Usefulness of Preoperative Controlling Nutritional Status in Predicting Prolonged Hospitalization and Incidence of Postoperative Delirium for Elderly Hepatectomy with Hepatocellular Carcinoma

The number of elderly patients with hepatocellular carcinoma (HCC) has been increasing, but it remains unclear whether hepatectomy can be performed using the same criteria as in younger patients. Furthermore, the appropriate preoperative evaluation for hepatectomy in elderly patients is not yet clearly defined. Here, we investigated the applicability of preoperative assessment using the Controlling Nutritional Status (CONUT) score to help improve hepatectomy outcomes in elderly patients with HCC. This was a single-center retrospective analysis, and the study population comprised 64 consecutive patients who underwent hepatectomy for HCC between January 2012 and August 2016. We compared the preoperative assessment and perioperative outcomes between elderly (≥ 75 years old) and younger (< 75 years old) patients. A total of 61 patients were reviewed. Poor preoperative CONUT score was associated with a longer postoperative hospital stay in elderly patients undergoing hepatectomy for HCC. In addition, although elderly patients had similar perioperative outcomes to younger patients, the incidence of delirium was significantly higher, and univariate analysis confirmed that old age is a risk factor for delirium among the preoperative factors. Hepatectomy for HCC in the elderly can be safely performed with appropriate preoperative nutritional assessment using CONUT score and prevention of postoperative delirium. Preoperative nutritional assessment using the CONUT score was useful in predicting prolonged hospitalization for elderly hepatectomy with HCC.

Relationship between the Controlling Nutritional Status Score and Infrainguinal Bypass Surgery Outcomes in Patients with Chronic Limb-threatening Ischemia.

Objective: We investigated the association between Controlling Nutritional Status (CONUT) scores and the outcomes of bypass surgery in patients with chronic limb-threatening ischemia (CLTI).Methods: We retrospectively calculated preoperative CONUT scores in 118 patients (127 limbs) with CLTI who underwent infrainguinal bypass surgery. Survival, graft patency, and limb salvage were compared between the high and low CONUT score groups based on the respective cutoff points.Results: The median and mean CONUT scores were 5 and 4.8, respectively. The postoperative survival rate was lower in the high CONUT score (3–12) group than in the low CONUT score (0–2) group (P=0.0043). The limb salvage rate after arterial reconstruction was also significantly lower in the high CONUT score (8–12) group than in the low CONUT score (0–7) group (P=0.0009).Conclusions: The CONUT score can predict infrainguinal bypass surgery outcomes in patients with CLTI.

The prognostic significance of controlling nutritional status (CONUT) score for surgically treated renal cell cancer and upper urinary tract urothelial cancer: a systematic review and meta-analysis.

In order to evaluate the predictive effect of the controlled nutritional status (CONUT) score on the prognosis of patients with renal cell carcinoma (RCC) and upper urinary tract urothelial carcinoma (UTUC), a meta-analysis was performed. This systematic review has been registered on PROSPERO, the registration ID is CRD42021251879. A systematic search of the published literature using PubMed, Web of Science, Cochrane Library, EMBASE, and MEDLINE was performed. The fields of "renal cell cancer," "upper tract urothelial cancer," and "controlling nutritional status" and other fields were used as search terms. STATA 16 software was used to carry out data merging and statistical analysis of binary variables, Q test and χ2 tests were used to verify the heterogeneity between the included works of studies. Subgroup analysis and sensitivity analysis were used to explain the sources of heterogeneity between studies. Begg's test was used to assess publication bias between studies. From the first 542 studies retrieved, through strict inclusion and exclusion criteria, 7 studies finally met the requirements and were included in the meta-analysis. Pooled results indicated that high CONUT indicates worse over survival (OS) [HR = 1.70, 95% CI (1.43-2.03), P = 0.02], cancer-specific survival (CSS) [HR = 1.84, 95% CI (1.52-2.23), P = 0.01], recurrence-free survival (RFS) [HR = 1.60, 95% CI (1.26-2.03), P = 0.116], and disease-free survival (DFS) [HR = 1.47, 95% CI (1.20-1.81), P = 0.03]. Based on cancer type, cutoff value, region, and sample size, a subgroup analysis was performed. The results showed that OS and CSS were not affected by the above factors, and the high CONUT score before surgery predicted worse OS and CSS. In conclusion, this meta-analysis revealed that the preoperative CONUT score is a potential independent predictor of the postoperative prognosis of RCC/UTUC patients. A high CONUT predicts worse OS/CSS/DFS and RFS in patients.

