Should the clinical significance of supraclavicular and celiac lymph node metastasis in thoracic esophageal cancer be reevaluated? Thorac Cancer 2019; 10:1725-1735. [PMID: 31293066 PMCID: PMC6669804 DOI: 10.1111/1759-7714.13144] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2019] [Revised: 06/22/2019] [Accepted: 06/23/2019] [Indexed: 12/17/2022] Open
Abstract
Background Lower thoracic esophageal cancer (LTEC) with celiac node metastasis and upper thoracic esophageal cancer (UTEC) with supraclavicular node metastasis were previously categorized as M1a diseases. Our study aimed to investigate whether the clinical significance of supraclavicular and celiac lymph node metastasis should be reevaluated in thoracic esophageal cancer. Methods A total of 6178 patients with thoracic esophageal cancer were identified from the Surveillance, Epidemiology, and End Results (SEER) database during 2004–2015. Treatment strategies and outcomes (OS, overall survival; CSS, cancer‐specific survival) of patients with different nodal status were reviewed. The Cox proportional hazards regression model was applied to evaluate the prognostic factors. Statistical analyses were performed in all subgroups. Results Multivariate analysis identified supraclavicular node metastasis but not celiac node metastasis as an independent predictor of both OS and CSS in LTEC. However, metastasis to supraclavicular or celiac nodes was not an independent predictor of OS and CSS in UTEC. Surgery was not associated with increased OS and CSS for UTEC with celiac or supraclavicular node metastasis but was favored as a predictor of better OS and CSS for LTEC with celiac or supraclavicular node metastasis. Radiotherapy benefited OS and CSS in LTEC involving celiac or supraclavicular nodes and in UTEC involving celiac nodes, while only OS benefited from radiotherapy in UTEC involving supraclavicular nodes. Conclusions These results provide preliminary evidence that the clinical significance of supraclavicular and celiac lymph node metastasis should be reevaluated in thoracic esophageal cancer with different prognostic information according to the primary sites.

Abstract
PURPOSE To determine the prognostic significance of unilateral cervical lymph nodal metastasis (CLNM) in patients with inoperable thoracic esophageal squamous cell carcinoma (SCC) and to identify significant prognostic factors in these patients. PATIENTS AND METHODS This retrospective study involved 395 patients with inoperable esophageal SCC treated with concurrent chemoradiotherapy. The patients were classified into three groups according to their cervical lymph node status: group A, no evidence of CLNM; group B, unilateral CLNM; group C, other distant metastases. Overall survival (OS) and progression-free survival (PFS) were calculated. Significant prognostic factors were identified using univariate and multivariate analyses. RESULTS The 3-year OS rates in groups A, B and C were 46.7%, 33.5% and 8.3%, respectively (p<0.001, log-rank test). The corresponding PFS rates were 40.7%, 26.4% and 4.7% (p<0.001, log-rank test). Group B had a similar prognosis to that of group A and better 3-year OS (p = 0.009) and PFS (p = 0.006) rates than those of group C. Multivariate analysis demonstrated that T stage, chemotherapy regimen and cervical lymph node involvement were independent prognostic factors affecting OS and PFS. CONCLUSIONS Compared to other distant metastases, unilateral CLNM is associated with longer OS in esophageal SCC and should be regarded as a regional disease. Sex, T stage, concurrent chemotherapy modality and cervical lymph node involvement are independent predictors of survival in esophageal SCC.

