Abstract
Background The aim of the present study is to identify the incidence and prognostic significance of lymph node metastases near the celiac trunk in patients who underwent neoadjuvant chemo(radio)therapy followed by esophagectomy. Methods Between March 1994 and September 2013 a total of 462 consecutive patients with cancer of the esophagus or gastroesophageal junction (GEJ) who underwent potentially curative esophageal resection after neoadjuvant chemotherapy (N=88; 19.0%) or neoadjuvant chemoradiotherapy (CRT) (N=374; 81.0%) were included. Results Seventy one (15.4%) patients had truncal node metastases in the resection specimen. Metastases to these nodes occurred more frequently in male patients with adenocarcinoma and in tumors at the gastro-esophageal junction. A lower response to neoadjuvant treatment, higher ypT and ypN stages and a poorer grade of differentiation were significantly related with truncal node metastases. Patients with tumor positive truncal nodes had a worse median overall survival (17 vs. 55 months). In multivariate analysis, truncal node metastases were independently associated with a worse survival. Only 22 (31.0%) of the 71 patients with tumor positive truncal nodes were identified preoperatively with EUS or CT. In contrast, 37 patients had suspicious truncal nodes on EUS or CT, but metastases in the pathology specimen were absent. Conclusions In the present study, it is demonstrated that positive truncal nodes in the resection specimen after neoadjuvant therapy, are associated with advanced tumor stages and are an independent factor for inferior survival.

Abstract
Endosonography (EUS) enables the acquisition of clear images of the gastrointestinal tract wall and the surrounding structures. EUS enables much greater accuracy for staging decisions compared to computed tomography. Surgery for esophageal cancer has a high rate of morbidity and mortality, and it is important to decide on an appropriate treatment method through pre-surgical evaluation. Minimal invasive surgery is widely used for the treatment of gastrointestinal cancer, and endoscopic submucosal dissection is a safe treatment method for early cancer of the gastrointestinal tract that does not result in lymph node metastasis. EUS is essential for pre-surgical evaluation for all esophageal cancers. The use of EUS can effectively reduce unnecessary surgeries and thereby allow for appropriate treatment planning for patients. A number of different diagnostic modalities are available, but EUS is still the mainstay for pre-surgical evaluation of esophageal cancer. The role of EUS for early stomach cancer treatment as a tool for determining the need for endoscopic resection and for pre-surgical assessment is increasing.

Abstract
The preoperative evaluation of oesophageal adenocarcinoma involves endoscopic ultrasound (EUS), computed tomography (CT), and positron emission tomography (PET). With routine Barrett's oesophagus surveillance, superficial cancers are often identified. EUS, CT and PET have a limited role in the staging of superficial tumours. Standard EUS has limited accuracy, but high frequency ultrasound miniprobes are valuable for assessing tumour stage in superficial tumours. However, the best method for determining depth of invasion, and thereby stage of disease, is endoscopic mucosal resection. In contrast, in advanced oesophageal cancers, a multi-modality approach is crucial. Accurate tumour staging is very important since the treatment of advanced cancers involves a combination of chemotherapy, radiation, and surgery. EUS is very useful for staging of the tumour and nodes. High frequency ultrasound miniprobes provide the ability to perform staging when the lesion is obstructing the oesophageal lumen. CT and PET provide valuable information regarding node and metastasis staging.

Abstract
BACKGROUND The advantages of endoscopic ultrasound (EUS) and computed tomography (CT)-positron emission tomography (PET) with respect to survival for esophageal cancer patients are unclear. This study aimed to assess the effects of EUS, CT-PET, and their combination on overall survival with respect to cases not receiving these procedures. METHODS Patients who were ≥66 years old when diagnosed with esophageal cancer were identified in the Surveillance, Epidemiology, and End Results-Medicare linked database. Cases were split into 4 analytic groups: EUS only (n = 318), CT-PET only (n = 853), EUS+CT-PET (n = 189), and no EUS or CT-PET (n = 2439). Survival times were estimated with the Kaplan-Meier method and were compared with the log-rank test for each group versus the no EUS or CT-PET group. Multivariate Cox proportional hazards models were used to compare 1-, 3-, and 5-year survival rates. RESULTS Kaplan-Meier analyses showed that EUS, CT-PET, and EUS+CT-PET patients had improved survival for all stages (with the exception of stage 0 disease) in comparison with patients undergoing no EUS or CT-PET. Receipt of EUS increased the likelihood of receiving endoscopic therapies, esophagectomy, and chemoradiation. Multivariate Cox proportional hazards models showed that receipt of EUS was a significant predictor of improved 1- (hazard ratio [HR], 0.49; 95% confidence interval [CI], 0.39-0.59; P < .0001), 3- (HR, 0.57; 95% CI, 0.48-0.66; P < .0001), and 5-year survival (HR, 0.59; 95% CI, 0.50-0.68). Similar results were noted when the results were stratified on the basis of histology and for the CT-PET and EUS+CT-PET groups. CONCLUSIONS Receipt of either EUS or CT-PET alone in esophageal cancer patients was associated with improved 1-, 3-, and 5-year survival. Future studies should identify barriers to the dissemination of these staging modalities.

Influence of Life Style Factors on Barrett's Oesophagus. Gastroenterol Res Pract 2014; 2014:408470.

