Comparison of indocyanine green-near-infrared fluorescence guided and traditional mediastinal lymphadenectomy during radical esophagectomy: A randomized controlled trial. Surgery 2024; 175:347-352. [PMID: 38012899 DOI: 10.1016/j.surg.2023.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 09/02/2023] [Accepted: 10/24/2023] [Indexed: 11/29/2023]
Abstract
BACKGROUND The extent of lymph node dissection during radical esophagectomy remains a controversial topic. Thus, this study mainly aimed to explore the location of sentinel lymph nodes in esophageal squamous cell carcinoma and the application value of the indocyanine green-near-infrared fluorescence system in lymphadenectomy. METHODS This randomized controlled clinical trial (ClinicalTrials.gov, NCT04615806) included 42 participants without neoadjuvant therapy who were lymph node negative based on positron emission tomography/computed tomography findings. Traditional esophagectomy with indocyanine green-near-infrared fluorescence imaging was performed after injecting 0.5 mL indocyanine green (1.25 mg/mL) into the esophageal submucosa in the 4 peritumoral quadrants. The primary endpoint was to determine the location of the sentinel lymph node in esophageal squamous cell carcinoma based on postoperative pathologic reports. RESULTS A total of 40 patients, with 20 in each group, were included in the final analysis. In the indocyanine green group, indocyanine green-near-infrared fluorescence imaging was successful in all subjects. Seven cases (cases 2, 3, 9, 11, 17, 18, and 20) in the indocyanine green group exhibited lymph node metastases, all of which were near-infrared positive. The detection rate, positive predictive value, negative predictive value, sensitivity, and specificity were 100% (20 of 20 cases), 8.7% (13/150), 100% (265/265), 100% (13/13), and 65.9% (265/402), respectively. All near-infrared-negative lymph nodes were nonmetastatic lymph nodes. In addition, the number of mediastinal lymph nodes resected in the indocyanine green group was significantly higher than in the non-indocyanine green group. CONCLUSION Indocyanine green-near-infrared might be an important and promising technique in predicting sentinel lymph nodes of esophageal squamous cell carcinoma and could significantly improve the detection rate of lymph nodes of esophageal squamous cell carcinoma.

Abstract
Esophageal squamous cell carcinoma (ESCC) is a common malignant tumor of the digestive tract. The most effective method of reducing the disease burden in areas with a high incidence of esophageal cancer is to prevent the disease from developing into invasive cancer through screening. Endoscopic screening is key for the early diagnosis and treatment of ESCC. However, due to the uneven professional level of endoscopists, there are still many missed cases because of failure to recognize lesions. In recent years, along with remarkable progress in medical imaging and video evaluation technology based on deep machine learning, the development of artificial intelligence (AI) is expected to provide new auxiliary methods of endoscopic diagnosis and the treatment of early ESCC. The convolution neural network (CNN) in the deep learning model extracts the key features of the input image data using continuous convolution layers and then classifies images through full-layer connections. The CNN is widely used in medical image classification, and greatly improves the accuracy of endoscopic image classification. This review focuses on the AI-assisted diagnosis of early ESCC and prediction of early ESCC invasion depth under multiple imaging modalities. The excellent image recognition ability of AI is suitable for the detection and diagnosis of ESCC and can reduce missed diagnoses and help endoscopists better complete endoscopic examinations. However, the selective bias used in the training dataset of the AI system affects its general utility.

Abstract
The proportion of non-cancer death in patients with esophagus cancer (EC) still increasing, especially cardiovascular disease (CVD) related death. The aim of this study was assess non-cancer causes of death and identified independent risk factors of CVD related death in EC patients. Patients diagnosed with EC were extracted from the Surveillance, Epidemiology, and End Result database (SEER) database for analysis. Standardized mortality rates (SMRs) for non-EC deaths were calculated, the risk of death were assessed and compared with US general population. Multivariate competitive risk analysis were performed to select independent risk factors for death from CVD in EC patients. A total of 43739 EC patients were enrolled and 35139 died during follow-up, of which 4248 died from non-cancer cause of death. The risk of non-cancer death in EC patients was 2.27-fold higher than in the general population (SMR=2.27; 95% CI, 2.20-2.34). CVD were the most important cause of non-cancer death in EC patients, accounting for 43.4% of non-cancer of deaths. Compare with the general population, EC patients have higher risk of death from disease of heart (SMR, 2.24; 95% CI, 2.13-2.35), pneumonia and influenza (SMR, 2.92; 95% CI, 2.50-3.39), septicemia (SMR, 5.01; 95% CI, 4.30-5.79), along with other causes. Patients with advanced age and patients who received radiotherapy has higher risk of death caused by CVD, patients with female sex, poor differentiated and undifferentiated, regional and distant stage, married, diagnosed between 2010-2016 has lower risk of CVD related death, compared with patients without any treatment measures, patients received chemotherapy alone has lower risk of death from CVD. Non-cancer cause of death has become an important cause of death in EC patients. Improving public awareness of the major risk factors for non-cancer death is beneficial to the prevention and treatment of malignant tumors.

Abstract
INTRODUCTION The incidence and mortality rates of esophageal carcinoma are higher than those of most malignancies in humans. Radical esophagectomy is the preferred treatment for early-stage esophageal cancer. However, the extent of lymphadenectomy during radical esophagectomy remains controversial. Indocyanine green (ICG) is the most commonly used imaging agent for the diagnosis of tumors and metastatic lymph nodes in clinical settings. Thus, the main aim of this study was to evaluate pericancerous lymph nodes imaging in video-assisted thoracoscopic surgery radical esophagectomy using a near-infrared (NIR) ICG imaging system and to improve the detection rate of sentinel lymph nodes (SLNs) and overall survival of patients with esophageal cancer. METHODS This was a single-center, prospective, randomized controlled clinical trial (allocation rate = 1:1). Forty treatment-naive esophageal cancer patients were recruited and divided into two groups: the ICG and control groups. The inclusion criteria were age, absence of preoperative neoadjuvant therapy, elective surgery, and signed informed consent. Data of participants at four different time points (preoperation, intraoperation, postoperative 1 week and 3 months) were collected and recorded. The main endpoint of this study was to explore the accuracy and false-negative rate of lymphadenectomy using NIR-ICG fluorescence imaging and to identify the location of esophageal cancer SLN combined with postoperative pathological reports. DISCUSSION This trial will provide more evidence on the extent of lymph node dissection for esophageal cancer and contribute to the development of treatment guidelines for esophageal cancer.

