[PMID: 37975152 PMCID: PMC10757150 DOI: 10.1002/cam4.6712] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 11/01/2023] [Accepted: 11/06/2023] [Indexed: 11/19/2023] Open
Abstract
OBJECTIVE To investigate the prognostic significance of body composition and nutritional indicators in patients undergoing radical cystectomy with muscle-invasive bladder cancer (MIBC) and to develop a novel nomogram that accurately predicts overall survival (OS). METHODS From December 2010 to December 2020, we retrospectively collected clinical and pathological data from 373 MIBC patients who underwent radical cystectomy at our hospital. Preoperative computed tomography (CT) images were used to measure the skeletal muscle index (SMI), subcutaneous adipose index (SAI), visceral adipose index (VAI), skeletal muscle density (SMD), subcutaneous adipose density (SAD), visceral adipose density (VAD), and visceral adipose to subcutaneous adipose area ratio (VSR). The clinicopathological characteristics were evaluated using LASSO regression and multivariate Cox regression, and a nomogram was constructed to predict 1-, 3-, and 5-year overall survival. The concordance index (C-index), time-dependent receiver operating characteristic curves (t-ROC), calibration curve, and decision curve analysis (DCA) were used to assess the discriminative ability, calibration, and clinical practicality of the nomogram. RESULTS Multivariate analyses demonstrated that pT stage, lymph node status, LVI, SMD, and prognostic nutritional index (PNI) are independent prognostic factors for OS. Additionally, a nomogram was created. The nomogram's C-index was 0.714 (95% CI: 0.695-0.733). The area under the t-ROC curve of 1-, 3-, and 5-year survival corresponding to the model was 0.726, 0.788, and 0.785, respectively. The calibration curve demonstrated excellent agreement between the predicted and observed outcomes. The DCA revealed that patients with MIBC could benefit from the nomogram. CONCLUSION Based on body composition and nutritional indicators, we developed a novel nomogram with excellent predictive accuracy and reliability for predicting the prognosis of MIBC patients undergoing RC.

Abstract
BACKGROUND There is no consensus on the relation between visceral fat mass and long-term postoperative prognosis in patients with upper gastrointestinal (GI) cancer. OBJECTIVES The purpose of this study was to investigate the association of preoperative visceral fat mass with postoperative complications and overall survival (OS) in patients with upper GI cancer. METHODS We searched MEDLINE, the Cochrane Central Register of Controlled Trials, EMBASE (Dialog), the WHO International Clinical Trials Platform Search Portal, and ClinicalTrials.gov and identified observational studies published from inception through 20 July 2022. We conducted a systematic review and random-effects meta-analysis of studies including patients who were surgically treated for upper GI cancer and whose visceral fat mass was assessed on the basis of body composition. We independently assessed the risk of bias and quality of evidence using the Quality In Prognosis Studies and the Grading of Recommendations, Assessment, Development, and Evaluation approach, respectively. The primary outcome was OS. HRs and 95% CIs for OS were pooled. RESULTS Ninety-one studies (n = 20,583) were included. All studies used computed tomography (CT) to assess the body composition of patients. Twenty-four studies reported the relation between high visceral fat and postoperative outcomes, and their results were synthesized. Compared with low visceral adipose tissue, high visceral adipose tissue assessed by CT may improve OS (HR: 0.69; 95% CI: 0.55, 0.87; I2 = 65%; n = 3407). The risk of bias for OS in each study was moderate or high. The certainty of evidence for OS was very low because of inconsistency in the forest plot, the moderate or high risk of bias, and publication bias. CONCLUSIONS High visceral fat may be associated with improved OS after radical resection in patients with upper GI cancer. Further studies are needed to confirm these findings and mitigate the risk.

