[PMID: 34704390 PMCID: PMC8607254 DOI: 10.1002/cam4.3703] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2020] [Accepted: 10/18/2020] [Indexed: 01/10/2023] Open
Abstract
Introduction Circular RNAs (circRNAs) play critical roles in tumorigenesis, but their clinical efficacy in esophageal squamous cell carcinoma (ESCC) still retains controversial. This meta‐analysis aims at evaluating the associations between circRNA expressions and clinicopathologic features as well as the diagnostic and prognostic values of circRNAs in ESCC. Materials & Methods PubMed, EMBASE, and other online databases were systematically searched to collect studies on circRNAs and clinicopathological features, diagnostic, and/or prognostic assessments of ESCC. The quality of included studies was evaluated using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS‐2) and Newcastle‐Ottawa Scale (NOS) scales. The included studies were quantitatively weighted and merged, and diagnostic indicators, hazard ratios (HRs) and the corresponding 95% confidence intervals (CIs) were calculated. P values were merged by Fisher᾽s method. Sources of heterogeneity were traced using subgroup, sensitivity, and meta‐regression analyses. Results As a result, 12 studies were included, representing 769 ESCC patients. The meta‐analysis showed that abnormal expressions of circRNAs were associated to TNM stage as well as lymph node and distant metastases in ESCC cases. CircRNA was used to distinguish ESCC patients from healthy controls, and the merged sensitivity, specificity, and the area under the curve (AUC) of ESCC were 0.78 (95% CI: 0.74–0.81), 0.79 (95% CI: 0.75–0.83), and 0.86, respectively. The survival analysis showed that upregulated oncogenic circRNA levels in ESCC tissues was associated with the shorter overall survival (OS) of the patients (univariate analysis: HR = 2.25, 95% CI: 1.71–2.95, p = 0.000, I2 = 0.0%; multivariate analysis: HR = 2.50, 95% CI: 1.61–3.89, p = 0.000, I2 = 0.0%), while the OS of ESCC patients presenting overexpressions of tumor‐suppressive circRNAs was significantly ameliorated (HR = 0.29, 95% CI: 0.20–0.42, p = 0.000, I2 = 0.0%). The subgroup analyses based on circRNA biofunctions, sample size, and reference gene also revealed robust results. Conclusion CircRNAs can be used as promising molecular biomarkers for the early diagnosis and prognosis monitoring of ESCC.

Abstract
PURPOSE Esophageal squamous cell carcinoma (ESCC) is an extremely fatal and relatively rare gastrointestinal system malignancy. This study aimed to investigate the factors affecting survival in operated patients with ESCC. MATERIALS AND METHODS We included 110 patients (38 [34.5%] male; 72 [65.5%] female) aged ≥ 18 (median age, 54 [26-77]) years who were operated without any signs of metastases and followed up at Van Yüzüncü Yıl University Dursun Odabaşı Medical Center between 2004 and 2019. RESULTS Initially, 39 (35.5%) patients were clinical lymph node-positive and 71 (64.5%) patients were negative. Thirty-five (31.8%) patients underwent surgery after neoadjuvant chemoradiotherapy (nCRT), and 75 (%68.2) patients underwent direct surgery without nCRT. Five-year overall survival (OS) was 84.4% and 59.2% in patients who underwent surgery after nCRT and in those who underwent direct surgery, respectively. Median OS was significantly longer in patients who underwent surgery after nCRT (p = 0.003). There was a statistically significant difference in OS in patients who underwent surgery after nCRT depending on tumor response (p = 0.04). In multivariate analysis, advanced pathologic stage (p = 0.002) adversely affected survival, whereas nCRT administration (p = 0.031) positively affected OS. CONCLUSION We suggest that nCRT should be administrated before surgery, especially in locally advanced ESCCs. In addition, we believe that nCRT response can be used as a good parameter for survival. These results, however, should be supported by prospective studies.