Abstract
Background Near-infrared fluorescence image-guided surgery helps surgeons to see beyond the classical eye vision. Over the last few years, we have witnessed a revolution which has begun in the field of image-guided surgery. Purpose, and Research design Fluorescence technology using indocyanine green (ICG) has shown promising results in many organs, and in this review article, we wanted to discuss the 6 main domains where fluorescence image-guided surgery is currently used for esophageal and gastric cancer surgery. Study sample and data collection Visualization of lymphatic vessels, tumor localization, fluorescence angiography for anastomotic evaluation, thoracic duct visualization, tracheal blood flow analysis, and sentinel node biopsy are discussed. Conclusions It seems that this technology has already found its place in surgery. However, new possibilities and research avenues in this area will probably make it even more important in the near future.

Abstract
Background The right recurrent laryngeal nerve (RRLN) is the region most prone to lymph node metastasis in esophageal squamous cell carcinoma (ESCC). Nodal involvement may be underestimated by traditional imaging prediction criteria, such as a short axis diameter of 10 mm. The purpose of this study was to determine a more accurate imaging criterion to guide clinical treatment strategy selection. Methods The clinical data of 307 patients with thoracic ESCC who underwent surgery at Shanghai Chest Hospital between January 2018 and December 2018 were retrospectively analyzed. Utilizing 1-mm layer thickness enhanced computed tomography (CT), the RRLN lymph node short diameter (LNSD) size was measured. Univariate and multivariate analyses were performed to determine the risk factors for lymph node metastasis along the RRLN. Results In our study, RRLN lymph node metastasis occurred in 60 (19.5%) patients and general lymph node metastasis occurred in 150 (48.9%) patients. Of the resected lymph nodes along the RRLN, 14.5% (121/832) were positive. Multivariate analysis identified LNSD [odds ratio (OR), 1.236] as an independent risk factor for RRLN lymph node metastasis. In CT evaluation, a short diameter of 6.5 mm in the RRLN lymph nodes is a critical predictor of metastasis at this site (sensitivity =50%, specificity =83.4%) and a larger short diameter was associated with a higher risk of metastasis (P<0.001). Conclusions A 6.5 mm cutoff in LNSD can be applied to clinically predict lymph node metastasis in the RRLN region for patients with ESCC.

Abstract
BACKGROUND Recently, the feasibility of near-infrared (NIR) image-guided sentinel lymph node (SLN) mapping has been tested in patients with gastrointestinal cancer. The aim of this study is to investigate whether SLN mapping can be used to identify mediastinal lymph node metastases during minimally invasive esophagectomy and explore the lymphatic drainage pattern of esophageal squamous cell carcinoma (ESCC) using NIR fluorescent imaging. PATIENTS AND METHODS A total of 21 patients diagnosed with cT1-3 stage ESCC were enrolled. Patients received submucosal injection of indocyanine green diluted with sodium chloride (0.9%) at the start of the esophagectomy procedure followed by NIR mapping. RESULTS Thoracoscopic-assisted McKeown esophagectomy with NIR imaging was successfully performed in all patients. The detection rate and number of NIR+ lymph nodes were 95.2% (20/21) and 4.0 (2.0-6.5), respectively. The accuracy, false-negative rates, and negative predictive value were 100% (10 of 10 cases), 0% (0 of 4), and 100% (6 of 6), respectively, for pT1/T2 diseases; and 80.0% (8 of 10), 40% (2 of 5), and 71.4% (5 of 7), respectively, for pT3 diseases. The NIR+ region was the most commonly detected in the right recurrent laryngeal nerve (80%), and the NIR+ region was identified in the upper mediastinal zone in 20 patients. CONCLUSIONS Evaluation of the lymphatic drainage pattern and the application of sentinel lymph node in ESCC with real-time NIR imaging could be effective, especially in pT1/2 disease. NIR imaging-guided SLN navigation appears to be a clinically beneficial less-invasive method for treating ESCC.

Abstract
AIM To review the efficacy and outcomes of endoscopic resection in the diagnosis and treatment of oesophageal squamous dysplasia and early neoplasia. METHODS This was a retrospective study between May 2012-2018. Twenty-one patients were treated with or considered for treatment with endoscopic resection at a tertiary hospital in the UK. The primary outcome was curative resection, defined as histologically proven complete resection of the lesion with deep/vertical margin ≥1 mm from neoplasia. Secondary outcomes were changes in staging from endoscopic resection histology, whether there was a complete reversal of dysplasia at 12-months or the latest endoscopic follow-up and 5-year overall survival rate. RESULTS Seventeen patients (mean age = 66.5 years) with 20 lesions (35% en-bloc; 65% piecemeal resections) had endoscopic resection performed. Complete resection was achieved in 90% of lesions by endoscopic criteria, but this was confirmed in fewer lesions histologically. Curative resection was achieved histologically in 60% of lesions (11 patients) and noncurative resection in 40% of lesions (6 patients). Changes in staging from endoscopic resection histology were found in 79.2% of lesions (41.7% upstaged; 37.5% downstaged). No patients were found to have recurrence at their 12-month endoscopic follow-up. Eight of the 11 patients (72.7%) with curative resection remained clear of dysplasia/neoplasia throughout their follow-up (mean, 24.3 months; median, 19 months). The five-year overall survival rate was 64%. CONCLUSION In UK, endoscopic resection is useful in the management of early squamous neoplasia both for staging and (by piecemeal endoscopic resection in elderly unfit) for medium- to long-term disease clearance.