Controlling nutritional status (CONUT) score-based nomogram to predict overall survival of patients with pancreatic cancer undergoing radical surgery

/Objective: As a new immune-nutritional marker, the controlled nutritional status (CONUT) score has been reported to predict the prognosis of cancer patients. We aimed to elucidate the prognostic value of preoperative CONUT score in pancreatic cancer patients undergoing radical surgery, and to construct a nomogram based on CONUT score to predict individual survival. Preoperative CONUT scores were calculated prospectively in 382 patients with pancreatic cancer who underwent radical surgery. Evaluated the relationship between CONUT score and pancreatic cancer prognosis. Cox proportional hazard models were used to determine predictors of survival and a new nomogram was established to predict pancreatic cancer overall survival (OS). The area under curve of CONUT score was higher than other immune-nutritional indexes. The OS of the high-CONUT group were significantly lower than that of low-CONUT group. Multivariate analysis showed that CONUT score, gender, AJCC stage, complications and reoperation were independent prognostic factors for OS. Nomogram based on these variables has better discriminant ability in predicting survival compared with other traditional staging systems. Preoperative CONUT score is an effective independent predictor of OS in pancreatic cancer patients undergoing radical surgery. This new CONUT based nomogram provides accurate, individualized survival prediction for pancreatic cancer.

The prognostic value of the Controlling Nutritional Status score on patients undergoing nephrectomy for upper tract urothelial carcinoma or renal cell carcinoma: a systematic review and meta-analysis.

In recent years, the controlling nutritional status (CONUT) score has increasingly became an effective indicator associated with tumor prognosis. This study was conducted to synthesise data on the prognostic value of CONUT score on patients with upper tract urothelial carcinoma (UTUC) or renal cell carcinoma (RCC) undergoing nephrectomy. We designed and performed a systematic analysis of studies that verified the correlation between preoperative CONUT score and prognosis for UTUC and RCC using PubMed, Web of Science and Embase. The conclusion was clarified by pooled hazard ratios (HR) and 95% confidence intervals (95% CI). Subgroup analysis were further conducted in accordance with different primary tumor. Six studies involving 3529 patients were included in this evidence synthesis, which revealed that the CONUT score had a potential role to predict the survival of UTUC and RCC patients accepting surgery. Pooled analysis showed that the overall survival (OS, HR 2·32, p < 0·0001), cancer-specific survival (CSS, HR 2·68, p < 0·0001) and disease-free survival (DFS, HR 1·62, p < 0·00001) were inferior in the high CONUT score group when compared with low score group. Subgroup analysis revealed that this result was in line with UTUC (OS: HR 1·86, p = 0·02; CSS: HR 2·24, p = 0·01; DFS: HR 1·54, p < 0·00001) and RCC (OS: HR 3·05, p < 0·00001; CSS: HR 3·47, p < 0·00001; DFS: HR 2·21, p = 0·0005) patients respectively. Consequently, the CONUT score is a valuable preoperative index to predict the survival of patients with UTUC or RCC undergoing nephrectomy.

Development of a New Recurrence-Free Survival Prediction Nomogram for Patients with Primary Non-Muscle-Invasive Bladder Cancer Based on Preoperative Controlling Nutritional Status Score.

