Dayanamby A, Chmelo J, Bradshaw A, Phillips AW. Predictors of early recurrence of oesophagogastric adenocarcinoma after neoadjuvant FLOT. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108657. [PMID: 39241540 DOI: 10.1016/j.ejso.2024.108657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Revised: 07/17/2024] [Accepted: 09/02/2024] [Indexed: 09/09/2024]
Abstract
BACKGROUND Although survival of patients with oesophagogastric adenocarcinomas has improved over the years, rates of cancer recurrence remain high. There is limited research on predictors of early recurrence (ER), especially in patients receiving FLOT chemotherapy. The aim of this study was to investigate ER and survival rates and identify risk factors for ER. METHODS Patients receiving neoadjuvant chemotherapy with FLOT for oesophagogastric adenocarcinoma at single high-volume centre between August 2018 and January 2023 were evaluated for early recurrence defined as disease present within 1 year of surgery. Multivariable analysis was conducted to identify risk factors for ER. Patients who died in-hospital or within 90 days of surgery and those with positive longitudinal margin were excluded. RESULTS 196 patients were included. 93.3 % and 40.3 % of patients completed all four neoadjuvant and adjuvant cycles of FLOT respectively. 54 patients (27.6 %) developed recurrence in the follow up period with 27 patients (13.8 %) having ER. Recurrence free survival and overall survival at one year were 83.7 % and 90.8 % respectively. The estimated median survival after recurrence was 4.1 months. Extracapsular spread was found to be independent risk factor for ER (OR 4.565, 95 % CI 1.450-14.369, p = 0.009) in multivariable analyses together with ypN3 stage (OR 7.978, 95 % CI 1.339-47.534, p = 0.023). CONCLUSIONS The variables identified in this study may be helpful in determining patients at a higher risk of ER following curative surgery. Understanding these predictors may help tailor the follow up care of these patients, such as regular surveillance imaging, treatment, and frequency of reviews.

Eur J Surg Oncol 2021; 47:1875-1882. [PMID: 33795171 DOI: 10.1016/j.ejso.2021.03.247] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Revised: 03/08/2021] [Accepted: 03/20/2021] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Although extracapsular lymph node involvement (EC-LNI) has been proposed to be incorporated into the staging system of esophageal cancer, the prognostic value of EC-LNI remains controversial with conflicting data available, especially in the era of neoadjuvant therapy. METHODS An electronic literature search was undertaken using four public databases. Studies investigating the effects of EC-LNI on survival were included. In addition to analysis of the entire cohort, subset analyses were also performed to assess the impact of EC-LNI on patients receiving different treatment modalities. RESULTS A total of 20 studies were included in this meta-analysis. Pooling 13 studies on overall survival (OS), we observed that presence of EC-LNI was associated with significantly worse OS (HR = 2.09, 95%CI: 1.63-2.68; p < 0.01). Nine studies describing disease-free survival (DFS) included, the pooled data revealed that presence of EC-LNI was associated with significantly worse DFS (HR = 1.89, 95%CI: 1.63-2.20; p < 0.001). Subset analyses of patients receiving neoadjuvant therapy demonstrated a survival disadvantage of EC-LNI on OS (HR = 1.928, 95%CI: 1.196-3.107; p = 0.007) and DFS (HR = 1.985, 95%CI: 1.585-2.487; p < 0.001). Similar result was also seen in patients receiving primary surgery (OS: HR = 2.219, 95%CI: 1.720-2.864; p < 0.001; DFS: HR = 1.659, 95%CI: 1.285-2.141; p < 0.001). CONCLUSION EC-LNI is a strong prognostic predictor of inferior survival in patients with esophageal cancer irrespective of treatment modality. The currently pooled evidence indicates that EC-LNI has great potential to be incorporated into the future staging system.

Meta-analysis of prognostic factors of overall survival in patients undergoing oesophagectomy for oesophageal cancer. Dis Esophagus 2020; 33:5843554. [PMID: 32448903 DOI: 10.1093/dote/doaa038] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2020] [Revised: 03/25/2020] [Accepted: 04/17/2020] [Indexed: 12/11/2022]
Abstract
INTRODUCTION Currently, the American Joint Commission on Cancer (AJCC) staging system is used for prognostication for oesophageal cancer. However, several prognostically important factors have been reported but not incorporated. This meta-analysis aimed to characterize the impact of preoperative, operative, and oncological factors on the prognosis of patients undergoing curative resection for oesophageal cancer. METHODS This systematic review was performed according to PRISMA guidelines and eligible studies were identified through a search of PubMed, Scopus, and Cochrane CENTRAL databases up to 31 December 2018. A meta-analysis was conducted with the use of random-effects modeling to determine pooled univariable hazard ratios (HRs). The study was prospectively registered with the PROSPERO database (Registration: CRD42018157966). RESULTS One-hundred and seventy-one articles including 73,629 patients were assessed quantitatively. Of the 122 factors associated with survival, 39 were significant on pooled analysis. Of these. the strongly associated prognostic factors were 'pathological' T stage (HR: 2.07, CI95%: 1.77-2.43, P < 0.001), 'pathological' N stage (HR: 2.24, CI95%: 1.95-2.59, P < 0.001), perineural invasion (HR: 1.54, CI95%: 1.36-1.74, P < 0.001), circumferential resection margin (HR: 2.17, CI95%: 1.82-2.59, P < 0.001), poor tumor grade (HR: 1.53, CI95%: 1.34-1.74, P < 0.001), and high neutrophil:lymphocyte ratio (HR: 1.47, CI95%: 1.30-1.66, P < 0.001). CONCLUSION Several tumor biological variables not included in the AJCC 8th edition classification can impact on overall survival. Incorporation and validation of these factors into prognostic models and next edition of the AJCC system will enable personalized approach to prognostication and treatment.

Extracapsular Extension Does Not Decrease Overall Survival in Rectal Cancer Patients with Lymph Node Metastasis Following Neoadjuvant Chemoradiotherapy. GASTROENTEROLOGY INSIGHTS 2020. [DOI: 10.3390/gastroent11020004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/12/2022] Open
Abstract
Background. The Tumor-Node-Metastasis system does not include additional prognostic factors present in the Lymph Node Metastasis (LNM) such as extra-capsular extension (ECE), which is associated with decreased survival. There are not studies addressing this topic in rectal cancer patients with preoperative chemoradiotherapy (nCRT) and total mesorectal excision (TME). Aim. We aimed to examine the survival influence of ECE in patients with stage III rectal cancer who received nCRT followed by surgery. Methods. A retrospective study of 126 patients prospectively collected with rectal cancer in clinical stage III rated with nCRT and TME from 2010 to 2015 was performed. Results. In total, 71.6% of cases had 1 to 3 lymph node metastases, most tumors were grade 2 (52.4%), 25.4% had good pathologic response, 77.8% had a good quality TME, and the median tumor budding count was 4/0.785 mm2. Forty-four (34.9%) patients had ECE+, which was associated with a higher nodal stage (pN2), perineural invasion and a higher lymph node retrieval. The factors associated with the survival were a higher pathologic T stage, higher pathological N stage, high-grade tumors, and perineural invasion. The ECE did not decrease the 5–year survival with a similar median survival (86.5 months for the ECE+ group vs. 84.1 for the ECE–). Conclusion. Our results demonstrate that ECE has no impact on overall survival in rectal cancer patients who received nCRT and this was independent of nodal stage or number of lymph nodes examined.