Abstract
AIMS To review the effectiveness of the revised Vienna classification (rVC) at predicting histological outcome and defining the postendoscopic resection (ER) clinical management plan of gastro-oesophageal dysplasia and early neoplasia in a UK tertiary-centre population. METHODS This was a retrospective cohort study between November 2011 and May 2018. 157 patients from Salford Royal NHS Foundation Trust in the UK were included. The primary outcome was the histological results of postsurgical resection (SR) specimens compared with their post-ER rVC. The secondary outcome was overall survival rates of patients with category 4.4 and 5 of the rVC. RESULTS One-hundred and thirteen patients were diagnosed with category ≥4 of the rVC. 23 patients (20.4%) were referred for additional surgery, whereas 69 patients (61.1%) were on endoscopic surveillance only. 60.9% of post-SR specimens (14/23) revealed no residual neoplasia. 78.6% of these cancer-free specimens were classed as category 5 rVC. The overall 7-year survival rate of 25 patients with category ≥4.4 was 68% with causes of mortality not linked to upper gastrointestinal neoplasia. The overall 7-year and 3-year survival rates of category 4.4 and 5 were 73.6% and 50%, respectively, although age and comorbid state played a role. CONCLUSIONS This study provides evidence of outcomes comparable to other reported cohorts for cases after ER in a single-centre UK population even at rVC 4.4/5. It suggests surgery may not be necessary in all cases due to the lack of residual disease and further refinement of the rVC category 5 may help guide management.

Introduction: This systemic review provides an overview of metabolic perturbations and possible mechanisms in gastrointestinal cancer. The authors discuss emerging challenges of technical and clinical applications.Areas covered: In this systemic review, the authors summarized the currently available results of metabolomic biomarkers linked to GI cancer, and discussed the altered metabolism pathways including carbohydrate metabolism, amino acid metabolism, lipids, and nucleotide metabolism and other metabolisms. Furthermore, future efforts need to adhere to normalize analysis procedures, validate with the larger cohort and utilize multiple-omics technologies. The search was conducted in PubMed with the following search terms (biomarker, gastrointestinal cancer, colorectal cancer, and esophageal cancer) from 2013 to 2019.Expert opinion: This systemic review summarized the currently available results of metabolomic biomarkers linked to gastrointestinal cancer, and discussed the altered metabolism pathways. The authors believe that metabolomics will benefit deeper understandings of the pathogenic mechanism, discovery of biomarkers and aid the search for drug targets as we move toward the era of personalized medicine. Personalized medication for tumors can improve the curative effect, avoid side effects and medical resource waste. As a promisingtool, metabolomics that targets the entire cancer-specific metabolite network should be applied more widely in cancer research.

Recommendation for the definition of postoperative radiotherapy target volume based on a pooled analysis of patterns of failure after radical surgery among patients with thoracic esophageal squamous cell carcinoma. Radiat Oncol 2018; 13:255. [PMID: 30587211 PMCID: PMC6307221 DOI: 10.1186/s13014-018-1199-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2018] [Accepted: 12/05/2018] [Indexed: 12/22/2022] Open
Abstract
Background Elective use of radiation therapy to treat regionally involved lymph nodes (LNs) after radical surgery for esophageal squamous cell carcinoma (ESCC) is controversial. We studied metastasis patterns through a pooled analysis of published results to guide post-operative radiotherapy (PORT) target designation. Methods We searched the MEDLINE database for literature published from May 1977 to March 2018, and found 14 relevant original studies that included 2738 patients with thoracic ESCC. We calculated probabilities of recurrence and metastasis in local (including anastomoses and tumor bed), LNs and distal areas. Results Recurrence rates were 1.88% for local, 13.18% for distal, and 22.16% for LNs. Within LNs, recurrence rates were cervical/supraclavicular: 37.69%, upper mediastinal: 44.30%, middle mediastinal: 21.81%, lower mediastinal: 2.57%, abdominal paraaortic: 25% and upper abdominal: 9.56%. Whereas cervical/supraclavicular and upper mediastinal LNs had the highest recurrence rates, abdominal LNs also had high recurrence rates in patients with lower thoracic ESCC. Conclusions PORT volume should include the cervical/supraclavicular and upper mediastinal LNs for all thoracic ESCC, and abdominal paraaortic LNs for lower thoracic ESCC. Anastomoses and tumor beds should not be included in the PORT volume if they are not adjacent to the PORT-LN regions. Upper abdominal LNs might not necessarily be included in the PORT volume for thoracic ESCC.

Abstract
BACKGROUND The aim of this study is to investigate the utility of total mediastinal lymphadenectomy (ML) in superficial esophageal squamous cell carcinoma (ESCC). METHODS The medical records of 129 patients who underwent esophagectomy and lymph node dissection for pathologically confirmed pT1 ESCC between July 2006 and December 2014 were retrospectively reviewed. Limited ML, such as traditional 2-field or transhiatal esophagectomy, was performed in 42 patients (group 1), and total ML, including the bilateral recurrent laryngeal nerve nodes, was performed in 87 patients (group 2). RESULTS R0 resection was achieved in all patients, and the number of dissected nodes was 28.0 ± 11.4 and 44.8 ± 16.1 in groups 1 and 2 (p < 0.001), respectively. The complication profile was similar in the two groups, but there were two operative mortalities in group 2. During a median follow-up of 32.4 months, loco-regional failure was found in 14.3% of group 1 and 3.5% of group 2 (p = 0.001). There was a significant difference in the 3-year overall survival (95.1% in group 2 vs. 83.3% in group 1, p = 0.043), and the 3-year disease-free survival rates (92.3% in group 2 vs. 73.7% in group 1, p = 0.001). On multivariate analysis, the extent of ML (HR, 5.200; 95% CI, 1.532 ~ 17.645; p = 0.008) and pT1b lesion classification (HR, 4.747; 95% CI, 1.024 ~ 21.997; p = 0.047) was a factor predictive of disease-free survival. CONCLUSIONS Total ML might be beneficial, especially in cases of pT1b ESCC, because it could lead to a lower incidence of recurrence and longer survival times.

