Length of Stay Prediction Models for Oral Cancer Surgery: Machine Learning, Statistical and ACS-NSQIP. Laryngoscope 2024. [PMID: 38651539 DOI: 10.1002/lary.31443] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 03/17/2024] [Accepted: 03/27/2024] [Indexed: 04/25/2024]
Abstract
OBJECTIVE Accurate prediction of hospital length of stay (LOS) following surgical management of oral cavity cancer (OCC) may be associated with improved patient counseling, hospital resource utilization and cost. The objective of this study was to compare the performance of statistical models, a machine learning (ML) model, and The American College of Surgeons National Surgical Quality Improvement Program's (ACS-NSQIP) calculator in predicting LOS following surgery for OCC. MATERIALS AND METHODS A retrospective multicenter database study was performed at two major academic head and neck cancer centers. Patients with OCC who underwent major free flap reconstructive surgery between January 2008 and June 2019 surgery were selected. Data were pooled and split into training and validation datasets. Statistical and ML models were developed, and performance was evaluated by comparing predicted and actual LOS using correlation coefficient values and percent accuracy. RESULTS Totally 837 patients were selected with mean patient age being 62.5 ± 11.7 [SD] years and 67% being male. The ML model demonstrated the best accuracy (validation correlation 0.48, 4-day accuracy 70%), compared with the statistical models: multivariate analysis (0.45, 67%) and least absolute shrinkage and selection operator (0.42, 70%). All were superior to the ACS-NSQIP calculator's performance (0.23, 59%). CONCLUSION We developed statistical and ML models that predicted LOS following major free flap reconstructive surgery for OCC. Our models demonstrated superior predictive performance to the ACS-NSQIP calculator. The ML model identified several novel predictors of LOS. These models must be validated in other institutions before being used in clinical practice. LEVEL OF EVIDENCE Level 3 Laryngoscope, 2024.

[PMID: 38501382 DOI: 10.1002/ohn.706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 01/26/2024] [Accepted: 02/05/2024] [Indexed: 03/20/2024]
Abstract
OBJECTIVE Nutritional and inflammatory statuses have been associated with complications in microvascular-free flaps during head and neck surgeries. This study aimed to evaluate the potential of nutritional indicators in predicting postoperative free flap complications. STUDY DESIGN We conducted a 20-year retrospective, case-control study within a defined cohort. SETTING The study involved head and neck cancer patients from the Chang Gung Research Database who underwent simultaneous tumor ablation and free flap wound reconstruction between January 1, 2001, and December 31, 2019. METHODS We employed logistic regression and stratified analysis to assess the risk of free flap complications and the subsequent need for flap revision or redo in relation to nutritional indicators and other clinical variables. RESULTS Of the 8066 patients analyzed, 687 (8.5%) experienced free flap complications. Among these, 197 (2.4%) had free flap failures necessitating a redo of either a free flap or a pedicled flap. Beyond comorbidities such as chronic obstructive pulmonary disease, end-stage renal disease, and a history of prior radiotherapy, every 10-unit decrease in the preoperative prognostic nutritional index (PNI) was consistently associated with an increased risk of both free flap complications and failure. The covariate-adjusted odds ratios were 1.90 (95% confidence interval [CI]: 1.42-2.54) and 1.89 (95% CI: 1.13-3.17), respectively. CONCLUSION A lower preoperative PNI suggests a higher likelihood of microvascular free flap complications in head and neck surgeries. Further randomized controlled trial designs are required to establish causality.

Abstract
In individuals who have sustained maxillofacial trauma, inadequate nutrition is often a sequela and may lead to complications. The purpose of this study was to investigate the association between preoperative laboratory values and postoperative complications in patients with maxillofacial trauma requiring surgical intervention. A retrospective cohort study of patients with maxillofacial trauma requiring surgical repair from 2014 to 2020 was performed at a single academic Level I Trauma Center. The primary predictor variables were preoperative laboratory values including serum albumin, white blood cell count, absolute neutrophil count, and lymphocyte count. Complications related to surgical reconstruction of facial injuries represented the primary outcome variable. The patient cohort included 152 patients, of whom 50 (32.9%) were female. When controlling for all other variables, female gender (odds ratio=2.08, 95% confidence interval, 1.02-4.21; P =0.04) and number of procedures performed ( P =0.02) were the only statistically significant predictors of postoperative complications. There were no significant differences between the complication groups for age ( P =0.89), injury severity score ( P =0.59), hospital length of stay ( P =0.30), serum albumin ( P =0.86), hemoglobin ( P =0.06), white blood cell count ( P =0.20), absolute neutrophil count ( P =0.95), lymphocyte count ( P =0.23), or absolute neutrophil/lymphocyte count ratio ( P =0.09). In this study, it was found that only gender and the number of procedures performed significantly predicted postoperative complications, while preoperative nutritional laboratory values did not. Further study with a larger cohort of patients is likely required.

