Cancer of the Esophagus
The esophagus (UK spelling: oesophagus) is a long hollow muscular tube which connects the throat to the stomach. Esophageal cancer is a disease where malignant (cancerous) cells arise in the tissues of the esophagus. The most common symptom is difficulty in swallowing. It can also be associated with weight loss and sometimes pain or discomfort behind the breast bone or in the back - these symptoms should be checked by a doctor but not are sure signs of cancer. There are two main types of esophageal cancer (depending on how the cells appear under the microscope); approximately half are classed as "squamous cell carcinomas" and half as "adenocarcinomas". People with frequent gastric reflux leading to Barrett's Esophagus have an increased risk of developing esophageal cancer.

Neoadjuvant Chemotherapy Increases PD-L1 Expression and CD8
Anticancer Res. 2019; 39(8):4539-4548 [PubMed] Related Publications
PATIENTS AND METHODS: Using a database of 69 ESCC patients, we analyzed PD-L1 expression on tumor cells (TCs) and immune cells (ICs), as well as the density of CD8
RESULTS: The fraction of ESCC containing ICs expressing PD-L1 and having a high CD8
CONCLUSION: NAC-FP induced PD-L1 expression on ICs and CD8
Is Oral Mucositis Occurring During Chemotherapy for Esophageal Cancer Patients Correctly Judged? EPOC Observational Cohort Study.
Anticancer Res. 2019; 39(8):4441-4448 [PubMed] Related Publications
MATERIALS AND METHODS: A central review system (CRS) was created to allow judgment when the patient background is completely unknown. The primary endpoint was the rate of grade 2 or higher OM, and the secondary endpoint was the difference in grade between each institution's clinician judgement and that of the CRS.
RESULTS: In total, 53 patients were registered from four institutions. CRS successfully detected grade 2 or higher OM in 16 (30.2%) of the 53 patients. The detection rate of all grades of OM was 41.5% (22 of 53 patients) by each institution's clinician judgement and 84.9% (45 of 53 patients) by CRS judgement (p<0.0001).
CONCLUSION: OM during chemotherapy may be underestimated.
Long-term Esophageal Cancer Survivor Treated by Bypass for Esophagobronchial Fistula After Chemoradiotherapy: A Case Report.
Anticancer Res. 2019; 39(8):4399-4403 [PubMed] Related Publications
CASE REPORT: A 44-year-old man was treated with definitive CRT (i.e. 66 Gy radiotherapy, chemotherapy with cisplatin, and 5-fluorouracil) for unresectable locally advanced esophageal cancer with massive invasion of the left main bronchus. Although a complete clinical response was obtained, the patient developed pneumonia due to an ERF. Esophageal bypass operation was performed for symptomatic relief. The patient's symptoms improved and oral ingestion became possible. No recurrence has been seen for 12 years.
CONCLUSION: Esophageal bypass surgery can help in relieving symptoms and might be associated with long-term survival for esophageal cancer patients with ERF after good response to CRT. Thus, bypass surgery is a useful option in the treatment for esophageal cancer with ERF.
Prognostic Value of Subcarinal Lymph Nodes in Minimally Invasive Esophagectomy for Cancer.
Anticancer Res. 2019; 39(8):4291-4295 [PubMed] Related Publications
PATIENTS AND METHODS: This is a retrospective analysis of consecutive esophagectomies for cancer, performed in a UK tertiary center. The study was conducted over a 3-year period.
RESULTS: The rate of subcarinal lymph-node invasion was extremely low according to the results of our analysis.
CONCLUSION: Lymphadenectomy is not devoid of clinical impact on patients and therefore, the decision should actually be the outcome of a dynamic balance between complications and survival benefit.
Is Concurrent Chemotherapy With Radiotherapy for Esophageal Cancer Beneficial in Patients Aged 80 Years or Older?
Anticancer Res. 2019; 39(8):4279-4283 [PubMed] Related Publications
PATIENTS AND METHODS: A total of 185 patients aged 80 years or older who were treated with definitive radiotherapy alone or combined with chemoradiotherapy for esophageal cancer at seven institutions were enrolled. In order to compare survival rates of patients treated with chemoradiotherapy with those of patients treated with radiotherapy alone, propensity score matching was performed to homogenize the two populations.
RESULTS: For the whole patient cohort, the 3-year overall survival (OS) rate was 52.6% and the median survival was 42.5 months. After propensity score matching, the 3-year OS rate for the chemoradiotherapy group was not significantly better than that for the group treated with radiotherapy alone (53.7% vs. 59.9%, p=0.876).
