Abstract
BACKGROUND Lymph node metastasis (LNM) is possible after endoscopic resection of early esophageal adenocarcinoma (EAC). This study aimed to develop and internally validate a prediction model that estimates the individual risk of metastases in patients with pT1b EAC. METHODS A nationwide, retrospective, multicenter cohort study was conducted in patients with pT1b EAC treated with endoscopic resection and/or surgery between 1989 and 2016. The primary end point was presence of LNM in surgical resection specimens or detection of metastases during follow-up. All resection specimens were histologically reassessed by specialist gastrointestinal pathologists. Subdistribution hazard regression analysis was used to develop the prediction model. The discriminative ability of this model was assessed using the c-statistic. RESULTS 248 patients with pT1b EAC were included. Metastases were seen in 78 patients, and the 5-year cumulative incidence was 30.9 % (95 % confidence interval [CI] 25.1 %-36.8 %). The risk of metastases increased with submucosal invasion depth (subdistribution hazard ratio [SHR] 1.08, 95 %CI 1.02-1.14, for every increase of 500 μm), lymphovascular invasion (SHR 2.95, 95 %CI 1.95-4.45), and for larger tumors (SHR 1.23, 95 %CI 1.10-1.37, for every increase of 10 mm). The model demonstrated good discriminative ability (c-statistic 0.81, 95 %CI 0.75-0.86). CONCLUSIONS A third of patients with pT1b EAC experienced metastases within 5 years. The probability of developing post-resection metastases was estimated with a personalized predicted risk score incorporating tumor invasion depth, tumor size, and lymphovascular invasion. This model requires external validation before implementation into clinical practice.

Abstract
Endoscopic resection (ER) is an important diagnostic step in management of patients with early Barrett's esophagus (BE) neoplasia. Based on ER specimens, an accurate histological diagnosis can be made, which guides further treatment. Based on depth of tumor invasion, differentiation grade, lymphovascular invasion, and margin status, the risk of lymph node metastases and local recurrence is judged to be low enough to justify endoscopic management, or high enough to warrant invasive surgical esophagectomy. Adequate assessment of these histological risk factors is therefore of the utmost importance. Aim of this study was to assess pathologist concordance on these histological features on ER specimens and evaluate causes of discrepancy. Of 62 challenging ER cases, one representative H&E slide and matching desmin and endothelial marker were digitalized and independently assessed by 13 dedicated GI pathologists from 8 Dutch BE expert centers, using an online assessment module. For each histological feature, concordance and discordance were calculated. Clinically relevant discordances were observed for all criteria. Grouping depth of invasion categories according to expanded endoscopic treatment criteria (T1a and T1sm1 vs. T1sm2/3), ≥1 pathologist was discrepant in 21% of cases, increasing to 45% when grouping diagnoses according to the traditional T1a versus T1b classification. For differentiation grade, lymphovascular invasion, and margin status, discordances were substantial with 27%, 42%, and 32% of cases having ≥1 discrepant pathologist, respectively. In conclusion, histological assessment of ER specimens of early BE cancer by dedicated GI pathologists shows significant discordances for all relevant histological features. We present propositions to improve definitions of diagnostic criteria.

Abstract
Aim To quantify lymphovascular invasion (LVI) and to assess the prognostic value in patients with pT1b esophageal adenocarcinoma. Methods In this nationwide, retrospective cohort study, patients were included if they were treated with surgery or endoscopic resection for pT1b esophageal adenocarcinoma. Primary endpoint was the presence of metastases, lymph node metastases, or distant metastases, in surgical resection specimens or during follow‐up. A prediction model to identify risk factors for metastases was developed and internally validated. Results 248 patients were included. LVI was distributed as follows: no LVI (n = 196; 79.0%), 1 LVI focus (n = 16; 6.5%), 2–3 LVI foci (n = 21; 8.5%) and ≥4 LVI foci (n = 15; 6.0%). Seventy‐eight patients had metastases. The risk of metastases was increased for tumors with 2–3 LVI foci [subdistribution hazard ratio (SHR) 3.39, 95% confidence interval (CI) 2.10–5.47] and ≥4 LVI foci (SHR 3.81, 95% CI 2.37–6.10). The prediction model demonstrated a good discriminative ability (c‐statistic 0.81). Conclusion The risk of metastases is higher when more LVI foci are present. Quantification of LVI could be useful for a more precise risk estimation of metastases. This model needs to be externally validated before implementation into clinical practice.

Abstract
The ReBus cohort is a matched nested case-control cohort of patients with nondysplastic (ND) Barrett's esophagus (BE) at baseline who progressed (progressors) or did not progress (nonprogressors) to high-grade dysplasia (HGD) or cancer. This cohort is constructed using the most stringent inclusion criteria to optimize explorative studies on biomarkers predicting malignant progression in NDBE. These explorative studies may benefit from expanding the number of cases and by incorporating samples that allow assessment of the biomarker over space (spatial variability) and over time (temporal variability). To (i) update the ReBus cohort by identifying new progressors and (ii) identify progressors and nonprogressors within the updated ReBus cohort containing spatial and temporal information. The ReBus cohort was updated by identifying Barrett's patients referred for endoscopic work-up of neoplasia at 4 tertiary referral centers. Progressors and nonprogressors with a multilevel (spatial) endoscopy and additional prior (temporal) endoscopies were identified to evaluate biomarkers over space and over time. The original ReBus cohort consisted of 165 progressors and 723 nonprogressors. We identified 65 new progressors meeting the same strict selection criteria, resulting in a total number of 230 progressors and 723 matched nonprogressors in the updated ReBus cohort. Within the updated cohort, 61 progressors and 107 nonprogressors (mean age 61 ± 10 years) with a spatial endoscopy (median level 3 [2-4]) were identified. 33/61 progressors and 50/107 nonprogressors had a median of 3 (2-4) additional temporal endoscopies. Our updated ReBus cohort consists of 230 progressors and 723 matched nonprogressors using the most strict selection criteria. In a subgroup of 168 Barrett's patients (the SpaTemp cohort), multiple levels have been sampled at baseline and during follow-up providing a unique platform to study spatial and temporal distribution of biomarkers in BE.