[PMID: 37620245 DOI: 10.1016/j.jcms.2023.08.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 01/09/2023] [Accepted: 08/14/2023] [Indexed: 08/26/2023] Open
Abstract
This study aimed to evaluate the association between preoperative flurbiprofen, a non-selective COX inhibitor, and reoperation for flap crisis after free flap reconstruction. In this retrospective study, patients who underwent head and neck surgery with free flap reconstructions were collected. To identify risk factors for reoperation from demographic features and perioperative variables, univariate and multivariate logistic analyses were conducted. After propensity score matching (PSM), univariate and adjusted multivariate analyses were employed to explore the impact of preoperative flurbiprofen on reoperation after free flap reconstruction. This study comprised 437 patients, 33 of whom underwent reoperations for flap crisis. After multivariate analysis, radiotherapy history (P = 0.005; odds ratio [OR] = 0.225; 95% CI, 0.080-0.636) and preoperative flurbiprofen (P = 0.038; OR = 5.059; 95% CI, 1.094-23.386) were identified as independent factors for reoperation. PSM was achieved, and preoperative flurbiprofen was found to diminish the reoperation rate (P = 0.046; OR = 4.765; 95% CI, 1.029-22.202) without increasing bleeding complications. Within the limitations of the study, flurbiprofen should be administered preoperatively to reduce the rate of reoperations for flap crisis whenever appropriate.

Abstract
Investigation of the relationship between urethrocutaneous fistula (UCF) development and haematological parameters after hypospadias surgery was aimed for in this study. Patients who underwent tubularized incised plate urethroplasty between January 2015 and June 2021 with the diagnosis of distal hypospadias were included in the study. We divided the participants into two groups based on UCF development. We compared haematological parameters, including neutrophil, lymphocyte, and platelet counts; neutrophil-lymphocyte ratio (NLR); platelet-lymphocyte ratio (PLR); and systemic immune inflammation index (SII) values between the two groups. A total of 78 patients were included in the study. Of the patients, 11 developed UCF. The mean age of the patients was 74.9 ± 42.8 months. Catheter diameter, operation time, neutrophil counts, NLR, and SII values were similar between those with and without UCF (p > 0.05). However, the UCF group had significantly higher lymphocyte and platelet counts than those without UCF (p < 0.05). Moreover, the PLR value was significantly lower in the UCF group (p < 0.05). Patients who developed UCF post hypospadias surgery had a significant association with altered blood cell counts, including increased lymphocytes and decreased PLR rate. The PLR can be used as a biological marker for UCF development.

Abstract
Objective To analyze the therapeutic effect of Compound Phellodendron decoction on wounds after anal fistulotomy. Methods 100 patients with anal fistula who underwent anal fistulotomy from April 2019 to April 2021 were included in the study group and control group according to the random number table method. 50 patients in the study group were treated with Compound Phellodendron decoction by fumigation and sitting bath, while warm water replaced Compound Phellodendron decoction in the control group. Perianal pain, wound edema, and exudation were scored on postoperative days 3 and 7, and wound healing time was recorded. Interleukin-2(IL-2), IL-5, IL-6, and IL-12 were measured via a double-antibody sandwich enzyme-linked immunosorbent assay. Hematoxylin-eosin (HE) staining and immunofluorescence were used to quantitatively analyze the capillary number and CD4+ and CD8+ lymphocytes in granulation tissue on postoperative days 7. Results The scores of pain, edema, and exudation in 2 groups on postoperative day 7 were lower than those on the 3rd postoperative day. Compared with the control group, the pain, edema, and exudation scores in the study group were decreased, and the wound healing time was shortened; the expressions of IL-2 and IL-12 in the study group were significantly increased, while the expressions of IL-5 and IL-6 were decreased; the number of capillaries and CD4+ lymphocytes in the study group was increased, while the number of CD8+ lymphocytes was decreased. Conclusion Compound Phellodendron decoction had efficacy in promoting wound healing, reducing complications, and changing lymphocyte aggregation and alleviating local inflammatory response.