Abstract
Background This study aimed to analyze the risk factors for esophageal squamous cell carcinoma (ESCC), especially extracapsular lymph node involving the esophagus (ECLNIE), occurring during or after radiotherapy (RT) in patients with esophageal perforation (EP). Methods In total, 306 patients with ESCC who received RT and/or chemotherapy between January 2016 and December 2017 in our hospital and who met the inclusion criteria of the study were recruited. The continuous variables were converted into classification variables using the receiver operating characteristic curve or common clinical parameters. Risk factors for EP were examined by univariable analysis using the chi-square test or Fisher’s exact and by multivariable analysis using logistic regression model. Propensity score matching (PSM) was used to compensate for the differences in baseline characteristics, and the incidence of EP was compared after matching. Results EP was observed in 26 patients (incidence rate, 8.5%). Univariable analysis revealed that age, BMI, T4 stage, tumor length, esophageal wall thickness, ECLNIE, necrotic areas, niche sign by esophagogram before RT, neutrophil-to-lymphocyte ratio, and prognostic nutritional index were significantly associated with EP among patients with ESCC who received radiotherapy. Multivariable analysis demonstrated that age, ECLNIE, esophageal wall thickness, and niche sign by esophagogram before RT were independent risk factors for EP. After PSM, compared with patients without ECLNIE, patients with ESCC and ECLNIE had a significantly higher risk of EP. Conclusion The presence of ECLNIE could be a strong risk factor of EP during and after RT.

Abstract
BACKGROUND The role of extracapsular lymph node involvement (ELNI) in esophageal cancer has not been fully investigated. We aim to assess its incidence and prognostic significance in patients with esophageal squamous cell carcinoma (ESCC) treated with and without neoadjuvant treatments. METHODS Data of patients who underwent esophagectomy for ESCC in a single medical center was retrospectively reviewed. Patients with positive lymph node involvement were classified as either with ELNI or without ELNI (intracapsular lymph node involvement, ILNI). The impact of ELNI on overall survival (OS), disease-free survival (DFS), and disease recurrence was analyzed. RESULTS A total of 336 patients, including 179 without (NCRT -) and 157 with (NCRT +) neoadjuvant chemoradiotherapy, were included. Seventy-two of 179 (40.2%) patients in NCRT - group were with positive lymph node, of whom 19 (26.4%) had ELNI, whereas 49 (31.2%) patients in NCRT + group had positive lymph node, of whom 25 (51.0%) had ELNI. In NCRT + group, patients with ELNI had worse outcome compared to those with ILNI in 5-year OS (10.4 vs. 13.8%, p = 0.008), and DFS (5.3 vs. 17.5%, p = 0.008). The presence of ELNI was also associated with more distant recurrence (p = 0.03). In contrast, there was no survival difference between patients with ELNI and ILNI in NCRT - group. CONCLUSIONS Compared with ILNI, ELNI is a significant poor prognostic factor in patients with ESCC treated with neoadjuvant treatments, but not in those with primary surgery.

Abstract
The extracapsular tumor extension (ECE) of nodal metastasis is an important prognostic factor in different types of malignancies. However, there is a lack of recent data in patients with non-small-cell lung cancer (NSCLC). In addition, the TNM staging system does not include ECE status as a prognostic factor. This systematic review and meta-analysis has been conducted to summarize and pool existing data to determine the prognostic role of ECE in patients with lymph node-positive NSCLC. Two authors performed an independent search in PubMed using a predefined keyword list, without language restrictions with publication date since 1990. Prospective or retrospective studies reporting data on prognostic parameters in subjects with NSCLC with positive ECE or with only intracapsular lymph node metastasis were retrieved. Data were summarized using risk ratios (RR) for the survival with 95% confidence intervals (CI). The data was analyzed using Mix 2 (ref: Bax L: MIX 2.0 - Professional software for meta-analysis in Excel. Version 2.015. BiostatXL, 2016. https://www.meta-analysis-made-easy.com ). There 2,105 studies were reviewed. Five studies covering a total of 828 subjects met the inclusion criteria and were included in the meta-analysis. Two hundred and ninety-eight (35.9%) patients were categorized as ECE+, of whom 54 (18.1%) survived at the end of follow-up. In the ECE-negative group, 257 patients (48.4%) survived by the end of follow-up. Thus, ECE status is associated with a significantly decreased survival rate: pooled RR 0.45 (95% CI 0.35-0.59), Q (4) = 4.06, P value = 0.39, and I 2 = 68.00% (95 CI 0.00-79.55%). In conclusion, ECE has a significant impact on survival in NSCLC patients and should be considered in diagnostic and therapeutic decisions in addition to the current TNM staging. Postoperative radiotherapy may be an option in ECE-positive pN1 NSCLC patients.

Abstract
BACKGROUND The clinical significance of pre-therapeutic nodal size in patients with esophageal squamous cell carcinoma (ESCC) is not clear. We investigated whether nodal size was correlated with survival in patients undergoing neo-adjuvant treatment followed by esophagectomy for ESCC. METHODS In 2009-2013, 222 patients who underwent neo-adjuvant treatment followed by esophagectomy for ESCC were enrolled in this retrospective study. Nodal size was measured along the short axis of the largest node using pre-therapeutic CT images. Patients were then stratified based on this short axis, and nodal size was correlated with clinicopathological factors and survival. RESULTS Patients with larger nodes were likely to have deeper cT, higher cN status, and poorer survival. Among the clinical factors cT, cN, cM, and nodal size, only cT and nodal size were independent prognostic factors in multivariate analysis [hazard ratio (HR) 2.0, 95 % confidence interval (CI) 1.1-3.5, p = 0.025 and HR 1.5, 95 % CI 1-2.3, p = 0.036, respectively]. In addition, nodal size was significantly associated with hematological recurrence (p = 0.007), but not lymphatic relapse (p = 0.272). CONCLUSIONS The short axis of the largest node before neo-adjuvant treatment in patients with ESCC is a prognostic factor.

