Effect of intraoperative blood loss on postoperative complications and prognosis of patients with colorectal cancer: A meta‑analysis. Biomed Rep 2024; 20:22. [PMID: 38169991 PMCID: PMC10758914 DOI: 10.3892/br.2023.1710] [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: 09/21/2023] [Accepted: 11/15/2023] [Indexed: 01/05/2024] Open
Abstract
The purpose of the present study was to evaluate whether the amount of intraoperative blood loss (IBL) affects the complications and prognosis of patients with colorectal cancer (CRC). The PubMed, EMBASE and the Cochrane Library databases were used to search for eligible studies from inception to November 30, 2020. Hazard ratios (HRs) and 95% confidence intervals (Cls) were pooled up. The overall survival (OS) and disease-free survival (DFS) were compared between the larger IBL group and the smaller IBL group. The present study was performed with RevMan 5.3 (The Cochrane Collaboration). A total of seven studies involving 1,540 patients with CRC were included in the present study. The smaller IBL group had a higher rate of OS (HR=1.45, 95% CI=1.17 to 1.8, P=0.0007) and a higher rate of DFS (HR=1.76, 95% CI=1.40 to 2.21, P<0.00001). Furthermore, the larger IBL group had a higher rate of postoperative complications than the smaller IBL group (odds ratio=2.06, 95% CI=1.72 to 2.15, P<0.00001). In conclusion, a smaller IBL was associated with better OS and DFS, and a lower risk of postoperative complications compared with a larger IBL in patients with CRC, suggesting that surgeons should pay more attention during perioperative management and surgical operation to reduce IBL.

A Prospective Study on the Roles of the Lymphocyte-to-Monocyte Ratio (LMR), Neutrophil-to-Lymphocyte Ratio (NLR), and Platelet-to-Lymphocyte Ratio (PLR) in Patients with Locally Advanced Rectal Cancer. Biomedicines 2023; 11:3048. [PMID: 38002048 PMCID: PMC10669751 DOI: 10.3390/biomedicines11113048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 11/10/2023] [Accepted: 11/12/2023] [Indexed: 11/26/2023] Open
Abstract
Rectal cancer constitutes over one-third of all colorectal cancers (CRCs) and is one of the leading causes of cancer-related deaths in developed countries. In order to identify high-risk patients and better adjust therapies, new markers are needed. Systemic inflammatory response (SIR) markers such as LMR, NLR, and PLR have proven to be highly prognostic in many malignancies, including CRC; however, their roles in locally advanced rectal cancer (LARC) are conflicting and lack proper validation. Sixty well-selected patients with LARC treated at the Maria Sklodowska-Curie National Research Institute of Oncology in Warsaw, Poland, between August 2017 and December 2020 were prospectively enrolled in this study. The reproducibility of the pre-treatment levels of the SIR markers, their correlations with clinicopathological characteristics, and their prognostic value were evaluated. There was a significant positive correlation between LMR and cancer-related inflammatory infiltrate (r = 0.38, p = 0.044) and PD-L1 expression in tumor cells, lymphocytes, and macrophages (combined positive score (CPS)) (r = 0.45, p = 0.016). The PLR level was correlated with nodal involvement (p = 0.033). The SIR markers proved to be only moderately reproducible and had no significant prognostic value. In conclusion, the LMR was associated with local cancer-related inflammation and PD-L1 expression in tumor microenvironments. The validity of SIR indices as biomarkers in LARC requires further investigation.

Abstract
Our study aims to investigate whether preoperative red blood cell distribution width (RDW) has a prognostic value for patients after gastric cancer (GC) surgery. We searched articles in 3 databases including PubMed, Embase, and the Cochrane Library on May 16th, 2022. The prognostic indicators included overall survival (OS) and disease-free survival (DFS). RevMan 5.3 (The Cochrane Collaboration, London, United Kingdom) and Stata V16.0 were used for statistical analysis. The Risk Of Bias In Non-randomized Studies-of Interventions tool was used to assess risk of bias of the included studies. Ten articles involving 2740 patients were included. RDW was a prognostic factor for OS (hazard ratio = 1.81, 95% confidence interval [CI] = 1.38-2.37, P < .01) and DFS (hazard ratio = 1.99, I2 = 26%, 95% CI = 1.53-2.58, P < .01) for GC patients. Meanwhile, there were some differences between the high RDW group and the low RDW group. We found more patients older than 60 years old (OR = 2.58, 95% CI = 1.08-6.13, P = .03), larger tumor diameter (OR = 1.95, 95% CI = 1.33-2.85, P < .01) and later T stage (OR = 1.91, 95% CI = 1.07-3.42, P = .03) in the high RDW group than the low RDW group. No statistic difference was found in gender, N stage, tumor node metastasis stage, vascular invasion, differentiation, and adjuvant therapy between the 2 groups (P > .05). RDW was an independent prognostic factor for both OS and DFS of GC patients. High RDW level were strongly associated with poor survival.