CONCLUSION: Concurrent chemotherapy with radiotherapy for esophageal cancer in patients aged 80 years or older did not have significant OS benefit over radiotherapy alone.
Efficacy of Percutaneous Endoscopic Gastrostomy for Patients With Esophageal Cancer During Preoperative Therapy.
Anticancer Res. 2019; 39(8):4243-4248 [PubMed] Related Publications
MATERIALS AND METHODS: We retrospectively reviewed 92 patients who underwent esophagectomy for EC after preoperative therapy. Patients were divided into the PEG group (n=14) and the control group (n=78) and compared regarding patient characteristics, nutritional status, operative variables, and postoperative complications.
RESULTS: In the PEG group first nutritional status and tumor stage were significantly worse, but changes of nutritional status from first visit to operation were significantly better. According to the intraoperative thermal imaging, there was no patient with blood flow disturbance in the gastric conduit due to PEG. Short-term surgical outcomes did not significantly differ.
CONCLUSION: PEG has less adverse effects on gastric tube production in esophagectomy and may be considered in highly selective patients during preoperative therapy.

Massive esophageal bleeding in long-standing achalasia complicated by esophageal carcinoma and aspirin-induced stasis ulcer: Case report.
Medicine (Baltimore). 2019; 98(30):e16519 [PubMed] Related Publications
PATIENT CONCERNS: We describe a case of a 64-year-old man with long-standing achalasia and megaesophagus who presented acute episodes of life-threatening upper gastrointestinal bleeding.
DIAGNOSES AND INTERVENTIONS: Five esophagogastroduodenoscopies (EGD) were conducted and during each large amount of static food, bloody material, and clots should be removed from the esophagus because of impaired esophageal transit. Eventually, diffuse multiple irregular ulcers were observed in the middle and lower portions of the esophagus that were presumed to have been caused by aspirin stasis based on considerations of previous drug use. EGD also revealed a 2.0 × 2.5 cm flat nodular lesion with central ulceration at the mid-to-lower esophagus and adherent blood clots suggestive of bleeding stigma. The biopsy specimen demonstrated esophageal cancer. Accordingly, a diagnosis of massive esophageal hemorrhage in long-standing achalasia complicated by squamous cell carcinoma, possibly triggered by acute mucosal irritation and ulcer caused by aspirin stasis, was made. The patient then successfully underwent the Ivor-Lewis operation. Resultantly, the tumor was diagnosed as moderately differentiated squamous cell carcinoma stage IIA (T2N0M0).
OUTCOMES: The patient's postoperative course was uneventful, and no evidence of tumor recurrence or metastasis has been found during the 6 months of follow-up examination. He was tolerating normal food with only minimal reflux symptoms.
LESSONS: Although, fortunately in the described case, esophageal cancer was diagnosed at a relatively early stage because it is the acute presentation of life-threatening upper gastrointestinal bleeding, this report cautions that when symptoms of dysphagia are aggravated, taking drugs capable of acting as local irritants, such as aspirin, could cause fatal esophageal hemorrhage in achalasia.

Ultrasonographic imaging of calcifying fibrous tumor of cervical esophagus: A case report.
Medicine (Baltimore). 2019; 98(28):e16425 [PubMed] Free Access to Full Article Related Publications
PATIENT CONCERNS: A 37 years old women was initially diagnosed thyroid nodule in local hospital. She was referred to receive microwave ablation of the nodule in our hospital. The patient was in good health with occasional foreign body sensation in the neck. Routine laboratory examination was normal.
DIAGNOSIS: The lesion was suspected benign and originating from the esophagus rather than the thyroid gland by conventional ultrasound and contrast-enhanced ultrasound in our hospital and was finally proved to be CFT by pathology.
INTERVENTIONS: The lesion was surgically removed.
OUTCOMES: The patient recovered well and was followed up for 2 years without recurrence.
LESSONS: Although imaging diagnosis of CFT is difficult, the findings of clear border, coarse calcification on conventional ultrasound and peripheral hypoenhancement without central enhancement on contrast-enhanced ultrasound (CEUS), together with real-time evaluation of the relationship between the tumor and esophagus help to distinguish CFT of cervical esophagus from other lesions in the neck.
MiR-216a-5p targets TCTN1 to inhibit cell proliferation and induce apoptosis in esophageal squamous cell carcinoma.
