufficient glycogen support and effective glucose uptake, so the nutritional intake of patients not only needs to meet the urgent needs of metabolism, but also needs to provide the necessary energy reserve for the transplanted liver. Insufficient nutritional support, on the one hand, will lead to the decline of immune function, slow wound healing and muscle and respiratory function decline in patients, on the other hand, will further aggravate the risk of postoperative complications and increase the mortality[46].

Preoperative early nutritional support for liver transplantation patients

Before liver transplantation, the prevention of sustained loss of nutrition and muscle reserve is the main core goal of nutritional support, and vitamin and mineral deficiencies should be further corrected to minimize the risk of infection and debilitation of patients[47]. Early effective intervention against malnutrition can not only significantly prolong the survival period of patients, improve the quality of life, but also reduce the occurrence of postoperative complications to a certain extent, thus creating favorable conditions for liver transplantation. Nutritional support mainly includes enteral nutrition and parenteral nutrition. According to European Society for Parenteral Nutrition guidelines, enteral nutrition is recommended as the preferred nutritional support means, which is not only more consistent with the natural physiological mechanism of the human body, but also can significantly reduce the risk of complications by maintaining the complete structure and barrier function of the gastrointestinal mucosa[48]. Victor et al[49] found through literature analysis that early nutritional supplementation before the operation of liver transplantation patients can reduce the hospital stay of patients to a certain extent, and has certain clinical safety. In addition, Ramachandran et al[50] found that probiotic supplements can improve the nutritional status of patients to a certain extent and play an important role in reducing the severity of liver disease after giving probiotic intervention to patients with cirrhosis who received liver transplantation. At the same time, Sadanand et al[51] found through research observation that taking Lactobacillus plant-based before transplantation could reduce the occurrence of postoperative infection. However, results of larger studies are still needed to determine the specific mechanism of nutritional intervention.

Early postoperative nutritional support for liver transplantation patients

For patients after liver transplantation, the core of nutritional management is adequate protein and energy supply, so as to avoid excessive protein catabolism caused by surgery to the greatest extent[52]. The high metabolic status often associated with malnutrition was significantly associated with lower survival rates. In recent years, clinical practice has confirmed that adequate nutritional intake in the early stage after liver transplantation is not only conducive to post-transplantation recovery, but also of great value in preventing post-transplantation complications[53]. Some specific nutrients that can play a complementary role in nutritional therapy after transplantation are called immune system modulators in clinic[54].

According to the study of Miyauchi et al[55], seven days before the ischemic injury of liver transplantation mice, after giving an enteral diet rich in antioxidant nutrients, adding vitamins C and E, and supplementing polyphenols, it was found that liver ischemia/reperfusion injury was significantly reduced, and antioxidant and inflammatory parameters could be improved to a certain extent, thus reducing liver cell injury. At the same time, Li et al[56] found in their study that in the early stage of liver transplantation, the recipient mice fed a supplemented tyrosine diet had longer survival time and reduced tissue damage. Moreover, in allograft liver transplantation, Pan et al[57] found that vitamin A could regulate gastrointestinal function after liver transplantation. In the study of Lindqvist et al[58], the nutritional regimen with a higher proportion of enteral nutrition and high-protein oral nutrition supplements in the early stage after liver transplantation would lead to increased protein intake of patients to a certain extent, but there was no significant difference between the two nutritional programs in postoperative severe outcomes. Although the current research on nutritional support for patients after liver transplantation due to biliary atresia, liver cancer, and non-alcoholic hepatitis is gradually in-depth, there is a relative lack of comprehensive nutritional management guidelines. Therefore, the indicators involved in this paper still need a large number of clinical studies to further improve.

THE MECHANISM OF EARLY NUTRITIONAL INTERVENTION IN LIVER TRANSPLANTATION FOR LIVER CANCER

In the human gut, there are complex microbial communities, including bacteria, fungi and archaea, which form a close mutually-beneficial symbiotic relationship with the human body. In a healthy state, the number and types of intestinal microbes remain constant, thereby jointly building the harmony of intestinal microecology. If this balance is broken, the imbalance of intestinal flora will be caused, which will not only lead to the disorder of intestinal function, but also affect the metabolism, cardiovascular, nervous and other systems of the human body, and then lead to a series of liver diseases[59].