Abstract
OBJECTIVE Squamous cell esophageal cancer (ESCC) is a highly fatal malignancy. This study aims to investigate the factors affecting survival in patients with metastatic and non-metastatic ESCC. METHODS Between 2008 and 2016, 107 patients with ESCC who were followed up in an oncology clinic were included in the analysis. Patients were grouped based on the stage of disease as clinical-stage II to IV. RESULTS Of the 107 patients, 55 (55.1%) of them were male and 52 (48.6%) of them were female. The mean age was 60.8 years. Based on the clinical-stage, 28 (26.2%) patients had stage II disease, 33 (30.8%) had stage III disease, and 46 (43.0%) had stage IV disease. Twenty-nine (27.1%) patients with the non-metastatic disease underwent surgery following neoadjuvant chemoradiotherapy (CRT), while 29 (27.1%) patients received definitive CRT. Twenty-six (56.5%) patients with metastatic disease received chemotherapy (CT). While median overall survival (mOS) could not be reached in patients who underwent surgery following neoadjuvant CRT, mOS for patients receiving definitive CRT versus patients treated with surgery alone-was 22.0 months and 24.0 months, respectively (p=0.008). In the metastatic stage, mOS was 8.0 months for the patients treated with a first-line CT and 3.0 months for patients receiving best supportive care (p<0.001). In multivariate analysis, factors predicting survival in patients with the non-metastatic disease were ECOG PS 3-4 (Hazard ratio [HR], 6.13), undergoing surgery (HR, 0.22), clinical-stage III disease (HR, 3.19), and presence of recurrence (HR, 24.12). For patients with metastatic disease, ECOG PS 3-4 (HR, 3.31), grade-III histology (HR, 3.39), liver metastasis (HR, 2.53), and receiving CT (HR, 0.15) were the factors associated with survival in multivariate analysis. CONCLUSION In our study, surgery and early clinical-stage increased survival, whereas experiencing recurrence adversely affected survival in non-metastatic ESCC. In the metastatic stage, ECOG PS 3-4, grade-3 histology and liver metastasis adversely affected survival, while receiving CT significantly improved survival.

Abstract
After curative treatment of esophageal squamous cell cancer (ESCC), patients are
at high risk for recurrence. The objective of this study was to develop an index
with a high sensitivity and specificity to predict ESCC patients’ recurrence and
prognosis. A retrospective analysis was conducted on consecutive patients with
EC who underwent esophagectomy. In total, 1417 patients were included in the
current investigation. In total, 770 patients were included in the current
study’s exploratory group. Alcohol consumption, TNM classification, number of
lymph node station metastases, and number of lymph node metastases were
significantly correlated with recurrence. Multivariate logistical regression
analysis resulted in the development of an equation for predicting recurrence
and prognosis (REEC). When using the REEC value to predict recurrence, the
cutoff value was 1.095, the area under the curve (AUC) values of the REEC were
0.68 (p < 0.001) in the Exploratory Group and 0.65
(p < 0.001) in the Validation Group, and the sensitivity
and specificity were 76.68% and 51.18%, respectively. When using the REEC value
to predict prognosis, the cutoff value was 1.215, the AUC values of the REEC
were 0.65 (p < 0.001) in the Exploratory Group and 0.64
(p < 0.001) in the Validation Group, and the sensitivity
and specificity were 73.12% and 50.67%, respectively. In the Exploratory Group,
when the REEC value was >1.095, patients had a longer median overall survival
(OS) and median disease-free survival (DFS) than those whose REEC value was <
1.095 (70.01±2.01 months versus 50.92±2.85 months and 75.66±1.35 months versus
53.68±2.81 months, respectively, p < 0.001). The differences
were confirmed to still exist in the Validation Group (48.12±1.47 vs 32.68±2.53
months and 55.61±1.32 vs 35.68±2.73 months respectively, p <
0.001).This study reported an index that can predict esophageal cancer
recurrence and prognosis, and its use can benefit patients.

Abstract
BACKGROUND Nidogen-2 (NID2), a secretory basement membrane protein, has been implicated as a potential biomarker in ovarian cancer and hepatocellular carcinoma. OBJECTIVE In this study, we aimed to investigate the utility of detecting serum NID2 levels for identification of esophageal squamous cell carcinoma (ESCC) patients and prediction of poor survival outcome. METHODS Using an in-house NID2 enzyme-linked immunosorbent assay (ELISA), serum samples from 101 ESCC patients and 50 healthy controls were screened for their NID2 levels. RESULTS The serum NID2 levels in ESCC patients (median 24.4 μg/L) are significantly higher (p= 4.3e-09) than that of the healthy controls (median 15.85 μg/L). The receiver operating characteristic (ROC) curve demonstrated an area under the curve of 0.756. At the threshold of 17.95 μg/L, the sensitivity and specificity achieved are 0.76 and 0.63, respectively. Kaplan-Meier survival analysis revealed that patients with high serum NID2 levels (⩾ 32.6 μg/L) have significantly higher risk of death (HR = 1.984, 95% CI: 1.175-3.349; log-rank p-value = 0.012) compared to those with low serum NID2 levels (< 20.0 μg/L). CONCLUSIONS In conclusion, we show that detecting the elevation of serum NID2 levels has potential diagnostic and prognostic value for ESCC patients.