BackgroundBladder cancer is the second most prevalent neoplasm in the urogenital system in terms of morbidity and mortality, and there is an urgent need for a more accurate assessment of individual prognosis in patients with primary non-muscle-invasive bladder cancer (NMIBC). The Controlling Nutritional Status (CONUT) score is an emerging biomarker score which has been confirmed to have prognostic value in various malignant tumors. The study attempted to systematically identify the prognostic role of preoperative CONUT score on posttreatment recurrence-free survival (RFS) in patients with NMIBC, and determine the predictive value and feasibility of the new prognostic prediction model.MethodsA total of 94 patients with NMIBC were analyzed retrospectively between January 2011 and December 2015. Statistical analysis was conducted using the nonparametric method. The Kaplan-–Meier method was used to assess recurrence-free survival (RFS), and Log rank tests was used to analyze the equivalences of survival curves. We used univariate and multivariate Cox proportional hazards regression model to identify important predictors of RFS. Discrimination of nomogram was measured by the concordance index. Predictive accuracy of the model was evaluated using the internal validation.ResultsIn univariate analysis, age, history of smoking, pathological T stage, tumor grade, tumor size, and CONUT score were significantly correlated with RFS. Multivariate analysis indicated that CONUT score (HR =3.855, 95% CI 1.242–11.970, p=0.020) was an independent predictor of RFS in patients with NMIBC. Based on significant parameters in multivariate analysis and reliable recurrence predictors determined in predictive models and relevant guidelines, a new age-, history of smoking-, pathologic factors- and the CONUT score-based scoring model was developed to predict recurrence of NMBIC. In addition, we internally validated the nomogram using the consistency index and calibration plots, which demonstrated that the model has high prediction accuracy (c-index= 0.851).ConclusionThe development of a new nomogram based on CONUT score could increase the accuracy of recurrence prediction and improve individualized treatment plans for patients with NMIBC.

Prognostic impact of the pre-treatment controlling nutritional status score in patients with non-small cell lung cancer: A meta-analysis.

Background:The influence of pre-treatment controlling nutritional status (CONUT) score on the prognosis of non-small cell lung cancer (NSCLC) patients is inconclusive. We performed this meta-analysis to evaluate the prognostic significance of CONUT score in NSCLC patients.Methods:A systematic literature review was conducted using PubMed, Embase, and the Cochrane Library databases. The hazard ratio (HR) and 95% confidence interval (CI) were extracted to assess the correlation between the CONUT score and the overall survival (OS), disease-free survival (DFS), recurrence-free survival (RFS), as well as the cancer-specific survival.Results:A total of 11 studies with 3029 patients were included in the analysis. Pooled results indicated that a high CONUT score was positively correlated with poor OS (HR: 1.63, 95%CI: 1.40–1.88, P < .001) and shortened DFS/RFS (HR: 1.65, 95%CI: 1.35–2.01, P < .001), but no significant relationship with the cancer-specific survival (HR: 1.28, 95%CI: 0.60–2.73, P = .517) was identified. The negative effect of high CONUT score on the OS and DFS/RFS was detected in every subgroup with varying treatment methods, cancer stage, CONUT cut-off values, sample size, and analysis methods of HR. Additionally, preoperative high CONUT score was an independent predictor of postoperative complications (odds ratio: 1.58, 95%CI: 1.21–2.06, P = .001) in NSCLC. Last but not least, high CONUT score was not significantly correlated with the patients’ sex, smoking status, cancer stage, lymphatic invasion, vascular invasion, pleural invasion, and pathological cancer type.Conclusion:These results demonstrate that high CONUT score is positively related to poor prognoses. The CONUT score may therefore be considered as an effective prognostic marker in NSCLC patients.