Abstract
Background. Since the incidence of adenocarcinoma of the oesophagus is rising, the prognosis is poor, and surveillance programs are expensive and mostly cost ineffective, there is a need to increase the knowledge of risk factors in Barrett's oesophagus and oesophageal cancer in order to be able to give attention to medical prevention and/or surveillance programs. Aim. To study if there is a correlation between the development of Barrett's oesophagus and GOR (gastro oesophageal reflux), family history of GOR, and life style factors, such as alcohol, smoking habits, and mental stress. Methods. Fifty-five consecutively selected patients with Barrett's oesophagus (BO) examined at Linköping University Hospital's Oesophageal Laboratory were matched by sex, age, and duration of reflux symptoms with 55 GOR patients without Barrett's oesophagus at the Oesophageal Laboratory. The medical charts in respective groups were examined for comparison of life style factors, mental stress, medication, duration of gastroesophageal acid reflux at 24 hr-pH-metry, and incidence of antireflux surgery and of adenocarcinoma of the oesophagus (ACO). Also, potential gender differences and diagnosis of ACO were studied. Results. Mean percentage reflux time on 24 hr-pH-metry was higher for the Barrett's oesophagus group, 18% for women and 17% for men compared to 4% for women and 4% for men in the control group (P < 0.05). Family history of GOR was more frequent in Barrett's oesophagus patients (62%) than in the control group (35%) (P < 0.05). Male patients with Barrett's oesophagus had medical therapy for their GOR symptoms to a higher extent (38%) than male controls (65%) (P < 0.05). No difference was found in the number of tobacco users or former tobacco users between Barrett's oesophagus patients and controls. Barrett's oesophagus patients had the same level of alcohol consumption and the same average BMI as the control subjects. Female patients with Barrett's oesophagus rated themselves as more mentally stressed (67%) than the female controls (38%) (P < 0.05). In the five-year medical chart follow-up, five of 55 patients developed adenocarcinoma among the Barrett's oesophagus patients, none in the control group. Conclusions. Long reflux time and family clustering of GOR seem to influence the development of Barrett's oesophagus. Smoking habits, alcohol consumption and BMI do not seem to have any impact on the development of Barrett's oesophagus.

Abstract
Endoscopic ultrasonography (EUS) has gained wide acceptance as an important, minimally invasive diagnostic tool in gastroenterology, pulmonology, visceral surgery and oncology. This review focuses on data regarding risks and complications of non-interventional diagnostic EUS and EUS-guided fine-needle biopsy (EUS-FNB). Measures to improve the safety of EUS und EUS-FNB will be discussed. Due to the specific mechanical properties of echoendoscopes in EUS, there is a low but noteworthy risk of perforation. To minimize this risk, endoscopists should be familiar with the specific features of their equipment and their patients’ specific anatomical situations (e.g., tumor stenosis, diverticula). Most diagnostic EUS complications occur during EUS-FNB. Pain, acute pancreatitis, infection and bleeding are the primary adverse effects, occurring in 1% to 2% of patients. Only a few cases of needle tract seeding and peritoneal dissemination have been reported. The mortality associated with EUS and EUS-FNB is 0.02%. The risks associated with EUS-FNB are affected by endoscopist experience and target lesion. EUS-FNB of cystic lesions is associated with an increased risk of infection and hemorrhage. Peri-interventional antibiotics are recommended to prevent cyst infection. Adequate education and training, as well consideration of contraindications, are essential to minimize the risks of EUS and EUS-FNB. Restricting EUS-FNB only to patients in whom the cytopathological results may be expected to change the course of management is the best way of reducing the number of complications.

Abstract
BACKGROUND The new 7th edition of the Union for International Cancer Control-American Joint Committee on Cancer (UICC-AJCC) tumor, node, metastasis (TNM) staging system is the ratification of data-driven recommendations from the Worldwide Esophageal Cancer Collaboration database. Generalizability remains questionable for single institutions. The present study serves as a validation of the 7th edition of the TNM system in a prospective cohort of patients with predominantly adenocarcinomas from a single institution. METHODS Included were patients who underwent transhiatal esophagectomy with curative intent between 1991 and 2008 for invasive carcinoma of the esophagus or gastroesophageal junction. Excluded were patients who had received neoadjuvant chemo(radio)therapy, patients after a noncurative resection and patients who died in the hospital. Tumors were staged according to both the 6th and the 7th editions of the UICC-AJCC staging systems. Survival was calculated by the Kaplan-Meier method, and multivariate analysis was performed with a Cox regression model. The likelihood ratio chi-square test related to the Cox regression model and the Akaike information criterion were used for measuring goodness of fit. RESULTS A study population of 358 patients was identified. All patients underwent transhiatal esophagectomy for adenocarcinoma. Overall 5-year survival rate was 38%. Univariate analysis revealed that pT stage, pN stage, and pM stage significantly predicted overall survival. Prediction was best for the 7th edition, stratifying for all substages. CONCLUSIONS The application of the 7th UICC-AJCC staging system results in a better prognostic stratification of overall survival compared to the 6th edition. The fact that the 7th edition performs better predominantly in patients with adenocarcinomas who underwent a transhiatal surgical approach, in addition to findings from earlier research in other cohorts, supports its generalizability for different esophageal cancer practices.

Celiac node failure patterns after definitive chemoradiation for esophageal cancer in the modern era. Int J Radiat Oncol Biol Phys 2012; 83:e231-9.

Abstract
PURPOSE The celiac lymph node axis acts as a gateway for metastatic systemic spread. The need for prophylactic celiac nodal coverage in chemoradiation therapy for esophageal cancer is controversial. Given the improved ability to evaluate lymph node status before treatment via positron emission tomography (PET) and endoscopic ultrasound, we hypothesized that prophylactic celiac node irradiation may not be needed for patients with localized esophageal carcinoma. METHODS AND MATERIALS We reviewed the radiation treatment volumes for 131 patients who underwent definitive chemoradiation for esophageal cancer. Patients with celiac lymph node involvement at baseline were excluded. Median radiation dose was 50.4 Gy. The location of all celiac node failures was compared with the radiation treatment plan to determine whether the failures occurred within or outside the radiation treatment field. RESULTS At a median follow-up time of 52.6 months (95% CI 46.1-56.7 months), 6 of 60 patients (10%) without celiac node coverage had celiac nodal failure; in 5 of these patients, the failures represented the first site of recurrence. Of the 71 patients who had celiac coverage, only 5 patients (7%) had celiac region relapse. In multivariate analyses, having a pretreatment-to-post-treatment change in standardized uptake value on PET >52% (odds ratio [OR] 0.198, p = 0.0327) and having failure in the clinical target volume (OR 10.72, p = 0.001) were associated with risk of celiac region relapse. Of those without celiac coverage, the 6 patients that later developed celiac failure had a worse median overall survival time compared with the other 54 patients who did not fail (median overall survival time: 16.5 months vs. 31.5 months, p = 0.041). Acute and late toxicities were similar in both groups. CONCLUSIONS Although celiac lymph node failures occur in approximately 1 of 10 patients, the lack of effective salvage treatments and subsequent low morbidity may justify prophylactic treatment in distal esophageal cancer patients.

