| 1 | Predictive significance of cancer related-inflammatory markers in locally advanced rectal cancer显示文摘BACKGROUND Locally advanced rectal cancer is treated using neoadjuvant chemoradiation(nCRT),followed by total mesorectal excision(TME).Tumor regression and pathological post-treatment stage are prognostic for oncological outcomes.There is a significant correlation between markers representing cancer-related inflammation,including high neutrophil-to-lymphocyte ratio(NLR),monocyteto-lymphocyte ratio(MLR),and platelet-to-lymphocyte(MLR)and unfavorable oncological outcomes.However,the predictive role of these markers on the effect of chemoradiation is unknown.AIM To evaluate the predictive roles of NLR,MLR,and PLR in patients with locally advanced rectal cancer receiving neoadjuvant chemoradiation.METHODS Patients(n=111)with locally advanced rectal cancer who underwent nCRT followed by TME at the Minimally Invasive Surgery Unit,Siriraj Hospital between 2012 and 2018 were retrospectively analyzed.The associations between post-treatment pathological stages,neoadjuvant rectal(NAR)score and the pretreatment ratios of markers of inflammation(NLR,MLR,and PLR)were analyzed.RESULTS Clinical stages determined using computed tomography,magnetic resonance imaging,or both were T4(n=16),T3(n=94),and T2(n=1).The NAR scores were categorized as high(score>16)in 23.4%,intermediate(score 8-16)in 41.4%,and low(score<8)in 35.2%.The mean values of the NLR,PLR,and MLR correlated with pathological tumor staging(ypT)and the NAR score.The values of NLR,PLR and MLR were higher in patients with advanced pathological stage and high NAR scores,but not statistically significant.CONCLUSION In patients with locally advanced rectal cancer,pretreatment NLR,MLR and PLR are higher in those with advanced pathological stage but the differences are not significantly different. | Kitinat Timudom Thawatchai Akaraviputh Vitoon Chinswangwatanakul Ananya Pongpaibul Pornpim Korpraphong Janjira Petsuksiri Suthinee Ithimakin Atthaphorn Trakarnsanga | 2020 | World Journal of Gastrointestinal Surgery2020，12，9： | 3 |
