Nutritional assessment of surgery patients

The advanced lung cancer inflammation index is a prognostic factor for gastrointestinal cancer patients undergoing surgery: a systematic review and meta-analysis

BACKGROUND

The advanced lung cancer inflammation index (ALI) is a comprehensive assessment indicator that can reflect inflammation and nutrition conditions. However, there are some controversies about whether ALI is an independent prognostic factor for gastrointestinal cancer patients undergoing surgical resection. Thus, we aimed to clarify its prognostic value and explore the potential mechanisms.

METHODS

Four databases including PubMed, Embase, the Cochrane Library, and CNKI were used for searching eligible studies from inception to June 28, 2022. All gastrointestinal cancers, including colorectal cancer (CRC), gastric cancer (GC), esophageal cancer (EC), liver cancer, cholangiocarcinoma, and pancreatic cancer were enrolled for analysis. We focused on prognosis most in the current meta-analysis. Survival indicators, including overall survival (OS), disease-free survival (DFS), and cancer-special survival (CSS) were compared between the high ALI group and the low ALI group. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist was submitted as a supplementary document.

RESULTS

We finally included fourteen studies involving 5091 patients in this meta-analysis. After pooling the hazard ratios (HRs) and 95% confidence intervals (CIs), ALI was found to be an independent prognostic factor for both OS (HR = 2.09, I² = 92%, 95% CI = 1.53 to 2.85, P < 0.01), DFS (HR = 1.48, I² = 83%, 95% CI = 1.18 to 1.87, P < 0.01), and CSS (HR = 1.28, I² = 1%, 95% CI = 1.02 to 1.60, P = 0.03) in gastrointestinal cancer. After subgroup analysis, we found that ALI was still closely related to OS for CRC (HR = 2.26, I² = 93%, 95% CI = 1.53 to 3.32, P < 0.01) and GC (HR = 1.51, I² = 40%, 95% CI = 1.13 to 2.04, P = 0.006) patients. As for DFS, ALI also has a predictive value on the prognosis of CRC (HR = 1.54, I² = 85%, 95% CI = 1.14 to 2.07, P = 0.005) and GC (HR = 1.37, I² = 0%, 95% CI = 1.09 to 1.73, P = 0.007) patients.

CONCLUSION

ALI affected gastrointestinal cancer patients in terms of OS, DFS, and CSS. Meanwhile, ALI was a prognostic factor both for CRC and GC patients after subgroup analysis. Patients with low ALI had poorer prognoses. We recommended that surgeons should perform aggressive interventions in patients with low ALI before the operation.

Preoperative nutritional evaluation, surgical site infection, and prognosis in patients with oral cancer

OBJECTIVES

The risk of postoperative infection after reconstructive oral cancer surgery is high and poses a problem in perioperative management. The objective of this study was to verify the association between preoperative nutritional indicators, surgical site infection (SSI), and long-term prognosis after reconstruction for oral cancer.

STUDY DESIGN

Sixty-seven patients admitted to a dental hospital were enrolled. The following nutritional indicators were examined: serum albumin level, modified Glasgow Prognostic Score, Miki's Glasgow Prognostic Score, prognostic nutritional index, platelet/lymphocyte ratio, neutrophil/lymphocyte ratio, lymphocyte/monocyte ratio, and the Controlling Nutritional Status tool. Statistical analyses were conducted to determine potential risk factors for SSI.

RESULTS

The Cox proportional hazards model demonstrated that SSI and platelet/lymphocyte ratio ≥211.4 were independent prognostic factors affecting survival. The results demonstrated that albumin <4.0 and platelet/lymphocyte ratio ≥211.4 were risk factors for SSI. Furthermore, albumin <4.0, platelet/lymphocyte ratio ≥211.4, and SSI were correlated with prognosis. Preoperative nutritional indicators were associated with SSI and prognosis in patients with oral cancer after reconstructive surgery.

CONCLUSION

Preoperative nutritional therapy is crucial for improving therapeutic outcomes in patients with oral cancer who require reconstructive surgery.

Sarcopenia is a strong predictive factor of clinical and oncological outcomes following curative colorectal cancer resection

BACKGROUND

Skeletal muscle depletion and subsequent functional loss is common in gastrointestinal malignancy. Usual markers of nutritional status may not be part of routine workup. The predictive value of sarcopenia was assessed and compared with clinically utilized factors. The aim of this was to assess the association between computed tomography assessed sarcopenia with outcomes in colorectal cancer resection.

