Abstract
BACKGROUND We previously found that autoantibodies against a panel of six tumor-associated antigens (p53, NY-ESO-1, MMP-7, Hsp70, PRDX6 and Bmi-1) may aid in early detection of esophageal squamous cell carcinoma. Here we aimed to evaluate the diagnostic value of this autoantibody panel in esophagogastric junction adenocarcinoma (EJA) patients. METHODS Serum autoantibody levels were measured by enzyme-linked immunosorbent assay in a training cohort and a validation cohort. We used receiver-operating characteristics (ROC) to calculate diagnostic accuracy. RESULTS We recruited 169 normal controls and 122 EJA patients to the training cohort, and 80 normal controls and 70 EJA patients to the validation cohort. Detection of the autoantibody panel demonstrated an area under the curve (AUC) of 0.818, sensitivity 59.0% and specificity 90.5% in training cohort, and AUC 0.815, sensitivity 61.4% and specificity 90.0% in validation cohort in the diagnosis of EJA. Measurement of the autoantibody panel could distinguish early stage EJA patients from normal controls (AUC 0.786 and 0.786, sensitivity 50.0% and 56.0%, and specificity 90.5% and 90.0%, for training and validation cohorts, respectively). Moreover, a restricted panel consisting of autoantibodies against p53, NY-ESO-1 and Bmi-1 exhibited similar diagnostic performance for EJA (AUC 0.814 and 0.823, sensitivity 53.5% and 60.0%, and specificity 90.5% and 93.7%, for training and validation cohorts, respectively) and early stage EJA (AUC 0.744 and 0.773, sensitivity 55.6% and 52.0%, and specificity 90.5% and 93.7%, for training and validation cohorts, respectively). CONCLUSIONS Autoantibodies against an optimized TAA panel as serum biomarkers appear to help identify the present of early stage EJA.

Lymphopenia in Esophageal Squamous Cell Carcinoma: Relationship to Malnutrition, Various Disease Parameters, and Response to Concurrent Chemoradiotherapy. Oncologist 2019; 24:e677-e686. [PMID: 31040254 PMCID: PMC6693723 DOI: 10.1634/theoncologist.2018-0723] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2018] [Revised: 03/18/2019] [Accepted: 04/02/2019] [Indexed: 12/16/2022] Open
Abstract
Management of esophageal squamous cell carcinoma remains challenging, because detection often occurs at advanced stages and because of the high incidence of lymph node metastasis. This article focuses on whether lymphopenia is associated with response and tumor progression in patients with advanced esophageal squamous cell carcinoma who received concurrent chemotherapy. Background. Lymphopenia occurs commonly in esophageal squamous cell carcinoma (ESCC) and may influence treatment outcomes. We aimed to examine its association with treatment response and tumor progression in patients with locally advanced ESCC treated with concurrent chemoradiotherapy (CCRT). Materials and Methods. A total of 286 patients with stage II–IVa ESCC treated with CCRT between 2015 and 2017 were analyzed. Total lymphocyte counts were assessed at baseline, weekly, and 4 weeks after CCRT. Pretreatment lymphopenia was defined as total lymphocyte count <1,000 cells per mm3 at diagnosis, and treatment‐related lymphopenia was defined as total lymphocyte count <200 cells per mm3 with 6 weeks after starting CCRT. Univariate and multivariate logistic regression methods were used to analyze factors associated treatment‐related lymphopenia and treatment response. Results. Lymphopenia was observed in 44 patients (15.4%) at initial diagnosis. Pretreatment lymphopenia was significantly associated with greater tumor length, worse T status, body mass index ≤18.5 kg/m2, and weight loss ≥3 kg in the previous 3 months. Six weeks after starting CCRT, 89 patients (31%) developed treatment‐related lymphopenia. Tumor progression and cancer‐related death were more frequently observed in treatment‐related lymphopenia group than those without (76.4% vs. 52.8% and 58.4% vs. 39.6%). A complete response (CR) was achieved in 62 patients (21.7%). In multivariate analysis, treatment‐related lymphopenia was significantly associated with lack of clinical CR, and older age, lower tumor location, greater tumor length, and larger planning target volume were independent predictors of treatment‐related lymphopenia. Conclusion. Treatment‐related lymphopenia during CCRT is an independent predictor for poor treatment response in ESCC. Implications for Practice. A total of 286 patients with locally advanced esophageal squamous cell carcinoma were treated with concurrent chemoradiotherapy (CCRT), and treatment‐related lymphopenia occurred in 31% of patients within 6 weeks from the start of CCRT. Treatment‐related lymphopenia was significantly associated with lack of treatment response, and older age, lower tumor location, greater tumor length, and larger planning target volume were independent predictors of treatment‐related lymphopenia. Lymphocyte count is an inexpensive biomarker that may be easily used by clinicians to identify patients who are most likely to benefit from CCRT.