Abstract
Patient selection is suboptimal in most studies focused on identifying biological markers for neoplastic progression in Barrett's esophagus (BE). This study aims to describe a stringently selected community-based case-control cohort of non-dysplastic BE (NDBE) patients who progressed to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) and BE patients who never progressed to be used for future biomarker studies. We identified all patients referred for endoscopic work-up of BE neoplasia at three tertiary referral centers for treatment of BE neoplasia between 2000 and 2013. We performed a detailed registration of any endoscopic surveillance history before neoplastic progression. Controls were selected from a retrospective BE surveillance registration in 10 community hospitals. A total of 887 patients were referred for endoscopic work-up of BE neoplasia. Based on predefined selection criteria, we identified 165 progressor patients (82% men; mean age 55 years ± 10.4) with a baseline endoscopy demonstrating NDBE > 2 years before neoplastic progression. Using the same predefined selection criteria, 723 nonprogressor patients (67% men; mean age 57 years ± 11.3) with >2 years of endoscopic surveillance were identified. Median length of the BE segment was 5 cm (IQR 4-7) in progressors and 4 cm (IQR 2-6) in controls. Median duration of surveillance was 89 months (IQR 54-139) in progressors and 76 months (IQR 47-116) in nonprogressors. Paraffin embedded biopsies are available for biomarker research in all patients. Ethical approval was obtained and material transfer agreements were signed with all 58 contributing pathology labs. This is the largest community-based case-control cohort of BE patients with and without progression to early neoplasia. The stringent selection criteria and the availability of paraffin embedded biopsy specimens make this a unique cohort for biomarker studies.

Abstract
Background Dysplasia assessment of Barrett’s esophagus biopsies is associated with low
observer agreement; guidelines advise expert review. We have developed a
web-based review panel for dysplastic Barrett’s esophagus biopsies. Objective The purpose of this study was to test if 10 gastrointestinal pathologists
working at Dutch Barrett’s esophagus expert centres met pre-set benchmark
scores for quality criteria. Methods Ten gastrointestinal pathologists twice assessed 60 digitalized Barrett’s
esophagus cases, enriched for dysplasia; then randomised (7520 assessments).
We tested predefined benchmark quality criteria: (a) percentage of
‘indefinite for dysplasia’ diagnoses, benchmark score ≤14% for all cases,
≤16% for dysplastic subset, (b) intra-observer agreement; benchmark score
≥0.66/≥0.39, (c) percentage agreement with ‘gold standard diagnosis’;
benchmark score ≥82%/≥73%, (d) proportion of cases with high-grade dysplasia
underdiagnosed as non-dysplastic Barrett’s esophagus; benchmark score ≤1/78
(≤1.28%) assessments for dysplastic subset. Results Gastrointestinal pathologists had seven years’ Barrett’s
esophagus-experience, handling seven Barrett’s esophagus-cases weekly. Three
met stringent benchmark scores; all cases and dysplastic subset, three met
extended benchmark scores. Four pathologists lacked one quality criterion to
meet benchmark scores. Conclusion Predefined benchmark scores for expert assessment of Barrett’s esophagus
dysplasia biopsies are stringent and met by some gastrointestinal
pathologists. The majority of assessors however, only showed limited
deviation from benchmark scores. We expect further training with group
discussions will lead to adherence of all participating gastrointestinal
pathologists to quality criteria, and therefore eligible to join the review
panel.

Abstract
Background Dysplasia in Barrett's esophagus (BE) biopsies is associated with low
observer agreement among general pathologists. Therefore, expert review is
advised. We are developing a web-based, national expert review panel for
histological review of BE biopsies. Objective The aim of this study was to create benchmark quality criteria for future
members. Methods Five expert BE pathologists, with 10–30 years of BE experience, weekly
handling 5–10 cases (25% dysplastic), assessed a case set of 60 digitalized
cases, enriched for dysplasia. Each case contained all slides from one
endoscopy (non-dysplastic BE (NDBE), n = 21; low-grade
dysplasia (LGD), n = 20; high-grade dysplasia (HGD),
n = 19). All cases were randomized and assessed twice
followed by group discussions to create a consensus diagnosis. Outcome
measures: percentage of ‘indefinite for dysplasia’ (IND) diagnoses,
intra-observer agreement, and agreement with the consensus ‘gold standard’
diagnosis. Results Mean percentage of IND diagnoses was 8% (3–14%) and mean intra-observer
agreement was 0.84 (0.66–1.02). Mean agreement with the consensus diagnosis
was 90% (95% prediction interval (PI) 82–98%). Conclusion Expert pathology review of BE requires the scoring of a limited number of IND
cases, consistency of assessment and a high agreement with a consensus gold
standard diagnosis. These benchmark quality criteria will be used to assess
the performance of other pathologists joining our panel.

Abstract
Introduction The risk of lymph node metastases (LNM) in submucosal esophageal adenocarcinoma (EAC) patients is subject to debate. These patients might be treated endoscopically if the risk of LNM appears to be low. Objective The objective of this article is to evaluate the outcome of patients who underwent an endoscopic resection (ER) and subsequent endoscopic follow-up for a submucosal EAC. Methods All patients who underwent ER for submucosal EAC between January 2012 and August 2016 and were subsequently managed with endoscopic follow-up were retrospectively identified. Primary outcome was the number of patients diagnosed with LNM; secondary outcomes included intraluminal recurrences. Results Thirty-five patients (median age 68 years) were included: 17 low-risk (submucosal invasion <500 microns, G1–G2, no lymphovascular invasion (LVI)), and 18 high-risk (submucosal invasion >500 microns, and/or G3–G4, and/or LVI, and/or a tumor-positive deep resection margin (R1)) EACs. After a median follow-up of 23 (IQR 15–43) months, in which patients underwent a median of six (IQR 4–8) endoscopies and a median of four (IQR 2–8) endoscopic ultrasound procedures, none of the included patients were diagnosed with LNM. Five (14%) patients developed a local intraluminal recurrence a median of 18 (IQR 11–21) months after baseline ER that were treated endoscopically. Conclusions In 35 patients with a submucosal EAC, no LNM were found during a median follow-up of 23 months. Endoscopic therapy may be an alternative for surgery in selected patients with a submucosal EAC.

Abstract
High-risk submucosal esophageal adenocarcinoma's might be treated curatively by means of radical endoscopic resection, followed by thoracolaparoscopic lymphadenectomy without concomitant esophagectomy. A preclinical study has shown the feasibility and safety of this approach; however, no studies are performed in a clinical setting. In addition, sentinel node navigation surgery could be valuable in tailoring the extent of the lymphadenectomy. This study aimed to evaluate the feasibility and safety of thoracolaparoscopic lymphadenectomy without esophagectomy (phase I) and sentinel node navigation surgery (phase II) in patients with early esophageal adenocarcinoma. Patients with T1N0M0 early esophageal adenocarcinoma scheduled for esophagectomy without neoadjuvant therapy were included. Phase I: Two-field, esophagus preserving, thoracolaparoscopic lymphadenectomy was performed, followed by esophagectomy in the same session. Primary outcome parameters were the number of lymph nodes resected, and number of retained lymph nodes in the esophagectomy specimen. Phase II: A radioactive tracer was injected endoscopically the day before surgery. Static imaging was performed 15 and 120 minutes after injection. The day of surgery, sentinel node navigation surgery followed by esophagectomy was performed. Primary outcome parameters were the percentage of patients with a detectable sentinel node, and the concordance between static imaging and probe-based detection of sentinel node. Phase I: Five patients were included, and a median of 30 (IQR: 25-46) lymph nodes was resected. A median of 6 (IQR: 2-9) retained lymph nodes was found in the esophagectomy specimen. No acute adverse events occurred, but near the end of lymphadenectomy esophageal discoloration was observed, possibly indicating ischemia. Phase II: In all five included patients sentinel nodes could be visualized and resected, at a median of 3 (IQR: 2-5) locations. There was a high concordance between imaging and probe-based detection of sentinel nodes. In conclusion, sentinel node navigation surgery followed by lymphadenectomy without concomitant esophagectomy seems feasible in patients with high-risk submucosal early esophageal adenocarcinoma. More evidence is however needed before applying this technique in clinical practice.