Abstract
OBJECTIVE Endoscopic ultrasound (EUS) is established as the most accurate technique for pre-operative locoregional staging of gastroesophageal junction (GEJ) adenocarcinoma, the purpose of the present study was to evaluate the distant lymph nodes (LNs) EUS-fine-needle aspiration (FNA) impact in therapeutic decision for patients with GEJ adenocarcinoma. MATERIALS AND METHODS Retrospective study was made, with cross-sectional, non-probabilistic analysis from prospectively collected database for all GEJ adenocarcinoma staging patients referred between January 2009 and August 2012 in Paoli-Calmette Institute in Marseille-France. RESULTS A total of 154 patients with GEJ adenocarcinoma were managed in our institution, of whom 113 (73.3%) had non-distant metastatic disease at computed tomography (CT) scan and underwent EUS for initial tumor staging prior to a treatment decision. On A total of 113 patients undergoing EUS, 8 (7%) patients underwent endoscopic resection and 6 (5.3%) underwent direct surgical resection. Of the remaining 99 patients (87.6%), 24 (21.2%) distant LN EUS-FNA were made. Seventeen LN had EUS malignant features, including 9 (52.9%) that were confirmed as malignant and underwent palliative treatment with chemotherapy. Ninety (79.6%) patients were treated with pre-operative neoadjuvant therapy and were revaluated after. 4 (4.4%) had metastatic disease at CT scan (underwent palliative treatment) and 65 (72.2%) underwent EUS restaging to treatment decision revaluation. Of these, twelve (18.4%) distant LN EUS-FNA were performed. Seven had LN EUS malignancy features, including 4 (57.1%) that were confirmed as malignant and underwent palliative treatment. The remaining 61 patients underwent surgery. As stated above, 21 patients (23.3%) did not undergo EUS restaging, including 10 (47.6%) that did not go to surgery because patient's age, poor general status and comorbidities, 6 (28.5%) had a loss of follow-up, 1 (4.7%) underwent to surgery due to chemotherapy collateral effects, 3 (14.2%) were still on pre-operative chemotherapy and 1 (4.7%) died for sepsis after mediastinal EUS-FNA, this was the only complication event evidenced. EUS-FNA changed clinical management in 54.2% of patients who met the criteria inclusion (distant LN with malignancies EUS features), which corresponds to 11.5% of patients with GEJ adenocarcinoma. CONCLUSION EUS-FNA was able to provide a different tumor staging and these differences were associated with treatment received. EUS-FNA had a significant impact on treatment decision.

Abstract
BACKGROUND Currently, the most accurate staging test for patients with esophageal cancer is endoscopic ultrasound (EUS). At many institutions, patients who have completed neoadjuvant chemotherapy and radiotherapy for esophageal cancer undergo restaging EUS before proceeding to surgical resection. The benefit of this restaging procedure remains controversial. METHODS We retrospectively studied consecutive patients who had pre-resection restaging EUS after receiving neoadjuvant treatment to assess accuracy of EUS restaging and determine whether it predicted survival. RESULTS Final pathologic data were available for 73 patients who underwent restaging EUS (3 patients had missing T or N stage at one time point). Median time from restaging EUS to resection was 20 days. Restaging EUS accurately predicted pathologic T status in 26 of 72 patients (36%), N status in 44 of 71 (62%), and detected a complete pathologic response in 2 of 19 (10.5%). EUS inappropriately classified 10 patients as T0 N0. Agreement between EUS and pathologic staging was poor for T (κ=0.14) and N status (κ=0.24). Median time from resection to death or last follow-up was 20 months. Pathologic T and N status were each significant predictors of survival (p=0.049 and p=0.0004, respectively). There were nonsignificant trends toward better survival for lower EUS T (p=0.32) and N status (p=0.0946). CONCLUSIONS Restaging by EUS before resection did not accurately predict pathologic stage in patients with esophageal cancer who received neoadjuvant treatment. As a result of this investigation, our institution no longer routinely performs restaging EUS.

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
PURPOSE To analyze the clinical implications of metastatic cervical lymph nodes in unresectable thoracic esophageal squamous cell carcinoma (SCC) after concurrent chemoradiotherapy (CRT). METHODS AND MATERIALS 208 thoracic esophageal SCC patients treated with concurrent CRT were analyzed retrospectively. Patients were divided into 3 groups according to different status of metastatic cervical lymph nodes: 1. CLN(-), no evidence of metastatic cervical lymph nodes; 2. CPLN(+), evidence of enlarged cervical paraesophageal lymph node without any other metastatic cervical lymph nodes; 3. OCLN(+), any other situations of enlarged cervical lymph nodes. The prognostic factors were examined univariately, then selected for inclusion in a multivariate Cox regression model. RESULTS Three-year OS of CLN(-),CPLN(+), and OCLN(+) groups were 39%, 33%, and 15% (logrank p=0.001). On univariate analysis, variables significantly associated with OS included sex, primary esophageal tumor location, length and cervical nodal disease. On multivariate analysis, primary tumor location (HR1.5, 95%CI 1.1-1.9, p=0.005), tumor length (HR1.5, 95%CI 1.1-2.0, p=0.010) and cervical nodal disease (HR1.2, 95%CI 1.0-1.5, p=0.014) were prognostic factors on OS. CONCLUSIONS (1) Primary tumor location, tumor length, and cervical nodal disease were significant prognostic factors on OS in esophageal SCC patients. (2) Patients with CPLN(+) disease tended to have a potential better long-term survival than those with OCLN(+) disease, and metastatic CPLN could be considered as local disease. The survival benefit in CPLN(+) subgroup might be contributed by the patients who presented with upper third thoracic tumors and shorter tumor length. Further investigation is needed.