Preoperative controlling nutritional status (CONUT) score is a prognostic factor for early-stage cervical cancer patients with high-risk factors

ObjectiveThe goal of the study was to confirm whether preoperative controlling nutritional status (CONUT) was a prognostic factor in early-stage cervical cancer patients with high-risk factors after surgery and postoperative concurrent chemoradiotherapy (CCRT). MethodsBetween 2004 and 2015, a total of 698 patients who were treated with surgery and postoperative CCRT were included in this retrospective study. The prescribed dose for postoperative radiotherapy was 45–50.4 Gy in 25–28 fractions and the concurrent chemotherapy regimen contained cisplatin or paclitaxel. Based on the receiver operating characteristic (ROC) analysis, the patients were classified into low (<3) and high (≥3) CONUT groups. ResultsOf all study patients, 471 (67.5%) patients were included in the low CONUT group. The low CONUT group had significantly better 5-year disease-free survival (DFS) and overall survival (OS) than the high CONUT group (p<0.001 and p = 0.001, respectively). A high CONUT score was significantly associated with lymph node metastasis, parametrial invasion, and poorer nutritional status, including lower body mass index (BMI) and lower prognostic nutritional index (PNI) score (p<0.05, respectively). The CONUT score was an independent predictor of DFS and OS in multivariate analysis. Notably, the CONUT score still efficiently stratified DFS in the high PNI score group (P = 0.001). ConclusionsThe preoperative high CONUT scores indicated poor prognosis for early-stage cervical cancer patients with high-risk factors treated with surgery and postoperative CCRT. In clinical practice, patients with high CONUT score should be considered to receive consolidation chemotherapy.

Postoperative Nutritional Status is Predictive of the Survival Outcomes in Patients Undergoing Resection of Stage III Colorectal Cancer.

Preoperative nutritional status is reportedly associated with the clinical outcomes in patients with colorectal cancer (CRC), although it remains inconclusive whether the preoperative nutritional status that may improve after surgery is truly predictive of the survival outcomes of patients with CRC. Clinical records of patients with stage III CRC (n = 821) in whom curative resection had been achieved were retrospectively reviewed and the prognostic impact of nutritional status, determined by the controlling nutritional status (CONUT) score, was analyzed. The CONUT undernutrition grade was significantly associated with the overall survival rate (OS) in the original population (P < 0.0001). By adopting a cut-off value of CONUT score of ≥ 2 and adjustment for clinical variables using the inverse probability treatment weighting methods, the group with a preoperative CONUT score of ≥ 2 showed a worse OS as compared to the groups with a preoperative CONUT score of < 2 (P = 0.037). However, sub-analysis based on the dynamic changes in the CONUT score revealed that sustained malnutrition in the postoperative period was more frequent among patients with preoperative CONUT score of ≥ 2, and that the OS and recurrence-free survival rate (RFS) were significantly correlated with the "postoperative" nutritional status, irrespective of the preoperative nutritional status. Patients who showed improvements of the nutritional status after surgery showed a significantly longer OS and RFS. Sustained undernutrition or worsening of the nutritional status after colectomy may be associated with a worse OS and RFS after curative resection in patients with stage III CRC.

Impact of the controlling nutritional status score on severe postoperative complications of pancreaticoduodenectomy for pancreatic cancer.

The controlling nutritional status (CONUT) score is a useful biomarker to evaluate undernutrition. However, there have been few reports describing the correlation between postoperative complications and the CONUT score for pancreatic cancer. Therefore, this study aimed to assess the impact of the CONUT score on the postoperative complications of pancreaticoduodenectomy (PD) in patients with pancreatic cancer. We retrospectively analyzed 206 consecutive patients with pancreatic cancer who underwent PD over a 12-year duration at our institution. The patients were divided into two groups based on preoperative CONUT scores; their clinicopathological characteristics and surgical outcomes were compared. Furthermore, we compared the CONUT score with preoperative clinical factors and several nutritional biomarkers for postoperative complications using univariate and multivariate analyses. Postoperative complications of Clavien-Dindo grade ≥ IIIa and those of Clavien-Dindo grade ≥ IIIb occurred in 29 (14.1%) and 9 (4.4%) patients, respectively. The high CONUT score (≥5) group indicated that patients with an undernutrition status had a higher postoperative complication rate, poorer relapse-free survival, and overall survival rates than the low CONUT score (≤4) group. Among preoperative clinical factors, a high CONUT score was an independent risk factor for severe postoperative complications. The CONUT score may be a useful parameter in the identification of patients undergoing pancreatic surgery who are susceptible to postoperative complications.