Abstract
Management of Barrett's esophagus (BE) relies heavily on histopathological assessment of biopsies, associated with significant intra- and interobserver variability. Guidelines recommend biopsy review by an expert in case of dysplasia. Conventional review of biopsies, however, is impractical and does not allow for teleconferencing or annotations. An expert digital review platform might overcome these limitations. We compared diagnostic agreement of digital and conventional microscopy for diagnosing BE ± dysplasia. Sixty BE biopsy glass slides (non-dysplastic BE (NDBE); n = 25, low-grade dysplasia (LGD); n = 20; high-grade dysplasia (HGD); n = 15) were scanned at ×20 magnification. The slides were assessed four times by five expert BE pathologists, all practicing histopathologists (range: 5-30 years), in 2 alternating rounds of digital and conventional microscopy, each in randomized order and sequence of slides. Intraobserver and pairwise interobserver agreement were calculated, using custom weighted Cohen's kappa, adjusted for the maximum possible kappa scores. Split into three categories (NDBE, IND, LGD+HGD), the mean intraobserver agreement was 0.75 and 0.84 for digital and conventional assessment, respectively (p = 0.35). Mean pairwise interobserver agreement was 0.80 for digital and 0.85 for conventional microscopy (p = 0.17). In 47/60 (78%) of digital microscopy reviews a majority vote of ≥3 pathologists was reached before consensus meeting. After group discussion, a majority vote was achieved in all cases (60/60). Diagnostic agreement of digital microscopy is comparable to that of conventional microscopy. These outcomes justify the use of digital slides in a nationwide, web-based BE revision platform in the Netherlands. This will overcome the practical issues associated with conventional histologic review by multiple pathologists.

Abstract
BACKGROUND & AIMS For patients with Barrett's esophagus, the diagnosis of low-grade dysplasia (LGD) is subjective, and reported outcomes vary. We analyzed data from a multicenter study of endoscopic therapy to identify factors associated with progression to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) in patients with LGD of the esophagus. METHODS We performed a retrospective analysis of data from 255 patients with a primary diagnosis of LGD (78% men; mean age, 63 years) who participated in a randomized controlled trial of surveillance vs radiofrequency ablation in Europe. Three expert pathologists independently reviewed baseline and subsequent LGD specimens. The presence and degree of dysplasia was separately recorded for each biopsy and classified according to the Vienna Classification system. The primary end point was development of HGD or EAC. We performed univariate logistic regression analyses to assess the association between outcomes and factors such as number of pathologists confirming LGD, multifocality of LGD, and persistence of LGD over time. RESULTS Of the 255 patients, 45 (18%) developed HGD or EAC during a median 42-month follow-up period (interquartile range, 25-61 months); patients were examined by a median 4 endoscopies (interquartile range, 3-6 endoscopies). The number of pathologists confirming LGD was strongly associated with progression to neoplasia; risk for progression increased greatly when all 3 pathologists agreed on LGD (odds ratio, 47.14; 95% confidence interval, 13.10-169.70). When LGD was detected at baseline and confirmed by a subsequent endoscopy, the odds for progression to neoplasia also increased greatly (odds ratio, 9.28; 95% confidence interval, 4.39-19.64). Multifocal LGD was not significantly associated with progression to neoplasia. CONCLUSIONS The number of pathologists confirming LGD and persistence of LGD over time increase risk for development of HGD or EAC in patients with Barrett's esophagus and LGD. These simple, readily available variables can help stratify risk and select patients for prophylactic ablation therapy.

Abstract
OBJECTIVE Focal endoscopic resection (ER) followed by radiofrequency ablation (RFA) safely and effectively eradicates Barrett's oesophagus (BO) containing high-grade dysplasia (HGD) and/or early cancer (EC) in smaller studies with limited follow-up. Herein, we report long-term outcomes of combined ER and RFA for BO (HGD and/or EC) from a single-arm multicentre interventional study. DESIGN In 13 European centres, patients with BO ≤ 12 cm with HGD and/or EC on 2 separate endoscopies were eligible for inclusion. Visible lesions (<2 cm length; <50% circumference) were removed with ER, followed by serial RFA every 3 months (max 5 sessions). Follow-up endoscopy was scheduled at 6 months after the first negative post-treatment endoscopic control and annually thereafter. OUTCOMES complete eradication of neoplasia (CE-neo) and intestinal metaplasia (CE-IM); durability of CE-neo and CE-IM (once achieved) during follow-up. Biopsy and resection specimens underwent centralised pathology review. RESULTS 132 patients with median BO length C3M6 were included. After entry-ER in 119 patients (90%) and a median of 3 RFA (IQR 3-4) treatments, CE-neo was achieved in 121/132 (92%) and CE-IM in 115/132 patients (87%), per intention-to-treat analysis. Per-protocol analysis, CE-neo and CE-IM were achieved in 98% and 93%, respectively. After a median of 27 months following the first negative post-treatment endoscopic control, neoplasia and IM recurred in 4% and 8%, respectively. Mild-to-moderate adverse events occurred in 25 patients (19%); all managed conservatively or endoscopically. CONCLUSIONS In patients with early Barrett's neoplasia, intensive multimodality endotherapy consisting of ER combined with RFA is safe and highly effective, and the treatment effect appears to be durable during mid-term follow-up.

Abstract
OBJECTIVE Reported malignant progression rates for low-grade dysplasia (LGD) in Barrett's oesophagus (BO) vary widely. Expert histological review of LGD is advised, but limited data are available on its clinical value. This retrospective cohort study aimed to determine the value of an expert pathology panel organised in the Dutch Barrett's Advisory Committee (BAC) by investigating the incidence rates of high-grade dysplasia (HGD) and oesophageal adenocarcinoma (OAC) after expert histological review of LGD. DESIGN We included all BO cases referred to the BAC for histological review of LGD diagnosed between 2000 and 2011. The diagnosis of the expert panel was related to the histological outcome during endoscopic follow-up. Primary endpoint was development of HGD or OAC. RESULTS 293 LGD patients (76% men; mean 63 years±11.9) were included. Following histological review, 73% was downstaged to non-dysplastic BO (NDBO) or indefinite for dysplasia (IND). In 27% the initial LGD diagnosis was confirmed. Endoscopic follow-up was performed in 264 patients (90%) with a median follow-up of 39 months (IQR 16-72). For confirmed LGD, the risk of HGD/OAC was 9.1% per patient-year. Patients downstaged to NDBO or IND had a malignant progression risk of 0.6% and 0.9% per patient-year, respectively. CONCLUSIONS Confirmed LGD in BO has a markedly increased risk of malignant progression. However, the vast majority of patients with community LGD will be downstaged after expert review and have a low progression risk. Therefore, all BO patients with LGD should undergo expert histological review of the diagnosis for adequate risk stratification.