Abstract
(1) Background: Hand-assisted laparoscopic surgery for liver resection is a globally established technique. In this study, we report on the incidence and risk factors for postoperative incisional hernia (IH) after hand-assisted laparoscopic surgery for colorectal liver metastasis. (2) Methods: This was retrospective analysis of 89 consecutive hand-assisted laparoscopic surgery for colorectal liver metastasis. (3) Results: Participants were 39 females and 50 males. Median age was 65 years, and in 63%, the BMI was ≥25. Postoperative complications were encountered in 18% of the patients. Seven patients (7.8%) had postoperative incisional hernia in the hand port site. There was significantly higher incidence of incisional hernia in overweight patients (BMI ≥ 25) (p = 0.04), and in cases with simultaneous liver and colon resection (p = 0.02). In univariant and multivariant analyses, simultaneous liver and colon resection (p = 0.004 and 0.03, respectively), and platelet-to-lymphocyte ratio ≤ 200 (p = 0.03, 0.04, respectively) were both independent risk factors for developing postoperative incisional hernia. (4) Conclusions: Both simultaneous liver and colon resection, and platelet-to-lymphocyte ratio ≤ 200 are independent risk factors for postoperative incisional hernia after hand-assisted laparoscopic surgery for colorectal liver metastasis.

Preoperative neutrophil-to-lymphocyte ratio predicts healing time for postoperative pancreatic fistula after distal pancreatectomy. Ann Gastroenterol Surg 2022; 6:169-175. [PMID: 35106427 PMCID: PMC8786688 DOI: 10.1002/ags3.12510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 08/31/2021] [Accepted: 09/06/2021] [Indexed: 11/06/2022] Open
Abstract
PURPOSE Postoperative pancreatic fistula is a serious complication of distal pancreatectomy. Although many studies have described the incidence and risk factors associated with postoperative pancreatic fistula (POPF), few have focused on the healing time. This study investigated the healing time and potential factors associated with the healing time of POPF after distal pancreatectomy (DP). METHODS Among 114 patients that underwent DP in our hospital from January 2010 to December 2020, we included 88 that developed POPF. The healing time for a postoperative pancreatic fistula was defined as the interval between the completion of DP and the removal of all drains related to the treatment for POPF. Based on the definition, three cases who required additional treatment after removal of all drains were excluded from this study. Clinical factors associated with the fistula healing times were investigated in the 85 patients. RESULTS The average POPF healing time was 11 ± 10 days (median: 6 days, range: 3-57). We found that the neutrophil-to-lymphocyte ratio, a marker of inflammatory and nutritional status, was the only factor independently associated with the POPF healing time; the mean healing time was significantly shorter in patients with neutrophil-to-lymphocyte ratio ≤2.1 (8 ± 6 days) than in those with neutrophil-to-lymphocyte ratio >2.1 (13 ± 12 days; P = .0139). CONCLUSION We demonstrated that the neutrophil-to-lymphocyte ratio could independently predict the POPF healing time after DP. These findings suggested that improving the neutrophil-to-lymphocyte ratio might shorten the healing times for POPF after DP.