Abstract
The Glasgow Prognostic Score (GPS), neutrophil/lymphocyte ratio (NLR) and prognostic nutritional index (PNI) are prognostic parameters for malignancies. Additionally, serum squamous cell carcinoma antigen (SCC-Ag) and cytokeratin 19 fragments (CYFRA 21-1) are tumor markers for squamous cell carcinoma. In the present study, the prognostic importance of these markers in patients with resectable thoracic esophageal cancer was investigated. In this retrospective study, 84 enrolled patients diagnosed with resectable clinical stage I-III thoracic esophageal squamous cell carcinomas (ESCCs) underwent thoracic esophageal resection and three-field lymph node dissection at Tottori University Hospital between January 2007 and December 2013. The correlations among preoperative patient markers (GPS, NLR, PNI, SCC-Ag and CYFRA 21-1) and the occurrence of postoperative complications and patient survival were analyzed. The operative mortality was 2.4%, and morbidity was 42.9%. Strong correlations between occurrence of postoperative complications and open thoracotomy (P=0.083) and high-serum CYFRA 21-1 (P=0.007) were observed. In 15 patients with high-serum CYFRA 21-1, postoperative complications were detected in 11 of them (73.3%); on the other hand, complications occurred in 25 of 69 (36.2%) with low-serum CYFRA 21-1. The 5-year disease-free survival rate and 5-year overall survival rate of all the patients were 52.2 and 50.8%, respectively. Among the prognostic parameters, preoperative high NLR was determined to be a poor prognostic factor, independent of the tumor stage in the multivariate analysis. These results may indicate that, in patients with preoperative high-serum CYFRA 21-1, more attention should be paid to the occurrence of postoperative complications. Therefore, in such cases, anastomosis between blood vessels of the substitute esophagus and cervical vessels would be recommended. Furthermore, in patients with high preoperative NLR, effective adjuvant chemoradiotherapy should be considered to prolong the patients' survival, even of stage I or II patients.

Abstract
The purpose of this study was to evaluate the potential of serum CYFRA21-1 and carcinoembryonic antigen (CEA) as prognostic markers in patients with undifferentiated nasopharyngeal carcinoma. Sixty-one patients who received definitive radiotherapy/chemoradiotherapy were analysed retrospectively. We investigated the association of the follow-up results with pretreatment level, post-treatment level and change of serum CYFRA21-1 and CEA, respectively. Patients with low pretreatment CYFRA21-1 had a significantly better overall survival. There were no significant associations among the remaining serum markers, and the survival and recurrence rates on multivariate analysis. The present study shows that pretreatment CYFRA21-1 level is a potential factor for predicting long-term survival.

Abstract
The purpose of this study was to investigate clinical-biological factors which could predict the sensitivity to chemoradiotherapy of esophageal squamous cell carcinoma (ESCC). One hundred eighty-one patients with stages I-IV ESCC were evaluated. The cytokeratin 19 fragment antigen 21-1 (CYFRA21-1), carcinoembryonic antigen (CEA), albumin (A) as well as hemoglobin (HB) concentration were measured before the initiation of chemoradiotherapy (CRT). The cutoff values of CYFRA21-1, CEA, and A were defined as 3.4 ng/ml, 3.3 ng/ml, 3.5 g/dl, respectively. HB was divided into three levels: <12.0, 12.0-14.0, and >14.0 g/dl. Clinical factors such as sex, age, tumor location, primary cancer length, and tumor-node-metastasis stage were also evaluated. The effective rate (complete response + partial response) of the primary tumor estimated by computed tomography was 60.71% (17 out of 28) in patients with CEA high group while 92.54% (62 out of 67) in patients with CEA low group (P = 0.000) and 62.50% (20 out of 32) in patients with CYFRA21-1 high group while 92.98% (53 out of 57) in patients with CYFRA21-1 low group (P = 0.000). HB levels before and during CRT were also associated with the effectiveness (P = 0.005, 0.033, respectively). HB levels before CRT at 12.0-14.0 g/dl were associated with the best effectiveness, followed by >14.0 and <12.0 g/dl (effective rates 88.89% vs. 83.75%, 62.07%, respectively, P = 0.005). HB levels during CRT also showed similar results (effective rates 87.80% vs. 85.41%, 70.59%, respectively, P = 0.033). Furthermore, according to numbers of the above risk factors, the sensitivity of CRT was higher in patients with zero to one risk factors than those with two to four risk factors (P = 0.023). CYFRA21-1 and CEA as well as HB and their combination may be helpful in predicting the sensitivity to CRT of ESCC. However, the results should be further confirmed in larger, more homogeneous studies.