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
OBJECTIVE The current American Joint Committee on Cancer staging system for esophageal cancer is based on lymph node location, irrespective of the number of involved and examined lymph nodes. METHODS We enrolled 488 patients receiving primary curative resection without neoadjuvant therapy for esophageal cancer between 1995 and 2006. The importance of total resected lymph node number (TLN) and metastatic lymph node number (MLN) and ratio (MLR) on patient survival was investigated. RESULTS The overall 3-year survival rate was 35.4%. The 3-year survival rate was equivalent among patients in N1 (23.3%), M1a (22.0%), and nonregional lymph node metastasis-related M1b (18.5%, p = 0.321). No survival difference was noted between patients with TLN < 15 or > or =15 (p = 0.249). Both MLN and MLR significantly predicted patient survival. The 3-year survival rate was 52.3%, 29.2%, and 8.0% for patients with MLN = 0, 1-3, and > or =4, respectively (p < 0.001). For patients with MLR = 0-0.2 or >0.2, the 3-year survival rate was 28.7% and 9.8%, respectively (p < 0.001). However, survival rate differences were more evident when TLN was more than 15. CONCLUSIONS We recommend designating both regional and nonregional lymph nodes as N nodes. MLN and MLR, but not TLN, are prognostic factors in esophageal cancer.

Abstract
BACKGROUND Patients with esophageal carcinoma and celiac, cervical, or other nonregional nodal metastases generally have a poor prognosis after surgical resection. Factors predicting long-term survival are unclear. The goal of this study was to analyze factors predicting long-term survival in this subset of patients. METHODS We conducted a retrospective review of a prospective database over a 20-year period to identify patients with resected esophageal carcinoma with nonregional lymph node metastases. Medical records were reviewed and risk factors were analyzed. RESULTS Sixty-seven patients underwent esophagectomy for M1a or M1b disease from 1987 to 2007. Esophagectomy was transthoracic in 62 patients and transhiatal in 5. The median number of lymph nodes harvested was 36. Sites of nodal metastases were the following: recurrent nodal chain in 42 patients, celiac in 20, both recurrent and celiac in 4, and paratracheal in 1. Median length of follow-up was 66 months. The 5-year overall survival for the entire cohort was 25%. The 5-year overall survival was significantly higher with earlier T-status, (pathologic tumor [pT]1/T2 vs pT3/T4; 62% vs 15%, p = 0.006). Thirteen patients who had nonregional nodal metastases without involvement of regional nodes (pN0) had a significant improvement in 5-year survival (67% vs 15%; p < 0.001). Patients with squamous cell carcinomas had higher 5-year survival compared with those with adenocarcinomas (42% vs 14%; p = 0.009). Patients treated with induction chemotherapy had prolonged 5-year survival (41%, p = 0.06) compared with those treated with adjuvant chemotherapy (11%) or no therapy (20%). Multivariate analysis demonstrated that chemotherapy treatment, squamous cell type, and early T stage (pT1/T2) are significant positive predictors of survival. CONCLUSIONS Surgical resection for patients with esophageal cancer associated with nonregional nodal metastases results in 25% survival at five years. Squamous histology, earlier T status, and perioperative chemotherapy are independent positive predictors of long-term survival.

Abstract
BACKGROUND There are few reports about abdominal lymph node metastasis of mid thoracic esophageal carcinoma. This study was designed to explore the pattern of abdominal lymph node metastasis in patients with mid thoracic esophageal squamous cell carcinoma and to evaluate the prognostic factors. METHODS The complete data of 368 patients with mid thoracic esophageal squamous cell carcinoma, who underwent modified Ivor-Lewis esophagectomy with two-field lymphadenectomy from January 1998 to January 2003, were reviewed. Survival rate was calculated by Kaplan-Meier method. Cox regression analysis was performed to identify risk prognostic factors. RESULTS Abdominal lymph node metastasis occurred in 58 (15.8%) patients: 34.5% (20/58) of them were stage T1 and T2. Skipping abdominal node metastasis was recognized in 13.8% (8/58) patients: all were stage T1 and T2. The overall 5-year survival rate of patients with abdominal lymph node metastasis (10.3%) was lower than that of those with thoracic node metastasis (18.3%). The prognosis of patients with distant abdominal lymph node metastasis was poor, and no one could survive more than 5 years. Cox regression analysis showed that five or more positive nodes and distant abdominal node metastasis were independent risk factors of patients with abdominal lymph node metastasis. CONCLUSIONS Abdominal lymph node metastasis in patients with mid thoracic esophageal squamous cell carcinoma occurred frequently, and the surgery favorable for extensive abdominal lymph node dissection should be selected. The prognosis of patients with abdominal lymph node metastasis was poor, especially those with more positive nodes and distant abdominal node metastasis.