METHODS

A total of 228 consecutive patients who underwent curative colorectal cancer resection were included. Skeletal muscle area was measured at L3, with pre-defined gender-specific cut-offs applied to a height standardized index. Albumin, body mass index and Subjective Global Assessment scores were recorded alongside measures of comorbidity. Predictors of complications, mortality, and recurrence were identified through multivariate logistic regression.

RESULTS

Computed tomography assessed sarcopenia was significantly associated with longer stays, complications, 30-day mortality, readmissions and recurrence at 1 year. Specific associations with major, respiratory and cardiac complications were seen. It independently predicted overall complications (odds ratio 2.96, confidence interval 1.19-7.35 P = 0.019), recurrence at 1 year (odds ratio 8.00, confidence interval 1.45-44.21, P = 0.017) and an increase in comprehensive complication index of 14 (P = 0.002). Subgroup analysis found sarcopenia predicted overall complications in rectal surgery and major complications in colonic surgery. American Society of Anesthesiologists predicted complications but not major complications while cancer stage also predicted recurrence rates.

CONCLUSIONS

Sarcopenia presents an objective, available predictive factor that may be superior to current biochemical and clinical measures of nutritional and functional status. This study found it to be predictive of complication rates and recurrence after curative in colorectal cancer resection.

The advanced lung cancer inflammation index predicts short and long-term outcomes in patients with colorectal cancer following surgical resection: a retrospective study

Background and Purpose

Several studies have proposed that the advanced lung cancer inflammation index (ALI), a new inflammation-related index, can be used for the prognosis assessment of various malignancies. However, few studies have reported its prognostic value in colorectal cancer (CRC). Therefore, this study explored the relationship between ALI and outcomes in CRC patients.

Methods

A total of 662 CRC patients who underwent surgery between 2012 and 2014 were included. The ALI was defined as: body mass index × serum albumin/neutrophil to lymphocyte ratio. The X-tile program identified the optimal cut-off value of ALI. Logistic regression analyses determined factors affecting postoperative complications. The Kaplan-Meier method and Cox proportional hazards analyses evaluated potential prognostic factors.

Results

The optimal cut-off of ALI in males and females were 31.6 and 24.4, respectively. Low-ALI was an independent risk factor for postoperative complications in CRC patients (odds ratio: 1.933, 95% CI [1.283-2.911], p = 0.002). Low-ALI groups also had significantly lower progression-free survival (PFS) and overall survival (OS), when compared with the high-ALI group, especially at advance tumor stages. Using multivariate analysis, ALI was determined as an independent prognostic factor for PFS (hazard ratio: 1.372, 95% CI [1.060-1.777], p = 0.016) and OS (hazard ratio: 1.453, 95% confidence interval: 1.113-1.898, p = 0.006).

Conclusion

ALI is an independent predictor of short and long-term outcomes in CRC patients, especially at advance tumor stages. The ALI-based nomograms can provide accurate and individualized prediction of postoperative complication risk and survival for CRC patients.

Computed Tomography-Determined Sarcopenia Is a Useful Imaging Biomarker for Predicting Postoperative Outcomes in Elderly Colorectal Cancer Patients

Purpose

This study aimed to establish whether computed tomography (CT)–determined sarcopenia is a useful imaging biomarker for postoperative outcome in elderly colorectal cancer (CRC) patients, and construct sarcopenia-based nomograms to predict individual outcomes after surgery.

Materials and Methods

CT imaging data of 298 elderly CRC patients who underwent surgery in 2012-2014 were retrospectively analyzed. Skeletal muscle mass was determined by CT, and sarcopenia was diagnosed based on the optimal cutoff value determined by X-tile program. The correlation between sarcopenia and risk of preoperative nutrition and postoperative complications was evaluated. A Cox proportional hazards model was used to determine survival predictors. Sarcopenia-based nomograms were developed based on multivariate analysis, and calibrated using concordance index and calibration curves.

