Objective To summarize the nutritional assessment methods for liver cancer patients and their development, and to provide reference for rationally nutritional assessment and nutritional support. Method Domestic and foreign literatures were searched to summarize the nutritional assessment methods for liver cancer patients and their development, in order to determine a practical and feasible assessment method. Results The evaluation validity of traditionally nutritional assessment methods which contained many individual indicators was low. But subjective global assessment (SGA), mini nutritional assessment (MNA), and nutritional risk screening 2002 (NRS-2002) had similar evaluation validity, this 3 kinds of nutritional assessment methods were more suitable for liver cancer patients compared with the traditionally nutritional assessment methods. Conclusion The clinician should simultaneously apply SGA, MNA, NRS-2002, and other comprehensively nutritional assessment methods, as well as related anthropometric and laboratory indexes, to get a more accurate assessment of the nutritional status for patients with liver cancer.
Objective To explore the status of nutrition risk and its relative factors in patients of department of gastrointestinal surgery, and to observe the effectiveness of nutrition support on post-operative recovery of patients with gastric cancer. Methods A total of 1 048 cases of in-patients in Department of Gastrointestinal Surgery of Jinan Central Hospital Affiliated Shandong University from January 2015 to January 2016 were collected prospectively, and then screened the nutrition risk of these patients by nutritional risk screening 2002 (NRS-2002) and evaluated the actual malnutrition situation when they left hospital. Then collected 52 gastric cancer patients whose NRS-2002 score ≥3, and divided them to control group and experimental group randomly. The patients of experimental group received extra standard medical nutrition support while the patients of control group did not. Compared the nutritional indexes as well as some postoperative recovery indexes, such as the postoperative exhaust time, postoperative defecation time, infusion stop time, length of hospital stay, and incidence of complications. Results ① Nutritional risk. Among the 1 048 cases, 230 cases (21.9%) had nutritional risk while 118 cases (11.3%) developed to malnutrition. Age and degree of cancer were all related with nutritional risk (P<0.05) while gender was irrelevant (P>0.05). Patients with age ≥60 years, advanced gastric cancer, and colorectal cancer in Ⅲ+Ⅳ staging, had higher rates of nutritional risk than patients with age <60 years, early gastric cancer, and colorectal cancer inⅠ+Ⅱstaging. Results of actual malnutrition was in good accordance with the screening result of NRS-2002 (κ=0.57). ② Influence of nutritional support on gastric cancer patients. Compared with control group, there was an improvement in albumin, pre-albumin, and weight of experimental group and the distinction had statistical significance (P<0.05). The distinction of postoperative exhaust time and incidence of complication between the two groups were not statistically significant (P>0.05), but postoperative defecation time, infusion stop time, and the length of hospital stay of the experimental group were shorter than those of the control group with statistical significance (P<0.05). Conclusions The problem of malnutrition exists generally in the in-patients of department of gastrointestinal surgery. Applying the instrument of nutritional risk assessment to assess the risk as early as possible and giving appropriate nutrition support therapy positively, will make favorable influence to the prognosis of gastric cancer patients.
ObjectiveTo assess whether the geriatric nutritional risk index (GNRI) of elderly patients can be used as an evaluation index for complications after endovascular aneurysm repair (EVAR) of abdominal aortic aneurysm (AAA).MethodsA total of 265 patients with EVAR who received abdominal aortic aneurysm between January 2011 to December 2017 were included in this study from West China Hospital of Sichuan University. All patients included in this study were subrenal arterial AAA. Statistical analysis of clinical data was performed. The value of GNRI in evaluating postoperative complications of EVER patients was evaluated.ResultsOf the 372 patients, 158 were included in the GNRI abnormal group (GNRI≤98), and 214 were included in the normal group (GNRI>98). Univariate analysis showed that the age (P=0.04), drinking (P=0.04), serum albumin level (P<0.001), BMI (P<0.001), GNRI (P=0.004), and stroke (P<0.05) were risk factors that affects postoperative complications of AAA. Multivariate analysis showed that preoperative GNRI [HR=0.687, 95%CI: (0.487, 0.968), P=0.032] abnormality was one of the risk factors affecting postoperative complications of AAA.ConclusionFor patients undergoing endovascular aneurysm repair of abdominal aortic aneurysm, the GNRI is one of the important indicator for predicting postoperative complications.