Systemic Inflammatory Markers as Predictors of Postoperative Complications and Survival in Patients With Advanced Head and Neck Squamous Cell Carcinoma Undergoing Free-Flap Reconstruction. J Oral Maxillofac Surg 2021; 80:744-755. [PMID: 35032441 DOI: 10.1016/j.joms.2021.12.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 12/12/2021] [Accepted: 12/15/2021] [Indexed: 01/21/2023]
Abstract
PURPOSE The aim of this study was to determine the prognostic value of systemic inflammatory indices as factors for postoperative complications and survival in patients with advanced stages of p16-negative head and neck squamous cell carcinoma undergoing free-flap reconstruction. METHODS This was a retrospective cohort study. The primary predictor variables were inflammatory markers such as neutrophil, lymphocyte, monocyte, and platelet count, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio, lymphocyte-monocyte ratio, derived NLR, systemic immune-inflammation, and systemic inflammatory marker index (SIM). Multivariate regression analyses were used to measure the associations between systemic inflammatory indices and overall and disease-free survival as a primary outcome and occurrence of postoperative complications as a secondary outcome measure. RESULTS The sample was composed of 69 male (76.67%) and 21 female (23.33%) patients, with an average age of 61.15 ± 9.79 years. The median follow-up time was 24 months, and 73 of 91 (66.43%) patients were alive during the median follow-up. Overall disease survival correlated with systemic immune-inflammation (P = .022, cutoff >1,005.3, sensitivity 67.1%, and specificity 70.6%) and SIM (P = .0001, cutoff >4.05, sensitivity 90.4%, and specificity 41.2%), preoperative platelets (P = .036, cutoff <194, sensitivity 28.8%, and specificity 94.1%), and postoperative lymphocytes (P = .012, cutoff <0.6, sensitivity 38%, and specificity 76.5%), whereas increased SIM (P = .042, cutoff >4.05, sensitivity 91.3%, and specificity 38.1%), NLR (P = .031, cutoff >13.2, sensitivity 56.9%, and specificity 60%), and preoperative platelets (P = .006, cutoff <244, sensitivity 52.3%, and specificity 76%) were associated with adverse disease-free survival. The cumulative postoperative complication rate was 34.5%, of which 13.3% accounted for major complications, whereas derived NLR (P = .013, DF 1, χ2 test 6.161, cutoff >2.3) and postoperative lymphocytes (P = .009, DF 1, χ2 test 6.756, cutoff <1) correlated with occurrence of complications. CONCLUSIONS Inflammatory indices as measures of inflammation-related systemic dysfunction may be associated with adverse survival in patients with head and neck squamous cell carcinoma and occurrence of postoperative complications and with specific cutoff values.

Utility of preoperative systemic inflammatory biomarkers in predicting postoperative complications after pancreaticoduodenectomy: Literature review and single center experience. World J Gastrointest Surg 2021; 13:1216-1225. [PMID: 34754389 PMCID: PMC8554715 DOI: 10.4240/wjgs.v13.i10.1216] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Revised: 05/10/2021] [Accepted: 07/13/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The role of preoperative inflammatory biomarkers (PIBs) in predicting postoperative morbidity has been assessed in colorectal and otorhinolaryngeal surgery. However, data regarding the role that preoperative inflammatory biomarkers have on morbidity after pancreaticoduodenectomiy (PD) are less consistent.
AIM To assess the utility of PIBs in predicting postoperative complications after pancreaticoduodenectomy.
METHODS A database of 317 consecutive pancreaticoduodenectomies performed from April 2003 to November 2018 has been retrospectively analyzed. Data regarding preoperative neutrophil-to-lymphocyte ratio (NLR), derived NLR and C-reactive protein (CRP), and postoperative complications of 238 cases have been evaluated. Exclusion criteria were: age < 18-years-old, previous neoadjuvant treatment, absence of data about PIBs, concomitant hematological disorders, and presence of active infections at the moment of the surgery. PIBs were compared using Mann-Whitney’s test and receiver operating characteristic (ROC) analysis was performed to define the cutoffs. The positive predictive value (PPV) was computed to evaluate the probability to develop complication. P-values < 0.05 were considered statistically significant.
RESULTS According to the literature findings, only four papers have been published reporting the relation between the inflammatory biomarkers and PD postoperative morbidity. A combination of preoperative and postoperative inflammatory biomarkers in predicting complications after PD and the utility of preoperative NLR in the development of postoperative pancreatic fistula (POPF) have been reported. The combination of PIBs and postoperative day-1 drains amylase has been reported to predict the incidence of POPF. According to our results, CRP values were significantly different between patients who had/did not have postoperative complications and abdominal collections (P < 0.05). Notably, patients with preoperative CRP > 8.81 mg/dL were at higher risk of both overall complications and abdominal collections (respectively P = 0.0037, PPV = 0.95, negative predictive value [NPV] = 0.27 and P = 0.016, PPV = 0.59, NPV = 0.68). Preoperative derived neutrophil-to-lymphocyte ratio (dNLR) (cut off > 1.47) was also a predictor of abdominal collection (P = 0.021, PPV = 0.48, NPV = 0.71). Combining CRP and dNLR, PPV increased to 0.67. NLR (cut off > 1.65) was significantly associated with postoperative hemorrhage (P = 0.016, PPV = 0.17, NPV = 0.98).
CONCLUSION PIBs may predict complications after PD. During postoperative care, PIB levels could influence decisions regarding the timing of drains removal and the selection of patients who might benefit from second level diagnostic exams.