Preoperative Controlling Nutritional Status (CONUT) score predicts short-term outcomes of patients with gastric cancer after laparoscopy-assisted radical gastrectomy

BackgroundAn emerging prediction tool, the Controlling Nutritional Status (CONUT) score, has shown good assessment ability of postoperative outcomes in cancer patients. This study evaluated the role of the preoperative CONUT score regarding the short-term outcomes of gastric cancer (GC) after laparoscopic gastrectomy.MethodsThree hundred and nine GC patients undergoing laparoscopic gastrectomy from January 2016 to June 2019 were analysed, retrospectively. The patients were divided into two groups according to the CONUT optimal cut-off value. Clinical characteristics and postoperative complications in the two groups were analysed and evaluated. Risk factors for complications were identified by univariate and multivariate analyses.ResultsA total of 309 patients underwent laparoscopic gastrectomy; 91 (29.4%) patients experienced postoperative complications. The preoperative CONUT score showed a good predictive ability for postoperative complications (area under the curve (AUC) = 0.718, Youden index = 0.343) compared with other indices, with an optimal cut-off value of 2.5. Patients with high CONUT score had a significantly higher incidence of overall complications (P < 0.001). Age, haemoglobin, C-reactive protein, red blood cell levels, CONUT scores, surgical procedure type, T1, T4, N0 and N3 pathological TNM classification, and pathological stages of I and III were associated with postoperative complications (P < 0.05). Furthermore, the preoperative CONUT score was identified as an independent risk predictor of postoperative complications (P = 0.012; OR = 2.433; 95% CI, 1.218-4.862) after multivariate analysis.ConclusionsThe preoperative CONUT score is a practical nutritional assessment for predicting short-term outcomes in GC patients after laparoscopy-assisted gastrectomy.

Controlling Nutritional Status (CONUT) Score as a New Indicator of Prognosis in Patients With Hilar Cholangiocarcinoma Is Superior to NLR and PNI: A Single-Center Retrospective Study.

BackgroundCurrently, many nutritional indicators, including controlling nutritional status score (CONUT), can be used to assess a patient’s nutritional status and have been reported as reliable predictors of multiple malignancies. However, the value of CONUT score in predicting postoperative outcomes in patients with hilar cholangiocarcinoma has not been explored. In this study, its predictive value will be discussed and compared with the known predictors the neutrophil lymphocyte ratio (NLR) and prognostic nutritional index (PNI).MethodsPreoperative CONUT scores, PNI and NLR levels of 94 Hilar cholangiocarcinoma (HCCA) patients who underwent radical-intent resection of hepatobiliary surgery in our hospital from March 2010 to April 2019 were retrospectively collected and analyzed. They were grouped according to their optimal cutoff value and the prognostic effects of patients in each group were compared respectively.ResultsCONUThigh was more frequent in patients with Clavien–Dindo classification of ≥IIIa (P = 0.008) and Bile leakage presence (P = 0.011). Kaplan-Meier curves analyzing the relationship between CONUT, PNI, and NLR values and HCCA patient survival (including total survival (OS) and recurrence-free survival (RFS) showed significant differences between groups (P <0.001). Meanwhile, multi-factor analysis found that Degree of cure, PNI, NLR, and preoperative CONUT score were independent prognostic factors for OS and RFS. The predictive power of CONUT score was higher than that of NLR and PNI based on time-dependent receiver operating Characteristic (ROC) analysis and the net reclassification index (NRI) and integrated discriminatory index (IDI) values (P < 0.05).ConclusionCONUT score may be of some clinical reference value in evaluating postoperative prognosis of HCCA patients.