Prediction of the invasion depth of superficial squamous cell carcinoma based on microvessel morphology: magnifying endoscopic classification of the Japan Esophageal Society. Esophagus 2017; 14:105-112. [PMID: 28386209 PMCID: PMC5362661 DOI: 10.1007/s10388-016-0527-7] [Citation(s) in RCA: 193] [Impact Index Per Article: 27.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2015] [Accepted: 02/09/2016] [Indexed: 02/03/2023]
Abstract
Predicting invasion depth of superficial esophageal squamous cell carcinoma is crucial in determining the precise indication for endoscopic resection because the rate of lymph node metastasis increases in proportion to the invasion depth of the carcinoma. Previous studies have shown a close relationship between microvascular patterns observed by Narrow Band Imaging magnifying endoscopy and invasion depth of the superficial carcinoma. Thus, the Japan Esophageal Society (JES) developed a simplified magnifying endoscopic classification for estimating invasion depth of superficial esophageal squamous cell carcinomas. We conducted a prospective study to evaluate the diagnostic values of type B vessels in the pretreatment estimation of invasion depth of superficial esophageal squamous cell carcinomas utilizing JES classification, the criteria of which are based on the degree of irregularity in the microvascular morphology. Type A microvessels corresponded to noncancerous lesions and lack severe irregularity; type B, to cancerous lesions, and exhibit severe irregularity. Type B vessels were subclassified into B1, B2, and B3, diagnostic criteria for T1a-EP or T1a-LPM, T1a-MM or T1b-SM1, and T1b-SM2 tumors, respectively. We enrolled 211 patients with superficial esophageal squamous cell carcinoma. The overall accuracy of type B microvessels in estimating tumor invasion depth was 90.5 %. We propose that the newly developed JES magnifying endoscopic classification is useful in estimating the invasion depth of superficial esophageal squamous cell carcinoma.

Abstract
BACKGROUND Endoscopic approaches are gradually considered as a reliable treatment of intramucosal esophageal squamous carcinoma. However, endoscopic resection (ER) is limited by the potential lymph node metastasis (LNM) at various depths of mucosal and submucosal invasion. METHODS We conducted a retrospective review of 498 patients with pT1 superficial esophageal squamous carcinoma (SESC) who underwent surgical resection from January 2008 to August 2015. Pathological characteristics of tumors including location, size, appearance, differentiation, invasion depth, and nodal status were reviewed, and risk factors were analyzed. RESULTS LNM was found in 0.0, 2.7, 6.3, 18.2, 15.9, and 34.3 % of the m1, m2, m3, sm1, sm2, and sm3 lesions, respectively. Univariate logistic regression identified the presence of the tumor size > 2 cm (p < 0.05), the presence of the poor tumor differentiation (p < 0.05), and the depth of tumor invasion (p < 0.05) and angiolymphatic invasion (p < 0.05) to be the important risk factors associated with the prevalence of tumor-positive lymph nodes. These findings were confirmed in multivariate logistic regression as independent predictors for LNM. CONCLUSIONS ER is considered as a reliable treatment of m1 to m2 lesions. Radical surgical resection (SR) is the standard and irreplaceable therapy of sm1 to sm3 lesions. Patients with m3 lesions should undergo ER as the initial procedure for diagnosis. And this treatment is supported only by a successful description of the tumor's characteristics, including (1) only muscularis mucosa invasion and without invasion of the resection margins and (2) without any risk predictors for LNM. Otherwise, SR is recommended.

Abstract
We performed a metabolomics study using liquid chromatography-mass spectrometry (LC-MS) combined with multivariate data analysis (MVDA) to discriminate global urine profiles in urine samples from esophageal squamous cell carcinoma (ESCC) patients and healthy controls (NC). Our work evaluated the feasibility of employing urine metabolomics for the diagnosis and staging of ESCC. The satisfactory classification between the healthy controls and ESCC patients was obtained using the MVDA model, and obvious classification of early-stage and advanced-stage patients was also observed. The results suggest that the combination of LC-MS analysis and MVDA may have potential applications for ESCC diagnosis and staging. We then conducted LC-MS/MS experiments to identify the potential biomarkers with large contributions to the discrimination. A total of 83 potential diagnostic biomarkers for ESCC were screened out, and 19 potential biomarkers were identified; the variations between the differences in staging using these potential biomarkers were further analyzed. These biomarkers may not be unique to ESCCs, but instead result from any malignant disease. To further elucidate the pathophysiology of ESCC, we studied related metabolic pathways and found that ESCC is associated with perturbations of fatty acid β-oxidation and the metabolism of amino acids, purines, and pyrimidines.

Abstract
Background To compare the right and left transthoracic approach on the post-operative survival of patients with lymph node-negative esophageal squamous cell carcinoma. Methods Six hundred and ninety-five ESCC patients who underwent esophagectomy between 1990 and 2005 were retrospectively enrolled in the present study and were confirmed by histology to be of no lymph node metastasis. Those who had received neoadjuvant chemotherapy or radiotherapy were excluded from the study. Patients were divided into two groups, the left (n = 545) and right (n = 150) transthoracic groups. The follow-up duration ranged from 1 to 20 years with a mean of 7 years. Kaplan–Meier and univariate and multivariate Cox proportional hazards were used for analysis. Results 3- and 5-year CSS rates were 62.0 % and 44.0 % in the left group, while the corresponding figures in the right group were 56.0 % and 40.0 %(P < 0.05). The overall survival for the two groups was significantly different (P = 0.045). Survival analyses were stratified by stages, which found that the favorable survival advantage was not present. When the survival curves were stratified by tumor locations, a significant difference was not revealed. Surgical approaches were regarded as one of the prognostic factors in the univariate analysis (P = 0.019). However, this significance could not be confirmed in multivariate Cox regression analysis (P = 0.193). Conclusions The left transthoracic approach is superior in some aspects to the right transthoracic approach regarding surgical and oncological outcomes in the treatment of lymph node negative ESCC.