Prediction of the Postoperative Fat Volume Retention Rate After Augmentation Mammoplasty with Autologous Fat Grafting: From the Perspective of Preoperative Inflammatory Level. Aesthetic Plast Surg 2021; 46:2488-2499. [PMID: 34599352 DOI: 10.1007/s00266-021-02604-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Accepted: 09/16/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Postoperative fat volume retention rate (PFVRR) after augmentation mammoplasty with autologous fat grafting is highly variable on an individual basis and challenging to be predicted. However, at present, there is a lack of further research on the relevant preoperative patient's self-related influencing factors. The early inflammatory response degree, directly influenced by preoperative inflammatory level, is an indispensable part of angiogenesis, which is a key factor in adipocyte survival. METHODS A retrospective review was conducted of patients who underwent breast augmentation with autologous fat grafting performed by a senior surgeon. Preoperative patient demographics and laboratory findings relevant to inflammatory level, such as monocyte to lymphocyte ratio (MLR), were included as the independent variables. The PFVRR more than 3 months after the operation was included as the dependent variable. Key factors influencing the PFVRR were analyzed. RESULTS Sixty-three patients were included. The total volume of bilateral fat injection was 375.00 (range, 320.00-400.00) mL, and the long-term bilateral volumetric change was 106.98 (range, 69.90-181.58) mL. The mean PFVRR was 35.36% ± 15.87%, and the preoperative MLR was an independent positive influencing factor of it, while the lymphocyte (L) count was negative. By ROC curve analysis, a value of MLR equal to 0.23 was the diagnostic cut-off point for whether PFVRR was greater than 50%, and its area under the curve was 0.870, with a sensitivity of 93.33% and a specificity of 81.25%. The other hematological parameters and demographics such as age, body mass index, and donor site were not significantly correlated with the PFVRR. CONCLUSION Preoperative peripheral blood inflammatory indicators can influence the PFVRR, with the MLR positively and L count negatively. Based on the diagnostic threshold of MLR = 0.23 derived from this study, clinicians can make reasonable predictions of whether half of the injected fat volume would be retained based on preoperative blood routine tests that are readily available.

Abstract
Wound necrosis and secondary infection are common complications after Naja atra bites. Clinical tools to evaluate the infection risk after Taiwan cobra bites are lacking. In this Cobra BITE study, we investigated the prevalence of wound infection, bacteriology, and corresponding antibiotic usage in patients presenting with Taiwan cobra snakebites. Patients with wound infection lacking tissue necrosis were included in developing Cobra BITE score utilizing univariate and multiple logistic regression, as patients with wound necrosis require antibiotics for infection treatment. 8,295,497 emergency department visits occurred in the span of this study, with 195 of those patients being diagnosed as having cobra bites. Of these patients, 23 had wound necrosis, and 30 had wound infection, resulting in a wound infection rate of 27.2% (53/195). Enterococcus faecalis and Morganella morganii were the main bacteria identified in the culture report regardless of whether patients’ wounds had necrosis. As per our Cobra BITE score, the three factors predicting secondary wound infection after cobra bites are hospital admission, a white blood cell count (in 103/µL) × by neu-trophil-lymphocyte ratio value of ≥114.23, and the use of antivenin medication. The area under the receiver operating characteristic curve for the Cobra BITE score system was 0.88; ideal sensitivity and specificity were 0.89 and 0.76. This scoring system enables the assessment of wound infections after N. atra bites, and it could be modified and improved in the future for other Naja spp. bites.

Abstract
Malnutrition is common among patients who have oral cavity squamous cell carcinoma (OSCC), but its effect on the incidence of postoperative complications remains uncertain. Validated nutrition and complication assessment tools were used to evaluate the effects of nutrition on the likelihood of postoperative complications after curative surgery for OSCC.A retrospective study that spanned January 2014 to December 2018 enrolled 70 patients who received curative surgery for OSCC. Nutritional status before surgery was evaluated with the scored Patient-Generated Subjective Global Assessment (PG-SGA), and patients were classified as either well-nourished (rating A) or malnourished (ratings B and C). Complications 30 days after the operation were graded using Clavien-Dindo classification. The perioperative clinicopathological characteristics of the groups were compared, and risk factors for postoperative complications were identified through logistic regression.A total of 44 (62.8%) patients formed the malnourished group, and they tended to be older (P = .03), weigh less (P = .001), have lower Body Mass Index (P = .003), higher PG-SGA scores (P < .001), higher neutrophil-to-lymphocyte ratio (P = .034), more postoperative complications (P < .001), and longer hospital stays (P = .021). Major complications (Clavien-Dindo classification ≥ IIIa) were experienced by 18.5% (n = 13) of patients and were more common in the malnourished group (P = .007). Multivariate logistic regression demonstrated that PG-SGA score ≥4 was an independent risk factor for postoperative complications (hazard ratio = 4.929, P = .008).Malnutrition defined using the PG-SGA is an independent risk factor for postoperative complications of curative surgery in patients with OSCC. More prospective studies are warranted to confirm our findings.