Abstract
Esophageal malignancy is a major source of morbidity and mortality, despite the recently increased attention to screening and early detection. Prognosis for esophageal cancer remains grim, with advanced tumor stage and lymph node metastases conferring even graver outcomes. Several studies have demonstrated that the addition of preoperative neoadjuvant chemoradiotherapy may improve survival in patients with locally advanced tumor (T3) disease or local lymph node metastases. It is here that endoscopic ultrasonography finds its niche in the precise staging of these tumors and the subsequent use of stage-dependent treatment protocols.

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
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
OBJECTIVE To evaluate prognostic factors and tumor staging in patients after esophagectomy for cancer. SUMMARY BACKGROUND DATA Several reports have questioned the appropriateness of the sixth edition of the International Union Against Cancer (UICC) TNM guidelines for staging esophageal cancer. Additional pathologic characteristics, besides the 3 basic facets of anatomic spread (tumor, node, metastases), might also have prognostic value. METHODS All patients who underwent resection of the esophagus for carcinoma between January 1995 and March 2003 were extracted from a prospective database. Univariate and multivariate analysis was performed to identify prognostic factors for survival. The goodness of fit and accuracy of 3 staging models (UICC-TNM, Korst classification, Rice classification) predicting survival were assessed. RESULTS A total of 292 patients (mean age, 63 years) underwent esophagectomy. The 5-year overall survival rate was 29% (median, 21 months). pT-, pN-, pm-stage, and radicality of the resection were independent prognostic factors. Subdivision of T1 tumors into mucosal and submucosal showed significant differences in 5-year survival between both groups: 90% versus 47%, respectively (P = 0.01). Subdivision of pN-stage into 3 groups based on the number of positive nodes (0, 1-2, and >3 nodes positive) or the lymph node ratio (0, 0.01-0.2, and >0.2) also refined staging (P = 0.001 and P < 0.001, respectively). The current subclassification of M1 (M1a and M1b) is not warranted (P = 0.41). The staging model of Rice was more accurate than the UICC-TNM classification in predicting survival. CONCLUSION This study supports the view that the current (6th edition) UICC-TNM staging model for esophageal cancer needs to be revised.

Abstract
OBJECTIVES This is a report of mature results from a phase II trial of an accelerated multimodality treatment program for locoregionally advanced cancer of the esophagus and gastroesophageal junction with a focus on the impact of clinical heterogeneity on outcomes. A split course of pre- and postoperative hyperfractionated radiation therapy and concurrent chemotherapy was used in an effort to limit perioperative mortality. METHODS Eligibility required a diagnosis of esophageal or gastroesophageal junction cancer and an esophageal ultrasound stage of at least T3, N1, or M1A. Patients received a 12-day induction course of radiation (1.5 Gy twice a dose to a dose of 30 Gy) concurrent with 4-day continuous intravenous infusions of cisplatin (20 mg/m2 per day) and 5-fluorouracil (1000 mg/m2 per day) beginning on day 1. Surgery followed in 4 to 6 weeks followed 6 to 10 weeks later by a second, identical course of chemoradiotherapy. RESULTS From October 1999 through March 2003, 93 patients were enrolled; 96% were white, 86% male, and 83% had adenocarcinoma. Resection was possible in 83 patients (89%) with 4 (5%) perioperative deaths. With a median follow up of 50 months (range, 34-72 months), the 3-year projected overall survival rate is 27.9%, freedom from recurrence 30.5%, and distant metastatic control 32.4%. Locoregional control in resected patients is 86%. Freedom from recurrence and distant control were significantly better in patients with 1) earlier pretreatment clinical stage, 2) earlier postinduction pathologic stage, 3) squamous cell cancer, and 4) a pathologic response. CONCLUSIONS This accelerated multimodality treatment program is feasible and perioperative mortality proved acceptable. Despite excellent locoregional control, freedom from recurrence, and overall survival proved disappointing reflecting the frequency of distant metastases. Heterogeneity in patient populations makes comparisons with similar nonrandomized experiences problematic.