Abstract
Answer questions and earn CME/CNE New to the eighth edition of the American Joint Committee on Cancer (AJCC) Cancer Staging Manual for epithelial cancers of the esophagus and esophagogastric junction are separate, temporally related cancer classifications: 1) before treatment decision (clinical); 2) after esophagectomy alone (pathologic); and 3) after preresection therapy followed by esophagectomy (postneoadjuvant pathologic). The addition of clinical and postneoadjuvant pathologic stage groupings was driven by a lack of correspondence of survival, and thus prognosis, between both clinical and postneoadjuvant pathologic cancer categories (facts about the cancer) and pathologic categories. This was revealed by a machine-learning analysis of 6-continent data from the Worldwide Esophageal Cancer Collaboration, with consensus of the AJCC Upper GI Expert Panel. Survival is markedly affected by histopathologic cell type (squamous cell carcinoma and adenocarcinoma) in clinically and pathologically staged patients, requiring separate stage grouping for each cell type. However, postneoadjuvant pathologic stage groups are identical. For the future, more refined and granular data are needed. This requires: 1) more accurate clinical staging; 2) innovative solutions to pathologic staging challenges in endoscopically resected cancers; 3) integration of genomics into staging; and 4) precision cancer care with targeted therapy. It is the responsibility of the oncology team to accurately determine and record registry data, which requires eliminating both common errors and those related to incompleteness and inconsistency. Despite the new complexity of eighth edition staging of cancers of the esophagus and esophagogastric junction, these key concepts and new directions will facilitate precision cancer care.

Lagarde SM, Navidi M, Gisbertz SS, van Laarhoven HWM, Sumpter K, Meijer SL, Disep B, Immanuel A, Griffin SM, van Berge Henegouwen MI. Prognostic impact of extracapsular lymph node involvement after neoadjuvant therapy and oesophagectomy. Br J Surg 2016; 103:1658-1664. [PMID: 27696382 DOI: 10.1002/bjs.10226] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2015] [Revised: 12/29/2015] [Accepted: 05/09/2016] [Indexed: 11/08/2022]
Abstract
BACKGROUND The significance of extracapsular lymph node involvement (LNI) is unclear in patients with oesophageal cancer who have undergone neoadjuvant treatment followed by oesophagectomy. The aim of this study was to assess the incidence and prognostic significance of extracapsular LNI in a large multicentre series of consecutive patients with oesophageal cancer treated by neoadjuvant chemotherapy or chemoradiotherapy and surgery. METHODS Data from a consecutive series of patients treated at two European centres were analysed. All patients with squamous cell carcinoma or adenocarcinoma of the oesophagus or gastro-oesophageal junction, who received neoadjuvant chemotherapy or chemoradiation followed by transthoracic oesophagectomy and two-field lymphadenectomy with curative intent, were included. RESULTS Between January 2000 and September 2013, 704 patients underwent oesophagectomy after neoadjuvant therapy. A median of 28 (range 5-77) nodes per patient was recovered. Some 347 patients (49·3 per cent) had no LNI (ypN0). Of the remaining 357 patients (50·7 per cent) with LNI (ypN1-3), extracapsular LNI was found in 190 (53·2 per cent). Five-year overall survival rates were 62·7 per cent for patients with N0 disease, 44·9 per cent for patients without extracapsular spread and 14·0 per cent where extracapsular LNI was identified (P < 0·001). Multivariable analyses demonstrated the presence of extracapsular LNI as an independent prognostic factor. CONCLUSION The presence of extracapsular LNI after neoadjuvant therapy carries a poor prognosis.

Abstract
CONTEXT Esophageal cancer continues to be one of the most lethal of all gastrointestinal malignancies. Its prognostic parameters are based on the gross and histopathologic examination of resected specimens by pathologists. OBJECTIVE To describe the implications of appropriate handling and examination of endomucosal resection and esophagectomy specimens from patients with esophageal carcinoma while considering the implications of the surgical techniques used to obtain such specimens. Parameters include histopathologic findings necessary for accurate staging, differences in the assessment of margins, residual malignancy, and criteria to evaluate for tumor regression after chemoradiation therapy as well as the role of immunohistochemistry and the judicious use of frozen sections. DATA SOURCES Sources were a review of the literature and the authors' experience handling these types of specimens. CONCLUSIONS Examining surgical specimens of the esophagus is critical in the management of patients with esophageal carcinoma, and it requires careful consideration of the diagnostic pitfalls, staging-related parameters, and results of molecular tests.

Abstract
OBJECTIVE The current pathological lymph node (pN) staging is based on the number of positive lymph nodes but does not take into consideration characteristics of the involved lymph nodes itself. The current study aims to examine the prognostic value of extracapsular lymph node involvement (EC-LNI) and intracapsular lymph node involvement (IC-LNI) for esophageal adenocarcinoma treated by primary surgery. METHODS From the databases of five European high volume centers, 1639 adenocarcinoma patients with primary R0-resection were withheld after excluding 90-day mortality. Oncologic variables, including number of resected lymph nodes, number of resected positive lymph nodes, and EC-LNI/IC-LNI were examined. The Union Internationale contre le Cancer (UICC) 7th edition prognostic staging was used as baseline staging system. Statistical analysis was performed by Cox proportional hazards modeling and verified using the Random Survival Forest technique. RESULTS EC-LNI showed significantly worse overall 5-year survival compared with IC-LNI overall (13.4% vs 37.2%, P < 0.0001), including in each pN-category [16.4% vs 45.6% in pN1 (P < 0.0001), 16.1% vs 23.8% (P = 0.047) in pN2 (P = 0.065), and 8.7% vs 26.3% in pN3 categories, respectively]. pN1 IC-LNI patients show a 5-year overall survival comparable (P = 0.92) with stage IIB (ie, pT3N0). Reclassifying the UICC prognostic stages according to these findings into an adapted staging model showed a significant (P < 0.0001) increase in homogeneity, discriminatory ability, and monotonicity compared with the original UICC TNM 7th edition prognostic staging. CONCLUSIONS These data suggest that lymph node capsular status is an important prognostic factor and should be considered for the future edition of the TNM staging system for esophageal cancer.

Abstract
The purpose of this study was to evaluate the presence of extracapsular invasion (ECI) in positive sentinel lymph nodes (SLNs) as a predictor of disease recurrence in breast cancer. SLN biopsy was performed on 318 breasts of 316 breast cancer patients, of which 50 (15.7%) had positive SLNs. Six (12.0%) of these 50 cases had disease recurrence. The clinicopathologic features of these cases were reviewed. The ECI at SLNs was not significantly associated with disease recurrence. The recurrence-free interval by Kaplan-Meier curves did not differ significantly among patients with and without ECI at SLNs. On the other hand, metastasis at non-SLNs was observed in 12 cases (24.0%) among the 50 cases with positive SLNs, and in the non-SLN metastasis group there were 7 patients with ECI at non-SLNs. Three of 7 cases with ECI at non-SLNs had disease recurrence and none of those 5 without ECI at non-SLNs had disease recurrence. Our current study suggests that the presence of ECI at metastatic SLNs is not associated with recurrent disease in breast cancer. Our results also imply that patients with ECI at positive non-SLNs have a high risk of disease recurrence.