Abstract
BACKGROUND This study evaluated patterns of treatment failure (especially locoregional failure; LRF) after radical esophagectomy and proposes a clinical target volume (CTV) for postoperative radiotherapy (PORT) among patients with thoracic esophageal squamous cell carcinoma (SCC). METHODS All patients who were followed up in our center after radical esophagectomy between 2007 and 2011 were retrospectively enrolled. The patterns of first discovered failure were assessed, and LRFs (including anastomotic and regional lymph node recurrences) were evaluated to determine whether our proposed PORT CTV encompassed these areas. The clinicopathologic factors predictive of lymphatic recurrence type were analyzed. RESULTS Of the 414 patients who underwent surgery and were followed up over the study, 207 experienced recurrent or metastatic diseases. The median time to progression was 11.0 months. Of the 173 patients with locoregional recurrence, nodal failure recurred in 160; supraclavicular and superior mediastinal lymph nodes had the highest metastasis rates. All 233 recurrent sites across the 160 patients were located in a standard CTV area, including the bilateral supraclavicular areas, the entire mediastinum, and the left gastric lymphatic drainage region. A total of 203 sites (87.2%) were located in either the bilateral supraclavicular areas or the entire mediastinum, and 185 sites (79.4%) were located in either the bilateral supraclavicular areas or the upper mediastinum. A multivariate analysis revealed the lymph node metastatic ratio (LNMR) and tumor differentiation were risk factors for nodal failure. CONCLUSIONS Locoregional recurrence (especially lymph node recurrence) was the most common and potentially preventable type of initial treatment failure after curative surgery among patients with thoracic esophageal SCC. The proposed PORT CTV covered most LRF sites. The lymphatic drainage regions for PORT are selective, and the supraclavicular and superior mediastinal areas should be considered. However, the value of PORT and the extent of CTV should be investigated in further prospective studies.

Abstract
BACKGROUND CC-chemokine receptor 7 (CCR7), a known lymph node homing receptor for immune cells, has been reported as a key molecule in lymph node metastasis. We hypothesized a clinicopathological correlation and functional causality between CCR7 expression and lymph node metastasis in patients with esophageal squamous cell carcinoma (ESCC). METHODS We performed immunohistochemical analysis of 105 consecutive and 61 exclusive pathological T1 ESCC patients, followed by adhesion assay and in vivo experiment using a newly developed lymph node metastasis mouse model. The adhesive ability in response to CC-chemokine ligand 21/secondary lymphoid-tissue chemokine (CCL21/SLC) was assessed in the presence or absence of lymphatic endothelial cells and anti-CCR7 antibody. We established a heterotopic transplantation mouse model and analyzed lymph node metastasis by quantitative real-time RT-PCR. RESULTS Positive CCR7 expression in immunohistochemistory was detected in 28 (27%) of 105 consecutive patients and 17 (28%) of 61 T1 patients, which significantly correlated with lymph node metastasis (p = 0.037 and p = 0.040, respectively) and poor five-year survival (p = 0.013 and p = 0.012, respectively). Adhesion assay revealed an enhanced adhesive ability of CCR7-expressing cells in response to CCL21/SLC, in particular, in the presence of lymphatic endothelial cells (p = 0.005). In the mouse model, lymph nodes from mice transplanted with CCR7-expressing cells showed significantly higher DNA levels at 5 weeks (p = 0.019), indicating a high metastatic potential of CCR7-expressing cells. CONCLUSION These results demonstrated the significant clinicopathological relationship and functional causality between CCR7 expression and lymph node metastasis in ESCC patients.

Abstract
Determination of the risk of lymph-node metastasis is crucial in making appropriate surgical or endoscopic resection therapeutic decisions. The actual number of patients with esophageal adenocarcinomas and esophagogastric junction adenocarcinomas remains relatively low in Japan; therefore, debate still exists as to whether or not intramucosal esophageal adenocarcinoma has a risk of lymph-node metastasis. We report herein a case of lymph-node metastasis in a surgical resection of an esophageal adenocarcinoma with muscularis mucosae invasion, but no lymphovascular involvement.

Abstract
BACKGROUND The purpose of this study was to evaluate long-term prognosis and cause of death in patients with superficial esophageal adenocarcinoma (SEAC) after surgery. PATIENTS AND METHODS A total of 85 patients without adjuvant or neoadjuvant treatment underwent surgery for SEAC (pT1N0-1, M0) 1984-2011. Medical records and causes of death were reviewed, and 79 specimens (93 %) were reanalyzed for cancer penetration. Survival was calculated according to Kaplan-Meier and comparisons of survival with log-rank test. Multivariate survival was analyzed with Cox proportional hazards model. RESULTS Of 85 patients, 36 had transhiatal, 33 transthoracic en bloc, 6 minimally invasive en bloc, 5 vagal sparing esophageal resection and 5 endoscopic mucosal resections; 7 patients (8 %) had lymph node metastasis (LNM). Cancer penetration: 35 pT1a and 44 pT1b. Overall survival was 67 % at 5 years and 50 % at 10 years. Disease-specific survival was 82 % at 5 years and 78 % at 10 years. Recurrence-free survival was 80 % at 5 years. In a Cox multivariate model, poor overall survival was predicted only by LNM. Cumulative mortality during median follow-up of 5 years (0-25 years): 37 of 85 (44 %). Cause of death of these 37: SEAC recurrence for 15 (41 %), postoperative complications for 4 (11 %), another primary malignancy for 5 (14 %), non-cancer-related for 11 (30 %) and for 2 (5 %) cause unknown. Mortality after 5-year follow-up: 11 (30 %); 82 % of these deaths were unrelated to SEAC recurrence. CONCLUSIONS With SEAC recurrence as the single most common cause of death, disease-specific 5-year survival was good. Overall and late (> 5-year) survival is affected by diseases related to aging.