Abstract
IMPORTANCE Barrett esophagus containing low-grade dysplasia is associated with an increased risk of developing esophageal adenocarcinoma, a cancer with a rapidly increasing incidence in the western world. OBJECTIVE To investigate whether endoscopic radiofrequency ablation could decrease the rate of neoplastic progression. DESIGN, SETTING, AND PARTICIPANTS Multicenter randomized clinical trial that enrolled 136 patients with a confirmed diagnosis of Barrett esophagus containing low-grade dysplasia at 9 European sites between June 2007 and June 2011. Patient follow-up ended May 2013. INTERVENTIONS Eligible patients were randomly assigned in a 1:1 ratio to either endoscopic treatment with radiofrequency ablation (ablation) or endoscopic surveillance (control). Ablation was performed with the balloon device for circumferential ablation of the esophagus or the focal device for targeted ablation, with a maximum of 5 sessions allowed. MAIN OUTCOMES AND MEASURES The primary outcome was neoplastic progression to high-grade dysplasia or adenocarcinoma during a 3-year follow-up since randomization. Secondary outcomes were complete eradication of dysplasia and intestinal metaplasia and adverse events. RESULTS Sixty-eight patients were randomized to receive ablation and 68 to receive control. Ablation reduced the risk of progression to high-grade dysplasia or adenocarcinoma by 25.0% (1.5% for ablation vs 26.5% for control; 95% CI, 14.1%-35.9%; P < .001) and the risk of progression to adenocarcinoma by 7.4% (1.5% for ablation vs 8.8% for control; 95% CI, 0%-14.7%; P = .03). Among patients in the ablation group, complete eradication occurred in 92.6% for dysplasia and 88.2% for intestinal metaplasia compared with 27.9% for dysplasia and 0.0% for intestinal metaplasia among patients in the control group (P < .001). Treatment-related adverse events occurred in 19.1% of patients receiving ablation (P < .001). The most common adverse event was stricture, occurring in 8 patients receiving ablation (11.8%), all resolved by endoscopic dilation (median, 1 session). The data and safety monitoring board recommended early termination of the trial due to superiority of ablation for the primary outcome and the potential for patient safety issues if the trial continued. CONCLUSIONS AND RELEVANCE In this randomized trial of patients with Barrett esophagus and a confirmed diagnosis of low-grade dysplasia, radiofrequency ablation resulted in a reduced risk of neoplastic progression over 3 years of follow-up.

Abstract
BACKGROUND AND STUDY AIMS Radiofrequency ablation (RFA) with or without prior endoscopic resection safely and effectively removes early neoplasia in Barrett's esophagus. We speculated that this approach might also be suited for early squamous neoplasia of the esophagus. The aim of the study was to assess our initial experiences with RFA for high grade intraepithelial neoplasia (HGIN) and esophageal squamous cell cancer (ESCC) limited to the mucosa. PATIENTS AND METHODS This was a prospective case series study in two tertiary centers. Patients with at least one unstained lesion (USL) of the esophagus using Lugol's chromoendoscopy and squamous HGIN/ESCC upon biopsy were included. In the case of nonflat USLs, endoscopic resection was performed for staging and to render the mucosa flat. After endoscopic resection and subsequent circumferential RFA, chromoendoscopy was repeated every 3 months with focal RFA of residual USLs. Follow-up chromoendoscopy was repeated at 6 months and annually thereafter. The main outcome measure was complete histological response for any squamous intraepithelial neoplasia or ESCC. RESULTS A total of 13 patients (10 HGIN, three ESCC) were included. Following endoscopic resection in nine patients, the median extent of USLs was 4 cm and 50 % of circumference. All 13 patients achieved a complete response after a median of 2 RFA sessions (IQR 1 - 3 sessions). RFA-related complications included two mucosal lacerations (at the endoscopic resection scar) and one intramural hematoma, none requiring therapy. Endoscopic resection-/RFA-related complications were three stenoses. Dilation resulted in perforation in one patient (managed with a covered stent). There were no recurrences (median follow-up 17 months [IQR 11 - 22 months]). CONCLUSIONS This study suggests that RFA with or without prior endoscopic resection for esophageal squamous HGIN and mucosal ESCC is feasible and effective.

Abstract
INTRODUCTION Multiband mucosectomy (MBM) is a relatively new technique for endoscopic resection in Barrett's esophagus. This ligate-cut technique uses a modified variceal band ligator allowing for six consecutive resections without prior submucosal lifting. The aim was to evaluate the safety of MBM and its efficacy for complete endoscopic removal of delineated target areas in Barrett's esophagus. METHODS Prospective registration of all MBM procedures in Barrett's esophagus was carried out between November 2004 and October 2009 in two hospitals. Prior to MBM, the target area was delineated with coagulation markings, followed by endoscopic resection until the delineated area was completely resected. Primary end points were acute (during procedure) plus early complications (<30 days) and the rate of complete endoscopic resection of the delineated target area. RESULTS A total of 243 MBM procedures, with 1060 resections, were performed in 170 patients. MBM was performed for focal lesions (n=113), for Barrett's esophagus removal as part of a (stepwise) radical endoscopic resection protocol (n=117), and as escape treatment after radiofrequency ablation (n=13). The only acute complication was bleeding (in 3%, endoscopically managed); no perforations occurred despite absence of submucosal lifting. Early complications consisted of delayed bleeding (in 2%, endoscopically managed) and stenosis, which occurred in 48% of patients treated in a (stepwise) radical resection protocol; patients treated for focal lesions or in escape treatment showed no stenosis. Complete endoscopic resection was achieved in 91% of the focal lesions, in 86% of cases treated under the (stepwise) radical endoscopic resection protocol, and 100% for escape treatment after radiofrequency ablation. CONCLUSION MBM is a safe and effective technique for the removal of delineated target areas in Barrett's esophagus.