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
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
This study was undertaken to examine prognosis after resection for M1 disease in squamous cell esophageal carcinoma. Fifty-six patients with M1 esophageal cancer underwent esophageal resection with two or three-field nodal dissection from 1994 to 2001. Operative mortality occurred in 3 patients. Primary tumor sites were as follows; 10 upper, 23 middle, and 20 lower thoracic esophagus. They were found to have M1 disease by pathologic examination of dissected nodes, 24 M1a and 29 M1b. Forty-two patients (79%) were considered to have undergone curative resection. Chemotherapy and/or radiation therapy was given to 38 patients perioperatively. Recurrence was identified in 35 patients (66%) during a mean follow-up of 23 months. Overall median and 5-yr survivals were 19 months and 12.7%. Five-year survivals for M1a and M1b disease were 23.9% and 6.1%, respectively (p=0.0488). Curative resection tended to show better survival (p=0.3846). Chemotherapy and/or radiation therapy provided no advantage (p=0.5370). Multivariate analysis showed that M1b was significant risk factor over M1a disease. Our conclusion is that surgical resection can provide acceptable survival in thoracic squamous esophageal cancer with M1a disease. Survival differences between M1a and M1b disease support the current subclassification staging system.

Abstract
Carcinoma of the esophagus must be staged accurately before a treatment plan is initiated, and imaging studies play a major role in this process. Imaging for esophageal carcinoma involves evaluation of the locoregional extent of the tumor and distant metastatic disease. A CT scan of the chest and upper abdomen provides the most comprehensive information about esophageal carcinoma; however, accurate assessment of the depth of primary tumor invasion and lymph node status remains limited, even with newer generation scanners. Endoscopic US is a user-dependent modality that has emerged as a highly accurate technique in experienced hands to evaluate the depth of penetration of esophageal tumors, but its ability to detect metastatic lymph nodes is less impressive, leading some investigators to perform confirmatory needle aspiration of suspicious nodes. FDG-PET is a physiologic examination that is the subject of intense investigation in patients who have esophageal carcinoma. Preliminary studies have suggested that FDG-PET can detect otherwise radiographically occult distant metastatic disease in these patients, and changes in FDG uptake might correlate with the response to therapy. These findings need to be confirmed in larger studies. More sophisticated technology continues to be developed for imaging carcinoma of the esophagus, which will more than likely affect staging algorithms in the future.

Abstract
The management of patients with cancer of the distal thoracic esophagus is often made difficult by the presence of disease in the celiac axis lymph nodes. We investigated the outcome of such patients treated for cure in an attempt to better define the best treatment. The charts of all patients with esophageal cancer treated at the Department of Radiation Oncology at the Medical University of South Carolina between 1990 and 1998 were reviewed. Three groups of patients were analyzed: NoMo, N1Mo, and patients with positive celiac axis lymph nodes (M1a). Among 217 patients, 56 patients received radiotherapy with intent to cure, along with surgery, chemotherapy, or some combination of these modalities. Of these, 14 had disease of the distal esophagus with the celiac axis as their only site of distant disease. Comparison of survival curves in the three analyzed groups revealed no statistically significant differences in terms of overall survival (p = 0.3458 by the log-rank test) or disease-free survival (p = 0.5509 by the log-rank test). Patients with positive celiac axis lymph nodes as their only site of "M1" disease experienced a 2-year survival rate similar to "Mo" patients when treated with curative intent.

Abstract
OBJECTIVE We sought to evaluate the effectiveness of clinical staging of depth of tumor invasion (cT), the relationship of cT to survival, the benefits of downstaging cT, and the role of cT in treatment decisions. METHODS The accuracy of determining T by means of endoscopic ultrasonography and the relationship of cT to survival were assessed in 209 patients undergoing esophagectomy alone for esophageal carcinoma. The benefit of downstaging cT was assessed in 128 patients undergoing induction therapy and esophagectomy. The role of cT in treatment decisions was determined by integrating these results with the results of previous work. RESULTS Compared with pathologic T (pT), cT was 87% accurate, 82% sensitive, 91% specific, 89% positively predictive, and 86% negatively predictive of tumors confined to (< or =T2) or invading beyond (>T2) the esophageal wall. In cN0, increasing cT was predictive of progressively poorer survival. For each category of pT N0, cT accurately predicted survival, except for pT3, which was underestimated (P <.0001). In cN0, downstaging by induction therapy was beneficial only if tumors invaded beyond the wall (> or =cT3, P =.0003). In cN1, it was beneficial only when downstaging was synchronous in cT3/T4 (P <.001). CONCLUSIONS cT should be the principal determinant of treatment in cN0. In cN0, if endoscopic ultrasonography identifies tumors of greater than cT2, multimodality therapy should be considered. However, only when cT3/T4 tumors are downstaged to pT2 or less will patients benefit, but their survival will not equal that of patients with tumors of cT2 or less having esophagectomy alone. If endoscopic ultrasonography identifies tumors of cT2 or less, esophagectomy alone should be used because induction therapy might adversely affect survival.