Abstract
The aim of this study was to analyze the risk factors and prognosis for patients with esophageal perforation occurring during or after radiotherapy for esophageal carcinoma. We retrospectively analyzed 322 patients with esophageal carcinoma. These patients received radiotherapy for unresectable esophageal tumors, residual tumors after operation, or local recurrence. Of these, 12 had radiotherapy to the esophagus before being admitted, 68 patients had concurrent chemoradiotherapy (CRT), and 18 patients had esophageal perforation after RT (5.8%). Covered self-expandable metallic stents were placed in 11 patients. Two patients continued RT after stenting and control of infection; one of these suffered a new perforation, and the other had a massive hemorrhage. The median overall survival was 2 months (0-3 months) compared with 17 months in the non-perforation group. In univariate analysis, the Karnofsky performance status (KPS) being ≤ 70, age younger than 60, T4 stage, a second course of radiotherapy to the esophagus, extracapsular lymph nodes (LN) involving the esophagus, a total dose >100 Gy (biologically effective dose-10), and CRT were risk factors for perforation. In multivariate analysis, age younger than 60, extracapsular LN involving the esophagus, T4 stage, and a second course of radiotherapy to the esophagus were risk factors. In conclusion, patients with T4 stage, extracapsular LN involving the esophagus, and those receiving a second course of RT should be given particular care to avoid perforation. The prognosis after perforation was poor.

Abstract
PURPOSE The poor prognosis of gastroesophageal junction (GEJ) adenocarcinoma is largely associated with metastasis. We here report the first study to investigate the expression of epithelial-mesenchymal transition (EMT) markers Snail1 and E-cadherin in GEJ adenocarcinoma. METHODS Snail1 and E-cadherin were detected by immunohistochemistry in a cohort of 128 patients with surgically resected GEJ adenocarcinoma. We assessed the pathologic and prognostic relevance in all patients and within clinically different preserved E-cadherin and reduced E-cadherin-expressing sub-groups. RESULTS Immunoreactivity for Snail1 and E-cadherin was positive in 68 and 43 % of tumors, respectively. Snail1-positive tumors had more frequent lymph node metastasis and advanced tumor stage. E-cadherin expression was highly associated with histological differentiation, tumor size, advanced stage, presence of lymph node metastasis and distant metastasis. Patients with positive E-cadherin expression or negative Snail1 expression had significantly favorable overall survival rate. In E-cadherin-preserved tumors, the expression of Snail1 was related to lymph node metastasis, advanced stage and poor patient outcome. However, Snail1 expression had no statistically significant relationship with clinicopathologic parameters or prognosis in the reduced E-cadherin-expressing sub-group. Multivariate survival analysis identified that tumor stage [hazard ratio (HR) 2.440; 95 % confidence interval (CI) 1.216-4.896; P = 0.012], lymph node metastasis (HR 2.404; 95 % CI 1.188-4.867; P = 0.015) and gender (HR 3.244; 95 % CI 1.568-6.714; P = 0.002) were independent prognostic markers for overall survival. CONCLUSIONS Snail1 may act more critically in E-cadherin-positive tumors. Evaluation of Snail1 and E-cadherin in GEJ adenocarcinoma may help in assessing malignant properties and stratifying patients.

Abstract
The pathologist plays a critical role in the multidisciplinary team in charge of treating cancer patients, as many of the therapeutic decisions rely on the information conveyed through the pathology reports. The task of the pathologist includes not only an accurate assessment of pathological T and N categories, but also the evaluation of other indicators of prognosis including quality of surgery, margins of resection, as well as additional histopathological and molecular markers that influence prognosis and could predict response to therapy.

Abstract
OBJECTIVE The aim of this study was to analyze the incidence and impact of extracapsular lymph node spread (ELNS) in pancreatic cancer (PC) and cancer of the papilla of Vater (CPV). METHODS Between 2004 and 2009, 148 patients underwent surgical therapy for PC (n = 112) and CPV (n = 36). The resected lymph nodes (LNs) were further analyzed for ELNS. RESULTS In 95 (64.2%) patients, LN metastasis was present. In 45 (47.3%) of these patients, an ELNS was present on histopathology. The patients' survival was negatively affected by ELNS. For PC, the 5-year survival rate was 37% for patients with no LN metastasis compared with 4% and 0% for patients with LN metastasis (pN1) but without extracapsular LN involvement and patients with pN1 disease with extracapsular LN involvement of at least 1 LN, respectively (P < 0.001). In patients with CPV, the 5-year survival rate was 56% for patients with no LN metastasis and 44% and 0% for patients with pN1 disease but without extracapsular LN involvement and patients with pN1 disease with extracapsular LN involvement of at least 1 LN, respectively (P = 0.006). Multivariate analysis revealed ELNS as an independent prognostic factor of survival for both tumor types. CONCLUSIONS Extracapsular LN spread is an independent negative prognostic factor in PC and CPV. In future staging systems, ELNS should be included.

Abstract
BACKGROUND AND OBJECTIVES The purpose of this study is to estimate the effect of extranodal metastasis (EM) on recurrence and survival in patients with adenocarcinoma of the esophagogastric junction (AEG) after curative resection. METHODS Clinical data from 284 node-positive AEG patients who underwent curative resection were reviewed. Univariate and multivariate analyses were conducted to elucidate the effect of EM on recurrence-free survival (RFS) and overall survival (OS). RESULTS EM was detected in 70 (24.6%) of the 284 cases. It had a significant correlation with tumor size, Lauren type, histopathological grading, depth of tumor invasion, number of metastatic nodes, lymph node ratio, and TNM stage. The 5-year RFS and OS rates were 22.2% and 24.3%, respectively. Patients with EM had a significantly decreased RFS (16 vs. 36 months, P < 0.001) and OS (23 vs. 41 months, P < 0.001) compared with those without EM. Multivariate analyses identified EM as an independent prognostic factor (P = 0.003 and 0.001, respectively). CONCLUSION The presence of EM increases recurrence probability and reduces OS probability of AEG patients with lymph node metastasis. EM is a powerful prognostic factor reflecting a particularly aggressive biological behavior. Better understanding of EM status can help clinicians with regard to treatment decision and prognosis evaluation.