Abstract
Endoscopic ultrasonography is a relatively new technology that combines the use of flexible fiberoptic endoscopes with high-resolution ultrasound technology. It proved to be highly accurate and useful in the staging of gastrointestinal malignancies, as well as in characterizing the nature of subepithelial lesions and disorders of the pancreaticobiliary system. In this overview the variety of current evidence based diagnostic options of endoscopic ultrasonography are discussed.

Abstract
The revision of the TNM Classification of Malignant Tumors, 7th Edition, suggests the lymph node (LN) status to be the most significant risk factor in esophageal cancer. This article reviews the current status of LNs as indicators of prognosis. The significance of the number of metastatic LNs, the number of resected LNs, and a novel index, the "LN ratio" (metastatic LNs/removed LNs) in patients with esophageal cancer, were reviewed. The number of metastatic LNs independently predicted the prognosis of both overall survival and relapse-free survival. The number of positive LNs was also the best predictive marker of survival. Furthermore, overall survival significantly depended on the number of surgically removed LNs, and the LN ratio closely correlated with survival. The LN status is considered to be the most significant information that can be used to predict the prognosis. However, there are many issues that still need to be resolved. Better knowledge of the N-status is therefore needed to effectively utilize this information. Further research should focus on the N-status of patients with esophageal cancer.

Abstract
BACKGROUND The combination of endoscopic and laparoscopic ultrasonography (EUS-LUS) is accurate for resectability assessment of patients with upper gastrointestinal cancer (UGIC). But neither the ability of EUS/LUS to predict long-term prognosis nor the potential impact on patient survival using this selection strategy has been investigated. This prospective, single-center study evaluated whether pretherapeutic EUS-LUS stratification related to the prognosis in UGIC patients and whether patient selection by this strategy provided a prognostic outcome comparable with survival data from the literature. METHODS Each patient had a pretherapeutic tumor node metastasis (TNM) stage and a resectability assessment assigned based on EUS-LUS findings. Survival curves were constructed and compared for each of the EUS-LUS TNM stage and resectability groups at the end of the observation period. Finally, the R0 resection rate, median, and 5-year survival rates were compared with the literature. RESULTS This study enrolled 936 consecutive patients with esophageal (n = 256), gastric (n = 273), or pancreatic (n = 407) cancer. A statistically significant survival difference (p < 0.01) between the different TNM stages and resectability groups predicted by EUS-LUS was observed regardless of the cancer type. The poor prognosis for the patients with irresectable or disseminated UGIC was accurately predicted by EUS and LUS. The R0 resection rate as well as the median and 5-year survival rates were comparable with data from the literature. CONCLUSION The pretherapeutic EUS-LUS patient stratification related significantly to the final prognosis for UGIC patients. An EUS-LUS-based patient selection strategy seemed to provide a prognostic outcome similar to data from computed tomography (CT)-based populations.

Abstract
The management of esophageal cancer with involvement of celiac lymph nodes is controversial. The purpose of this retrospective study was to evaluate the clinical importance of metastases to celiac lymph nodes in patients with carcinoma of the distal esophagus or gastroesophageal junction (GEJ) who undergo surgical treatment with curative intent. We reviewed the medical records of 310 patients who underwent definitive esophagectomy at the Mayo Clinic, Rochester, Minnesota, between 1976 and 1999 for carcinoma of the distal esophagus or GEJ. The disease location was distal esophagus in 163 and GEJ in 147. Fifty-two patients (17%) were found to have celiac node involvement. The survival of these patients was compared with that of 97 N0 patients and 161 N1 patients without celiac node involvement. Squamous cell carcinoma and adenocarcinomas were found in 24% and 76%, respectively. Ivor Lewis esophagectomy was the most common surgical procedure (76%), followed by transhiatal resection (14%) and modified Ivor Lewis procedure (5%). The median number of nodes resected was 15 (range, 2-45). The median survival of the entire group was 18.8 months. The median survival was 48 months (range, 1.6 months-22 years) for N0 patients and 15.9 months (range, 0.03 months-14.4 years) for N1 patients without celiac node disease (P < 0.001). The median survival was 11.7 months (range, 2.2 months-15.7 years) for celiac node-positive patients, and this difference was statistically significant when compared with survival in N0 patients (P= 0.001) but not when compared with that in N1 patients without celiac node disease (P= 0.57). Survival at 3 and 5 years was 61% and 45% for N0 patients, 21% and 9% for N1 patients without celiac node disease, and 18% and 11% for patients with celiac node disease, respectively. At 10 years, 7% of patients with celiac node involvement in their resected specimen were alive. By multivariate analysis, patients with 4 or more positive lymph nodes had the worst prognosis (risk ratio [RR], 2.63; 95% confidence interval [CI], 1.98-3.48), regardless of their location. We concluded that celiac node metastases were not an adverse prognostic indicator in patients with celiac node involvement compared with N1 patients without celiac node disease. Overall, the number of positive nodes, not their location, correlated best with survival. Although median survival was poor, a small number of patients with resected celiac node disease had long-term survival. Patients with undetected celiac node disease at the time of surgical resection who were subsequently found to have celiac node involvement appeared to have a prognosis similar to that of patients with stage III disease. Therefore, treatment with curative intent should be considered for fit patients with celiac node disease.