Abstract
BACKGROUND Inflammation plays an important role in tumor growth. Novel serum blood biomarkers, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR), have been proposed as useful prognostic indexes in cancer patients. However, their role in rectal cancer is controversial. METHODS A comprehensive literature review was conducted including MEDLINE/Pubmed, EMBASE, SCOPUS, and the Cochrane Database of Systematic Reviews through May 2022. The systematic review and meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Quality was appraised with the Methodological Index for Non-Randomized Studies (MINORS) tool. Aim of the study was to summarize available literature on PLR, NLR, and LMR in patients with rectal cancer undergoing resection. RESULTS Forty-seven observational studies (14,205 patients) were included; there were 42 retrospective and 5 prospective cohort studies with an average MINORS score of 14.6 (range: 12-18). Worse overall survival was associated with high NLR (HR 1.81; 95%CI 1.52-2.15; p < 0.001), high PLR (HR 1.24; 95%CI 1.06-1.46; p = 0.009), and low LMR (HR 0.67; 95%CI 0.49-0.91; p = 0.01). High NLR and low LMR were also associated with disease-free-survival (HR 1.68; 95%CI 1.35-2.08; p < 0.001 and HR 0.71; 95%CI 0.58-0.87; p < 0.001, respectively). CONCLUSIONS NLR, PLR, and LMR are independent clinical predictors for overall survival in patients with rectal cancer treated with curative surgery. NLR and LMR are also good predictors for disease free survival. These biomarkers, which are readily available, appear optimal prognostic indexes and may help clinicians predict the prognosis of rectal cancer and develop individualized treatment strategies.

Abstract
Many thoracic surgery procedures are now performed with video-assisted thoracoscopic surgery (VATS). Postoperative pain is a common condition in patients undergoing VATS. In this study, we aimed to investigate whether neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) are effective in evaluating postoperative pain in patients undergoing VATS.This prospective observational study was performed between March 2021 and September 2021 at a tertiary thoracic surgery center. The study included patients who had undergone elective VATS. Preoperative and postoperative NLR, PLR, LMR, hemogram values and postoperative visual analog scale (VAS) were recorded.A total of 105 patients were analyzed. A positive correlation was observed between postoperative monocyte, neutrophils and VAS resting and VAS cough levels in the early postoperative period. No significant correlation was found between preoperative and postoperative NLR, PLR, and LMR values and VAS rest and VAS cough values. When compared to the preoperative period, a negative correlation was found between the change in the postoperative LMR value and the VAS rest and VAS cough values in the early postoperative period.When compared to the preoperative period, the change in postoperative neutrophil, postoperative monocytes, and postoperative LMR values in patients undergoing VATS in thoracic surgery can be used as a guide in the objective evaluation of postoperative acute pain. It is the belief of the researchers that comprehensive new studies on this subject will contribute significantly to the determination of objective criteria in postoperative pain evaluation.