Abstract
BACKGROUND Endoscopic trimodal imaging (ETMI) may improve detection of early neoplasia in Barrett's esophagus (BE). Studies with ETMI so far have been performed in tertiary referral settings only. OBJECTIVE To compare ETMI with standard video endoscopy (SVE) for the detection of neoplasia in BE patients with an intermediate-risk profile. DESIGN Multicenter, randomized, crossover study. SETTING Community practice. PATIENTS AND METHODS BE patients with confirmed low-grade intraepithelial neoplasia (LGIN) underwent both ETMI and SVE in random order (interval 6-16 weeks). During ETMI, BE was inspected with high-resolution endoscopy followed by autofluorescence imaging (AFI). All visible lesions were then inspected with narrow-band imaging. During ETMI and SVE, visible lesions were sampled followed by 4-quadrant random biopsies every 2 cm. MAIN OUTCOME MEASUREMENTS Overall histological yield of ETMI and SVE and targeted histological yield of ETMI and SVE. RESULTS A total of 99 patients (79 men, 63±10 years) underwent both procedures. ETMI had a significantly higher targeted histological yield because of additional detection of 22 lesions with LGIN/high-grade intraepithelial neoplasia (HGIN)/carcinoma (Ca) by AFI. There was no significant difference in the overall histological yield (targeted+random) between ETMI and SVE. HGIN/Ca was diagnosed only by random biopsies in 6 of 24 patients and 7 of 24 patients, with ETMI and SVE, respectively. LIMITATIONS Inspection, with high-resolution endoscopy and AFI, was performed sequentially. CONCLUSION ETMI performed in a community-based setting did not improve the overall detection of dysplasia compared with SVE. The diagnosis of dysplasia is still being made in a significant number of patients by random biopsies. Patients with a confirmed diagnosis of LGIN have a significant risk of HGIN/Ca.

Abstract
OBJECTIVE To evaluate the effect of the use of ultrasonography (US) and optional computed tomography (CT) or diagnostic laparoscopy on the percentage of unnecessary appendectomies in patients with suspected acute appendicitis. DESIGN Prospective and comparison with a historical control group. METHOD Following the introduction of ultrasound imaging as an initial step, the outcomes in all patients presenting with suspected appendicitis in the emergency department were prospectively collected during a period of 18 months (July 2006-December 2007). Results were compared to retrospectively collected data on all patients who had undergone appendectomy for acute appendicitis in 2001, before the introduction of this imaging investigation. RESULTS Of the 312 consecutive patients in the emergency department with suspected acute appendicitis, the condition was excluded in 51 patients following clinical and laboratory investigation. The diagnostic algorithm was applied in 239 of the 261 patients (92%). All of them had initial US, followed by additional CT in 75 patients (31%) and diagnostic laparoscopy in 12 patients (5%). Appendectomy was performed in 130 patients, and 8 (6%) of the appendices were shown to be healthy following pathological investigation. Before the implementation of preoperative imaging 36 of the 170 appendices (21%) were healthy. Following the introduction of imaging techniques in accordance with the guideline there was a significant reduction in the percentage of unnecessary appendectomies (21% versus 6%; p < 0,001). The complete supplementary diagnostic algorithm had a positive and negative predictive value of respectively 90% and 98% for acute appendicitis. CONCLUSION Structural implementation of US with optional CT and diagnostic laparoscopy in patients with suspected acute appendicitis resulted in a lower percentage of unnecessary appendectomies.

Abstract
INTRODUCTION Thrombosis and infections are well known complications of central venous catheters and totally implanted access ports. These complications lead to increased costs due to prolonged hospitalisation, increased antibiotics use and need for replacement. The objectives of the study were to document the occurrence of catheter related thrombosis and infections in patients with central venous catheters and totally implanted chest ports in cancer patients and to investigate whether factor V Leiden is a risk factor for catheter related thrombosis. MATERIALS AND METHODS Between February 2002 and November 2004, 43 patients with central venous catheter or totally implanted access port were followed up to document the occurrence of catheter related thrombosis and infections. Patients received chemotherapy either for haematological malignancy or for solid tumours. Factor V Leiden (R506Q) was determined by restriction fragment length polymorphism analysis. Follow-up period ended in April 2007. RESULTS Catheter related thrombosis occurred in 4 patients (4/43; 9.3%) with a totally implanted access port. None of the 3 patients with factor V Leiden had catheter related infection or thrombosis. Catheter related infections occurred in 15 patients: 10 patients (23.3%; 10/43) with central venous catheter and 5 patients (11.6%; 5/43) with totally implanted access ports. Time to infection was 32.5 days in the central venous catheter group compared to 88 days in the totally implanted access port group. CONCLUSION A higher incidence of catheter related infections was observed in patients with central venous catheters in contrast to patients with totally implanted access ports were venous thrombosis was more frequent.

Abstract
OBJECTIVE To determine whether men and women differ in the histological characteristics of plaque material removed at carotid endarterectomy. DESIGN Observational and descriptive. METHODS Carotid endarterectomy plaque specimens obtained from 45 degrees consecutive patients (135 women, 315 men) were assessed for the presence of macrophages, smooth muscle cells, collagen, calcifications, and luminal thrombus by means ofimmunohistochemical staining. The plaques were categorised in 3 phenotypes according to the overall presentation of histological characteristics and the lipid level. Protein was isolated from the plaques to determine the interleukin-6 (IL-6) and IL-8 concentrations and the activity of matrix metalloproteinase-8 (MMP-8) and MMP-9. RESULTS Atheromatous plaques (> 40% fat) were less frequently observed in women than in men (22 versus 40%; p < 0.001). In addition, more women than men had a low macrophage staining (18 versus 11%; p = 0.05) and strong smooth muscle cell staining (38 versus 24%; p = 0.001). Compared with men, women had a lower plaque concentration of IL-8 and lower MMP-8 activity. The observed differences were most pronounced in the asymptomatic group. An atheromatous plaque occurred in 9% of asymptomatic women compared to 39% ofasymptomatic men (p = 0.02). Moreover, a large proportion of plaques obtained from asymptomatic women showed high smooth muscle cell content (53 versus 30%; p = 0.03) and high collagen content (55 versus 24%; p = 0.003). All relations between gender and plaque characteristics, except for MMP-8, remained the same in a multivariate analysis that was adjusted for clinical presentation and other cardiovascular risk factors. CONCLUSION Women with a carotid stenosis had more stable plaques than men, independent of clinical presentation and cardiovascular risk profile. Asymptomatic women demonstrated the highest prevalence of stable plaques. These findings may explain why women benefit less from carotid endarterectomy than men.

Abstract
BACKGROUND The majority of sentinel node (SN) positive breast cancer patients do not have additional non-SN involvement and may not benefit from axillary lymph node dissection (ALND). Previous studies in melanoma have suggested that microanatomic localization of SN metastases may predict non-SN involvement. The present study was designed to assess whether these criteria might also be used to be more restrictive in selecting breast cancer patients who would benefit from an ALND. METHODS A consecutive series of 357 patients with invasive breast cancer and a tumor-positive axillary SN, followed by an ALND, was reviewed. Microanatomic SN tumor features (subcapsular, combined subcapsular and parenchymal, parenchymal, extensive localization, multifocality, and the penetrative depth from the SN capsule) were evaluated for their predictive value for non-SN involvement. RESULTS Non-SN metastases were found in 136/357 cases (38%). Microanatomic location and penetrative depth of SN metastases were significant predictors for non-SN involvement (<0.001); limited penetrative depth was associated with a low frequency of non-SN involvement with a minimal of 10%. CONCLUSIONS Microanatomic location and penetrative depth of breast cancer SN metastases predict non-SN involvement. However, based on these features no subgroup of patients could be selected with less than 10% non-SN involvement.