Abstract
BACKGROUND The prognostic importance of lymph node (LN) involvement for patients with adenocarcinoma of the esophagogastric junction (AEG) is well-known. In the latest edition of the UICC staging system, the number of metastatic LNs was taken into account, while the extent of lymphadenectomy (LAD) remains unaddressed. Removal of at least six LNs is recommended, but there is no defined minimum number as to classify as (y)pN0. We examined the prognostic value of the number of positive LNs, number of LNs removed, and LN ratio (LNR) in order to determine the influence of an adequate LAD on overall survival (OS). METHODS We analyzed data of 316 patients with AEG treated in our institution (2001-2011) regarding clinicopathological data, treatment, morbidity, mortality, and long-term prognosis. Univariate and multivariate analysis was performed using Cox regression to evaluate the prognostic impact of(y)pN category, number of LNs removed and LNR. RESULTS OS decreased with higher count of positive LNs (p < 0.001) and higher LNR (p < 0.001). Whether >6, >15, or >30 LNs were removed did not influence OS, neither in the entire study population nor within individual (y)pT or (y)pN categories. Multivariate analysis revealed LNR (p < 0.001) besides M category (p = 0.015) and tracheotomy during the postoperative course (p = 0.005) as independent predictors of OS. CONCLUSION The classification according to the number of involved LNs in the latest edition of the UICC staging system improves prognostication in patients with AEG. The importance of an adequate LAD is shown by the high prognostic relevance of the LNR rather than the absolute number of LNs removed.

Abstract
OBJECTIVES The 7th edition of American Joint Committee on Cancer (AJCC) staging system of oesophageal cancer and gastro-oesophageal junction has re-staged positive nodes into N1-3 according to the number of invaded lymph nodes (LNs). However, this new classification does not consider the potential negative impact of the extracapsular breakthrough on survival. This study aims at assessing prognosis according to whether LN involvement is intracapsular (ICLNI) or extracapsular (ECLNI) on disease-free survival (DFS) among the three sub-groups of LN-positive patients. METHODS Four hundred and sixteen consecutive R0 patients who underwent transthoracic oesophagectomy for cancer between 1996 and 2011 were retrospectively re-classified using the latest AJCC TNM classification. Among them, 230 (55%) patients have received a neoadjuvant chemoradiotherapy. Prognostic impact of ICLNI and ECLNI on DFS was assessed according to their new LN status. Multivariate analysis was drawn to determine factors affecting DFS. RESULTS Among the 416 patients, there were 138 (33%) patients with positive LN: 79 (57%) with ICLNI and 59 (43%) with ECLNI. The proportion of ECLNI was 21 of 73 (28%), 21 of 41 (51%) and 17 of 24 (70%) in N1, N2 and N3 patients, respectively. In N1 patients, median DFS was 48 months in ICLNI and 13 months in ECLNI (P = 0.068). In N2 patients, median DFS was 19 months in ICLNI and 9 months in ECLNI (P = 0.07). In N3 patients, median DFS was not reached in ICLNI and was 6 months in ECLNI (P = 0.002). On multivariate analysis, the ECLNI (P < 0.001, hazard ratio, HR: 2.51) and the post-T stage (P = 0.03, HR: 1.62) were the two independent factors affecting DFS. CONCLUSIONS Based on our limited study population, the existence of an ECLNI seems to have an additive negative impact on DFS, regardless of the pN stage. This suggests that extracapsular breakthrough status should be added to the new TNM staging system. This information has to be validated by further investigations.

Abstract
This paper investigates the association between protein retinoblastoma (pRB) loss and the T,N stage and prognosis in esophageal squamous cell carcinomas (ESCCs) using meta-analysis. We conducted a meta-analysis of 16 studies, comprising 1,117 patients to clarify this issue. All the studies searched by the electronic literature PubMed and http://www.KJEBM.com, which had been published during the period from January 1996 to January 2012 according to the inclusion criteria. Summary odds ratios (OR) were calculated using fixed or random-effects models. The summary odds ratios (ORs) for pRB inactive were 0.64 (95% confidence interval [CI]:0.45-0.91, P = 0.01) for T1/T2 versus T3/T4 tumors; summary OR = 0.69 (95% CI:0.51-0.94, P = 0.02) for N0 versus N1 tumors. The association between pRB loss and prognosis was examined in nine studies, and the summary hazard ratio was 1.39 (95% CI:1.11-1.74, P = 0.004). pRB inactive was significant associated with T3/T4 tumors and N1 stage as well as adverse prognosis for ESCCs. It appears warranted to prospectively validate that pRB loss may be used for subdividing the T,N stage evaluation of patients with ESCCs, and these patients may be the preponderant people for individualized treatment or target therapy.

Abstract
Gastroesophageal junction (GEJ) adenocarcinoma carries a poor prognosis that is largely attributable to early and frequent metastasis. The acquisition of metastatic potential in cancer involves epithelial-to-mesenchymal transition (EMT). The metastasis-associated gene MTA3, a novel component of the Mi-2/NuRD transcriptional repression complex, was identified as master regulator of EMT through inhibition of Snail to increase E-cadherin expression in breast cancer. Here, we evaluated the expression pattern of the components of MTA3 pathway and the corresponding prognostic significance in GEJ adenocarcinoma. MTA3 expression was decreased at both protein and mRNA levels in tumor tissues compared to the non-tumorous and lowed MTA3 levels were noted in tumor cell lines with stronger metastatic potential. Immunohistochemical analysis of a cohort of 128 cases exhibited that patients with lower expression of MTA3 had poorer outcomes. Combined misexpression of MTA3, Snail and E-cadherin had stronger correlation with malignant properties. Collectively, results suggest that the MTA3-regulated EMT pathway is altered to favor EMT and, therefore, disease progression and that MTA3 expression was an independent prognostic factor in patients with GEJ adenocarcinoma.