Abstract
OBJECTIVE Cancer staging is dynamic, reflecting accrual of knowledge and experience in treatment. The objectives of this study were to assess current esophageal cancer staging and to determine whether refinements of classification and stage grouping are necessary. METHODS From 1983 through November 2000, 480 patients underwent esophagectomy without induction therapy. Depth of tumor invasion (T), regional lymph node status (N), distant status (M), number of metastatic regional lymph nodes, and histopathologic type and grade were subjected to survival-tree analysis, multivariable Cox and hazard function analysis, and residual misclassification risk analysis. RESULTS Inhomogenity of survival was found within and lack of distinction was found between current American Joint Committee on Cancer staging groups, supporting the need for refinement. T1 and N1 were redefined on the basis of survival differences. T1a is intramucosal cancer, T1b is submucosal cancer (P =.008), N1 is 1 or 2 metastatic regional lymph nodes, and N2 is 3 or more metastatic regional lymph nodes (P =.01). Current subclassification of M1 is not warranted (P =.9). Histopathologic type (P =.17) and grade (P =.3) minimally refined staging. Reassignment of staging groups constrained by American Joint Committee on Cancer definitions of stages 0 and IV produced less monotonic, distinctive, and homogeneous survival than free assignment of staging groups. CONCLUSIONS Current American Joint Committee on Cancer staging of esophageal cancer is inadequate. Refinement requires redefinition of T1, N1, and M1 classifications. Stage grouping within the constraints of American Joint Committee on Cancer definitions produces less accurate prognosis than free assignment based on survival data.

Abstract
BACKGROUND Postoperative survival of patients with esophageal cancers after curative surgery is strongly affected by the presence of lymph node metastasis. The number and location of lymph node metastases have been evaluated and graded, but the clinical significance of their size has not been well investigated. METHODS Of 322 esophageal cancer patients who underwent curative operations with radical lymph node dissection, 170 (53%) had lymph node metastasis. A total of 784 metastatic lymph nodes were obtained, and the area of the cancer nests was measured microscopically in the cross section. The data from each patient included the area of the largest cancer nest in the positive nodes (Nmax), classified as Na (<4 mm2), Nb (4-25 mm2), Nc (25-100 mm2), or Nd (>100 mm2). RESULTS The 170 patients were classified according to the Nmax value: Na, 31 (18.2%); Nb, 35 (20.5%); Nc, 49 (28.8%); and Nd, 55 (32.4%). The 5-year survival rate was 77.7% in patients without lymph node metastasis and 35.4% in those with lymph node metastasis. When classified by Nmax, the 5-year survival rate was 77.8% for Na, 63.9% for Nb, 18.8% for Nc, and 12.8% for Nd. There was no significant difference in the survival rate between Na patients and those without lymph node metastasis. Nmax showed significant correlation with the primary tumor size, depth of tumor invasion, and number and location of metastatic lymph nodes, but not with histologic type or primary tumor location. In multivariate analysis, the Nmax value, the number of lymph node metastases and depth of tumor invasion were independent prognostic factors, while the location of the lymph node metastases was not statistically significant. CONCLUSIONS The area of the largest cancer nest in the lymph nodes was one of the most significant prognostic factors for esophageal cancers. This estimation is objective and reproducible and may be of great importance when deciding the therapeutic modality for patients with esophageal cancers.

Abstract
BACKGROUND The prognosis of patients with esophageal cancer remains dismal, and their care poses a great challenge of customizing therapeutic strategies for individual patients. Lymph node staging is still less than ideal in esophageal cancer patients. Therefore, we investigated a new approach to lymph node analysis. METHODS One hundred eighty-seven patients curatively resected for squamous cell cancer of the esophagus were studied. The long diameter of the largest metastatic lymph node (MLN) was measured on a histopathologic slide and was considered as the MLN size. RESULTS Patient survival decreased with each millimeter increment in MLN size. By using MLN size as the lymph node classification criterion, patients with MLN <10 mm had both a significantly better overall and cancer-specific survival than those with MLN >or=10 mm. Patients with fewer than four MLNs were separated into prognostic groups according to the MLN size. Among the several prognostic factors, MLN size remained the strongest independent predictor of survival by multivariate analysis. This nodal analysis allowed stratification of patients into four stages with distinctly different survivals. CONCLUSIONS This approach supplements traditional nodal staging strategies and therefore has potential for guiding the development of treatment strategies in this carcinoma.