Prognostic Potential of the Preoperative Controlling Nutritional Status (CONUT) Score in Predicting Survival of Patients with Cancer: A Systematic Review

The nutritional status of a patient has prognostic potency concerning short- and long-term outcomes, including survival, in many diseases. The controlling nutritional status (CONUT) score is a method for assessing nutritional status and predicting outcomes of several diseases. This study sought to systematically identify the prognostic role of preoperative CONUT score on posttreatment overall survival (OS), recurrence-free survival (RFS), and cancer-specific survival (CSS) in patients with cancer. The PubMed, SCOPUS, and Google Scholar databases and Google were searched for all dates until December 2019. Original articles investigating the association of preoperative CONUT score with survival in cancer patients who underwent surgery were included. Duplicate and irrelevant reports were screened out and the remaining articles assessed for quality and data extracted during critical analysis. Results of multivariate analysis were used to evaluate the prognostic competence of CONUT score in predicting survival. The search method identified an initial 181 articles, of which 32 were included in the final analysis. Lower OS, CSS, and RFS rates were reported by 100%, 100%, and 87.0% of the included studies, respectively, in cancer patients with high CONUT scores. A prognostic role of the CONUT score for prediction of OS, CSS, and RFS in cancer patients was shown by 91.7%, 90.9%, and 52.6% of the studies, respectively. The receiver operating characteristic curve area under the curve (AUC) value of the CONUT score for predicting OS, CSS, and RFS was at an acceptable level (>0.5) in all studies with available AUC values (n=19). Sixty percent (12 of 20) of the studies reported that high CONUT score was significantly related to lower BMI. The findings promote confidence that a high preoperative CONUT score is associated with poor survival rate and is an independent prognostic factor of OS and CSS in patients with various types of cancer. Evaluation of the preoperative CONUT score might help clinicians in decision-making with respect to surgical implications.

Prognostic significance of the Controlling Nutritional Status (CONUT) score in predicting postoperative complications in patients with Crohn\u2019s disease

Preoperative immune-nutritional status is correlated with postoperative outcomes. The Controlling Nutritional Status (CONUT) score is a useful tool for predicting the postoperative outcomes of cancer surgery. This study aimed to evaluate whether the CONUT score could predict postoperative complications in Crohn’s disease (CD) patients. In total, 202 CD patients were eligible. Univariate and multivariate analyses were performed to identify risk factors for postoperative complications. Receiver operating characteristic (ROC) curves were generated to examine the cutoff value for predictors of postoperative complications. Among all the patients, 66 developed postoperative complications. The cut-off value of the CONUT score was 3.5 for complications. Eighty-one patients had a low CONUT score (< 3.5), and 121 patients had a high CONUT score (> 3.5). There was a significant difference in postoperative complications between the groups with low and high CONUT score (17.3% vs. 43.0%, p < 0.001). Patients with high CONUT score had low body mass index (BMI), more mild postoperative complications (p = 0.001) and a longer postoperative stay (p = 0.002). Postoperative complications were correlated with BMI, preoperative albumin, the preoperative CONUT score, and preoperative infliximab use. Then, the preoperative CONUT score was an independent risk factor for complications (OR 3.507, 95% CI 1.522–8.079, p = 0.003). ROC analysis showed that the CONUT score was a better predictor of postoperative complications in CD patients than albumin and the prognostic nutritional index. Thus, a preoperative CONUT score cut-off value of more than 3.5 could help to identify patients with a high possibility of malnutrition and postoperative complications.

Prognostic Significance of Preoperative Controlling Nutritional Status Score in Patients Who Underwent Hepatic Resection for Hepatocellular Carcinoma.