Abstract
Acquired hypertrichosis lanugo-type or hypertrichosis lanuginosa acquisita (HLA) is often associated with metabolic and endocrine disorders and use of certain drugs. The occurrence of HLA with malignancy was first noted in 1865, and it has since been described in 56 patients as a paraneoplastic syndrome both in women and in men. Sometimes HLA occurs concurrent with acanthosis nigricans, papillary hypertrophy of the tongue, and glossitis. The predominance of female cases is striking. Malignancy-associated HLA seems to occur especially in the age group 40-70 years. In women with HLA the most frequent malignancy is colorectal cancer, followed in order by lung cancer and breast cancer; in men lung cancer is the malignancy most frequently associated with HLA, followed by colorectal cancer. In 3 years we saw 10 patients with HLA, in whom the malignancy was usually metastasized. Only one patient had local disease; after removal of the primary tumour it took 2 years before the lanugo hair recurred. The aetiology of the syndrome is not clear: no specific hormonal or biochemical abnormalities have been identified as yet. The difference between hirsutism and lanugo-type hypertrichosis is discussed. It is stressed that the appearance of lanugo-type hypertrichosis in body areas previously perceived by patients as 'hairless' is highly indicative of internal malignancy.

Abstract
Temporal arteritis (TA) may offer major complications, whilst high dosage of prednisone may result in serious side effects. We tried to identify a subgroup of TA, which can be treated with a lower dosage of prednisone. Retrospectively, clinical and laboratory data were studied at presentation, as well as the outcome in 44 consecutive patients with biopsy-proven temporal arteritis. These data were related to three particular histological subgroups, (a) classical giant cell arteritis, (b) atypical arteritis, and (c) 'healed arteritis', defined according to Allsop and Gallagher (The American Journal of Surgical Pathology 5:317-332, 1981). At presentation in subgroup c, erythrocyte sedimentation rate was lower and the level of haemoglobin was higher than in the other two subgroups. During follow-up in the healed arteritis group, reactivation, recurrence, or early death were not observed, whilst prednisone dosage after 2 and 3 years was lower compared to subgroup b. Major complications (permanent blindness and cerebrovascular accident) were only observed in subgroups a and b. We believe that the healed arteritis subgroup represents a relatively benign subgroup with a mild clinical presentation and a good prognosis. Therefore, a much lower initial prednisone dosage (15 mg/day) is suggested for patients in subgroup c than in the other two subgroups (40-60 mg/day).

Abstract
BACKGROUND AND AIMS Ezetimibe was introduced recently as a new class of cholesterol-lowering drugs. Until now only limited increases of transaminase levels were reported. METHODS We studied 2 patients with severe hepatic side effects of ezetimibe in a general community hospital. RESULTS Ezetimibe may lead to 2 distinct types of severe hepatic side effects. CONCLUSIONS Ezetimibe may rarely cause hepatotoxicity, severe cholestatic hepatitis, or acute autoimmune hepatitis.

Abstract
OBJECTIVE To calculate the number of cervical mediastinoscopies that need not be carried out ifoesophageal endoscopic ultrasound and fine-needle aspiration biopsy (EUS-FNA) are included in the staging of patients with non-small-cell lung carcinoma (NSCLC). DESIGN Retrospective, descriptive. METHOD Patients referred to the St. Antonius Hospital in Nieuwegein, the Netherlands, with NSCLC from January to December 2003 routinely underwent EUS-FNA during the staging process. If mediastinal or distant metastases were found to be present then cervical mediastinoscopy was not carried out as the patient was not eligible for operation. If no metastases were demonstrated then cervical mediastinoscopy was carried out. The value of EUS-FNA was calculated. RESULTS A total of 43 patients underwent EUS-FNA: 32 men and 11 women with an average age of 64 (range: 45-77). In 22 (51%) of them, cervical mediastinoscopy was not performed as EUS-FNA demonstrated malignant cells in the lymph nodes of the mediastinum or abdomen, in the left adrenal gland or in the primary tumour which had grown into the mediastinum. In 2 of the 21 other patients malignant cells were found on mediastinoscopy showing the EUS-FNA results in 2 of 43 patients (5%) to be false-negative. No complications occurred. CONCLUSION Based on the findings from EUS-FNA, cervical mediastinoscopy was not performed in 51% of the patient group.

Abstract
Three patients, two Moroccan men aged 27 and 25 and a Turkish man aged 25, presented with haemoptysis caused by pulmonary aneurysm. The aneurysms had formed as a complication of Behçet's disease. Two of them were treated with high doses of corticosteroids. One man recovered and another died as a consequence of massive haemoptysis. The third man underwent emergency thoracotomy and pneumectomy due to massive haemoptysis. Postoperatively he was treated with cyclosporine resulting in full recovery. Behçet's disease is a multisystem vasculitis characterised by orogenital ulcerations and uveitis. In a minority of cases pulmonary aneurysms develop, often causing massive haemoptysis. Aneurysms are often accompanied by venous thrombosis. Treatment consists of immunosuppressive therapy. Nevertheless a considerable number of patients die following massive haemoptysis.

Abstract
OBJECTIVE The extent of atherosclerotic plaque burden and the incidence of atherosclerosis-related cardiovascular events accelerate with increasing age. The composition of the plaque is associated with plaque thrombosis and acute coronary occlusion. Surprisingly, however, the relation between advancing age and atherosclerotic plaque composition is still unclear. In the present study, we investigated the association between plaque characteristics and advancing age in a population of patients with haemodynamically significant carotid artery stenosis. METHODS Patients (N=383), ages 39-89 years, underwent carotid endarterectomy (CEA). Morphometric analysis was performed on the dissected atherosclerotic plaques to study the prevalence of fibrous and atheromatous plaques. Picro sirius red, haematoxylin eosin, alfa actin and CD68 stainings were performed to investigate the extent of collagen, calcification, smooth muscle cells and macrophages in carotid plaques, respectively. The presence of metalloproteinases-2 and -9 was assessed by ELISA. RESULTS With aging, a decrease in fibrous plaques and an increase in atheromatous plaques were observed. This was accompanied by an age-associated decrease in smooth muscle cell content in carotid plaques. Macrophage content slightly increased with age. In addition, total matrix metalloprotease (MMP)-2 was negatively and MMP-9 positively related with age. Differences in plaque phenotype were most prominent for the youngest age quartile compared with older age quartiles. CONCLUSIONS With increasing age, the morphology of atherosclerotic plaques from patients with carotid artery stenosis changes. Plaques become more atheromatous and contain less smooth muscle cells with increasing age. Local inflammation and MMP-9 levels slightly increased with age in plaques obtained from patients suffering from haemodynamically significant advanced atherosclerotic lesions.