Nutritional intervention and intestinal microecology

In recent years, studies have shown that nutrition intervention strategies have been proven to have significant effects on the regulation of human and animal intestinal microbial communities[60]. In this process, specific nutrients can not only act as an active participant in the energy supply or metabolic process, but also play a role in regulating the activity of the immune system, so it is considered as “immune nutrition”. With the in-depth discovery of clinical studies, glutamine, arginine and probiotics are all key substances in immune nutrition[61]. Moreover, studies have revealed that the three components of ecological immune nutrition, probiotics, prebiotics and biostime, can directly act on the intestinal microecosystem[62]. At the same time, the study of Hussain et al[63] confirmed that the increase of dietary nutrients such as protein and fiber was related to the diversity and composition of duodenal microbiome. Meanwhile, recent studies have shown that immune nutrition plays a key role in maintaining intestinal function and health, especially in the aspect of intestinal mucosal barrier[64]. Therefore, the intervention of immune nutrients shows a strong protective and supportive effect at these three levels.

On the other hand, hepatocellular carcinoma, as a systemic inflammatory disease, the inflammatory response triggered by pro-inflammatory factors is important in its pathogenesis. The level of short-chain fatty acids (SCFA), which are metabolites of the intestinal microbiota, is closely related to the level of inflammation in the body, and butyrate (SCFA) can inhibit pro-inflammatory cytokines through inhibition of mediating the activity of histone deacetylase and binding to the G protein-coupled receptor (GPR), GPR41 and GPR43, in order to reduce inflammation[65]. It can be seen that the regulation of intestinal flora SCFA-producing bacteria to become the dominant strain is important in the suppression of body inflammation. Related studies have shown that dietary polyphenol-rich foods such as pomegranate, grapes, and broccoli are able to enrich butyrate-producing bacteria in a targeted manner, while diets high in dietary fiber are able to enrich SCFA-producing bacteria in a targeted manner[66]. Under a reasonable dietary structure, it is recommended to moderately increase the intake of anti-inflammatory dietary components and reduce the intake of pro-inflammatory dietary components, which is important in maintaining intestinal microbial homeostasis as well as suppressing the body’s inflammatory response in tumor patients.

Mechanism of intestinal microecology in liver lesions and prognostic effects

In recent years, some scholars have observed significant changes in the structure and number of intestinal flora in patients with liver cancer, and this relationship between the gut and liver is called the “enterohepatic axis” (Figure 2). Yu and Schwabe[67] pointed out in their study that changes in intestinal flora are of great significance in determining the occurrence and development of hepatocellular carcinoma. Another study also confirmed significant changes in gut microbiota diversity in patients with liver cancer compared to healthy controls, and that porphyromonas and Bacteroides were associated with a reduced risk of liver cancer[68]. These findings reveal that the structural changes of intestinal flora in patients with early liver cancer can be used as a new marker for the diagnosis of early liver cancer to some extent, and its specific analysis is of great significance for the early warning of the disease.

Figure 2
Figure 2 Gut-liver axis. The occurrence of ischemia reperfusion injury in the liver can trigger immune and inflammatory responses, resulting in the aggregation of neutrophils, macrophages and other immune cells at the injury site and the release of a large number of pro-inflammatory factors, thereby affecting the functions of the intestine and liver. AMP-activated protein kinase pathway plays an important regulatory role in this process. IRI: Ischemia/reperfusion injury; IL: Interleukin; AMPK: AMP-activated protein kinase; SIRT1: Sirtuin 1; GSDMD: Gasdermin-D.

In the progression of liver cancer, the imbalance of intestinal flora interacts with it, and with the deterioration of the disease, the imbalance of intestinal flora will be further aggravated. In an animal experiment exploring the interaction between intestinal microbiota and liver cancer, it was found that intestinal microbiota depletion can impair intestinal tryptophan metabolism, thereby activating aromatics receptor, and thereby accelerate liver tumor genesis, and this process is related to up-regulation of sterol regulatory element-binding protein 2[69]. Feng et al[70] research team revealed that dysregulation of bile acid metabolism is related to the formation of cancer cachexia in mice. The experimental results showed that the intestinal flora of mice with hepatocellular carcinoma cachexia decreased in trichomillaceae and increased in enterobacteriaceae, and the microbial metabolism of bile acids decreased. Targeting bile acid metabolism with taurodeoxycholic acid and other drugs may contribute to the treatment of cancer cachexia. At the same time, studies have further confirmed that intestinal flora disturbance can lead to enterohepatic axis dysfunction by changing the bile acid metabolic pathway, thus promoting the occurrence and development of non-alcoholic fatty liver disease to a certain extent and accelerating its progression to cirrhosis and liver cancer[71].