World J Surg Oncol 2012; 10:106. [PMID: 22681770 PMCID: PMC3502251 DOI: 10.1186/1477-7819-10-106] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2012] [Accepted: 04/08/2012] [Indexed: 01/01/2023] Open
Abstract
Background Lymph node metastasis is one of the most important prognostic factors for extra-hepatic bile duct carcinoma (ExHBDC). Extra capsular lymph node involvement (ExCLNI) is the extension of cancer cells through the nodal capsule into the perinodal fatty tissue. The prognostic impact of ExCLNI has been shown to be significant mainly in head and neck malignancies. Recently, the prognostic impacts of ExCLNI have evaluated in gastrointestinal malignancies. However no data is available regarding the incidence and prognostic significance of extra-capsular lymph node involvement (ExCLNI) in resectable ExHBDCs. The aim of the present study is first to evaluate the incidence of ExCLNI in surgically-treated ExHBDCs and second, to determine the prognostic impact of ExCLNI in patients with surgically-treated ExHBDCs. Methods A total of 228 patients (110 cases of hilar cholangiocarcinoma and 118 cases of distal cholangiocarcinoma) with surgically-treated ExHBDCs were included in this retrospective study. ExCLNI was defined as the extension of cancer cells through the nodal capsule into the perinodal fatty tissue. The existence of ExCLNI and its prognostic value were analyzed as a subgroup of lymph node metastasis. Results ExCLNI was detected in only 22% of patients with lymph node metastasis of surgically-treated ExHBDC. The presence of ExCLNI correlated with distal cholangiocarcinoma (p = 0.002). On univariate analysis for survival, perineural invasion, vascular invasion, histological grade, and lymph node metastasis were statistically significant factors. On multivariate analysis, only lymph node metastasis was identified as a significant independent prognostic factor in patients with resectable ExHBDC. Subgroups of lymph node metastasis including the presence of ExCLNI, location of lymph node metastasis, and the number of lymph node metastasis had no statistically significant impact on survival. Conclusion ExCLNI was present in only 22% of the LNM (7% of overall patients) in patients with surgical treated ExHBDCs. And ExCLNI would have no impact on the survival of patients with surgically-treated ExHBDCs.

Abstract
CyclinD1/pRb/ppRb is one of the most important pathways regulating the cell cycle, and related with the development of many cancers. However, the co-alteration of CyclinD1/pRb/ppRb in esophageal squamous cell carcinomas is less understood. This study aims to analyze the combined prognostic significance of cyclinD1 (CCND1) DNA amplification and the co-alteration of CCND1/pRb/ppRB in patients with esophageal squamous cell carcinoma. CCND1 DNA amplification and the protein expression of CCND1, pRb, and ppRb on 100 tumor specimens and 11 normal tissues were detected using real-time quantitative reverse transcription polymerase chain reaction and immunohistochemistry, respectively. Their prognosis significance was analyzed by Kaplan-Meier method. We found that 41% of the patients had CCND1 DNA amplification, which had a short survival time compared with the patients without CCND1 amplification (25.63 months vs. not reached, P=0.007). The patients with the co-alternation of CCND1(+) /pRb(-) /ppRb(+) protein expression levels have a poorer overall survival than the others (11.4 vs. 43.4 months, P=0.001). Cox regression analysis showed that the co-alternation of CCND1/pRb/ppRb and CyclinD1 amplification were the two most independent prognosis factors of patients with esophageal cancer. These findings suggested that CCND1 amplification and co-alternation of CCND1(+) /pRb(-) /ppRb(+) may play a crucial role in the prognostic evaluation of patients with esophageal cancer, and the patients with CCND1(+) /pRb(-) /ppRb(+) have the worst prognosis in all the patients. The results also indicated that the patients with CCND1 amplification or co-alternation of CyclinD1(+) /pRb(-) /ppRb(+) might be the preponderant people for therapy targeting the CCND1/pRb/ppRb pathway in the future.

Abstract
Oesophageal cancer is the 7th most common cause of cancer-related death in the developed world and the incidence of oesophageal adenocarcinoma is now the fastest growing of any gastrointestinal cancer. Lymph node involvement is the single most important prognostic factor in oesophageal cancer. Imaging to determine the extent of lymph node involvement and plan treatment often requires a combination of modalities to avoid under-staging. The 7th edition of the staging system released by the International Union Against Cancer (IUCC) has stratified lymph node involvement according to the number of lymph nodes involved and redefined its groupings for location of metastatic lymph node involvement. This review discusses the prognostic and treatment implications of these modifications and explores micrometastatic lymph node involvement, capsular infiltration and lymph node ratio as possible additions to the staging system.

Abstract
BACKGROUND We previously demonstrated that extracapsular invasion (ECI) at a metastatic sentinel node was significantly associated with the presence of positive non-sentinel nodes in patients with breast cancer. However, the mechanism of metastatic spreading of tumor cells to distant lymph nodes in patients with colorectal carcinoma is not fully understood. In this study, we investigated the factors that may determine the likelihood of additional regional lymph node metastasis when metastasis is found in nodes at the N1 site in colorectal cancer, especially focusing on the presence of ECI. METHODS Two hundred and twenty-eight consecutive patients who underwent colorectal resection were identified for inclusion in this study, of which 37 (16.2%) had positive lymph nodes at the N1 site. Six of these 37 cases had additional metastasis in N2 site lymph nodes. We reviewed the clinicopathological features of these cases and performed statistical analysis of the data. RESULTS In the univariate analysis ECI at the N1 site was the only factor significantly associated with the presence of cancer cells in the N2 site. Other factors, including number of positive lymph nodes, lymphovascular invasion of the primary tumor, tumor size and tumor depth of invasion, were not associated with metastatic involvement at the N2 site. CONCLUSIONS Our results suggest that the presence of ECI at metastatic lymph nodes at the N1 site is correlated with further metastasis at the N2 site. These findings imply the possibility that ECI might indicate the ability of colorectal tumor cells to disseminate to distant lymph nodes.

Abstract
AIM: To evaluate the presence of extracapsular invasion (ECI) in positive nodes as a predictor of disease recurrence disease in colorectal cancer.
METHODS: Two hundred and twenty-eight consecutive patients who underwent colorectal resection were identified for inclusion in this study, of which 46 had positive lymph nodes. Among 46 cases with stage IIIcolorectal cancer, 16 had ECI at positive nodes and 8 had disease recurrence. The clinical and pathological features of these cases were reviewed.
RESULTS: In the univariate analysis, the number of positive lymph nodes and depth of tumor invasion were significantly associated with the presence of ECI at positive nodes. Multivariate analysis demonstrated that only ECI was a predictor of recurrence. The recurrence-free interval differed significantly among patients with ECI at positive nodes.
CONCLUSION: Our results suggest that ECI at metastatic nodes can identify which cases are at high risk of short-term disease recurrence in colorectal cancer.

Abstract
OBJECTIVE To identify and describe clinicopathologic prognostic factors in patients with esophageal adenocarcinoma who underwent surgical resection with curative intent. PATIENTS AND METHODS The study cohort consisted of 796 patients with adenocarcinoma of the esophagus, gastroesophageal junction, or gastric cardia who underwent complete tumor resection at Mayo Clinic from January 1, 1980, to December 31, 1997. We reviewed individual patient medical records and abstracted demographic, pathologic, perioperative, and cancer outcome data. Median follow-up for vital status and disease recurrence was 12.8 and 5.8 years, respectively. RESULTS Univariate analysis revealed the following factors to be statistically associated with worse 5-year disease-specific survival: higher N and T status, higher tumor grade, age older than 76 years, and the presence of extracapsular lymph node extension and signet ring cells. The following factors remained significantly linked with worse 5-year disease-specific survival on multivariate analysis: higher N and T status, grade, and age and the absence of preoperative chemotherapy or radiotherapy. Anatomic location of tumor was not associated with differential prognosis. Lymph node metastases were found in 25 (27%) of 93 T1b tumors, 397 (85%) of 468 T3 tumors, and 22 (67%) of 33 T4a tumors. Disease-specific survival was better in T3-4N0 than in T1bN1-3 carcinomas (hazard ratio, 0.50; 95% confidence interval, 0.28-0.89, adjusted for grade and age; P=.02). CONCLUSION Our results confirm the importance of T and N status and tumor grade and suggest that age may affect prognosis. In addition, we show that a significant proportion of superficial esophageal adenocarcinomas exhibit regional metastases and have worse prognosis than more invasive nonmetastatic tumors.