Abstract
We aimed to describe the prevalence of postoperative complications and evaluate its relationship with underweight, obesity, preoperative nutritional status, and systemic inflammation status in patients undergoing microvascular reconstruction for oral and maxillofacial cancer. Patients who were ≥20 years old and underwent microvascular reconstruction surgery between January 2009 to June 2019 were investigated. Patient demographics including body mass index, prognostic nutritional status, and neutrophil-lymphocyte ratio were collected. Logistic regression analysis was applied to evaluate these impacts on postoperative complications. A postoperative complication was defined as a Clavien-Dindo classification more than or equal to II. Of the 145 patients included in the analysis, 83 patients (57.2%) experienced postoperative complications, belonging to a Clavien-Dindo classification Ⅱ (n=71), Ⅲb (n=11), and Ⅳa (n=1). Multiple logistic regression revealed that a body mass index less than 18.5 kg/m2 (odds ratio 6.19, 95% confidential interval 1.34-28.6, P=0.02) was related to postoperative complications. Another multiple logistic regression model including all explanatory factors found that underweight (P=0.03) was related to postoperative complications. This retrospective study showed that preoperative underweight was associated with postoperative complications as evaluated by the Clavien-Dindo classification.

Platelet-to-lymphocyte ratio is correlated with a delay in feeding resumption following a transhiatal esophagectomy with cervical anastomosis. World J Surg Oncol 2020; 18:267. [PMID: 33054830 PMCID: PMC7559741 DOI: 10.1186/s12957-020-02035-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Accepted: 09/22/2020] [Indexed: 12/01/2022] Open
Abstract
Introduction The lymphocytic population, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) are prognostic tools predictive of adverse outcomes for several solid tumors and oncologic surgeries, one of which is esophageal adenocarcinoma. Furthermore, delayed resumption of oral feeding postoperatively is associated with significant morbidity. Given the controversies regarding post-op nutritional support in these patients, this study investigates the prognostic role of the lymphocytic percentage, the NLR, and the PLR in predicting prolonged length of hospital stay (LOHS) and ICU stay (LOICUS) as well as delayed oral feeding following transhiatal esophagectomy (THE) for adenocarcinoma of the esophagogastric junction (AEG). Methods Forty consecutive patients who underwent transhiatal esophagectomy performed by a single surgeon for Siewert type II and type III adenocarcinoma of the esophagogastric junction at a tertiary referral center were selected. Retrospective data collection was performed from the patients’ medical records, and statistical analysis was performed using Pearson correlation and Student’s t test and Chi-square testing. Results An increased LOHS was correlated with a lower preoperative lymphocyte percentage (p = 0.043), higher NLR (p = 0.010) and PLR (p = 0.015), and an increased number of packed red blood cell (PRBC) transfusions perioperatively (p = 0.030). An increased LOICUS was correlated with a lower preoperative lymphocyte percentage (p = 0.033), higher NLR (p = 0.018) and PLR (p = 0.044), an increased number of PRBC transfusions (p = 0.001), and patients’ comorbidities (p < 0.05). A delay in feeding resumption was correlated with a lower preoperative lymphocyte percentage (p = 0.022), higher NLR (p = 0.004) and PLR (p = 0.001), an increased PRBC transfusions (p = 0.001), and diabetes mellitus (p = 0.033). Multivariate analysis with automatic linear modeling showed that only the preoperative PLR was a powerful predictor for the delay of feeding resumption (p < 0.01). Conclusion The lymphocyte percentage, PLR, and NLR are found to be associated with prolonged hospitalization and ICU stay and delayed oral feeding following THE for Siewert types II and III AEG. We hope by this series, to have set, at least one preliminary cornerstone, in the creation of a prognostic model, capable of assessing the need for an intraoperative jejunostomy placement, in patients undergoing esophagectomy for distal esophageal carcinoma.