Abstract
INTRODUCTION Chemoradiotherapy and surgery are the basis of the potentially curative treatment for esophageal cancer. Approximately 1 in 5 patients, however, do not benefit from this intensive treatment due to early treatment failure. The aim of this study was to evaluate levels of carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 at diagnosis, in relation to survival and early treatment failure (disease recurrence or death within 1 year after surgery). METHODS Patients with esophageal adenocarcinoma scheduled for chemoradiotherapy followed by surgery between 1998 and 2014 were selected from a retrospectively collected database if both CEA and CA19-9 levels were measured before the start of treatment. RESULTS Pretreatment CEA and CA19-9 levels were known in 102 patients. Median overall survival differed (P<0.001) between patients with normal levels of both CEA and CA19-9 (n=59; 51 mo), patients with elevated CEA only (n=13; 43 mo), patients with elevated CA19-9 only (n=19; 24 mo), and those with elevated levels of both CEA and CA19-9 (n=11; 11 mo). Elevation of both CEA and CA19-9 was associated with early treatment failure (odds ratio: 10.4; 95% confidence interval: 2.4-45.5, P=0.002). Median time to tumor recurrence was 34 months in patients with normal CEA and CA19-9 levels, and 7 months in those with elevated levels of both (P=0.003). CONCLUSIONS Pretreatment elevated CEA and CA19-9 levels were significantly associated with early treatment failure and decreased overall survival in this esophageal adenocarcinoma patient cohort treated with curative intent. Until prospective validation, CEA and CA19-9 might play a role in identifying high-risk patients before the start of intensive locoregional therapy.

Abstract
Previous research showed that the 4 genes of matrix metallopeptidase 9 (MMP9), cyto-keratin 20 (CK20), cyto-keratin 19 (CK19) and urokinase type plasminogen activator (uPA) are detectable in the peripheral blood. All the 4 genes are related to tumor invasion and metastasis. However, whether their expression is associated with clinicopathologic factors and the prognosis of patients with esophageal squamous cell carcinoma (ESCC) is still confused. Expression levels of MMP9, CK20, CK19, and uPA were evaluated by quantificational real-time polymerase chain reaction (qRT-PCR) in peripheral blood of 205 ESCC patients who received radical resection. The cut-off value was 1000 copy numbers. Their impacts on clinicopathologic factors and survival were investigated. The uPA expression positively correlated with gender (P = .046) and tumor size (P = .046). Meanwhile, CK19 expression positively correlated with tumor size (P = .029), vascular invasion (P = .024), and CK20 expression positively correlated with tumor size (P = .035) and degrees of differentiation (P = .032). Moreover, the overexpression of MMP9 has a correlation with postoperative radiotherapy (P = .041) and chemotherapy (P = .012). Among the 4 genes, only uPA is a prognostic indicator for disease-free survival and overall survival both in univariate analysis and multivariate analysis (P = .015). This study suggests that circulating uPA mRNA in peripheral blood can serve as a potential unfavorable prognosis biomarker in ESCC. Further perspective, multi-center and large-scale study is still needed.

Abstract
NLR/Alb (neutrophil lymphocyte ratio/albumin ratio), is a prognostic index for esophageal cancer has been confirmed. Prealbumin (PA) is more sensitive to malnutrition than albumin. A new prognostic index, named neutrophil lymphocyte ratio/prealbumin ratio (NLR/PA), for predicting the survival time in patients with esophageal squamous cell carcinoma (ESCC) was proposed.A retrospective study of 315 cases with ESCC was enrolled. The optimal cut-off values were evaluated by ROC curve (the receiver operating characteristics curve). Pearson correlation analyses were used to calculate the correlations among NLR, Alb, NLR/Alb and NLR/PA. The overall survival (OS) was calculated by Kaplan-Meier method. Cox regression analyses were performed to evaluate the prognostic factors.The optimal cut-off value was 0.01 for NLR/PA according to ROC curve. According to multivariate analyses, TNM stage, NLR, NLR/Alb, NLR/PA were prognostic factors for OS. The AUC area (the area under the receiver operating characteristics curves) of the NLR/PA was higher than the areas of NLR and NLR/Alb for all the patients. The index of NLR/ PA had a higher AUC area than that of the index of NLR or NLR/Alb for patients in stage I-II. But in stage III-IVA, the index of NLR had a higher AUC area than that of the index of NLR/PA or NLR/Alb.The index of NLR/PA is superior to the index of NLR as a prognostic indicator for patients with early stage (stage I-II) ESCC.