Abstract
Esophageal squamous cell carcinoma (ESCC), the main type of esophageal cancer, is one of the most common gastrointestinal malignant cancers. Tumor markers detection are easy, economical, fast and non-invasive. Some tumor markers can be expressed before morphological changes occurred in tissues and organs; therefore, they can be used for the diagnosis of disease in the asymptomatic stage, thus making the research into tumor marker discovery even more meaningful. This paper summarizes several known tumor makers' expression detected in ESCC in recent years, and illustrates them from the aspects of genes, proteins, autoimmune antibodies, antigens and prognostic factors.

Abstract
It is reported that surveillance of serum p53 antibody (Ab) is a useful marker in detecting esophageal squamous cell carcinoma (ESCC). But there is little reported about prognostic significance of serum p53-Ab in postoperative patients with ESCC. The aim of this study is to evaluate the significance of preoperative serum p53-Ab as a marker of early recurrence after curative resection for ESCC. Enzyme-linked immunosorvent assay (ELISA) was used to analyze serum p53-Ab before treatment in 44 patients with ESCC. Carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCC-Ag) were examined by immunoradiometric assay. The patients who were strongly positive and positive in serum p53-Ab were more likely to have early recurrence after curative resection than seronegative patients. There were no significant correlations between CEA, SCC-Ag positivity and early recurrence. We found that serum p53-Ab was useful to predict a risk of early recurrence after curative surgical resection for ESCC.

Abstract
PURPOSE The clinical significance of isolated tumor cells (ITC) in blood has not been clearly established, particularly during follow-up in cancer patients. We conducted a longitudinal analysis of the relationship between ITC in blood during follow-up and clinicopathologic findings in patients with esophageal squamous cell carcinoma. EXPERIMENTAL DESIGN Blood samples obtained from 106 patients were examined by real-time RT-PCR assay targeting carcinoembryonic antigen (CEA) mRNA. Follow-up examination every 3 months after surgery included testing for CEA mRNA and tumor markers, as well as imaging. RESULTS Thirty-nine (36.8%) patients were positive for CEA mRNA expression. CEA mRNA positivity significantly correlated with tumor depth, lymph node metastasis, stage, and venous invasion. Recurrent disease was found in 34 of 106 (32.1%) cases. CEA mRNA was found in 28 (76.5%) patients experiencing relapse. Of these 28 patients, the number positive of CEA mRNA before detection by imaging, at the same time of detection by imaging, and after detection by imaging was 18 (52.9%), 8 (23.5%), and 2 (5.9%), respectively. The sensitivity, specificity, positive predictive value, and negative predictive value for CEA mRNA were higher than those for serum CEA or squamous cell carcinoma. Patients positive for CEA mRNA experienced significantly shorter disease-free interval than those with negative CEA mRNA (P < 0.001). According to multivariate analysis, CEA mRNA positivity was an independent factor for disease-free interval. CONCLUSIONS Examination of CEA mRNA in peripheral blood during follow-up is useful for early detection of occult recurrence. We believe that CEA mRNA in blood will be a new marker for recurrence in esophageal squamous cell carcinoma.

Abstract
In cancer, apoptotic processes occur both spontaneously and induced by antitumor therapies. Qualitative and quantitative changes in cancer cell death along with proliferative alterations are essential determinants in the pathogenesis and progression of malignant disease and its responsiveness to therapy. Besides detecting apoptosis by invasive means in tumor tissue, apoptotic products can be quantified in the circulation. Although circulating apoptotic products usually lack organ and tumor specificity, they contribute in the assessment of disease extent or aggressiveness. The ease of drawing blood facilitates the serial measurement of circulating apoptotic markers to monitor antitumor treatment and predict early response to therapy. This review describes the features of apoptotic and necrotic cell death along with the role the balance between the rates of cell death and cell proliferation plays in the progression of malignancy. The intracellular pathways mediating apoptosis are next summarized. The focus then shifts to the apoptotic markers found in the circulation and their diagnostic, prognostic, predictive, and management utility in cancer.

