BACKGROUND:Several immune-inflammatory markers are associated with cancer progression. The purpose of the present study was to clarify the influence of the preoperative C-reactive protein-to-albumin ratio (CRP/ALB ratio) on survival of patients with esophageal cancer and recurrence after curative resection. PATIENTS AND METHODS:The preoperative CRP/ALB ratio was evaluated in 122 patients who underwent radical resection for esophageal cancer from 2005 to 2018. The correlations between the CRP/ALB ratio and cancer-specific overall (OS), recurrence-free (RFS) survival and the clinicopathological status were analyzed. RESULTS:The optimal cut-off value of the CRP/ALB ratio determined using receiver operating characteristic curve analysis was 0.04. Patients were divided into two groups based on this cut-off value: the low CRP/ALB group (n=59) and the high CRP/ALB group (n=50). The OS rate at 5 years after surgery was significantly lower in the group with high CRP/ALB at 40.5% whilst it was 63.5% in the low CRP/ALB group (p=0.005). The corresponding RFS rates at 5 years after surgery were 32.5% and 48.3%, respectively, which was a statistically significant difference (p=0.007). A multivariate analysis showed that a high CRP/ALB ratio was a significant independent risk factor for poorer cancer-specific OS and RFS. CONCLUSION:The preoperative CRP/ALB ratio was a strong prognostic marker for patients with esophageal cancer. The surgical strategy, including procedure and perioperative care should be carefully planned for patients with a high CRP/ALB ratio.


背景: 几种免疫炎症标志物与癌症进展相关。本研究的目的是阐明术前 C 反应蛋白与白蛋白比值 (CRP/ALB 比值) 的影响。食管癌患者的生存和根治性切除术后复发。 患者和方法: 对 2005年至 2018年行食管癌根治术的 122 例患者进行术前 CRP/ALB 比值评估。分析 CRP/ALB 比值与肿瘤特异性总体 (OS) 、无复发生存率 (RFS) 和临床病理状态的相关性。 结果: 采用受试者工作特征曲线分析确定的 CRP/ALB 比值的最佳临界值为 0.04。根据临界值将患者分为低 CRP/ALB 组 (n = 59) 和高 CRP/ALB 组 (n = 50)。高 CRP/ALB 组术后 5 年的 OS 率显著低于 40.5%,而低 CRP/ALB 组为 63.5% (p = 0.005)。术后 5 年相应 RFS 率分别为 32.5% 和 48.3%,差异有统计学意义 (p = 0.007)。多变量分析显示,高 CRP/ALB 比值是较差癌症特异性 OS 和 RFS 的显著独立危险因素。 结论: 术前 CRP/ALB 比值是食管癌患者较强的预后指标。对于 CRP/ALB 比值较高的患者,应仔细规划手术策略,包括手术和围手术期护理。

METHODS:PURPOSE:The purpose of this study was to compare the survival and toxicities in cervical esophageal squamous cell carcinoma (CESCC) treated by concurrent chemoradiothrapy with either three-dimensional conformal radiotherapy (3D-CRT) or intensity-modulated radiotherapy (IMRT) techniques. Materials and Methods:A total of 112 consecutive CESCC patients were retrospectively reviewed. 3D-CRT and IMRT groups had been analyzed by propensity score matching method, with sex, age, Karnofsky performance status, induction chemotherapy, and tumor stage well matched. The Kaplan-Meier method and Cox proportional hazards model were used for overall survival (OS) and progression-free survival (PFS). Toxicities were compared between two groups by Fisher exact test. RESULTS:With a median follow-up time of 34.9 months, the 3-year OS (p=0.927) and PFS (p=0.859) rate was 49.6% and 45.8% in 3D-CRT group, compared with 54.4% and 42.8% in IMRT group. The rates of grade ≥ 3 esophagitis, grade ≥ 2 pneumonitis, esophageal stricture, and hemorrhage were comparable between two groups, while the rate of tracheostomy dependence was much higher in IMRT group than 3D-CRT group (14.3% vs.1.8%, p=0.032). Radiotherapy technique (hazard ratio [HR], 0.09; 95% confidence interval [CI], 0.01 to 0.79) and pretreatment hoarseness (HR, 0.12; 95% CI 0.02 to 0.70) were independently prognostic of tracheostomy dependence. CONCLUSION:No survival benefits had been observed while comparing IMRT versus 3D-CRT in CESCC patients. IMRT with fraction dose escalation and pretreatment hoarseness were considered to be associated with a higher risk for tracheostomy dependence. Radiation dose escalation beyond 60 Gy should be taken into account carefully when using IMRT with hypofractionated regimen.

METHODS::The radial force of esophageal stents may not completely change during extraction and therefore, the procedure of stent removal may cause tissue damage. The present study reports the manufacture of 2 novel detachable stents, which were designed to reduce tissue damage through their capacity to be taken or fall apart prior to removal and evaluated the supporting properties of these stents and the extent of local mucosal injury during their removal. The stents were manufactured by braiding, heat-setting, coating and connecting. The properties of the stents were evaluated by determining the following parameters: Expansion point, softening point, stent flexibility, radial compression ratio and radial force. A total of 18 rabbits with induced esophageal stricture were randomly assigned to 3 groups as follows: Detachable stent (DS) group, biodegradable stent (BS) group and control group. The stricture rate, complications, survival, degradation and stent removal were observed over 8 weeks. The stents of the DS and BS groups provided a similar supporting effect. The stricture rate, incidence of complications and survival were also similar between the 2 groups, while significant differences were noted between the DS and control groups and between the BS and control groups. In the BS group, the stents were degraded and moved to the stomach within 7 weeks (2 in 6 weeks and 3 in 7 weeks). The debris was extracted using biopsy forceps. In the DS group, all stents were easy to remove and 2 cases exhibited minor hemorrhage. In conclusion, the 2 types of novel detachable stent provided an equally efficient supporting effect in vitro and in vivo and may reduce the incidence of secondary injury during stent removal.

METHODS:BACKGROUND:Immune imbalance and inflammation have been suggested as key factors of Barrett's esophagus (BE) pathway towards adenocarcinoma. The neutrophil-lymphocyte ratio (NLR) indirectly reflects the relation between innate and adaptive immune systems and has been studied in premalignant conditions as a biomarker for cancer diagnosis. Our aim was to investigate if increasing values of NLR correlated with advancing stages of BE progression to dysplasia and neoplasia. METHODS:We retrospectively analyzed data of patients with biopsies reporting BE between 2013 and 2017 and with a complete blood count within 6 months from the endoscopy, as well as patients with esophageal adenocarcinoma (EAC). NLR was calculated as neutrophil count/lymphocyte count. Cases (n = 113) were classified as non-dysplastic BE (NDBE, n = 72), dysplastic BE (DBE, n = 11) and EAC (n = 30). RESULTS:NLR progressively increased across groups (NDBE, 1.92 ± 0.7; DBE, 2.92 ± 1.1; EAC 4.54 ± 2.9), with a significant correlation between its increasing value and the presence of dysplasia or neoplasia (r = 0.53, p  2.27 was able to diagnose EAC with 80% sensitivity and 71% specificity (area under the curve = 0.8). CONCLUSION:NLR correlates with advancing stages of BE progression, a finding that reinforces the role of immune imbalance in EAC carcinogenesis and suggests a possible use of this marker for risk stratification on surveillance strategies.