Abstract
Only a few cases of esophageal granulocyte-colony-stimulating-factor (G-CSF)-producing esophageal carcinosarcoma are reported, and patients with G-CSF-producing tumors are typically considered to have poor prognosis. An 89-year-old man was examined for low-grade fever and dysphagia. Chest computed tomography revealed a huge 80-mm tumor on the thoracic esophagus without direct invasion to surrounding organs. Esophagogastroduodenoscopy (EGD) showed a huge mass occupying the esophageal lumen with a superficial flat lesion. Histopathological examination revealed that the tumor was composed of bizarre giant cells and pleomorphic spindle cells with hyperchromatic nuclei. Laboratory data showed aberrant elevation of leukocyte and neutrophil counts and G-CSF levels. The tumor was finally diagnosed as a G-CSF-producing esophageal carcinosarcoma, stage II (T2N0M0, Union for International Cancer Control-TNM Classification of Malignant Tumors, 8th edition). Considering his general condition, we performed palliative radiotherapy (45 Gy/15 fr) alone after consultation with surgeons and radiation oncologists. Follow-up EGD demonstrated the disappearance of the tumor, and the histological assessment of biopsy specimens confirmed no evidence of malignancy. The leukocyte count and G-CSF levels decreased within normal range. This is a very rare case of G-CSF-producing esophageal carcinosarcoma in which a pathologically complete response was achieved using palliative radiotherapy alone.

Abstract
BACKGROUND The prognostic role of neutrophil-to-lymphocyte ratio (NLR) in esophageal cancer (EC) remains controversial. METHODS The aim of this study was to evaluate the association between NLR and oncologic outcome of EC patients through a meta-analysis. A systematic search was performed in PubMed, Web of Science and Embase for relevant studies. Meta-analysis was performed using hazard ratio (HR) and95% confidence interval (CI) as effect measures. RESULTS Finally, 33 articles with 11,039patients were included in our study. The synthesized results indicated that the elevated NLR was negatively related to overall survival (OS) (HR = 1.39, 95% CI: 1.23-1.54). When the patients were stratified according to country, pathological type, treatment strategies, sample size, and different HR estimate method, high NLR was also significantly correlated with poor OS. Similarly, elevated NLR was also associated with shorter disease-free survival (DFS), progress-free survival (PFS), relapse-free survival (RFS), and cancer-specific survival (CSS). CONCLUSION The elevated pretreatment NLR is associated with poor oncological outcomes in patients with EC. NLR may be a significant predictive biomarker in EC. Further large-cohort studies are needed to confirm these findings.

Abstract
BACKGROUND Literature has shown that aberrantly expressed microRNAs may have implications in certain cancers. A wealth of studies signal potential prognostic role of microRNA-21 in GIT cancers. This meta-analysis quantitatively determines prognostic significance of circulating microRNA-21 in esophageal squamous cell carcinoma (ESCC), pancreatic ductal adenocarcinoma (PDAC) and colorectal carcinoma (CRC). METHODS Databases of Medline, Wiley online library, Cochrane library, Taylor and Francis Online, CINAHL, Springer, Proquest, ISI Web of knowledge, ScienceDirect, and Emerald were searched using MeSH terms serum/tissue microRNA-21, prognosis, esophagus squamous cell carcinoma, pancreatic ductal adenocarcinoma, colorectal cancer. A systematic algorithm was used that selected 15 relevant studies. Meta-analysis was conducted using forest plot and a summary effect model was employed. RESULTS This meta-analysis reports significant prognostic value of miR-21 in predicting worse overall survival (OS) in ESCC, PDAC, and CRC with pooled hazard ratio (HR) of 3.49 (95% CI 2.58-4.71, p-value < 0.01). Subgroup analysis for ESCC showed a pooled HR of 3.46 (95% CI 1.88-635, p value of <0.01), worse overall survival (OS) with the pooled HR of 3.14 (95% CI 2.22-4.43, p value < 0.01) for CRC and a pooled HR of 3.77 (95% CI 1.63-8.73, p value < 0.01) for PDAC. CONCLUSION This research infers that microRNA-21 expression is a powerful prognostic tool. Expression of micro-RNA-21 is associated with poor OS and poorer disease-free survival in ESCC, PDAC and CRC.