Malnutrition is common in patients with hepatocellualar carcinoma (HCC), and is associated with postoperative complications after hepatectomy, and also increased mortality. However, there is currently no recommendation for assessment of nutritional status in HCC patients. The controlling nutritional status (CONUT) score has been correlated with prognosis in gastrointestinal cancer patients, but there are few reports on the prognostic significance of the CONUT score in patients who underwent hepatectomy for HCC. Existing results show that patients with high CONUT scores who undergo hepatectomy for HCC have poorer survival outcomes, and experience more complications than other patients. In this paper, we review the literature, and reveal that patients who underwent hepatectomy for HCC with high preoperative CONUT scores had poorer outcomes than those with low CONUT scores. Therefore, we conclude that a preoperative CONUT score may be useful for prognostic prediction in patients with HCC undergoing curative hepatectomy.

Preoperative controlling nutritional status (CONUT) score predicts long-term outcomes in patients with non-B non-C hepatocellular carcinoma after curative hepatic resection.

The controlling nutritional status (CONUT) score has been reported to predict outcomes in patients with hepatocellular carcinoma (HCC). However, the prognostic significance of the CONUT score in patients with non-B non-C (NBNC) HCC remains to be established. The study comprised 246 patients who had undergone elective hepatic resection for HCC between April 2003 and October 2017. We retrospectively investigated the relation between preoperative CONUT score as well as clinicopathological characteristics and disease-free survival (DFS) as well as overall survival (OS). In univariate analyses, CONUT score was associated with DFS and OS in patients with NBNC-HCC (p ≤ 0.01), while there was no significant association of CONUT score with DFS and OS in patients with HBV- and HCV-related HCC (p ≥ 0.1). Of the 111 patients with NBNC-HCC, 97 (87.4%) had CONUT score ≤ 3 (low CONUT score) and the other 14 (12.6%) had CONUT score ≥ 4 (high CONUT score). In the patients with NBNC-HCC, multivariate analysis identified age ≥ 65 years (p = 0.03), multiple tumors (p < 0.01), and high CONUT score (p = 0.03) as the independent and significant predictors of DFS, while multiple tumors (p = 0.01), microvascular invasion (p < 0.01), and high CONUT score (p = 0.01) were the independent and significant predictors of OS. The CONUT score seems to be a reliable and independent predictor of both DFS and OS after hepatic resection for NBNC-HCC.

Use of preoperative controlling nutritional status (CONUT) score as a better prognostic marker for distal cholangiocarcinoma after pancreatoduodenectomy.

The controlling nutritional status (CONUT) score can be easily calculated from the serum albumin concentration, total cholesterol concentration, and total lymphocyte count. The study aim was to assess the preoperative prognostic factors for the overall survival (OS) of distal cholangiocarcinoma (DCC) following pancreatoduodenectomy (PD) and to demonstrate the utility of the CONUT score. A total of 149 consecutive patients who underwent PD for DCC between September 2002 and December 2016 were divided into a low-CONUT (LC) group (CONUT scores ≤ 2) and a high-CONUT (HC) group (CONUT scores ≥ 3). The clinicopathological characteristics and OS of the patients were evaluated retrospectively. Prognostic factors of DCC were identified by multivariate analyses. The LC and HC groups included 113 and 36 patients, respectively. The OS was better in the LC group than in the HC group (median survival time and 5year survival rate: 82months and 56.8% vs. 38months and 27.6%, P = 0.005). Multivariate analyses for the OS in all patients showed that the tumor differentiation, perineural invasion, residual tumor status, portal vein resection, blood transfusion, and preoperative CONUT score ≥ 3 were independently associated with a poor survival. The CONUT score may be a useful preoperative factor for predicting the long-term survival in patients with DCC.