Results

A total 132 patients (44.3%) had sarcopenia based on the optimum cutoff values (29.9 cm²/m² for women and 49.5 cm²/m² for men). Sarcopenia was an independent risk factor for preoperative nutrition (p < 0.001; odds ratio [OR], 3.405; 95% confidence interval [CI], 1.948 to 5.954) and postoperative complications (p=0.008; OR, 2.192; 95% CI, 1.231 to 3.903). Sarcopenia was an independent predictor for poor progression-free survival (p < 0.001; hazard ratio [HR], 2.175; 95% CI, 1.489 to 3.179) and overall survival (p < 0.001; HR, 2.524; 95% CI, 1.721 to 3.703). Based on multivariate analysis, we produced four nomograms that had better predictive performance.

Conclusion

CT-determined sarcopenia is a useful imaging biomarker for predicting preoperative nutritional risk, postoperative complications, and long-term outcomes in elderly CRC patients. The sarcopenia-based nomograms can provide a scientific basis for guiding therapeutic schedule and follow-up strategies.

Prognostic Significance of Low Body Mass Index and Betel-Quid Use in the 5-Year Survival Rates of Esophageal Squamous Cell Carcinoma Patients

AIM

This study aimed to examine the relationship between clinicopathological features, varied malnutrition criteria, and survival in esophageal squamous cell carcinoma (ESCC) patients.

METHODS

Six malnutrition criteria (body mass index (BMI) < 18.5 kg/m², serum albumin level < 3.5 g/dL, neutrophil-to-lymphocyte ratio (NLR) > 3.5, platelet-to-lymphocyte ratio (PLR) > 17, prognostic nutrition index (PNI) < 40, and blood total lymphocyte count (TLC) < 1,600 cells/mm³) were measured in 205 ESCC patients at the time of diagnosis. Malnutrition status and clinicopathological features were tested for prognostic effects on the 5-year survival rate.

RESULTS

Malnutrition rates vary according to nutrition assessment tools, ranging from 21.5% based on BMI < 18.5 kg/m² to 67.8% based on PNI < 40. These rates are associated with increased inflammation, but they showed no difference among various tumor stages. After adjustment of demographic variables and comorbid status, advanced tumor stage, low BMI at diagnosis, and betel quid use showed prognostic significance in the 5-year survival rate based on a multivariate logistic regression analysis.

CONCLUSIONS

Different nutrition assessment criteria produced different malnutrition rates. Advanced tumor stage, low BMI at diagnosis, and betel quid use were independent prognostic factors for worse survival of ESCC patients.

Predictive Value of Preoperative Sarcopenia in Patients with Gastric Cancer: a Meta-analysis and Systematic Review

PURPOSE

The impact of preoperative sarcopenia on postoperative complications and overall survival has been recently debated. Our meta-analysis aims to ascertain whether preoperative sarcopenia increases the risk of poor outcomes and to attempt to provide new ideas for the prognosis of outcomes for patients with gastric cancer.

METHODS

We searched for all relevant articles on PubMed, the EMBASE database, and Web of Science (up to September 1, 2017). Data synthesis and statistical analysis were carried out using RevMan 5.3 software.

RESULTS

Thirteen studies involving 4262 patients who underwent gastrectomy for gastric cancer were analyzed (sarcopenia group = 1234; non-sarcopenia group = 3028). The results showed that preoperative sarcopenia significantly associated with poor pathological staging (high pT: OR = 1.86, 95% CI = 1.49-2.31; P < 0.01; pN+: OR = 1.61, 95% CI = 1.33-1.94; P < 0.01; high TNM category: OR = 1.84, 95% CI = 1.53-2.22; P < 0.01). Patients with preoperative sarcopenia had an increased risk of total postoperative complications (OR = 2.17, 95% CI = 1.53-3.08; P < 0.01), severe complications (OR = 1.65, 95% CI = 1.09-2.50; P = 0.02), and poorer OS (HR = 1.70, 95% CI = 1.45-1.99; P < 0.01). The results of subgroup analyses revealed that patients with preoperative sarcopenia over 65 years old and those from Asian populations had higher risks for total postoperative complications and severe complications.

CONCLUSION

This meta-analysis reveals that preoperative sarcopenia may be used as a new indicator of poor pathological staging, impaired overall survival, and increased postoperative complications. Notably, patients with gastric cancer who are over 65 years old and from Asia should be routinely screened for sarcopenia before surgery to adequately assess the risk of postoperative complications in clinical practice.