Abstract
Intestinal anatomosis is a complex and multicellular process that involving three overlapped phases: exudative phase, proliferative phase, and reparative phase. Undisturbed anastomotic healings are crucial for the recovery of patients after operations but unsuccessful healings are linked with a considerable mortality. This time, we concentrate on the immunologic changes during different phases of intestinal anastomotic healing and select several major immune cells and cytokines of each phase to get a better understanding of these immunologic changes in different phases, which will be significant for more precise therapy strategies in anastomoses.

Preoperative systemic inflammatory biomarkers and postoperative day 1 drain amylase value predict grade C pancreatic fistula after pancreaticoduodenectomy. Ann Med Surg (Lond) 2020; 57:56-61. [PMID: 32714527 PMCID: PMC7374182 DOI: 10.1016/j.amsu.2020.07.018] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 07/10/2020] [Accepted: 07/11/2020] [Indexed: 12/19/2022] Open
Abstract
Background Postoperative day 1-drains amylase (POD1-DA) values are commonly used to predict the risk of pancreatic fistula (PF) after pancreaticoduodenectomy (PD). Perioperative inflammatory biomarkers have been associated to higher risk of complications in different oncological surgeries. Aim of this study was to investigate the utility of the combination of preoperative inflammatory biomarkers (PIBs) with POD1-DA levels in predicting grade C PF. Materials and methods From a prospective collected database of 317 consecutive pancreaticoduodenectomies, data regarding POD1-DA levels and PIBs as neutrophil-to-lymphocyte ratio (NRL), derived neutrophil-to-lymphocyte ratio (dNRL), platelet-to-lymphocyte ratio (PLR) were analyzed in 227 cases. P-values <0.05 were considered statistically significant. Receiver operating characteristic (ROC) curves defined the optimal thresholds for biomarkers and drains amylase values and their accuracy to predict PF. Furthermore, the Positive Predictive Value (PPV) was computed to evaluate the probability to develop PF combining PIBs and drains amylase values. Combination of drains amylase and different PIBs cut-offs were used to evaluate the risk of grade C PF. Results A POD1-DA level of 351 U/L significantly predicted PF (sensitivity 82.7%, specificity 76%, AUC 0.836; p < 0.001) with a PPV of 76.5% and a NPV of 82.6%. POD1-DA levels ≥807 U/L significantly predicted grade C PF (sensitivity 72.7%, specificity 64.4%, AUC 0.676; p = 0.004) with a PPV of 17.8% and a NPV of 95.6%. Notably, this last PPV increased from 17.8% to 89% when PIBs, at different cut-offs, were combined with POD1-DA at the value ≥ 807 U/L. Conclusion PIBs significantly improve POD1-DA ability in predicting grade C PF after PD. Grade C pancreatic fistula is a major complication after pancreaticoduodenectomy. Postoperative day 1-drain amylase levels is a reliable predictor of pancreatic fistula. Systemic inflammatory biomarkers and postoperative day 1-drain amylase levels may predict grade C pancreatic fistula.

Abstract
BACKGROUND Biomarkers from routine complete blood count are known predictive factors of long-term outcomes in cancer patients. The value of these biomarkers in the setting of trimodal therapy for esophageal cancer in predicting early postoperative outcomes is not studied. OBJECTIVE The present study evaluated the value of cellular blood components changes during neoadjuvant chemoradiotherapy followed by curative intent esophagectomy for cancer in predicting postoperative mortality and morbidity. METHODS A cohort of 149 consecutive patients that underwent chemoradiotherapy using platinum- and taxane-based regimens followed by esophagectomy was analyzed. Cellular components of blood collected before neoadjuvant therapy (period A) and before surgery (period B) were assessed for postoperative mortality and complications. Univariate and multivariate Cox regression models were applied to evaluate the independent prognostic significance of blood count variables. RESULTS Postoperative morbidity was present in 46% of the patients. On multiple regression analysis platelet volume (B) (OR: 1.53; 95% CI: 1.2-2.33) was an independent predictor of general complications. Severe postoperative surgical complications were present in 17% of the patients. On multiple regression analysis, lymphocyte decrease between B-A periods (OR: 0.992; 95% CI: 0.990-0.997) was related to higher risk for severe complications. Cervical anastomotic leakage was present in 25.6% of the patients. On univariate analysis eosinophil count in A and B periods was related to cervical anastomotic leakage. For this outcome, multivariate joint model could not identify independent risk variables of cellular components of blood. The 30-day mortality rate was 7.4%. On univariate analysis, platelet count in period B was associated to higher risk for mortality. The multivariate joint model could not accurately predict mortality due to the few number of patients in the mortality group. CONCLUSION This is the first study to assess the relationship between peripheral blood count variables changes during neoadjuvant chemoradiotherapy using a platinum- and taxane-based regimen followed by curative intent esophagectomy for cancer in predicting postoperative complications. The platelet volume prior to surgery is related to postoperative complications and the lymphocyte count change prior to surgery predicts severe postoperative complications in the setting of trimodal therapy for esophageal cancer.