Abstract
Introduction Pretreatment inflammatory markers were applied to predict the prognosis of colorectal cancer. However, the role of these markers in predicting survival in patients with synchronous colorectal liver metastasis (CLM) is rarely reported. Notably, lymphocyte-to-monocyte ratio (LMR) was mainly reported in hematologic malignancies and is worth to be further explored to predict the survival of synchronous CLM. Methods Totally, 196 patients who were diagnosed with synchronous CLM were enrolled. Their clinical and laboratory data before treatment were collected, retrospectively. Univariate and multivariate analyses were performed to analyze the inflammatory biomarkers. Results LMR (P = .002) and lactate dehydrogenase (LDH) (P = .017) were significantly related to the progression-free survival (PFS). More factors such as neutrophil-to-lymphocyte ratio (NLR) (P = .011), carbohydrate antigen 19-9 (CA19-9) (P = .001), number of metastatic foci (P = .006), and adjuvant chemotherapy (P = .027) were correlated with overall survival (OS). In multivariate analysis, LMR remained statistically associated with PFS (P = .003). Regarding OS, LMR (P = .016) and LDH (P = .013) were significantly independent predictive factors. Conclusions The higher LMR and lower LDH were strongly correlated with better survival in synchronous CLM patients. In addition, the result also indicated that enhanced LMR was related to better PFS. The LMR and LDH can be used to predict prognosis of the synchronous CLM.

Abstract
BACKGROUND The low lymphocyte-to-monocyte ratio and high platelet-to-lymphocyte ratio have been reported to be poor prognostic indicators in various solid tumors, but the prognostic significance in rectal cancer remains controversial. OBJECTIVES We sought to determine the prognostic value of the lymphocyte-to-monocyte ratio and the platelet-to-lymphocyte ratio following curative-intent surgery for rectal cancer. DATA SOURCES Following PRISMA guidelines (PROSPERO, ID: CRD42020190880), PubMed and Embase databases were searched through January 2021 including 3 other registered medical databases. STUDY SELECTION Studies evaluating the impact of pretreatment lymphocyte-to-monocyte ratio and platelet-to-lymphocyte ratio on overall or disease-free survival in patients undergoing curative rectal cancer resection were selected. MAIN OUTCOMES MEASURES The main outcome measures were overall and disease-free survival. RESULTS A total of 23 studies (6683 patients) were included; lymphocyte-to-monocyte ratio and platelet-to-lymphocyte ratio were evaluated in 14 and 16 studies. A low lymphocyte-to-monocyte ratio was associated with poorer overall survival (HR, 1.57; 95% CI, 1.29-1.90; p < 0.001) and disease-free survival (HR, 1.29; 95% CI, 1.13-1.46; p < 0.001). However, when the analysis was limited to patients treated with surgery alone or to those with stage I to III tumors, lymphocyte-to-monocyte ratio was not a predictor of overall survival and disease-free survival. The platelet-to-lymphocyte ratio did not predict for overall or disease-free survival, regardless of the treatment modality, studied population, tumor stage, or cutoff value. Finally, a low lymphocyte-to-monocyte ratio, but not a high platelet-to-lymphocyte ratio, was inversely correlated with complete pathologic response rate. LIMITATIONS The retrospective nature of most included studies was a limitation. CONCLUSIONS Pretreatment lymphocyte-to-monocyte ratio, but not platelet-to-lymphocyte ratio, correlates with tumor response to neoadjuvant chemoradiotherapy and poorer prognosis after curative-intent surgery for rectal cancer, and it potentially represents a simple and reliable biomarker that could help optimize individualized clinical decision-making in high-risk patients.

Abstract
Simple Summary Inflammation plays a critical role in the progression of colorectal cancer (CRC). Peripheral blood cell counts could reflect the extent of systemic inflammation and are readily available in clinical practice. The aim of our study was to construct a novel prognostic inflammatory index (PII) by integrating the blood cell counts associated with prognosis and to evaluate and validate the prognostic value of PII in two independent CRC cohorts. Multivariate Cox analyses in the training cohort of 4154 CRC patients indicated that high OS-PII (>4.27) and high DFS-PII (>4.47) were significantly associated with worse OS (HR: 1.330, p < 0.001) and worse DFS (HR: 1.366, p < 0.001), which has been validated in the external validation cohort of 5161 patients. Both OS-PII and DFS-PII have a stable prognostic performance at various follow-up times, and the nomograms based on OS-PII and DFS-PII achieved good accuracy in personalized survival prediction of patients with CRC. Abstract Host inflammation is a critical component of tumor progression and its status can be indicated by peripheral blood cell counts. We aimed to construct a comprehensively prognostic inflammatory index (PII) based on preoperative peripheral blood cell counts and further evaluate its prognostic value for patients with colorectal cancer (CRC). A total of 9315 patients with stage II and III CRC from training and external validation cohorts were included. The PII was constructed by integrating all the peripheral blood cell counts associated with prognosis in the training cohort. Cox analyses were performed to evaluate the association between PII and overall survival (OS) and disease-free survival (DFS). In the training cohort, multivariate Cox analyses indicated that high OS-PII (>4.27) was significantly associated with worse OS (HR: 1.330, 95% CI: 1.189–1.489, p < 0.001); and high DFS-PII (>4.47) was significantly associated with worse DFS (HR: 1.366, 95% CI: 1.206–1.548, p < 0.001). The prognostic values of both OS-PII and DFS-PII were validated in the external validation cohort. The nomograms achieved good accuracy in predicting both OS and DFS. Time-dependent ROC analyses showed that both OS-PII and DFS-PII have a stable prognostic performance at various follow-up times. The prognostic value of tumor-node-metastasis staging could be enhanced by combining it with either OS-PII or DFS-PII. We demonstrated that PIIs are independent prognostic predictors for CRC patients, and the nomograms based on PIIs can be recommended for personalized survival prediction of patients with CRC.