Abstract
BACKGROUND The aim of the current study was to investigate the impact of early oral feeding (EOF) on inflammatory cytokine levels after McKeown minimally invasive esophagectomy (MIE) for cancer. METHODS This study was based on a randomized controlled trial (NCT01998230). Patients with esophageal cancer who received McKeown MIE were randomly allocated into a group that started oral feeding on postoperative day (POD) 1 (EOF group) or a second group that received nil by mouth until 7 days after operation (late oral feeding [LOF] group). We chose 86 patients, 46 patients in the EOF group and 40 patients in the LOF group, in which to analyze inflammatory cytokine levels (interleukin [IL]-6, IL-8, tumor necrosis factor-a [TNF-α], and monocyte chemotactic protein-1 [MCP-1]). RESULTS The EOF and LOF groups exhibited similar preoperative IL-6, IL-8 TNF-α, and MCP-1 levels. The levels of the four inflammatory cytokines at PODs 1 and 3 were significantly higher than the preoperative levels (all p < 0.001). At POD 5 the levels of all four inflammatory cytokines were decreased compared with those at PODs 1 and 3. At PODs 3 and 5 the levels of IL-6, IL-8, and TNF-α were significantly lower in the EOF group than in the LOF group (all p < 0.05). At POD 3 the MCP-1 levels in the EOF group were significantly lower than those in the LOF group (all p < 0.05). CONCLUSIONS Compared with conventional rehabilitation programs the EOF protocol may decrease stress response after McKeown MIE.

Abstract
Chemotherapy is among the standard treatments for esophageal cancer. The docetaxel, 5-fluorouracil, and cisplatin (DCF) protocol yields a better response rate than 5-fluorouracil plus cisplatin. However, the incidence of side effects, such as febrile neutropenia and hematologic toxicity, is also significantly high with the DCF protocol. The granulocyte colony-stimulating factor and pegfilgrastim are prophylactically administered to prevent febrile neutropenia. This retrospective study evaluated the efficacy and safety of pegfilgrastim in patients receiving DCF therapy. Of the 65 patients who were administered DCF therapy in our hospital from 2011 through 2016, 21 received pegfilgrastim 24 hours or more after the end of chemotherapy. The protocol comprised 70 mg/m2 each of docetaxel and cisplatin on day 1 and 700 mg/m2 5-fluorouracil on days 1 to 5 via intravenous injection in a 3-week cycle. The primary endpoint was the rate of grade 3-4 neutropenia and febrile neutropenia. The mean patient age was 66.4 years. The incidence of grade 3 and 4 neutropenia was 14.2 % and 11.4 %, respectively, in the pegfilgrastim group and 31.9 % and 37.8 %, respectively, in the non-pegfilgrastim group. The incidence of febrile neutropenia in the pegfilgrastim group and non-pegfilgrastim group was 11.4 % and 40.3 %, respectively. Statistical analysis showed that the incidence of neutropenia and febrile neutropenia was significantly different (p<0.05) between the two groups. Pegfilgrastim prevents severe neutropenia and febrile neutropenia in patients with esophageal cancer who are treated according to the DCF protocol.

Abstract
PURPOSE The vitamin D receptor (VDR) endocrine system has emerged as an endogenous pleiotropic biological cell regulator with anti-neoplastic effects on breast, colorectal, and prostatic adenocarcinomas. We studied the association of gene expression, polymorphisms of VDR, CYP27B1, and CYP24A1 genes and serum vitamin D levels as surrogate markers of disease progression in patients with acid reflux, Barrett's esophagus (BE), or esophageal adenocarcinoma (EAC). METHODS We analyzed blood and tissue samples from patients with biopsy-confirmed BE or EAC for vitamin D levels, gene expressions, and polymorphisms in VDR (FokI [F/f], BsmI [B/b], ApaI [A/a], and TaqI [T/t]), CYP27B1 (HinfI [H/h]), and CYP24A1 (Hpy1881 [Y/y]). Percentages of homozygous dominant/recessive or heterozygous traits were assessed for each polymorphism in all patient subgroups. RESULTS Genomic Bb and FF polymorphisms were highly prevalent in EAC patients, whereas BE patients had a high prevalence of wild-type Hpy1881 (YY polymorphism). Some polymorphisms (Yy for CYP24A1, bb for VDR) were noted only in EAC patients. Yy and bb forms were both uniquely present in some EAC patients without associated Barrett's lesions, but not in patients with concomitant BE. AA and bb polymorphisms were associated with decreased response to neoadjuvant therapy. A high level of VDR and CYP24A1 mRNA expression was observed in EAC tissue of non-responders. Serum vitamin D deficiency was common in EAC patients. CONCLUSIONS Specific polymorphisms in vitamin D metabolism-related genes are associated with the likelihood of reflux-BE-EAC progression. Identifying such polymorphisms may aid in development of better surveillance and diagnostic and therapeutic protocols.

