肥胖与癌症:一项转化科学综述
Obesity and Cancer: A Translational Science Review.
超重和肥胖与更高的癌症发病率相关,在美国每年占新发癌症诊断的 10%。减重可能通过减轻肥胖的不良影响来降低癌症风险,但可能需要减重超过 10% 才能降低癌症风险。

在本研究中,TIL 评分高、TIN 评分低且 PD-L1 阴性的食管癌(EC)患者均表现出显著更长的生存时间。
子宫内膜癌(EC)是最常见的三种妇科恶性肿瘤之一,预计其相关死亡率将会上升。本研究旨在分析所有EC患者的免疫微环境、苏木精-伊红(H&E)染色、免疫组织化学(IHC)和生化指标(中性粒细胞/淋巴细胞比值,NLR),并通过相互比较评估这些指标对预后的影响。
研究共纳入340名EC患者。采用组织芯片法制备代表性肿瘤组织蜡块并进行PD-L1免疫组化染色,同时通过H&E染色对TIL(肿瘤浸润淋巴细胞)和中性粒细胞评分。根据外周血计算NLR。统计评估所有参数对生存、复发和转移的影响。
TIL评分较高的患者无病生存期和总生存期较长;肿瘤浸润中性粒细胞(TIN)评分较高者的无病生存期和总生存期较短(p<0.001)。PD-L1阴性患者的总生存期较长(p=0.07)。就总生存期(OS)而言,确定NLR截断值为2.72(特异度38.89%,敏感度82.57%,AUC=0.65)。NLR低于2.72的患者OS为77.11个月(±0.04;95%置信区间:71.8–81.9),NLR≥2.72者OS为76.5个月(±1.3;95%置信区间:36.3–63.7)(p=0.001)。
本研究中,TIL评分较高、TIN评分较低且PD-L1阴性的EC患者生存时间显著较长。与TIL和PD-L1相比,TIN似乎是评估OS和PFS都很有价值的指标。本研究具有开创性,为未来开展更大样本研究奠定了基础,并探索在EC患者中使用不同参数预测预后和治疗效果。
A total of 340 EC patients were included in the study. PDL-1 immunohistochemical stain was applied to blocks prepared from representative tumor tissues by Tissue Microarray method. Tumor- infiltrating lymphocytes and neutrophils were also scored with Hematoxylin Eosin stain. The NLR values calculated from peripheral blood. The effects of all parameters on survival, recurrence/metastasis were statistically evaluated.
Regarding TIL Scores, patients with higher TIL scores were found to have longer disease-free survival and total survival. In patients with high TIN scores, disease-free survival and overall survival were shorter. (p < 0.001) The overall survival of patients with PDL-1 negative was found to be longer. (p: 0.07). In terms of the effect on OS, an NLR cut-off value of 2.72 was determined (specificity 38.89 %, sensitivity 82.57 %, AUC 0.65). OS was 77.11 months ( 0.04, 95 % CI: 71.8-81.9) in the patients with NLR value slower than 2.72 and 76.5 months ( 1.3, 95 % CI: 36.3-63.7) in those with NLR 2.72 (p: 0.001).
In this study, all patients of EC with high TIL scores, low TIN scores, and with PD-L1 negativity exhibited significantly longer survival times. TIN appears to be a highly valuable parameter in terms of both OS and PFS, particularly compared to TIL and PD-L1. This research represent a pioneering study for future studies involving larger samples in the context of being able to use different parameters in predicting prognosis and treatment in patients with EC.