Abstract
Despite the description of several new prognostic markers, colorectal cancer still represents the third most frequent cause of cancer-related death. As immunotherapy is considered a therapeutic alternative in such patients, neutrophil-to-lymphocyte (NLR) and lymphocyte-to-monocyte ratio (LMR) are hypothesized to provide reliable prognostic information. A retrospective study was conducted on 1052 patients operated on during 2013-2019 in two clinical hospitals from Hungary and Romania. Inclusion criteria targeted patients over 18 years old, diagnosed with rectal cancer, with preoperatively defined NLR and LMR. The overall survival rate, along with clinical and histopathological data, was evaluated. Overall survival was significantly associated with increased NLR (p = 0.03) and decreased LMR (p = 0.04), with cut-off values of 3.11 and 3.39, respectively. The two parameters were inversely correlated (p < 0.0001). There was no statistically significant association between tumor stage and NLR or LMR (p = 0.30, p = 0.06, respectively). The total mesorectal excision was especially obtained in cases with low NLR (p = 0.0005) and high LMR (p = 0.0009) values. A significant association was also seen between preoperative chemoradiotherapy and high NLR (p = 0.0001) and low LMR (p = 0.0001). In patients with rectal cancer, the preoperative values of NLR and LMR can be used as independent prognostic parameters. An NLR value of ≥3.11 can be used to indicate the response to preoperative chemoradiotherapy, but a low chance of sphincter preservation or obtaining a complete TME. Higher values of NLR and lower values of LMR require a more attentive preoperative evaluation of the mesorectum.

Prognostic significance of dynamic changes in lymphocyte-to-monocyte ratio in patients with head and neck cancer treated with radiotherapy: results from a large cohort study. Radiother Oncol 2020; 154:76-86. [PMID: 32941957 DOI: 10.1016/j.radonc.2020.09.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 08/23/2020] [Accepted: 09/06/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND PURPOSE We sought to investigate whether dynamic changes in lymphocyte-to-monocyte ratio (LMR) occurring during the course of radiotherapy (RT) may have prognostic value in patients with head and neck cancer (HNC). MATERIALS AND METHODS We retrospectively reviewed the clinical records of patients with HNC who underwent RT at our center between 2005 and 2013. Generalized estimating equations were used to longitudinally assess changes in LMR through the course of RT. Delta-LMR was calculated as the difference between LMR measured during treatment and baseline LMR values. Freedom from metastasis (FFM) and overall survival (OS) served as the main outcome measures. RESULTS A total of 1431 patients with HNC were enrolled. After a median follow-up of 9 years, 636 (44.4%) patients died and 240 (16.8%) had distant metastases. Compared with patients with low delta-LMR at two weeks, those with high delta-LMR experienced less favorable outcomes (five-year OS: 73% versus 59%, respectively, p < 0.001; five-year FFM: 87% versus 80%, respectively, p = 0.015). Similar findings were observed for delta-LMR measured at four weeks (five-year OS: 72% versus 60%, p < 0.001; five-year FFM: 86% versus 79%, respectively, p = 0.002) and six weeks (five-year OS: 72% versus 57%, p < 0.001; five-year FFM: 87% versus 79%, respectively, p = 0.002). Multivariate analysis identified delta-LMR as an independent prognostic factor for both FFM and OS. CONCLUSION Delta-LMR is a simple and inexpensive biomarker that may be clinically useful for predicting FFM and OS in patients with HNC treated with RT.