Abstract
In clinical practice, biological markers are not available to routinely assess the progression of atherosclerotic disease or the development of restenosis following endarterectomy or catheter based interventions. Endarterectomy procedures provide an opportunity to study mechanisms of restenosis and progression of atherosclerotic disease since atherosclerotic tissue is obtained. Athero-Express is an ongoing prospective study, initiated in 2002, with the objective to investigate the etiological value of plaque characteristics for long term outcome. Patients are included who undergo an endarterectomy of the carotid artery. At baseline blood is withdrawn, patients fill in an extensive questionnaire and diagnostic examinations are performed. Atherosclerotic plaques are freshly harvested, immunohistochemically stained and examined for the presence of macrophages, smooth muscle cells, collagen and fat. Parts of the atherosclerotic plaques are freshly frozen to study protease activity and protein and RNA expressions. Patients undergo a duplex follow up to assess procedural restenosis (primary endpoint) at 3 months, 1 year and 2 years. Secondary endpoints encompass major adverse cardiovascular events. In the future, the creation of this biobank with atherosclerotic specimen will allow the design of cross-sectional and follow up studies with the objective to investigate the expression of newly discovered genes and proteins and their interaction with patients and plaque characteristics in the progression of atherosclerotic disease. Objective is to include 1000-1200 patients in 5 years. In January 2004, 289 patients had been included. It is expected that 250 patients will be included yearly.

Abstract
Over the course of a few years, an obese 52-year-old woman with a 23-year history of hypertension developed a number of abdominal complaints including gall stones. Her blood pressure became increasingly difficult to control and she developed diabetes mellitus and suffered palpitations and headaches. It became noticeable that she had a moon face. Laboratory tests revealed hypercortisolism. CT-scan showed a large inhomogeneous mass of nine centimetres in her left adrenal gland, which was subsequently removed surgically. The histopathological diagnosis was consistent with an adenoma. After a number of months the patient developed bone and liver metastases and the diagnosis was amended to carcinoma of the adrenal cortex. She then underwent radiotherapy and chemotherapy treatment. One year after surgery she developed a pancytopenia and died. Adrenocortical carcinomas are rare tumours with an incidence of about 1-2 cases per million of the population. Symptoms are heterogeneous since both functional (hormonal overproduction) and non-functional (mass effect) tumours exist. Surgical resection is the only curative therapy. It may be difficult to distinguish between benign and malignant cortical tumours.

Abstract
Pulmonary carcinoid tumors are neuroendocrine malignant tumors that make up 1% to 2% of all lung tumors. According to histopathologic criteria, carcinoids can be divided into typical (TC) and atypical (AC) carcinoids. Carcinoids can be placed in a spectrum of neuroendocrine tumors, ranging from low-grade malignant TC to intermediate AC to high-grade large-cell neuroendocrine carcinoma and small-cell lung carcinoma. Familial pulmonary carcinoids are rare. The most common symptoms are hemoptysis, cough, recurrent pulmonary infection, fever, chest discomfort and chest pain, unilateral wheezing, and shortness of breath. Paraneoplastic syndromes are rare and include carcinoid syndrome, Cushing's syndrome, and ectopic growth hormone-releasing hormone secretion. The diagnosis is usually established by flexible bronchoscopy and biopsy, although occasionally this can result in severe hemorrhage. Immunoscintigraphy by somatostatin analogs can also be useful in diagnosis. The treatment of choice is surgical resection, and prognosis is relatively good in TC, although it is worse in AC. The role of radiotherapy and chemotherapy as part of multimodality treatment or palliation is still debated.

Abstract
We report the first occurrence of gemcitabine-induced vasculitis. It concerns a 45-year-old man diagnosed with non-small lung cancer since 2 months. After the first cycle of chemotherapy, consisting of gemcitabine and cisplatin, he developed myalgia and swelling of arms and legs with impairment of movement. This re-occurred during the second cycle of chemotherapy. Further anemia, elevated ESR and increased creatininephosphokinase. A surgical biopsy showed leucocytoclastic vasculitis and necrosis of muscle tissue. The chemotherapy was stopped and the complaints disappeared and did not return.

Abstract
Carditis has become the subject of much study and discussion, although its etiology is still controversial. We wished to study the prevalence and possible pathogenetic mechanisms of carditis in a well-defined group of patients. In 664 patients biopsies were taken distal to the squamocolumnar junction (SCJ) and from the endoscopically defined cardia (2 cm below proximal margin of gastric folds). Specimens were stained with hematoxylin and eosin, Alcian blue, and modified Giemsa. Type of mucosa, inflammatory and metaplastic changes, and presence of Helicobacter pylori (Hp) were graded. Most of the patients had a normal appearing SCJ on endoscopy; 19.3% had short columnar segments (1-3 cm). In the first group cardiac/mixed mucosa was found in 71.9% of SCJ biopsies, and carditis (90.6%) was associated with Hp. In the second group, cardiac/mixed mucosa was present in 80.5%. There was a trend for an association between carditis (87.4%) and reflux esophagitis and hiatal hernia. Biopsies from the endoscopically defined cardia rarely contained cardiac/mixed mucosa (12.6%). These findings suggest two etiologies for carditis. In a normal-appearing SCJ carditis is associated with Hp, whereas in an irregular SCJ with short columnar segments/tongues carditis is associated with features of gastroesophageal reflux.

Abstract
BACKGROUND AND AIMS It has been shown that gastro-oesophageal reflux plays a role in the pathogenesis of intestinal metaplasia (IM) limited to the oesophagogastric junction (OGJ), similar to the pathogenesis of IM in long segments of columnar lined oesophagus. The aim of this study was to examine lower oesophageal sphincter (LOS) function by means of prolonged recording in patients with IM limited to a normal appearing OGJ. PATIENTS AND METHODS Eighteen patients with IM at the OGJ (five females, 13 males; mean age 55.4 years) and 22 patients without IM (nine females, 13 males; mean age 53.9 years) underwent conventional stationary oesophageal manometry. Thereafter, seven hour water perfused manometry with simultaneous pH measurement (probe 5 cm proximal to the LOS) was performed. Swallowing was monitored with a pharyngeal sidehole and LOS pressure was recorded with a Dent sleeve. Patients were studied in the fasted state (three hours) and after a standardised meal (four hours). LOS pressure was analysed using customised software, and the incidence of reflux episodes (pH <4 for at least five seconds) and transient LOS relaxations (TLOSRs) were examined. TLOSRs were judged to be accompanied by reflux if a decrease of 1 pH unit occurred during relaxation. RESULTS Patients with IM at the OGJ had a higher prevalence of postprandial acid reflux compared with patients without IM. No differences were observed in LOS pressure (pre- and postprandially) or in the prevalence of TLOSRs. However, in the postprandial phase, the rate of TLOSRs accompanied by acid reflux was increased in patients with IM. CONCLUSION Patients with IM at the OGJ have a higher prevalence of postprandial acid reflux. This is not associated with a higher prevalence of TLOSRs or a decreased LOS pressure but with a higher rate of TLOSRs accompanied by reflux.