In addition, the gut microbiota is an important modulator of the anti-tumor immune response in the liver. The body’s innate immune system activates the adaptive immune system by detecting the gut microbiota and its metabolites to exert anti-tumor effects. Previous studies have pointed out that Escherichia coli strain Nissle 1917 has enhanced anti-tumor immune effects and can significantly enhance the inhibitory effects of transforming growth factor receptor blockers on tumor growth and metastasis[72].

Liver transplantation and intestinal flora

For patients with end-stage liver disease, liver transplantation is the primary way to prolong their lives. Although the results are remarkable, complications such as postoperative infection and rejection may endanger the function of the transplanted liver to some extent and seriously affect the postoperative survival of patients. Liver transplantation not only affects the ecological balance of the recipient’s intestinal flora, but also causes significant changes in bacterial distribution and even causes abnormal bacterial migration[73]. At the same time, ischemia-reperfusion injury, immune rejection and antibiotic use during the operation together constitute the key factors for the imbalance of intestinal flora in the early stage after liver transplantation. Among them, ischemia-reperfusion injury is particularly critical, which not only weakens the integrity of intestinal mucosal barrier, promotes abnormal migration of intestinal bacteria, but also reduces intestinal immune function to a certain extent[74]. Bajaj et al[75] found that compared with homogenome, heterogenome showed a higher translocation rate of intestinal bacteria after transplantation, which was accompanied by a significant increase in endotoxin levels and aggravated liver function damage, further emphasizing the central role of immune mismatch in intestinal flora imbalance. Therefore, intestinal microbiography is also considered to be an important biomarker for predicting injury in liver transplantation[76]. At present, the prevention of intestinal flora imbalance and infection caused by bacterial displacement after liver transplantation has been widely studied. In a retrospective study, it was pointed out that the use of antibiotics before liver transplantation could destroy the microvilli of ileal epithelial cells, thus causing changes in the microflora, and thus effectively reducing liver transplant-related infections, thereby reducing liver injury and transplantation dysfunction[77]. At the same time, Jia et al[78] found that ciclosporin A could partially restore intestinal flora after liver transplantation and alleviate liver injury. However, further randomized controlled clinical trials are needed to elucidate the exact mechanism of action of these interventions, their target signaling pathways, and the optimal duration of treatment.

CONCLUSION
Status and challenges of early nutritional intervention in patients with liver cancer after liver transplantation

For liver transplantation patients with liver cancer, early postoperative nutritional intervention can effectively improve the prognosis of patients, and can reduce the incidence of postoperative infection and other complications to a certain extent. At the same time, changes in the patient’s gut flora play an important role in this process. However, despite the great potential of early nutritional intervention, it still faces multiple challenges in practical application. The first is the individual differences in nutritional needs. Patients have different nutritional status and metabolic needs before and after surgery. Therefore, targeted nutritional support plans need to be formulated. Secondly, postoperative complications and drug therapy may affect patients’ absorption and utilization of nutrients, and how to effectively maintain nutritional balance under these interfering factors is an important challenge. In addition, the collaboration of the healthcare team and the education of patients and families are also key factors in the successful implementation of nutrition interventions, and the lack of such support may affect the effectiveness of nutrition interventions.

Future research direction and development trend

Therefore, future research should aim to further explore strategies for individualized nutritional support and incorporate new nutritional drugs and treatments to optimize postoperative rehabilitation of liver transplant patients with liver cancer. In addition, interdisciplinary teamwork and the application of information technology may improve the efficiency and quality of nutritional support. With the advancement of science and technology and the increasing awareness of the importance of nutrition in disease management, it is expected that nutritional intervention will be more widely used and advanced in the field of liver transplantation for liver cancer in the future. The combination of these efforts will help to maximize the effect of postoperative nutritional interventions in liver transplant patients with liver cancer and improve the survival rate and quality of life of patients.