Abstract
More studies are needed to clarify treatments and prognosis of early esophageal squamous cell carcinoma (ESCC). This retrospective study was designed to review the outcome of surgical treatment for early ESCC, evaluate the results of a left thoracotomy for selected patients with early ESCC, and identify factors affecting lymph node metastases and survival. The clinicopathological data of 228 patients with early ESCC who underwent transthoracic esophagectomy with lymphadenectomy without preoperative adjuvant treatment were reviewed. The χ(2) test or Fisher's exact test were used to detect factors related to lymph node metastasis. Univariate and multivariate analyses were performed to identify prognostic factors. There were 152 males and 76 females with a median age of 55 years. Two hundred and eight patients underwent a left thoracotomy, and the remaining 20 patients with lymph nodes in the upper mediastinum more than 5 mm in short-axis diameter by computed tomography scan underwent a right thoracotomy. No lymph node metastasis was found in the 18 patients with carcinoma in situ, while lymph node metastases were detected in 1.6% (1/62) of patients with mucosal tumours and 18.2% (27/148) of patients with submucosal tumours. Only 7 patients showed upper mediastinal lymph node metastases in the follow-up. The 5- and 10-year overall survival rates were 81.4% and 70.1%, respectively. Only histologic grade (P<0.001) and pT category (P=0.001) significantly correlated with the presence of lymph node metastases. In multivariate analysis, only histologic grade (P=0.026) and pT category (P=0.008) were independent prognostic factors. A left thoracotomy is acceptable for selected patients with early ESCC. Histologic grade and pT category affected the presence of lymph node metastases and were independent prognostic factors for early ESCC.

Abstract
BACKGROUND Oesophageal cancer is a global heath problem. The prognosis for advanced oesophageal cancer is generally unfavourable, but early-stage asymptomatic oesophageal cancer is basically curable and could achieve better survival rates. The two most commonly used tests are cytologic examination and endoscopy with mucosal iodine staining. The efficacy of the screening tests is controversial, and the true benefit and efficacy of screening remains uncertain because of the potential lead-time and length-time biases. This review was conducted to examine the evidence for the efficacy of screening for oesophageal cancer (squamous cell carcinoma and adenocarcinoma). OBJECTIVES To determine the efficacy of early screening, using endoscopy with iodine staining or cytologic examination, in reducing mortality from oesophageal cancer in asymptomatic individuals from high-risk and general populations. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2012, Issue 8), The Cochrane Library (2012, Issue 8), MEDLINE (1950 to August 2012), EMBASE (1980 to August 2012), Allied and Complementary Medicine (AMED) (1985 to August 2012), Chinese Biomedical Database (CBM) (January 1975 to August 2012), VIP Database (January 1989 to August 2012), China National Knowledge Infrastructure (CNKI) (January 1979 to August 2012), and the Internet. We also searched reference lists, conference proceedings, and databases of ongoing trials. There was no restriction on language or publication status in the search for trials. SELECTION CRITERIA We included only randomised controlled trials (RCT) of screening versus no screening for oesophageal cancer. Randomisation of groups or clusters of individuals was acceptable. DATA COLLECTION AND ANALYSIS Two review authors independently scanned the titles and abstracts from the initial search for potential trials for inclusion. We did not find any trials that met the inclusion criteria. MAIN RESULTS The electronic search identified 3482 studies. Two authors independently reviewed the references. The reports of 18 studies were retrieved for further investigation. None met the eligibility criteria for a RCT investigation of the effects of screening versus no screening for oesophageal cancer. AUTHORS' CONCLUSIONS There were no RCTs that determined the efficacy of screening for oesophageal cancer. Non-RCTs showed a high incidence and the reported better survival after screening could be caused by selection bias, lead-time and length-time biases. RCTs are needed to determine the efficacy of screening for oesophageal cancer.

Abstract
OBJECTIVE To identify differences in survival of patients with pT1 esophageal cancer relating to depth of wall infiltration. BACKGROUND DATA Histologic analysis of mucosal and submucosal infiltration in thirds has shown an increasing rate of lymph node metastases (LNM) according to the depth of wall infiltration in pT1 esophageal cancer. METHODS One hundred seventy-one patients had transthoracic en bloc (n = 161) or transhiatal esophagectomy (n = 10) for pT1 esophageal cancer [121 adenocarcinomas (AC), 50 squamous cell carcinomas (SCC)]. The histologic analysis of the specimen comprised depth of wall penetration of the carcinoma in thirds of pT1a = mucosa (m1, m2, m3) or pT1b = submucosa (sm1, sm2, sm3) and number and infiltration of the resected lymph nodes. RESULTS The rate of LNM was 0% for 70 mucosal carcinomas and 34% for 101 submucosal carcinomas (P = 0.001). For sm1, this rate was 13%, for sm2 19% and for sm3 56%. The 5-year survival rate (5Y-SR) was 82% for pN0 and 45% for pN+ patients (P < 0.001). There was no significant prognostic difference between AC and SCC (5Y-SR: 74% vs 71%). The 5Y-SR of the pT1a group was 87% compared with 66% for pT1b (P = 0.046). The 5-year survival rate for sm1 and sm2 were similar; sm1 + sm2 were together significantly better (80%) than sm3 (46%) (P = 0.008). In multivariate analysis, only sm3 was an independent prognostic factor (P = 0.01). CONCLUSIONS After esophagectomy, the prognosis of patients with sm1/sm2 infiltration is as good as for patients with mucosal carcinoma. Sm3 infiltration is the worst prognostic factor in pT1 esophageal cancer.

Abstract
There has been much recent debate regarding the best surgical procedure to treat esophageal cancer, in particular with regard to the optimum extent of lymphadenectomy to improve survival while minimizing morbidity. No results obtained by prospective, randomized studies on the comparison of radical esophagectomy and extended lymphadenectomy with limited or less invasive resections following neoadjuvant therapy with regard to perioperative morbidity and prognosis are available to date. Until now, there has been no evidence suggesting the usefulness of sentinel lymph node navigation in esophageal cancers, regardless of the cell type. Furthermore, the question as to the benefits and risks of two-field and three-field lymphadenectomy in esophageal cancer has not yet been conclusively answered. This article will discuss the recent status of lymph node-dissection procedures stage-dependently according to the two different tumor entities and with regard to minimally invasive esophagectomy, including the novel 2010 Tumor, Node, Metastasis-staging system.