Abstract
This study was aimed at investigating the effect of growth differentiation factor 11 (GDF11) on the proliferation and apoptosis of esophageal cancer cells. Serum levels of GDF11 in esophageal cancer patients were determined with ELISA kits, and the correlation between serum GDF11 and pathological features of esophageal cancer were determined. The effect of recombinant GDF11 on the growth of esophageal cancer cells was measured by CCK6 method. In order to investigate the effect of recombinant GDF11 on the proliferation and apoptosis of esophageal cancer cells, the expression of apoptosis-promoting protein Bax and proliferative-associated protein Bcl-2 in esophageal cancer cells were determined using western blot. Moreover, GDF11 was used to treat esophageal cancer cells, and its effect on proliferation and apoptosis was determined with MTT assay and flow cytometry, respectively. The serum content of GDF11 was much less in esophageal cancer patients than in the control group. Esophageal GDF II in cancer patients was correlated with cancer differentiation: the higher the degree of differentiation, the higher the content of GDF11. GDF11 inhibits proliferation and apoptosis of esophageal cancer cells.

[PMID: 29785080 PMCID: PMC5960817 DOI: 10.3748/wjg.v24.i19.2120] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2018] [Revised: 04/03/2018] [Accepted: 04/15/2018] [Indexed: 02/06/2023] Open
Abstract
AIM To clarify the previous discrepant conclusions, we performed a meta-analysis to evaluate the prognostic value of red cell distribution width (RDW) in esophageal cancer (EC).
METHODS We searched the PubMed, EMBASE, Web of Science and Cochrane Library databases to identify clinical studies, followed by using STATA version 12.0 for statistical analysis. Studies that met the following criteria were considered eligible: (1) Studies including EC patients who underwent radical esophagectomy; (2) studies including patients with localized disease without distant metastasis; (3) studies including patients without preoperative neoadjuvant therapy; (4) studies including patients without previous antiinflammatory therapies and with available preoperative laboratory outcomes; (5) studies reporting association between the preoperative RDW and overall survival (OS)/disease-free survival (DFS)/cancer-specific survival (CSS); and (6) studies published in English.
RESULTS A total of six articles, published between 2015 and 2017, fulfilled the selection criteria in the end. Statistical analysis showed that RDW was not associated with the prognosis of EC patients, irrespective of OS/CSS [hazard ratio (HR) = 1.27, 95% confidence interval (CI): 0.97-1.57, P = 0.000] or DFS (HR = 1.42, 95%CI: 0.96-1.88, P = 0.000). Subgroup analysis indicated that elevated RDW was significantly associated with worse OS/CSS of EC patients when RDW > 13% (HR = 1.45, 95%CI: 1.13-1.76, P = 0.000), when the patient number ≤ 400 (HR = 1.45, 95%CI: 1.13-1.76, P = 0.000) and when the study type was retrospective (HR = 1.42, 95%CI : 1.16-1.69, P = 0.000).
CONCLUSION Contrary to our general understanding, this meta-analysis revealed that RDW cannot serve as an indicator of poor prognosis in patients with EC. However, it may still be a useful predictor of unfavorable prognosis using an appropriate cut-off value.

Abstract
BACKGROUND MicroRNAs (miRNAs) have been proven to be critical players in many different types of tumors including esophageal squamous cell carcinoma (ESCC). OBJECTIVE This study aimed at investigating the correlation of miR-138 expression and clinical outcome of patients with ESCC. METHODS A total of 168 serum samples and 128 fresh cancer tissues as well as their corresponding adjacent non-cancerous tissues were collected. Real-time PCR was performed to evaluate the clinical value of miR-138 in ESCC. RESULTS Our results showed that tissue and serum miR-138 levels were both significantly reduced in ESCC compared to their respective controls. Tissue miR-138 levels were highly correlated with serum miR-138 levels. Serum miR-138 differentiated patients with ESCC from healthy controls with high accuracy. In addition, reduced tissue/serum miR-138 levels were correlated with unfavorable clinicopathological parameters including T stage, lymph node metastasis and TNM stage. ESCC patients with lower tissue/serum miR-138 levels had shorter five year overall survival compared with those with higher tissue/serum miR-138 levels. Finally, downregulation of miR-138 was demonstrated to be an independent prognostic risk factor for ESCC. CONCLUSIONS In conclusion, both tissue and serum miR-138 levels are reduced in ESCC, and might be promising prognostic biomarkers for ESCC.