Abstract
BACKGROUND This study compares the health care costs and effectiveness of multiple staging options for patients with esophageal cancer. Techniques studied included computed tomographic (CT) scan, endoscopic ultrasound with fine-needle aspiration biopsy (EUS-FNA), positron emission tomography (PET), thoracoscopy/laparoscopy, and combinations of these. METHODS A decision-analysis model was constructed to compare different staging strategies. Costs were derived from the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked databases and from other Medicare reimbursement rates. Life expectancies were obtained from the 1973-1996 SEER database and adjusted for quality of life. Cost and effectiveness measures were discounted at 0% and 3% per year. Sensitivity and specificity measures were obtained from the published literature and a parallel prospective clinical trial, and all key variables were subjected to sensitivity analyses. RESULTS Under baseline assumptions, CT + EUS-FNA was the most inexpensive strategy and offered more quality-adjusted life-years, on average, than all other strategies with the exception of PET + EUS-FNA. The latter was slightly more effective but also more expensive. The marginal cost-effectiveness ratio for PET + EUS-FNA was $60,544 per quality-adjusted life-year. These findings were robust and changed very little in all of the sensitivity analyses. CONCLUSIONS The combination of PET + EUS-FNA should be the recommended staging procedure for patients with esophageal cancer, unless resources are scarce or PET is unavailable. In these instances, CT + EUS-FNA can be considered the preferred strategy.

Abstract
BACKGROUND The current TNM classification system does not consider tumor length or the number of lymph nodes in the staging and classification scheme for patients with esophageal carcinoma. Using data from the National Cancer Institute SEER Program, the authors explored the effect of tumor length and number of positive lymph nodes on survival in patients with esophageal carcinoma. METHODS Patients with esophageal adenocarcinoma or squamous cell carcinoma were subgrouped according to historic stage with localized, regional, or distant disease. Demographic factors (age at diagnosis, race, and gender) and tumor characteristics (morphology, histologic grade, tumor length, primary site, depth of invasion, number of positive lymph nodes, proportion of positive lymph nodes dissected, and distant metastatic sites) were examined. RESULTS Overall factors that were associated with an increased mortality risk included increasing age at diagnosis, black race versus white race, histologic grade, primary tumor site in the lower esophagus and abdomen versus upper regions, and increasing depth of invasion. Among patients with regional disease, the number of positive lymph nodes (>/= 5 vs. < 5) was related to an increasing risk (hazard ratio [HR], 1.29; 95% confidence interval [95%CI], 1.06-1.56). The proportion of positive lymph nodes compared with the number of lymph nodes dissected conferred an increased risk (HR, 1.63; 95%CI, 1.26-2.11). Among patients with distant disease, sites other than distant lymph nodes implied an increased mortality risk (HR, 1.37; 95%CI, 1.37-1.65). Tumor length was an independent predictor of mortality when controlling for depth of invasion in patients with localized disease (HR, 1.15; 95%CI, 1.08-1.21). CONCLUSIONS Tumor length, the number of involved lymph nodes, and the ratio of positive lymph nodes are important prognostic factors for survival in patients with esophageal carcinoma. A revised TNM classification system for patients with esophageal carcinoma might consider adding tumor length and number of positive lymph nodes as two important prognostic factors.