A novel nomogram based on the prognostic nutritional index for predicting postoperative outcomes in patients with stage I-III gastric cancer undergoing robotic radical gastrectomy. Front Surg 2022; 9:928659. [PMID: 36386538 PMCID: PMC9642802 DOI: 10.3389/fsurg.2022.928659] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 09/29/2022] [Indexed: 02/02/2024] Open
Abstract
BACKGROUND The inflammation and nutrition status are crucial factors influencing the outcome of patients with gastric cancer. This study aims to investigate the prognostic value of the preoperative prognostic nutritional index (PNI) in patients with stage I-III gastric cancer undergoing robotic radical gastrectomy combined with Enhanced Recovery after Surgery (ERAS), and further to create a clinical prognosis prediction model. STUDY 525 patients with stage I-III gastric cancer who underwent ERAS combined with RRG from July 2010 to June 2018 were included in this work, and were divided randomly into training and validating groups in a 7-to-3 ratio. The association between PNI and overall survival (OS) was assessed by Kaplan-Meier analysis and the log-rank test. Independent risk factors impacting postoperative survival were analyzed with the Cox proportional hazards regression model. A nomogram for predicting OS was constructed based on multivariate analysis, and its predictive performance was evaluated using Harrell's concordance index (C-index), calibration plots, ROC curve, decision curve analysis (DCA), and time-dependent ROC curve analysis. RESULTS Survival analyses revealed the presence of a significant correlation between low preoperative PNI and shortened postoperative survival (P = 0.001). According to multivariate analysis, postoperative complications (P < 0.001), pTNM stage (II: P = 0.007; III: P < 0.001), PNI (P = 0.048) and lymph node ratio (LNR) (P = 0.003) were independent prognostic factors in patients undergoing ERAS combined with RRG. The nomogram constructed based on PNI, pTNM stage, complications, and LNR was superior to the pTNM stage model in terms of predictive performance. The C-indexes of the nomogram model were respectively 0.765 and 0.754 in the training and testing set, while AUC values for 1-year, 3-year, and 5-year OS were 0.68, 0.71, and 0.74 in the training set and 0.60, 0.67, and 0.72 in the validation set. CONCLUSION Preoperative PNI is an independent prognostic factor for patients with stage I-III gastric cancer undergoing ERAS combined with robotic radical gastrectomy. Based on PNI, we constructed a nomogram for predicting postoperative outcomes of gastric cancer patients, which might be utilized clinically.

Study protocol for feasibility and safety of adopting early oral feeding in post total laparoscopic total gastrectomy (overlap esophagojejunostomy): A multicentre randomized controlled trial. Front Nutr 2022; 9:993896. [PMID: 36082028 PMCID: PMC9445659 DOI: 10.3389/fnut.2022.993896] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 08/08/2022] [Indexed: 12/24/2022] Open
Abstract
BackgroundTotal laparoscopic total gastrectomy (TLTG) for gastric cancer, especially with overlap esophagojejunostomy, has been verified that it has advantages of minimally invasion, less intraoperative bleeding, and faster recovery. Meanwhile, early oral feeding (EOF) after the operation has been demonstrated to significantly promote early rehabilitation in patients, particularly with distal gastrectomy. However, due to the limited application of TLTG, there is few related research proving whether it is credible or safe to adopt EOF after TLTG (overlap esophagojejunostomy). So, it is urgent to start a prospective, multicenter, randomized clinical trials to supply high level evidence.Methods/designThis study is a prospective, multicenter, randomized controlled trial with 200 patients (100 in each group). These eligible participants are randomly allocated into two different groups, including EOF group and delay oral feeding (DOF) group after TLTG (overlap esophagojejunostomy). Anastomotic leakage will be carefully observed and recorded as the primary endpoints; the period of the first defecation and exhaust, postoperative length of stay and hospitalization expenses will be recorded as secondary endpoints to ascertain the feasibility and safety of adopting EOF after TLTG (overlap esophagojejunostomy).DiscussionRecently, the adoption of TLTG was limited due to its difficult anastomotic procedure, especially in vivo esophagojejunostomy. With the innovation and improvement of operating techniques, overlap esophagojejunostomy with linear staplers simplified the anastomotic steps and reduced operational difficulties after TLTG. Meanwhile, EOF had received increasing attention from surgical clinicians as a nutrition part of enhanced recovery after surgery (ERAS), which had shown better results in patients after distal gastrectomy. Considering the above factors, we implemented EOF protocol to evaluate the feasibility and safety of adopting EOF after TLTG (overlap esophagojejunostomy), which provided additional evidence for the development of clinical nutrition guidelines.Clinical trial registration[www.chictr.org.cn], identifier [ChiECRCT20200440 and ChiCTR2000040692].