Cell Mol Biol Lett. 2019; 24:46 [PubMed] Free Access to Full Article Related Publications
Results: Here, we found that miR-216a-5p expression was significantly down-regulated in clinical ESCC tissues and cells. Functional assays were performed to evaluate the biological effects of miR-216a-5p on cell proliferation and cell apoptosis by CCK-8 assay and flow cytometry in ESCC cell lines, EC9706 and TE-9. The results showed that miR-216a-5p overexpression repressed cell proliferation and induced cell apoptosis. Through bioinformatics prediction and luciferase reporter assay, we revealed that miR-216a-5p could directly target tectonic family member 1 (TCTN1). Moreover, TCTN1 was obviously suppressed by miR-216a-5p overexpression. In addition, TCTN1 expression was significantly increased and inversely correlated with the levels of miR-216a-5p in ESCC tissues. More importantly, down-regulation of TCTN1 imitated, while restoration of TCTN reversed the effects of miR-216a-5p on cell proliferation and apoptosis. At the molecular level, we further found that TCTN1 overexpression reversed the effects of miR-216a-5p transfection on the expression of PCNA, Bcl-2 and Bad.
Conclusions: Our results demonstrate that miR-216a-5p might serve as a tumor suppressor in ESCC cells through negatively regulating TCTN1 expression, indicating the possibility that miR-216a-5p and TCTN1 might be attractive targets for ESCC therapeutic intervention.

S-1 Monotherapy After Failure of Platinum Plus 5-Fluorouracil Chemotherapy in Recurrent or Metastatic Esophageal Carcinoma.
Anticancer Res. 2019; 39(7):3931-3936 [PubMed] Related Publications
MATERIALS AND METHODS: The subjects of this study had RM-ESCC and received S-1 after failure of FP.
RESULTS: Eleven patients were enrolled. Nine patients were refractory and two were intolerant to prior FP. The median progression-free survival and overall survival time were 3.0 and 11.7 months, respectively. Overall response rate was 22.2% and disease control rate of the 11 patients was 36.4%. Median relative dose intensity of 5-FU was 100% (range=85-100%).
CONCLUSION: S-1 efficacy in RM-ESCC when given after FP was modest. Favorable OS may be attributed to good local control rather than to the efficacy of S-1 monotherapy.
Safety and efficacy of pulsed low-dose rate radiotherapy for local recurrent esophageal squamous cell carcinoma after radiotherapy: Study protocol for a prospective multi-center phase II trial.
Medicine (Baltimore). 2019; 98(26):e16176 [PubMed] Free Access to Full Article Related Publications
METHODS AND ANALYSIS: This study is a prospective, multi-center, open, single-arm clinical trial designed to enroll 27 patients with locally recurrent ESCC after radiotherapy with or without chemotherapy. Re-irradiation will be performed using intensity modulated radiation therapy in 50 Gy/25 fractions. The strategy of PLDR includes dividing 2 Gy into 10 fractions, and administering each irradiating dose of 20 cGy at an interval of 3 minutes before the next low-dose irradiation. The actual dose rate of administration each time will be 16.67 cGy /minute. The primary endpoint in this study is the rate of esophageal perforation. The secondary endpoints are the objective remission rate, the palliative effect on quality of life and pain, and the time of disease progression. The observation time is 2 years after the end of the study.

Fully covered self-expandable esophageal metallic stents in patients with inoperable malignant disease who survived for more than 6 months after stent placement.
Br J Radiol. 2019; 92(1100):20190321 [PubMed] Related Publications
METHODS: From January 2002 to January 2018, 88 FCSEMS were placed in 64 patients (mean age 62.9 ± 11.6 years; 58 males) with inoperable malignant esophageal obstruction with or without esophago-respiratory fistula. Only patients who survived more than 6 months with FCSEMS in place were included. Data regarding technical and clinical success, complications, reinterventions, stent patency, and patient survival were obtained from a prospectively maintained hospital database.
RESULTS: The technical and clinical success rates were 100 % (64/64). During follow-up, the median dysphagia score significantly improved (3.09 ± 0.68 to 1.05 ± 0.60,
CONCLUSIONS: Our data suggest that esophageal FCSEMS placement is an effective option for patients with malignant dysphagia when survival longer than 6 months is expected. The rate of complications increases with time, and SEMS development is needed to keep up with the advancement in oncological treatment.
ADVANCES IN KNOWLEDGE: Fully covered esophageal self-expandable stent placement is effective in patients surviving more than 6 months, however, the rate of complications also increases. SEMS development is needed to cope with the advancement in oncological treatment.
Aberrant expression of Sec61α in esophageal cancers.
J Cancer Res Clin Oncol. 2019; 145(8):2039-2044 [PubMed] Related Publications
MATERIALS AND METHODS: Here, we analysed the role of Sec61α in esophageal cancer, and we analysed Sec61α staining on a tissue microarray containing more than 600 esophageal cancer specimens by immunohistochemistry.