Abstract
BACKGROUND The expected survival after the EUS-FNA diagnosis of malignant ascites or liver metastases from pancreatic cancer is not known. OBJECTIVE To report overall and 1-year survival in these patients. DESIGN Retrospective cohort series. SETTING Tertiary referral hospital. PATIENTS Consecutive subjects with newly diagnosed pancreatic cancer from June 1998 and March 2008 in whom EUS-FNA of the liver or ascitic fluid confirmed hepatic metastases or malignant ascites. INTERVENTIONS Calculation of survival after diagnosis by using the Social Security Death Index. MAIN OUTCOME MEASUREMENTS Survival after EUS-FNA diagnosis of stage IV pancreatic cancer. RESULTS EUS-FNA identified liver metastases and malignant ascites from primary pancreatic cancer in 75 and 13 patients, respectively, and all 88 died during follow-up. For all 88 patients, the 1-year survival rate and median survival were 3.4% (95% CI, 1.1%-10.4%) and 82 days (range 2-754 days), respectively. The 1-year survival rates for those with liver metastases (4.0% [95% CI, 1.3%-12.1%]) and for those with malignant ascites (0% [95% CI, 0-24.7%]) were similar (P = 1.0). The median survival for patients with liver metastases of 83 days (range 2-754 days) was similar to that for those with malignant ascites (64 days; range 2-153 days) (P = .13). No clinical variable considered predicted survival of more than, less than, or 3 months. LIMITATIONS Retrospective series with variable treatment for malignancy. CONCLUSIONS In patients with pancreatic cancer, identification of malignant ascites or liver metastases by EUS-FNA is associated with a very poor prognosis.

Abstract
Numerous studies conducted over the last 25 years provide evidence on the high diagnostic accuracy and important role of endoscopic ultrasonography (EUS) in staging oesophageal and gastric carcinoma. This extensive research was recently subjected to metaanalyses, condensing our knowledge on EUS performance and facilitating its comparison with competing methods. It is, however, important to realise that the management of oesophageal and gastric carcinoma is evolving and so are staging algorithms, setting new challenges for EUS and re-defining its position. Restaging after neoadjuvant treatment and precise assessment of early carcinoma before endoscopic treatment are areas of growing interest, but the role of EUS in these settings is rather limited. Rapidly developing cross-sectional imaging has the potential to challenge the position of EUS as the most accurate method in loco-regional staging. On the other hand, EUS guided fine-needle aspiration offers the unique opportunity to obtain cytological confirmation of lymph node metastases, with future potential for molecular staging.

Abstract
Esophageal cancer is a leading cause of cancer mortality worldwide. Complete resection of esophageal cancer and adjacent malignant lymph nodes is the only potentially curative treatment. Accurate preoperative staging and assessment of therapeutic response after neoadjuvant therapy are crucial in determining the most suitable therapy and avoiding inappropriate attempts at curative surgery. Computed tomography (CT) is recommended for initial imaging following confirmation of malignancy at pathologic analysis, primarily to rule out unresectable or distant metastatic disease. With the advent of multidetector CT, use of thin sections and multiplanar reformation allows more accurate staging of esophageal cancer. Endoscopic ultrasonography (US) is the best modality for determining the depth of tumor invasion and presence of regional lymph node involvement. Combined use of fine-needle aspiration and endoscopic US can improve assessment of lymph node involvement. Positron emission tomography (PET) is useful for assessment of distant metastases but is not appropriate for detecting and staging primary tumors. PET may also be helpful in restaging after neoadjuvant therapy, since it allows identification of early response to treatment and detection of interval distant metastases. Each imaging modality has its advantages and disadvantages; therefore, CT, endoscopic US, and PET should be considered complementary modalities for preoperative staging and therapeutic monitoring of patients with esophageal cancer.

Abstract
Data from the USA suggest that morphological specificity is insufficient to permit an assumption of malignancy in nodal staging with endoscopic ultrasound (EUS). This may not hold true elsewhere as the background lymph node burden may vary in different geographic regions. We aimed to assess the prevalence and features of mediastinal and abdominal lymph nodes at EUS in a Northern European population without malignant disease. A total of 129 consecutive patients without malignant disease referred for radial EUS were prospectively evaluated for the prevalence and echo features of lymph nodes in the mediastinum and upper abdomen. Sixty-two percent of patients had mediastinal lymph nodes and 17% had abdominal nodes at EUS. A mean of 1.4 (standard deviation 1.3, range 0-8) nodes were found per patient. No celiac nodes were seen. The majority of detected nodes were 0.5 cm or less in short axis, had oval shape, centrally echogenic pattern, and indistinct borders. The most common node locations were the subcarinal and paraesophageal areas, and the hepatoduodenal ligament. In multivariate analysis mediastinal lymphadenopathy was related to body mass index and abdominal lymphadenopathy to acute pancreatitis. The occurence of mediastinal lymphadenopathy is markedly lower in Northern Europeans than reported for US patients. Celiac nodes are extremely rare in patients without malignancy. The majority of nodes have a width of 0.5 cm or less, have oval shape, centrally echogenic pattern, and indistinct borders. The characterization of the background lymph node burden may improve the selection of lymph nodes for fine needle aspiration.

Abstract
Accurate staging of esophageal cancer is critical to achieving optimal treatment outcomes. End-oscopic ultrasound with fine needle aspiration (EUS-FNA) has emerged as a valuable tool for locoregional staging. However, it is unclear how different physician specialties perceive the benefit of EUS-FNA for esophageal cancer staging, and thus utilize this modality in clinical practice. A survey regarding utilization of EUS-FNA in esophageal cancer was distributed to 211 thoracic surgeons and 251 EUS-capable gastroenterologists. Seventy-six thoracic surgeons (36%) and 78 gastroenterologists (31%) responded to the survey. Most surgeons (75%) use EUS to stage potentially resectable esophageal cancer 75% of the time. Surgeons using EUS less often are less likely to have access to high-quality EUS services than their peers. Fewer surgeons believe EUS is the most accurate test for T and N-staging (84% and 71%, respectively) as compared with gastroenterologists (97% and 96%, P < 0.01 for both). Most endosonographers (68%) decide whether to dilate a malignant esophageal stricture to complete the staging exam on a case-by-case basis. Surgeons disagree as to whether involvement of celiac lymph nodes should preclude esophagectomy in distal esophageal cancer. While most thoracic surgeons have embraced EUS-FNA as the most accurate locoregional staging modality in esophageal cancer, this attitude is not fully reflected in utilization patterns due to a lack of quality EUS services in some centers. Controversial areas that warrant further study include dilation of malignant strictures to facilitate EUS staging, and the implication of involved celiac lymph nodes on management.