Abstract
OBJECTIVE Intestinal metaplasia (IM) close to the oesophagogastric junction (OGJ) has become a focus of research interest against a background of the rising incidence of malignancies in that area. Studies have focused on the presence of IM in short columnar segments (0-3 cm). Recently it has been suggested that IM at the OGJ and IM in short columnar segments may represent different entities. The objective of this current study was to determine the prevalence of IM in these areas and to assess clinical characteristics in order to test the hypothesis that IM at the OGJ and IM in short columnar segments are different entities. METHODS Six hundred and fifty-eight patients referred for gastroscopy, in whom a columnar lining of 0-3 cm was found, participated in the study. Endoscopic oesophagitis was graded, distances to endoscopic landmarks were measured, and biopsies (antrum, corpus, 'cardia', and immediately distal to the squamocolumnar junction) were taken. Biopsies were stained with haematoxylin & eosin, Alcian Blue (pH 2.5), modified Giemsa for Helicobacter pylori (Hp), and immunohistochemistry in cases of a negative Giemsa. According to endoscopy, patients were categorized as having a normal OGJ (0-1 cm) or having a short columnar segment (1 -3 cm, tongues >1 cm). RESULTS In this study 77.7% of patients had a normal OGJ (IM-positive 15.1%), and 22.3% had a short columnar segment (IM-positive 29.3%). In the first group, IM was correlated with Hp (P = 0.003) and antral IM (P = 0.002), in the second IM was associated with the presence of a hiatal hernia (P < 0.001) and reflux oesophagitis (P = 0.023). CONCLUSION These findings suggest that IM at the OGJ is not the same entity as IM in short columnar segments.

Abstract
Barrett's oesophagus is a condition where the distal oesophagus is lined with columnar epithelium. For the diagnosis intestinal metaplasia has to be found and a minimal length of 3 cm is required for the columnar-lined segment. It is well known that patients with the traditional Barrett's oesophagus have a higher risk of developing adenocarcinomas in the metaplastic segment. The clinical significance of shorter metaplastic segments and intestinal metaplasia at the gastro-oesophageal junction is much less certain. Different definitions are in use and the increasing number of studies dealing with these mucosal changes therefore may create confusion. In this article, the current knowledge concerning epidemiology, pathophysiology, clinical associations, diagnostic possibilities including endoscopy, pathology, measurement of differences in electrical potential, and treatment of columnar-lined oesophagus of any length and of intestinal metaplasia at the gastro-oesophageal junction is reviewed. Furthermore, the need for a consistent definition is emphasized.

Abstract
A 53 year-old Moroccan woman presented with a tender parasternal mass. Computerized tomography showed a mediastinal mass protruding through the sternum. Cytologic examination of fluid collected from the mass repeatedly showed acute inflammation. Tuberculostatics were started. Since patient did not improve on tuberculostatics, a small supraclavicular lymph node was removed. Histologic examination showed Morbus Hodgkin of the nodular sclerosing type. Ultimately, cytologic examination of fluid from the parasternal mass showed atypical cells. Response on chemotherapy was excellent with complete disappearance of the parasternal mass. This is a very unusual extranodal presentation of Hodgkin's disease.

Abstract
BACKGROUND Splice variants of CD44 play a causal role in the metastatic spread of pancreatic carcinoma in the rat. In previous studies we have shown that homologues of these CD44 isoforms (CD44v6) are overexpressed during colorectal tumorigenesis in man and that CD44v6 overexpression is associated with an unfavorable prognosis in this disease. In the present study we have assessed the prognostic significance of CD44 variants containing exon v5. In addition, we have used a panel of different antibodies against CD44v6 and applied a combined scoring system to improve its value as prognosticator. METHODS Expression of CD44 variants was studied by immunohistochemistry on frozen tissue sections, and the prognostic value of the CD44 variant expression was assessed using univariate and multivariate analysis. RESULTS Our studies show that expression of CD44v6, but not CD44v5, has significant prognostic value. Analysis of CD44v6 expression by means of a combined scoring system, on the basis of a panel of three different monoclonal antibodies (mAbs), makes CD44v6 a highly significant prognostic marker that is independent of Dukes stage, tumor grade, or tumor localization. CONCLUSION Assessment of CD44v6 expression by a combination of mAbs yields an independent prognosticator that may be of value in identifying patients with a high propensity to develop distant metastasis.

Abstract
PURPOSE We evaluated the prognostic impact of neuroendocrine differentiation in prostate cancer with regard to the onset of endocrine therapy failure. MATERIALS AND METHODS A retrospective study was performed on 72 transurethral resection specimens from patients who subsequently underwent endocrine therapy for prostate cancer and were followed for 44 to 95 months. Progression-free interval was recorded. Distribution pattern and proportion of neuroendocrine cells were examined in transurethral resection specimens. Neuroendocrine cells were identified based on immunoreactivity for chromogranin A. RESULTS Of 32 patients with progressive disease 27 died of prostate cancer. Chromogranin A positive cells were found in 40 of the 72 prostate cancers (55%). In a Cox proportional hazards analysis neuroendocrine differentiation of the tumor showed a negative correlation with progression-free survival (p = 0.022), which proved to be independent of the Gleason score (p < 0.001). CONCLUSIONS Our results support the view that neuroendocrine differentiation in prostatic adenocarcinomas is a prognostic factor for progressive disease under subsequent endocrine therapy. This prognosticator acts independently of tumor grade.

Abstract
Kikuchi's lymphadenitis was first recognized almost 25 years ago in Japan as a histopathologically specific reactive lymphadenitis without clear clinical correlates. The benign self-limiting clinical course and the notorious danger of misdiagnosis as malignant lymphoma together make it important to recognize this lymph node reaction type. We describe 2 typical case histories-young women with a cervical localisation.

A 49-year-old female with rheumatoid arthritis developed liver cirrhosis after a cumulative dosage of 6 g methotrexate (MTX). There were mild liver enzyme abnormalities, decreased liver synthesis function and possible signs of portal hypertension. After stopping MTX all laboratory abnormalities disappeared except for a mild thrombocytopenia. Risk factors and guidelines for monitoring liver toxicity during MTX treatment in rheumatoid arthritis are discussed.