RESULTS: Sec61α staining was always strong in benign esophagus, but was only found in 5% of interpretable esophageal adenocarcinomas (EACs) and 14.5% of squamous cell carcinomas (ESCCs). Reduced Sec61α staining was not strongly linked to tumor phenotype in both subgroups of esophageal cancers and was unrelated to clinical outcome of patients (EACs: p = 0.8051 and ESCCs: p = 0.2751).
CONCLUSIONS: Thus, Sec61α measurement has not an additional prognostic benefit for the patients.
Minimally Invasive Circumferential Hiatal Dissection for the Treatment of Adenocarcinoma of the Distal Esophagus and Esophago-gastric Junction: Technical Considerations Combined With Histopathological Outcomes.
Anticancer Res. 2019; 39(6):3219-3225 [PubMed] Related Publications
PATIENTS AND METHODS: A prospective study of 40 consecutive patients undergoing hybrid (laparoscopic/thoracotomic) or totally minimally invasive Ivor-Lewis esophagogastrectomy over a period of 21 months was conducted. Dissection of the hiatus included peri-esophageal surrounding tissues in a cylindrical fashion maximizing the distance from the oesophageal wall. Crural muscle fibers and pleura bilaterally, pericardial fat anteriorly and pre-aortic tissue posteriorly were excised en bloc. Histopathological results particularly focused on involvement of the circumferential resection margin. Neoadjuvant chemotherapy was given to 24 (60%) patients.
RESULTS: Complete histological clearance (R0) was achieved in 92.5% (n=37) according to the criteria of the College of American Pathologists and in 87.5% (n=35) according to those of the Royal College of Pathologists. In pT3 tumors (n=22), the circumferential resection margin was negative in 20 patients (91%) according to the College of American Pathologists, and in 17 (77%) according to the Royal College of Pathologists.
CONCLUSION: Adoption of this safe and reproducible technique might reduce the incidence of circumferential resection margin involvement and improve pathological outcomes. In addition, there may be positive implications for training and quality control.
Thoracoscopic Oesophagectomy Using Prone Positioning for Oesophageal Cancer With Right Aortic Arch: A Case Report.
Anticancer Res. 2019; 39(6):3207-3211 [PubMed] Related Publications
PATIENTS AND METHODS: A 67-year-old man who presented with pharyngeal discomfort was admitted to our hospital. Further examinations revealed advanced thoracic EC accompanied with RAA and aortic diverticulum.
RESULTS: After neoadjuvant chemotherapy, we successfully and safely performed thoracoscopic oesophagectomy and lymphadenectomy using the prone positioning.
CONCLUSION: There exist only a few reports of thoracoscopic oesophagectomy for EC with RAA. Sufficient preoperative preparation and sharing an adequate strategy for the surgical approach with the surgical team are definitely necessary. Although the thoracoscopic approach for EC with RAA is useful, more considerations are needed for some issues.

Multidisciplinary Therapy for Locally Advanced Oesophageal Cancer With Special Reference to Surgical Conversion and Salvage.
Anticancer Res. 2019; 39(6):3167-3175 [PubMed] Related Publications
PATIENTS AND METHODS: A total of 147 patients who were diagnosed with clinical T4b oesophageal cancer were included in this study.
RESULTS: Forty-three patients had undergone curative resection of the tumour and surrounding invasion at midterm evaluation, 104 patients continued with definitive chemoradiotherapy, and salvage surgery was performed in 21 patients. Multivariate analysis of disease-specific survival showed that response at the midterm evaluation and surgical intervention (conversion surgery + salvage surgery) were significant prognostic factors.
CONCLUSION: Surgical intervention was an independent prognostic factor, and operation should be performed in eligible patients after considering the risks and proper timing.

Comparison of hand-sewn versus mechanical esophagogastric anastomosis in esophageal cancer: Protocol for a systematic review and meta-analysis.
Medicine (Baltimore). 2019; 98(23):e15676 [PubMed] Free Access to Full Article Related Publications
METHODS: We will perform a systematic electronic search of the PubMed, Embase, Cochrane Library, Web of Science for relevant articles published in English language. Pooled odds ratios will be calculated for the effect on discrete variables including anastomotic leakage, anastomotic strictures, 30-day mortality, quality of life, cardiac and pulmonary complications. The weighted mean difference was calculated for the effect size on continuous variables such as operative time and bleeding amount. We will use the software Review Manager 5.3 and STATA 14.0 to perform the meta-analysis to calculate the data synthesis.