Abstract
BACKGROUND Published data on the accuracy of endoscopic ultrasound (EUS) for staging distant and celiac axis lymph node (CLN) metastasis in patients with esophageal cancer (ECA) has varied. AIM To evaluate the accuracy of EUS in diagnosing distal and CLN metastasis in ECA patients. STUDY SELECTION EUS studies confirmed by surgery were selected. STATISTICAL METHOD Pooling was conducted by both fixed and random-effects models. RESULTS Data were extracted from 25 studies (N = 2029) which met the inclusion criteria. In ECA patients, pooled sensitivity of EUS was 67.2% (95% CI: 62.6-71.6) in diagnosis of distal metastasis and 66.6% (95% CI: 61.9-71.1) in diagnosis of CLN metastasis. EUS had a pooled specificity of 97.9% (95% CI: 97.1-98.6) for distal metastasis and 98.1% (95% CI: 97.3-98.7) for CLN metastasis. CONCLUSIONS Although EUS has excellent specificity in accurately diagnosing distal and CLN metastasis in patients with ECA, the sensitivity is low.

Abstract
Involvement of celiac nodes is defined as distant metastasis in the TNM classification for thoracic esophageal carcinoma. Some textbooks, however, describe dissection of these nodes as a standard technique. The present study was, therefore, undertaken to clarify which celiac nodes are regional for thoracic esophageal carcinoma and whether or not celiac node dissection would provide a survival benefit. Eight hundred and five patients who underwent R0 resection (no residual tumor) with systematic lymphadenectomy including the celiac axis area for thoracic esophageal carcinoma were retrospectively investigated. The frequency of metastasis and the therapeutic value of dissecting celiac nodes were compared to those associated with the left gastric artery area. The frequencies of left gastric and celiac nodal involvement were 15.4% and 9.6%, respectively, for thoracic esophageal carcinoma. As for tumor location, the incidences of metastasis around left gastric artery and celiac axis from the upper, middle and lower portion were 6.7% and 1.0%; 12.3% and 7.7%; and 25.7% and 17.4%, respectively. The 5-year survivals of patients with celiac but not left gastric metastasis were 36.3% and 41.8% for the middle and lower portions, respectively, while the corresponding values with left gastric involvement but no celiac metastasis were 24.1% and 27.9%. These differences were not significant. The frequency of celiac node involvement was not low. And, their dissection has equivalent therapeutic value to that of left gastric nodes. Revision of the TNM classification to account for celiac node involvement in thoracic esophageal carcinoma, especially of the middle and lower portions, is needed.

Abstract
Metastasis is the principal cause of cancer mortality, with the lymphatic system being the first route of tumor dissemination. The glycoproteins VEGF-C and VEGF-D are members of the vascular endothelial growth factor (VEGF) family, whose role has been recently recognized as lymphatic system regulators during embryogenesis and in pathological processes such as inflammation, lymphatic system disorders and malignant tumor metastasis. They are ligands for the VEGFR-3 receptor on the membrane of the lymphatic endothelial cell, resulting in dilatation of existing lymphatic vessels as well as in vegetation of new ones (lymphangiogenesis). Their determination is feasible in the circulating blood by immunoabsorption and in the tissue specimen by immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR). Experimental and clinicopathological studies have linked the VEGF-C, VEGF-D/VEGFR3 axis to lymphatic spread as well as to the clinical outcome in several human solid tumors. The majority of these data are derived from surgical specimens and malignant cell series, rendering their clinical application questionable, due to subjectivity factors and post-treatment quantification. In an effort to overcome these drawbacks, an alternative method of immunodetection of the circulating levels of these molecules has been used in studies on gastric, esophageal and colorectal cancer. Their results denote that quantification of VEGF-C and VEGF-D in blood samples could serve as lymph node metastasis predictive biomarkers and contribute to preoperative staging of gastrointestinal malignancies.

Abstract
OBJECTIVES Although endoscopic ultrasound (EUS) staging of esophageal cancer is established in clinical practice, high-quality evidence about its impact on patient outcomes is not available. This study aims to determine the impact of EUS for esophageal cancer staging on patient management and survival. METHODS A systematic review was conducted using Medline, PreMedline, Embase, and The Cochrane Library. Included studies were (i) comparative studies reporting survival following EUS esophageal cancer staging, (ii) therapeutic impact studies reporting change in patient management following EUS. The quality of included studies was critically appraised. RESULTS One systematic review, five studies reporting therapeutic impact, and two studies reporting patient survival were identified. The design and quality of the therapeutic impact studies varied widely. Management changed in 24-29 percent of patients following EUS staging of esophageal cancer (two studies). No studies provided data on the avoidance of surgery for this indication. One retrospective cohort study with historical control found EUS staging of esophageal cancer improved patient survival; a second study with similar design limitations did not find a survival benefit for EUS staging in patients undergoing resection. These studies had a high potential for bias, limiting the value of these findings. CONCLUSIONS Two studies provided evidence of a change in patient management following EUS for staging esophageal cancer, a higher level of evidence for a clinical benefit than can be obtained from accuracy studies alone. This evidence contributed to a recommendation for public funding of EUS in staging esophageal cancer in Australia.