Sarcopenia in gastric cancer: when the loss costs too much

Sarcopenia is a complex syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength. Malignancy is a major determinant of sarcopenia, and gastric cancer (GC) is among the most common causes of this phenomenon. As sarcopenia is a well-recognized poor prognostic feature in GC and has been associated with worse tolerance of surgical and medical treatments, members of the multidisciplinary team should be aware of the clinical relevance, pathogenic mechanisms, and potential treatments for this syndrome. The importance of sarcopenia is often underestimated in everyday practice and clinical trials, particularly among elderly or fragile patients. As treatment options are improving in all disease stages, deeper knowledge and greater attention to the metabolic balance in GC patients could further increase the benefit of novel therapeutic strategies and dramatically impact on quality of life. In this review, we describe the role of sarcopenia in different phases of GC progression. Our aim is to provide oncologists and surgeons dealing with GC patients with a useful tool for comprehensive assessment and timely management of this potentially life-threatening condition.

Sarcopenia: a new predictor of postoperative complications for elderly gastric cancer patients who underwent radical gastrectomy

BACKGROUND

A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy.

MATERIALS AND METHODS

We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia.

RESULTS

Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P < 0.001), compared with nonsarcopenic patients. The multivariate analysis demonstrated that sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P < 0.001) and the Charlson comorbidity index ≥2 (odds ratio: 3.357, 95% CI: 1.144-9.848, P = 0.027) were independent risk factors for postoperative complications.

CONCLUSIONS

Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

Reliability of nutritional assessment in patients with gastrointestinal tumors

ABSTRACT Patients with gastrointestinal cancer and malnutrition are less likely to tolerate major surgical procedures, radiotherapy or chemotherapy. In general, they display a higher incidence of complications such as infection, dehiscence and sepsis, which increases the length of stay and risk of death, and reduces quality of life. The aim of this review is to discuss the pros and cons of different points of view to assess nutritional risk in patients with gastrointestinal tract (GIT) tumors and their viability, considering the current understanding and screening approaches in the field. A better combination of anthropometric, laboratory and subjective evaluations is needed in patients with GIT cancer, since malnutrition in these patients is usually much more severe than in those patients with tumors at sites other than the GIT.

Sarcopenia is an Independent Predictor of Severe Postoperative Complications and Long-Term Survival After Radical Gastrectomy for Gastric Cancer: Analysis from a Large-Scale Cohort

Currently, the association between sarcopenia and long-term prognosis after gastric cancer surgery has not been investigated. Moreover, the association between sarcopenia and postoperative complications remains controversial. This large-scale retrospective study aims to ascertain the prevalence of sarcopenia and assess its impact on postoperative complications and long-term survival in patients undergoing radical gastrectomy for gastric cancer. From December 2008 to April 2013, the clinical data of all patients who underwent elective radical gastrectomy for gastric cancer were collected prospectively. Only patients with available preoperative abdominal CT scan within 30 days of surgery were considered for analysis. Skeletal muscle mass was determined by abdominal (computed tomography) CT scan, and sarcopenia was diagnosed by the cut-off values obtained by means of optimum stratification. Univariate and multivariate analyses evaluating risk factors of postoperative complications and long-term survival were performed. A total of 937 patients were included in this study, and 389 (41.5%) patients were sarcopenic based on the diagnostic cut-off values (34.9 cm²/m² for women and 40.8 cm²/m² for men). Sarcopenia was an independent risk factor for severe postoperative complications (OR = 3.010, P < 0.001), but not for total complications. However, sarcopenia did not show significant association with operative mortality. Moreover, sarcopenia was an independent predictor for poorer overall survival (HR = 1.653, P < 0.001) and disease-free survival (HR = 1.620, P < 0.001). Under the adjusted tumor-node-metastasis (TNM) stage, sarcopenia remained an independent risk factor for overall survival and disease-free survival in patients with TNM stage II and III, but not in patients with TNM stage I. Sarcopenia is an independent predictive factor of severe postoperative complications after radical gastrectomy for gastric cancer. Moreover, sarcopenia is independently associated with overall and disease-free survival in patients with TNM stage II and III, but not in patients with TNM stage I.