Abstract
Background This study was designed to investigate the prognostic value of the lymphocyte to monocyte ratio (LMR) in patients with gallbladder carcinoma (GBC). Patients and Methods We retrospectively enrolled 154 consecutive GBC patients from 2005 to 2017 in this study. The LMR of preoperative blood samples was calculated by dividing the lymphocyte count by the monocyte count. A receiver operating characteristic (ROC) curve was employed to identify the optimal cut-off value of the LMR in the determination of overall survival (OS). The Kaplan–Meier method was utilized to assess OS, and the Log rank test was employed to compare survival differences. Univariate and multivariate Cox regression analyses were conducted to detect independent prognostic indicators. Results The optimal cut-off point for the LMR was 4.76 according to the ROC curve. Patients ≤60 years old with an LMR ≤4.76 experienced significantly worse OS than those with an LMR >4.76 (hazard ratio (HR): 0.399, 95% confidence interval (CI): 0.265–0.602, P<0.001); however, the prognostic value of the LMR was not determined in patients >60 years old or among the entire study cohort (both P>0.05). Significantly poorer OS was observed in patients >60 years with an LMR ≤4.21 compared to those with an LMR >4.21 (HR: 1.830, 95% CI: 1.129–2.967, P=0.014). Multivariate Cox regression analysis indicated that both the high and low LMR cut-off values were independent risk factors for OS (HR: 0.272, 95% CI: 0.105–0.704, P=0.007; HR: 0.544, 95% CI: 0.330–0.895, P=0.017). Conclusion The LMR is an independent prognostic indicator for GBC patients, the cut-off value of which is age dependent.

Abstract
BACKGROUND This meta-analysis aimed to explore the overall effect and safety of anterior laparoscopic surgery versus conventional open surgery for patients with colorectal cancer based on eligible randomized controlled trials (RCTs), especially the difference in the postoperative incidence of deep venous thrombosis (DVT). METHODS PubMed, Cochrane, and Embase were searched based on keywords to identify eligible studies before February 2018. Only RCTs were eligible. We analyzed the main outcomes using the relative risk (RR) or mean difference (MD) along with 95% confidence interval (95% CI). RESULTS In this meta-analysis, we analyzed a total of 24 studies with 4592 patients in the laparoscopic surgery group and 3865 patients in the open surgery group. The results indicated that compared with the open surgery, laparoscopic surgery significantly decreased estimated blood loss (SMD: -1.14, 95%CI: -1.70 to -0.57), hospital stay (SMD: -1.12, 95%CI: -1.76 to -0.47), postoperative mortality (RR: 0.60, 95%CI: 0.41-0.86) and postoperative complication (RR: 0.83, 95%CI: 0.72-0.95). However, the operative time (WMD: 40.46, 95%CI: 35.94-44.9) was statistically higher in the laparoscopic surgery group than the open surgery group, and there was no significant difference in the incidence of DVT between the 2 groups (RR: 0.96, 95%CI: 0.46-2.02). CONCLUSION Laparoscopic surgery is superior to open surgery for patients with colorectal cancer. But the 2 surgeries showed no significant difference in the incidence of DVT.

Abstract
Background There is increasing evidence that inflammation-based biomarkers are associated with tumor microenvironment which plays important roles in cancer progression. A high lymphocyte-to-monocyte ratio (LMR), has been suggested to indicate favorable prognoses in various epithelial cancers. We performed a meta-analysis to quantify the prognostic value of LMR in advanced-stage epithelial cancers undergoing various treatment. Methods We searched PubMed, EMBASE, Web of science and Cochrane Library up to July 2018 for relevant studies. We included studies assessing the prognostic impact of pretreatment LMR on clinical outcomes in patients with advanced-stage epithelial cancers. The primary outcome was overall survival (OS) and the secondary outcome was progression free survival (PFS). The summary hazard ratio (HR) and 95% confidence interval (CI) were calculated. Results A total of 8984 patients from 35 studies were included. A high pretreatment LMR was associated with favorable OS (HR = 0.578, 95% CI 0.522–0.641, P < 0.001) and PFS (HR = 0.598, 95% CI 0.465–0.768, P < 0.001). The effect of LMR on OS was observed among various tumor types. A higher pretreatment LMR was associated with improved OS in chemotherapy (n = 10, HR = 0.592, 95% CI 0.518–0.676, P < 0.001), surgery (n = 10, HR = 0.683, 95% CI 0.579–0.807, P < 0.001) and combined therapy (n = 11, HR = 0.507, 95% CI 0.442–0.582, P < 0.001) in the subgroup analysis by different therapeutic strategies. The cut-off value for LMR was 3.0 (range = 2.35–5.46). Subgroup analysis according to the cut-off value showed a significant prognostic value of LMR on OS and PFS in both subgroups. Conclusions A high pretreatment LMR is associated with favorable clinical outcomes in advanced-stage epithelial cancers undergoing different therapeutic strategies. LMR could be used to improve clinical decision-making regarding treatment in advanced epithelial cancers.