Abstract
BACKGROUND The sentinel lymph node (SLN) concept has been gaining attention for gastrointestinal neoplasms but remains controversial for esophageal cancer. This study evaluated the feasibility of SLN identification using intraoperative indocyanine green (ICG) fluorescence imaging (IGFI) navigated by preoperative computed tomographic lymphography (CTLG) to treat superficial esophageal cancer. METHODS Subjects comprised 20 patients clinically diagnosed with superficial esophageal cancer. Five minutes after endoscopic submucosal injection of iopamidol around the primary lesion using a four-quadrant injection pattern with a 23-gauge endoscopic injection sclerotherapy needle, three-dimensional multidetector computed tomography was performed to identify SLNs and lymphatic routes. ICG solution was injected intraoperatively around the tumor. Fluorescence imaging was obtained by infrared ray electronic endoscopy. Thoracoscope-assisted standard radical esophagectomy with lymphadenectomy was performed to confirm fluorescent lymph nodes detected by CTLG. RESULTS Lymphatic vessels and SLNs were identified preoperatively using CTLG in all cases. Intraoperative detection rates were 100% using CTLG and 95% using IGFI. Lymph node metastases were found in four cases, including one false-negative case with SLNs occupied by bulky metastatic tumor that were not enhanced with both methods. The other 19 cases, including three cases of metastatic lymph nodes, were accurately identified by both procedures. CONCLUSIONS Preoperative CTLG visualized the correct number and site of SLNs in surrounding anatomy during routine computed tomography to evaluate distant metastases. Referring to CTLG, SLNs were identified using IGFI, resulting in successful SLN navigation and saving time and cost. This method appears clinically applicable as a less-invasive method for treating superficial esophageal cancer.

Abstract
BACKGROUND Both endoscopic and surgical treatments are recommended for m3- or sm1-adenocarcinomas of the esophagus, depending on patients' lymph nodal status. Lymphatic dissemination is related to tumor infiltration depth, but varying incidences have been reported in m3- and sm1-adenocarcinomas. The study aim was to investigate whether the presence of occult tumor cells in lymph nodes could explain this variation. METHODS Sixty-three node-negative (N0) patients with early esophageal adenocarcinoma (m2/m3/sm1-tumors) were included. Multilevel-sectioning of lymph nodes was performed; sections were stained by means of immunohistochemistry with cytokeratin marker CAM5.2. Two pathologists searched for micrometastases (0.2-2.0 mm) and isolated tumor cells (ITCs, <0.2 mm). RESULTS Positive CAM5.2 staining in lymph nodes was not seen in any of the 18 m2-patients. In 2/25 m3-tumors (8.0%) an ITC was found, but no micrometastases. Tumor cells were identified in 4/20 sm1-tumors (20.0%): three micrometastases and one ITC. Median follow-up was 121 months. Two m3-patients (3.2%) died due to disease recurrence, including one patient in whom an ITC was detected. CONCLUSIONS Lymphatic migration of tumor cells was found in node-negative m3- and sm1-adenocarcinomas of the esophagus (8.0% and 20.0%, respectively). However, the clinical relevance of these occult tumor cells should become apparent from large series of endoscopically treated patients.

Abstract
INTRODUCTION Radical esophagectomy is considered the standard therapy for tumors that infiltrate the submucosa of the esophagus (T1b), as the prevalence of lymph node metastases has been reported in up to 40% of these patients. It remains unclear whether radical esophagectomy with extended lymphadenectomy is needed or whether a surgical procedure with only regional lymphadenectomy suffices. The aim of this study was to compare outcomes of patients who underwent esophagectomy for T1b cancer through a transthoracic approach with extended lymphadenectomy (TTE) with those of patients in whom transhiatal esophagectomy (THE) was performed with a regional lymph node dissection. METHODS Patients who underwent esophagectomy for T1b cancer between 1990 and 2004 and who did not receive (neo)adjuvant therapy were included. Data were collected from prospective databases of 4 centers. In Leuven, Belgium (n = 101), and Los Angeles, CA (n = 31), patients with T1b tumors had been operated on via TTE with extended lymphadenectomy, whereas in Amsterdam (n = 43) and Rotterdam (n = 47), the Netherlands, THE with regional lymphadenectomy had been performed. RESULTS The 2 patient groups (TTE, n = 132; THE, n = 90) were comparable with regard to age, body mass index, and ASA classification. Operative time was longer in patients who underwent TTE (390 minutes) versus THE (250 minutes) (P < 0.001). The yield of lymph nodes resected was higher in the TTE group (median: 32) versus THE (median: 10) (P < 0.001). Overall morbidity, in-hospital mortality, and length of hospital stay were comparable between both the groups. In the TTE group, 27.3% of complications were classified as major versus 14.4% in the THE group (P < 0.001); however, the reoperation rate was higher after THE (12.2%) versus TTE (3.8%) (P = 0.01). There was no difference in pathological outcomes (infiltration depth, pN stage, pM stage, positive lymph node ratio) between both groups. Overall, 5-year survival (63.4% TTE vs 69.4% THE; P = 0.55) and disease-free 5-year survival (76.9% TTE vs 78.3% THE; P = 0.65) were comparable between both the groups. In patients with N1 disease, disease-free 5-year survival was 49.8% in the TTE group versus 40.0% in the THE group (P = 0.57). CONCLUSIONS In patients with submucosal esophageal cancer (T1b), TTE with extended lymphadenectomy and THE with regional lymphadenectomy had similar short-term outcome and long-term survival. In the selected group of T1bN1 patients, TTE may be the preferred operative technique because of a potential disease-free survival benefit; in patients with T1bN0 disease, THE with en bloc dissection of the esophagus and regional lymph nodes offers an oncologically safe and less invasive treatment.