Mol Clin Oncol 2018; 9:362-368. [PMID: 30233792 PMCID: PMC6142300 DOI: 10.3892/mco.2018.1698] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2018] [Accepted: 08/06/2018] [Indexed: 02/07/2023] Open
Abstract
Systemic inflammatory-, immunological- and nutritional-based indices, such as the neutrophil-to-lymphocyte ratio (NLR), the prognostic nutritional index (PNI) and the Glasgow prognostic score (GPS), are drawing considerable research attention to predict the long-term prognosis of many types of cancer. Recently, these parameters have also been reported to be useful in predicting postoperative morbidity in several fields, including colorectal and otolaryngological cancer. However, while distal cholangiocarcinoma exhibits a high morbidity rate, its risk factors of morbidity have not yet been established. This is because previous studies have analyzed distal cholangiocarcinoma as periampullary tumors combined with pancreatic head cancer. Therefore, the aim of the present study was to investigate the application of the NLR, the PNI and the GPS in evaluating risk factors for postoperative morbidity in patients with distal cholangiocellular or ampullary carcinoma. Eighty-four patients who underwent pancreaticoduodenectomy (PD) for distal cholangiocellular or ampullary carcinoma at the Department of Surgery in Kitasato University Hospital between 2008 and 2016 were enrolled. Associations between perioperative characteristics (NLR, PNI and GPS) and postoperative complications (Clavien-Dindo classification grade III or higher) were retrospectively analyzed. In the univariate analysis, neutrophil and lymphocyte counts, body mass index (BMI) and the NLR were associated with postoperative complications (P<0.05). In the multivariate analysis, BMI [>23.0 kg/m2; odds ratio (OR): 3.80, 95.0% confidence interval (CI): 1.35–11.83; P=0.011] and the NLR (>2.0; OR: 6.77, 95.0% CI: 2.44–21.13; P<0.001) were independent risk factors for postoperative complications. BMI and the NLR are valuable predictors of postoperative morbidity following PD in patients with distal cholangiocarcinoma. It would be beneficial to determine treatment strategies for distal cholangiocarcinoma based on the NLR to reduce postoperative complications.

Abstract
BACKGROUND The purposes of this systematic review and meta-analysis were to investigate the relationship between the neutrophil-to-lymphocyte ratio (NLR) and prognosis in head and neck cancer. METHODS A systematic review and meta-analysis were done to investigate the role of NLR in overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS), and progression-free survival (PFS). RESULTS For qualitative analysis, 33 cohorts with over 10 072 patients were included. For quantitative analysis, 15 studies were included with 5562 patients. The pooled data demonstrated that an elevated NLR significantly predicted poorer OS and DSS. CONCLUSION An elevated pretreatment NLR is a prognostic marker for head and neck cancer. It represents a simple and easily obtained marker that could be used to stratify groups of high-risk patients who might benefit from adjuvant therapy.

Abstract
BACKGROUND Surgical site infection is a complication of surgery for patients with head and neck cancer. We examined the risk factors for surgical site infection in patients undergoing surgery for head and neck cancer. METHODS The study involved 369 patients who underwent surgery for head and neck cancer. Hematological and nutritional parameters were measured preoperatively and postoperatively. Univariate and multivariate analyses were used to determine the risk factors for surgical site infection. RESULTS Of the 369 patients, 104 (28.2%) had surgical site infections: 45 (12.2%) superficial incisional; 6 (1.6%) deep incisional; and 53 (14.4%) organ/space infections. Multivariate analyses showed that history of radiotherapy, weight loss at diagnosis (>5%), preoperative hypoalbuminemia, neutrophil/lymphocyte ratio (NLR), reconstructive surgery, and tracheostomy were the independent factors predictive of surgical site infection. Patients with preoperative low serum albumin levels (<3.3 g/L) had a 3-fold higher risk of surgical site infection. CONCLUSION Our study shows that patient nutritional and hematological markers are associated with the risk of surgical site infection after major surgery for head and neck cancer.