Abstract
Positron emission tomography (PET)/computed tomography (CT) has important utility and limitations in the initial staging of esophageal cancer, evaluation of response to neoadjuvant therapy, and detection of recurrent malignancy. Esophageal cancer is often treated by using a combined modality approach (chemotherapy, radiation therapy, and esophagectomy); correct integration of PET/CT into the conventional work-up of esophageal cancer requires a multidisciplinary approach that combines the information from PET/CT with results of clinical assessment, diagnostic CT, endoscopic gastroduodenoscopy, and endoscopic ultrasonography. PET/CT has limited utility in T staging of esophageal cancer and relatively limited utility in detection of dissemination to locoregional lymph nodes. However, PET/CT allows detection of metastatic disease that may not be identifiable with other methods. PET/CT is not sufficiently reliable in the individual patient for determination of treatment response in the primary tumor. Interpretation of PET/CT results is optimized by understanding the diagnostic limitations and pitfalls that may be encountered, together with knowledge of the natural history of esophageal cancer and the staging and treatment options available.

Abstract
Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) may be employed for procurement of a tissue diagnosis in a minimally invasive fashion. In many cases, EUS-FNA excludes the need for more invasive diagnostic procedures when a tissue diagnosis is required. In patients with esophageal neoplasms, EUS-FNA is a safe and accurate tool for the preoperative diagnosis of metastatic spread to the paraesophageal and celiac lymph nodes. EUS-FNA is also increasingly recognized as an accurate, cost-effective and safe means of evaluating and staging patients with lung cancer. EUS-FNA is useful in providing tissue confirmation of cancer in cases in which bronchoscopy or computed tomography-guided approaches has been non-diagnostic. EUS-guided therapies are paving the way for therapeutic/interventional EUS. The interventional endoscopist will now play a more central role in the diagnosis and treatment of various gastrointestinal malignancies by delivering antitumor agents.

Abstract
BACKGROUND The current American Joint Committee on Cancer (AJCC) esophageal cancer staging for nodal status is difficult to interpret and is based solely on lymph node location relative to the primary tumor's esophageal location. Recent reports suggest that the number of lymph nodes involved is also an important factor. We reviewed our esophageal experience to propose an improved nodal staging system. METHODS In all, 1,027 patients with resected esophageal cancer from 1970 to 2005 were reviewed. Lymph nodes stations were assigned according to AJCC criteria. Overall survival was assessed by Kaplan-Meier analysis. The impact of location, number of involved lymph nodes, and use of preoperative chemotherapy or radiation therapy, or both, was assessed. RESULTS Nonregional nodal involvement (n = 17) was associated with decreased survival compared with regional (n = 441) or celiac nodal (n = 73) involvement (3-year: 0% versus 24% and 23%; p < 0.001). The number of involved lymph nodes was strongly associated with survival (3-year: 0 nodes = 63%, 1 to 3 nodes = 31%, more than 3 nodes = 13%; p < 0.001), and multivariable Cox proportional-hazards analysis suggested that the location and number of involved lymph nodes were independent predictors of survival (p < 0.001). We propose a modified nodal staging system that designates celiac nodes as regional and includes number of involved nodes: pN0, no nodes (3 years = 63%, n = 496); pN1-regional, 1 to 3 nodes (3 years = 32%, n = 292); pN2-regional, more than 3 nodes (3 years = 14%, n = 222); pN3-nonregional node (3 years = 0%, n = 17 [p < 0.0001]). This modified nodal staging system better predicts survival than the current AJCC nodal staging system in which survival for pN1 (3 years = 24%) and pM1a (3 years = 23%) do not differ (p = 0.67). The use of induction before surgical resection did not alter the predictive effect of the new nodal staging system. CONCLUSIONS Modification of the AJCC nodal classification system to incorporate the number of involved lymph nodes with regional and nonregional node location simplifies and better predicts long-term survival than does the current AJCC nodal system.

Abstract
BACKGROUND Rapid and accurate tissue diagnosis for a deep-seated malignancy would allow treating physicians to provide disease-specific interventions and help patients make early informed management decisions. Providing on-site tissue diagnosis for fine-needle aspirate samples obtained with endosonography would help develop such efficient patient management issues. Here we report our experience of prospectively providing on-site diagnosis on 485 endoscopic ultrasound fine-needle aspirate samples. METHODS Four hundred eighty-five endoscopic ultrasound fine-needle aspirates from the pancreas (n= 305), lymph nodes (n = 91), biliary tree (n = 47), liver (n = 15), gastrointestinal tract (n = 19), and adrenal gland (n = 8) were reviewed. For all aspirates, the cytologic diagnoses, both preliminary and final, were categorized into the following: positive for malignancy, positive for neoplastic process, suspicious for malignancy, atypical cells, reactive process, and nondiagnostic. RESULTS Of the 485 cases, 163 (33.6%) were diagnosed as benign, 43 (8.8%) as atypical, 21 (4.3%) as suspicious, 18 (3.7%) as positive for neoplasm, and 230 (47.4%) as malignant after final cytologic interpretation. A significantly (P < .001) higher degree of concordance was noted for unequivocal diagnosis of malignancy (196/198, 98.9%) vs nonmalignancy (200/250, 67.2%) between on-site and final cytologic diagnosis. Of the 52 discordant cases, 12 (2.6%) diagnoses were downgraded and 40 (8.9%) were upgraded from preliminary on-site diagnosis. Our overall sensitivity (87 vs 92), specificity (95% vs 100%), and accuracy (90% vs 94%) improved for final cytologic diagnosis. CONCLUSION On-site diagnosis of malignancy could be used to initiate informed patient management decisions. Cases where a diagnosis of malignancy is not rendered at on-site interpretation need further cytologic evaluation.