ObjectiveTo analyze the perdictive value of Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP) for malnutrition or postoperative complications in children with critical congenital heart disease (CHD).MethodsA total of 875 children with critical CHD who were hospitalized in West China Hospital, Sichuan University form August 2019 to February 2021, including 442 males and 433 females with a median age of 30 (12, 48) months, were assessed by STAMP in Health Information System. Clinical data of postoperative complications were collected.Results(1) Based on World Health Organization Z-score as gold standard, 24.5% had malnutrition risk, and 34.3% were diagnosed with malnutrition. According to STAMP, the children were with medium malnutrition risk of 37.9% and high malnutrition risk of 62.1%. There was a statistical difference of incidence rate of malnutrition and detection rate of STAMP malnutrition risk in gender, age, ICU stay or length of mechanical ventilation (P<0.05); (2) with the optimal cut-off point of 5.5 in STAMP for malnutrition, the sensitivity, specificity, positive predictive value, negative predictive value and area under the curve (AUC) were 68.3%, 84.3%, 48.1%, 88.3% and 0.82, respectively; (3) 12.0% of the children were with postoperative complications; (4) with the optimal cut-off point of 5.5 in STAMP for postoperative complications, the sensitivity, specificity, positive predictive value, negative predictive value and AUC were 83.8%, 73.1%, 18.8%, 99.1% and 0.85, respectively.ConclusionChildren with critical CHD have a higher incidence of malnutrition risk and postoperative complications. STAMP has a good perdictive value for malnutrition or postoperative complications, however, the sensitivity and specificity of STAMP are affected by the gold standard or the cut-off point.
ObjectiveTo explore the value of geriatric nutritional risk index (GNRI) and sarcopenia on predicting postoperative complications in elderly patients with gastric cancer. MethodsAccording to the inclusion and exclusion criteria, the elderly (aged ≥60 years) patients with gastric cancer underwent radical gastrectomy in the Department of Gastrointestinal Surgery of Xuzhou Central Hospital from January 1, 2017 to December 31, 2021 were retrospectively gathered. The occurrence of postoperative complications (grade 2 or beyond by the Clavien-Dindo classification) was analyzed. The risk factors affecting postoperative complications were analyzed by univariate and multivariate logistic regression analyses to construct the prediction model, then was visualized by drawing a nomogram. The differentiation of the nomogram between the patients with postoperative complications and without postoperative complications was evaluated by the receiver operating characteristic (ROC) curve. The accuracy of the nomogram was evaluated by the calibration curve. Further, the clinical net benefit rate was analyzed by the decision curve analysis (DCA) to evaluate the clinical practicability. ResultsA total of 236 patients were gathered, 97 (41.1%) of whom had postoperative complications during hospitalization. The results of multivariate logistic regression analysis showed that the age, gender, GNRI, sarcopenia, surgical mode, and American Society of Aneshesiologists classification were the factors influencing the postoperative complications (P<0.05). The differentiation of nomogram based on the influencing factors was well, the area under the ROC curve was 0.732. The calibration curve showed that the model prediction curve was close to the ideal curve. The clinical net benefit rate by the DCA was higher when the probability of postoperative complications was 0.18 to 0.72. ConclusionsThe efficiency of nomogram based on GNRI and sarcopenia is well for predicting the occurrence of postoperative complications in elderly patients with gastric cancer. However, the nomogram needs to be further validated by prospective studies and external data.