Abstract
BACKGROUND Increased preoperative serum squamous cell carcinoma antigen (SCC-Ag) concentrations have been found to be associated with advanced stage and poor prognosis in lung and cervical cancers. Because little was known about the significance of SCC-Ag concentration in patients with esophageal cancer, the aim of this study was to analyze the clinicopathologic significance of SCC-Ag in patients with esophageal SCC. PATIENTS AND METHODS. Preoperative SCC-Ag concentration was measured with enzyme-linked immunosorbent assay in 309 patients with primary esophageal SCC. All patients underwent curative radical surgery without any preoperative therapy. In 215 of 309 patients, carcinoembryonic antigen (CEA) was also measured to compare clinical significance of CEA with that of SCC-Ag. The prognostic significance for survival of SCC-Ag concentrations was studied with multivariate analysis with Cox proportional hazards model. RESULTS The SCC-Ag concentration and the positivity rate of SCC-Ag were significantly elevated in patients associated with tumor progression. Statistically significant differences in SCC-Ag concentrations and SCC-Ag positivity rates were observed depending on tumor size, tumor depth, lymph node status, and distant metastasis. Although CEA was not a prognostic factor (P =.21), a high SCC-Ag concentration was a significant prognostic factor (P <.01). Multivariate analyses indicated that T factor had the best predictive power, but SCC-Ag concentration contained additional, independent prognostic information. CONCLUSION Our findings suggest that preoperative serum SCC-Ag concentrations might provide a predictive information for tumor progression and survival in patients with esophageal SCC.

Abstract
BACKGROUND CYFRA 21-1 has been reported as a useful tumor marker for esophageal carcinoma, but little information was reported about the clinicopathologic importance of CYFRA 21-1. The aim of this study was to analyze the clinicopathologic and prognostic significance of preoperative CYFRA 21-1 in patients with esophageal squamous cell carcinoma. STUDY DESIGN The CYFRA 21-1 levels were measured before surgery by enzyme-linked immunosorbent assays in 157 patients with primary esophageal squamous cell carcinomas using 3.5 ng/mL as the upper limit of normal. All patients underwent radical surgical procedures without any preoperative therapy. The association between the clinicopathologic factors assessed and the CYFRA 21-1 level was determined. The CYFRA 21-1 values were monitored after surgery in 45 available patients. The prognostic values were determined by multivariate analysis using Cox's proportional hazards model. RESULTS Thirty-one of the 157 patients (19.7%) had high CYFRA 21-1 levels (> or =3.5 ng/mL). CYFRA 21-1 levels were significantly increased in patients with large tumors (> or =40 mm, p = 0.009), deep tumors (T2-T4, p = 0.003), and node-positive tumors (p = 0.003). CYFRA 21-1 levels significantly decreased after surgery (p < 0.001). A high CYFRA 21-1 level before surgery was an independent prognostic factor for survival (p = 0.043). CONCLUSIONS A high CYFRA 21-1 level is associated with tumor progression and poor survival in patients with esophageal squamous cell carcinoma.

Abstract
BACKGROUND The clinical significance of circulating tumor cells in the blood during surgery has not been elucidated in esophageal squamous cell carcinoma (ESCC). We evaluated the relationship between circulating tumor cells and clinicopathologic findings, compared with that of serum squamous cell carcinoma (SCC) antigen and carcinoembryonic antigen (CEA), in ESCC. METHODS Blood samples from 54 consecutive patients were obtained from the peripheral artery and the superior vena cava at three points in time: immediately before surgery, and before and after tumor resection. CEA-specific reverse transcriptase-polymerase chain reaction (RT-PCR), which can quantify circulating tumor cells in blood, was performed. The preoperative values of serum SCC antigen and CEA were also obtained for all patients. RESULTS CEA messenger RNA (CEA mRNA) was detected in the blood of 31 out of 54 patients (57.4%). CEA mRNA positivity was detected most frequently after tumor resection and correlated with nodal status and stage grouping. The incidence of total recurrence and blood-borne recurrence was significantly greater in patients with CEA mRNA positivity than in those with CEA mRNA negativity (P =.036 and.0026, respectively). Preoperative serum levels of SCC antigen and CEA did not correlate with clinicopathologic findings and tumor recurrence. CONCLUSIONS CEA mRNA detected by RT-PCR was more predictive of tumor recurrence than serum tumor markers. Effective adjuvant therapy is recommended for patients with CEA mRNA positive expression.

Abstract
Sentinel lymph nodes are the first draining nodes that contain tumor cells. Identification of sentinel nodes may help to determine the suitable extent of lymphadenectoy. To assess the location of sentinel lymph nodes, a series of 41 patients with single and two metastatic lymph nodes who underwent esophagectomy and 3-field lymphadenectomy between 1991 and 1999 were investigated retrospectively. Only 29 (47.5%) of 61 metastatic nodes showed correspondence between the tumor site and the regional metastatic lymph nodes by routine histologic examination. In the patients with tumors in the upper and middle thoracic esophagus, metastatic lymph nodes were distributed in the cervix, mediastinum and abdomen. Although sentinel nodes were limited to the regional and adjusting compartments in 82%, nodes were found beyond the adjusting compartments in 18%. The sentinel nodes were broadly distributed depending on the location of the tumor in esophageal cancer.