Abstract
Cancer of the esophagus continues to be a threat to public health. The common practice is esophagectomy for surgically resectable tumors and radiochemotherapy for locally advanced, unresectable tumors. However, local regional tumor control and overall survival of esophageal cancer patients after the standard therapies remain poor, approximately 30% of patients treated with surgery only will develop local recurrence, and 50% to 60% patients treated with radiochemotherapy only fail local regionally due to persistent disease or local recurrence. Esophagectomy after radiochemotherapy or preoperative radiochemotherapy has increased the complete surgical resection rate and local regional control without a significant survival benefit. Induction chemotherapy followed by preoperative radiochemotherapy has produced encouraging results. In addition to patient-, tumor-, and treatment-related factors, involvement of celiac axis nodes, number of positive lymph nodes after preoperative radiochemotherapy, incomplete pathologic response, high metabolic activity on positron emission tomography scan after radiochemotherapy, and incomplete surgical resection are factors associated with a poor outcome. Radiochemotherapy followed by surgery is associated with significant adverse effects, including treatment-related pneumonitis, postoperative pulmonary complications, esophagitis and pericarditis. The incidence and severity of the adverse effects are associated with chemotherapy and radiotherapy dosimetric factors. Innovative treatment strategies including physically and biologically molecular targeted therapy is needed to improve the treatment outcome of patients with esophageal cancer.

Abstract
BACKGROUND & AIMS The aim of this study is to report a large single-center experience with endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) of ascites. METHODS Consecutive patients at our institution in whom EUS-guided paracentesis was performed between January 1997 and July 2005 were identified retrospectively. All procedures were performed by or under the supervision of 1 of 5 experienced endosonographers with available on-site cytopathology. RESULTS Sixty consecutive patients (33 men; mean age, 67 y) were identified. Previously attempted percutaneous paracentesis was unsuccessful in 3 of 6 patients. Ascites confirmed by EUS FNA was visible in 28 of 54 (52%) computerized tomography, 3 of 11 (27%) transabdominal ultrasound, and 4 of 8 (50%) magnetic resonance imaging examinations before EUS. Transgastric (n = 55) or transduodenal (n = 5) EUS-guided paracentesis (mean, 8.9; range, 1-40 mL) revealed malignancy in 16 (27%) from primary pancreatic (n = 9), gastric (n = 2), urothelial (n = 1), esophageal (n = 1), gallbladder (n = 1), bile duct (n = 1) cancer, and lymphoma (n = 1). The cytology from 2 patients was atypical (1 suspicious for malignancy and 1 considered reactive) and the remaining 42 were benign. Potential complications occurred in 2 of 60 (3%) patients with self-limited fever. Of the 8 of 60 (13%) patients who underwent subsequent surgery, 3 had metastatic pancreatic adenocarcinoma (n = 2) and metastatic small intestinal carcinoid (n = 1) to the peritoneum after negative EUS-FNA cytology. CONCLUSIONS EUS frequently identifies ascites missed by other imaging studies. EUS-guided paracentesis may identify malignancy in a subset of patients. Negative ascitic fluid cytology from EUS FNA does not exclude possible peritoneal carcinomatosis.

Abstract
Computed tomography (CT) and endoscopy/endoscopic ultrasonography are usually performed to initially stage patients with esophageal cancer, to determine primary tumor response, and to detect nodal and distant metastases after preoperative therapy. Positron-emission tomography (PET) with [18F]-fluoro-2-deoxy-D-glucose and integrated CT-PET are useful in the initial staging of patients with esophageal cancer as well as in the prediction of pathologic response, disease-free interval, and overall survival after preoperative therapy. Importantly, integrated CT-PET imaging decreases the number of futile attempts at surgical resection, mainly because of the detection of occult distant metastases. The following sections review the use of integrated CT-PET imaging in determining the T, N, and M descriptors of the American Joint Commission on Cancer's 2002 guidelines for pathologic and clinical staging at initial diagnosis and after chemoradiation therapy in those patients being considered for surgical resection.

Abstract
Dilation of malignant esophageal strictures often is required to complete staging by endoscopic ultrasound (EUS). This study was designed to determine the successful dilation rate (ability to complete staging) and complication rate of through-the-scope (TTS) balloon dilation for malignant esophageal strictures during EUS. We retrospectively reviewed EUS reports for all cases of primary esophageal cancer staged at five centers between January 2002 and October 2004. All dilations were performed with TTS balloons. Among 272 endoscopic ultrasounds, dilation was required in 77 (28%) and was successful in 73 cases (95%). There was one esophageal perforation after dilation (1.3%; 95% confidence interval (CI), 0.2-7) and one esophageal perforation after EUS without dilation (0.5%; 95% CI, 0.1-2.8; P = 0.48 by two-sided Fisher exact test). There were no other major complications. TTS balloon dilation is highly successful in permitting complete staging of obstructing tumors. The rate of complications after dilation with a TTS balloon dilator is low and similar to the baseline rate of EUS in this setting.

Abstract
OBJECTIVE The American Joint Committee on Cancer (AJCC) staging system for esophageal cancer is controversial because it relies on arbitrary definitions of the anatomic location of lymph nodes to establish N and M status. It has been proposed that the number of involved lymph nodes may better predict survival. We reviewed our experience to determine the prognostic impact of the number of involved nodes and the extent of lymphadenectomy on the current staging system. METHODS Records of all patients who underwent resection of previously untreated adenocarcinoma and squamous cell carcinoma of the esophagus and gastroesophageal junction were reviewed. Overall survival according to the AJCC staging system and the number of involved lymph nodes was analyzed by the method of Kaplan and Meier and by recursive partitioning methods. RESULTS Data were available on 336 patients operated on between January 1996 and September 2003. Recursive partitioning analysis using AJCC staging variables reproduced the AJCC staging system. When the number of involved lymph nodes is added, patients with more than 4 involved lymph nodes have survival similar to that of patients with M1 disease, and patients with no involved lymph nodes have the best prognosis. Recursive partitioning analysis identified 18 lymph nodes as the minimal number required for accurate staging. In patients who have 18 or more lymph nodes removed, survival is only predicted by the presence of nodal involvement and M1 disease. CONCLUSION Our analysis suggests that revisions of the current AJCC staging system for esophageal cancer should include N staging based on the number of involved lymph nodes and minimal requirements for the extent of lymphadenectomy.