Abstract
Serum levels of several tumor markers were studied in 96 patients with untreated primary squamous cell carcinoma of the esophagus. Three markers specific for digestive tract malignancies - CEA, CA19.9 and CA50 - and two non organ specific indicators of malignancy - ferritin and TPA - were evaluated. Positivity rates of CAI9.9 and CA50 were very low (4.4 % and 8.6 % respectively); the markers were therefore considered ineffective in the disease. CEA, TPA and ferritin showed a fair positivity rate (27.1 %, 28.1 %, 33.7% respectively); CEA and TPA were directly related to clinical stage, CEA levels being significantly higher in stage IV than in stage III cases (p = 0.016). TPA preoperatory levels were also directly related to a lower survival probability (p = 0.004). CEA showed significantly lower levels in tumors of lower than in those of middle (p = 0.03) and upper esophagus (p = 0.004). TPA showed a similar behaviour with lower levels in tumors of lower than of middle esophagus (p = 0.03). These findings could be due to a bulky metabolism of tumor markers drained via portail vein in the liver. From our data the following conclusions may be drawn: 1) CEA and TPA may be useful in the staging of esophageal cancer as an ancillary tool to assess the extent of the disease; 2) tumor location is an important variable when evaluating blood levels of tumor markers in patients with esophageal cancer.

Abstract
BACKGROUND We determined the serum concentrations of Programmed cell death-1 (PD-1) and its ligands (PD-L1 and PD-L2) in patients with esophageal squamous cell carcinoma (ESCC). METHODS Blood samples were collected from 85 patients with histologically proved ESCC. Serum levels of PD-1, PD-L1, and PD-L2 were measured using enzyme linked immunosorbent assays. Correlations between serum PD-1, PD-L1, and PD-L2 concentration and tumor depth, number of lymph node metastases, organ metastasis status, or disease stage were assessed and five-year survival rates according to clinicopathological characteristics were calculated. RESULTS The concentration of PD-1 was not differed according to tumor progression. On the other hand, the average concentration of PD-L1 in patients with T3/T4 disease was 15.6 (12.2-18.3) pg/mL (25-75%), and this was significantly higher than that in patients with Tis/T1/T2 disease (p = 0.020). Similarly, PD-L1 levels were significantly higher in patients with positive lymph nodes than in cases with negative lymph node involvement (p = 0.006) and were higher in patients with organ metastasis (p = 0.123) and in more advanced stage (p = 0.006). Similar tendency was observed regarding PD-L2 concentrations. PD-L2 concentration was higher in T3, T4 cases (p = 0.008), in LN positive cases (p = 0.032), and in more advanced stage (p = 0.024). CONCLUSION Our data showed that a concentration of PD-L1 in peripheral blood was high in advanced cancer and high concentration of PD-L1 predicted disease progression and also poor survival in patients with ESCC.

Cryopreservation for delayed circulating tumor cell isolation is a valid strategy for prognostic association of circulating tumor cells in gastroesophageal cancer. World J Gastroenterol 2018; 24:810-818. [PMID: 29467551 PMCID: PMC5807939 DOI: 10.3748/wjg.v24.i7.810] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2017] [Revised: 12/11/2017] [Accepted: 12/20/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To demonstrate the feasibility of cryopreservation of peripheral blood mononuclear cells (PBMCs) for prognostic circulating tumor cell (CTC) detection in gastroesophageal cancer.
METHODS Using 7.5 mL blood samples collected in EDTA tubes from patients with gastroesopheagal adenocarcinoma, CTCs were isolated by epithelial cell adhesion molecule based immunomagnetic capture using the IsoFlux platform. Paired specimens taken during the same blood draw (n = 15) were used to compare number of CTCs isolated from fresh and cryopreserved PBMCs. Blood samples were processed within 24 h to recover the PBMC fraction, with PBMCs used for fresh analysis immediately processed for CTC isolation. Cryopreservation of PBMCs lasted from 2 wk to 25.2 mo (median 14.6 mo). CTCs isolated from pre-treatment cryopreserved PBMCs (n = 43) were examined for associations with clinicopathological variables and survival outcomes.
RESULTS While there was a significant trend to a decrease in CTC numbers associated with cryopreserved specimens (mean number of CTCs 34.4 vs 51.5, P = 0.04), this was predominately in samples with a total CTC count of > 50, with low CTC count samples less affected (P = 0.06). There was no significant association between the duration of cryopreservation and number of CTCs. In cryopreserved PBMCs from patient samples prior to treatment, a high CTC count (> 17) was associated with poorer overall survival (OS) (n = 43, HR = 4.4, 95%CI: 1.7-11.7, P = 0.0013). In multivariate analysis, after controlling for sex, age, stage, ECOG performance status, and primary tumor location, a high CTC count remained significantly associated with a poorer OS (HR = 3.7, 95%CI: 1.2-12.4, P = 0.03).
CONCLUSION PBMC cryopreservation for delayed CTC isolation is a valid strategy to assist with sample collection, transporting and processing.