Prognostic value of preoperative controlling nutritional status in patients with glioblastoma

ObjectiveAccumulating evidence has demonstrated a correlation of preoperative controlling nutritional status (CONUT) score with prognosis in several malignancies, but only few studies have explored the influence of preoperative COUNT score in glioblastoma multiforme (GBM). Therefore, this study aimed to validate the connection between the clinical outcome of patients with GBM and the preoperative CONUT score. Materials and methodsThis study retrospectively evaluated the preoperative CONUT scores of 94 patients with GBM undergoing surgery between December 2015 and May 2018. The cutoff value of the CONUT score was determined using the X-tilesoftware. The influence of preoperative CONUT score on overall survival rate was calculated using the Kaplan–Meier method and Cox proportional hazard regression model. ResultsThe optimal preoperative CONUT score cutoff level was 4, and patients were divided into either low-CONUT score (<4, n = 78, 82.98 %) or high-CONUT score (≥4, n = 16, 17.02 %) groups. After univariate analysis, high-CONUT scores were closely associated with decreased overall survival (hazard ratio [HR]: 2.581, 95 % confidence interval [CI]: 1.475–4.516, p = 0.001). After multivariate analysis, this relationship continued to remain significant (HR: 3.110, 95 % CI: 1.724–5.611, p < 0.001). ConclusionsCurrent research indicates that the preoperative CONUT score has potential application as a predictor of prognosis in patients with GBM. Thus, it is important that patients with GBM undergo perioperative nutrition interventions according to their CONUT scores, which would be an effective treatment plan to improve their survival and prognosis.

Prediction of postoperative pulmonary complications using preoperative controlling nutritional status (CONUT) score in patients with resectable non-small cell lung cancer

Postoperative pulmonary complications (PPCs) significantly impact surgical outcome. We investigated the predictive ability of controlling nutritional status (CONUT) for PPC after lung resection in patients with non-small cell lung cancer (NSCLC). We retrospectively reviewed data of 922 patients with NSCLC who underwent complete resection from January 2016–December 2017. We analyzed the frequency and characteristics of PPCs and compared receiver operating characteristic (ROC) curves of various prognostic models to predict PPCs. A CONUT score higher than 1 was considered as a high CONUT score. Total incidence of PPCs was 8.6% (n = 79). The proportion of pneumonia was significantly larger in the high CONUT group (P < 0.05). The CONUT consistently had a higher area under curve (AUC) value (0.64) than other prognostic models (prognostic nutritional index (PNI): AUC = 0.61, Glasgow prognostic score (GPS): AUC = 0.57, and assessment of respiratory risk in surgical patients in Catalonia (ARISCAT): AUC = 0.54). Multivariate analysis identified underweight [Odds ratio (OR) = 4.57, P = 0.002] and high CONUT score (OR = 1.91, P = 0.009) as independent PPCs prognostic factors. One-year mortality rate for high CONUT score was significantly higher (hazard ratio = 7.97; 95% confidence interval, 1.78–35.59). Preoperative CONUT score is an independent predictor of PPCs and 1-year mortality in patients with resectable NSCLC.

The Controlling Nutritional Status (CONUT) Score as a prognostic factor for obstructive colorectal cancer patients received stenting as a bridge to curative surgery.

The Controlling Nutritional Status (CONUT) Score, originally developed as a nutritional screening tool, is a cumulative score calculated from the serum albumin level, total cholesterol level, and total lymphocyte count. Previous studies have demonstrated that the score has significant prognostic value in various malignancies. We investigated the relationship between the CONUT score and long-term survival in obstructive colorectal cancer (OCRC) patients who underwent self-expandable metallic colonic stent placement and subsequently received curative surgery. We retrospectively analyzed 57 pathological stage II and III OCRC patients between 2013 and 2019. The associations between the preoperative CONUT score and clinicopathological factors and patient survival were evaluated. A receiver operating characteristic curve analysis revealed that the optimal cut-off value for the CONUT score was 7. A CONUT score of ≥ 7 was significantly associated with elevated CA19-9 level (p = 0.03). Multivariate analyses revealed that a CONUT score of ≥ 7 was independently associated with cancer-specific survival (hazard ratio [HR] = 10.2, 95% confidence interval [CI] 1.2-85.9, p = 0.03) and disease-free survival (HR = 7.1, 95% CI 2.3-21.7, p = 0.0006). The results demonstrated that the CONUT score was a potent prognostic indicator. Evaluating the CONUT score might result in more precise patient assessment and tailored treatment.