Abstract
Combining different treatment modalities--such as surgery, radiation, and chemotherapy--is often utilized to treat patients with locally advanced esophageal cancer. However, it remains controversial how best to combine these modalities to provide patients with the greatest chance of cure. This review discusses recent studies in this field and outlines promising versus less promising therapeutic strategies.

Abstract
BACKGROUND AND AIM An inverse correlation between hospital volume and esophageal resection mortality has been reported. In this study, we compared the quality of preoperative metastasis detection between a high-volume referral center with that of low-volume referring regional centers. METHODS In 573 patients diagnosed with esophageal cancer (1994-2003), the results of preoperative staging investigations (CT-scan, ultrasound of abdomen and neck, and chest x-ray) performed in 61 regional centers were re-evaluated and/or repeated in one referral center. The gold standards were a radiological result with > or =6 months follow-up, fine-needle aspiration, or the postoperative TNM-stage. RESULTS In the same group of patients, the preoperative investigations performed in regional centers detected true-positive malignant lymph nodes in 8% of patients and true-positive distant metastases in 7% of patients, whereas these percentages were 16% and 20%, respectively, in the referral center. In 72/573 (13%) patients, one or more metastases detected in the referral center had been missed in the regional centers. After allowing resectability in the presence of M1a lymph nodes, this would still have resulted in futile esophageal resections in 6% of patients. In contrast to the higher diagnostic sensitivity in the referral center, specificity was comparable between referral and regional centers. CONCLUSIONS This study found that, in assessing the operability of esophageal cancer, the diagnostic sensitivity of metastasis detection in a high-volume referral center was higher than that in referring regional centers. This resulted from both better CT-scanning equipment and more experienced radiologists in the referral center. Should the decision to perform esophagectomy have only been based on metastasis detection in these regional centers, over 1 in 20 patients would have undergone resection in the presence of metastases.

Abstract
OBJECTIVE We reviewed our experience with preoperative chemoradiotherapy in patients with adenocarcinoma of the distal esophagus and pretreatment endoscopic ultrasonography-identified celiac adenopathy. METHODS One hundred eighty-six patients with adenocarcinoma of the distal esophagus were staged with endoscopic ultrasonography before treatment from 1997 through 2004. All patients were treated with concurrent chemoradiotherapy (CRT group) and surgical intervention or induction chemotherapy followed by concurrent chemoradiotherapy (C-->CRT group) and surgical intervention. Survival analysis (excluding operative mortality) evaluated various pretreatment factors. RESULTS Multivariable Cox regression analysis showed that pretreatment endoscopic ultrasonography-identified celiac adenopathy was a significant predictor of decreased long-term survival (P = .03). Median and 3-year survivals were 49 months and 54% in the endoscopic ultrasonography-identified cN0 M0 group (n = 65), 45 months and 56% in the endoscopic ultrasonography-identified cN1 M0 group (n = 96), and 19 months and 12% in the endoscopic ultrasonography-identified celiac adenopathy (cM1a) group (n = 18; P = .03). Increased systemic relapse was noted in the endoscopic ultrasonography-identified cM1a group (44% vs 22%, P = .07). The only factor associated with increased survival in the endoscopic ultrasonography-identified cM1a group (27 vs 15 months, P = .02) was the addition of induction chemotherapy before concurrent chemoradiotherapy and surgical intervention. CONCLUSIONS Endoscopic ultrasonography-identified celiac adenopathy in patients with adenocarcinoma of the distal esophagus conveys a poor prognosis despite preoperative chemoradiotherapy. These patients should be stratified in future multimodality trials. The investigation of induction chemotherapy before concurrent chemoradiotherapy might be warranted in this high-risk group of patients.

Abstract
AIM: To investigate the effect of double staining, methylene blue and Lugol's solution, combined with endosonography in the detection of early cancer and precancerous lesions of esophagus.
METHODS: Ninety-six patients with doubtful esophageal diseases were involved in this study. The lesions were firstly treated with methylene blue (20 g/L) and then Lugol's solution (30 g/L). Biopsies were performed in the parts stained by methylene blue but unstained by Lugol's solution. Endosonography was also performed in the patients diagnosed with esophageal cancer, severe atypical hyperplasia, and Barrett's esophagus.
RESULTS: Seven patients with esophagus cancer (including 2 cases of early cancer), 14 with atypical hyperplasia (7 light, 4 moderate, 3 severe), 3 with Barrett's esophagus, 8 with ulcer and 36 with inflammation. The total positive rate of double staining is 70.8%. The accuracy rate of endosonography is 92.3% (12/13) in detecting the infiltration depth and the mediastinal lymph node metastasis of early esophageal cancer and precancerous lesions.
CONCLUSION: The double staining of methylene blue and Lugol's solution combined with endosonography is helpful in the diagnosis of esophageal diseases, especially the early cancer and precancerous lesions.

Abstract
PURPOSE Despite the increasing number of publications concerning (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) for staging of esophageal cancer and the increasing availability of this novel diagnostic modality, its exact role in preoperative staging of these tumors is still unknown. The aim of this study was to systematically review the literature regarding the diagnostic performance of FDG-PET in preoperative staging of patients with esophageal cancer, and to calculate summary estimates of its sensitivity and specificity. METHODS The databases of PubMed, Embase, and Cochrane were searched for relevant studies. Two reviewers independently assessed the methodological quality of each study. A meta-analysis of the reported sensitivity and specificity of each study was performed. RESULTS Twelve studies met the inclusion criteria. The studies had several design deficiencies. Pooled sensitivity and specificity for the detection of locoregional metastases were 0.51 (95% CI, 0.34 to 0.69) and 0.84 (95% CI, 0.76 to 0.91), respectively. For distant metastases, pooled sensitivity and specificity were 0.67 (95% CI, 0.58 to 0.76) and 0.97 (95% CI, 0.90 to 1.0), respectively. CONCLUSION FDG-PET showed moderate sensitivity and specificity for the detection of locoregional metastases, and reasonable sensitivity and specificity in detection of distant lymphatic and hematogenous metastases.