Abstract
BACKGROUND Tumour stroma ratio (TSR) in histological sections of resected oesophageal adenocarcinomas proved to be a prognostic factor for patients' survival. The objectives of this study were to assess inter- and intraobserver agreement for TSR scoring on biopsy material and to validate these biopsy results with the results derived from surgical specimens. METHODS Biopsies and surgical specimens of 91 patients with oesophageal adenocarcinoma were available. TSR was determined on the original haematoxylin-eosin (H&E) tissue sections from primary tumour biopsies. To assess interobserver variation, TSR was scored by three pathologists as 0-25%, 25-50%, 50-75% or 75-100%. A second scoring was done to examine intraobserver variation. The definitive TSR biopsy score was compared with the corresponding resection specimen score. Kappa statistics were applied to evaluate agreement. RESULTS Biopsies of 10 (11%) patients were rejected because of poor quality. For 81 TSR biopsy scores, interobserver correlations ranged between 0.239 and 0.486 (P < 0.001 for all). By classifying scores into two groups (<50% and ≥ 50%), interobserver correlations ranged between 0.372 and 0.886 (P < 0.001 for all). Intraobserver agreement was substantial to near-perfect (κ = 0.780-0.848; P < 0.001 for all). Definitive TSR biopsy score showed moderate correlation with TSR scores on surgical specimens (κ = 0.506), but it was an independent prognostic factor for survival. CONCLUSION Reproducibility of tumour stroma ratio scoring on oesophageal adenocarcinoma biopsies was good. The ease of TSR scoring on H&E sections together with its correlation with patients' survival may have clinical relevance in this era of neoadjuvant therapy.

Abstract
CONTEXT Colorectal cancer is the leading cause of morbidity and death among gastrointestinal tumors and ranks fourth after lung, breast, and ovarian cancers. Despite a continuous refinement of the T (tumor), N (node), and M (metastasis) staging system to express disease extent and define prognosis, and eventually to guide treatment, the outcome of patients with colorectal cancer may vary considerably even within the same tumor stage. Therefore, the need for new factors, either morphologic or molecular, that could more precisely stratify patients into different risk categories is clearly warranted. OBJECTIVES To present the state of the art with regard to the colorectal cancer staging system and to discuss confusing and/or challenging issues, including the assessment of peritoneal membrane involvement, vascular invasion, tumor deposits, and pathologic tumor response to neoadjuvant chemoradiotherapy. DATA SOURCES Literature review of relevant articles indexed in PubMed (US National Library of Medicine) and primary material from the authors' institutions. CONCLUSIONS Two emerging needs exist for the TNM system, namely, further stratification of patients with the same tumor stage and incorporation of nonanatomic factors, the latter including molecular and treatment factors. The identification and classification of morphologic features encountered in the pathologic examination of colorectal cancer specimens may be difficult and a source of subjective variability. Enhanced pathologic analysis, agreed-upon standard protocols, and standardization should improve the completeness and accuracy of pathology reports.

Abstract
AIM: To assess the effects of neoadjuvant chemoradiotherapy (CRT) on the presence of extracapsular lymph node involvement (LNI) and its prognostic value in patients with resected esophageal cancer.
METHODS: Two hundred and ninety-eight patients with advanced esophageal cancer underwent esophagectomy between 1997 and 2006. One hundred and ninety patients (63.8%) were treated with neoadjuvant CRT prior to resection. A total of 986 metastatic LNs were examined. Survival of the patients was analyzed according to intra- and extra-capsular LNI.
RESULTS: Five-year survival rate was 22.5% for the entire patient population. Patients with extracapsular LNI had a 5-year survival rate of 16.7%, which was comparable to the 15.8% in patients with infiltrated nodes of the celiac trunk (pM1lymph). In contrast to patients treated with surgery alone, neoadjuvant therapy resulted in significantly (P = 0.001) more patients with pN0/M0 (51.6% vs 25.0%). In 17.6% of the patients with surgery alone vs 16.8% with neoadjuvant CRT, extracapsular LNI was detected. Neoadjuvant therapy does not reduce the occurrence of extracapsular LNI.
CONCLUSION: Extracapsular LNI is an independent negative prognostic factor not influenced by neoadjuvant CRT. In a revised staging system for esophageal cancer, extracapsular LNI should be considered.

Abstract
BACKGROUND Lymphatic spread is 1 of the most relevant prognostic factors for gastric carcinoma. The current International Union Against Cancer (UICC) pN staging system is based on the number of metastatic lymph nodes and does not take into consideration the characteristics of the metastatic lymph nodes itself. The aim of the current study was to examine the prognostic value of extracapsular lymph node involvement in gastric cancer and to find correlations with clinicopathological parameters. METHODS Tissue samples were obtained from 159 gastric cancer patients who underwent gastrectomy with D2-lymphadenectomy in 142 (89.3%) cases and subtotal gastrectomy with D2-lymphadenectomy in 17 (10.7%) cases. The number of resected lymph nodes, number of metastatic lymph nodes, and number of metastatic lymph nodes with extracapsular lymph node involvement were determined. Extracapsular spread was defined as infiltration of cancer cells beyond the capsule of the metastatic lymph node. RESULTS Ninety-six (60.4%) patients had lymph node metastasis. In 57 (35.8%) cases, extracapsular lymph node involvement was also detected. Extracapsular lymph node involvement was significantly associated with higher pN-category (P < .001), higher pM category (P = .048), and higher UICC stages (P = .001). According to the Kaplan-Meier log-rank statistical method, extracapsular lymph node involvement was significantly associated with poor survival (P = .001). In the multivariate analysis besides pT (P < .001) and R-category (P = .009), extracapsular lymph node involvement also remained as an independent prognostic factor (P = .003), whereas the UICC pN-category (P = .822) lost its prognostic value. CONCLUSIONS Extracapsular lymph node involvement is associated with higher tumor stages and is an independent negative prognostic factor in gastric cancer. In future staging systems for gastric cancer, extracapsular lymph node involvement should be considered.