Abstract
BACKGROUND The purpose of this study was to determine how endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) with a histology confirmed biopsy protocol impacted on staging and managing esophageal carcinoma in terms of resectability and neoadjuvant therapy (chemotherapy and radiation therapy). METHODS The records of 40 consecutive patients diagnosed with esophageal cancer referred for EUS staging were reviewed. Computed tomography (CT) scan then EUS imaging and EUS-guided FNA staging, including involvement of celiac node (M1a stage), surgical pathology, and subsequent treatment were correlated. Through-the-scope balloons were used for dilatation when needed to examine the celiac nodes. RESULTS All 40 patients followed the protocol and were successfully imaged by EUS. Sixteen of the 40 required esophageal dilatation using the through-the-scope balloon. No complications were observed from esophageal dilatation for EUS. Twenty-three (58%) met the criteria for EUS-guided FNA biopsy from a total of 40 EUS imaging procedures. Twenty (87%) of the 23 EUS-guided FNA were directed toward the celiac nodes; 18 (90%) of the 20 were positive for malignancy and were treated by chemoradiation therapy and 2 (10%) FNA were negative for malignancy and were treated by surgical resection. The CT scan was able to detect only 6 (30%) of 20 cases of suspicious celiac lymph nodes, of which 5 (83%) were positive for malignancy by FNA. CONCLUSIONS EUS-guided FNA of celiac nodes (20 patients) directed management in all patients biopsied. EUS-guided FNA is superior to CT scan for diagnosing M1a disease. Protocol-directed EUS-guided FNA is a pivotal study when used in conjunction with stage-oriented treatment protocols for esophageal carcinoma.

Abstract
BACKGROUND The aims of this study were to determine the utility of EUS and EUS-guided fine needle aspiration (EUS-FNA) in the detection and confirmation of celiac lymph node metastasis in patients with esophageal cancer and to define EUS features predictive of celiac lymph node metastasis in these patients. METHODS The records of 211 patients with esophageal cancer who underwent EUS staging were reviewed. The operating characteristics of EUS were determined in patients where either surgery, EUS-FNA of a celiac lymph node, or both were performed (n = 102). The association between selected variables and the presence of celiac lymph node metastasis was evaluated by univariate and multivariable analyses. RESULTS EUS in 48 patients provided a true-positive diagnosis of celiac lymph node involvement, a false-positive and false-negative result, respectively, in 6 and 14 patients, and a true-negative diagnosis in 34 patients. The sensitivity of EUS in detecting celiac lymph node was 77% (95% CI [67, 88]), specificity 85% (95% CI [74, 96]), negative predictive value 71% (95% CI [58, 84]), and the positive predictive value 89% (95% CI [81, 97]). EUS-FNA was performed in 94% (51/54) of patients with celiac lymph nodes. The accuracy of EUS-FNA in detecting malignant celiac lymph nodes was 98% (95% CI [90, 100]). Advanced T-stage, the need for dilation, detection of peritumoral lymph nodes, and black race were associated with celiac lymph node involvement. In multivariable analysis, advanced T-stage was the strongest predictor of celiac lymph node involvement. CONCLUSION EUS and EUS-FNA are highly accurate in detecting and confirming celiac lymph nodes metastasis. Depth of tumor invasion as assessed by EUS is a strong predictor of celiac lymph node metastasis in patients with esophageal cancer.

Abstract
BACKGROUND Esophageal cancer patients with M1a disease are reported to have poor survival. We hypothesized that patients with celiac lymph node metastases (CLN) identified by endoscopic ultrasonography (EUS) would predict a cohort with significantly worse survival postoperatively. Accurate preoperative identification of this group will facilitate future adjuvant studies. METHODS During the study period, 211 patients with esophageal cancer underwent EUS staging. Patients with evaluable celiac axis (n = 182) were included in this study. Survival of patients with and without CLNs was compared and the factors affecting overall survival were assessed. A subgroup analysis based on CLN status was performed in the subgroup of patients who underwent surgical procedures. RESULTS Follow-up data was available in 91.2% (166 of 182) of the patients. As staged by EUS, T1, T2, T3, and T4 tumors accounted for 9.3%, 11.5%, 56%, and 21% of the cases, respectively. At least one CLN was imaged by EUS in 40% (72 of 182). The 5-year survival in patients with CLNs detected by EUS was 13% (95% confidence interval, 5% to 21%) compared with 30% (95% confidence interval, 21% to 40%) in patients with no CLNs detected by EUS (p = 0.007). In the subgroup of patients who underwent surgical procedures (n = 68), patients with CLN involvement had worse survival compared with those who did not have malignant involvement of CLNs at the time of their operation (median survival 39.8 versus 13.8 months, p = 0.0008). In a Cox proportional model, adjusting for race and the type of therapy, patients with CLN involvement or advanced EUS American Joint Committee on Cancer stage were more likely to have worse survival (p < 0.05) CONCLUSIONS EUS base line findings correlate with long term survival in patients with esophageal cancer. Patients with M1a disease as identified by EUS had a significantly worse postoperative survival when compared with non-M1a patients. This cohort of patients will be ideal for the study of induction therapy since the effect of down staging can be assessed before operation.