Abstract
BACKGROUND Advances in treatment of rectal cancer have improved survival, but there is variability in response to therapy. Recent data suggest the utility of the lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) in predicting survival. Our aim was to examine these ratios in rectal cancer patients and determine whether any association exists with overall survival (OS). METHODS Using prospectively maintained institutional data, a query was completed for clinical stage II-III rectal adenocarcinoma patients treated from 2002 to 2016. We included patients who had a complete blood count collected before neoadjuvant chemoradiation (pre-CRT) and again before surgery (post-CRT). The LMR, NLR, and PLR were calculated for the pre-CRT and post-CRT time points. Potential cutpoints associated with OS differences were determined using maximally selected rank statistics. Survival curves were compared using log-rank tests and were adjusted for age and stage using Cox regression. RESULTS A total of 146 patients were included. Cutpoints were significantly associated with OS for pre-CRT ratios but not for post-CRT ratios. Within the pretreatment group, a "low" (<2.86) LMR was associated with decreased OS (log-rank P = 0.004). In the same group, a "high" (>4.47) NLR and "high" PLR (>203.6) were associated with decreased OS (log-rank P < 0.001). With covariate adjustment for age, and separately for final pathologic stage, the associations between OS and LMR, NLR, and PLR each retained statistical significance. CONCLUSIONS If obtained before the start of neoadjuvant chemoradiation, LMR, NLR, and PLR values are accurate predictors of 5-y OS in patients with locally advanced rectal adenocarcinoma.

Abstract
PURPOSE The lymphocyte to monocyte ratio, an inflammation-based score, has been used to predict the biological behavior of malignant tumors. However, the relationship between the lymphocyte to monocyte ratio and clinical outcomes in patients with colorectal cancer remains controversial. We conducted a meta-analysis to identify the association between the lymphocyte to monocyte ratio and the prognosis of patients with colorectal cancer. METHODS Data were retrieved from PubMed, Embase, and Web of science, the hazard ratio and odds ratios with 95% confidence intervals were used to assess the prognostic value of the lymphocyte to monocyte ratio. Outcomes of interest included prognosis, such as overall survival, disease-free survival, and cancer-specific survival in patients with colorectal cancer. RESULTS fifteen retrospective, observational, cohort studies involving 11,783 patients were identified. A high lymphocyte to monocyte ratio (LMR) was a significant predictor of better overall survival (hazard ratio = 0.57, 95% confidence interval: 0.52-0.62, P < 0.001), disease-free survival (hazard ratio = 0.77, 95% confidence interval: 0.70-0.84, P < 0.001), and cancer-specific survival (hazard ratio = 0.55, 95% confidence interval: 0.32-0.95, P = 0.031). Increased LMR is also significantly associated with the tumor invasion depth (OR: 0.77, 95% CI: 0.61-0.97) and tumor size (OR: 0.74, 95% CI: 0.61-0.89). CONCLUSIONS Our study indicated that a high lymphocyte to monocyte ratio might be a useful marker for colorectal cancer prognosis. As most of these findings were from retrospective studies, further studies are needed to verify the significance of the lymphocyte to monocyte ratio in clinical practice.