ObjectiveBy mining data from the Database of Colorectal Cancer (DACCA) at West China Hospital of Sichuan University, this study aims to evaluate the relationship between nutritional risk screening (NRS) 2002 scores at initial diagnosis and long-term survival in patients. MethodsThe DACCA database version from November 24, 2023, was selected to compare the clinicopathological data of patients with NRS2002 scores <3 and ≥3, and to explore the impact of NRS2002 scores on survival. ResultsA total of 723 patients were screened, with 585 (80.9%) had NRS2002 scores <3 and 138 (19.1%) had NRS2002 scores ≥3. All 723 patients were followed up, with a follow-up period ranging from 1 to 78 months and a median follow-up time of 34 months. The median survival time for patients with NRS2002 scores <3 was 35 months, while it was 31 months for those with NRS scores ≥3. During the follow-up period, 589 patients (81.5%) survived, including 515 (71.2%) tumor-free survivors and 74 (10.2%) survivors with tumors. There were 134 deaths (18.5%), including 126 cancer-related deaths (17.4%) and 8 non-cancer-related deaths (1.1%). Multivariate logistic regression results showed that after controlling for 6 factors including age, radical surgery, adjuvant therapy, hypertension, differentation, and TNM staging, NRS2002 score was not a factor affecting the survival of colorectal cancer patients (RR=0.98, P=0.875). ConclusionNRS2002 score is not a predictive factor for the survival of colorectal cancer patients, possibly because although patients may have nutritional risks preoperatively, the long-term impact on survival is minimal following surgery and postoperative recovery.
ObjectiveTo understand the impact of preoperative nutritional status on the postoperative complications for patients with low/ultra-low rectal cancer undergoing extreme sphincter-preserving surgery following neoadjuvant therapy. MethodsThe patients with low/ultra-low rectal cancer who underwent extreme sphincter-preserving surgery following neoadjuvant therapy from January 2009 to December 2020 were retrospectively collected using the Database from Colorectal Cancer (DACCA), and then who were assigned into a nutritional risk group (the score was low than 3 by the Nutrition Risk Screening 2002) and non-nutritional risk group (the score was 3 or more by the Nutrition Risk Screening 2002). The postoperative complications and survival were analyzed for the patients with or without nutritional risk. The postoperative complications were defined as early-term (complications occurring within 30 d after surgery), middle-term (complications occurring during 30–180 d after surgery), and long-term (complications occurring at 180 d and more after surgery). The survival indicators included overall survival and disease-specific survival. ResultsA total of 680 patients who met the inclusion criteria for this study were retrieved from the DACCA database. Among them, there were 500 (73.5%) patients without nutritional risk and 180 (26.5%) patients with nutritional risk. The postoperative follow-up time was 0–152 months (with average 48.9 months). Five hundreds and forty-three survived, including 471 (86.7%) patients with free-tumors survival and 72 (13.3%) patients with tumors survival. There were 137 deaths, including 122 (89.1%) patients with cancer related deaths and 15 (10.9%) patients with non-cancer related deaths. There were 48 (7.1%) cases of early-term postoperative complications, 51 (7.5%) cases of middle-term complications, and 17 (2.5%) cases of long-term complications. There were no statistical differences in the incidence of overall complications between the patients with and without nutritional risk (χ2=3.749, P=0.053; χ2=2.205, P=0.138; χ2=310, P=0.578). The specific complications at different stages after surgery (excluding the anastomotic leakage complications in the patients with nutritional risk was higher in patients without nutritional risk, P=0.034) had no statistical differences between the two groups (P>0.05). The survival curves (overall survival and disease-specific survival) using the Kaplan-Meier method had no statistical differences between the patients with and without nutritional risk (χ2=3.316, P=0.069; χ2=3.712, P=0.054). ConclusionsFrom the analysis results of this study, for the rectal cancer patients who underwent extreme sphincter-preserving surgery following neoadjuvant therapy, the patients with preoperative nutritional risk are more prone to anastomotic leakage within 30 d after surgery. Although other postoperative complications and long-term survival outcomes have no statistical differences between patients with and without nutritional risk, preoperative nutritional management for them cannot be ignored.