Abstract
In patients with cancer circulating vascular endothelial growth factor (VEGF) may be tumor-derived and have prognostic significance. Activated platelets may also be a source of VEGF, releasing it in serum formation. Debate exists as to whether serum or plasma VEGF (S-VEGF, P-VEGF) is the most appropriate surrogate marker of tumor angiogenesis. As healing wounds produce VEGF that can spill over into the circulation, we aimed to investigate the potential confounding effects of cancer surgery on both perioperative S-VEGF and P-VEGF levels and to evaluate their relationship with platelet count. S-VEGF, P-VEGF and platelet counts were measured in 23 patients undergoing esophageal cancer resection. Samples were taken preoperatively and six weeks following surgery. Seven patients were also sampled on postoperative days 1, 5 and 10. VEGF was assayed using a commercial enzyme linked immunosorbent assay. S-VEGF and P-VEGF both rose after surgery (S-VEGF; day 5: 1017 [446–1224] pg/mL and day 10: 1231 [626–2046] pg/mL versus pre-op: 329 [189–599] pg/mL. P-VEGF; day 1: 55 [46–104] pg/mL and day 10: 58 [20–154] pg/mL versus pre-op: 23 [13–46] pg/mL), falling towards pre-operative levels by six weeks. Platelet count correlated with S-VEGF (rho=0.281; p<0.05, Spearman's rank) and P-VEGF (rho=0.330; p<0.01, Spearman's rank). Platelets may contribute to VEGF levels in plasma as well as in serum. The effects of surgery on S-VEGF or P-VEGF levels are mainly transient. Care must be exercised when interpreting circulating VEGF levels in the early postoperative period.

Abstract
MicroRNAs (miRNAs) are a class of small, noncoding RNAs that have been emerging as novel regulators in esophageal adenocarcinoma. Their role has been established in various aspects of esophageal adenocarcinoma including carcinogenesis, progression, treatment, and prognosis. Therefore, miRNA detection, profiling, and quantification have become extremely important for scientists and clinicians. As miRNAs are small, their detection can be challenging. There have been various methods developed to detect and/or quantify miRNAs. This chapter aims to introduce the fundamentals and methods of the most commonly used approaches including miRNA microarrays and quantitative real-time polymerase chain reaction (RT-qPCR) to detect and quantify miRNAs in esophageal adenocarcinoma.

Abstract
Because the esophagus is easily accessible with endoscopy, early diagnosis and curative treatment of esophageal cancer is possible. However, diagnosis is often delayed because symptoms are not specific during early stages of tumor development. The onset of dysphagia is associated with advanced disease, which has a survival at 5 years lower than 15%. Population screening by endoscopy is not cost-effective, but a number of alternative imaging and cell analysis technologies are under investigation. The ideal screening test should be inexpensive, well tolerated, and applicable to primary care. Over the past 10 years, significant progress has been made in endoscopic diagnosis and treatment of dysplasia (squamous and Barrett's), and early esophageal cancer using resection and ablation technologies supported by evidence from randomized controlled trials. We review the state-of-the-art technologies for early diagnosis and minimally invasive treatment, which together could reduce the burden of disease.

Abstract
Adenocarcinoma of the esophagus is a deadly disease and median survival of patients with metastatic disease is around 1 year only. There is an unmet need to personalize treatment by identifying molecular targets and respective target therapy in esophageal adenocarcinoma. There has been success in targeting the human epidermal growth factor receptor 2 (HER2) and vasoendothelial growth factor (VEGF) pathway while more failures were encountered in the clinical studies targeting epidermal growth factor (EGFR), mammalian target of rapamycin (mTOR), and mesenchymal-epithelial transition (MET). Studies using immune-checkpoint inhibitors have shown early success, and we await mature data for clinical application. In the chapter, the target therapy and novel treatment strategy will be reviewed. In the future, it is hoped that advances in translational research in targeted therapy against esophageal adenocarcinoma will bring about new progress in clinical practice.