Abstract
AIM To compare the short-term and long-term outcomes of laparoscopic versus open surgery for low rectal cancer. METHODS Patients with low rectal cancer who underwent laparoscopic or open surgery at our department from January 2009 to December 2013 were enrolled in this retrospective study. The primary end points were 3-year local recurrence and overall and disease-free survival (DFS) rates. Secondary end points were intraoperative and postoperative outcomes. RESULTS Laparoscopic group had longer operative time (165.0 versus 140.0, P < .001), less blood loss (20.0 versus 40.0, P < .001), shorter length of incision (5.0 versus 18.0, P < .001), and more lymph node harvested (11.0 versus 9.0, P = .002). However, time to first flatus (P = .941), postoperative hospital stay (P = .095), postoperative complications (P = .155), and 30-day mortality (P = .683) was similar between two groups. With the median follow-up period of 65 months, the 3-year local recurrence rate was 4.3% in laparoscopic group and 7.5% in open group (P = .077); the 3-year overall and DFS rates were similar in two groups (85.9% versus 88.8%, P = .229 and 76.9% versus 79.2%, P = .448, respectively); and the overall and DFS curves were comparable between two groups (hazard ratio [HR] = 0.858, 95% confidence intervals [CI] 0.709-1.037, P = .112 and HR = 1.076, 95% CI 0.834-1.389, P = .275, respectively). CONCLUSIONS Laparoscopic surgery is safe and has equivalent long-term oncologic outcomes for low rectal cancer when compared to open surgery. Furthermore, large-scale, prospective randomized clinical trials are needed to confirm the present findings.

Abstract
Several studies have reported that elevated red blood cell distribution width (RDW) was associated with the poor prognosis of different kinds of cancers. The aim of this study was to investigate the prognostic role of RDW in patients undergoing resection for nonmetastatic rectal cancer.We retrospectively reviewed a database of 625 consecutive patients who underwent curative resection for nonmetastatic rectal cancer at our institution from January 2009 to December 2014. The cutoff value of RDW was calculated by receiver-operating characteristic curve.The results demonstrated that patients in high RDW-cv group had a lower overall survival (OS) (P = .018) and disease-free survival (P = .004). We also observed that patients in high RDW-sd group were associated with significantly lower OS (P = .033), whereas the disease-free survival (DFS) was not significantly different (P = .179).In multivariate analysis, we found elevated RDW-cv was associated poor DFS (hazard ratio [HR] = 1.56, P = .010) and RDW-sd can predict a worse OS (HR = 1.70, P = .009).We confirmed that elevated RDW can be an independently prognostic factor in patients undergoing resection for nonmetastatic rectal cancer. So more intervention or surveillance might be paid to the patients with nonmetastatic rectal cancer and elevated RDW values in the future.

Abstract
Research indicates that cancer-triggered inflammation plays a pivotal role in carcinogenesis. Here, we aimed to evaluate the correlation of lymphocyte-to-monocyte ratio (LMR) before neoadjuvant chemoradiotherapy (CRT) with clinical outcomes in patients with locally advanced rectal cancer (LARC). We retrospectively enrolled 317 consecutive patients with LARC between 2004 and 2013. The optimal cutoff values of LMR were determined using receiver operating curve analysis. Overall survival (OS) and disease-free survival related to the LMR were analyzed using the log-rank test and multivariate Cox regression methods. We found that a low LMR (≤4.91) was prominently correlated with worse prognostic features and a shorter 3-year survival rate of LARC. Moreover, multivariate Cox analysis revealed that elevated LMR was an independent factor for better OS (hazard ratio 0.538, 95% confidence interval 0.292–0.991, P=0.047). In addition, univariate logistic regression analysis showed that the LMR was not associated with tumor pathologic regression. In conclusion, LMR is identified as a valuable prognostic marker for predicting the OS of LARC patients receiving CRT.