RESULTS: The review will provide a high-quality synthesis of current evidence of the impact of different anastomosis methods on postoperative course in ECs after esophagectomy. The results will be published in a peer-reviewed journal.
CONCLUSION: This systematic review and meta-analysis will compare the different anastomosis methods in EC patients. The results will better offer some specific suggestions for esophagogastric anastomosis.
PROSPERO REGISTRATION NUMBER: This systematic review protocol has been registered in the PROSPERO network (No. CRD 42019109523).

Oncologic Resection in Laparoscopic Versus Robotic Transhiatal Esophagectomy.
JSLS. 2019 Apr-Jun; 23(2) [PubMed] Free Access to Full Article Related Publications
Methods: Thirty-six consecutive patients who underwent laparoscopic and robot-assisted THE for malignant disease over a 3-year period were identified in a retrospective database. Eighteen patients underwent robotic-assisted THE with cervical anastomosis, and 18 patients underwent laparoscopic THE. All procedures were performed by a single foregut and thoracic surgeon.
Results: Patient demographics were similar between the 2 groups with no significant differences. Lymph node yields for both laparoscopic and robot-assisted THE were similar at 13.9 and 14.3, respectively (
Conclusions: Laparoscopic and robot-assisted THEs yield similar perioperative oncologic results including lymph node yield and margin status. In the transition from laparoscopic surgery, robotic surgery should be considered oncologically noninferior compared with laparoscopy.
The prognostic value of pre-treatment prognostic nutritional index in esophageal squamous cell carcinoma: A meta-analysis.
Medicine (Baltimore). 2019; 98(22):e15280 [PubMed] Related Publications
METHODS: A comprehensive search of online databases (PubMed, Embase, Web of Science) was performed. Studies explored the relationship between pre-treatment PNI and long-term survival of ESCC patients were regarded eligible for this meta-analysis. Outcomes were extracted and synthesized. Hazard ratio (HR) and relative ratio (RR) with 95% confidence interval (CI) were used to evaluate the prognostic value of PNI on long-term survival and association with clinical-pathological features, respectively. The heterogeneity levels and publication bias between studies were also estimated.
RESULTS: Nine observational studies involving 2276 patients were considered eligible for this meta-analysis. The pooled results showed that low PNI score was significantly correlated with poorer overall survival (OS) of esophageal cancer (pooled HR = 1.418 95%CI: 1.200-1.676, P = .000), poorer recurrence free survival (HR = 1.880 95%CI: 1.207-2.929, P = .005) but not cancer specific survival (CSS) (HR = 1.948 95%CI: 0.544-6.977, P = .306). The PNI value was not related with patient age, sex, depth of tumor invasion, nodular metastasis, and differential grade but the TNM stage (III/IV vs 0/I/II, RR = 1.276, 95% CI 1.146-1.420).
CONCLUSIONS: Low pre-treatment PNI was significantly related with OS and recurrence free survival but not CSS for ESCC. PNI was a reliable prognostic factor of ESCC, and higher stage ESCC have higher incidence of low PNI.
CHROMOENDOSCOPY USING TOLUIDINE BLUE PLUS LUGOL'S SOLUTION FOR EARLY DIAGNOSIS OF ESOPHAGEAL PREMALIGNANT LESIONS AND SUPERFICIAL NEOPLASMS IN HIGH-RISK PATIENTS.
Arq Gastroenterol. 2019 Jan-Mar; 56(1):41-44 [PubMed] Related Publications
OBJECTIVE: This article aimed to determine the effectiveness of chromoendoscopy with toluidine blue combined with Lugol's solution for diagnosis of esophageal premalignant and superficial neoplastic lesions in high risk patients.
METHODS: Routine white light upper endoscopy was performed. Toluidine blue was sprayed from the gastroesophageal junction to 20 cm of the dental arch. Then the uptake dye areas were characterized. Later Lugol's solution was sprayed. Areas with less-intense staining were characterized. Biopsy of the toluidine blue capturing areas and areas with less-intense staining of Lugol's solution were taken. In the cases where lesions were not evidenced after application of dyes, biopsies four quadrants of the esophageal mucosa were taken. The samples were evaluated by a digestive pathologist.
RESULTS: Barrett's esophagus was the most common premalignant lesion and the early neoplastic lesion was adenocarcinoma with a sensitivity of 100%, specificity 85.7%, positive predictive value 30%, negative predictive value 100%, positive likelihood ratio 7 negative likelihood ratio 0.
CONCLUSION: Chromoendoscopy with toluidine blue combined with Lugol's solution is a useful tool in the screening of esophageal premalignant lesions and superficial neoplasms.