Abstract
AIM To identify whether chitinase 3-like 1 (CHI3L1) serves as a suitable biomarker for the prognosis of esophageal squamous cell carcinoma (ESCC) and to analyze this protein’s cellular source.
METHODS An ELISA was conducted to detect the concentration of CHI3L1 in the serum of 150 ESCC patients diagnosed between January 2001 and February 2005. The prognostic relevance of CHI3L1 was evaluated by a Kaplan-Meier and Cox regression analysis. The immunohistochemistry was reanalyzed, and fluorescent staining was utilized to explore the cellular origins of CHI3L1. We stimulated monocyte-derived macrophages (MDMs) with either IL-6 or the supernatant of the ESCC cell line Eca-109 and later investigated the level of CHI3L1 by qPCR and ELISA.
RESULTS The level of serum CHI3L1 was higher in older patients (≥ 60) than in patients under the age of 60 (P = 0.001). The patients with higher levels of CHI3L1 had a significantly shorter overall survival, whereas the traditional markers, carcinoembryonic antigen and squamous cell carcinoma antigen, were less effective (P > 0.05). A multivariate Cox analysis (P = 0.001) indicated that CHI3L1 was an independent prognostic factor for ESCC patients. Peritumoral macrophages in ESCC exhibited high levels of CHI3L1. Interleukin-6 (IL-6) and the supernatant of Eca-109 containing IL-6 stimulated MDMs to secrete CHI3L1. The serum concentration of CHI3L1 in the ESCC patients showed a weak correlation with the laboratory inflammatory parameters neutrophil (NEU, P = 0.045), neutrophil/lymphocyte rate (NLR, P = 0.016), and C-reactive protein (CRP, P < 0.001).
CONCLUSION Our study first established a connection between the pretreated CHI3L1 and patients with ESCC, and the serum CHI3L1 was primarily secreted by ESCC-surrounded macrophages.

Abstract
PURPOSE The aim of this meta-analysis was to investigate preoperative plasma fibrinogen (PPF) as a prognostic marker in esophageal carcinoma (EC) by meta-analysis. METHODS Relevant studies were sought in the databases including Pubmed, Web of Science, Cochrane library, and Wanfang databases up to Oct 10th, 2017. Hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) were used as effective value, and pooled HRs were synthesized by STATA 14.0 to assess the prognostic impact of PPF on EC patients. RESULTS A total of 8 studies with 2827 patients were collected in this meta-analysis. Our results revealed that high PPF was significantly associated with poor OS (HR = 1.90, 95% CI 1.56-2.33, P = 0.000; HR = 1.76, 95% CI 1.28-2.42, P = 0.000) and poor DFS (HR = 1.91, 95% CI 1.50-2.43, P = 0.000; HR = 1.51, 95% CI 1.16-1.97, P = 0.000) in EC patients from univariate and multivariate analysis results, respectively, which suggested that EC patients with high PPF will suffer from high postoperative mortality and recurrence rate. CONCLUSION High PPF was significantly associated with poor OS and DFS in EC patients. Fibrinogen can serve as a prognostic marker and even a future targeting molecule during the treatment of EC patients.

Abstract
BACKGROUND AND PURPOSE The derived neutrophil-lymphocyte ratio (dNLR) is a validated prognostic biomarker for cancer survival but has not been extensively studied in locally-advanced oesophageal cancer treated with definitive chemoradiotherapy (dCRT). We aimed to identify the prognostic value of dNLR in patients recruited to the SCOPE1 trial. MATERIALS AND METHODS 258 patients were randomised to receive dCRT±cetuximab. Kaplan-Meier's curves and both univariable and multivariable Cox regression models were calculated for overall survival (OS), progression free survival (PFS), local PFS inside the radiation volume (LPFSi), local PFS outside the radiation volume (LPFSo), and distant PFS (DPFS). RESULTS An elevated pre-treatment dNLR≥2 was significantly associated with decreased OS in univariable (HR 1.74 [95% CI 1.29-2.35], p<0.001) and multivariable analyses (HR 1.64 [1.17-2.29], p=0.004). Median OS was 36months (95% CI 27.8-42.4) if dNLR<2 and 18.4months (95% CI 14.1-24.9) if dNLR≥2. All measures of PFS were also significantly reduced with an elevated dNLR. dNLR was prognostic for OS in cases of squamous cell carcinoma with a non-significant trend for adenocarcinoma/undifferentiated tumours. CONCLUSIONS An elevated pre-treatment dNLR may be an independent prognostic biomarker for OS and PFS in oesophageal cancer patients treated with definitive CRT. dNLR is a simple, inexpensive and readily available tool for risk-stratification and should be considered for use in future oesophageal cancer clinical trials. The SCOPE1 trial was an International Standard Randomised Controlled Trial [number 47718479].
