Systemic inflammation score in locally advanced rectal cancer patients following total mesorectal excision.

ABSTRACT: Objective:The objective of the study was to evaluate whether any association exists between systemic inflammation score (SIS) and adverse events (AEs) and survival of locally advanced rectal cancer patients treated with total mesorectal excision (TME) followed by adjuvant chemoradiotherapy. Patients and methods:All of the 109 rectal cancer patients recruited between May 2008 and June 2015 were treated with TME followed by adjuvant chemoradiotherapy. The prognostic ability of SIS for overall survival (OS) was calculated by the receiver operating characteristic (ROC) curves. Results:According to the classification of the SIS, 22 (20.2%), 59 (54.1%) and 28 (25.7%) patients were classified as a score of 2, 1 and 0, respectively. With an area under the curve (AUC) of 0.616, the SIS score of 1 was defined as the optimal cut-off value. Therefore, we divided the patients into the SIS-low group (SIS score of 1 or 0, n=87) and SIS-high group (SIS score of 2, n=22). Multivariate analysis indicated that SIS was associated with OS (HR 0.390, 95% CI 0.186-0.817, P=0.012). The 5-year OS rate in patients without adjuvant chemotherapy was lower than the patients with adjuvant chemotherapy (53.3% vs 75.8%, P=0.010). Multivariate analysis showed that adjuvant chemotherapy was associated with OS (HR 0.217, 95% CI 0.089-0.529, P=0.001). A marginal statistically significant difference was observed in terms of leukopenia during adjuvant chemoradiotherapy between the SIS-low group and the SIS-high group (P=0.05). Conclusion:These results suggest that SIS might serve as an independent biomarker for predicting AEs and prognosis in locally advanced rectal cancer treated with TME followed by adjuvant chemoradiotherapy. Strengthening treatment may be administered to locally advanced rectal cancer with high SIS score obtained before adjuvant chemoradiotherapy.

Project description:BackgroundMinimally invasive total mesorectal excision (MiTME) and transanal total mesorectal excision (TaTME) are popular trends in mid and low rectal cancer. However, there is currently no systematic comparison between MiTME and TaTME of mid and low-rectal cancer. Therefore, we systematically study the perioperative and pathological outcomes of MiTME and TaTME in mid and low rectal cancer.MethodsWe have searched the Embase, Cochrane Library, PubMed, Medline, and Web of Science for articles on MiTME (robotic or laparoscopic total mesorectal excision) and TaTME (transanal total mesorectal excision). We calculated pooled standard mean difference (SMD), relative risk (RR), and 95% confidence intervals (CIs). The protocol for this review has been registered on PROSPERO (CRD42022374141).ResultsThere are 11010 patients including 39 articles. Compared with TaTME, patients who underwent MiTME had no statistical difference in operation time (SMD -0.14; CI -0.31 to 0.33; I2=84.7%, P=0.116), estimated blood loss (SMD 0.05; CI -0.05 to 0.14; I2=48%, P=0.338), postoperative hospital stay (RR 0.08; CI -0.07 to 0.22; I2=0%, P=0.308), over complications (RR 0.98; CI 0.88 to 1.08; I2=25.4%, P=0.644), intraoperative complications (RR 0.94; CI 0.69 to 1.29; I2=31.1%, P=0.712), postoperative complications (RR 0.98; CI 0.87 to 1.11; I2=16.1%, P=0.789), anastomotic stenosis (RR 0.85; CI 0.73 to 0.98; I2=7.4%, P=0.564), wound infection (RR 1.08; CI 0.65 to 1.81; I2=1.9%, P=0.755), circumferential resection margin (RR 1.10; CI 0.91 to 1.34; I2=0%, P=0.322), distal resection margin (RR 1.49; CI 0.73 to 3.05; I2=0%, P=0.272), major low anterior resection syndrome (RR 0.93; CI 0.79 to 1.10; I2=0%, P=0.386), lymph node yield (SMD 0.06; CI -0.04 to 0.17; I2=39.6%, P=0.249), 2-year DFS rate (RR 0.99; CI 0.88 to 1.11; I2=0%, P = 0.816), 2-year OS rate (RR 1.00; CI 0.90 to 1.11; I2=0%, P = 0.969), distant metastasis rate (RR 0.47; CI 0.17 to 1.29; I2=0%, P = 0.143), and local recurrence rate (RR 1.49; CI 0.75 to 2.97; I2=0%, P = 0.250). However, patients who underwent MiTME had fewer anastomotic leak rates (SMD -0.38; CI -0.59 to -0.17; I2=19.0%, P<0.0001).ConclusionThis study comprehensively and systematically evaluated the safety and efficacy of MiTME and TaTME in the treatment of mid to low-rectal cancer through meta-analysis. There is no difference between the two except for patients with MiTME who have a lower anastomotic leakage rate, which provides some evidence-based reference for clinical practice. Of course, in the future, more scientific and rigorous conclusions need to be drawn from multi-center RCT research.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO, identifier CRD42022374141.