Abstract
OBJECTIVE To evaluate the prognostic value of the tumour stroma ratio (TSR) in resected adenocarcinoma of the oesophagus. BACKGROUND In the literature, a refinement of oesophageal cancer staging has been proposed. Recently, TSR has been identified as a histological characteristic of the tumour itself that proved to be a strong predictor for survival in colorectal cancer. METHODS In our cancer registry database, we identified 93 consecutive patients who underwent resection for oesophageal adenocarcinoma between 1990 and 2004 in two hospitals in our region. Using a predefined histopathological protocol, TSR was determined on the original haematoxylin-eosin (H&E) tissue sections of oesophagectomy specimens by two independent investigators. RESULTS With a cut-off value of 50% tumour/stroma, patients were classified as TSR high (n=60) or TSR low (n=33). There were no significant differences in patient, tumour and treatment characteristics between the two groups, except for M status (M1a) and radicality of resection. The (disease-free) survival in the TSR high group was significantly better than in the TSR low group. By multivariate analysis, TSR was identified as a highly significant prognostic factor for overall survival (HR 2.0; P=0.010), independent of depth of tumour invasion, nodal status, lymph node ratio, extracapsular involvement, TNM stage, histological grade and radicality of resection. CONCLUSION TSR is a new and practicable prognostic tumour characteristic for oesophageal adenocarcinoma that can discriminate patients with a poor outcome from those with a better outcome.

Abstract
Carcinoma of the oesophagus including carcinoma of gastro-oesophageal junction are rapidly increasing in incidence. During recent years there have been changes in the knowledge surrounding biology of the disease progression. Identification of dysplasia in mucosal biopsies is the most reliable pathologic indicator of an increased risk of development of squamous cell carcinoma and passes through the sequence of chronic esophagitis, low-grade and high-grade dysplasia and invasive carcinoma. Although Barrett's esophagus is a precursor to esophageal adenocarcinoma and have a well described sequence of carcinogenesis: the Barrett's metaplasia-dysplasia-adenocarcinoma sequence, not all patients with this disorder require intensive surveillance. The natural history of dysplasia is poorly understood, particularly in low-risk regions, and prospective follow-up studies are needed. Adjunctive methods to improve reproducibility, such as immunostaining for alpha-methylacyl-coenzyme A racemase (AMACR), show promise, but require confirmation in larger studies. In addition, several controversial methods such as detection of p16, p53, and DNA content abnormalities may help identify patients at particularly high risk for progression to cancer, but these techniques are not yet widely available for routine clinical application. More studies are needed to define other early nonmorphologic biomarkers for risk of squamous cell carcinoma. Recent evidence regarding the importance of several histopathologically derived prognostic factors, such as circumferential resection margin status and lymph node metastases are evaluated, including lymph node micrometastases and the sentinel node concept. With the rising use of multimodal treatments for oesophageal cancer it is important that the response of the tumour to this therapy can be carefully documented by histopathology.

Abstract
PURPOSE Previous studies have reported that extranodal spread is a prognostic factor in patients with several solid cancers. However, the definition of extranodal spread varies with the reporting investigator and has not been standardized yet. Therefore, we selected several widely used definitions from previous reports and comparatively assessed the clinicopathologic significance of these definitions. METHODS Extranodal spread in the 103 node-positive patients who had received curative resections for gastric cancer was classified into two groups, viz., (a) capsule rupture, where cancer cells infiltrated into the perinodal fatty tissue beyond the capsule of the involved lymph node, and (b) no capsule rupture, where nests of cancer cells were detected demonstrable in adjacent tissues around the metastatic lymph node without rupture of the capsule. RESULTS Sixty-five (63.1%) of the 103 patients showed extranodal spread. Of the 65 patients, 50 patients showed the capsule rupture type and 15 showed the no capsule rupture type of extranodal spread. The 5-year survival rate was significantly poorer in the capsule rupture group as compared with that in the no capsule rupture group and extranodal spread-negative group (P < 0.05 and P < 0.01, respectively). In regard to the mode of recurrence, the rate of peritoneal recurrence was significantly higher in the capsule rupture group (P < 0.01). CONCLUSIONS In the assessment of patients with extranodal spread, it is considered important to classify the patients based on the status of extranodal spread into the capsule rupture group and no capsule rupture group.

Abstract
AIMS To analyse tumour characteristics and the prognostic significance of prostatic cancers with extranodal extension of lymph node metastases (ENE) in 102 node-positive, hormone treatment-naive patients undergoing radical prostatectomy and extended lymphadenectomy. METHODS AND RESULTS The median number of nodes examined per patient was 21 (range 9-68), and the median follow-up time was 92 months (range 12-191). ENE was observed in 71 patients (70%). They had significantly more, larger and less differentiated nodal metastases, paralleled by significantly larger primary tumours at more advanced stages and with higher Gleason scores than patients without ENE. ENE defined a subgroup with significantly decreased biochemical recurrence-free (P = 0.038) and overall survival (P = 0.037). In multivariate analyses the diameter of the largest metastasis and Gleason score of the primary tumour were independent predictors of survival. CONCLUSIONS ENE in prostatic cancer is an indicator lesion for advanced/aggressive tumours with poor outcome. However, the strong correlation with larger metastases suggests that ENE may result from their size, which was the only independent risk factor in the metastasizing component. Consequently, histopathological reports should specify the true indicator of poor survival in the lymphadenectomy specimens, which is the size of the largest metastasis in each patient.

Abstract
Tissue microarray (TMA) technology has been developed to facilitate high-throughput immunohistochemical and in situ hybridization analysis of tissues by inserting small tissue biopsy cores into a single paraffin block. Several studies have revealed novel prognostic biomarkers in esophageal squamous cell carcinoma (ESCC) by means of TMA technology, although this technique has not yet been validated for these tumors. Because representativeness of the donor tissue cores may be a disadvantage compared to full sections, the aim of this study was to assess if TMA technology provides representative immunohistochemical results in ESCC. A TMA was constructed containing triplicate cores of 108 formalin-fixed, paraffin-embedded squamous cell carcinomas of the esophagus. The agreement in the differentiation grade and immunohistochemical staining scores of CK5/6, CK14, E-cadherin, Ki-67, and p53 between TMA cores and a subset of 64 randomly selected donor paraffin blocks was determined using kappa statistics. The concurrence between TMA cores and donor blocks was moderate for Ki-67 (κ = 0.42) and E-cadherin (κ = 0.47), substantial for differentiation grade (κ = 0.65) and CK14 (κ = 0.71), and almost perfect for p53 (κ = 0.86) and CK5/6 (κ = 0.93). TMA technology appears to be a valid method for immunohistochemical analysis of molecular markers in ESCC provided that the staining pattern in the tumor is homogeneous.