LMR predicts outcome in patients after preoperative chemoradiotherapy for stage II-III rectal cancer. J Surg Res 2017; 222:122-131. [PMID: 29273363 DOI: 10.1016/j.jss.2017.09.053] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2017] [Revised: 08/09/2017] [Accepted: 09/29/2017] [Indexed: 12/13/2022]
Abstract
BACKGROUND Recently, lymphocyte-to-monocyte ratio (LMR) has attracted attention as a new marker of the chronic systemic inflammatory response and has been associated with patient prognosis in those who underwent chemoradiotherapy (CRT) for several solid cancers. This study aimed to evaluate the association between LMR and the prognosis of patients with rectal cancer. METHODS A total of 183 stage II-III rectal cancer patients who underwent preoperative CRT followed by surgical R0 resection were retrospectively reviewed. The LMR was calculated from pre- and post-CRT blood samples. To determine the optimal cutoff value for pre- and post-CRT LMR for predicting relapse-free survival (RFS) and overall survival (OS), a receiver operator characteristic curve was used. Cox's proportional hazard models were applied to identify risk factors for recurrence and overall mortality. RESULTS Low LMR was observed in 54 patients (pre-CRT <4.0) and 29 patients (post-CRT <1.5). Although pre-CRT LMR correlated with tumor size and ypT stage, post-CRT LMR showed no correlation to any pathologic features. Median follow-up term was 66.3 months; the 5-year RFS and OS of all patients were 72.5% and 88.7%, respectively. We found that a low pre-CRT LMR was an independent risk factor for OS (hazard ratio, 2.83; 95% confidence interval 1.03-8.13; P = 0.043). CONCLUSIONS In rectal cancer patients who have undergone preoperative CRT, a low pre-CRT LMR is a poor prognostic factor for OS.

Abstract
AIM This meta-analysis aims to compare hand-assisted laparoscopic surgery (HALS) with conventional laparoscopic surgery (LAS) for colorectal cancer (CRC) in terms of intraoperative, postoperative, and survival outcomes. MATERIALS AND METHODS A systematic literature search with no limits was performed in PubMed, Embase, and Medline. The last search was performed on March 31, 2017. The outcomes of interests included intraoperative outcomes (operative time, blood loss, length of incision, transfusion, conversion, and lymph nodes harvested), postoperative outcomes (length of hospital stay, time to first flatus, time to first bowel movement, postoperative complications, mortality, reoperation, ileus, anastomotic leakage, postoperative bleeding, wound infection, intra-abdominal abscess, urinary complication, cardiopulmonary complication, and readmission), and 5-year survival outcomes. RESULTS Nine articles published between 2007 and 2016 with a total of 1307 patients were enrolled in this meta-analysis. HALS was associated with longer length of incision. No differences were found for operative time, blood loss, transfusion, conversion, lymph nodes harvested, length of hospital stay, time to first flatus, time to first bowel movement, postoperative complications, mortality, reoperation, ileus, anastomotic leakage, postoperative bleeding, wound infection, intra-abdominal abscess, urinary complication, cardiopulmonary complication, readmission, or 5-year survival outcomes. CONCLUSION Our meta-analysis demonstrated that HALS is similar to LAS for CRC surgery in terms of intraoperative, postoperative, and survival outcomes except for the longer length of incision.

Abstract
AIM This meta-analysis aims to compare hand-assisted laparoscopic surgery (HALS) and conventional open surgery (OS) for colorectal cancer (CRC) in terms of intraoperative and postoperative outcomes, and to explore the safety, feasibility of HALS for CRC surgery. METHODS A systematic literature search with no limits was performed in PubMed, Embase, and Medline. The last search was performed on April 23, 2017. The outcomes of interests included intraoperative outcomes (operative time, blood loss, length of incision, transfusion, and lymph nodes harvested), postoperative outcomes (length of hospital stay, length of postoperative hospital stay, time to first flatus, time to first liquid diet, time to first soft diet, time to first bowel movement, postoperative complications, reoperation, ileus, anastomotic leakage, wound infection, urinary complication, pulmonary infection, and mortality). RESULTS Fifteen articles published between 2007 and 2017 with a total of 1962 patients with CRC were included in our meta-analysis. HALS was associated with longer operative time, less blood loss, smaller length of incision, shorter hospital days and postoperative hospital days, less time to first flatus, less wound infection, and less postoperative complications. There was no difference in blood transfusion, lymph node harvested, time to first liquid or soft diet, time to first bowel movement, reoperation, ileus, anastomotic leakage, pulmonary infection, urinary complications, or mortality. CONCLUSIONS Our meta-analysis suggests that HALS in CRC surgery improves cosmesis and results in better postoperative recovery outcomes by reducing postoperative complications and hospital days. Furthermore, a large randomized control study is warranted to compare the short-term and long-term outcomes of those 2 techniques for CRC treatment.