Abstract
INTRODUCTION For patients with esophageal carcinoma limited to the mucosa endoscopic mucosal resection (EMR) is the therapy of choice whereas surgical resection is advocated for submucosal tumors. METHODS This study analyzes the histopathologic results of patients with early esophageal carcinoma who underwent EMR prior to transthoracic esophagectomy. Sixteen patients with early esophageal carcinoma and EMR as first line treatment were included in this retrospective study. Ten patients underwent transthoracic esophagectomy because of submucosal infiltration combined incomplete tumor resection at the lateral/basal resection margin. In one patient each, surgical therapy was indicated due to submucosal infiltration or incomplete resection only. Three patients underwent surgical resection due to residual neoplasia within an esophageal stenosis following EMR. Surgical specimens were examined for pT and pN stage according to the UICC. RESULTS Three patients had a squamous cell carcinoma (SCC) and 13 patients an adenocarcinoma (AC), nine patients with a long segment Barrett's esophagus. The distribution of the pT stages was as follows: 6x pT0 (no histopathologic evidence of residual tumor), 1x pT1m1, 1x pT1m2, 3x pT1m3, 1x pT1sm1, 1x pT1sm2, 1x pT2, and 2x pT3. Three of 16 patients (18.8%) with a pT1sm1, pT2, and pT3 stage had nodal metastases. In all three patients metastatic nodes were located in the mediastinum. In two patients, a second carcinoma was detected during histopathologic work-up (1x AC in the cardia and 1x SCC in the cervical esophagus). CONCLUSION The data of this highly selected patients indicate that the boundary between the therapy of mucosal and submucosal tumors is not as clear as stated. Therefore, treatment of early esophageal carcinoma demands a close interdisciplinary cooperation.

Abstract
BACKGROUND The depth of tumor penetration is a crucial factor in determining the prognosis of patients with esophageal carcinoma. Patients with superficial esophageal carcinoma (SEC) have a far more favorable clinical course compared with those with advanced cancers. The outcome for patients with mucosal cancer is excellent with a 5-year survival rate exceeding 80%. On the other hand, submucosal cancer often metastasizes to regional and/or distant lymph nodes or other organs, and the prognosis of these patients are far from satisfactory. METHODS Among 334 patients with esophageal cancer who underwent surgery between December 1980 and December 2006, 100 patients (30%) had SEC confined to the epithelium, lamina propria mucosa, or submucosa. Patient and tumor characteristics of those 100 patients were studied. RESULTS The prevalence of SEC has increased from 13% (8 of 61) in the initial 5-year period (1985-1989) to 44% (41 of 93) in the recent 7-year period (2000-2006). Subjective symptoms were present in 7 (14%) of 51 mucosal cancers and in 13 (27%) of 49 submucosal cancers. The remaining 80 patients (80%) had no subjective symptoms. Ninety-one patients (91%) were diagnosed to have the lesions by endoscopy at the time of screening for gastric problems, and only nine were detected by gastrointestinal series. Four of 51 patients with mucosal cancer had venous or lymph vessel invasion, and among those, only one (2%) had a solitary perigastric lymph node metastasis. In 49 patients with submucosal cancer, 35 (71%) had lymph vessel invasion, 28 (57%) had venous invasion, and 16 (33%) had lymph node metastases. In particular, 15 of 35 patients with positive lymph vessel invasion had lymph node metastasis, whereas only 1 of 14 with negative lymph vessel invasion had lymph node metastasis (P < .05). Among 17 patients with nodal involvement, 4 patients with upper thoracic SEC had upper mediastinum and/or cervical nodal metastases, 11 patients with middle thoracic SEC had widespread upper and lower mediastinal and abdominal metastases, and 2 patients with lower thoracic SEC had lower and abdominal lymph node metastases. Seventy-nine patients were alive without recurrence at last follow-up. Five of 49 patients with submucosal cancer died of recurrent disease, and 4 of these developed regional nodal recurrence around the bilateral laryngeal recurrent nerves. Forty-two patients (42%) developed double cancers during the follow-up period, and 5 died of a second cancer. The 3- and 5-year survival rates of all 100 patients were 85% and 73%, and those disease-specific survival rates were 96% and 93%, respectively. The 3- and 5-year survival rates for patients with mucosal cancer were 89% and 83%, and those for submucosal cancer were 80%, and 64%, respectively. CONCLUSIONS Esophagectomy with extensive lymphadenectomy should be carried out particularly for upper thoracic submucosal cancer, whereas esophagectomy with moderate lymphadenectomy may be preferred for mucosal cancer. Patients with SEC should be examined for another primary cancer preoperatively and periodically during follow-up.

Abstract
Sentinel lymph node biopsy (SLNB) has been developed as a new diagnostic and therapeutic modality in melanoma and breast cancer surgery. The purpose of the SLNB include preventing the operative morbidity and improving the pathologic stage by focusing on fewer lymph nodes using immunocytochemic and molecular technology has almost achieved in breast cancer surgery. The prognostic meaning of immunocytochemically detected micrometastases is also evaluating in the SLN and bone marrow aspirates of women with early-stage breast cancer. SLNB using available techniques have suggested that the lymphatic drainage of the gastrointestinal tract is much more complicated than other sites, skip metastasis being rather frequent because of an aberrant lymphatic drainage outside of the basin exist. At the moment, the available data does not justify reduced extent of lymphadenectomy, but provides strong evidence for an improvement in tumor staging on the basis of SLNB. Two large scale prospective multi-center trials concerning feasibility of gamma-probe and dye detection for gastric cancer are ongoing in Japan. Recent studies have shown favorable results for identification of SLN in esophageal cancer. CT lymphography with endoscopic mucosal injection of iopamidol was applicable for SLN navigation of superficial esophageal cancer. The aim of surgical treatment is complete resection of the tumor-infiltrated organ including the regional lymph nodes. Accurate detection of SLN can achieve a selection of a more sophisticated tailor made approach. The patient can make a individualized choice from a broader spectrum of therapeutic options including endoscopic, laparoscopic or laparoscopy-assisted surgery, modified radical surgery, and typical radical surgery with lymph node dissection. Ultrastaging by detecting micrometastasis at the molecular level and the choice of an adequate treatment improve the postoperative quality of life and survival. However these issues require further investigation.
